Short-latency ocular following in humans: sensitivity to binocular disparity.

abstract：:Studies of high-level models of visual object categorization have left unresolved issues of neurobiological relevance, including how features are extracted from the image and the role played by memory capacity in categorization performance. We compared the ability of a comprehensive set of models to match the categori...

Whether this asymmetry is also true of the mental representations of faces is not known.
