Day 1 • Quiz • When done complete hope survey • Subscale Agency: add 2, 9, 10, and 12 • Subscale Pathway: add 1, 4, 6, and 8 • Total: add 1, 2, 4, 6, 8, 9, 10, 12 • Complete Exploration Inventory • Add up 1 – 18 • Reminder: Cognitive paper due Friday
Unit Overview • Motivational Concepts • Hunger • Sexual Motivation • The Need to Belong
Introduction • Why do you think people go to college? • Motivation
Instinct Theory of Motivation • Inspired by what perspective? • Instinct • Flaws of the instinct theory of motivation • Instinct theory does fail to explain human motives but research shows that genes do predispose our typical behavior (think evolutionary psychology and sex appeal)
Pushed by our ‘need’ to reduce drives • Drive-reduction theory Homeostasis
Pulled by Incentives • Incentive • Positive (lure us) and negative (repel us) • Example for food? • Need + incentive = strong drive • Hunger + smell of good food makes you very hungry
Optimum Arousal • Flaw of drive reduction theory • Optimum level of arousal
When your basic needs are met you can focus on other motives – if your basic needs are not met your strong drive to eat will take over and you will not be able to focus on other motives such as making and reaching goals • Whose theory does this describe?
Ancel Keys Research • Ancel Keys – 36 male participants cutting food portions in half for six months. Results?
The Physiology of Hunger • Washburn study: • Results: • Stomachs removed in rats – did they still eat?
Body Chemistry and the Brain • Glucose • What hormone reduces blood glucose? • Which brain part is in charge of hunger?
The hypothalamus and Hunger • Lateral hypothalamus • Stimulate: • Remove: • When blood sugar levels drop the lateral hypothalamus produces what hunger-triggering hormone? • Vetromedial hypothalamus • Stimulate: • Destroy it?
The Physiology of Hunger • Appetite hormones • Appetite suppressants: • Set point • Basal metabolic rate
The Psychology of Hunger • Hunger and amnesia • Taste preferences • When depressed we crave what? • I do not like sushi, how could I fix this? • Cultural differences: • we don’t eat dog, horse, rat
The Psychology of Hunger • Adaptive/evolutionary: • Neophobia • Conditioned: taste aversion • Pregnancy related nausea
Ecology of eating • Social facilitation: • Unit bias:
The Psychology of HungerEating Disorders • Eating disorders • Anorexia nervosa • Bulimia nervosa • Binge-eating disorder
Obesity and Weight Control • Historical explanations for obesity • Obesity • Obesity and life expectancy
The Social Effects of Obesity • Stereotypes: • Study results? • Weight discrimination • Psychological effects of obesity
Obesity and Weight ControlThe Physiology of Obesity • Fat Cells
Obesity and Weight ControlThe Physiology of Obesity • Set point and metabolism
The Physiology of Obesity • The genetic factor • The food and activity factor
Obesity and Weight ControlLosing Weight • Realistic and moderate goals • Success stories
A Twinkie Tax Is fighting fat a social responsibility? • “The nation’s obesity epidemic may soon overtake tobacco as the leading cause of preventable death, the U.S. Surgeon General has called for changes in policies – from schools to the fast-food industries- to combat the problem. “ • First: What can be done (in schools and community) • Second: Should it be done?
Sexual Motivation • How is it unlike hunger motivation? • How is it similar to hunger motivation? • Sexual motivation
The Physiology of SexThe Sexual Response Cycle • Sexual response cycle • Excitement phase • Plateau phase • Orgasm • Resolution phase
The Physiology of SexHormones and Sexual Behavior • Effects of hormones • Estrogen • Peak during ovulation – meaning what?
The Physiology of SexHormones and Sexual Behavior • Testosterone • Women: • Fluctuations of testosterone in men:
External stimuli Men and women report the same arousal in response to erotic material
External stimuli – Is pornographic material harmful? • Depictions of women being sexually coerced (and enjoying it) 2. Viewing images of sexually attractive women and men 3. After males view TV or magazine depictions of sexually attractive women 4. Viewing x-rated sex films
The Psychology of Sex - Imagined stimuli Brain can influence sexual arousal • Dreams • Sexual fantasies • Differences in fantasies? • Does fantasizing about sex indicate a sexual problem or dissatisfaction?
Adolescent Sexuality • Cultural differences • Environmental factors
Adolescent SexualityTeen Pregnancy • Ignorance • Minimal communication about birth control • Guilt related to sexual activity • Alcohol use • Mass media norms of unprotected promiscuity
Adolescent SexualitySexually Transmitted Infections • Statistics of STIs • Teen abstinence (engagement – school, religion, families, prosocial projects) • High intelligence • Religious engagement • Father presence • Participation in service learning programs
Sexual Orientation • Sexual orientation • Sexual orientation statistics
Sexual Orientation • Homosexuality not an indicator of mental health – but increased risk for suicidal thoughts and attempts. Why? • Erotic plasticity
Origins of Sexual Orientation • No found environmental causes • Differences in populations • Origins of sexual orientation studies • Fraternal birth order effect - unclear why • How do we know it is biological? • Same-sex attraction in animals
Origins of Sexual Orientation • The brain and sexual orientation • Gay men and straight women have brain hemispheres of similar size • Hypothalamic differences (involved in neural pathway engaged in sexual behavior) • Responses to hormone-derived sexual scents
Sexual OrientationOrigins of Sexual Orientation • Genes and sexual orientation • Prenatal Hormones
Sexual Orientation • Genes, parts of the brain, brain functions, prenatal hormones, birth order effect: many studies about homosexual orientation are correlation • What does this mean? • Not a (proved) causation
The Need to Belong • The pain of ostracism • Silent treatment, cyber-ostracism • negative consequences
The Need to Belong • Wanting to belong • Sustaining relationships
The Need to Belong • Aiding survival – how?
Motivation = a need or desire that energizes and directs behavior.
Instinct = a complex behavior that is rigidly patterned throughout a species and is unlearned.
