Motivation (Modules 36-39) Flashcards
Motivation
An internal state that energizes and directs behavior
Instinct
A complex behavior that is rigidly patterned throughout a species and is unlearned
What is the underlying assumption of evolutionary psychology’s motivation theory?
Genes predispose species’ typical behavior
Drive-Reduction Theory
The idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy that need
Homeostasis
Tendency to maintain a balanced or constant internal state; the regulation of any aspect of body around a particular level
Incentives
A positive or negative environmental stimulus that motivates behavior
Optimum arousal theory
Human motivation aims not to eliminate arousal but to seek optimum levels of arousal (Ex. When you are at an optimum level of stress, you are at peak performance and efficiency.)
Hierarchy of Needs
Maslow’s pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level needs can be fulfilled
Order of Maslow’s Hierarchy of Needs (from bottom to top)
Physiological, Safety, Belonging and Love, Esteem, Self-actualization, Self-transcendence
Is your stomach the only place where the feelings of hunger come from?
No, they also come from the brain.
Glucose
The form of sugar that circulates in the blood and provides the major source of energy for body tissues
What part of the brain integrates glucose messages and hunger pains?
Hypothalamus – the lateral hypothalamus induces hunger while the ventromedial hypothalamus depresses hunger
Insulin
Secreted by the pancreas; controls blood glucose
Leptin
Secreted by fat cells; increases metabolism and decreases hunger
Orexin
Secreted by the hypothalamus; triggers feelings of hunger
