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.
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.
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.
Future work should employ additional tests of TOM and behavioural ratings and recruit more patients in order to complete analysis.
重度创伤性脑损伤（TBI）后常出现行为改变。相较于身体或认知障碍，这些改变通常给亲属带来更大负担。本研究使用两项心理理论（TOM）任务对TBI患者的社会认知进行了调查。
比较了17例重度TBI患者和17例匹配对照在两项旨在调查对他人心理状态理解的任务中的表现：“眼睛解读心理”测试（RME）和“角色意图任务”（CIT）。TBI患者和对照还接受了多项执行功能任务。
与健康对照相比，患者在大多数执行测试以及两项TOM任务中均表现受损。未发现TOM与执行测量之间存在关联。这与罗的观点一致，他认为执行功能与社会认知相互独立。这些数据表明TBI患者可能存在特定的社会智力障碍。
未来的研究应采用更多的TOM测试和行为评分，并招募更多患者以完成分析。
