UNIT 7 Flashcards
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 psycholgical needs become active
glucose
the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When levels are low we feel hunger
estrogens
sex hormones secreted in greater amounts by females that by males and contributing to female sex characteristics
testosterone
the most important of the male sex horomones - both males and females have it
sexual orientation
an enduring sexual attraction toward members of either one’s own sex or the other sex
motivation
a need or desire that energizes and directs behavior
instinct
a complex behavior that is rigidly patterened throughout a species and is unlearned
drive-reduction theory
the idea 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
set point
the point at which an individual’s “weight thermostat” is supposedly set
basal metabolic rate
the body’s resting rate of energy expenditure
anorexia nervosa
an eating disorder in which a person diets and becomes significantly underweight, yet, still feels fat, continues to starve - usually an adolescent female
bulimia nervosa
an eating disorder characterized by episodes of overeating followed by vomiting, laxative use, fasting, or excessive exercise
binge-eating disorder
significant binge-eating episodes, followed by distress, disgust, or guilt, but without the compnesatory puring, fasting, or excessive exercise that marks bulimia nervosa
sexual response cycle
the four stages of sexual responding described by Masters and Johnson - excitement, plateau, orgasm, and resolution
refractory period
a resting period after orgasm, during which a man cannot achieve another orgasm
emotion
a response of the whole organism involving (1) physiological arousal, (2) expressive behaviors, and (3) conscious experience
James-Lange theory
our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli
Cannon-Bard theory
emotion-arousing stimulus simultaneously triggers (1) physiological responses and (2) the subjective experience of emotion
Schachter-Singer two-factor theory
to experience emotion on must (1) be physically aroused and (2) cognitively label the arsousal
facial feedback
the effect of facial expressions on experienced emotions, as when a facial expression of anger or happiness intensifies feelings of anger or happiness
catharsis
emotional release - “releasing” aggressive energy (through action or fantasy) relieves aggressive urges
behavioral medicine
an interdisciplinary field that integrates behavioral and medical knowledge and applies that knowledge to health and disease
health psychology
a subfield that provides psychology’s contribution to behavioral medicine
stress
the process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging
general adaptation syndrome (GAS)
Selye’s concept of the body’s adaptive responses to stress in 3 phases - alarm, resistance, exhaustion
coronary heart disease
the clogging of the vessels that nourish the heart muscle; leading cause of death in North America
polygraph
a machine, commonly used in attempts to detect lies, that measure several of the physiological responses accompanying emotion
feel-good, do-good phenomenon
people’s tendency to be helpful when already in a good mood
well-being
self-perceived happiness or satisfaction with life. Used along with measures of objective well-being to evaluate people’s quality of life
adaptation-level phenomenon
our tendency to form judgments (of sounds, of lights, of income) relative to a neural level defined by our prior experience
relative deprivation
the perception that we are worse off relative to those with whom we compare ourselves
Type A
Friedman and Rosenman - competitive, hard-driving, impatient, verbally aggressive, and anger-prone people
Type B
Friedman and Rosenman - easygoing, relaxed people
psychophysiological illness
mind-body illness - any stress related physical illness
psychoneuroimmunology (PNI)
the study of how psychological, neural, and endocrine processes together affect the immune system and resulting health
lymphocytes
the two types of white blood cells that are part of the body’s immune system
B lymphocytes
form in bone marrow and release antibodies that fight bacterial infections
T lymphocytes
form in the thymus and other lymphatic tissue and attack cancer cells, viruses, and foreign substances
projection
psycholoanalytic defense mechanism by which people disguise their own threatening impulses by attributing them to others
rationalization
psychoanalytic defense mechanism that offers self-justifying explanations in place of the real, more threatening, unconscious reasons for one’s actions
