MODELLING FREE RECALL - A COMBINED ACTIVATION-BUFFER AND DISTRIBUTED-CONTEXT MODEL

摘要

A computational model of free recall is described, extending previous models by including both an activation buffer (Davelaar et al., 2005) and a distributed changing context representation (Howard and Kahana, 1999, 2002). The model was used to simulate published free-recall data, and to make new predictions for the role of context in continuous distractor free recall. A faster contextual change is predicted to cause a shift from primacy to recency, in comparison to a slower contextual change. An experiment was carried out, and results are consistent with this prediction.
