Document Summary
Biological paradigm- clinicians are often looking for a marker for different disorders. Behavioural genetics: study of individual differences in behavior that are attributable in part to differences in genetic makeup, in other words, our dna. And the way in which we conceptualize our genetics is by either genotype or phenotype. Interplay between development and psychosocial world a person lives in. Family method: is used to study a genetic predisposition among members of a family because the average number of genes by two blood relatives is known; great way of creating a quasi- experiment. If a predisposition for mental illness can be inherited, a study of family should reveal a relationship between the number of shared genes and the prevalence of a disorder. Example, schizophrenia- if mom and dad both have the disorder, then what is the chance for the child to have the disorder- 20%, an increase from 1% for a child with parents without the disorder (idiopathic)
