unit 7 motivation, emotion, and personality Flashcards
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’s pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level safety needs and ten 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
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; overweight individuals have a BMI of 25 or higher
asexual
having no sexual attraction to others
sexual response cycle
the four stages of sexual responding described by Masters and Johnson - excitement, plateau, orgasm, and resolution
refractory period
a human sexuality, a resting period that occurs after orgasm, during which a person cannot achieve another orgasm
affiliation need
the need to build relationships and to feel part of a group
ostracism
deliberate social exclusion of individuals or groups
narcissism
excessive self-love and self-absorption
achievement motivation
a desire for significant accomplishment, for mastery of skills or ideas, for control, and for attaining a high standard
grit
in psychology, passion and perseverance in the pursuit of long-term goals
emotion
a responses of the whole organism, involving 1) physiological arousal, 2) expressive behaviors, and 3) conscious experience
James-Lange Theory
the theory that our experience of emotion is our awareness of our physiological responses to an emotion-arousing stimulus: stimulus S arousal S emotion
Cannon-Bard Theory
the theory that an emotion-arousing stimulus simultaneously triggers 1) physiological responses and 2) the subjective experience of emotion
two-factor theory
beginning about age 2, the stage in speech development during which a child speaks mostly in two-word statements
