PS280 Lecture Notes - Lecture 2: Twin, Social Learning Theory, Cognitive Restructuring
Document Summary
Current paradigms: biological, psychoanalytic, humanistic, learning (behavioural, cognitive. People inherit a genetic predisposition to develop on for more. Genotype (genetic makeup- cant see it) vs. phenotype (expression of the genetic make up- phenotype and the environment, what we disorders. Biological paradigm: focusing on behaviour genetics and biochemistry, behaviour genetics** can see, behaviour genetics research methods disorder, twin method, adoption studies, family method. Identify an individual with a disorder, then look to see the number of relatives that also meet the criteria for that. Criticism that it is not just genes shared between family. Would identify if both twins have the disorder (greater in identical twins rather than fraternal twins) Families that have given their babies up for adoption and look for those adopted babies: linkage analysis the rate of the disorder within. How biochemistry is implicated in psychopathology: amount of neurotransmitter: too much or too little, receptor sites: too many, easily excited. Stimulants: electroconvulsive therapy (ect, deep brain stimulation.
