Document Summary
Interactions between biology and social factors suggested. The study of genetic contributions to behavior. Estimate degree to which variation in psychological characteristics is due to genetic factors. A statistic that refers to the proportion of observed variance in a group of individuals that can be accounted for by genetic variance. Described the degree to which genetic differences among individuals cause differences in an observed property (e. g. height, rest in slides) Heritability refers to the variation in the population examined in a given study. If h^2 is less than 1. 0, there exists variance that is not accounted for by genetic factors. H^2 does not indicate the degree (rest in slides) H^2 of . 40 for inhibition does not mean that 40% of that trait is inherited. H^2 of . 40 for inhibition means that genetics accounts for 40 percent of the variability between the people in the population studied.
