At the outset we should emphasize that nothing in Hayward and Tarr’s commentary speaks to the main results of the Biederman and Bar (1999) report: Slight costs of rotation in detecting geon differences when matching a sequential pair of novel objects (3.3% increase in error rates), but massive costs (46.2% increase in error rates) in the detection of metric differences. Their comments are all a...

Differing views on views: comments on Biederman and Bar (1999)

In a recent article, Biederman and Bar (1999) present several results to support ‘‘a class of theories [that] assumes that non-accidental properties (NAPS) might be exploited so that even novel objects can be recognized under depth rotation’’ — specifically, theories based on ‘geons’ (Biederman, 1987; Hummel & Biederman, 1992). Biederman and Bar likewise present results that they believe to be ...
