Introduction Motivation
Motivation = a need or desire that energizes and directs behavior.
Instincts and Evolutionary Psychology Instinct (fixed pattern) Instincts in animals Instincts in humans
Instinct = a complex, unlearned behavior that is rigidly patterned throughout a species.
Drives and Motivations Drive-reduction theory Homeostasis Need Drive Drive reduction
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.
Drives and Motivations Incentive Positive and negative
Incentive = a positive or negative environment stimulus that motivates behavior.
Optimum Arousal Arousal Optimum level of arousal Yerkes-Dodson Law
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.
A Hierarchy of Motives
Motivational Theories Strengths and Weaknesses
The Physiology of Hunger Contractions of the stomach Washburn study
The Physiology of Hunger Body Chemistry and the Brain Glucose Insulin Hypothalamus Lateral hypothalamus orexin Vetromedial hypothalamus
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.
The Physiology of Hunger Body Chemistry and the Brain Appetite hormones Ghrelin Obestatin PYY Leptin Set point Basal metabolic rate
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.
The Physiology of Hunger Body Chemistry and the Brain
The Psychology of Hunger Taste Preferences: Biology and Culture Taste preferences Genetic: sweet and salty Neophobia Adaptive taste preferences
The Psychology of Hunger Taste Preferences: Biology and Culture
The Psychology of Hunger Situational Influences on Eating Do you eat more when eating with others? Unit bias Food variety
Obesity and Weight Control The Physiology of Obesity Set point and metabolism The genetic factor The food and activity factors Social influence

The Physiology of Sex The Sexual Response Cycle Sexual response cycle Excitement phase Plateau phase Orgasm Resolution phase Refractory period
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.
The Physiology of Sex Sexual Dysfunctions and Paraphilias Sexual Dysfunctions Erectile disorder Premature ejaculation Female orgasmic disorder Paraphilias Exhibitionism, fetishism, pedophilia
Sexual Dysfunction = a problem that consistently impairs sexual arousal or functioning.
The Physiology of Sex Hormones and Sexual Behavior Effects of hormones Development of sexual characteristics Activate sexual behavior Estrogen Testosterone
Estrogens = sex hormones, such as estradiol, secreted in greater amount by females than males and contributing to female sex characteristics. In nonhuman female mammals, estrogen levels peak during ovulation, promoting sexual receptivity.
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.
The Psychology of Sex External stimuli Imagined stimuli Dreams Sexual fantasies

Introduction Aristotle s social animal Need to belong affiliation need
The Benefits of Belonging Enhanced survival How belonging influences our thoughts and emotions Attachment Anxious attachment Insecure avoidant attachment
The Pain of Being Shut Out Ostracism Cyberostracism Anterior cingulate cortex Influences on behavior
Connecting and Social Networking Mobile Networks and Social Media Cell phones Texting and email Facebook and twitter
Connecting and Social Networking The Social Effects of Social Networking Have social networking sites made us more, or less, socially isolated? Does electronic communication stimulate healthy self-disclosure? Do social networking profiles and posts reflect people s actual personalities? Does social networking promote narcissism?
Cognition and Emotion Emotions Bodily arousal Expressive behaviors Conscious experience
Emotion = a response of the whole organism, involving (1) physiological arousal, (2) expressive behaviors, and (3) conscious experience.
Cognition and Emotion Historical Emotion Theories Common Sense theory James-Lange theory Cannon-Bard theory Lower spine injuries High spinal cord injury
James-Lange Theory = the theory that our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli.
Cannon-Bard Theory = the theory that an emotion-arousing stimulus simultaneously triggers (1) physiological responses and (2) the subjective experience of emotion.
Cognition and Emotion Cognition Can Define Emotion: Schachter and Singer Two-factor theory Schachter-Singer Spillover effect
Two-Factor Theory = the Schachter-Singer theory that to experience emotion one must (1) by physically aroused and (2) cognitively label the arousal.

The Effects of Facial Expressions Facial feedback effect Health psychology
Facial Feedback Effect = the tendency of facial muscle states to trigger corresponding feelings such as fear, anger, and happiness.
Health Psychology = a subfield of psychology that provides psychology's contribution to behavioral medicine.
Stress: Some Basic Concepts Stress Stress appraisal
Stress = the process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging.
Stress: Some Basic Concepts Stressors Things that Push Our Buttons Catastrophes Significant life changes Daily hassles
Stress: Some Basic Concepts The Stress Response System Selye s general adaptation syndrome (GAS) Alarm Resistance Exhaustion Tend-and-befriend
General Adaptation Syndrome (GAS) = Selye s concept of the body s adaptive response to stress in three phases alarm, resistance, exhausion.
Tend-and-Befriend Response = under stress, people (especially women) often provide support to others (tend) and bond with and seek support from others (befriend).
Stress: Some Basic Concepts The Stress Response System General Adaptation Syndrome
Introduction Psychophysiological illnesses Psychoneuroimmunology (PNI) Lymphocytes B lymphocytes T lymphocytes Macrophage Natural killer cells (NK cells)
Psychophysiological Illness = literally, mind-body illness; any stressrelated physical illness, such as hypertension and some headaches.
Psychoneuroimmunology = 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 the 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.
Stress and Susceptibility to Disease Stress and AIDS Stress and Cancer Stress and Heart Disease Coronary heart disease Type A Type B
Coronary Heart Disease = the clogging of the vessels that nourish the heart muscle; the leading cause of death in many developed countries.
Type A = Friedman and Rosenman s term for competitive, hard-driving, impatient, verbally aggressive, and anger-prone people.
Type B = Friedman and Rosenman s term for easygoing, relaxed people.
