Document Summary
Clark leonard hall (behaviorist- all mechanistic; laws & mechanisms predict behavior) Explained learning and motivation by scientific laws of behavior. Hull(cid:859)s (cid:373)odel of (cid:271)ehavior is mechanistic and based on homeostatic drive reduction. Habits (stimulus-response associations) become stronger as a function of how often they are followed by satisfying events. The reduction of a drive is satisfying: the more satisfied you are, the more likely you are to seek the stimulus (i. e. eating sugar foods) We are going to learn satisfaction is irrelevant to change in behavior. Hull s model: ser= shr x d ser= strength of behavior shr= strength of learned response. Animals deprived for 3 hrs vs 22 hrs. 22 hr deprived animals had much more drive to get food i. e. if you come to each and find and eat strawberries, if you come back later you will look for them again when you are hungry.
