Midterm 1 Flashcards
Deviance
Behaving differently, behaviours straying from societal norms or standards
Abnormal
Those having abilities that differ from the general public
Goodness of it
Understanding behaviour within a specific context, a behaviour can be problematic or not problematic depending on the environment in which it occurs
Culture
Shared patterns and lifestyle that differentiate from one group of people from another
Culture-bound syndrome
Originally described abnormal behaviours that were specific to a particular location or group, some of these patterns are now recognized to extend across ethnic groups or areas
Eccentric Behaviour
May violate societal norms, but it is not considered abnormal because it is not always negative or harmful to others (ex. millionaire leaving estate to his dog)
Behaving dangerously that -
May result from intense emotional state or signal of a psychological disorder, but alone is not necessary or sufficient (skydiving is dangerous but is not a sign of abnormal behaviour)
Behaving dysfunctional -
Behaviour that interferes with normal daily routines and / or causes significant distress, frequency of behaviours can cause distress and dysfunction
Abnormal behaviour
Behaviour that is inconsistent with the individual’s developmental, cultural and societal norms and creates emotional distress or interferes with daily functioning

1 in 3
How many Canadians meet the criteria for a substance use disorder?
6 million (20%)
How many Canadians meet the criteria for a mood disorder?
3.5 million (13%)
Prevalence and sex for mood disorders
More common among women
Prevalence and sex for substance use disorders
More common among men
Mood disorders and substance use disorders prevalence highest among people aged
15-24 years
By age 16, 1 in ___ children and adolescents have suffered from a psychological disorder
1 in 3
Categorical approach to abnormal behaviour
Do you meet the criteria or not? Either have it or you don’t. Problem is symptoms rarely fall neatly into just one category and may not appear sufficient in severity to determine that they represent a psychological disorder
Dimensional approach to abnormal behaviour
Abnormal behaviour is on a continuum and constantly changes in severity over time. Recognizes that abnormal behaviour varies
Developmental trajectory
Symptoms vary by age - adolescent vs. child has a different way of interpreting things thinking
Example of developmental trajectory
Generalized anxiety disorder is more seen in adults because it requires the ability to understand the concept of “future” which is a cognitive skill that usually emerges around age 12
Socioeconomic status and the development of psychological disorders
Study has shown that all SES groups developed disorders at the same rate, but once the child had the disorder, children from lower SES were less likely to overcome or recover from the disorder
Downward drift
The idea that the impairment that results from a psychological disorder (inability to sleep, addiction to alcohol) leads to job loss or limited educational achievement (anxiety causing someone to skip classes an drop out)
The rate of psychological disorders ___ as boys enter __ years
Decrease as boys enters teen years
Te rate of psychological disorders ___ as girls enter ___
Increase as girls enter adolescence
Ancient cultures in Egypt on abnormal behaviour
Believed spirits controlled someone’s behaviour
Ancient treatment of mental disorders (ancient Egypt)
Used Trephination - created a hole in the skull to release the evil spirits or maybe to just fix wounds
Cause of mental illnesses according to classic Greek and Roman views
Mental illness considered result from traumatic experience of imbalance in fluids found within the body, these fluids were called humours
Hippocrates
(460-377 BC) father of medicine - produced diagnostic classification system and a model to explain abnormal behaviour. First to identify symptoms associated with schizophrenia, somatoform disorder and mood disorders
Four symptoms Hippocrates identified
Hallucinations, delusions, melancholia and hysteria
Hallucinations
Hearing or seeing things not evident to others
Delusions
Beliefs with no basis in reality
Melancholia
Severe sadness
Hysteria
Blindness or paralysis with no organic cause
Hysteria is now called
Conversion disorder
Hysteria used to be thought ..
To be only in women - empty uterus wandering through the body searching for conception, external symptoms = where the uterus was lodged internally
What are four humours?
Blood, black bile, yellow bile and phlegm
What does blood represent?
Courageous and hopeful outlook on life
What does phlegm represent?
Calm and emotional attitude
What does yellow bile represent?
Mania
What does black bile represent?
Melancholia
Hippocrates’ views on treatment of mental illness
Advocated the removal of patients from their families as treatment - foreshadowing the practice of humane treatment and institutionalization
Galen’s contribution
Attributed hysteria to a psychological cause, believing it to be a symptom of unhappiness in women who had lost interest and an enjoyment of sex. Saw people with delusions
Middle ages through the renaissance - perspective on mental illness
Influence of the Roman Catholic Church, abnormal behaviour was seen as the work of the devil (demons). Witchcraft also explained abnormal behaviour - mass hysteria (caused by spirits)
Tarantism
During the middle ages there was a belief that the bite of a wolf spider (tarantula) would cause death unless a person engaged in joyous, frenetic dancing. This was fuelled by mass hysteria, as this bite as completely harmless
Lycanthropy
During the middle ages there was a belief that people were possessed by wolves, also driven by mass hysteria
Scientific basis for mass hysteria
Emotional contagion - automatic mimicry and synchronization of expressions, vocalizations, postures and movements of one person by another
Enlightenment by Johann Weyer and Paracelsus on treatment of mental illness
Refuted idea that abnormal behaviours were linked to demonic possession, believed there could be psychological origin to some physical illnesses. During the middle ages
Where were the people with mental disorders placed in the middle ages?
Housed in asylums - often called madhouses, treatment consisted of confinement (chains, shackles, isolation in dark cells), torturous practices (ice-cold baths, spinning in chairs, severely restrictive diets) and medical treatments (emetics, purgatives and bloodletting)
19th Century’s views on mental illnesses
Removed patients from warehouse asylums into specialized facilities devoted to the care and treatment of the mentally ill. More advocation for more humane, moral treatment. Us of respect, kindness, religion and vocation
Key founders of new outlook on mental illness in the 19th century
Pinel, Tuke, Rush, Diz, Kraepelin
Kraepelin
Etiology - cause of mental illness and Prognosis - development of the illness
Pinel advocated for …
Physicians listening to the patient and observing their behaviour
Mesmer
Demonstrated power of placebo effect
Perspective change within the 19th century on development / cause of mental illnesses
Discovery that a physical disease could cause a psychological disorder was significant (syphilis led to general paresis - physical paralysis and mental illness)
First asylum in what is now North America
Hotel Dieu in Quebec in 1639
Conversion asylums in the 1800s
Many jails and military barracks converted into asylums
Homewood retreat in Guelph
Received moral treatment, catered to the wealthy, wanted routine, activities, healthy diet, exercise (paying for treatment). Privately funded so residents had control over interventions
Biological scarring
Years of living with a disorder causes changes in the brain
Behavioural models, behavioural genetics
Brain malfunctioning or structural abnormalities can exist from psychological disorders (ex. frontal lobe of schizophrenics is less dense than normal)
Viral infection theory
A fetus is exposed to toxins or a virus in prenatal stage, or shortly after birth (may take several pathways to produce disorder)
Freud
Found of psychoanalysis, believed roots of abnormal behaviour were established in the first five years of life (unconscious memory). All behaviour originated in the unconscious motivations
Freud’s three regions of the brain
Id - basic instinctual drives, source of psychic energy (libido), pleasure seeking
Ego - develops when id comes in contact with reality
Superego - imposes moral restraint on the id’s impulses (especially sexual and aggressive)
Defence mechanisms
The mind’s negative or distressing thoughts and feelings are disguised to emerge to consciousness in a more acceptable form
Psychosexual stages of development
Oral, anal, phallic (sexual fantasies about parents), latency and genital phases
Which psychosexual stages of development play a more limited role in abnormal behaviour?
Latency phase and genital phase
Fixation in psychosexual development
Individuals become fixated (stalled) at a stage of psychosexual development, leaving a psychological mark on the unconscious
Treatment of psychoanalysis
Dream analysis, interpretation, free association, insight and catharsis (release of emotion)
Denial
Dealing with an anxiety-provoking stimulus by acting as if it doesn’t exist
Displacement
Taking out impulses on a less-threatening target
Intellectualization
Avoiding unacceptable emotions by focusing on the intellectual aspects of an event
Projection
Attributing your own unacceptable impulses to someone else
Rationalization
Supplying a plausible but incorrect explanation for a behaviour rather than the real reason
Reaction formation
Taking the opposite belief because the true belief causes anxiety
Regression
Under threat, returning to a previous stage of development
Repression
Burying unwanted thoughts out of conscious thought
Carl Jung
Analytic therapy, believed behavioural motivators are psychological and spiritual (not sexual) and that future goals rather than past events motivate behaviours
Alfred Adler
Individual psychology (birth order, sibling rivalry, inferiority complex)
Ego psychology
Increased focus on conscious motivations and healthy forms of human functioning
Object relations theory
Addresses people’s emotional relations with important objects, emphasizes people’s basic drive for social interactions and that motivations for social contact are more than simply to satisfy sexual and aggressive instincts
Behaviourism
All behaviour (normal or abnormal) is to be learned as a result of experiences of interactions with the environment (importance of external events)
We learn both adaptive and manipulative behaviours as a ..
Source of coping
Pavlov’s dogs and classical conditioning
UCS (meat) –> UCR (salivation), neutral stimulus of the bell paired with UCS –> CS –> CR
Watson
All behaviour is learned (little Albert and little Peter), observable behaviours
Little Albert
Paired a white rabbit with a loud noise, eventually paired fear with rabbit, eventually showed rabbit without the noise and elicited fear response
Wolpe
Demonstrated that classical conditioning could be used in the development of anxiety and to eliminate fear. Used a hierarchy of events to eliminate anxiety and taught patients how to relax
Wolpe based his theories on ..
Reciprocal inhibition
Example of hierarchy of events to eliminate anxiety by Wolpe
Someone who fears flying would divide up the task into small, doable tasks - first go to the airport, then sit in the boarding area, then go onto the plane, then take off (deal with the small things first)
Vicarious conditioning
Learning by observing another’s behaviour, then incorporating that into own way of behaving. No trial learning - the person does not need to actually do the behaviour in order to learn it (watching a model, observation)
Operant Conditioning
Reinforcement (positive and negative) increases behaviour and punishment (positive and negative) decreases behaviour
Operant conditioning - primary reinforcers
Those that have their own intrinsic value (satisfy basic need - food, water or even attention)
Operant conditioning - secondary reinforcers
Those that have gained value to the person because they become associated with primary reinforcers (money)
Operant conditioning - shaping
Closer steps or successive approximations to a final goal are rewarded (teaching dolphin to do long tricks for a show). Start with rewarding small behaviour and then gradually expect and therefore reward for larger behaviour
Biological
Field of behavioural genetics emerged with works by Galton
Biological field suggests potential relationship between
Viral infection and the onset of psychological disorders - virus may act directly by infecting the CNS or virus may act indirectly by changing the immune system of the mother of the fetus thereby making one or both more susceptible to other biological or environmental factors
Psychological approaches
Emphasizes how environmental factors (family and cultural factors) may influence the development and maintenance of abnormal behaviour
Cognitive
Proposes that abnormal behaviours is a result of distorted cognitive (mental) processes, not internal forces or external events. The way we perceive or think about the events we experience shapes who we are
Aaron Beck
Cognitive perspective. 3 distorted views of depression (the negative cognitive triad) - negative view of self, world and future
Negative assumptions often called
Cognitive distortions
Treatment for cognitive
Change these distorted thoughts using behavioural experiments and talk therapy
Example of all-or-nothing thinking
If I don’t go to an Ivy League school, I’ll be a bum
Example of overgeneralizing
Everything I do is wrong
Example of mental filtering
The instructor said the paper was good but criticized an example of page 6, therefore he really hated the paper.
Example of disqualifying the positive
Sure I got an A, but that was pure luck. I’m not that smart
Example of jumping to conclusions
The bank teller barely looked at me, she really hates me
Example of magnifying or minimizing
I mispronounced that word in my speech, I really screwed up OR I can dance well, but that’s not really important, being smart is important and I’m not smart
Example of catastrophizing
I failed the quiz. I’ll never graduate from college
Example of reasoning emotionally
I feel hopeless, so this situation must be hopeless
Example of making “should” statements
I should get an A in this class even though it is really hard
Example of mislabeling
I failed this quiz. I’m a complete and total idiot
Example of personalizing
We did not get that big account at work. It’s all my fault
Humanistic
Based on phenomenology - a person’s subjective perception of the world is more important than the actual world. Humans are good and are motivated to self-actualize (develop to their full potential)
Humanistic approach on abnormal behaviour
Occurs when there is a failure in the process of self-actualization
Carl Rogers
Abnormal behaviour originates when one’s self image and actual self are incongruent, limits ability to achieve’s one full potential, the larger the discrepancy, the motion emotional and real-world problems the person experiences
Client centered therapy
Part of cognitive approach - release the individual’s existing capacity to self-actualize through interactions with the therapist. Focuses on genuineness, epithetic and understanding (trying to understand how the client sees themselves), unconditional positive regard
Sociocultural models
Abnormal behaviour must be understood within the context of social and cultural forces such as gender roles, social class, interpersonal resources and ethnicity. Abnormal behaviour reflects the social and cultural environment in which a person lives
Sociocultural models - boys
Tend to be discouraged from showing emotion because it shows weakness (less likely to admit to having a phobia, seek help)
Sociocultural models - girls
Girls are more likely to develop eating disorders from expectations from society
Biopsychosocial model
No single model can fully explain the presence of abnormal behaviour, examines biological, psychological, social and cultural factors
Diathesis-stress model
Diathesis indicates a predisposition to a psychological disorder. Assumes that psychological disorders may have a biological basis - presence of predisposition and a stress to set it off results in psychological disorders
Translational research
Scientific approach that focuses on communication between basic science and applied clinical research - scientific discoveries must be translated into practical applications
3 main points of ethics and responsibility
Respect for persons (subjects in study must be capable of making decisions about themselves)
Beneficence - maximizing benefits and minimize harm
Justice - fairness in distribution of what is deserved
Important points of ethnics and responsibility
Informed consent, subjects remain anonymous, research ethics boards must review studies, based on tri-council policy statement - sets standards for research ethnics
Two main parts of the nervous system
CNS (brain and spinal cord), PNS
Dendrite
Tree-like branches that receive messages from the neurons
NTM
Chemicals that transmit information to and from the neurons
Soma
Keeps the cell alive, cell body containing the nucleus
Axon
Tube-like structures that carry messages to the cells
Synapse
Space between the neurons
Neuron
Nerve cell found throughout the body (86 billion nerve cells)
Brain stem
Primital, controls fundamental biological functions - breathing
Hindbrain
Medulla, pons, cerebellum (regulations breathing, heart beat, motor control, balance)
Lesion
Area of damage or abnormality
Midbrain
Coordinates sensory information and movement, houses the reticular activating system which regulates our sleep and arousal systems
Thalamus
Relay station, directs nerve signals that carry sensory data to the cortex
Hypothalamus
Homeostasis, regulation of blood pressure, body temperature, fluid and electrolyte balance and body weight
Forebrain
Cerebral cortex, plus limbic system and basal ganglia
Limbic system
Amygdala, cingulate gyrus and hippocampus - deals primarily with emotions and impulses
Hippocampus
Memory formation (linked with memory deficits)
Basal ganglia
Controls movement (finger tapping), associated with dopamine, may inhibit movement (structures within - caudate putamen, nucleus accumbens, globus plaids, substantia nigra and subthalamic nucleus)
Alzheimer’s brain
Contains greater number of plaques and tangles
Biological scarring
Changes in the brain over time with years of living with a disorder
Cerebral cortex
Higher cognitive functioning - reasoning, abstract thought, perception of time and creativity
Left hemisphere
Language and cognitive functioning, processes information in a linear and logical manner
Right hemisphere
Processes the world in a holistic manner, spatial, creativity, imagery and intuition
Each hemisphere has ..
4 lobes - temporal, parietal, occipital and frontal
Temporal lobe
Understanding auditory / verbal information and verbal memory
Parietal lobe
Integrates sensory information from various sources, visuospatial processing
Occipital lobe
Center of visual processing
Frontal lobe
Reasoning impulse control, judgement, memory, problem solving and sexual and social behaviour
Corpus callosum
Allows communication between the two hemispheres
PNS
Sensory-somatic nervous system and autonomic NS
Sensory-somatic nervous system
Nerves which control sensation and muscle movement, consists of the cranial nerves
Autonomic NS
Sympathetic NS which controls involuntary movements, activated the body and actives in presence of stress or anxiety (bodily arousal) and parasympathetic NS which returns the body functioning to resting levels
The Endocrine system
Works together twitch the CNS, a system in the body that sends messages to the bodily via hormones, endocrine glands produce hormones - released into the bloodstream to act on target organs
Pituitary gland
Master gland
Hypothalamus
Regulates the pituitary gland
Adrenal glands
Above the kidneys, releases epinephrine (adrenaline)
Thyroid glands
Regulates metabolism, body temperature and weight
