Performance Factors in Associative Learning: Assessment of the Sometimes Competing Retrieval Model

The sometimes competing retrieval model (SOCR; Stout & Miller, 2007), was applied to various phenomena in Pavlovian conditioning in the current simulations in order to assess the model's ability to predict behavioral responses in each condition. Simulation 1 applied SOCR to basic acquisition, including massive training producing the overtraining effect, and the subsequent decrement of this effect when context changes. In Simulation 2, SOCR was applied to basic extinction and renewal. Simulation 3 compared SOCR to feature negative training. In Simulation 4, SOCR predicted that conditioned inhibition following feature-negative and differential conditioning depends on the inter-trial interval. In, Simulation 5 SOCR predicted presentations of the inhibitor alone would be inadequate to extinguish condition inhibition. In Simulation 6 general cue competition phenomena were simulated. In Simulation 7, SOCR predicted inhibitors gain more behavioral control than excitors after compound training. Finally, in Simulation 8 SOCR anticipated slower acquisition after CS-weak shock pairings.
