Comparison of models on Svartdal (2008) experiment. In this comparison, no model shows a PREE (again based on ($\overline{\text{CRF}}-\overline{\text{PRF}}$)/($\overline{\text{CRF}}+\overline{\text{PRF}}$) correct choice responses). The AMT-alone model shows a counterintuitive negative to positive (acquisition to extinction) transition in correct choice performance for CRF versus PRF. Key: AMT associative mediation theory model, ATP = A(Aff)TP associative–affective two-process model, Data empirical data. Note: Data smoothed by second-order polynomial over all data points obtained by Svartdal (2008)
