Psychology 3

Question 1

Behavioral Genetics

• Genes, Temperament, and Heredity
  
  • Define “Temperament”
    
    • When is one’s temperament established?
    • How does it change throughout one’s life span?

Answer 1

TEMPERAMENT

• Describes one’s general emotional disposition
• Temperament has been shown to be established at birth and relatively persistent across the life span

Question 1

Behavioral Genetics

• Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment

Interdependence of Genes & Environment

• Scenario #3: Same Genes, Different Environment

Answer 1

Environment⇒Disease OR No Disease

• In many cases, a gene will remain phenotypically irrelevant in the absence of disease-inducing environmental conditions
  
  • Genetic mutations that result in loss of enzymatic function are prime examples
    
    • e.g., PKU, galactosemia
      
      • A child born with galactosemia lacks one or more enzymes specific to the metabolism of galactose
      • The results can be fatal
      • However, if the child is kept on a low-galactose diet (environmental change), the disease has essentially no harmful effect

Question 1

Behavioral Genetics

• Nature vs. Nurture Study Methods
  
  • A less-frequent Twin Study design type is to compare the frequency of a trait among DZ (fraternal; non-identical) twins raised together to the frequency of that same trait among DZ twins raised apart
  • Why is this design less likely to be employed?
  • What are its potential limitations?

Answer 1

The population of DZ twins raised apart is considerably smaller

• ​∴ access to this limited population can be challenging

This particular design can also be problematic because:

• DZ twins are no more genetically similar than any non-twin siblings
• There would be a host of potential confounding variables
  
  • …that might have contributed to the NEED to rear the twins separately
    
    • i.e. overall lack of consistency all-around

Question 1

Behavioral Genetics

Genetically-based Behavior Variation in Natural Populations

• Do the following hypothetical findings, if true, most support a genetic influence on behavior (nature), or an environmental influence on behavior (nurture)? Why?
  1. Bipolar Disorder is more likely among individuals who have a sibling who has been diagnosed with Bipolar Disorder
  2. Adopted children who exhibit aggressive behavior are more likely to have a biological parent who also exhibits aggressive behaviors than they are to have an adoptive parent who exhibits aggressive behaviors
  3. The concordance rate for alcoholism among MZ twins raised together is higher than the concordance rate for MZ twins raised apart
  4. MZ twins raised together have more similar IQs than do DZ twins raised together
  5. Strain X of MZ twin rats had a hereditary disposition toward obesity, while Strain Y did not
  
  • Both strains were divided into groups and fed either a below-average amount of food, or an above-average amount of food
  • The amount of food fed to the rats was a effective predictor of life span than was Strain X or Y

Answer 1

1. Arguments could be made for both nature and nurture
   
   • Given the genetic relatedness among siblings, one could argue that there is a strong genetic component involved in bipolar disorder
   • However, given that most siblings are raised in the same family environments, there could be key shared experiences in that context that increase the likelihood of being diagnosed with bipolar disorder.
2. This would support a nature argument
   
   • If aggression levels are more similar to biological relatives compared to adopted relatives, then this would suggest a genetic underpinning.
3. This would support a nurture argument
   
   • MZ twins are genetically identical
     
     • therefore, one would argue that differences in alcoholism could be attributed to different environmental contexts in which these individuals are raised
4. This would support a nature argument
   
   • Given that both sets of twins are raised in similar environments, one would assume that the higher concordance of IQs among MZ twins would be attributable to genetics.
5. This would support a nurture argument
   
   • Amount of food available was more predictive than genetic predisposition to obesity

Question 2

Behavioral Genetics

• Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment
  
  • For every ___al, ____al, or ___al characteristic or behavior, scientists ask WHAT question?
  • What almost always the answer?

Answer 2

• For every psychological, sociological, or biological characteristic or behavior, scientists have asked the question
• “Is this primarily the result of genes (nature), or the influence of the environment (nurture)?”*
• The answer is most often (but not always)

BOTH!

Question 2

Behavioral Genetics

• Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment

Interdependence of Genes & Environment

• Scenario #2: Different Genes, Same Environment

Answer 2

Genes⇒Environment

• Suppose you have a genetic predisposition toward high IQ and your adopted brother has a predisposition toward low IQ
• You are raised in the same home and loved equally
• One would assume environment will be controlled, or the same, for both of you
  
  • However, as your genes are expressed, they impact your mother
  • When she smiles at you, you smile back
  • You talk earlier than your brother and are more interactive

Almost unavoidably, your mother will begin treating YOU differently

• While you do have the genes for higher IQ, those genes are not acting ALONGSIDE the environment
  
  • …they are actually CHANGING the environment!
• The same is true of your adopted brother
• He gets less attention and praise because he interacts less
• In this case, the influence of genes on environment makes the disparity between you and your brother greater than one would expect based on the genetic differences

Question 2

Behavioral Genetics

• EXPERIENCE-BASED (Environmental) INFLUENCES ON BEHAVIOR:
  
  • The influence of experience on behavior would include everything that is NOT ______
    
    • Give some examples

Answer 2

The influence of experience on behavior would include everything that is NOT GENETIC

• Learning
• Conditioning
• Socializing
• One’s environment, and
• any other experience you encounter in life

​…all impact your behavior

Question 2

Behavioral Genetics

• Regulatory Genes and Behavior
  
  • Define & Describe “Regulatory Genes”

Answer 2

Regulatory genes

are genes that code for a substance that regulates the transcription of ANOTHER GENE

• Includes:
  
  • up or down regulation
  • promotion
  • inhibition

Question 2

Behavioral Genetics

• Genetically-based Behavior Variation in Natural Populations
  
  • …provide evidence for the influence of genetics on behavior

Describe the following 3 observations and how they show the influence of genetics on behavior

1. Species-Specific Behaviors
2. Animal Breeding
3. Familial Concordance

Answer 2

1. Species-Specific Behaviors
   
   • Behavior observed only among members of the same species
2. Animal Breeding
   
   • Animals can be bred to exhibit target behaviors, such as:
     
     • Aggression being genetically-selected for in rodeo bulls
     • Hunting skills being genetically-selected for in certain dog breeds
3. Familial Concordance
   
   • Behaviors shown to run in families

OR

• be more frequent among children of parents with that behavioral trait

Question 3

Behavioral Genetics

• Behavior and Natural Selection:

Describe:

• Innate Behavior
• Learned Behavior
• Adaptive Value
  
  • Traits with high adaptive value are more likely to…?
    
    • Why?
• What is “Adaptive Evolution,” and what 2 things can it occur with?

Answer 3

Innate Behavior

• Behavior thought to be predominantly genetic and present regardless of environmental influences

Learned Behavior

• Behaviors thought to be predominantly environmental (i.e., learned via experience), and independent of heredity

Adaptive Value

• The degree to which a behavior INCREASES EVOLUTIONARY FITNESS
  
  • Traits with high adaptive value are more likely to be represented in future generations
    
    • Because natural selection favors the most fit individuals and behaviors, these behaviors will eventually result in a change in the gene pool—
      
      • an increase in the more adaptive trait

This is adaptive evolution and it can occur with:

• both physical traits
  
  • e.g., Darwin’s Finches and beak structure
• …and behavioral traits
  
  • e.g., Different dog breeds bred for different behaviors

Question 4

Behavioral Genetics

Nature vs. Nurture Study Methods

• Describe:
  
  • FAMILY studies
  • ADOPTION studies

Answer 4

Family Studies

• Compare frequency of behavior/condition/trait among related individuals to the frequency of that same measure among non-relatives

Adoption Studies

• Compare the behaviors/conditions/traits of an adopted child to those of its adoptive parents;
• Simultaneously compare that same child, on those same measures, to its biological parents.

Question 4

Behavioral Genetics

• Nature vs. Nurture Study Methods
  
  • For the following twin study experimental design types, identify the dependent variable, independent variable, any obvious study limitations, and—if present—the control:
    
    • Family Studies
    • Adoption Studies
    • Twin Study
      
      • MZ vs. DZ, both raised together
    • Twin Study
      
      • MZ and MZ, raised together vs. apart

Answer 4

Family Studies

Dependent variable:

• rates of neurodegenerative disease

“Independent” variable:

• degree of relatedness
  
  • this is not a true independent variable
    
    • because it cannot be actively manipulated
      
      • ∴ this research is correlational in nature (and has all the inherent problems of correlational research)

This is usually referred to as a quasi-independent variable

Think “Quasimodo”= DEFORMED

• Family studies are limited –
  
  • ​because families in which the disease occurs will be selectively recruited
    
    • ​which makes sample representativeness problematic
    • “Sampling Bias”

Adoption Studies

• Dependent variable:
  
  • IQ
• Quasi-independent variable:
  
  • adopted vs. biological
• These types of studies are difficult to do because:
  
  • there is a relatively small population to select from
  • Difficulty in attaining information about biological relatives of adopted individuals

Twin Study

MZ vs. DZ, both raised together

• Dependent variable:
  
  • aggression level
• Quasi-independent variable:
  
  • degree of relatedness (MZ vs. DZ twin)
• Potential limitations lie again in generalizability

Twin Study

MZ and MZ, raised together vs. apart

• Dependent variable:
  
  • obesity
• Quasi-independent variable:
  
  • reared together or apart
• These studies are difficult because access to these populations is very limited

Question 5

Behavioral Genetics

• Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment
  
  • Describe “Interdependence”

Answer 5

INTERDEPENDENCE

• The influence of genes and environment on biology and behavior goes well beyond the simple fact that BOTH factors influence most traits
  
  • The two influences are often interdependent—literally changing each other

Question 5

Behavioral Genetics

• Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment

Interdependence of Genes & Environment

• Scenario #1: Same Genes, Different Environment

Answer 5

Environment⇒Gene Expression

• Suppose your genes predispose you to a high IQ, but your environment includes a mother who is biased against people who “think they are smart.”
  
  • Your mother’s reinforcement can actually CHANGE the way your genes are expressed
• Suppose your identical twin is adopted by a mother with a PhD who constantly encourages learning
  
  • YOUR brain may perform neuronal pruning on underused synapses that are underused because your mom discourages learning
  • Your twin brother has those neuronal synapses strengthened because he uses them—
    
    • under the influence of an encouraging mother
  • One would expect the same “IQ genes” to produce the same neurological structures and capacity, but that is NOT the case
    
    • because environment altered gene expression

Question 5

Behavioral Genetics

Nature vs. Nurture: “The Grand Debate,” Heredity vs. Environment

• Interdependence of Genes & Environment

Scenario #4: Same Genes, Different Environment

Answer 5

Environment⇒Covalent Modification of the DNA⇒Dramatically Different Physiology

• Evidence exists for cases where the gene (i.e., DNA structure) itself is covalently altered by the environment
  
  • One study showed that increased licking behavior by a mother rat resulted in methylation of a segment of DNA (preventing transcription) that codes for a regulatory protein which upregulates transcription of a membrane receptor
  • This direct change in physiology persisted into adulthood
  • Amazingly, the methylation occurred within one week and could be reversed if the mother’s licking behavior was reversed!

Question 5

Behavioral Genetics

Nature vs. Nurture Study Methods

• Describe Twin Studies
  
  • Also, differentiate b/t the 2 types:
    
    • Dizygotic Twins (“DZ”) aka?
    • Monozygotic Twins (“MZ”) aka?

Answer 5

Twin Studies

• Compare concordance rates between monozygotic (MZ) twins raised in the same family to dizygotic (DZ) twins raised in the bfamily

OR

• Compare concordance rates for monozygotic twins raised in the same family to those raised apart

Monozygotic Twins

a.k.a., “Identical Twins”

• Genetic influence is CONTROLLED
• Studies examine twins raised in different homes–
  
  • so that environmental influence is VARIABLE

Dizygotic Twins

a.k.a., “Fraternal Twins” or NON-identical

• Genetic influence is VARIABLE
• Studies examine twins in the same home–
  
  • so that environmental influence is CONTROLLED

Question 5

Behavioral Genetics

• Nature vs. Nurture Study Methods
  
  • Suppose you are asked to design a study to investigate the degree to which Behavior X is HERITABLE
    
    • ​also–what does “heritability” refer to?
  • Rank the studies outlined above (Family, Adoption, Twin) according to their increasing ability to produce accurate results WITHOUT confounding variables
  • Discuss the individual limitations of each study for this purpose

Answer 5

“Heritability” refers to the percentage (%) of trait variability that is attributable to GENES

Twin studies

• involving DZ twins raised together compared to MZ twins raised together
  
  • would be one of the BEST TOOLS AVAILABLE to estimate a given trait’s heritability–
    
    • because it is generally assumed that the shared environments would be so similar as to be inconsequential to contributing to trait variability
      
      • ∴ less confounding variables

Family studies

• Would be another way to get at this question
• However, as one moves outside of one’s immediate family, larger variations would be expected
  
  • …in terms of environmental factors

Adoption studies

• Are also potential tools provided that:
  
  • information is available about the trait of interest from the biological parents
• If the adopted child is more similar to biological parents than to the adopted parents
  
  • then one could argue that there was substantial heritability for that trait

Question 6

Behavioral Genetics

• Regulatory Genes and Behavior
  
  • Describe how the example below shows how Regulatory Genes influence behavior

Same Genes, Different Environment

Environment ⇒Covalent Modification of the DNA⇒Dramatically Different Physiology

Evidence exists for cases where the gene (i.e., DNA structure) itself is covalently altered by the environment

One study showed that increased licking behavior by a mother rat resulted in methylation of a segment of DNA (preventing transcription) that codes for a regulatory protein which upregulates transcription of a membrane receptor

LICKING=A WAY RAT COPED WITH STRESS

This direct change in physiology persisted into adulthood

Amazingly, the methylation occurred within one week and could be reversed if the mother’s licking behavior was reversed

Answer 6

• In this case, a certain gene influenced an individual’s ability to cope with stress
• However, it wasn’t this “stress coping” gene that was regulated–
  
  • It was the regulator OF the “stress coping” gene that was “turned off”–
    
    • via methylation of the DNA sequence (gene) coding for the regulator

Under normal conditions, the regulator promotes transcription (and therefore translation) of a glucocorticoid membrane receptor

**By preventing the synthesis of the promoter**, thebehavior of the mothereffectivelyALTEREDthegenetically-determined behavior of the child (i.e., the child’s ability to cope with stress).

Question 7

The ENTIRE CNS=___+___

Answer 7

=BRAIN + SPINAL CORD

Question 9

Personality

• Other (aka Non-Freud or Jung) Personality Types:

Describe the most basic components of the personality theories of ALFRED ADLER

1. Creative Self
2. Style of life
3. Fictional Finalism
4. Inferiority Complex

Answer 9

Alfred Adler (​A Neo-Freudian)

• Adler espoused a much more OPTIMISTIC view of human nature than did Freud

As such, Adler believed that all human behavior was guided through a process of self-improvement and success

• and that each individual’s personality was forged through his/her choices
  
  • …and was often motivated by feelings of inferiority that each of us experiences in some aspect of our lives
• This is known as the concept of “Creative Self”
  
  • …​and it helps to forge a person’s “Style of Life”,
    
    • or “unconscious patterns of behavior in dealing with all aspects of life”
• Adler believed that Freud’s focus on childhood experiences and their role in establishing adult personality represented “Fictional finalism”
  
  • …because this approach ignores the active role that individuals play in determining their own personalities
• Individuals who fail to use their feelings of inferiority as motivation for self-improvement may experience an inferiority complex–
  
  • by which they feel entirely overwhelmed and powerless as a result of their shortcomings

Question 10

Theories of Personality

• Humanistic Personality Theories

Psychoanalytic vs. Humanistic Perspectives on Personality

• Think of “Psychoanalytic” as:
• Think of “Humanistic” as:

How do compare a person with their neuroses?

(aka mental illnesses)

Answer 10

THINK of Psychoanalytic as:

• Patients are “sick”, repressed, or have other troubles in need of treatment

A person is DEFINED by their neuroses

THINK of Humanistic as:

• How healthy individuals strive toward self-realization
• Has a more HOLISTIC view

A person is MORE than just the sum of their neuroses

Question 10

Theories of Personality

• Humanistic Personality Theories

Describe Max Wertheimer’s “Gestalt Therapy”

Answer 10

MAX WERTHEIMER: Gestalt Therapy

• A humanist approach to therapy emphasizing the treatment of the individual as a whole
• Rather than* reducing the person to a sum of their individual behaviors, drives, or neuroses

Question 11

Theories of Personality

• Humanistic Personality Theories

Describe Kurt Lewin’s “Field Theory”

Answer 11

KURT LEWIN: Field Theory

• Focuses on the state-of-mind of the patient as
  
  • the sum of interactions between:
    
    • their individual personality, and
    • the “total field” (environment)

Question 11

Personality Theories

• Humanistic Personality Theories

Describe Carl Rogers’ “Client-Centered Therapy” (CCT)

Answer 11

CARL ROGERS: Client-Centered Therapy (CCT)

• One of the most widely-used psychotherapeutic approaches
• In CCT, therapists should NOT direct the therapy or offer solutions

THE CLIENT DIRECTS THE DISCUSSION

• Further, the therapist must always be:
  
  • empathetic,
  • genuine and
  • show unconditional positive regard for the client

…REGARDLESS of circumstance

• Finally, Rogers emphasized calling the recipient a “client” rather than a “patient”
  
  • to avoid the concept that they are “sick” and need help
    
    • –which he viewed as judgmental

Question 12

Theories of Personality

• Humanistic Personality Theories

Describe George Kelly’s “Personal Construct Theory”

Answer 12

GEORGE KELLY: Personal Construct Theory

• Personality is composed of the various mental constructs
  
  • ​–through which each person views reality

Question 13

Theories of Personality

• Describe (in general):

Humanistic Personality Theories

• What do they say Personality consist of?
• What is Fundamental to “Humanism?”

Answer 13

Humanistic Personality Theories

• Personality consists of the conscious feelings we have for ourselves
  
  • …as we strive to reach our individual needs and goals (i.e., self-actualization)

Fundamental to humanism is the idea that people are inherently good

Question 14

Personality

• Other (aka Non-Freud or Jung) Personality Types:

Describe the most basic components of the personality theories of KAREN HORNEY

1. Neurotic Needs
2. Basic Anxiety
3. Basic Hostility

Answer 14

Karen Horney

• was another Neo-Freudian who parted with Freud’s views on a number of counts
• For one, Horney refused to accept that sexual and aggressive urges were the key factors in determining someone’s personality
• She also rejected the emphasis that Freud and his follower’s placed on the male sex organ (she was a DICK HATER)
• As such, she took a much more humanistic view of personality

One of Horney’s major contributions to psychology involved her theory of Neurosis

(Basic) HOSTILITY⇒ (Basic) ANXIETY⇒ NEUROSIS, and its accompanying “NEUTORIC NEEDS” (to cope w/ anxiety)

• According to Horney, neurosis results from basic anxiety which results from troubles in personal relationships that stem from childhood
• If a child perceives that they did not have their needs met by their parents, then they would experience basic hostility towards them
  
  • This hostility would serve as one source of the basic anxiety that they feel in other relationships
  • As people try to cope with this anxiety, they may fall into a rut in terms of their coping mechanisms of choice which could be construed as a series of neurotic needs
    
    • (e.g. the need for approval, the need for power).

Question 15

Personality

• Type A vs. Type B Personality Theory
  
  • Give 3 characteristics for Type A and Type B personalities

Answer 15

Proposed by two cardiologists, Friedman & Rosenman, as a way to predict one’s likelihood of developing coronary artery disease

• Strongly criticized because:
  
  • the subjects were all male
  • Early studies were funded by tobacco companies
    
    • …who had a strong interest in the outcome

Type A Personality (later changed to Type A Behavior Pattern)

1. Competitiveness
2. Time Urgency
3. Hostility

Type B Personality (later changed to Type B Behavior Pattern)

1. More relaxed and reflective
2. Lower anxiety levels
3. Higher imagination/creativity

Question 15

Theories of Personality

• Describe (in general) Trait Personality Theories
  
  • How do these theories differ from Psychoanalytic or Humanistic perspectives?

Answer 15

TRAIT Personality Theories:

• Personality= Σ of Traits
  
  • ​broad, relatively-stable characteristics or dispositions
• These theories are focused on unique DIFFERENCES between individuals–
  
  • whereas Psychoanalytic or Humanistic perspectives focus more on commonalities among all people
    
    • e.g., common needs, common neuroses

Doesnt give a crap about her family)

Question 20

Psychological Disorders

• Personality Disorders

Cluster C

• ​Describe:
  
  • Avoidant Personality Disorder
  • Dependent Personality Disorder

Answer 20

Avoidant Personality Disorder

THINK: Socially anxious Redditor

• Characterized by:
  
  • extreme shyness
  • sensitivity to criticism and rejection
  • low self-esteem,
  • avoidance of social situations—
    
    • including school or work
• Individuals may desire closeness with others, but have difficulty forming relationships outside of their immediate family

Question 21

Psychological Disorders

• Personality Disorders

Cluster C

• Define Obsessive-Compulsive Personality Disorder (OCPD)
• Differentiate between OCPD and OCD

Answer 21

Obsessive-Compulsive PERSONALITY Disorder (OCPD)

• Characterized by a chronic and significant preoccupation with perfection, control and order
• May include rigid behaviors, resistance to change, inflexibility, stubbornness, and a sense of helplessness in uncontrollable circumstances

Obsessive compulsive disorder (OCD) and obsessive compulsive personality disorder (OCPD) are two distinct diagnoses

• OCD involves obsessions that generate anxiety and compulsive behaviors that are engaged in an attempt to alleviate anxiety
  
  • These thoughts and behaviors are generally UNWELCOME
• The experience of an individual with OCPD is quite different in that they tend to be preoccupied with rules, regulation, and organization
  
  • They tend to DEMAND PERFECTION in all of their endeavors and are quite inflexible in their patterns of thoughts and in the way that they approach new problems

Unlike someone diagnosed with OCD, the OCPD individual views their perspective as an EFFICIENT (“GOOD”) way to deal with the challenges of life and are MUCH LESS LIKELY to seek professional help to address these issues

Psychological Disorders

• Obsessive-Compulsive Disorder (OCD)
  
  • Describe the basic diagnostic symptoms of Obsessive-Compulsive Disorder according to DSM-5
  • What is the difference between an obsession and a compulsion?

Answer 25

In order to be diagnosed with obsessive-compulsive disorder, an individual must exhibit obsessions AND/OR compulsions

• Obsessions
  
  • involve repeated occurrence of unwanted thoughts which generate significant anxiety such that the individual experiencing them will try to make these thoughts stop
• Compulsions
  
  • ​are repeated patterns of behavior or thought that the individual engages in to make obsessions go away

  • Usually during the winter

Question 28

Psychological Disorders

• Bipolar Disorder:

Provide a conceptual definition for the following terms as they relate to Bipolar Disorder:

• Manic episode
• Bipolar I
• Hypomania
• Bipolar II

Answer 28

MANIC EPISODES

• are disturbances of mood that are used to diagnose bipolar disorder
• Many individuals who are diagnosed with some sort of bipolar disorder often experience alternations between manic episodes and depressed episodes
  
  • However, depressed episodes are NOT
  • part of the diagnostic criteria

The severity of the manic episode will often dictate the specific diagnosis that is made:

• For instance, individuals with full blown manic episodes are diagnosed as BIPOLAR I
• However, if the individual experiences less intense mania, or HYPOMANIA, then they are more likely to be diagnosed as BIPOLAR II.

Question 32

Psychological Disorders

• Schizophrenia
  
  • Positive vs. Negative Symptoms of Schizophrenia

Provide a conceptual definition for the following terms related to Schizophrenia:

• Prodromal phase
• Disturbance of affect
  
  • Flat affect
  • Inappropriate affect
  • Blunting a.k.a., “Blunted affect”
• Hallucinations
  
  • are often ____ in nature

  • Delusions of grandeur
  • delusions of persecution
  • delusions of reference,
  • thought insertion,
  • thought broadcasting,
• Disorganized Behavior
• Catatonia
• Echolalia
• Echopraxia

Answer 32

Prodromal phase of schizophrenia

• is essentially EARLY onset of schizophrenia
• At this stage, mild, nonpsychotic symptoms begin to surface
  
  • As a result, the individual in the prodromal phase may begin to exhibit behavioral differences
    
    • e.g. may lose interest in things that once brought pleasure or may begin to isolate themselves from others
  • …that are a signal that something is wrong

Disturbance of affect

• Refers to the emotional irregularities that can occur in individuals who suffer from schizophrenia
• Such disturbances can manifest themselves as:
  
  • Inappropriate emotionality (“Inappropriate affect”)
  • As significant reductions in emotional response (“Blunted affect”), or
  • As a complete lack of emotional responsiveness (“Flat affect”)
• Schizophrenia is often marked by the presence of Hallucinations (often auditory in nature) and Delusions

In both instances, the schizophrenic is not in touch with reality

DELUSIONS (“Delusional thinking”)

• Often involves:
  
  • An inflated sense of self-importance or power
    
    • (“Delusions of Grandeur”)
  • A belief that others are plotting to hurt or control them
    
    • (“Delusions of Persecution”)
  • Seeing personal meaning in any variety of mundane events that occur around them
    
    • (“Delusions of Reference”)
  • Believing that others are placing thoughts in their minds
    
    • (“Thought Insertion”)
  • That others have access or can hear their thoughts
    
    • (“Thought Broadcasting”)

Aside from disordered patterns of thought, individuals diagnosed with schizophrenia often exhibit:

• Disorganized behavior
  
  • ​in which they engage in bizarre, pointless behaviors

Others may exhibit “catatonia”

• …In which they remain abnormally still for extended periods of time

In some instances the individual may automatically repeat anything that is said by others

• (“Echolalia”)

Or imitate any movements made by someone else

• (“Echopraxia”)

Question 33

Psychological Disorders

• Somatic Symptom & Related Disorders

What disorder are “Hypochondriacs” classified under?

Answer 33

NEITHER!

What was formerly known as “hypochondriasis” was separated into these new, more empirical categories in DSM-5

• Somatic Symptom Disorder and Illness Anxiety Disorder have similar symptoms that could be easily confused
  
  • SSD patients
    
    • DO have a verifiable physical symptom

“WTF is this (symptom)? OMG I’m worried nobody knows what it is!!!”

• IAD patients
  
  • have anxiety about the POSSIBILITY of having an undiagnosed illness, or worry they will develop one
  • …but have NO current symptoms

“OMG what if I’m sick?? I don’t want to get sick and die OMG!! What if I get Alzheimers or something?!”

Question 35

Psychological Disorders

• Understanding Psychological Disorders:
  
  • Compare the Biomedical & Biopsychosocial approaches

Answer 35

Biomedical Approach

• Psych disorders are caused by biological or chemical dysfunction
  
  • e.g., genetic predisposition, abnormally low hormone or neurotransmitter levels
• Treatments are primarily biochemical
  
  • ​e.g., surgery, drugs
• Considered more narrow by psychologists
• Focused more on relieving symptoms

Biopsychosocial Approach

• Psych disorders are caused by a combination of:
  
  • Biochemical Factors
    
    • e.g., genetic defect, low hormone level
  • Psychological Factors
    
    • ex: personality, unhealthy behaviors
  • Sociological Factors
    
    • ex: culture, peer pressure
• Treatments should include interventions in all three of these areas to be most effective
• Considered more broad
• Generally more “accepted” by psychologists
• Focused more on solving underlying causes and problems

Question 36

Understanding Psychological Disorders

Biomedical vs Biopsychosocial approach

Describe in detail how the following problems would be addressed using primarily a biomedical approach, and alternatively how they would be addressed using primarily a biopsychosocial approach

• Patient A:
  
  • is morbidly obese and has a history of failed dieting and weight loss attempts
• Patient B:
  
  • Suffers from severe depression after having multiple pregnancies end in miscarriage
• Patient C:
  
  • Recently survived a major cardiac arrest and underwent multiple bypass surgery
  • He has a very high blood cholesterol level

Answer 36

Patient A

• A morbidly obese individual would probably be referred for gastric bypass surgery from someone coming from a biomedical perspective
• While a healthcare provider taking a biopsychosocial approach might also recommend gastric bypass surgery, this would be done in conjunction with some sort of psychological evaluation and counseling to help the patient overcome unhealthy patterns of behavior that contributed to and maintained the morbid obesity

Patient B

• The patient might be treated with antidepressant medications and/or medications that would stabilize future pregnancies by someone coming from the biomedical perspective
• Again, these things *would be done*, but IN CONJUNCTION with counseling on the grief and loss felt by the woman in the biopsychosocial approach

Patient C

• Biomedically speaking, the patient would be treated with medications to help lower cholesterol.
• From a biopsychosocial perspective, this drug therapy would be combined with an attempt to help the patient understand and process the fear that they might feel as a result of these experiences
• In addition, they might receive counseling on how to reduce stress and live a healthier lifestyle in the future

Question 37

Psychological Disorders

• Define “Personality Disorders”

Answer 37

     • inflated sense of self
     • decreased need for sleep
     • increased talkativeness
     • racing thoughts
     • increased distractibility
     • increased psychomotor activation

     • …to prevent harm to self or others
3. These changes are NOT better explained by:
   
   • Drug use, or
   • Some other medical condition
     
     • (nothing else to blame it on)

• Dementia and language difficulties are common, but NOT ALWAYS present

Biological Correlates:

• Decreased stimulation of the motor cortex by the basal ganglia
  
  • due to a decrease in dopamine production
    
    • ​by the substantia nigra
• The basal ganglia is necessary for producing SMOOTH motor movements

Parkinson’s is often treated with L-Dopa, a precursor changed into dopamine in the brain

Question 48

• Recent research has shown that the brain of healthy individuals DOES occasionally form new neurons out of pluripotent stem cells in the CNS
  
  • cells similar to neurologically-bound fetal stem cells
• This has provided hope for treating diseases like Alzheimer’s and Parkinson’s*
• …and holds out the promise of someday being able to regrow or replace nerves damaged or malfunctioning in any NEUROGENERATIVE disease or paralysis*

• During embryological development, the neural tube is divided into the prosencephalon, mesencephalon, and rhombencephalon
  • The rhombencephalon differentiates further into the metencephalon and myelencephalon
  • The prosencephalon differentiates further into the telencephalon and the diencephalon
• Suppose that physical or chemical injury occurred to one of these embryological regions during development

In each case (metencephalon, myelencephalon, diencephalon,& telencephalon) which adult brain region and function would be lost or impaired?

Answer 67

The Metencephalon

• will serve as a precursor to the pons, cerebellum, and reticular formation
• Disruptions to these areas would impact:
  
  • sensory-motor processing and coordination
  • balance, and
  • the sleep-wake cycle

The Myelencephalon

• will give rise to the medulla oblongata
  
  • which is important for basic functions like:
    
    • respiration and
    • heart rate

The Diencephalon

• would contain structures like the hypothalamus, thalamus, and pineal gland
  
  • It also provides connections to the peripheral NS and the endocrine system
• Disruption of these systems would involve widespread effects including
  
  • sensory processing
  • regulation of peripheral NS function
  • regulation of endocrine function, and
  • homeostasis

The Telencephalon

• contains olfactory bulbs, cerebral cortex, and the basal ganglia
• Disruption to these areas would affect:
  
  • intelligence
  • language
  • motor function, and
  • sense of smell

Question 69

The Nervous System and Behavior

• The Influence of Neurotransmitters on Behavior

For each of the six neurotransmitters (ACh, Epinephrine, Norepinephrine, Dopamine, Serotonin, GABA), describe:

1. WHERE the neurotransmitter is most likely to be found and/or act
2. Its primary regulatory function(s)
3. Any correlates to disease or psychological disorders

Hints:

1. Some parts of this question will require multiple responses
   
   • For example, acetylcholine is:
     
     • located in BOTH the PNS and CNS, and
     • has multiple functions in various divisions of the nervous system
2. Low levels of some neurotransmitters are associated with multiple diseases or psychological disorders

Answer 69

ACETYLCHOLINE

• is found in both the CNS and the PNS
  
  • In the CNS, acetylcholine is involved in arousal and attention
    
    • Depletions of acetylcholine centrally is associated with the memory deficits associated with Alzheimer’s disease
  • In the PNS, acetylcholine is the primary neurotransmitter of the neuromuscular junction
    
    • ​Is also found in both the sympathetic and parasympathetic divisions of the autonomic nervous system

EPINEPHRINE (aka “adrenaline”)

• is found primarily in the PNS
• Is associated with the stress response elicited by activation of the sympathetic nervous system

NOREPINEPHRINE (aka “noradrenaline”)

• is found in both the CNS and PNS
  
  • Centrally, norepinephrine is associated with attention and emotional processing
    
    • Anxiety disorders and depression are associated with decreased norepinephrine activity
  • Peripherally, norepinephrine contributes to the stress response associated with activity of the sympathetic division of the autonomic nervous system

DOPAMINE

• is found in the CNS
• Is associated with sensorimotor integration and in reward processing
  
  • Parkinson’s disease
  • Tourette’s syndrome
  • Huntington’s chorea, and
  • Schizophrenia

…are all associated with abnormal activity in the dopamine system

SEROTONIN

• is found in the CNS
• Is associated with homeostatic regulation of sleep and appetite
• Serotonin is also involved in regulation of mood
• Lowered serotonin levels are associated with depression

Gamma-aminobutyric acid (GABA)

• is the chief inhibitory neurotransmitter of the CNS

Question 70

Question 73

The Nervous System and Behavior

• The Brain: Structure and Region-Based Functionality

Methods Used to Study the Brain

• Name 3 INVASIVE and 3 NON-invasive methods for studying the brain
• “Invasive”= body is “invaded,” or cut open*

Answer 73

NON-INVASIVE:

1. Electroencephalography (EEG)
2. Transcranial Direct Current Stimulation (TDCS)
3. Regional Cerebral Blood Flow (rCBF)

INVASIVE:

1. Direct Electrode Stimulation
   
   1. (open cranium, during brain surgery)
2. Human Brain Injury Case Studies
3. Lab Animal Extirpation

Question 74

The Nervous System and Behavior

• The Brain: Structure and Region-Based Functionality

Lateralization of Cortical Functions

• Provide a conceptual definition for each of the following terms:
  
  • Contralateral
  • Ipsilateral
  • Left hemisphere
  • Right hemisphere
  • Dominant hemisphere
  • Non-dominant hemisphere

Answer 74

Contralateral

• literally means “opposite side”
  
  • In this context, contralateral refers to the idea that sensory and motor functions of the left side of the body are processed in the right side of the brain

Ipsilateral

• would refer to the same side
  
  • For example, a tumor involving the right side of the brain may affect vision ipsilaterally–
    
    • that is, in the right eye

The Dominant hemisphere

• is the side of the brain that is used in controlling the preferred arm or leg
• Most individuals are right handed
  
  • therefore, the dominant hemisphere for most people is the left hemisphere

Left hemisphere

• is also thought to be more important for linguistic processing in most individuals

Right hemisphere

• is considered the non-dominant hemisphere for most individuals, but that is not to say that the right hemisphere is not important for a variety of functions
  
  • For instance, the right hemisphere is thought to be much more important in visuospatial processing and in the processing of certain kinds of emotional information

Question 76

The Brain: Structure and Region-Based Functionality

• Lateralization of Cortical Functions
• Suppose a person sustains major injury to the dominant hemisphere, but NOT to the non-dominant hemisphere*

What losses of function are most likely,

and to WHICH side of the body?

What if the injury IS to the non-dominant hemisphere?

Answer 76

Damage to the dominant hemisphere would likely result in:

• LANGUAGE difficulties
• loss of CONTROL of MOVEMENT

…..to the RIGHT side of the body

Assuming that for most people the

left hemisphere is dominant

Damage to the non-dominant hemisphere would lose:

• Some control of movement
  
  • ​in the LEFT side of the body
• Might also result in:
  
  • difficulties in spatial navigation
  • emotional processing

Question 77

The Nervous System and Behavior

• The Brain: Structure and Region-Based Functionality
  
  • Functional Regions of the CNS

Inferior Neural Tube

• Gives rise to what structure?
  
  • What are the functions of this structure?

Answer 77

Inferior Neural Tube gives rise to the SPINAL CORD

• Spinal Cord:
  
  • Reflexes
  • Bundled tracts to and from peripheral NS

Question 78

The Nervous System and Behavior

• The Brain: Structure and Region-Based Functionality

Lateralization of Cortical Functions

• Predict the likely repercussions of a rare congenital defect resulting in a person with a NORMALLY functioning brain, but NO corpus callosum?
  
  • Hint: The corpus callosum is a bundle of nerves that connects the left & right hemispheres of the brain

Answer 78

• Individuals who suffer from congenital agenesis of the corpus callosum have difficulty transferring information between the two hemispheres
  
  • As a result, they experience difficulties in problem solving
  • In addition, they also exhibit:
    
    • Impaired social behavior
    • a variety of sensory impairments, and
    • Problems in:
      
      • muscle tone
      • motor behavior

Question 79

Theories of Personality

• Jung vs. Freud:
  
  • “LIBIDO”

Answer 79

Freud

• Driving psychic energy of the ID
  
  • Is primarily sexual

Jung

• Generalized psychic energy
  
  • Not exclusively sexual

Question 80

Theories of Personality

• Jung vs. Freud:
  
  • the “UNCONSCIOUS”

Answer 80

Freud

• “Storage place” of unacceptable, repressed desires
  
  • Parts of the EGO and SUPEREGO are unconscious
  • As is ALL of the ID

Jung

• Storage place of repressed memories
  
  • ​both good and bad
• Ego is NOT part of the unconscious mind
  
  • t is 100% conscious
• Two Subdivisions of the unconscious:
  
  • Personal unconscious
  • Collective unconscious

Question 81

Theories of Personality

• Jung’s Archetypes

Provide a conceptual definition and real-life example for each of Jung’s archetypes (4)

• Hint: “S.A.P.S.”
• Which of these archetypes is similar to Freud’s ID?

Answer 81

“Archetypes” are UNIVERSAL mental images or concepts within the collective unconscious

…that influence behavior and thought

THINK: Superman= “Hero” archetype

• Jung identified several different archetypes:

1. The Self
2. The Anima/Animus
3. The Persona
4. The Shadow
   
   • similar to Freud’s Id

The Self

• is an archetype in which the entire mind (both conscious and unconscious) is unified
• Examples:
  
  • Circles, squares, trees and holy figures all serve as representations of the self

The Anima

• represents the female in a male
• Animus represents the male in a female

Examples:

• Anima
  
  • The image of the Virgin Mary
• Animus
  
  • Jesus Christ

The Persona

• is how one presents themselves to the world
• Example:
  
  • is often represented by the symbol of a MASK

The Shadow

• is an archetype that embodies uncertainty and danger
  
  • ​…and is often alluring in some way
• Example:
  
  • Any dark figure that appears in a dream
    
    • e.g. the devil

Question 82

Theories of Personality

• Jung’s Archetypes are ____s and ____s that have what across what?
  
  • Where do they originate from?

How do Jung’s Archetypes relate to Freud’s theory of personality?

Answer 82

JUNG’S ARCHETYPES:

…are Images and thoughts that have UNIVERSAL MEANING across cultures

• Perhaps arising from our shared ancestral past

UNIQUE to Jung, NOTHING comparable from Freud

Question 83

Theories of Personality

• Sigmund Freud’s Psychoanalytic Personality Theory

Describe “ID”

• What is the only realm it operates in?
• What behaviors is it responsible for?
• Is it present at birth?
• Is the _______ component of “Personality”
• Involves what 3 concepts?

Answer 83

100% UNCONSCIOUS

• Responsible for all instinctive and primitive behaviors.
• The only one of the three components present from birth
• Is the Primary (or most important) component of personality;
  
  • the “source of all psychic energy”
• Involves the concepts of:
  
  • Primary Process
  • Wish Fulfillment
  • Libido

Question 84

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

ID

• Define Primary Process and Wish Fulfillment as they relate to Freud’s theory of personality

Answer 84

The id seeks to have all its needs GRATIFIED as soon as possible

The Primary Process​​

• Would be a way that the id deal with the frustration of delayed gratification
  
  • …because it serves as a memory of the object needed for gratification
    
    • …until the gratification could ACTUALLY be realized
    • EX: No BJ’s til marriage, so you think about BJ’s until your wedding day
• As the ego and superego come online and actively suppress some of the id’s demands, a person might experience dreams that serve as “wish-fulfillment”
  
  • ​Denied its demands, the id seeks to satisfy them through unconscious thought process
  • Ex: Wet Dreams

Question 86

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

Describe the “EGO”

• What realms does it operate in?
• How does it relate to the Id and Superego?
• Is it present at birth?
• What 2 concepts does it include?

Answer 86

EGO

Operates in the:

Conscious, PRE-conscious and UNCONSCIOUS realms

• Responsible for helping the desires of the Id to be realized in a way acceptable in real-life scenarios
• Also helps balance the “perfectionist tendencies” of the Superego
• Is NOT present at birth
  
  • develops from the Id

Includes the concepts of:

1. Secondary Process
2. The Reality Principle

Question 87

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe the Thematic Apperception Test​

Answer 87

THEMATIC APPERCEPTION TEST

• Respondents are provided a series of ambiguous pictures
  
  • …and are asked to come up with a dramatic story about the picture

Question 88

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Projection”
  
  • Give an example

Answer 88

PROJECTION

• involves attributing YOUR OWN unwelcome thoughts/feelings to someone else

Example:

• “WHY ARE YOU ANGRY?!?!”
• A teacher who dislikes a student may think that she likes the student, but insists that the student doesn’t like HER
• A man is angry with his wife because he believes that she is bored in their relationship, when in fact HE is bored with their relationship

Question 90

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Regression”
  
  • Give an example

Answer 90

• Regression involves reverting to patterns of behavior that were used at earlier stages of life–
  
  • in order to deal with stress

Example:

Adults throwing temper tantrums after being denied a job promotion or a teenager sucking his/her thumb after being dumped by their significant other would be examples of regression as an ego defense mechanism

Question 91

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe (in General), the point of these tests:
  
  • Rorschach Inkblot Test
  • Sentence Completion Test
  • Thematic Apperception Test
  • Word Association Test
• What Defense Mechanism is most applicable to these tests?

Answer 91

All of these tests are considered projective tests

• In each situation, it is assumed that the task at hand (e.g. interpreting an ambiguous picture) would allow a clinician to gain invaluable insight into the test taker’s unconscious motives and desires
• Although any number of ego defense mechanisms might be associated, REPRESSION is probably the one that people using these approaches are trying to overcome

Question 92

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Displacement”
  
  • Give an example

Answer 92

DISPLACEMENT

• involves diverting unacceptable feelings onto someone or something *other than their source*
  
  • usually diverted onto something/someone that is less threatening than the source

Example:

• A child who is angry at her parents for disciplining her may bite her little sister
• A man who was just fired by his boss may come home to start a fight with his neighbor

Question 93

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

SUPEREGO

• Provide conceptual definitions for Conscience and Ego Ideal as they relate to Freud’s theory of personality

Answer 93

According to Freud, the SUPEREGO is comprised of both conscience and the ego ideal

• The Ego Ideal sets lofty standards for the EGO to conform with
  
  • In other words, the ego ideal serves as a model for what a person should and wants to be
• ​The Conscience, on the other hand, serves as a system of rules and admonishments for “bad behavior”
  
  • “Dang man, you shouldn’t have stolen that lollipop from the candy store”
• The Conscience pushes us towards our “Ego Ideal”

Question 94

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Sublimation”
  
  • Give an example

Answer 94

SUBLIMATION

THINK: Wounded Warrior Project ​

• (Dad dies=BAD, but leads to POSITIVE outcome)*
• involves channeling unacceptable (“negative”) thoughts or urges into something that is more acceptable

Examples:

• Sublimation might be used by artists who use some personal tragedy (BAD) to energize them to create a new work of art (Good!)
• People may also use humor as a way to channel their unacceptable thoughts (BAD) into a lighthearted joke (Good!)

Question 96

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe the Word Association Test

Answer 96

WORD ASSOCIATION TEST

• Participants are provided a word and asked to provide a word that they associate with it

Examples:

• “Beer”
  
  • “Pong”
• “Dog”
  
  • “pound”

Question 98

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Denial”
  
  • Give an example

Answer 98

DENIAL

• is an inability to accept some reality
• In situations in which individuals deny something despite the fact that there is an abundance of evidence to suggest that it IS true or IS occurring, we might say that individual is “in denial.”

Example:

• A student who has NO mathematical chance of passing a course, yet studying furiously for a final exam could be described as using denial to protect themselves from the reality of a poor course grade
• Alternatively, a woman who refuses to recognize that her husband is having an affair despite clear evidence to the contrary would also be using denial as an ego defense mechanism

Question 99

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe the Sentence Completion Test

Answer 99

SENTENCE COMPLETION TEST

• Respondents are provided with beginnings of sentences and are asked to complete the sentence

….in some personally meaningful way

​

7. Gender-based differences in aggression
8. Social learning theory
9. The influence of genes on behavior

Answer 101

Provides support for:

1. Social cognitive theory
2. Learning
3. Modeling
4. Gender-based differences in aggression
5. Social learning theory

Question 102

Theories of Personality

• Behavioral Personality Theory

B.F. SKINNER

• What leads to behavior (according to Behaviorists)?
• How should you respond to negative aspects of personality or other neuroses?
• Define a “Token Economy”

Answer 102

Environment (reinforcement) ⇒ Behavior

Therapy for negative aspects of personality or any other neuroses should focus on operant conditioning–

• to reinforce more desirable behaviors
  
  • rather than focusing on some “underlying cause”
    
    • ​as would be suggested by the humanists or psychoanalysts

Token Economy

• Positive behavior is reinforced with tokens
  
  • …that can be exchanged later for:
    
    • Prizes
    • Treats, or
    • Other reinforcers

Question 103

Theories of Personality

Social Cognitive Personality Theories:

• Who was the first person to name/describe this theory?
• These theories say personality is the result of what 4 things?
• What 4 UNIQUE aspects set it apart from other perspectives? (Such as Behaviorism or Humanism)

Answer 103

Social Cognitive Personality Theories:

First named by Alfred Bandura​​​

• Personality is the result of:
  
  1. Observational learning
  2. Self-efficacy
  3. Situational influences
  4. Cognitive processes

UNIQUE ASPECTS: (Relative to other perspectives such as Behaviorism or Humanism)

1. People learn from observing and modeling others:
   
   • NOT only personal experiences or conditioning
     
     • Example of this: Bobo Doll Experiment
2. People do NOT always apply what they have learned
   
   • perceived and actual consequences influence individual choices
3. People are most likely to model the behavior of someone with whom they identify closely
4. Self-Efficacy directly impacts learning
   
   • A person’s belief in their ability to learn and implement new behaviors is closely associated with their ability to do so

Question 105

Theories of Personality

• PSYCHOANALYTIC Personality Theories:
  
  • …say that personality is mostly a function of _____, ________, __________ influences.
  • Include the theories of _____ and ____.

Answer 105

Psychoanalytic Personality Theories

• Personality is mostly a function of underlying, internal, unconscious influences
• The theories of Freud and Jung

Question 106

Theories of Personality

• Trait Personality Theories

Compare Type vs. Trait Theories

Answer 106

TYPE THEORIST VIEW

• Personality characteristics exist as discrete, fixed categories
• Most people will fit into one category or another
  
  • e.g., Introverts and extroverts are two types of people
• A single, or small set of traits defines personality type

TRAIT THEORIST VIEW

• Personality characteristics are part of a larger continuum of personality
  
  • e.g., Introversion and extroversion are traits describing ones position along a continuum
    
    • Individuals can be at either end, or anywhere in the middle
• Personality is a combination of this and many other traits along many other continuums

Question 108

Theories of Personality

• Jung’s Dichotomies: The first example of _______ _____s
  
  • Name the 3 types (“___ vs ___”)
• ​How do we combine these dichotomies to give “Jung’s Eight Cognitive Processes?”

Answer 108

Jung’s Dichotomies: The first example of Personality Types

1. Extroverted vs. Introverted
2. Sensing vs. Intuiting
3. Thinking vs. Feeling

Combining Extroverted or Introverted with each of the two remaining dichotomies gives eight (8) personality types often called “Jung’s Eight Cognitive Processes”

Question 110

Theories of Personality

• Jung’s Theory of Personality
  
  • Provide a conceptual definition for the Personal unconscious and the Collective unconscious as they relate to Jung’s theory of personality
  • Compare & Contrast the two

Answer 110

The Personal unconscious are the parts of our minds that we are not consciously aware of, but do affect our behavior

• …and can be revealed to us in our dreams
  
  • In this way, Jung’s view of the “personal unconscious” was very similar to Freud’s ideas about the “unconscious mind”
• The personal unconscious is what allows us to be creative and original in our thoughts

The Collective unconscious is the portion of the unconscious mind that is inherited and contains universal themes through all of our lives

• The collective unconscious represents a virtual repository of all of human history and experience inside each of us

Question 111

Theories of Personality

• Jung vs. Freud:
  
  • Causes of BEHAVIOR

Answer 111

Freud

• Caused by repressed desires from childhood
  
  • “Penis Envy” leads to female sexuality and gender identity (riiiiiiiiiiiiight…..)

Jung

• Caused by:
  
  1. Past experiences
     
     1. ​from childhood or adulthood
  2. Future aspirations

Question 112

Theories of Personality

Answer 112

thinking, feeling & behaving

Question 113

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

EGO

• Provide conceptual definitions for the Secondary Process and the Reality Principle as they relate to Freud’s theory of personality

Answer 113

• The Secondary Process is the EGO’s attempt to satisfy the demands that are represented by the Primary Process
• Because the ID’s demands would often be inappropriate, the ego operates on the Reality Principle
  
  • …to delay the id’s gratification until a more appropriate time

Question 114

Theories of Personality

• Sigmund Freud’s Psychoanalytic Personality Theory

ID

• Describe what the “Libido” is

Answer 114

Libido

The “psychic energy” created by the survival and sexual instincts

It is part of the Id

Was considered by Freud to be the driving influence of ALL behavior

Question 115

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Reaction formation”
  
  • Give an example

Answer 115

Reaction formation

• involves behaving in ways that are in direct contradiction to one’s TRUE feelings

Example:

• I feel like shit, but I’m bubbly and “happy” all day long
• A gay politician who actively pursues legislation to limit the rights of homosexuals or a teacher who resents a student…
  
  • yet bends over backwards to provide an unfair advantage to that student

would be using “reaction formation” as an ego defense mechanism

Question 116

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Repression”
  
  • Give an example

Answer 116

REPRESSION

• is an ego defense mechanism by which information is unconsciously pushed out of conscious awareness
• While the individual may have no conscious awareness of the repressed memory, that memory will still affect conscious behavior

Examples:

• Sexual frustration leads to porn addiction
• An individual who was sexually abused as a child may report no memory of the abuse, yet they have difficulty in forming intimate relationships as an adult
• Another example of repression might involve someone who nearly died in a car accident not remembering the incident itself, but always experiencing high levels of anxiety when driving in the future

Question 117

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe “Rationalization”
  
  • Give an example

Answer 117

RATIONALIZATION

• involves creating excuses
  
  • ​…to justify something that is UNACCEPTABLE

Example:

• A student who fails a class may claim that the class instructor was impossible to understand
• A woman who was just dumped by the man of her dreams may claim that she was never really into him to begin with

Question 118

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

Describe the “SUPEREGO”

• What realms does it operate in?
• What is it responsible for?
• Often called the “___________” portion of Freud’s theory
• How does the SUPEREGO affect the ID and EGO?
• Is it present at birth?
• What are its two components?

Answer 118

SUPEREGO

Operates in the conscious, PRE-conscious and UNCONSCIOUS realms

• Responsible for JUDGING action
  
  • …based on internalized moral standards
    
    • obtained from parents and society
• Often called the “perfectionist” portion of Freud’s personality theory

FURTHER SUPPRESSES IMPULSES of the ID

• …and influences the EGO to be more IDEALISTIC than REALISTIC
• Develops around age five

Two Components:

1. the “conscience”
2. the “ego ideal”

Question 119

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Describe the Rorschach Inkblot Test

Answer 119

Rorschach inkblot test

• involves presentation of a series of inkblots to a test taker who is asked to describe what they see

The idea is that in interpreting an ambiguous image, the clinician will gain invaluable insight into the test taker’s unconscious motives and desires

• Ex: Someone who is sexually repressed may see more sexualized images in the inkblot than others

Question 120

Theories of Personality

• Jung vs. Freud:
  
  • “EGO”

Answer 120

Freud

• Conscious, preconscious, AND unconscious.

Jung

• Conscious mind ONLY

Question 121

Theories of Personality

• Sigmund Frued’s Psychoanalytic Personality Theory

DEFENSE MECHANISMS

• Define “Defense Mechanisms”
• Name the 8 defense mechanisms to be familiar with for the MCAT

Answer 121

Freud theorized that as the EGO attempts to resolve anxiety between the ID (instinctual) and the SUPEREGO (Idealistic)

….it resorts to unconscious falsifications or distortions called “defense mechanisms”

1. Repression
2. Regression
3. Reaction Formation
4. Denial
5. Projection
6. Displacement
7. Rationalization
8. Sublimation

Question 122

Theories of Personality

• Social Cognitive Personality Theories:
  
  • Alfred Bandura

Describe the Bobo Doll Experiment

• What were the 2 results of this experiment?

Answer 122

Bobo Doll Experiment

• Famous experiment in which Bandura exposed children to adults modeling aggressive and non-aggressive behavior
• The aggressive adult models repeatedly punched, hit, kicked, and spoke violently to an inflatable “Bobo Doll.”
• The non-aggressive models played quietly with non-aggressive toys
• A control group was included with no models
• Children were allowed to play in a similar room with the same toys after watching the models
• Those exposed to the aggressive models mimicked the violent behavior toward the Bobo doll–
• While those exposed to the non-aggressive model did not

RESULTS:

• Boys were more aggressive than girls
• Overall, children were more likely to model the behavior of a same-sex model
  
  • Girls were more likely to model the aggressive language they had seen
  • Boys were more likely to model the physical violence

Question 123

Theories of Personality

• Social Cognitive Personality Theories:
  
  • Alfred Bandura
• Define:
  
  • “Reciprocal Determinism”
  • “Locus of Control”
    
    • ​ (Internal & External)

Answer 123

Reciprocal Determinism

• An individual, their behavior, AND their environment

​…affect one another

• ….Rather than the environment exclusively influencing behavior

This suggests that individuals can mold the environment that influences their development

Question 129

Theories of Personality

• Situational Personality Theory

For each theorist, state whether they would be most likely to agree or to disagree with the SITUATIONAL approach to explaining behavior and why:

• Sigmund Freud
• Carl Jung
• Gordon Allport
• Albert Bandura (& other social cognitive-theorists)
• B.F. Skinner

Answer 129

Sigmund Freud

• Believed that conscious behavior was largely driven by the conflicts that existed between the various components of the unconscious mind and the ego
• Freud would have expected the situation to have power (since the ego deals in reality), but the effect of the situation on any given behavior was certainly NOT a primary focus of Freud’s theories

Carl Jung

• Jung’s focus on the power of the situation is reflected in the archetype of the persona
• Jung believed that we often put on a good face for the world to see, yet that may or may not be reflective of the true self

Gordon Allport

• Allows for the situation to affect behavior in his concept of secondary traits
  
  • By definition, these are patterns of behavior that may only be observed in a given situation or context

Albert Bandura (and other social-cognitive theorists)

• would have strongly adhered to the idea that the situation is a powerful influence in determining one’s behavior

B.F. Skinner

• would argue that the situation is paramount to determining one’s behavior
  
  • because the given situation would determine which behaviors might be reinforced and/or punished
