The current study explored the judgments individuals with Substance Use Disorders (SUDs) make regarding the authenticity of enjoyment smiles and masking smiles containing traces of negative emotions. Accuracy at identifying the masked negative emotions were also examined. Eye-movements were recorded to observe relationships between attentional processes and smile judgment. Additionally, the relationships between smile judgment, emotion dysregulation, and interpersonal problems were investigated. Twenty individuals with SUDs and twenty individuals matched on gender/age participated in the smile judgment task. Results indicated that individuals with SUDs were no different in their categorization of smiles. However, the results showed that individuals with SUDs were significantly more likely to report the presence of negative emotions in the expressions. They were also more often incorrect in their identification of the masked emotions. No link was observed between smile judgment and attentional processes. Emotional and interpersonal functioning were related more to the ability to distinguish smile authenticity than the ability to identify masked emotions.

物质使用障碍中的微笑判断及其与人际关系和情绪功能的关系：一项眼动追踪研究。

当前的研究探索了物质使用障碍（SUD）个体对享受微笑和掩饰微笑的真实性做出的判断，这些微笑包含负面情绪的痕迹。还检查了识别被掩盖的负面情绪的准确性。记录眼动，观察注意过程和微笑判断之间的关系。此外，调查了微笑判断，情绪失调和人际关系之间的关系。20名具有SUD的人和20名性别/年龄相匹配的人参加了微笑判断任务。结果表明，SUD患者的微笑分类没有差异。然而，结果表明，患有SUD的人更有可能报告表达中存在负面情绪。他们在掩盖情感的识别中也常常不正确。在微笑判断和注意过程之间没有发现联系。情绪和人际交往功能与识别微笑真实性的能力有关，而不是与识别被掩盖的情绪有关。
