Visual and visuomotor perceptual learning: two distinct mechanisms

We investigated if visual and visuomotor perceptual learning rely on the same underlying mechanisms. Observers trained with line bisection stimuli in which a center line was either closer to a right or left outer line. In the visuomotor learning condition, observers adjusted the center line with the computer mouse to the smallest offset they could perceive. In the visual learning condition, observers indicated in a binary task if the center line was closer to left or right outer line. Learning occurred in both conditions. Interestingly, improvements in either condition did not transfer to the other condition as shown by pre- and post-measurements (i.e. visuomotor learning did not improve visual performance and visual learning did not improve visuomotor performance). Our results suggest that visual and visuomotor perceptual learning rely on different mechanisms.
