Unit 8: Motivation and Emotion Flashcards
motivation
needs or desires that help us accomplish goals
goal
end result or purpose of a motivated effort
short-term goals
goals that can be accomplished in a relatively short amount of time
long-term goals
goals that are accomplished in an extended amount of time
hunger
the body’s automatic response to the need for food
What causes hunger and overeating?
Biological factors such as the hypothalamus, blood glucose level, leptin, and insulin levels, and genetic tendencies in the body to be overweight and family history
Environmental factors such as food availability, palatability, innate needs, preferences, and stress, and excessive eating and lack of exercise.
stomach-contraction theory
early theory explaining hunger stating that stomach contractions influence hunger
hypothalamus
region in brain that controls hunger
glucose
sugar that body uses as main source of energy
insulin
hormone contolling blood glucose level
ghrelin
hormone secreted by empty stomach signaling hunger to brain
orexin
hormone secreted by rain triggering hunger
leptin
hormone secreted by fat cells telling brain to not be hungry and decrease metabolism
PYY
tells brain to not be hungry, secreted by digestive tract
obesity
abnormal accumulation of body fat
BMI
measurment of weight relative to height
set-point theory
body naturally monitors weight and averages towards a determined set point
settling-point theory
weight tends to settle at a specific level unless iimpaced by outside factors
What are the two types of motivation?
intrinsic and extrinsic motivation
intrinsic motivation
enjoyment motivates behavior
extrensic motivation
rewards or avoidance of punishment motivates behavior
drive-reduction theory
physiological need creates arousal that motivates behavior to satisfy arousal
homeostasis
physiological state of internal stability
basal metabolic rate
the rate at which metabolism occurs when the body is in internal rest
arousal theory
the idea that we are motivated by optimum arousal inducing behaviors
incentive theory
states that behavior is motivated by need or avoidance of incentives
incentive
external stimuli that motivate behavior
drive
internal state of tension that motivates behavior
Instincts
innate behavior present in a species that is unlearned
Yerkes-Dodson law
a moderate level of arousal leads to optimal performance
Abraham Maslow
a humanistic psychologist that studied individuals’ potential for self-growth and freedom, described self-actualization, and developed the hierarchy of needs
self-actualization
realization of one’s full potential
Maslow’s Heirarchy of Needs
Self-actualization: live up to full potential
Esteem: independence, respect, recognition, self-esteem, achievement
Belongingness and Love: to love and to be loved, to be accepted, to avoid loneliness
Safety: to be safe and stable, to believe the world is predictable
Physiological Needs: hunger, sleep, thirst
How does arousal relate to motivation?
Arousal is a biological need that can motivate a behavior
Are some motives more basic than others
Yes, according to Maslow’s Hierarchy of Needs, needs on the bottom need to be partially met before focusing on those above, making them more basic
expectancy theory
we are motivated due to an expected outcome
emotion
subjective feeling representing one’s state of mind
What happens during emotion?
During emotion, physiological arousal is associated with an emotional response in all theories of emotion
Can lie detectors really detect lies?
No, they rather detect changes in emotion-linked behaviors such as heart rate, breathing, and pulse.
What are the three components of emotion?
Cognitive, physiological, and behavioral components
What is the cognitive component of emotion?
thinking and evaluation of events influences emotion
What is the physiological comonent of emotion?
autonomic nervous system (sympathetic and parasympathetic NS) and brain activity influences emotion
