THEORIES CH 1. Motivation ○ Energy + Direction Self Determination Theory ○ Extrinsic motivation can’t explain all behavior; intrinsic motivation drives much of human behavior Autonomy (choose own path/behavior), competence (skills/mastery), relatedness (connected socially) ○ Extrinsic/Intrinsic on continuum Regulatory Focus Theory ○ Motivation varies on outcome being pursued approach/promoting: working towards something avoiding/preventing: working to avert something Not mutually exclusive Common Sense View ○ Event -> Feeling -> Behavior James-Lange Theory ○ Emotions based on sensations from muscles/organs reflected on body's reaction to certain situations Event -> Physiological Changes & Behavior -> Feeling ○ Revised (1894) Event -> APPRAISAL -> Physiological Changes & Behavior -> Feeling Appraisal: subjective interpretation of what stimulus means for concern Plutchik ○ Emotions are functional, quickly and efficiently facilitating actions that affect the world ○ Emotions are responses/reactions to object and events in environment ○ Emotions must be inferred than observed Four aspects Appraisal Feeling Physiological changes Behavior ○ NOT LIKE A SQUARE Core affect ○ Subjective feeling as defining aspect of emotion ○ Non-specific arousal ○ Event may cause valence and arousal but not necessary Event -> Valence & Physiological Arousal -> Feeling ○ The Circumplex Model (Russell, 2003) Emotional feelings form a circle defined by dimensions of pleasantness and arousal Not possible to feel strong positive and negative emotions The Evaluative Space Model ○ Dimensions of positive and negative activation Independent of each other ○ Arousal is built-in High +/- is high arousal/activation ○ Circles are similar but rotated differently Basic/Discrete Theory ○ Event -> Appraisal -> Emotion -> Observable Behavior ○ 3 propositions Each emotion thought to serve a district function Serve to coordinate individual aspects of emotion to produce package of responses to respond to situation The categories reflect distinction among natural occurring categories of human psychological experience Some categories should be inherent in human nature despite culture Component Process Model ○ Event -> Appraisals -> Emotion ○ People interpet environment using ALL-PURPOSE appraisals NOT CATEGORICAL appraisals ○ Each appraisal has independent effects Combined effects across appraisal produce emotion Psychological Construction (Barrett, 2013) ○ Event -> Valence & Arousal -> Feeling & Appraisals, Cogn. Changes, Action Tendencies, Observable Behavior ○ Different aspects of emotion are LOOSELY correlated ○ Emotion categories are LEARNED concepts Closely aligned to Schacter-Singer ○ Emotional experiences are created from psychological construction Schacter & Singer (1962) ○ Confusing results ○ Words and concepts used to describe emotions are learned and based on what we think we’re supposed to feel at the time CULTURE CH 3. Cultures are ways of interpreting, understanding, and explaining what’s going on in the world Sadness and pe’a pe’a (1973) ○ Sadness: loss/absence of loved one ○ Pe’a pe’a: infection, illness, or overwork Loss of energy, withdrawn, decreases activity, downcast expression Swidler (2001) ○ Hollywood Love ○ Prosaic Love Litost (Czech): torment from insight into one’s miserable self Schadenfreude (German): enjoyment of another’s suffering Liget (Ilongot): positive, socially encouraged response to insult or injury like a successful hunt, celebration, death of a loved one Amae (Japanese): pleasurable dependence on another, being taken care of Hyper vs. Hypo-cognized emotions ○ Hyper: culture has an elaborate network of associations and distinction, leading to increased vocabulary ○ Hypo: culture and language have little cognitive elaboration/detail Individualism vs. Collectivism ○ Western (Individual) and Eastern (Collective) Power Distance ○ Vertical: attend closely to social hierarchy, encouraging emotions and behaviors that respect status differences ○ Horizontal: typically minimize attention to status differences EMOTION AND BRAIN CH 6. Amygdala ○ Small, almond shaped structure in EACH temporal lobe ○ Receives input from sense ○ Damage Klüver-Bucy Syndrome (in animals): pattern of emotional changes with removal of both anterior temporal lobes and amygdalae Urbach-Wiethe Disease (in humans): calcium damage to amygdalae Fearless behavior, panic induced by suffocation ○ Fear Conditioning (1990) Lesions to amygdala showed weaker fear conditioned responses ○ Functions of memory (Phelps, 2004-5) Directs attention toward stimuli with emotional implications Facilitates activity in hippocampus (adjacent) that stores vivid memories of personal experience Reward Circuit ○ Nucleus accumbens and ventral tegmental area (NA) primary input strongly respond to rewarding stimuli Sometimes responds to punishment Dopamine is primary neurotransmitter Wanting/Liking ○ Stimulus is perceived as pleasant based on person’s preference ○ 3 microcircuits One active during anticipation of and movement toward likely reward Another while reward is being consumed Last involved in learning to predict future rewards and punishments Hypothalamus ○ Below thalamus, above brain stem ○ Body’s thermostat, regulates physiological variables and behavior to maintain homeostasis ○ When stressed, triggers pituitary to release cortisol ○ Collects sensory information from outside the body Homeostasis ○ Body’s regulation of temperature, hydration, oxygen levels, sugar levels, salt levels, etc. within a healthy range Prefrontal ○ Front of motor and premotor areas ○ Active in cognitive functions Planning, working memory, and inhibition of impulses ○ Activated when using cognitive appraisal to reduce emotional intensity ○ Inhibits activation of amygdala Amygdala communicates with prefrontal cortex, informing of possible emotional consequences of a decision and enabling selecting of a good outcome ○ Gage (1848) Less polite, used more profane language ○ Elliot Lack of emotional reactivity Dopamine ○ Ventral tegmental area to nucleus accumbens active after unpredicted reward and decreases when reward failed to appear Attention increases and facilitates learning about how to get reward ○ Less activated in depression Pharmaceutical treatment increases ○ Important in cognitive operation in frontal lobes ○ Antipsychotic drugs block dopamine synapses ○ Stimulant drugs increase in dopamine receptor activity in NA Drug abuse increases activity but sometimes indirectly blocks something that inhibits its release Serotonin ○ Involved in sleep, memory, appetite control, nausea ○ SSRIs used to treat depression Oxytocin ○ Uterine contractions, milk extraction in breast feeding ○ Increase during sexual arousal and orgasm ○ Nasal spray elicits Men more attracted to their partner but not other women Willingness to trust but effects inconsistent Increases attention to social cues, magnifies inclinations already felt Meta-Analyses ○ Lindquist (2012) Brain structure Tested selective activation of hypothesized structures Result: different emotions CANNOT be distinguished ○ Vytal & Hamann (2012) Pattern of brain activity Examined patterns of activation across every voxel and identified regions that are consistently more active in one emotion that in others Result: different emotions CAN be distinguished NERVOUS SYSTEM CH. 7 Autonomic Nervous System ○ Set of neurons communicating between CNS and visceral organs (heart, lungs, arteries, stomach, intestines, genitals, and sweat glands) ○ Important in maintaining homeostasis ○ Two branches Sympathetic: fight or flight Increased heart rate, breathing rate, sweating, and blood flow to muscles Inhibits digestion Pupil dilation Decreased blood flow to stomach and intestines Parasympathetic: rest and digest Maintenance and growth activities Decreases heart rate and slower breathing Increased salivation and digestive system Insulin release promotes storage of energy in liver and fatty tissue Facilitates sexual arousal, dilates vessels leading to genitals Hormones and Endocrine System ○ Control of interior body ○ Insulin released from pancreas, cells take in more glucose for energy ○ Growth hormone (pituitary) cell reproduction ○ Cortisol Increase in blood sugar Encourages live to release glucose Promotes breakdown of muscles and fat to produce more glucose Long-term promotes storage of fat (waist) Increased blood pressure Cortisol and Mornings ○ Peaks after waking and declines throughout day ○ Smaller waking cortisol linked to depression, economic hardship, and severe stress during childhood ○ Larger waking cortisol linked to negative daily emotions, depression Blunted Responses to stressful experiences later in the day, some cortisol response is healthy Seen in children who’ve been abused/bullied or who’re experiencing chronic and adults who experienced greater stress as children In puberty, linked to higher levels of early life stress Lack of responsiveness suggests under severe, ongoing stress, people’s bodies may begin giving up responding to challenging situations Estrogen ○ Mood-enhancing; sharp drops linked to depression ○ Complex relationship between mood Mood responds to change in levels rather than absolute levels like puberty and menopause Testosterone ○ Sexual motivation, mood-enhancing effects (minor depression with low TE) ○ Increases aggression, cortisol decreases High ratio of TE to cortisol correlates with increased aggressive behavior and increases risk-taking behavior Measures ○ Heart rate (beats per min) and Cardiac interbeat interval (time between beats) ○ Blood pressure (volume of blood in each heartbeat) Systolic: pressure of blood on arteries while ventricles contract Diastolic: pressure while ventricles are relaxed, between beats Mean arterial: average pressure across systole, diastole ○ Respiration rate ○ Electrodermal activity (increase in speed of electrical conductivity by the skin due to increased sweat) ○ Cardiac pre-ejection period (time in ms between onset of ventricular contraction, opening of aortic valve ○ Respiratory sinus arrhythmia (difference in respiration rate while inhaling vs exhaling) Pure Autonomic Failure ○ ANS ceases to influence the body; people report feeling emotions less intensely Incurable, unknown causes, middle age Locked In Syndrome ○ Lose almost all output from the brain to the muscles and ANS Still feel sensations like touch and pressure ○ Caused by stroke or damage to part of the brainstem ○ Key areas of the pons and medulla are damaged where axons travel from the brain to spinal cord ○ Person retains ability for eye movement while completely paralyzed Intellectually alert and capable of surviving for several years Effects of cortisol General Adaptation Syndrome ○ Alarm: brief period of high arousal Mediated by sympathetic nervous system, hormones adrenaline, cortisol ○ Resistance: period of prolonged, moderate arousal in response to some stressor Mediated primarily by endocrine system (cortisol continues) ○ Exhaustion: reaction to prolonged stressor characterized by weakness, fatigue, loss of appetite, and lack of interest
