Document Summary
Up: in adolescence (young ppl are open to new things) Down: in old age (old peeps are lame) Up: in old age - in general more accomodating: more rigid in beliefs but more easy-going. Perhaps bc the people who settles north america were more adventurous: we are biased toward seeing extraversion as the positive end. But in eastern cultures, very often they are biased towards the introversion. Like eysenck, he is trying to tie in and relate these high level constructs to low level constructs. Mao is an enzyme found around the synapse, breaks down molecules of nt limiting the amount of excitation that they can cause. Low mao means high levels of dopamine (less breakdown) Just like eysenck argued extroverts have low level of brain activity relative to optimal level, zuckerman says hish sensation seekers have low dopamine activity compared to the optimal level. Everyone has the same optimal level of brain activity.
