Visuomotor robustness is based on integration not segregation.

How can we explain, that DF - a patient with a damaged ventral stream - can act normally in many everyday tasks despite her profound perceptual disability. The classical answer is that perception and action are based on separate visual streams. Here, I will explain why this view is problematic and offer an alternative answer. Specifically, I will argue that the preserved performance of DF should be seen as evidence of the redundancy of visuomotor control and not as evidence of a segregation between vision for perception and action.
