Thirty years of Marr's Vision: Levels of Analysis in Cognitive Science

Thirty years after Marr’s landmark posthumous book, Vision (Marr, 1982), the argument for which he is most cited remains the distinction between computational, algorithmic and representational, and the implementation levels. In the interim, many reformulations of this basic distinction have been proposed, but is it still relevant? This symposium will discuss whether there is still a place for the algorithmic and representational level, with its cognitive-level concepts, given the rise in reductionist neuroscience from below and Bayesian analysis from above.
