case of W.J who had strokes so got prospagnosia. Could not select famous faces from normal ones. Went into sheep farming but could recognise those individually. Shows FRU was lost. Must be another animal system or they fall under objects.
One women who had prosopagnesia and couldnt tell what sex they were. Could tell what phonemes were being mouthed in photos. Suggests facial speech analysis was good but not structural encoding or direct visual processing. Supports the model as shows they are seperate.
5 patients with brain injurieswho looked at faces with changed features. 4 couldnt tell what was different but 1 could. When told what to look for 2 out the 4 improves. Concluded that the FFA was damaged and plays a big role in understanding faces.
