Studied by 23 people
motivation
a need or desire that energizes and directs behavior
instinct
a complex behavior that is rigidly patterned throughout a species and is unlearned
physiological need
a basic bodily requirement
drive-reduction theory
the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need
homeostasis
A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level
incentive
a positive or negative environmental stimulus that motivates behavior
Yerkes-Dodson Law
the principle that performance increases with arousal only up to a point, beyond which performance decreases
hierarchy of needs
Maslow's pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level safety needs and then psychological needs become active
glucose
the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.
