1. Motivation and Emotionstolen off www.appsychology.commajorly altered by Mr. C.

3. Motivation • Instinct Theory: we are motivated by our inborn automated behaviors. • But instincts only explain why we do a small fraction of our behaviors.

4. Drive Reduction Theory • Our behavior is motivated by BIOLOGICAL NEEDS. • Wants to maintain homeostasis. • When we are not, we have a need that creates a drive. • Primary versus Secondary drives

5. Arousal Theory We are motivated to seek an optimum level of arousal.

6. Yerkes-Dodson Law The Yerkes-Dodson Law says we perform best under the optimal amount of arousal. (Like Goldilocks) Not too much, not too little. video

7. Maslow’s Hierarchy of Needs • Abraham Maslow said we are motivated by needs, and all needs are not created equal. • We are driven to satisfy the lower level needs first.

8. Motivation of HUNGER

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

10. Hypothalamus Lateral Hypothalamus Ventromedial Hypothalamus When stimulated you feel full. When lesioned you will never feel full again. • When stimulated it makes you hungry. • When lesioned (destroyed) you will never be hungry again. I’m late for lunch. I’m hungry. The lateral hypothalamus makes you hungry.

11. Unlearned biological motives necessary for survival are termed • primary motives • secondary motives c. drives d. stimulus motives

12. Jose complains that he can play his tuba beautifully at home but not on stage at the talent show. His problem can be explained by a. Yerkes-Dodson Law b. effects of homeostasis c. habituation d. biorhythms

13. The most critical physiological factor controlling hunger is the • level of blood sugar • stomach contractions c. taste of food d. presence of fatigue

14. The maintenance of steady states of temperature and blood pressure are examples of • thermostasis • homeostasis c. intrinsic motivation d. biological rhythm

15. Electrically stimulating the lateral hypothalamus will cause a rat to • start eating • stop eating c. start drinking d. stop drinking

16. If the lateral hypothalamus is destroyed, a rat will a. drink more water than biologically needed b. refuse to drink until forced to do so. c. eat until it becomes obese d. refuse to eat until force fed.

17. 16. The employees at a factory were excellent workers until a week before Christmas when a rumor spread that economic conditions would force the plant to close in four days. The quality and quantity of work took a down turn as the workers spent time discussing among themselves the plausibility of the rumor and what they would do if it were true. Maslow would say that these workers were motivated by • meta-needs • intrinsic motivation c. esteem and self-esteem d. safety and security

18. Set Point Theory The hypothalamus acts like a thermostat. Wants to maintain a stable weight (homeostasis). Activate the lateral when you diet and activate the ventromedial when you start to gain weight. Ghrelin video

19. Body Chemistry • Glucose • The hormone insulin converts glucose to fat. • When glucose levels drop- hunger increases.

20. Psychological Aspects of Hunger • Internals versus Externals • The Garcia Effect

21. Culture and Hunger

22. Dog Mice Wine Fried Frog Legs Criadillas- bull testicles.

23. Eating Disorders Bulimia Nervosa • Characterized by binging (eating large amounts of food) and purging (getting rid of the food).

24. Anorexia Nervosa • Starve themselves to below 85% of their normal body weight. • See themselves as fat. • Vast majority are women.

25. Obesity • Severely overweight to the point where it causes health issues. • Mostly eating habits but some people are predisposed towards obesity. Click on the pictures to see some case studies on obesity.

26. Sexual Motivation • Sex is natural. • Without sex, none of us would be here. • How do scientists (or you) find out about sex? YOU ASK!!!!!!

27. Kinsey’s Studies • Confidential interviews with 18,000 people (in early 1950’s). • Sexual Behavior in the Human Male and Sexual Behavior in the Human Female • Scale of sexuality….0 to 6 where 0 is exclusively heterosexual and 6 homosexual and 7 is asexual. • Problem: sample was not randomized!! Self-selected sample. Click on Kinsey to see the movie trailer.

28. Masters and Johnson Study • In the 1960’s William Masters and Virginia Johnson set out to explore the physiology of sex. • 382 females and 312 males. After their research was done they ran an institute that claimed to turn gay people straight.

29. Mapped out the Sexual Response Cycle • Initial Excitement • Plateau Phase • Orgasm • Resolution Phase (with refractory period).

30. Psychological Factors in Sexual Motivation • Only some people are externals when it comes to hunger- but we are all externals when it comes to sex. • Heiman 4 tape study. • People can find sexually explicit images either pleasing or disturbing- but they are none the less biologically arousing.

31. Pheromones • A pheromone is a chemical secreted by one creature to affect behavior of another (usually sex related). • Pheromones might explain why women’s menstrual cycles get in synch when they live together.

32. We have discussed the energizing of sexual motivation but have yet to discuss its direction: Sexual Orientation An enduring sexual attraction toward members of either one's own gender or the other gender.

33. How is Sexual Orientation Determined • There has been NO evidence that sexuality is socially determined. • Kids raised by gay parents are no more likely to be gay than if they were raised by hetero parents. • Thus, it is likely biologically determined.

34. The Brain Simon LeVay discovered that there is a cluster of cells in the hypothalamus that is larger in heterosexual men than in heterosexual women or homosexual men. Is this cause or effect??

35. Prenatal Environment Current research seems to point to the hormonal levels in the prenatal environment. We have created homosexual male fruit flies and lesbian sheep!!! Monozygotic twins can differ in sexual orientation.

36. Genetic cause of homosexuality • Some studies show a genetic similarity in the X chromosome for gay males. • Whether it’s genetic or hormonal, either way it’s not environment.

37. Achievement MotivationWhat motivates us to work?(School, job, sports, video games, relationships etc..) Intrinsic Motivators Extrinsic Motivators Reward that we get for accomplishments from outside ourselves (grades or money or etc..) Work great in the short run. • Rewards we get internally, such as enjoyment or satisfaction.

38. Achievement motivation Where would one stand to practice if they had high achievement motivation? Those with high achievement motivation will choose tasks that are moderately difficult. Not too hard because they want to achieve. Not too easy because they want to feel good about themselves.

39. Overjustification effect Studies show that if you externally reward someone (excessively) for something they love doing, they will lose their intrinsic desire for doing it. • Alex Rodriguez earns 27.5 million dollars per year. Does he love the game??

40. Management TheoryManagement/Teaching styles relate closely to Intrinsic/Extrinsic Motivators. Theory X Theory Y Managers believe that employees are internally motivated to do good work and policies should encourage this internal motive. Interested in Maslow’s higher needs. Managers believes that employees will work only if rewarded with benefits or threatened with punishment. Think employees are Extrinsically Motivated. Only interested in Maslow’s lower needs.

41. Intrinsic motivation occurs when a. obligations or approval are factors b. there is no obvious external reward for one’s behavior c. there are obvious external factors controlling behavior d. extrinsic motivation is also high

42. When Motives Conflict • Approach-approach conflict – when we have 2 desirable things to choose from. Both Beyonce and Tyra Banks want to date you.

43. Approach –avoidance conflict Both options have their benefits and drawbacks. Example, telling your wife that her hair looks bad. The good is she’ll fix it. The bad is she might be mad at you for a few hours.

44. Avoidance-avoidance conflict • You must choose between 2 equally unattractive options.

45. Four theories of emotion

46. James-Lange Theory of Emotion • Willam James and Carl Lange came up with the James-Lange Theory of Emotion. • Based on our autonomic nervous system • The body changes and our mind interprets those changes as emotion. • “I’m afraid because I run”

47. Male participants were asked to meet an interviewer in the middle of one of two bridges. One was a safe-looking bridge and one looked more dangerous. An attractive female researcher interviewed the male passers-by in the middle of the two bridges. She gave them her telephone number in case they wanted to ask about the results. Men on the less safe-looking bridge were more aroused by the height of the bridge, and were likely to confuse their feelings for being 'lovestruck'. They were then more likely to call her back, looking for a date. • Support for James Lange????

48. Giving the Finger, the Psychology and History Thereof By William Weir on February 13, 2009 • For the study, 54 right-handed subjects read a story about a person whose behavior could be interpreted as either assertive or hostile. One group extended their forefinger while reading, another group extended their middle finger. The latter group tended to assert that person in the essay was hostile, rather than assertive. • Support for the James Lange theory??

49. Facial feedback hypothesis

50. The Effects of Facial Expression If facial expressions are manipulated, like furrowing brows, people feel sad while looking at sad pictures.
