Chapter 11- Motivation Flashcards
Motivation
-the moving towards one’s goal
accomplishing a task
Needs
- biological states of deficiency (cellular or bodily) that compels drives
- ex: food, water, oxygen
Drives
-tension caused by deficiency in needs
come from the body
-push us into action
-ex: hunger, thirst
Motivated behaviours
needs and drives
Incentive
- anything from the environment that motivates behaviour
- pull us into action
ex: money is the incentive to get a job, getting a uni degree is the incentive behind studying
Evolutionary theory of motivation
Major motives all involve basic survival and reproduction needs and drives: hunger, thirst, body-temperature regulation, oxygen, and sex
Desires, wants, and needs have been shaped over the course of evolution to guide behaviour either toward adaptive or away from maladaptive actions
Study of Sexual Motivation
Women kept a diary of their clothing style across their menstrual cycle
Women took picture every day, men rated clothing as sexier and the women more attractive during the fertile phase
Sexual behaviour in humans is enhanced at times when the chance of conception is most likely
Instinct
an inherited behavioural tendency
helps ensure survival
do something because it feels good, stop because it feels bad
Drive reduction model
maintaining homeostasis
Homeostasis
- physiological balance
- maintaining equilibrium around a set point
- feedback loop
Yerkes- Dodson Law
moderate levels of arousal lead to optimal performance
-low and high arousal leads to bad performance
Optimal Arousal Model of Motivation
Humans motivated to be optimally aroused (not too much and not too little)
Needs like: curiosity, learning, interest, beauty-aesthetics, competence, challenge, flow states and optimal experiences
Having a person lie down on a bed or in a sensory deprivation/salt water tank
People can’t remain in sensory deprivation for more than
People can’t remain in sensory deprivation for more than 2-3 days even if paid double their daily wage for staying
When stayed for only a few days, “pathology of boredom” developed
Long periods of sensory deprivation people begin to:
Hallucinate
Depleted cognitive and concentration
Develop childish emotional responses
long term sensory deprivation in rats
Shrinks brain regions that are involved in the deprived senses
Another example of plasticity in the brain
“Flow”
people perform best and are most creative when they are optimally/moderately challenged
Maslows hierarchy of needs
1) Physiological needs
2) Safety and security needs
3) Love and belonging needs
4) Esteem needs
5) Self actualization
only once lower levels have been satisfied, can you reach the highest levels
physiological needs
-lowest level
food, water, oxygen body temp
safety and security needs
-safety and protection from danger
love and belonging needs
need to have friends, family, a mate, sex, children
esteem needs
need to be appreciated and respected
self actualization
full realization of your potential and abilities
Kenrick’s Evolutionary Model of Motivation
replaces self actualization with 3 reproductive goal
1) acquiring a mate
2) retaining a mate
3) parenting
Two basic drive states
hunger and sex
metabolism
rate at which we consume energy
-When our energy has been depleted, hunger drives us to replenish it by eating
Drive-reduction perspective of hunger
being hungry depends not only on how much food we have consumed recently, but also on how much energy is available for organ function
4 biological components of hunger
Stomach
Blood
Brain
Hormones and neurochemicals
The Stomach
-Growling results from gastric secretions hat are activated by the brain when we think of, see, or smell food
Hunger can also cause the stomach to contract
