The Rescorla–Wagner model ("R-W") is a model of classical conditioning, in which learning is conceptualized in terms of associations between conditioned (CS) and unconditioned (US) stimuli. A strong CS-US association means that the CS signals predict the US. One might say that before conditioning, the subject is surprised by the US, but after conditioning, the subject is no longer surprised, because the CS predicts the coming of the US. The model casts the conditioning processes into discrete trials, during which stimuli may be either present or absent. The strength of prediction of the US on a trial can be represented as the summed associative strengths of all CSs present during the trial. This feature of the model represented a major advance over previous models, and it allowed a straigh

- 레스콜라-와그너 모델(Rescorla- Wagner model) 또는 'R-W 모델'은 고전적 조건형성 모델로, 조건부(CS)와 무조건부(US) 자극 간의 연관성 측면에서 학습이 개념화된다. 강력한 CS-US 협동작용은 본질적으로 CS가 US을 신호하거나 예측한다는 것을 의미한다. 컨디셔닝하기 전에 피험자는 US에 놀랐지만 컨디셔닝 후에 CS가 US의 도래를 예측하기 때문에 피험자는 더 이상 놀라지 않을 것이라고 말할 수 있다. 이 모델은 컨디셔닝 프로세스를 개별 시험으로 캐스트하며,이 동안 자극이 존재하거나 부재할 수 있다. 시험에서 US의 예측 강도는 시험 동안 존재하는 모든 CS의 합쳐진 결합 강도로 표현 될 수있다. 이 모델의 기능은 이전 모델보다 크게 발전했으며 중요한 실험 현상, 특히 이로써 차단 효과에 대한 보다 효과적인 설명이 가능해졌다. 이 모델의 제안으로 인해 확장되고 연관된 수정, 대체 모델 및 많은 추가 결과가 발생했다. 일례로 한 연구에서는 "중뇌의 중배엽 DA 투영에서 도파민 뉴런의 위상 활동이 모델에 자세히 설명된 예측 오류 유형을 인코딩한다"고 제안한 것처럼 이 모델은 최근 몇 년 동안 신경 과학에 영향을 미쳤다.레스콜라-와그너(Rescorla–Wagner) 모델은 1972년 심리학자 (Robert A.

- The Rescorla–Wagner model ("R-W") is a model of classical conditioning, in which learning is conceptualized in terms of associations between conditioned (CS) and unconditioned (US) stimuli. A strong CS-US association means that the CS signals predict the US. One might say that before conditioning, the subject is surprised by the US, but after conditioning, the subject is no longer surprised, because the CS predicts the coming of the US. The model casts the conditioning processes into discrete trials, during which stimuli may be either present or absent. The strength of prediction of the US on a trial can be represented as the summed associative strengths of all CSs present during the trial. This feature of the model represented a major advance over previous models, and it allowed a straightforward explanation of important experimental phenomena, most notably the blocking effect. Failures of the model have led to modifications, alternative models, and many additional findings. The model has had some impact on neural science in recent years, as studies have suggested that the phasic activity of dopamine neurons in mesostriatal DA projections in the midbrain encodes for the type of prediction error detailed in the model. The Rescorla–Wagner model was created by Yale psychologists Robert A. Rescorla and Allan R. Wagner in 1972. (en)

- Het Rescorla-Wagnermodel is een theoretisch uitgangspunt voor onderzoek in de gedragswetenschap. Robert A. Rescorla (1940) en Allan R. Wagner (1934) zijn twee Amerikaanse leerpsychologen die een nieuwe draai gaven aan de theorie van de operante conditionering, een behavioristisch model opgesteld door Burrhus Skinner. In de jaren zeventig deelden de twee psychologen een taxi naar een New Yorks forum over behaviorisme. Tijdens de rit raakten ze aan de praat en tot hun verbijstering bleek dat ze allebei aan dezelfde theorie werkten, een theorie die ongerijmdheden in Skinners werk hoopte te verklaren. Door hun bevindingen te vergelijken ontstond het Rescorla-Wagnermodel, een model van de klassieke conditionering waarin een verklaring wordt gezocht van het leerproces van een dier tijdens dierproeven in de Skinner-box. Rescorla en Wagner stelden dat leergedrag enkel optreedt bij een discrepantie tussen wat verwacht wordt en wat gebeurt. Tijdens dit 'trial-level model' is elke stimulus ofwel aanwezig ofwel afwezig in de proef. De verwachting van de (Unconditioned Stimulus ofwel US) kan wiskundig voorgesteld worden als de som van de associatieve sterktes van de aanwezige (Conditioned stimuli = CS) tijdens de duur van de proef. Deze verhouding maakte korte metten met de onvolledigheid in eerdere modellen en bood een duidelijke verklaring voor onduidelijkheden zoals blokkering tijdens leerexperimenten. Het Rescorla-Wagnermodel werd het belangrijkste leermodel binnen het behaviorisme sinds Skinner en Pavlov. Het is echter slechts een theorie en is sinds de publicatie niet gevrijwaard van kritiek of tegenspraak. Ook Robert Rescorla en Allan Wagner hebben zich mettertijd gedistantieerd van het naar hen genoemde model, hoewel de laatste jaren door onderzoek is gebleken dat gefaseerde activiteit van dopamine-neuronen in de middenhersenen een verklaring kan bieden voor de voorspellingsafwijking in het model.
