unit 7a - motivation, emotion, and stress Flashcards
motivation
a need or desire that energizes and directs behavior
evolutionary/instinct theory
a motivational theory that focuses on genetics & how genes predispose species.
criticisms: fails to focus on the role of learning in human behavior. labels behavior but doesn’t explain it
drive reduction theory
a motivational theory that states a need results in a drive which motivates the organism to act to reduce the tension & return the body to homeostasis
criticisms: it doesn’t explain why people continue to engage in a behavior after a drive is reduced
arousal theory
a motivational theory that says people are motivated to maintain their optimal level of arousal, increasing arousal, when it is too low & decreasing it when it is too high
yerkes-dodson law
the principle that performance increases with arousal only up to a point, beyond which performance decreases. moderate arousal leads to optimal performance
hierarchy of needs
abraham maslow proposed that there is a pyramid of human needs. starts with physiological needs that must be first satisfied before motivated to satisfy higher-level needs
hierarchy of needs levels (bottom to top)
physiological needs, safety needs, love and belonging, esteem, self-actualization
factors of hunger
the brain monitors blood chemistry and hormones whose presence communicates hunger
leplin
protein hormones secreted by fat cells; causes brain to increase metabolism and decrease hunger when abundant
lateral hypothalamus
tells us when we are hungry
ventramedial hypothalamus
tells us when we are full
affiliation need
a deep need to belong, working hard to build relationships, influenced by social networking
achievement motivation
a desire for significant accomplishment, mastery of skills or ideas, for control, and for attaining a high standard.
people with this achieve more and have grit
emotion
a response of the whole organism involving physiological arousal, expressive behaviors, and conscious experience
james-lange theory
a theory of emotion that claims people experience emotion based on their physiological behavior and responses
criticism: if correct, then there should be a unique physiological response for every emotion.
