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 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 pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before high-level safety needs become active
maslows hierarchy 1
physiological needs
maslows hierarchy 2
safety needs
maslows hierarchy 3
belongingness and love needs
maslows hierarchy 4
esteem needs
maslows hierarchy 5
self-actualization
maslows heirarchy 6
self transcendence needs
instinct motivation
a genetic basis for unlearned, species-typical behavior(birds building nests)
drive- reduction motivation
a physiological need creates an aroused psychological drive that motivates a drive-reducing behavior
arousal motivation
our need to maintain an optimal level of arousal motivates behaviors that meet no physiological need
maslows hierarchy of needs motivation
we prioritize survival-based needs and then social needs more than the needs for esteem and meaning
glucose
the form of sugar that circulates in the blood and provides the major source of energy for body tissue; when the level is low, we feel hunger
set point
the point. at which your “weight thermostat” may be set. when your body falls below this weight, increased hunger and a lowered metabolic rate may combine to restore lost weight
basal metabolic rate
the body’s resting rate of energy output
obesity
defined as a body mass index(BMI) measurement of 30 or higher
asexual
having no sexual attraction to the other
testosterone
the most important male sex hormone
