INTEGRATIVE APPROACH TO PSYCHOPATHOLOGY Flashcards
Huntington’s disease
degenerative brain disease usuallytheearly40s. This disease has been traced to a genetic defect that causes deterioration in a specificareaofthebrain, the basal ganglia
Huntington’s disease
broad changes in personality, cognitive functioning, and, particularly, motor behavior, including involuntary shaking or jerkiness throughout the body.
can result in intellectual disability, present at birth, caused by the inability of the body to metabolize(breakdown) phenylalanine, caused by a defect in a single gene
Phenylketonuria (PKU),
i ALSO KNOWN AS METAL RETARDATION
Phenylketonuria (PKU),
study individuals who have the same disorder SUCH AS EYE COLOR there might be connection of the known gene locations and possible location of a gene contributing to the disorder
linkage studies
It may occasionally turn on certain genes
The environment
a specific method of interaction between genes and environment individuals inherit tendencies to express certain traits or behaviors, which may then be activated under conditions of stress
diathesis–stress model
Each inherited tendency is condition that makes someone susceptible to developing a disorder
diathesis (vulnerability),
diathesis–stress model the smaller the vulnerability
greater the life stress required to produce the disorder
diathesis–stress model
less life stress is required.
individuals with at least two copies of the long allele (LL)
able to cope better with stress
individuals with two copies of the short allele (SS)
have a hard time coping with stress
reciprocal gene–environment another name
Gene–environment correlation
genetic endowment may increase the probability that an individual will experience stressful life events
Gene–environment correlation model or reciprocal gene–environment
complex interaction of the two, influences the development of our behavior and personalities
Neither nature (genes) nor nurture (environmental events) alone
