Document Summary
View abnormal behaviour as multiply determined by emphasizing an integrative system of influences implies that any particular influence contributing to psychopathology cannot be considered out of context. Better represent the data e. g. judy"s blood injury injection phobia. Stress - quality, quantity and timing: b, 2)a or c, 3)e, 4)a (initial) or c(maintenance) Nature vs. nurture environmental factors, in the form of social and cultural in uences, can determine whether genes are turned on. 1,200 twins spanning 35 years confirmed that during adulthood genetic factors determined stability in cognitive abilities, whereas environmental factors were responsible for any changes. For psychological disorders, the evidence indicates that genetic factors make some contribution to all disorders but account for less than half of the explanation. Eric kendel: the environment may occasionally turn on certain genes. Biologically inherited tendencies or diathesis/vulnerability expressed only under certain conditions or stressors. Genes may increase the probability that an individual will experience stressful/traumatic life events.
