Motivation, Emotion, and Stress Flashcards
A need or desire that energizes and directs behavior.
Motivation
A complex, unlearned behavior that is rigidly patterned throughout a species.
Instinct
The idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need.
Drive-Reduction Theory
A tendency to maintain a balanced or constantly internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level.
Homeostasis
A positive or negative environmental stimulus that motivates behavior.
Incentive
The principle that performance increases with arousal only up to a point, beyond which performance decreases.
Optimal Arousal Theory Or Yerkes Dodson Law
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.
Hierarchy of needs
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.
Glucose
The point at which and 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.
Set Point
The body’s resting rate of energy expenditure.
Basal Metabolic Rate
Hormone secreted by pancreas; controls blood glucose.
Insulin
Hormone secreted by empty stomach; send “I’m hungry” signals to the brain.
Gherlin
Hunger-triggering hormone secreted by hypothalamus.
Orexin
Protein hormone secreted by fat cells; when abundant, causes brain to increased metabolism and decrease hunger.
Leptin
Digestive tract hormone; sends “I’m not hungry” signals to the brain.
PYY
The four stages of sexual responding described by masters and Johnson are?
Excitement, plateau, orgasm, and resolution.
A resting period after orgasm, during which a man cannot achieve another orgasm.
Refractory Period
A problem that consistently impairs sexual arousal or functioning.
Sexual dysfunction
Sex hormones, such as estradiol, in greater amounts by females than by males contributing to female sex characteristics. In nonhuman mammals, estrogen levels peak during ovulation, promoting sexual receptivity.
Estrogens
The most important of the male sex hormones. Both males and females have it, but the additional ______ in males stimulates growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.
Testosterone
A response of the whole organism, involving (1) physiological arousal, (2) expressive behaviors, and (3) conscious experience.
Emotion
The theory that our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli.
James-Lange Theory
The theory that an emotion-arousing stimulus simultaneously triggers (1) physiological responses and (2) the subjective experience of emotion.
Canon-Bard Theory
The Schacter-Singer theory that to experience emotion one must (1) be physically aroused and (2) cognitively label the arousal.
Two-Factor Theory
A machine, commonly used in attempts to detect lies, that measures several of the physiological responses (such as perspiration and cardiovascular breathing changes) accompanying emotion.
Polygraph
The tendency of facial muscle states to trigger corresponding feelings such as fear, anger, or happiness.
Facial Feedback Effect
A subfield of psychology that provides psychology’s contribution to behavioral medicine.
Health Psychology
The process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging.
Stress
Selye’s concept of the body’s adaptive response to stress in three phases-alarm, resistance, and exhaustion.
General Adaptation Syndrome
Under stress, people (especially women) often provide support to others and bond with and seek support from others.
Tend-and-befriend response
Literally, “mind-body” illness; any stress-related physical illness, such as hypertension and some headaches.
Psychophysiological Illness
The study of how psychological, neural, and endocrine processes together affect the immune system and resulting health.
Psychoneuralimmunology
The two types of white blood cells that are part of the body’s immune system: B ______ form in the bone marrow and release antibodies that fight bacterial infections; T _______ form in the thymus and other lymphatic tissue and attack cancer cells, viruses, and foreign substances.
Lymphocytes
The clogging of the vessels that nourish the heart muscle; the leading cause of death in many developed countries.
Coronary Heart Disease
Friedman Rosenman’s term for competitive, hard-driving, impatient, verbally aggressive, and anger-prone people.
*Type A
Friedman and Rosenman’s term for easygoing, relaxed people.
*Type B
