Figure 7.

Discriminant component maps for one subject during the face-versus-car (top row) and red-versus-green (bottom row) discrimination tasks. In both tasks, the classifier was trained to discriminate between face and car trials. An early component was identified for both tasks, whereas a significant late component was only present for the face-versus-car categorization task. Red represents positive activity, and blue represents negative activity. Results shown are those of face trials with the mean of the car trials subtracted. All trials were aligned to the onset of visual stimulation, as indicated by the vertical black line at time 0, and sorted by response time. The black sigmoidal curves represent the subjects’ response times for each condition.
