1 Psychology Chapter 12 Study Guide Emotion is a full body/mind/behavior response to a situation Theories of emotion James-Lange theory body before thoughts Cannon-Bard theory body with thoughts Singer-Shater theory (two factor theory) body + thoughts, then label Zajonc-LeDoux-Lazanes theory body/brain without conscious thoughts James-Lange States that emotion is our conscious awareness of our physiological responses to stimulus Our body arousal happens fast and then the cognitive awareness Cannon-Bard theory Asserts that we have a conscious cognitive experience of an emotion at the same time our body is responding not afterward Human body responses run parallel to the cognitive responses rather than causing them Emotions are not just a separate mental experience when our body responses are blocked emotions do not feel as intense Our cognitions influence our emotions in many ways including our interpretation of stimuli Schachter-Singer Two factor theory Suggests that emotions do not exist until we add a label to whatever body sensations we are feeling Spill over affect your mood affected by others (study = adrenaline test) Highlighted the role of appraisal Zajonc-LeDoux-Lazanes Some emotional reactions especially fears likes and dislikes develop in a low road to the brain skipping conscious thought Amygdala response without being aware of image/reaction Appraisal effects emotion Schachter and singer highlighted the role of appraisal being consciously experienced emotions Lazurus: even in emotional responses that operate without consciousness thought to down cognitive functions such as appraisal of stimuli can be involved Autonomic nervous system The physiological arousal felt during various emotions is orchestrated by the sympathetic nervous system which triggers activity and changes in various organs Ater parasympathetic nervous system calms down the body Abby Carroll 1

2 Embodied emotion Hard to see difference in emotion from tracking heart rate breathing and perspiration Large overlap in patterns of brain activity across emotions Small differences, fear triggers more amygdala activity than anger does General brain pattern hemispheric difference Positive approach emotions (joy love goal-seeking) correlate with left hemispheric activity Negative withdrawal emotions (disgust, fear, anger, depression) correlate with right hemispheric activity Emotions of others Emotion content in eyes and faces Introverts are better at detecting emotions Extroverts emotions are easier to read Primed to detect negative emotions quickly, even negative emotion words Those who are abused are biased to see fearful faces as angry Lies and fakes Polygraphs (detecting physiological arousal) fail sometimes at correctly identifying when people are lying Visible signs of lying eye blinks decrease ad other social movement change Real smile- involuntary muscle around the eyes Gender and emotional expression and detection Women have greater and more complex emotional expression Women are more skilled at detecting emotions Overgeneralization people tend to attribute women s emotionality to their dispositions attribute more to circumstances Some emotions more male (anger) Universal emotions Some universally understood facial expressions People more accurately identify emotions from their own culture Origins facial expressions People who are blind form birth show same facial expressions as sighted people origins of expressions are genetic Face Facial dieback effect facial position and muscle position can alter which emotion that we feel People s faces were moved in frowning and smiling positions means that they had a change in mood Middle finger up is associated with hostility, thumbs up associated with happiness Abby Carroll 2

3 Anger Flash anger = energy Persistent anger causes more harm Catharsis release refers to the idea of reducing anger by releasing it may reinforce anger Happiness A mood, attitude, social phenomenon, cognitive function stay hopeful and motivated, and connected to others Feel good do good phenomenon: when in a good mood we do more good for others doing good, feels good Levels of happiness vary over a week/day Money can make people happy, if it uplifts them from extreme poverty Have an increase in money, spend more money Adaptation level phenomenon when our wealth of other life conditions improve we are happier to our past conditions however then we adapt to form a normal level, people need another boost to feel the same satisfaction Loss and disability not a permanent decrease in happiness Relative derivation feeling worse off by comparing yourself to people who are doing better Stress Stressor- an overall event or condition which we view as threatening challenging or overwhelming Appraisal deciding whether something is a stressor Stress reaction refers to any emotional and physical responses to the stressor such as rapid heartbeat or an increase in cortisol levels Stress refers to the process apprising and responding to events we view to be threatening and challenging Component of stress Process stressor level/conditions, cognitive appraisal, body response, coping strategies Appraisal choosing how to view a situation Few conditions inherently and universally stressful (extreme chronic physical threats/challenges) Harms and benefits Brief experience beneficial Improving immune system Motivating action Focusing priorities Abby Carroll 3

4 Feeling engages energized and satisfied Providing challenges encourage growth knowledge self-esteem Prolonged stress Mental physical coping systems become overwhelmed and fail Immune function decreases Stressors Spectrum of levels of intensity and persistence of stressors Refer to the events and conditions that trigger our stress response because they are perceived as overwhelmingly challenging threatening and or harmful Four categories Catastrophes Life changes Chronic daily hassles Low social status/power Catastrophes Appraisal not really needed most people agree that the event is harmful/overwhelming Can be one single event or chronic/harmful conditions Short term effects increased heart attacks on day of the event Long term effects - depression nightmares anxiety flashbacks Bonding - both the trauma and recovery shared with others Major life changes Even supposedly happy life changes (marriage, college, new job, birth/adoption of a child) can bring increased challenge and stress Change is often challenging New roles and priorities new tasks can put a strain on coping resources Chronic daily differences Too many tasks too little time little control Bullied, poverty, oppressive, political conditions Body response to stress system General adaption syndrome (GAS) Alarm reaction Phase one: fight/flight sympathetic nervous system responds reducing pain increasing heart rate core of the adrenal glands produces norepinephrine and epinephrine (adrenalin) identified by Walter Cannon ( ) Resistance Phase 2: brain sends signals to the outer part of the adrenal glands to produce cortisol and other stress hormones focus on adopting copint strategies and resisting defeat by the stressor Abby Carroll 4

5 Exhaustion Phase three Prolonged stress GAS works well to single exposures to stress Too much phase three lads to physical deterioration and premature aging Productions new neurons decline New circuits brain break down DNA telomeres (chromosome tips) shorten and cells lose the ability to divide and then die and tissue stops regenerating leading to early aging and death Male/female response Women tend and befriend: nurture themselves/others bond together Bonding hormone oxytocin Women behavioral/neurological signs are more empathetic under stress Men socially withdrawal and turn to alcohol Men are more likely to be aggressive Behavior and brain show less empathy and less turning to others under stress Stress illness relationship New field in psychology: psychoneuroimmunology the study of how interacting psychological neural and endocrine process affect health Psychologists no longer use the term psychosomatic because it has come to mean an imagined illness Psychophysiological illness a real illness caused in part by psychological factors such as stress Psychological appraisal thoughts feelings Neurological factors brain signals engaging the stress response system Immunology stress hormone exposure which suppresses the immune system Stressors appraisal thoughts feelings brain signals hormonal action immune suppression risk of illness Stress AIDS cancer AIDS Acquired Immune Deficiency Syndrome Cant acquire through stress Stress response suppresses immune response, exposure to stress obviously worsens development of AIDS in those exposed to HIV Decrease in stress slows progress in AIDS Cancer link to stress isn t really clear May worsen body s defenses against replication Heat disease and stress Abby Carroll 5

6 Coronary heart/artery disease the blood vessels that provide oxygen and nutrients to the heart muscle itself becomes clogged narrowed and closed Biological genetic predisposition to high blood pressure and cholesterol Behavioral: smoking inactivity high fat diet Psychological: chronic stress personality styles personality styles that worsen experience of stress Type A personality Type A personality impatient verbally aggressive always pushing themselves and others Type B more relaxed and go with the flow One study people who had heart attacks were only type A Pessimism and heart disease Refers to the assumption that negative outcomes will happen and often facing them by complaining and giving up Pessimistic men more likely heart disease within 10 years than optimists Depression and heart disease 2 problems may both be caused by stress Intervening variable excessive inflammation Health consequences of stress Stress hormone cortisol helps bodies respond to brief stress Chronically high cortisol levels damage the body Promote health Address stressors Soothe emotions Increase ones sense cortisol over stressors Exchange optimism for pessimism Social support Aerobic exercise Relax and meditate Participation communities of faith Alternative medicine Cope stress Problem focusing stress means reducing stressors such as by taking on a difficult project Risk: magnifying emotional distress especially by tying to change something that s difficult to change (person s traits) Emotion focused coping means reducing the emotional impact of stress by getting support comfort and perspective from others Risk ignoring the problem Abby Carroll 6
