Motivation
The process that initiates, guides, and maintains goal-oriented behaviors. It involves biological, emotional, social, and cognitive forces that activate behavior.
instinct
A complex behavior that is rigidly patterned throughout a species and is unlearned.
physiological need
A biological requirement for survival, such as the need for air, water, food, shelter, and sleep.
drive reduction theory
A theory that suggests 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
A simple sugar that is an important source of energy.
set point
The point at which an individual’s “weight thermostat” is supposedly set. When the body falls below this weight, an increase in hunger and a lowered metabolic rate may act to restore the lost weight.
basal metabolic rate
The body’s resting rate of energy expenditure.
asexual
Having no sexual attraction to others.
testosterone
The most important of the male sex hormones. Both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.
estrogens
Sex hormones, such as estradiol, secreted in greater amounts by females than by males and contributing to female sex characteristics. In nonhuman female mammals, estrogen levels peak during ovulation, promoting sexual receptivity.
sexual response cycle
The four stages of sexual responding described by Masters and Johnson - excitement, plateau, orgasm, and resolution.
refractory period

affiliation need
The need to build relationships and to feel part of a group.

achievement motivation
A desire for significant accomplishment; for mastery of skills or ideas; for control; and for attaining a high standard.
grit
Passion and perseverance in the pursuit of long-term goals.
emotion
A response of the whole organism, involving physiological arousal, expressive behaviors, and conscious experience.
james lange theory
The theory that our experience of emotion is our awareness of our physiological responses to an emotion-arousing stimulus.
cannon bard theory
The theory that an emotion-arousing stimulus simultaneously triggers physiological responses and the subjective experience of emotion.
