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
polygraph
a machine used in attempts to detect lies that measures several of the physiological responses (such as perspiration, heart rate, and breathing changes) accompanying emotion
facial-feedback effect
the tendency of facial muscle states to trigger corresponding feelings such as fear, anger, or happiness
behavior feedback effect
the tendency of behavior to influence our own and others’ thoughts, feelings, and actions
stress
the process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging
