Document Summary

Outline: overview of evidence in different research domains, implications of meta-analytic findings, multiple disease states, gene environment interaction, pathway theory, current trends. What is the psychological consequence of hypokrisia: hypochondria, hyperactivity, cognitive slippage--a, aversive drift. How does meehl"s theory account for the etiology of schizophrenia: multiple genes ,each with a small effect, one schizogene, but multiple potentiating genes--a, no genes, but faulty parenting, one main gene, plus an aversive environment. Which of the following represents the neurogenesis of schizophrenia in meehl"s theory: cognitive slippage caused by genes, nigrostriatal dopamine hyperactivity, hypokrisia caused by neuronal firing--a, cell migration failures. Why do some people with the schizogene never develop schizophrenia: because they took section f of psyc4080, because they are compensated schizotypes--a, because they have phenocopies, because they do not have hypokrisia. What is an important weakness of meehl"s theory: key aspects are hard to measure and evaluate precisely--a, single genes cannot cause disease, positive symptoms are neglected, hypokrisia does not exist.
