虽然临床观察表明，述情障碍的个人有一个赤字，他们的能力，以识别情绪刺激，这种赤字是不是简单地由于在口头标签的问题，这两个假设还没有得到实证证实。在一项社区调查中，380名没有当前或过去精神疾病史的参与者完成了两项独立的述情障碍测量[情绪意识水平量表（LEAS）和多伦多述情障碍量表（TAS-20）1和情感知觉任务（PAT），一项140项匹配情绪刺激能力的测量。PAT包括四个子任务，要求受试者将言语或非言语情绪刺激与言语或非言语情绪反应相匹配。子任务包括句子匹配和单词匹配（verbal-verbal），面孔和话语（nonverbal-verbal），句子和面孔（语言-非语言），以及场景的面部和照片[非语言-非语言），在整个样本中，（述情障碍）TAS-20和较低的LEAS评分均与PAT每个子任务的准确率较低相关（p <0.001），分别解释方差的10.5%和18.4%。51例受试者符合TAS-20述情障碍标准。述情障碍者在纯非语言匹配、纯语言匹配和混合语言-非语言匹配上的得分低于其他受试者（所有p <0.001）。这些结果表明，述情障碍与情感刺激的言语和非言语识别受损有关，述情障碍的标志是难以将情感转化为文字，这可能是情感信息处理能力更普遍受损的标志。
Although clinical observations suggest that alexithymic individuals have a deficit in their ability to recognize emotional stimuli and that this deficit is not simply due to a problem in verbal labeling, these two hypotheses have not been empirically confirmed. Three hundred eighty participants in a community survey without current or past histories of psychiatric disorder completed two independent measures of alexithymia [the Levels of Emotional Awareness Scale (LEAS) and the Toronto Alexithymia Scale (TAS-20)1 and the Perception of Affect Task (PAT), a 140-item measure of the ability to match emotion stimuli. The PAT includes four subtasks that require the subject to match verbal or nonverbal emotion stimuli with verbal or nonverbal emotion responses. The subtasks include matching sentences and words (verbal-verbal), faces and words (nonverbal-verbal), sentences and faces (verbal-nonverbal), and faces and photographs of scenes [nonverbal-nonverbal), Across the entire sample, higher (alexithymic) TAS-20 and lower LEAS scores were both correlated with lower accuracy rates on each of the subtasks of the PAT (p < .001), accounting for 10.5% and 18.4% of the variance, respectively. Fifty-one subjects met TAS-20 criteria for alexithymia. Alexithymic individuals scored lower than other subjects on purely nonverbal matching, purely verbal matching, and mixed verbal-nonverbal matching (all p < .001). These results suggest that alexithymia is associated with impaired verbal and nonverbal recognition of emotion stimuli and that the hallmark of alexithymia, a difficulty in putting emotion into words, may be a marker of a more general impairment in the capacity for emotion information processing.
