Chapter 2 Summary
Models of Abnormal Behavior
➢ see this slide
Dimensions of Integrative Model
➢ biological factors
o genetics, physiology, neurobiology
➢ learning factors
o classical and operant conditioning, modeling
➢ emotional factors
o affect, action tendencies
➢ cognitive factors
o implicit thoughts, schemata
➢ social factors
o networks, gender, SES
➢ cultural factors
o cultural teachings about emotional expression, relationships
Biology – Genetic Contributions
➢ genetic contribution to psychopathology less than 50%
➢ psychological disorders tend to by polygenic, meaning that more than one gene contributes to their
development
Gene-Environment Interactions
➢ Eric Kandel (1983) suggested learning can affect genes
➢ Diathesis-stress model
o Diathesis = inherited genetic vulnerability
o Stress + genetic vulnerability = disorder
➢ Reciprocal gene-environment model (people with certain genetic configurations might seek
out environments that lead them vulnerable. People vulnerable to depression might seek
out environments that lead them vulnerable)
o Environment affects genes and genes affect environment
o E.g., genes may influence the environments that people seek out, which, in turn, contribute to
psychopathology
➢ Non-genomic inheritance of behaviour (there’s a way to inherit behaviour that is not
necessarily genes. Certain behaviours can be passed on to young, who don’t share the same
genetic material)
o Behaviours are passed on to juveniles who do not share genes
o Thus, GENES ARE NOT THE WHOLE STORY
Biology – Neuroscience
➢ Neuroscience studies the role of the nervous system in disease and behaviour
The Nervous System:
➢ central nervous system (CNS)
o brain and spinal cord
➢ peripheral nervous system (PNS)
o somatic and autonomic branches
