Document Summary

Psychological assessment: involve examining how bodily functions (physiology) change in association with behaviors or mental states (psychology) Eeg (measures brain activity), fmri (follows o2 in brain), pet (follows glucose in brain) Epigenetics: changes in gene expression that are due to non-genetic influences. Predictor variables: type of mao-a gene (lower vs. higher = nature), maltreated during childhood or not (=nurture) Outcome variables: convicted of violent crime by age 26. Result: low mao gene + maltreated = increases probability of being a violent criminal. Heredity= genetic transmission of characteristics from parents to offspring. Heritability coefficient= estimate of genetic proportion of the variation in a specific trait. The nervous yste(cid:373): the (cid:271)ody"s ele(cid:272)tro(cid:272)he(cid:373)i(cid:272)al communication circuitry. Central nervous system = brain and spinal cord. Sympathetic nervous system = motor and sensory neurons. Peripheral nervous system = somatic and autonomic nervous system. Transmits info the cns, responds to messages from cns to perform behaviors. Autonomic nervous system = sympathetic and parasympathetic nervous system.
