Abstract

To date there has been little research concerning the neuropsychological mechanisms of emotion perception deficits following traumatic brain injury (TBI), although such deficits are well documented. This paper considers two major issues. First, are emotion-processing deficits found regardless of the media of presentation? In a recent study examining this issue, adults with severe TBI were found to have particular problems identifying emotions from conversational tone, as well as difficulties when presented with still photographs and audiovisual dynamic displays (videoed vignettes). They were relatively normal when asked to classify emotions on the basis of moving visual displays without sound. This may reflect the fact that the parietal cortices, important for processing movement, are relatively unscathed in TBI. The second issue concerns whether emotion recognition is facilitated by empathic emotional responses and whether these are diminished in people with TBI. Evidence is presented for a relation between subjective reports of diminished emotional experience and emotion recognition accuracy. Finally, preliminary data suggests that people with TBI may fail to have empathic reactions when asked to passively view emotional expressions.
