Document Summary
Chapter 5: drive theory and motivational psychology: sheffield et al. research showed: organisms will learn a response to obtain sweet-tasting liquid having no caloric value, and thus no drive is reduced. Drtrf (drive-reduction theory of reinforcement: according to sheffield, any response that leads to an increase in motivation (stimuli) is reinforced. Ditrf (drive- induction theory of reinforcement): for hull learning requires drive reduction. However, sheffield showed that learning can occur without reduction in drive. Thorndike pavlov watson skinner: learning: several types of learning influence the development of motives. Motivated behaviours are acquired or directed by learning: pavlovian or respondent conditioning: a procedure whereby formerly neutral stimuli gain control over behaviour. Through a pairing procedure of cs (tone) and ucs (food), the cs motivates the organism to respond in a manner similar to the way it responds to the ucs. Albert revealed that a 9-11 month old child could form a conditioned emotional reaction to previously neutral stimuli.
