许多研究已经证明，创伤性脑损伤（TBI）与基本情绪的识别缺陷、推断他人精神状态的能力（心智理论）以及执行功能的缺陷有关。然而，迄今为止还没有研究调查这三种构念在脑外伤背景下的关系。在目前的研究中，TBI参与者（N = 16）与人口统计学匹配的健康对照组（N = 17）进行了比较。结果发现，与对照组相比，TBI参与者对基本情绪的识别能力和心理状态归因能力显著降低。在这两项指标上的表现在健康对照组中有很强的相关性，但在TBI样本中没有。相比之下，在TBI（而不是对照组）样本中，心理理论与音素流畅性的表现基本相关，音素流畅性是一种执行功能的衡量标准，被认为对认知灵活性和自我调节提出了特殊要求。这些结果与其他证据一致，表明执行功能某些方面的缺陷可能至少部分地导致脑外伤后的社会认知缺陷，从而有助于解释脑外伤中社会功能障碍的普遍存在。(c) 2006 Elsevier Ltd.版权所有。
A number of studies have now documented that traumatic brain injury (TBI) is associated with deficits in the recognition of basic emotions, the capacity to infer mental states of others (theory of mind), as well as executive functioning. However, no study to date has investigated the relationship between these three constructs in the context of TBI. In the current study TBI participants (N = 16) were compared with demographically matched healthy controls (N = 17). It was found that TBI participants' recognition of basic emotions, as well as their capacity for mental state attribution, was significantly reduced relative to controls. Performance on both of these measures was strongly correlated in the healthy control, but not in the TBI sample. In contrast, in the TBI (but not the control) sample, theory of mind was substantially correlated with performance on phonemic fluency, a measure of executive functioning considered to impose particular demands upon cognitive flexibility and self-regulation. These results are consistent with other evidence indicating that deficits in some aspects of executive functioning may at least partially underlie deficits in social cognition following TBI, and thus help explain the prevalence of social dysfunction in TBI.
