Viewpoint Dependence in Scene Recognition

Abstract

Two experiments investigated the viewpoint dependence of spatial memories In Experiment 1, participants learned the locations of objects on a desktop from a single perspective and then took part in a recognition test, test scenes included familiar and novel views of the layout Recognition latency was a linear function of the angular distance between a test view and the study view In Experiment 2, participants studied a layout from a single view and then learned to recognize the layout from three additional training views A final recognition test showed that the study view and the training views were represented in memory, and that latency was a linear function of the angular distance to the nearest study or training view These results indicate that interobject spatial relations are encoded in a viewpoint-dependent manner, and that recognition of novel views requires normalization to the most similar representation in memory These findings parallel recent results in visual object recognition.
