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

incentive

a positive or negative environmental stimulus that motivates behavior

Yerkes-Dodson Law

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.

intelligence quotient (IQ)

defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 [thus, IQ = (ma/ca) x 100]. On contemporary intelligence tests, the average performance for a given age is assigned a score of 100.
