A distinction concerning vision-for-action and affordance perception.

ABSTRACT

In this paper, I offer a discussion concerning the conceptual connection between the notion of vision-for-action and the one of affordance perception. I first analyze the notion of vision-for-action. I then analyze a notion usually coupled with it the notion of affordance perception, the main insights behind which are guiding several current neuroscientific enterprises and the related philosophical speculations. Then, I argue that we should not couple these two notions with a light heart though these two processes can be, from a theoretical point of view, related, we should be careful in inferring the actual and effective occurrence of the latter in the presence of the former. This will be done by carrying out a conceptual analysis of the experimental evidence coming from the 'Two Visual Systems Model', which is the main reference in the literature on affordance perception and vision-for-action. My point has strong philosophical implications for our view concerning the best interpretation of how vision-for-action really works, and the specific relation it actually entertains with affordance perception.
