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
Zuckerman Sensation Seeking Theory
-There is a strong biological predisposition to high or low sensation seeking
-people have a naturally low arousal, they will tend to be high sensation seekers
1) B, A, B, A, B, B, A, B, A , B, B, A, B

Characteristics of high S.S
1) Thrill of adventure seeking
2) Experience seeking
3) Disinhibition

Solomon’s Opponent Process Theory
-The nervous system has a tendency to counteract only deviation from normalcy
-if there is too much of a swing to one pole of emotions the opponent process kicks in an emotion will
trigger a + emotional. Vice versa
Homeostasis
-emotions too high (strong) nervous system tries to counteract it to put back in steady state
Conflict Motivation
-conflict-exists where there are 2 or more competing motives
a) approach motive
b) avoidance motive
Types of conflicts
1) Approach- approach conflict
(+)(+)
2) Avoidance-avoidance-conflict
(-)(-)
3) Approach- avoidance
(+-)
As you reach the end goal the avoidance tendency decreases approach tendency.

-first words are base on behaviour
