We revisit a transfer-of-training study and analyze its data using a cognitive modeling approach. Fitting a diffusion model to participant behavior over sessions al- lows conclusions as to the underlying causes of behav- ioral changes—be they changes in cognitive strategies, adaptation to the paradigm, increasing familiarity with the stimuli, or speed of information processing. Our dif- fusion model analysis revealed that participants simul- taneously 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.
