Motivation Module 11

September 11, 2001 Four passenger planes hijacked by terrorists. Deliberately flew 3 of aircraft into US buildings. Killed 2,998 people. What were their motives?

Motivation Why do we do what we do? From Latin word movere – move A need or desire that energizes and directs behavior toward a goal Biological, cognitive, clinical explanations Why do we do what we do?

Historic Explanations: Instinct(s) A complex, inherited, unlearned behavior that is rigidly patterned throughout a species William James listed 37 instincts. Includes mental ones: Jealously, curiosity, and cleanliness Original psychological explanation of motivation. Problems: Difficulty using instincts to both label and explain behaviors Theorists came up with more than 10,000 + instincts.

Historic Explanations: Drives States of tension that result from internal imbalance. Prompt an organism to restore the balance, typically reducing the drive Ex: skipping breakfast Come 10:00am you are starving Creates a physiological need for food, leads to hunger, a psychological drive.

Drive-Reduction Theory The idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need Eating and drinking are examples of drive-reducing behaviors.

Biological Explanations: Arousal Theories What is the basic idea in arousal theories of motivation? Is homeostasis the same as drive reduction? Module 11: Motivation

Biological Explanations: Arousal Theories Levels of alertness and responsiveness Let’s look at 3 friends the night before the SAT: A: “You know, I don’t really care about the test. I’m going to a trade school, and I’m only taking the test b/c my parents want me to. Can I have some of your fries?” B: “I want to do well, but if I screw up on this test, it’s not going to permanently ruin my life. I’ll give it my best shot. Where’s the ketchup?” C: “It’s all on the line tomorrow. If I don’t get a good score, it will change my life forever. I’m so nervous, I can’t eat.” Which one are you? Who will do better on the test?

Yerkes-Dodson Law The theory that a degree of psychological arousal helps performance, but only up to a certain point Optimum level of arousal depends on the difficulty of the task. Each person has an optimum level of stimulation they like to maintain. Which friend would perform best according to this law? Friend B

Yerkes-Dodson Law Basically arousal will increase performance up to a point. Further arousal impairs performance. Optimal arousal changes with difficulty of a task. Simple task – higher arousal higher performance. Difficult task – lower arousal works best How does this relate to stress?

Biological Explanations: Homeostasis A tendency to maintain a balanced or constant internal state Ex: Movie “Bio-dome”. The regulation of any aspect of body chemistry, such as blood glucose, around a particular level Any change in levels, up or down, results in being motivated to bring the level back to normal. What is your homeostasis with body temp?

Cognitive Explanations: Intrinsic and Extrinsic Motivation Why is intrinsic motivation more beneficial than extrinsic movtivation? Module 11: Motivation

Extrinsic & Intrinsic Motivation Motivation A desire to perform a behavior because of promised rewards or threats of punishment Examples: Home, work, school Do you study b/c you want an “A” or because you want to learn the material? A desire to perform a behavior for its own sake and to be effective Do you participate in class for bonus cards or b/c you just want to?

Which is better? Intrinsic motivation often results in higher achievement. Behavior maintained by extrinsic motivation alone may not be effectively sustained once the rewards are removed. Evidence says removal of an extrinsic motivator may result in behavior levels even lower than before the rewards were given. Do you have any experiences that support these statements? Is everything about rewards and punishment? Do we have free will????

Clinical Explanations: Hierarchy of Needs Abraham Maslow (1908-1970) Humanistic psychologist who developed the hierarchy of needs

Hierarchy of Needs Maslow’s pyramid of human needs begins at the base with physiological needs, and then proceeds through safety needs to psychological needs. Higher-level needs won’t become active until lower-level needs have been satisfied. Self-Actualization: According to Maslow, the need to live up to one’s fullest and unique potential

Clinical Explanations: Achievement Henry Murray (1893-1988) Neo-Freudian who first established the concept of achievement motivation Includes a desire for: Significant accomplishment The mastery of things, people, or ideas Attaining a high standard

Clinical Explanations: Motivating Ourselves Motivating Others Cultivate intrinsic motivation Attend to individual motives Set specific, challenging goals Choose an appropriate leadership style Task leadership Social leadership Developing Self Motivation: Associate your high achievement with positive emotions Connect your achievement with your efforts Raise your expectations

Motivating Others (cont.) Task and Social Leadership Leadership Goal-oriented leadership that sets standards, organizes work, and focuses attention Group-oriented leadership that builds teamwork, mediates conflict, and offers support

Theories on Motivation: summary Biological: Arousal: Yerkes-Dodson Homeostasis Cognitive: Intrinsic and Extrinsic Motivation Chemical: Maslow’s Hierarchy Achievement Motivating ourselves and others

A Closer Look the Physiology of Hunger Glucose: Form of sugar which circulates through the body One feels hunger when the levels become low. Insulin Hormone which allows the body to use glucose for energy or fat production Insulin levels up glucose levels down. Leptin Protein produced by bloated fat cells Send a message to “stop eating” Orexin Hunger-triggering hormone Produced by the hypothalamus As glucose levels drop, orexin levels increase and person feels hungry

Hypothalamus: set point theory Weight thermostat. Maintains a set point. Damage to this can lead to severe weight gain or loss. 1.) We have a Basal Metabolic Rate (resting rate at which we burn calories for energy). 2.) We have a specific number of fat cells (which can expand in size and increase in #). 3.) We have hormones that work together to keep our weight where it is designed to be.

Basal Metabolic Rate (BMR) The body’s resting rate of energy expenditure Set Point The point at which an individual’s “weight thermostat” is supposedly set. When the body falls below this weight, increased hunger and a lower basal metabolic rate (BMR) may act to restore the lost weight.

Set Point: Might be a good idea to get this!

Environment and Hunger: External Incentives Include the sight, sound, and smell of food Cultural Influences on Eating Cultural views on obesity can vary Culture influences the foods we like and dislike.

Eating Disorders: Why do people develop eating disorders? Module 11: Motivation

Anorexia Nervosa An eating disorder in which normal weight people suffer delusions of being overweight Usually in adolescent females May put themselves on self-starvation regimens May become dangerously underweight

Bulimia Nervosa An eating disorder characterized by episodes of overeating Usually overeat high calorie foods Overeating is followed by vomiting, using laxatives, fasting, or excessive exercise
