Introduction to Motivation Instinct Theory Drive-Reduction Theory Arousal Theory Hierarchy of Motives

Slide 2

Motivation Motivation is a need or desire that energizes behavior and directs it towards a goal. Aron Ralston was motivated to cut his arm to free himself from a rock that pinned him down. Aron Ralston AP Photo/ Rocky Mountain News, Judy Walgren

Slide 3

Instincts & Evolutionary Psychology Instincts are complex behaviors that have fixed action patterns throughout species and unlearned (Tinbergen, 1951). Where the woman can build different kinds of houses the bird builds only one kind of nest. Ariel Skelley/ Masterfile Tony Brandenburg/ Bruce Coleman, Inc.

Slide 4

Drive-Reduction Theory When the instinct theory of motivation failed it was replaced by drive-reduction theory. Physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need (Hull, 1951).

Slide 5

Drive Reduction Food Drive Reduction Organism Physiological aim of drive reduction is homeostasis maintenance of steady internal state, e.g., maintenance of steady body temperature. Stomach Full Empty Stomach (Food Deprived)

Slide 6

Incentive Theory Where our needs (drives) push, incentives (positive or negative stimuli) pull us in reducing our drives. A food-deprived person who smells baking bread (incentive) feels strong hunger drive. Incentives can also be negative, we may behave in a certain way in order to avoid an unpleasant outcome You should see the connection between this theory and Behaviorist principles of learning (conditioning, Law of Effect, and the Premack Principle)

Slide 7

Cognitive Theory Motivation results from individuals attempting to maintain order or balance and an understanding of the world. Believes that individual behavior is influenced by the way people perceive themselves and their environment. People seek to maintain order and understanding. Students are motivated to engage in learning tasks to the extent that they expect to succeed and the degree to which they value the achievement of the task. 7

Slide 8

Optimum levels of Arousal Human motivation aims not to eliminate arousal but to seek optimum levels of arousal We each have our own sense of appropriate arousal and we act in ways to remain at a comfortable level. Yerkes-Dodson Law predicts that there is a relationship between the difficulty of a task, our level of arousal, and the eventual outcome For easy tasks=higher levels of arousal For difficult tasks= moderate levels work best

Slide 10

Hierarchy of Motives Abraham Maslow (1970) suggested some needs have priority over others. Physiological needs like breathing, thirst and hunger come before psychological needs like achievement, self-esteem and need for recognition. (1908-1970)

Slide 11

Hierarchy of Needs Physical Needs Psychological Needs

Slide 12

Hunger Physiology of hunger Parts of the hypothalamus Set Point theory Eating Disorders

Slide 13

Hunger When are we hungry? When do we eat? When there is no food in our stomach. When we are hungry. How do we know when our stomach is empty? Stomach growls. Also called hunger pangs.

Slide 14

The Physiology of Hunger Stomach contractions (pangs) send signals to the brain making us aware of our hunger.

Slide 15

Glucose: C 6 H 12 O 6 Glucose level in the blood is maintained. Insulin decreases glucose in blood making us feel hungry. Glucose Molecule

Slide 16

Glucose & Brain Levels of glucose in the blood are monitored by receptors (neurons) in the stomach, liver, intestines, they send signals to the hypothalamus in the brain. Rat Hypothalamus

Slide 17

Hypothalamic Centers Lateral hypothalamus (LH) brings on hunger (stimulation). Destroy it and the animal has no interest in eating. Reduction of blood glucose stimulates orexin in LH which leads to ravenous eating in rats.

Slide 18

Hypothalamic Centers Ventromedial hypothalamus (VMH) depresses hunger (stimulation). Destroy it and the animal eats excessively.

Slide 19

Hypothalamus & Hormones Hypothalamus monitors a number of hormones that are related to hunger. HormoneTissueResponse Orexin increaseHypothalamusIncreases hunger Ghrelin increaseStomachIncreases hunger Insulin increasePancreasIncreases hunger Leptin increaseFat cellsDecreases hunger PPY increaseDigestive tractDecreases hunger

Slide 20

Set-Point Theory Manipulating lateral and ventromedial hypothalamus alters the bodys weight thermostat. If weight is lost food intake increases and energy expenditure decreases. If weight is gained the opposite takes place.

Slide 21

The Psychology of Hunger Memory plays an important role in hunger. Due to difficulties with retention, amnesia patients eat frequently, if given food (Rozin et al., 1998). On the other hand, Alzheimers patients may forget to eat.

Slide 22

Eating Disorders Anorexia Nervosa: Characterized by a normal- weight person (usually adolescent women) losing weight continuously and yet feeling overweight. Reprinted by permission of The New England Journal of Medicine, 207, (Oct 5, 1932), 613-617. Lisa OConnor/ Zuma/ Corbis

Slide 23

Eating Disorders Bulimia Nervosa: A disorder characterized by episodes of overeating, usually of high-calorie foods, followed by vomiting, laxative use, fasting, or excessive exercise.

Slide 24

Obesity http://www.cyberdiet.com A disorder characterized by excessive overweight. Obesity increases risk and health issues like cardiovascular diseases, diabetes hypertension, arthritis, and back problems.

Summary

Slide 26

Motivation at Work The healthy life, said Sigmund Freud, is filled by love and work. -Motivation at work and school

Slide 27

Attitudes Towards Work 1.Job: Necessary way to make money. 2.Career: Opportunity to advance from one position to another. 3.Calling: fulfilling a socially useful activity. People have different attitudes towards work. Some take it as a:

Slide 28

Flow & Rewards Flow is experience between no work and a lot of work. Flow marks immersion into ones work. People who flow in their work (artists, dancers, composers etc.) are driven less by extrinsic rewards (money, praise, promotion) and more by intrinsic rewards.

Slide 29

Work and Satisfaction In industrialized countries work and satisfaction go hand-in-hand.

Slide 30

Industrial-Organizational (I/O) Psychology Applies psychological principles to workplace. 1.Personnel Psychology: Principles of selecting and evaluating workers. 2.Organizational Psychology: Studies how work environments and management styles influence worker motivation, satisfaction, and productivity.

Slide 31

Harnessing Strengths Identifying peoples strengths (analytical, disciplined, eager to learn etc.) and matching them to work is the first step toward workplace effectiveness.

Slide 32

Organizational Psychology: Motivating Achievement Achievement motivation is defined as desire for significant accomplishment. Skinner devised a daily discipline schedule which led him to become 20 th century most influential psychologist. Ken Heyman/ Woodfin Camp & Associates

Slide 33

Satisfaction & Engagement Harter et al., (2002) observed that employee engagement meant that the worker knows: 1.What is expected of him. 2.Feels the need to work. 3.Feels fulfilled at work. 4.Gets opportunities to do the best. 5.Thinks himself to be a part of something significant. 6.Has opportunities to learn and develop. Engaged workers are more productive than non-engaged at different stores of the same chain. Capital-Journal/ David Eulitt/ AP/ Wide World Photos

Slide 36

Introduction to Emotion 1.James Lange Theory 2.Cannon-Bard Theory 3.Schacter-Singer Theory (2 factor) 4.Autonomic Nervous System

Slide 37

Theories of Emotion Emotions are our bodys adaptive response. Emotions are a mix of 1) physiological activation, 2) expressive behaviors, and 3) conscious experience.

Slide 38

Controversy 1)Does physiological arousal precede or follow your emotional experience? 2)Does cognition (thinking) precede emotion (feeling)?

Slide 39

James-Lange Theory William James and Carl Lange proposed an idea that was diametrically opposed to the common- sense view. James-Lange theory proposes that physiological activity precedes the emotional experience. (We react to the changes in our body that we feel)

Slide 40

Cannon-Bard Theory Walter Cannon and Phillip Bard questioned James-Lange theory and proposed emotion- triggering stimulus and body's arousal take place simultaneously.

Slide 41

Two-Factor Theory Stanley Schachter and Jerome Singer proposed yet another theory which suggested that our physiology and our cognitions create emotions. Emotions have two factors physical arousal and cognitive label.

Slide 42

Embodied Emotion We know that emotions involve bodily response. Some of these response are easy to notice (butterflies in stomach when fear arises) but others are more difficult discern (neurons activated in the brain).

Slide 43

Emotions and Autonomic Nervous System During an emotional experience our autonomic nervous system mobilizes energy in the body and arouses us. 43

Slide 44

Arousal and Performance (remember Yerkes-Dodson??) Arousal in short spurts is adaptive. We perform better under moderate arousal, however optimal performance varies with task difficulty.

Slide 45

Physiological Similarities Physiological responses are pretty much similar across the emotions of fear, anger, love and boredom. Excitement and fear involve similar physiological arousal. This can be an issue when you study stress, which in our lives has physical consequences to psychological triggers. Your body only has one response to stress and it involves activating your sympathetic nervous system. This is not always healthy

Slide 46

Cognition and Emotion What is the connection between how we think (cognition) and how we feel (emotion)? Can we change our emotions by changing our thinking?

Slide 47

Cognition Can Define Emotion Arousal response to one event spills over into our response to the next event. Arousal from a soccer match can fuel anger, which can descend into rioting. AP Photo/ Nati Harnik Reuters/ Corbis

Slide 48

Two Routes to Emotion Zajonc and LeDoux (1984) emphasize some emotions are immediate without conscious appraisal. Lazarus, Schachter and Singer (1998) emphasize that appraisal also determines emotions.

Slide 49

Nonverbal Communication Most of us are good at deciphering emotions thorough non-verbal communication. In a crowd of faces a single angry face will pop out faster than a single happy face (Fox et al. 2000).

Slide 50

Gender, Emotion, and Nonverbal Behavior Women are much better at discerning nonverbal emotions then men. When shown sad, happy and scary film clips women expressed emotions more than men.

Slide 51

Culture and Emotional Expression When culturally diverse people were shown basic facial expressions, they did pretty well at recognizing them (Ekman & Matsumoto, 1989). Elkman & Matsumoto, Japanese and Caucasian Facial Expression of Emotion

Slide 52

Emotions are Adaptive Darwin speculated that our ancestors communicated with facial expression in the absence of language. Nonverbal facial expression led to their survival. Charles Darwin (1809-1882)

Slide 53

Analyzing Emotion Analysis of emotions is carried out on different levels.

Slide 54

Experienced Emotion 1.Fear 2.Anger 3.Adaptation-level phenomenon 4.Relative deprivation

Slide 55

Experienced Emotion Izard (1977) has isolated 10 emotions. And most of them are present in infancy, excluding contempt, shame and guilt. Nancy Brown/ The Image Bank Tom McCarthy/ Rainbow

Slide 56

Dimensions of Emotion People generally divide emotions into two dimensions

Slide 57

Fear Fear can torment us, rob us of sleep and preoccupy our thinking. But fear can be adaptive it makes us run away from danger, brings us closer as groups, protects us from injury and harm.

Slide 58

Learning Fear We learn fear in two ways through conditioning and/or through observation. Watson Bandura

Slide 59

The Biology of Fear Some fears are easier to learn than others. The amygdala in the brain associates emotions like fear with certain situations and its proximity to the hippocampus allows for the easy encoding of these memories.

Slide 60

Causes of Anger 1.People generally get angry with friends and loved ones about misdeeds, especially if they are willful, unjustified, and avoidable. 2.People also get angry about foul odors, high temperatures, traffic jams, aches and pains.

Slide 61

Catharsis Hypothesis Venting anger through action or fantasy achieves emotional release or catharsis. Some believe that we are drawn to displays of violence (football, etc) because it is cathartic and allows us an outlet for aggression. Expressing anger breeds more anger, and through reinforcement, is habit forming.

Slide 62

Emotional Ups and Downs Our positive moods rise to a maximum within 6-7 hours after waking up. Negative moods stay more or less the same over the day.

Slide 63

Feel-Good, Do-Good phenomenon When we feel happy we are more willing to help others. This is a good example of the spill over effect

Slide 64

Happiness & Satisfaction Subjective well-being (happiness + satisfaction) measured in 82 countries show Puerto Rico and Mexico (poorer countries) at the top of the list.

Slide 65

Happiness & Prior Experience Adaptation-Level Phenomenon: Like sensory adaptation to brightness, volume, and touch, people adapt to new situations until that situation becomes the norm. Then people need a new experience. This constantly raises the level for what is considered new and exciting In baseball, the Cardinals are used to being a successful team, and we are used to rooting for a winner. What would happen if they started having really bad seasons?

Slide 66

Slide 67

Happiness & Others Attainments Happiness is not relative to our past but also to our comparisons with others. Relative Deprivation is the perception that one is worse off relative to those with whom one compares oneself with. They realize that they have less of what they believe themselves to be entitled than those around them. Can lead to social movements, deviance, rioting, civil wars, etc
