Document Summary
Sociability (how responsive a person is to other people) Used direct and observable measures (lab setting) Inhibited (avoid people that are unfamiliar, distressed by unfamiliarity, restrained: take a longer time to relax in a new situation, timid and cautious, seek parental comfort.

Amygdala (fear and anger: uninhibited have same amygdala activity when presented with novel and familiar stimuli. Stathmin (protein) influence of gene: mice with and without the stathmin gene, changed reactivity in mice when in fear.
