Event Abstract Back to Event Object information in the brain Chris Davis1*, Tim Paris1, Bronson Harry2 and Jeesun Kim1 1 University of Western Sydney, MARCS Institute, Australia 2 Bangor University, School of Psychology, United Kingdom We used a gradual ‘unmasking’ procedure and functional magnetic resonance imaging of twelve participants to study the processing of gradually revealed primed and non-primed objects. Objects belonged to several board categories (e.g., buildings, faces, shoes) and the participant’s task was to correctly classify the object as it was slowly unmasked (accuracy was emphasized). Priming was induced by pre-exposing participants to non-degraded images. To determine at what stage and which brain regions process information about stimuli we used machine learning algorithms to classify the ensemble voxel activation patterns with respect to the labelled object categories. We found a priming effect on the object classification latencies that was partially mirrored in voxel activation patterns. Further, the machine classification results suggest that information about an object’s category is available before overt recognition.
