述情障碍是一种人格特征，与情绪识别和调节困难有关。目前尚不清楚这种缺陷是否主要是由于情绪的调节、感知或精神化造成的。为了阐明核心缺陷，我们对受试者进行了一系列情绪测试。我们预计高述情障碍症患者在所有任务中都表现不佳。两组健康个体分别在Bermond-Vorst述情障碍问卷的认知部分得分高和低，他们完成了情绪调节问卷，并执行了几项情绪加工任务，包括微表情识别任务、口语句子中情绪韵律和语义的识别任务、情绪和同一性学习任务以及冲突信念和情绪任务(情绪心理化)。两组在情绪调节问卷、伯克利表现力问卷和移情商数上存在差异。具体地说，情绪调节商数显示，述情障碍患者使用更多的压抑和较少的重新评估策略。在行为任务上，正如预期的那样，述情障碍者在微表情识别和情绪心理化方面表现较差。令人惊讶的是，群体在情绪语义、韵律和联想情绪学习任务上没有差异。述情障碍认知成分得分高的个体更倾向于采用抑制性情绪调节策略，而不是重新评价策略。在情绪信息加工方面，述情障碍与早期加工和高阶心理加工的成绩降低有关。然而，情绪化语言处理方面的困难并不是述情障碍组的核心缺陷。
Alexithymia, or “no words for feelings”, is a personality trait which is associated with difficulties in emotion recognition and regulation. It is unknown whether this deficit is due primarily to regulation, perception, or mentalizing of emotions. In order to shed light on the core deficit, we tested our subjects on a wide range of emotional tasks. We expected the high alexithymics to underperform on all tasks. Two groups of healthy individuals, high and low scoring on the cognitive component of the Bermond-Vorst Alexithymia Questionnaire, completed questionnaires of emotion regulation and performed several emotion processing tasks including a micro expression recognition task, recognition of emotional prosody and semantics in spoken sentences, an emotional and identity learning task and a conflicting beliefs and emotions task (emotional mentalizing). The two groups differed on the Emotion Regulation Questionnaire, Berkeley Expressivity Questionnaire and Empathy Quotient. Specifically, the Emotion Regulation Quotient showed that alexithymic individuals used more suppressive and less reappraisal strategies. On the behavioral tasks, as expected, alexithymics performed worse on recognition of micro expressions and emotional mentalizing. Surprisingly, groups did not differ on tasks of emotional semantics and prosody and associative emotional-learning. Individuals scoring high on the cognitive component of alexithymia are more prone to suppressive emotion regulation strategies rather than reappraisal strategies. Regarding emotional information processing, alexithymia is associated with reduced performance on measures of early processing as well as higher order mentalizing. However, difficulties in the processing of emotional language were not a core deficit in our alexithymic group.
