Changes in social and emotional behaviour have been consistently observed in patients withtraumatic brain injury. These changes are associated with emotion recognition deficits whichrepresent one of the major barriers to a successful familiar and social reintegration. In the presentstudy, 32 patients with traumatic brain injury, involving the frontal lobe, and 41 age- andeducation-matched healthy controls were analyzed. A Go/No-Go task was designed, where eachparticipant had to recognize faces representing three social emotions (arrogance, guilt andjealousy). Results suggested that ability to recognize two social emotions (arrogance and jealousy)was significantly reduced in patients with traumatic brain injury, indicating frontal lesion can reduceemotion recognition ability. In addition, the analysis of the results for hemispheric lesion location(right, left or bilateral) suggested the bilateral lesion sub-group showed a lower accuracy on allsocial emotions.
