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.
