Document Summary

Give examples of questions that psychologists studying motivation might ask. Describe the evidence supporting, and the problems associated with, the instinct theory of motivation. Fixed-action patterns: automatic, unlearned responses, genetically coded response to a specific releaser stimulus . Modern versions are interested in ultimate (evolutionary) causes of human behavior. Instinct doctrine suggests that behavior is motivated by automatic, involuntary and unlearned responses. Motivation can be influenced by inherited tendencies but that does not mean that all motivated behavior is genetically determined: define homeostasis, drive reduction theory, need, and drive. Define and give examples of primary and secondary drives. Describe the kinds of behavior that drive reduction theory can and cannot explain.

Psychological state arising from an imbalance in homeostasis and prompts action to fulfill a need.
