A diffusion model account of the transfer-of-training effect

Abstract

We revisit a transfer-of-training study to analyze the data with a cognitive model. Fitting a diffusion model to participant behavior over sessions allows conclusions as to the underlying causes of behavioral changes---be they changes in cognitive strategies, adaptation to the paradigm, increasing familiarity with the stimuli, or speed of information processing. Our diffusion model analysis revealed that participants simultaneously adapt speed-accuracy trade-off, increase their non-decisional response speed, and increase their speed of information processing. All three of these adaptations transferred to a similar, non-trained outcome task.
