McElhaney AP Outline  VIII. Motivation and Emotion (7–9%)  Biological Bases  Theories of Motivation  Instinct, Drive Reduction, Optimal Arousal, Incentive Theories  Hunger- Eating Disorders; Thirst, Sex, Social Cultural Factors, Sexual Orientation and Pain  Social Motives, Achievement Motivation,  Theories of Emotion, James-Lange Theory, Cannon-Cognitive Theory; Characteristics, Biology of Emotion, Emotional Expressions  Stress Basics of Motivation  Our behavior is energized and directed by motives and emotions  There are links between motives and emotions  Basic motives- Hunger-thirst are monitored within the brain  Activities/motives are related to needs for stimulation and to maintain arousal Definition of Motivation:  The factors that influence initiation, direction, intensity + persistence of behavior  Why do we do what we do?  Behavior is based partly on the desire to feel certain emotions.  How is motivation exemplified by Hunger, sexual desire and Need for Achievement?  effects emotion example- hunger and irritability  Motivation Motive:  A reason or purpose that provides a single explanation for diverse behaviors. Some psychologists think of motivation as an “intervening variable” Intervening variable is something that is used to explain the relationship between environmental stimuli and behavioral responses.  Sources of motivation: 4 basic categories Biological Factors- Autonomic Nervous System 2. Emotional Factors- panic, fear, anger, love, hatred 3. Cognitive Factors- perceptions, beliefs, expectations 4. Social Factors – other people, influence from parents, friends, teachers, TV, Siblings…Factors1. Theories of Motivation (web)  Instinct- Evolution=genetic predispostion  Drive Reduction -biological, focus on how our inner pushes and external pulls interact  Optimal Arousal- finding the right level of stimulation  Maslow- Hierarchy of Needs- describes how some of our needs take priority Basic Model of Motivation  Dynamics of behavior in the way actions are:  Initiated  Sustained  Directed  Terminated Example of Food Seeking Initiated by bodily need  Search was sustained  Action directed by possible sources  Terminated by attained goal  The Model (Motives)  Motivational Activities- begin with needs  Need is an internal deficiency Needs cause - Drive= energized state that facilitates a need  Drives --activate a response = an action or series of actions to attain a goal  Goals are targets of motivational behavior  Need Drive Need reduction Goal response Difference between Needs and Drives Need - A state of deficiency  Drives - Psychological states activated to satisfy needs, Often associated with some kind of arousal, Increased physiological and/or autonomic activity,  For many biological needs, drive satisfaction is regulated by homeostatic mechanisms and  are stronger than drives  External Stimuli  Motivated behavior can be energized by the pull of External Stimuli  And push of internal needs Action is a Mix Internal needs and External Incentives  (types of conflicts are associated)   Incentive value of goals helps us understand motives that don’t come from internal needs  Example success = status-approval Types of Motives: 3 Categories 1. Primary-(innate)  Based on biological needs  Must be met for survival  Hunger, thirst, pain avoidance  Air, sleep  Elimination of waste  2. Stimulus Motives (not necessarily for survival)        Need for stimulation Need for information Activity Curiosity Exploration Manipulation Physical contact         Not necessary for survival Stimulus Drives= reflect need for: Need for stimulation Need for information Activity – curiosity Explorationmanipulation Physical contact Sensory input (sex) 3. Secondary Motives (learned motives) Learned needs or drives and goals  Making music  Competing  Learned needs for power        For affiliation Status Security Approval Achievement Fear + Aggression are learned Drive Reduction Theory Physiological need creates an arousal state that drives an organism to reduce a need.  Eating/drinking example  As a need  increases  A drive increases  (a drive is an aroused motivated state)  Instinct theory Unlearned  Evolutionary psych  Genes predispose species typical behavior  Example:  Rooting reflexes  , aggression, (maybe Phobia)  Helping behaviors  Romantic attractions, mate selection  Arousal Theory  Says ideal levels of activation exist for various activities  Arousal refers to activation of body + nervous system     [email protected] = no arousal=death Low during sleep or boredom Moderate during daily activities High at times of excitement, emotion, panic, fear and anxiety Levels of Arousal  We perform best when we have a Moderate level of Arousal     Not too passive/not too anxious=Performanc e Inverted U Function Says at low levels of arousal=decrease performance More arousal= improved performance Levels of Arousal 2  Ideal level arousal depends on complexity of the task Simple tasks--Best for arousal to be high Complex tasks  best for low/moderate arousal Yerkes-Dodson Law Sensation Seekers People learn to seek particular levels of arousal  Sensation seeking scale+ Thrill +adventure seeking   Experience seeking  Disinhibition  Boredom Susceptibility  Primary Motive is Homeostasis Biological needs- direct much of our behavior  Are used to maintain body balance= Homeostasis  Hunger (motive) is a regular cycle each day  Good example of how internal and external factors direct behavior  Liver affects hunger  Hunger 2  Stomach size some indication of hunger  Glucose- level in blood and  hypoglycemia = low blood sugar level  Feeling of hunger causes stomach contractions sends nerves signal to brain  desire to eat  Liver PainDrive to avoid pain=episodic  Takes place at certain episodes when body is or is about to be damaged   Prompts us to avoid pain  Pain tolerance- is learned- raise of lower tolerance Brian Mechanisms  There are many parts of brain associated with motivation Hypothalamus  does regulate motivation and emotion  Thirst, hunger, sexual behavior  Is sensitive to sugar in the blood  Receives neural messages from liver and stomach  One part signals hunger =feeding system ○ Which initiates eating  Lateral hypothalamus- (hunger feelings)  When electrified causes animals to eat  Secretes Appetite stimulating hormones  If destroyed = no eating  Marijuana-”Mary-Jane” causes a hypothalamic response= “Munchies” Ventro-Medial Hypothalamus Part of Hypothalamus relates directly to Satiety (fullness) feelings= stop mechanism  If destroyed = overeating  Appetite surprising hormones  (Bottom medium part of the hypothalamus)  Paraventricular Nucleus of Hypothalamus Affects hunger= helps keep blood sugar level steady  Both- starts and stops eating  Sensitive to Neuropeptide Y (NPY)   Large amount = hunger Glucagon -Like Peptide 1 (GLP1)  Causes eating to cease  Released by intestines  After eating a meal  In blood then to brain  10 minutes after eating- (eat slow = eat less) Set Point- Thermostat  Low weight body increases appetite     When fat levels rise Leptin- Fat cells release-tells brain to stop eating. Leptin circulates at levels directly proportional to body fat. It enters the central nervous system in proportion to its plasma concentration. Its receptors are found in brain neurons involved in regulating energy intake and expenditure.  It controls food intake and energy expenditure by acting on receptors in the mediobasal hypothalamus.[15]   The body is homeostatic when we are at the set point and then it is activated to reach the set point when we fall below. Blood Chemistry    hunger arousing Ghrelin- secreted by empty stomach hormone, signals brain Orexin- hormone secreted by hypothalamus    Insulin- hormone secreted by pancreas controls blood glucose Leptin- protein in hormone secreted by fat cells increases metabolism and decreases hunger Pyy- digetstive tract hormone send satiety signals to brain Write a synthesis paragraph explaining how all of these mechanisms should be understood. (In other words, what do we learn about eating motivation from these mechanisms?) Hypoglycemia Liver affects hunger-How? Hypothalamus: Lateral Hypothalamus Para-ventricular Hypothalamus Brain Mechanisms: Lateral Hypothalamus Ventro-Medial Hypothalamus Glucagon like peptide 1 Set Point Leptin- Taste Aversion  Associated with nausea  Classical conditioning  Biological tendency- associate food with sickness  Protective Eating Disorders  Anorexia Nervosa  Adolescent Females     <5-10% male> Severe Dieting Compulsive attempt to lose weight Do not seek or desire food 1 in 20 die of malnutrition  Bulimia Nervosa  Gorge on food then vomit  Take laxatives to avoid weight gain Causes of Bulimia Anorexia  Women dissatisfied with bodies (Perception)  Distorted view of themselves  “They think they’re fat, exaggerated fears of becoming fat.”  Distorted Messages from media (Social)  Compulsion- comparing to models  Distorted body image   Perfect daughter control issues Shame, guilt, self contempt, anxiety (Abnormal) Treatment of Eating Disorders  Medical diet  Behavioral Counseling- self monitoring of food intake  Extinction training (to end the learned behavior) urge to vomit  Cognitive approach Change the thinking patterns & belief system about weight + body image  Usually people need outside support and urging from family Sex Researchers       Kinsey 1940’s and 1950s used surveys to study sexual practices (Problem of Courtesy Bias) Masters and Johnson 1966, in a laboratory, measured sexual arousal and behavior Wanted to solve sexual dysfunctions Measured over 8000 sexual cycles Volunteers received natural and artificial stimulation problem -conclusions, may not be representative of larger population (limited population sample) Sex “Drive”   Sex Drive= one’s motivation to engage in sexual behavior Mammals- femalehormone- Estrus = “Heat”    Male animals Ready to mate sex drive= aroused by behavior + scent of receptive female Human Sex “Drive” really Motivation  Non-Homeostatic- it works independent of bodily need Sex motivation in men is related to amount of Androgens= male hormone  Produced by testes  (puberty- increases supply of androgens)  Human Sex Motivation  Human sex Motivation can be aroused at anytime  Sexual  Sex activity- does not prevent sexual desire drive can be aroused + Reduced  “The Coolidge Effect” Habituation  Male sex drive can be aroused repeatedly with new sexual partners.  Biology of Sex:       Master’s and Johnson identified Sexual Response Cycle: The Pattern of physiological arousal during + after Men Women sexual arousal Both men and women Resolution Excitement Plateau Orgasm  (evolutionary in women to facilitate conception)   Resolution Men have 1 pattern  Resolution=relaxation  Refractory= men unresponsive  (Women don’t have this they are capable of repeating cycle) Sex Hormones:           Estrogens Progestins-ProgesteroneAndrogens = Testosterone Each Hormone flows in blood of each Male and Female Average man has more androgens Women have more Estrogen + Progesterone Organizational Effects on Brain: Permanent changes that alter brain’s response Occur at birth Create male and female patterns     Sexually Dimorphic (sex differences) Area of Hypothalamus Rising level of sex hormone in puberty Women- Estrogen + Androgens (ovaries and testes- secrete) Hormones motivate us   Activational Effects: Activates behavior  Effects behavior when hormone is in blood stream  Associated with fertility Female is sexually receptive = estrogen level high  Peaks at ovulation    Stimulate sexual interest (androgens and estrogens in female) (androgens only in males)     Sexual desire rises at ovulation Ovulation is one part of the female menstrual cycle whereby a mature ovarian follicle (part of the ovary) discharges an egg (also known as an ovum, oocyte, or female gamete). It is during this process that the egg travels down the fallopian tube where it may be met by a sperm and become fertilized. Women to mates Day 14 (since the last period) Every 28 days Decrease in hormones = decrease in sex drive Ovulation Psychology of Sex  Sex is not a biological need 1. Similar to hunger Internal physical mechanism Excitatory response Cultural aspects 2. 3. 4. Men and women respond to external stimuli  Example: the amygdala more active in men  Learned behavior  Sexual models influence perceptions  Example of devaluing partners  Dreaming both male and female have sexual dreams  Habituation occurs  Social and Cultural Factors in Sexuality:  Learned Gender Roles- Differences   Men and porno MRI Study shows activity of amygdala + hypothalamus in men  Sexual Orientation:  Defined: A person’s enduring, emotional, romantic, or sexual attraction to others Hetero, Homo, Bi-sexual 1973 Homosexuality was dropped from the DSM Diagnostic and Statistical Manual (used for making diagnosis for abnormal behavior)   ○ ○ Dropped in china as a mental disorder 2001 Estimated 2-21 % of population is gay  What shapes sexual orientation?  • • • • •     Genes may influence sexual orientation. Identical twin studies show, 52% correlation one gay other one is too. Also, twins were raised apart. One reason too much hormone in utero May also be associated with increase in androgens and altered structure Gender Differences in sex Motivation Consistent Gender Differences:  Men tend to have stronger interest in and desire for sex than women  Women more likely than men to associate sexual activity with a committed relationship   Women with sexual dysfunction are greatly correlated to emotional relationships problems. University of Chicago Sex Survey:        Surveys found: People generally have sex = 1 per week, with a partner in stable relationship. Some a few times or not at all in the past year Average male had only 6 partners entire life Average female = lifetime 2 partners People in committed one partner relationships had the most frequent and satisfying sex Majority of heterosexual couples engaged in traditional intercourse   Nearly one quarter of U.S. women prefer to achieve sexual satisfaction without partners of either sex   Findings did not address pornography or sexual deviations, and sample was only in USA Circadian Rhythms  Internal Biological Clocks  24 hour cycle  Guide Body Activity Liver  Kidney  Blood Pressure  Endocrine Glands  Peak During Day Adrenaline is 3-5x higher Test Anxiety Pg 445 Learned Motives  We learn to pursue excellence  Reinforcers Praise money, success--affect goals and desires Opponent Process Theory  Richard Solomon (1980)  Explains learned motives  2 assumptions  1. Any reaction to a stimulus is followed by an opposite reaction – the “Opponent Process”  2. After repeated exposure to the same stimulus, the initial reaction weakens, and the opponent process becomes quicker and stronger”  Example drug addiction  “If a stimulus causes a strong emotion <Fear or Pleasure> an opposite emotion tends to occur when stimulus ends”  Stimulus of pain + Pain ends =relief Opponent Process Theory 2   Pleasure + Drug use – end of drug use= Pleasure ends – craving & discomfort develops In love + feel good when lover is present Take away lover = discomfort when they are not there  If stimulus is repeated- our response is habituated (gets weaker)    Emotional after affects get stronger with repetition (example- depression when drug use ends) Quiz: Opponent Process Theory Address the following:  Richard Solomon (1980)  Learned Motives  How does the Opponent Process theory relate to motivation?  What other connections to AP outline can we make?  Role of Stimulus  Give Examples  Social Motives  Success, money, possessions, status, love, approval, grades, power Acquired through conditioning + socialization  Due to learned needs  Need For Achievement (nAch)  A desire to meet an internal standard of excellence  People strive to do well- in any situation which evaluation takes place  People for high need for achievement enjoy challenges + chances to test abilities Need For Achievement (NACH)   Mclelland- could predict behavior of high and low achievers. Characteristics of:       People with high (nAch) don’t seek goals that are too easy Avoid goals that are too risky Complete difficult tasks to get grades Excel in occupations Work harder when they don’t do well Have Self-efficacy “According to Albert Bandura, selfefficacy is “the belief in one’s capabilities to organize and execute the courses of action required to manage prospective situations” (1995, p. 2). In other words, selfefficacy is a person’s belief in his or her ability to succeed in a particular situation. Bandura described these beliefs as determinants of how people think, behave, and feel (1994)” Achievers- Key To Success Benjamin Bloom  Identified via a study  Found  drive and determination = success  Achievers- Parents Support Success in Children   Tends to be learned in early childhood from parents Correlation between parent behavior + achievement motivation  Kids with low Achievement ○ Parents interfered with child difficulty ○ Parents became annoyed by lack of success of kid      Parents expose children to music, swimming, science, (ideas for fun) (Stimulating environment= more synapses) Talent is nurtured by dedication + hard work Support child’s special interest Emphasize doing one’s best at all times Coaching and encouraging practice Achievers- Self Confidence= people believe they can reach a goal     Set goals that are specific and challenging but attainable Visualize the steps you need to reach your goal Advance with small steps Get expert instruction  Find skilled models to emulate  Get support + encouragement  If you fail- regard it as a sign you need to try harder Self Confidence affects Motivation--- “Duh” Abraham Described a Hierarchy of Maslow Human needs Self actualizing = Full use of personal potential  Base of Pyramid= Necessary for survival  Pre-potent = Dominant over higher needs  Deficiency MotivesActivated by a lack of – food, water, security, love, esteem, or other basic need.  Growth needs Positive- life enhancing for personal growth.  Meta  needs- Higher needs, Tendency for selfactualization Maslow's Meta-Needs:  Wholeness (unity)  Perfection (balance and harmony)  Completion (ending)  Justice (fairness)  Richness (complexity)  Simplicity (essence)  Liveliness (spontaneity)≈        Beauty (rightness of form) Goodness (benevolence) Uniqueness (individuality) Playfulness (ease) Truth (reality) Autonomy (self-sufficiency) Meaningfulness (values). Meta Needs  We tend to move up to Meta needs  A person who meets survival needs then moves to meta needs if these are unfulfilled  They are in a “ Syndrome of Decay” Characterized by despair, apathy, and Alienation  Syndrome of decaywhen we cannot reach our higher other needs  Most people are concerned with esteem, love, security, but they don’t get much past that.  Intrinsic and Extrinsic Motives Intrinsic motivation- we act without any obvious external rewards. You are motivated on your own part.= high achievers  Extrinsic- external rewards enhance motivation- ex money, grades, approval  Emotion Defined  Emotion (defined) (emotion means to move)  Physiological arousal and changes in facial expression, gestures, posture, and subjective feelings  We are motivated by fear + Joy  Emotions cause us to action, to get enjoyment and action to avoid pain  Emotions are linked to adaptive behavior (recall we adapt to our environment, situation, by Attacking, fleeing, seeking, comfort, helping others, reproducing Emotions help solve + cause problems (stage freight)  Hate, anger, disgust, fear  Emotions disrupt behavior + relationships Connection Between Motivation and Emotion Motivation can intensify emotion.  Emotions can also create motivation.  People engage in activities that create or lead to emotions they desire  And or people are act to avoid emotion… also created motivation  Defining Characteristics of Emotion both Psychological and Physiological reactions to environment 1.  Emotion is Temporary-clear beginning and end  Mood lasts longer Emotional Experience can be positive and negative 2. ○ ○ Emotion Alters Thought processes 3. ○ ○ 4. Emotions can create motivationPeople engage in behaviors they think will lead to positive emotions Negative emotions = Narrow thinking Positive emotion = broad thinking Action is triggered by emotion AKA Action Tendency ○ Motivation to behave in certain ways ○ Negative –cause negative behaviors ○ Positive –causes positive behaviors 5. Emotions are Passions you feel ○ Emotions can be controlled somewhat through interpretation ○ Interpretation of experiences can impact emotional response ○ You cannot decide to experience joy or sorrow More Definitions of Emotion  1. Emotions are: Organized Psychological and Physiological reactions to changes ○ Subjective (Private) ○ Objective = Measurable  Characteristics: 1. 2. 3. 4. 5. 6. Emotions are temporary short duration Moods are longer lasting Emotions can be positive or negative or mixed Emotions can alter thought processes by directing attention Negative emotions = fear can narrow attention Positive- can widen our thinking (think broadly) Emotions can trigger action tendency or the motivation to behave in certain ways  Positive emotions joy, pride lead to playfulness and creativity and exploration of the environment:  Negative Emotions- sadness and fear promote withdrawal from threatening situations; anger might lead to actions that lead to revenge…  Subjective and Objective Aspects of Emotion Subjective Aspects are = Private processing  Are triggered by thoughts-then felt.   Objective Aspects of Emotion  Are expressive displays =smile—Frown  Physiological responses- heart rate Biology of Emotion Biology of Emotion: Involved in Generation of Emotion  Experience of Emotion     Autonomic Nervous System ANS is not connected to brain areas affecting consciousness  Arousal accompanies emotions          Sensory information alerts the brain to emotion- evoking situation Through the thalamus Hippocampus- is involved in interpretation of sensory input Output- amygdala Hypothalamus Autonomic nervous system (locus coeruleus) Theories of Emotion: Questions:  Do autonomic experience create emotion?  Or, Are autonomic responses due to emotion?  QUIZ:  Which theory regarding the initiation of emotion is most persuasive and why? Explain why the other theories are not persuasive.    Main Theories are: Biological:  William James  Walter Cannon  Cognitive:  Stanley Schacter  Richard Lazarus James-Lange Peripheral Theory Explained how physiological responses relate to emotional experiences. “Experience of emotion depends on Feedback from physiological responses outside the brain.”  Physical arousal  then emotion  You see a bear and you run- said you are afraid because you run  Activity of the peripheral nervous system is a cause of emotional experience.  Perception of the bear, causes physiological response and then the fear follows.  “once you strip away all physiological responses, nothing remains of the experience. Emotion, must therefore be the result of experiencing a particular set of physiological responses.”  Cannon-Bard Theory Central Theory          Pg. 445 Cannon-Bard Theory Central Theory Disagreed with James Cannon argued you feel fear at sight. (Sensory) We see a Bear- we feel fear- you feel fear at the sight of Bear even before you run. Emotional experience starts in central nervous system specifically in the Thalamus Thalamus- is the structure that relays information from most sense organs to cortex. Central Theory says “When thalamus receives sensory information about emotional events and situations, it sends signals to ANS and at some time to the cerebral Cortex when emotions become conscious.” Updated Version: Says really the “Amygdala seat of emotion”  Cannon said that the experience of emotion appears directly in the brain with or without feedback from peripheral responses (contradicts James)  “Emotion occurs through the activation of specific circuits in the central nervous system.” Schacter (early 1960s) Cognitive Interpretation of Body Responses   “The emotions we experience everyday are shaped partly by how we interpret the arousal we feel.” Response to James Theory- said physiology is too simplistic an explanation, it does not address all the shades of emotion.  He argued that emotions emerge from a combination of feedback from peripheral responses and the cognitive interpretation of the nature and cause of those responses.”  You notice the arousal then interpret the cause of the arousal. Physio and Cognitive interpretation – you do have arousal but there is a label the bodily reaction as a specific emotion. Attribution- is the process of identifying the cause of an event Physiological arousal might be attributed to several emotions depending on the situation Excitation Transfer: “A phenomenon in which physiological arousal from one experience carries over to affect emotion in an independent situation.” Example: “When people have been aroused by physical exercise become more angry when provoked, or experience more intense sexual feelings when in the company of an attractive person, than do people who are less physically active.”       Lazarus Cognitive Appraisal Theory       It is cognitive interpretation of events themselves that determine emotional experiences Example: a person’s interpretation of a grade on a test will be determined by the grade itself. How we think events will affect our personal well being A cognitive appraisal (evaluation) If the event is relevant to our wellbeing we experience an emotional reaction Positive or negative based on our appraisal depending whether we see the event as advancing our personal goals or obstructing them. Emotions Help and can cause problems- hate, anger, fear  Disrupts behavior and damages relationships  Physiological- bodily responses  Posture, tone, facial expressions, body language= emotional outward expressions  Sympathetic nervous system ANS= responses to emotion. Sympathetic= activates emotion, arousal, fight or flight  Parasympathetic- opposite. Slows down the reaction and conserves energy.  Plutchik Plutchik’s 8 primary emotions: Fear, surprise, sadness, disgust, anger, anticipation, joy, and trust/ acceptance  They fluctuate in intensity and can be mixed and yield to another emotion (hybrid emotion)  Moods are tied to circadian rhythms.  Brain and Emotion Positive emotion= left hemisphere. Sense of humor  Negative emotion= right hemisphere.  Some emotional processing= cerebral cortex  Amygdala= fear, strong emotion  Facial Expressions Expressing Emotions: Ekman “Psychologists believe that emotional expressions evolved to communicate our feelings to others which aids survival” People more sensitive to angry, scheming thinking, faces… Basic Facial expressions seem to be universal Cultural Differences in Emotion Asian cultures- group harmony is important  - Anger is not a public emotion  America and Western Europe= Anger is common  reflects values of independence + rights  justice
