Left hemisphere representations of emotional facial expressions
Researchers have suggested that the right hemisphere is superior at processing emotional facial expressions because it contains stored perceptual ‘templates’ of facial expressions. We tested each hemisphere of a split-brain patient on two tasks involving emotional facial expressions. Both hemisphere...

| description | Researchers have suggested that the right hemisphere is superior at processing emotional facial expressions because it contains stored perceptual ‘templates’ of facial expressions. We tested each hemisphere of a split-brain patient on two tasks involving emotional facial expressions. Both hemispheres performed equally well and significantly above chance matching facial expressions with emotion words. The subject's right hemisphere consistently performed well judging whether two facial expressions were the same or different. His left hemisphere performed poorly on this discrimination task at first, but showed a sharp improvement when the instructions were changed slightly, emphasizing verbal labels for the facial expressions. Results suggest that ‘facial expression templates’ may not be stored only on the right. |
