MOTIVATION EMOTION HUNGRY What motivates you to eat

MOTIVATION & EMOTION

HUNGRY? What motivates you to eat? Is it physiological (physical) factors or psychological (mental) factors? Could it be a combination of both? Did the pictures in the previous slides make you hungry? If they did, then you were psychologically motivated.

HUNGRY? How could Need for Achievement have impacted the lives of these people?

Motivation is an internal state that activates behavior and directs it toward a goal

FOUR THEORIES OF MOTIVATION Instincts Drive-Reduction Theory Incentive theory Cognitive theory

INSTINCT THEORY We are motivated by a variety of instincts (innate tendencies that determine behavior) • early 1900’s. • Do not explain behavior; simply label it

Drive-Reduction Theory We have needs that produce drives (an internal condition that orients an individual toward a specific goal) Biological needs drive us to action. We are motivated/driven to reduce our needs. Hunger drives us to eat • Fatigue drives us to rest • Focuses on physiological needs

It’s more than just a DRIVE…… Infant attachment to their mothers Drive-Reduction Theory: Hunger & Thirst Harry Harlow proved that a loving, comforting touch (contact comfort) motivated monkeys more than hunger or thirst. Incentives (things we learn to value) are a key to motivation

INCENTIVE THEORY Incentives are an external stimulus, reinforcer, or reward that motivates behavior Drives and Incentives work together Hunger may cause you to walk to the café (drive). The incentive is the cheese steak.

COGNITIVE THEORY Actions are the result of Intrinsic & extrinsic motivations Intrinsic: comes from within. We engage in behaviors because they are personally rewarding Extrinsic: comes from outside. We engage in behaviors that reduce biological needs or help us obtain incentives or external rewards

INTRINSIC vs. EXTRINSIC A desire to perform a behavior for its own sake and to be effective. A desire to perform a behavior due to promised rewards or threats of punishment. Why are you in AP Psych? • Interesting • Parents. • Curiosity • Need the credit. • Competent • Save money in college.

Biological Needs - physiological requirements necessary for survival Social Needs – psychological needs acquired through learning and experience Studies showed that Obese people eat because of external (social) cues more than normal weight people. What influences our eating habits?

BIOLOGICAL/PHYSIOLOGICAL HUNGER FACTORS • Our body and brain send cues that cause us to eat. • The stomach, liver, and intestines send hunger cues • The hypothalamus in the brain receives the cues from your organs and signals you to eat. GENETIC HUNGER FACTORS Inherited instructions found in our genes. • Determine metabolic rate • Everyone has a set point (a certain level of body fat that our bodies strive to maintain constant throughout our lives) SOCIAL/PSYCHOLOGICAL HUNGER FACTORS Things you learn about eating • Ex. Eating while watching television • Ex. Peer pressure to stay a certain weight

Biological Basis of Hunger does NOT come from our stomach. It comes from our… Brain What part of the brain? The Hypothalamus

Physiology of Hunger Washburn’s studies showed hunger was partially related to the stomach. But those with their stomachs removed still feel hunger.

Body Chemistry Glucose The hormone insulin converts glucose to fat. When glucose levels drophunger increases.

The Brain In the 1960’s it was discovered that hunger comes from………. . The Hypothalamus

Lateral Hypothalamus Ventromedial Hypothalamus When stimulated it makes you hungry. When lesioned (destroyed) you will never be hungry again. When stimulated you feel full. When lesioned you will never feel full again.

The Psychology of Hunger What psychological and cultural factors influence hunger? Externals: people whose eating is triggered more by the presence of food than internal factors.

Douglas Mc. Gregor, Theories of X and Y THEORY

Theory X Assumes that works are basically lazy, error-prone, and extrinsically motivated by money. • Must never be trusted and always be watched. • To work more, they must be given money.

Theory X assumes people dislike work and do whatever they can to avoid it. This leads to the following: Because people hate work, they have to be forced, threatened or bribed before they will work hard enough. People like to be ordered about, they seek security in authority and go out of their way to avoid taking on responsibility. Money is the main motivating force. Issues to do with personal security come second. The only creativity most people display is when it comes to avoiding work or finding ways of getting around management edicts.

Theory Y Assumes that, given challenge and freedom, workers are motivated to achieve self-esteem and to demonstrate their competence and creativity.

two-factor theory, proposed by Frederick Herzberg He also surmised that it is the work itself and what people get out of it, rather than factors such as pay and physical working conditions, that determines job satisfaction.

Taste Preferences Food taste better and we chew less when we are hungry (beginning of a meal). Food tastes worse and we chew more when we are not hungry (at the end of the meal). Its weird, the better the food tastes, the less time we leave it in our mouths.

Sex & Motivation Is the desire to have sex biologically motivated, socially motivated, or both? Sex glands secrete hormones that control sexual interest (Biological) status, peer pressure, money (Social)

GENDER INFLUENCE ON SEXUAL MOTIVATION MALE FEMALE More interested in sex; initiate and think about sex more often Less interested in sex Want sex with more partners Not as interested in sex with many partners Desire sex without emotional commitment Desire sex with emotional commitment Focus on youth and physical attractiveness when choosing a sex partner Focus on social and economic status when choosing a sex partner Feel more jealous when partner is physically unfaithful is emotionally unfaithful

Sex and Motivation: Why do we have sex? Testosterone = sexual motivation Puberty = increased testosterone and estrogen Any correlation between teen sex and this maturation process? 29

The Journey of Sexual Arousal: Bet You Didn’t Know This One! When something gets your “sexual attention” your Hypothalamus sends a signal to the pituitary gland. The Pituitary gland then secretes two hormones (luteinizing and follicle stimulating) These hormones travel to your gonads (yes ladies you have gonads) – testes and ovaries Then your gonads provide you with the sensation of arousal. 30

Sex and Society: Sex has always been a taboo topic Companies spend millions of dollars a year on advertising that includes sexual images We have even imposed societal “norms” for sex: 1. NO incest 2. NO Premarital sex 3. Masturbation? 4. Homosexuality? Freud said that psychological disorders stem from the repression of sexual feelings. 31

Sex in the Media: 32

Homosexuality: Case Study 33

Reproduction: Much research has been done on the difference between genders on choosing a partner for reproduction: Females – Optimize reproductive success by being very selective in their mating They are more interested in mating with an individual that can provide adequate resources for their child. Males – Optimize reproductive success by mating with many females They seek young, healthy, and fertile mates 34

The Sexual Response Cycle: Masters and Johnson were two psychologists that researched the physiological changes that occur during sex. 1. The excitement stage 2. The plateau – increased breathing, muscle tension 3. Orgasm – males/ejaculation, females/muscle contraction 4. Resolution / Males have a refractory period in which achieving an erection is difficult 35

Need for Achievement = Social Motive Desire to set challenging goals and persist in trying to reach those goals What role does it play in the life of a high school student? Fear of Failure = Social motivate How can fear of failure impact your motivation?

Maslow’s Hierarchy of Needs Which needs to we satisfy first?

Hierarchy of Needs Important to remember, that Maslow’s definition of a Self actualized person: Has no mental illness Satisfied in basic needs Fully exploited talents Motivated by values http: //www. youtube. com/watch? v=cf. R 7 qxtg. Cg. Y

EMOTIONS Emotion is a set of complex reactions to stimuli involving subjective feelings, physiological arousal, and observable behavior.

Motivation & Emotion Motivation is the source of our behavior. Emotion is the feelings associated with our behavior. Emotions can function as motivation • i. e. Hit someone because you are angry • i. e. do it because it makes you happy

Four Components of Emotion 1. Interpret, appraise some stimulus (ex. Shark = serious threat) 2. Experience a feeling (fear, terror) 3. Physiological response (heart rate or breathing change) 4. Show observable behaviors (cry, panic, freeze)

There is a large debate on the order that the four basic components occur in. Therefore, we have different theories on Emotion. 1. Physiological Theories 1. Cognitive Theories

Physiological Theories of Emotion Main Belief – Emotions derive from physical changes in the body Physiological changes MAY NOT CAUSE emotions but they certainly increase their intensity. i. e. fear heightened when heart races (panic attack)

Cognitive Theories of Emotion Main Belief – Emotions result from mental processes and physiological changes working together

Universal Facial Expressions Paul Ekman – some facial expressions are universal & few of us (10 – 20%) could hide true emotions How can this information help us in life? Anger Fear Sadness Surprise Happiness Disgust Contempt
