The Perception/Cognition Divide in Predictive Models of the Mind
24 maggio 2018, h. 14:30-16:30
Sala Enzo Paci, Direzione del Dipartimento di Filosofia, via Festa del Perdono 7.
According to predictive models, perception is a hierarchical and predictive process: instead of sensory signals being processed in a bottom-up fashion, they are compared to inner predictions at different levels of processing. Many, such as Andy Clark, but also Friston, Frith, or Lupyan, point out that such a model “makes the lines between perception and cognition fuzzy… In place of any real distinction between perception and belief we now get variable differences in the mixture of top-down and bottom-up influences". This, in turn, has been taken to imply that perception is through and through cognitively penetrated, or that the very idea of 'cognitive penetration' ceases to be relevant. Here, i will argue that these diagnoses comes from looking in the wrong place: focusing on our recent work on top-down influences in face perception, i will suggest that the perception/cognition divide still needs to be drawn, even if one adopts predictive models of the effects, because of two distinctive characters of cognition.
