Background:
Behavioural changes are often reported after a severe traumatic brain injury (TBI). These changes are usually a greater burden for relatives than physical or cognitive impairments. This study investigated social cognition in TBI patients using two theory of mind (TOM) tasks.
Method:
The performances of 17 patients with severe TBI and 17 matched controls were compared on two tasks designed to investigate understanding of other people's mental states: The 'Reading the Mind in the Eyes' test (RME) and the 'Character Intention Task' (CIT). TBI patients and controls were also given several executive function tasks.
Results:
Compared to healthy controls, patients were impaired in most executive tests and in both TOM tasks. No relationship was found between TOM and executive measures. This is consistent with Rowe's position, who suggested an independence between executive functioning and social cognition. These data suggest that TBI patients may have specific social intelligence disturbances.
Conclusion:
Future work should employ additional tests of TOM and behavioural ratings and recruit more patients in order to complete analysis.
