PSY B110 Chapter Notes - Chapter 6: Evolutionary Psychology, Ethology, Homeostasis
Document Summary
Motivation - the forces that activate and direct behavior. Emotion - a complex internal state that involves physiological, cognitive, and behavioral components. Evolutionary psychology - branch of psychology that seeks to explain behavior in terms of its function. Instincts - behaviors that do not require previous experience or learning. Unlearned behaviors - behaviors that are apparent from a very early age onwards and require very little experience to emerge. Ethology - field that seeks to study the behavior of animals in their natural habitat. Modal action patterns - behaviors that occur in the same fashion, time and time again, and are present in nearly every individual. Drives - a central concept in motivation, internal forces that provide us with the energy and intensity to regain homeostasis. Drive-reduction - occurs after we begin to reduce a need, when we begin to feel better.
