4 ) Two components of motivation drive and arousal
Hull’s drive reduction theory
-proposes that biological needs of deficiencies increase our drives or arousal level
-all of our behavior is geared towards satisfying these needs and reducing drive down to a “0” level
E=DxH probability of equals drive x habit strength
A R
-you have an arousal level once we satisfy arousal level that has reached “0”
-we are motivated to keep our drive level at 0.
INCENTIVE anticipated reward
-learned though past experience
-habit strength= how easy it is for you to perform
E=DxH (steak with for and knife)
10x10
0x10 (full stomach)
10x0 (2 year old + steak)
Drive theory how internal states push you
(push)
Incentive Theory how external stimuli “pull” you
(pull)
Hebb’s Optimal level of arousal theory
-when arousal is too high or too low, we try to attain an ideal optimal level
Low •-------------------------------|--------------------------•high
Optimal arousal
-Diurnal Variation the arousal change during the day
Eysencle ?
Extraverts have a naturally low level of arousal
Introverts quiet, cautious have naturally high level also people in the middle
performing at your peak
increasing beyond optimal=backfire
high
Low Optimal Arousal
