Document Summary
Comparison between theorists on second midterm and those in the first midterm. Extroverts have low arousal, which is received slowly and dies down quickly. Have higher pain threshold, since they do not respond to pain stimulation. Introverts are over aroused, so introversion is to decrease arousal. Faster pupillary contraction due to easier uptake of stimulation; slower dilation, since dilation is inhibition of contraction. Extroverts more likely to exhibit psychopathy slower to learn/fail to learn ethics, morals and so on. Introverts more likely to suffer from anxiety responses introverts learn more, including anxiety responses. Only intense trauma leads to small emotional response. Only small trauma is needed to trigger emotional response. High levels of testosterone most psychotic people are males. Low mao: enzyme that degrades monoamines such as dopamine, ne, e. Breaking down nts reduces ability to activate post-synaptic neuron. 40-50% of variance in characteristics (extrovert/introvert) are inherited (genetic)
