Motivation, Stress, Emotion Flashcards
What is motivation?
A need or desire that energizes behavior
What is instinct theory?
A theory that focuses on genetically predisposed behavior
What is the arousal theory?
The theory that you perform activities to upkeep or maintain moderate arousal
What theory was simply naming behaviors but not explaining them?
The instinct theory, or Darwin’s evolutionary theory
What is an instinct?
It is an unlearned behavior patterned throughout a species
Ex.: a baby’s innate reflexes for rooting and sucking
What does evolutionary psychology state about genes and its relation to behavior?
Genes predispose species-typical behavior
What is the drive reduction theory?
A physiological need creates a state of arousal that drives the organism to satisfy the need
Ex.: if you need food (biological need), it causes a drive (hunger), and you eventually satisfy the need (eating), to achieve a state of homeostasis
What are incentives?
It is a positive or negative stimuli that lures/compels or repels us
When we experience both of these things, we are strongly driven. What are they?
A need and an incentive
Ex.: a food deprived person who smells baking bread feels a strong hunger drive. In the presence of that drive, the baking bread becomes a compelling incentive
What is the optimal arousal theory?
The theory that some motivated behaviors actually increase arousal
Ex.: it drives adventurers to explore, even do something crazy like climb Mount Everest
What is Yerkes-Dodson law?
The principle that optimal performance can be achieved with a certain level of arousal, but beyond a certain point performance will decrease
Ex.: when taking an exam, it’s good to be moderately aroused (nervous or anxious), but if you are trembling and are too anxious, it can impair your performance
What is Maslow’s hierarchy of needs?
Physiological needs, safety needs, belongingness and love, self esteem, self actualization
To assess to a higher level, you must have previously achieved the levels below it
The self transcendence level is located above the self actualization level in Maslow’s pyramid. What is it?
It is the level where people strive for meaning, purpose, and communion that is beyond the self, that is transpersonal (dealing with areas of consciousness beyond the limits of personal identity)
What happens when glucose is low?
We feel hungry
It is major source of energy for body tissue
Where is the hormone insulin secreted? What does it control?
Secreted by pancreas
Control blood glucose
Where is the hormone ghrelin secreted? What does it do?
Secreted by the empty stomach
Sends “I’m hungry” signal to the brain
What does the hormone orexin do? Where is it secreted?
It is a hunger triggering hormone
Secreted by the hypothalamus
What is the hormone leptin? Where is it secreted? What happens when it is abundant?
It is a protein hormone
It is secreted by fat cells
When abundant, causes brain to increase metabolism and decrease hunger
What is the hormone PYY? What signal does it send to the brain?
It is a digestive tract hormone
Sends “I’m not hungry” signals to the brain
What is a set point?
The point where an individual’s weight thermostat is supposedly set.
When the body falls below this weight, an increase in hunger and lower metabolic rate may act to restore the lost weight.
What is neophobia?
When you dislike things that are unfamiliar to you
