Differing views on views: comments on Biederman and Bar (1999).
No full textIn 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 and Hummel & Biederman, 1992). Biederman and Bar likewise present results that they believe to be inconsistent with a “class of theories … based on generalization from templates specified by metric properties” — specifically, ‘view-based’ or ‘image-based’ theories (Bricolo, Poggio & Logothetis, 1997,Poggio & Edelman, 1990, Tarr & Bülthoff, 1995 and Tarr & Bülthoff, 1998). Because our disagreements with Biederman's theoretical approach have been detailed in many other forums (Hayward & Tarr, 1997, Tarr & Bülthoff, 1995 and Tarr & Bülthoff, 1998) we do not feel it is necessary to respond in kind. We do feel, however, that it is necessary to address a series of straightforwardly incorrect claims made by Biederman and Bar regarding our published results. Below we enumerate these claims, and our replies to each2:</p

Mechanisms of top-down facilitation in perception of visual objects studied by fMRI
Full text linkPrior knowledge regarding the possible identity of an object facilitates its recognition from a degraded visual input, though the underlying mechanisms are unclear. Previous work implicated ventral visual cortex but did not disambiguate whether activity-changes in these regions are causal to or merely reflect an effect of facilitated recognition. We used functional magnetic resonance imaging to study top-down influences on processing of gradually revealed objects, by preceding each object with a name that was congruent or incongruent with the object. Congruently primed objects were recognized earlier than incongruently primed, and this was paralleled by shifts in activation profiles for ventral visual, parietal, and prefrontal cortices. Prior to recognition, defined on a trial-by-trial basis, activity in ventral visual cortex rose gradually but equivalently for congruently and incongruently primed objects. In contrast, prerecognition activity was greater with congruent priming in lateral parietal, retrosplenial, and lateral prefrontal cortices, whereas functional coupling between parietal and ventral visual (and also left lateral prefrontal and parietal) cortices was enhanced in the same context. Thus, when controlling for recognition point and stimulus information, activity in ventral visual cortex mirrors recognition success, independent of condition. Facilitation by top-down cues involves lateral parietal cortex interacting with ventral visual areas, potentially explaining why parietal lesions can lead to deficits in recognizing degraded objects even in the context of top-down knowledge
