Theories of motivation: freud"s theory life and death instincts, sociobiological theory. Everything we do is done with the intention of passing our genes on to future generations: instincts. Fixed action patterns: hull"s drive reduction theory. Biological needs/deficiencies increase our level of drive/ arousal (hull is credited with coming up with the use of the word drive in this context. All behaviour is geared toward satisfying these needs and thus reducing our drive/arousal to a lever of 0 . Neglected to take into account incentives (which are learned) Hull came up with the equation e = d*h where e is the probability of a reaction, d is drive and h means habit strength. Drive theories: how internal states push us. Incentive theories: how external states pull us: hebb"s optimal level of arousal theory. When arousal is too high/too low, we"re motivated to attain an optimal level. High e c n a m r o f r e.
