No evidence that late-sighted individuals rely more on color for object recognition: Reply to Vogelsang et al.

Vogelsang et al. (1) claim that individuals treated for congenital blindness via cataract removal surgery (Prakash patients) rely more on color cues for object recognition than age-matched controls. The evidence presented for this claim is based on an inappropriate statistical analysis of proportion data in a recognition task. We show that a variety of more suitable analyses provide, if anything, slight evidence in favor of the null hypothesis that patients and controls are similarly impaired by the removal of color information in an object recognition task.
