Abstract
Categorizing incoming visual information from our environment is essential for deciding how to react to situations. Visual search tasks provide evidence that early semantic categorization in the visual cortex occurs soon after the presentation of an image, biasing visual processing in favor of a specific category (Peelen, Fei-Fei & Kastner, 2009). Considering those findings, we incorporated an attentional control paradigm using an arbitrary cue to generate semantic expectancies. Using EEG recording, our results suggest that different magnitudes of activation in the visual cortex soon after the presentation of the arbitrary cue predict decisions to expect a broad semantic category.
