Chapter 3 Flashcards
A factor that co-varies with, or is associated with, some outcome of interest (eg. height and weight)
Correlate
A correlate that occurs before some outcome of interest (eg. depression is a risk factor for suicide)
Risk factor
A risk factor that can change within a person (eg. level of depression can vary within a person.)
Factor
A risk factor that cannot change within a person (eg. race cannot vary within a person, and white race is a market of increased risk of suicide death).
Fixed marker
A variable risk factor that, when changed, doesn’t influence the outcome of interest (ie. it can vary, but it is still a marker of increased risk for the outcome of interest.)
Variable marker
A variable risk factor that, when changed, changes the likelihood of the outcome of interest (eg. if effectively treating depression decreased the risk of suicide, we would call it a causal risk factor.)
Causal risk factor.
A condition that must exist for a disorder to occur. (Eg. General paresis - cannot develop unless a person has previously contracted syphilis.)
Necesssary cause.
A condition that guarantees the occurrence of a disorder. (If X occurs, then Y will also occur.)
Sufficient cause.
A condition that increases the probability of developing a disorder but that is neither necessary nor sufficient for it to occur. (If X occurs, then the probability of Y occurring increases.)
Contributory cause.
Factors occuring relatively early in life that may not show their effects for many years.
Distal risk factors.
Risk factors that operate shortly before the occurrence of the symptoms of a disorder.
Proximal risk factors.
A condition that tends to maintain maladaptive behavior that is already occurring. (Eg. Extra attention, sympathy, and relief from unwanted responsibility that may come when a person is ill, these pleasant experiences may unintentionally discourage recovery.)
Reinforcing contributory cause.
When more than one causal factor is involved that lead to a condition. (Eg. Conditions A,B,C lead to condition Y.)
Causal pattern
View of abnormal behavior as the result of stress operating on an individual who has a biological, psychosocial, or socicultural predisposition to developing a specific disorder.
Diathesis-Stress model.
Predisposition or vulnerability to developing a given disorder.
Diathesis.
Effects created within on organism by the application of a stressor.
Stress.
When the diathesis and stress simply add up, or sum together.
Additive model.
Model of when some amount of diathesis must be present before stress will have any effect.
Interactive model.
Influences that modify a person’s response to an environmental stressor, making it less likelt that the person will experience the adverse effects of the stressor.
Protective factors.
Effect of when some stressors paradoxically promote coping.
“steeling” or “inoculation”
The ability to adapt successfully to even very difficult circumstances.
Resilience.
Field of psychology that focuses on determining what is abnormal at any point in the developmental process by comparing and contrasting it with normal and expected changes that occur.
Developmental psychopathology.
A _____________ cause is one that must exist in order for a disorder to occur.
Ncessary.
The ability to adapt successfully to even very difficult circumstances is called _______________.
Resilience.
Research suggests that childhood abuse is associated with the risk of developing depression later in life. However, not everyone who experiences childhood abuse develops depression, and many people who develop depression did not experience childhood abuse. Childhood abuse is thus which of the following?
A contributory cause of depression.
A viewpoint that acknowledges the interacting roles of biological, psychosocial, and sociocultural factors in the origins of psychopathology.
Biopsychosocial viewpoint.
The ____________ perspective focuses on how genetics, neurobiology, and hormonal responses influence psychopathology.
Biological.
The _____________ perspective is concerned with thoughts, feelings, and behaviours.
Psychological.
The ________________ perspective focuses on social and cultural factors.
Sociocultural.
The ________________ viewpoint is an integrated approach.
Biopsychsocial.
Julia’s friend explains that she struggles with alcoholism because of “bad genes.” This explanation represents the __________ perspective of abnormal behavior.
Biological
Dr. Austin takes an approach to understanding psychopathology that considers the way in which multiple types of influences affect one’s mental functioning. He also pays attention to the cultural context in which behaviors occur to determine what is and is not considered to be abnormal. Dr. Austin adheres to the __________ model.
Biopsychosocial
Dr. Yang studies psychopathology by investigating how dysfunctional thoughts, feelings, and behaviors can contribute to abnormal behavior. Dr. Yang is looking at behavior from a __________ perspective.
Psychological.
There are four categories of biological factors relevant to the development of maladaptive behavior… what are they?
- Genetic vulnerabilities.
- Brain dysfunction and neural plasticity.
- Neurotransmitter and hormonal abnormalities in the brain and other parts of the nervous system.
- Temperament.
Long molecules of DNA that are present at various locations on chromosomes and that are responsible for the transmission of hereditary traits.
Genes.
Chain like sstructures wihtin cell nucleus that contain genes.
Chromosomes.
Genes are the carriers of the information that we inherit from our parents, and each gene exists in two or more alternate forms called ____________.
Alleles.
Personality traits and mental disorders are not affected by chromosomal abnormalities. Instead they are more often influenced either by abnormalities in some of the genes on the chromosomes or by naturally occurring variations of genes known as _______________.
Polymorphisms.
Caused by the action of many genes together in an additive or interactive fashion.
Polygenic.
A persons total genetic endowment.
Genotype.
The observed structural and functiontion characteristics of a person that result from interaction between the genotype and the environment.
Phenotype.
Differential sensistivity or susceptibility to their environments by people who have different genotypes.
Genotype-environment interaction.
Genotypic vulnerability that can shape a childs environmental experiences. (Eg. A child who is genetically predisposed to aggressive behaviour may be rejected by his or her peers in early grades because of aggressive behaviour. Such rejection leads the child to go on to form friendships with other deliquent peers.)
Genotype-environment correlation.
The childs genotype may have what has been termed a _____________ on the environment, resulting from the genetic similarity of parents and children. (Eg. Highly intelligent parents may provide a highly stimulating environment for their child, thus creating an environment that will interact in a a positive way with the child’s genetic endowment for high intelligence.)
Passive effect.
The childs genotype may evoke particular kinds of reactions from the social and physical environment. (Eg. Happy babies draw out more positive responses from others than do passive, unresponsive infants.)
Evocative effect.
The childs genotype may play a more active role in shaping the environment. (Eg. Extraverted children may seek the company of others, thereby enhancing their own tendeencies to be sociable.)
Active effect.
Field that studies the heritability of mental disorders and other aspects of psychological functioning such as personality and intelligence.
Behavior genetics.
The three primary methods that have traditionally been used in behavior genetics are?
- The family history method.
- The twin method.
- The adoption method.
Behaviour genetic research strategy that examines the incidence of disorder in relatives of an index case to determine whether incidence increases in proportion to the degree of hereditary relationship.
Family history method.
The use of identical and nonidentical twins to study genetic influences on abnormal behavior.
Twin method.
Twins that share the same genetic endowment because they develop from a single zygote.
Identical.
The percentage of twins sharing a disorder or trait.
Concordance rate.
These twins develop from two different fertilized eggs and do not share any more genes than do siblings from the same parent.s
Dizygotic twins.
Comparison of biological and adoptive relatives with and without a given disorder to assess genetic versus environmental influences.
Adoption method.
True/ False: Strong genetic effects mean that environmental influences must be unimportant.
False; Environmental factors can have a major inpact on the level of that trait.
True/ False: Genes impose a limit on potential.
False, one’s potential can change if one’s environment changes.
True/ False: Genetic strategies are of no value for studying environmental influences.
False; Genetic research strategies provide critical tests of environmental influences on personality and psychopathology.
True/ False: Genetic effects diminish with age.
False: Although many people assume that genetic effects should be maximal at birth, with environmental influences getting stronger with increasing age, it is now evident that this is not always true.
True/ False: Disorders that run in families must be genetic, and those that do not run in families must not be genetic.
False: Many examples contradict these misconceptions. Teenage onset juvenile delinquency for example, tends to run in families, and yet this seems to be due primarilly to environmental rather than genetic influences.
______________________ are those that would make children in a family more similar, whether the influence occurs within the family or in the environment.
Shared environmental influences.
______________________ are those in which the children in a family differ. These would include unique experiences at school and also some unique features of upbringing in the home, such as a parent treating one child in a qualitatively different way from another.
Nonshared environmental influences.
These types of studies attempt to deetermine the actual location of genes responsible for mental disorders.
Linkage analysis and association studies.
Genetic research strategy in which occurrence of a disorder in an extended family is compared with that of a genetic marker for a physical characteristic or biological processes that is known to be located on a particular chromosome.
Linkage analysis.
Genetic research strategy comparing frequenct of certain genetic markers known to be located on particular chromosomes in people with and without a particular disorder.
Association studies.
_____________________ is the felxibility of the brain in making changes in organization and function in response to pre-and postnatal experiences, stress, diet, disease, drugs, maturation, and so forth.
Neural plasticity.
Achknowledgement that genetic activity infleunces neural activity, which in turn infleunces behavior, which in turn influences the environment, and that these influences are bidirectional.
Developmental systems approach.
Site of communication from the axon of one neuron to the dendrites or cell body of another neuron - a tiny filled space between neurons.
Synapse.
Chemical substances that are released into a synapse by a presynaptic neuron and that transmit nerve impulses from one neuron to another.
Neurotransmitters.
One of the basic tenants of the biological perspective today?
The belief that imbalances in neurotransmitters in the brain can result in abnormal behaviour.
Neurons that are sensitive to a particular neurotrasnmitter tend to cluster together, forming neural paths between different parts of the brain known as _________________.
Chamical circuits.
Five different kinds of neurotrasmitters have been most extensively studies in relationship to psychopathology. What are they?
- Norepinephrine.
- Dopamine
- Serotonin
- Glutamate
- Gamma aminobutyric acid. (GABA)
Norepinephrine, dopamine, and serotonin belong to a class of neurotransmitters called? Why?
Monoamines. Because each is synthesized from a single amino acid.
Medication that facilitate the effects of a neurontransmitter on the postsynaptic neuron are called _____________.
Agonists.
Medications that oppose or inhibit the effects of a neurotransmitter on a postsynpatic neuron are called _________________.
Antagonists.
