DIRECT EVIDENCE FOR ANALYTIC REPRESENTATIONS OF ATTENDED IMAGES AND HOLISTIC REPRESENTATIONS OF IGNORED IMAGES

Volker Thoma, John Hummel, Jules Davidoff

Attended images prime themselves and their left-right (mirror) reflections; ignored images prime themselves but not their reflections (Stankiewicz et al., 1998). These and other effects are predicted by a model that represents attended images both analytically and holistically, and ignored images holistically only (Hummel & Stankiewicz, 1996). The model also predicts that priming for attended images will generalize over configural distortions whereas priming for ignored images will not. Two experiments tested this prediction. In Experiment 1, attended split images primed their intact counterparts, whereas ignored split images did not. Experiment 2 demonstrated that a substantial component of the observed priming is specifically visual. These data provide direct support for the model's use of a hybrid analytic/holistic representation of object shape.
