Instinct theory (now replaced by evolutionary perspective) - focuses on genetically predisposed behaviors. Drive-reduction theory - focuses on how our inner pushes & external pulls interact. Arousal theory - focuses on nding the right level of stimulation. Maslow"s hierarchy of needs - describes how some of our needs take priority over others. Early in 20th century as the in uence of darwin"s evolutionary theory grew, it became fashionable to classify all sorts of behaviors as instincts. It was like explaining a bright child"s low grades by labeling the child an underachiever . to name a behavior is not to explain it. To quality as an instinct, a complex behavior must have a xed pattern throughout a species & be unlearned.
