Theories of Motivation

Drive-Reduction TheoryHumans sometimes engage in behaviors that

increase rather than reduce drives Arousal Theory

Motivated to be at optimal level of arousal

Page 5: Motivation and Emotion. Motivation internal processes that activate, guide, and maintain our behavior.

Yerkes-Dodson Law There is an optimal level of arousal for the

best performance of any task. The more complex the task, the lower the level of

arousal that can be tolerated before performance deteriorates.

Identify the motive… Have I got a terrible headache. It’s really

splitting. It gets lonely in my apartment on the

weekends. My roommate goes to visit her parents and most of my neighbors are away too.

I feel really bored by this course. It’s a lot like the one I took last year. I was hoping it would be more challenging.

Identify the motive…

He really makes me furious. I’m tired of his put-downs! Who does he think he is anyway?

Human Needs & Motivation

Hunger and Thirststimulated by internal and external cues

Hypothalamus (lateral and ventromedial) Blood levels

Glucose, fats, carbohydrates, insulin, leptin

Cells in stomach and small intestine

Page 13: Motivation and Emotion. Motivation internal processes that activate, guide, and maintain our behavior.

Insulin: secreted by pancreas; controls blood glucose

Leptin: protein secreted by fat cells; when abundant, causes brain to increase metabolism and

decrease hunger Orexin: hunger-triggering

hormone secreted by hypothalamus Ghrelin: hormone secreted by empty

stomach; sends “I’m hungry” signals to brain

PYY: digestive tract hormone; sends “I’m not hungry” signals to brain
