Neuropsychological correlates of impaired emotion recognition  following traumatic brain injury.
Previous research has shown that individuals with traumatic brain injury (TBI) are significantly impaired on emotion recognition tasks. In this study, the relationship between neuropsychological functioning and emotion recognition was examined in 11 individuals with moderate to severe TBI and a control group of 13 individuals matched for age,sex, and education. Emotion recognition stimuli were from Ekman and Friesen's pictures of facial affect. The group with TBI showed neuropsychological deficits consistent with those commonly found following moderate to severe TBI. The group with TBI also identified significantly fewer emotion recognition stimuli than the control group. The number of correctly identified emotion recognition stimuli was significantly correlated with measures of verbal cognitive processing in the group with TBI. These findings suggest that the role of left hemisphere brain mechanisms in the recognition of facial (nonverbal)emotion may be more important than previously recognized.
