Document Summary
Influences that account for the initiation, direction, intensity and persistence of behavior: motive: a reason or purpose of the behavior, four general sources, biological factors. Food, water, sex temperature regulation : emotional factors. Panic, fear, anger, love, hatred : cognitive factor. Perception, beliefs, expectations : social factors. Theories of motivation: instinct theory (internal processes) Instincts are automatic, involuntary behaviour patterns consistently triggered or released by certain stimuli. Also called fixed-action patterns because they are unlearned, genetically codes responses. Problem: doesn"t explain the behavior : evolutionary perspective (newer instinct theory) Certain behaviours have evolved to assure our survival. Ex: fear of snakes, because they are dangerous : drive-reduction theory (internal processes) Based also on biological factors, but based on the concept of homeostasis. Homeostasis: body in a calm state normal, balanced . Primary drives biological needs: food, water, oxygen . Secondary drives learned drives : money : arousal theory (internal processes)
