Q

Which classical temperament reaches transmarginal inhibition first? and why?

Q

Hebb’s motivation theory

A

non specific cortical arousal affects mood at high and low arousal. optimal in inverted U. we are motivated to find an intermediate level that is optimal for performance AND pleasant

Q

Hebbs motivation: Introverts experience Stimuls ____
