Unit 7 Pt 1: Motivation Flashcards
Motivation
Need or desire that serves to energize behavior
Behavior is guided by
Both physiological and psychological needs/desires
Instinct
Fixed action patterns
Instinct refers to
Inherited pattern of behavior that is unlearned
Instinct is most common in
Species other than humans
Instinct example
Imprinting (duckies)
Drive
Experienced as an aroused state of psychological/physiological tension caused by some need
Drive example
Sex drive
Drive motivates us to
Do something
Some psychologists say the goal of our body is to eliminate all drives so that we can experience
Homeostasis
Homeostasis
A balanced or constant internal state that the body regulates
Drive is psychological or physical?
Psychological
It is stress
Optimal arousal preference
Change depending on the individual
Optimal arousal performance
Similar for most people
Drive Reduction theory by
Clark Hull
Drive reduction theory
Physiological needs create tension states (drives) which motivates organism to satisfy the need
Drive reduction theory example
Thirstiness (physiological need) creates tension state (drive) which motivates you to drink water
After you drink the water
The drive is reduced and you are closer to homeostasis
Incentives theory
A positive or negative ENVIRONMENTAL (has to be external) stimulus that motivates behavior apart from “need” to reduce drives
Incentives theory example
Money, fame, etc.
Arousal theory 1
Individuals perform tasks at different levels of arousal (wakefulness/sleep)
Arousal theory 2
Each individual seeks to find its optimal level of arousal to perform tasks and avoid boredom
People with high levels of optimal arousal vs low
High: like thrilling things
Low: relaxing quiet activities
We are _______ to do some things to maintain our arousal
Motivated
Yerkes-Dodson Principle of arousal graph
Graph forms an inverted U
Yerkes-Dodson Principle
Basic general tasks are completed best with a moderate level of arousal
Yerkes-Dodson expanded arousal theory: difficult and skill based tasks
Moderate low arousal
Yerkes-Dodson expanded arousal theory: easy/effort based tasks
Moderate high arousal
A biological theory of hunger
Stomach contractions (hunger pangs) accompany our feelings of hunger. Balloon in stomach boy experiment
Glucose
Blood sugar that provides energy to the body’s tissues
When your glucose levels are LOW
You will feel hungry
When glucose levels are HIGH
You will feel full
Feeling of being full (food wise)
Satiety
Primary regulator of glucose levels (hormone)
Insulin
Without insulin and cause
Body doesn’t efficiently dispose of glucose and provide it as energy
Diabetes
When neurotransmitters are at low levels
You will feel hungry
When neurotransmitters are at high levels, you will feel
Full
Hunger related neurotransmitters
Norepinephrine
Dopamine
Serotonin
Hypothalamus
The main brain structure which monitors hunger along with other maintenance activities
Lateral hypothalamus
Brings on hunger
If lateral hypothalamus is destroyed
No interest in food/stimulation will do opposite
Way to remember lateral hypothalamus
LAT makes you FAT (When stimulated)
Ventromedial hypothalamus
Depresses hunger
If ventromedial hypothalamus is destroyed
Animal will overeat/stimulation will do opposite
Way to remember ventromedial hypothalamus
VEN makes you THIN (when stimulated)
Leptin
Protein produced by bloated fat cells
