Individuals with high levels of alexithymia, a personality trait marked by difficulties in identifying and describing feelings and an externally oriented style of thinking, appear to require more time to accurately recognize intense emotional facial expressions (EFEs). However, in everyday life, EFEs are displayed at different levels of intensity and individuals with high alexithymia may also need more emotional intensity to identify EFEs. Nevertheless, the impact of alexithymia on the identification of EFEs, which vary in emotional intensity, has largely been neglected. To address this, two experiments were conducted in which participants with low (LA) and high (HA) levels of alexithymia were assessed in their ability to identify static (Experiment 1) and dynamic (Experiment 2) morphed faces ranging from neutral to intense EFEs. Results showed that HA needed more emotional intensity than LA to identify static fearful - but not happy or disgusted - faces. On the contrary, no evidence was found that alexithymia affected the identification of dynamic EFEs. These results extend current literature suggesting that alexithymia is related to the need for more perceptual information to identify static fearful EFEs.
述情障碍水平较高的个体，其人格特质表现为难以识别和描述情感以及具有外向型思维方式，他们似乎需要更多时间来准确识别强烈的情感面部表情（EFE）。然而，在日常生活中，EFE以不同强度呈现，述情障碍水平高的个体可能也需要更高的情感强度来识别EFE。尽管如此，述情障碍对识别情感强度各异的EFE的影响在很大程度上被忽视了。为解决这一问题，进行了两项实验，在实验中评估了述情障碍水平低（LA）和高（HA）的参与者识别从中性到强烈EFE的静态（实验1）和动态（实验2）变形面孔的能力。结果表明，与LA相比，HA识别静态恐惧面孔（而非快乐或厌恶面孔）需要更高的情感强度。相反，没有证据表明述情障碍会影响动态EFE的识别。这些结果扩展了当前的文献，表明述情障碍与识别静态恐惧EFE需要更多感知信息有关。
