Differential outcomes effect : ウィキペディア英語版 | Differential outcomes effect
The Differential Outcomes Effect is a theory in Behaviorism, a branch of Psychology, that shows that a positive effect on accuracy occurs in discrimination learning between different stimuli when unique rewards are paired with each individual stimulus. The DOE was first discovered in 1970 by Milton Trapold on an experiment with rats, and was termed by Gail Peterson, Ruth Wheeler and Trapold in 1980. Since then it has been established through a myriad of experiments that the Differential Outcome Effect exists in most species capable of learning. ==Basic Definition== The Differential Outcomes Effect not only states that an association between a stimulus and a response is formed as traditional Classical Conditioning states, but that a simultaneous association is formed between a stimulus and a reinforcer in the subject. If one were to pair a stimulus with a reinforcer, that is known as a differential condition. When this is employed, one can expect a higher accuracy in tests when discriminating between two stimuli, due to this increased amount of information available to the subject than in a nondifferential condition.
