述情障碍涉及识别和交流自己情绪的困难，以及外向思维的倾向。最近的研究认为，这种述情障碍是由于唤醒反应改变和对“客观”唤醒反应的主观意识较差造成的。尽管一般人群在识别和描述情绪方面存在个体差异，但现有的研究主要集中在高度述情障碍的个体上。在这里，我们研究了平均唤醒度以及主观和客观唤醒度之间的一致性是否支撑了一般人群样本中述情障碍特征的个体差异。参与者对来自国际情感图片系统的 60 张图像进行主观唤醒反应评分，同时记录他们的皮肤电导。自闭症商数用于控制一般人群的自闭症特征。使用线性模型的分析表明，平均唤醒显着预测多伦多述情障碍评分高于自闭症特征，但一致性评分却没有。这表明，虽然客观唤醒对于高于和低于述情障碍临界值的人群来说是一个有用的预测因子，但客观和主观唤醒之间的一致性分数并不能预测一般人群中述情特征的变化。
Alexithymia concerns a difficulty identifying and communicating one’s own emotions, and a tendency towards externally-oriented thinking. Recent work argues that such alexithymic traits are due to altered arousal response and poor subjective awareness of “objective” arousal responses. Although there are individual differences within the general population in identifying and describing emotions, extant research has focused on highly alexithymic individuals. Here we investigated whether mean arousal and concordance between subjective and objective arousal underpin individual differences in alexithymic traits in a general population sample. Participants rated subjective arousal responses to 60 images from the International Affective Picture System whilst their skin conductance was recorded. The Autism Quotient was employed to control for autistic traits in the general population. Analysis using linear models demonstrated that mean arousal significantly predicted Toronto Alexithymia Scale scores above and beyond autistic traits, but concordance scores did not. This indicates that, whilst objective arousal is a useful predictor in populations that are both above and below the cut-off values for alexithymia, concordance scores between objective and subjective arousal do not predict variation in alexithymic traits in the general population.
