Chapter 8 Emotion and Motivation What Is Emotion? Emotion – A four-part process consisting of physiological arousal, cognitive interpretation, subjective feelings, and behavioral expression What Do Our Emotions Do For Us? Emotions have evolved to help us respond to important situations and to convey our intentions to others The Evolution of Emotions Emotions have survival value and have been shaped by natural selection Individuals vary tremendously in emotional responsiveness Emotions are not entirely programmed by genetics Mrs. B. and the 7 Basic Emotions! Cultural Universals in Emotional Expressions Can’t remember those? Then how about this mnemonic device! A (anger) Dog (disgust) Fears (fear) His (happiness) Shadow (surprise) Cats (contempt) Squirrels (sadness) •There are, however, huge cultural differences in the context and intensity of emotional displays Cultural Universals in Emotional Expression Display rules – Permissible ways of displaying emotions in a particular society The Emotion Wheel Where Do Our Emotions Come From? The discovery of two distinct brain pathways for emotional arousal has clarified the connections among the many biological structures involved in emotion and has offered solutions to many of the longstanding issues in the psychology of emotion The Neuroscience of Emotion The biological mechanisms at work behind our emotions include: • • • • • The limbic system The reticular formation The cerebral cortex The autonomic nervous system Hormones JamesLange theory CannonBard theory Twofactor theory Stimulus: Big Bad Wolf Stimulus: Big Bad Wolf Stimulus: Big Bad Wolf Physiological arousal trembling increased heart rate Emotion fear Physiological arousal trembling increased heart rate Emotion fear Physiological arousal trembling increased heart rate Cognitive interpretation “Wolves scare me!” Emotion fear Psychological Theories of Emotion Cognitive appraisal theory – Theory that individuals decide on an appropriate emotion following the event Opponent-process theory – Theory that emotions have pairs; when one is triggered the other is suppressed Arousal, Performance, and the Inverted “U Describes the relationship between arousal and The Inverted “U” Function – Describes the performance; both low and high levels of arousal relationship between arousal and performance. produce lower performance than does a moderate level of arousal Copyright © Allyn & Bacon 2007 Arousal, Performance, and the Inverted “U” Sensation seekers – Individuals who have a biological need for higher levels of stimulation than do other people How Much Control Do We Have Over Our Emotions? Although emotional responses are not always consciously regulated, we can learn to control them Developing Emotional Intelligence Emotional intelligence – Ability to understand and control emotional responses Emotional control can be achieved by learning Detecting Deception People can also control their emotions to deceive Do “lie detectors” really work? Polygraph – Device that records the graphs of many measures of physical arousal; often called a “lie detector” really an arousal detector Motivation: What Makes Us Act as We Do? Motivation takes many forms, but all involve inferred mental processes that select and direct our behavior Motivation: What Makes Us Act as We Do? Motivation – All processes involved in starting, directing, and maintaining physical and psychological activities How Psychologists Use the Concept of Motivation Motivation • Connects observable behavior to internal states • Accounts for variability in behavior • Explains perseverance despite adversity • Relates biology to behavior Types of Motivation Drive – Biologically instigated motivation Motive – Internal mechanism that directs behavior (often used to describe motivations that are learned, rather that biologically based) Types of Motivation Intrinsic motivation – Desire to engage in an activity for its own sake Extrinsic motivation – Desire to engage in an activity to achieve an external consequence (e.g. a reward) Rewards Can Sometimes Squelch Motivation Overjustification – The process by which extrinsic rewards can sometimes displace internal motivation, as when a child receives money for playing video games Types of Motivation Conscious motivation – Having the desire to engage in an activity and being aware of the desire Unconscious motivation – Having a desire to engage in an activity but being consciously unaware of the desire Theories of Motivation Instinct theory – View that certain behaviors are determined by innate factors Fixed-action patterns – Genetically based behaviors, seen across a species, that can be set off by a specific stimulus Theories of Motivation Drive theory – View that a biological need (an imbalance that threatens survival) produces drive Drive Reduction Theory – An action that reduces the drive Homeostasis – The body’s tendency to maintain a biologically balanced condition Theories of Motivation Locus of control – An individual’s sense of where his or her life influences originate–internally or externally Maslow’s Humanistic Theory Hierarchy of needs – The notion that needs occur in priority order, with the biological needs as the most basic How Are Achievement, Hunger, and Sex Alike? Different? No single theory accounts for all forms of motivation, because each motive involves its own mix of biological, mental, behavioral, and social/cultural influences Measuring the Need for Achievement Projection – Process by which people attribute their own unconscious motives to other people or objects Need for achievement (n Ach) – Mental state that produces a psychological motive to excel or reach some goal A Cross-Cultural Perspective on Achievement Individualism – View that places a high value on individual achievement and distinction Collectivism – View that values group loyalty and pride over individual distinction Hunger Motivation The multiple-systems approach to hunger Hunger Motivation The multiple-systems approach to hunger • Set point – Refers to the tendency of the body to maintain a certain level of body fat and body weight • Lateral Hypothalamus • Ventromedial Hypothalamus • Eating Disorders • Weight control is a complex issue with no simple answers Thirst and Pain Volumetric thirst – A drop in extracellular fluid levels Osmotic thirst – A drop in intracellular fluid levels The Scientific Study of Sexuality Kinsey interviewed 17,000 Americans concerning their sexual behavior Masters and Johnson Sexual response cycle – Four-stage sequence of arousal, plateau, orgasm, and resolution occurring in both men and women Phases of Human Sexual Response Sexual Motivation Virtually any stimulus that becomes associated with genital touch and orgasm can become a conditioned stimulus that motivates sexual activity Sexual scripts – Socially learned ways of responding in sexual situations Both learning and genetics affect our sexual behaviors The Origins of Sexual Orientation Sexual orientation – One’s erotic attraction toward members of the same sex, the opposite sex, or both sexes Motives in Conflict Approach-approach conflict – A conflict in which one must choose between two equally attractive options Approach-avoidance conflict – A conflict in which there are both appealing and negative aspects to the decision to be made Motives in Conflict Avoidance-avoidance conflict – A conflict in which one must choose between two equally unattractive options Multiple approach-avoidance conflict – A conflict in which one must choose between options that have both many attractive and many negative aspects How and Why Do We Experience Stress? The human stress response to perceived threat activates thoughts, feelings, behaviors, and physiological arousal that normally promote adaptation and survival Stress and Stressors Stress – A physical and mental response to a challenging or threatening situation Stressor – a stressful stimulus, a condition demanding adaptation A Model of Stress Traumatic Stressors Traumatic stressor – a situation that threatens one’s physical safety, arousing feelings of feel, horror, or helplessness Catastrophe Cohen and Ahearn identified five stages that occur in the wake of natural disasters • • • • • Psychic numbness Automatic action Communal effort Letdown Recovery Posttraumatic Stress Posttraumatic stress disorder – delayed stress reaction in which an individual involuntarily re-experiences emotional, cognitive, and behavioral aspects of past trauma The Physical Stress Response Acute stress – A temporary pattern of arousal caused by a stressor with a clear onset and offset Chronic stress – A continuous state of stressful arousal persisting over time The Physical Stress Response Fight-or-flight response – A sequence of internal processes that prepares the organism for struggle or escape Tend-and-befriend model – stress response model proposing that females are biologically predisposed to respond to stress by nurturing and protecting offspring and seeking social support The Physical Stress Response General adaptation syndrome (GAS) – A pattern of general physical responses that takes essentially the same form in responding to any serious chronic stressor The General Adaptation Syndrome Alarm reaction Resistance – the body – the body seems to adapt mobilizes it’s to the resources to presence of cope with a the stressor stressor Level of normal resistance Alarm Reaction Exhaustion – the body depletes it’s resources Successful Resistance Illness/death Resistance Exhaustion Stress and the Immune System Immune system – bodily organs and responses that protect the body from foreign substances and threats Stress and the Immune System Psychoneuroimmunology – Multidisciplinary field that studies the influence of mental states on the immune system Cytokines – Hormone-like chemicals facilitating communication between brain and immune system Personality and Stress Type A – behavior pattern characterized by intense, angry, competitive, or perfectionistic responses to challenging situations Type B – behavior pattern characterized by a relaxed, unstressed approach to life Psychological Responses to Stress Learned helplessness – Pattern of not responding to noxious stimuli after an organism learns that its behavior has no effect Psychological Responses to Stress Resilience – Capacity to adapt, achieve well-being, and cope with stress, in spite of serious threats to development Motivating Yourself Flow – An intense focus on an activity, accompanied by increased creativity and near-ecstatic feelings Involves intrinsic motivation
