工作背景：少数先前的研究提供了证据，表明可卡因使用者（CU）在复杂的社会认知任务中表现出障碍，而更基本的面部情绪识别则不受影响。然而，到目前为止，韵律和跨通道情绪加工在认知语言中还没有得到系统的研究。因此，本研究的目的是评估复杂的多感官情绪处理CU相比，控制和检查与药物使用模式的潜在关联。方法：简化版的综合情感测试系统（CATS-A）被用来测量情绪感知的三个渠道的面部影响，韵律，语义内容在58 CU和48名健康对照（HC）的年龄，性别，语言智力，和多年的教育相匹配。结果如下：CU在“情绪识别”和“韵律识别”的商数量表以及“韵律/意义冲突-注意韵律”和“情感韵律与情感面孔匹配”的分测验中，无论是注意韵律还是整合跨通道信息，得分均显著低于对照组。相比之下，在“情感识别商数”方面没有出现组间差异。可卡因的累积剂量和持续时间与情绪处理呈负相关。结论：CU显示受损的跨模态整合不同的情绪处理渠道，特别是关于韵律，而更基本的方面的情绪处理，如面部情感知觉的性能相比，HC。
Background: A small number of previous studies have provided evidence that cocaine users (CU) exhibit impairments in complex social cognition tasks, while the more basic facial emotion recognition is widely unaffected. However, prosody and cross-modal emotion processing has not been systematically investigated in CU so far. Therefore, the aim of the present study was to assess complex multisensory emotion processing in CU in comparison to controls and to examine a potential association with drug use patterns. Method: The abbreviated version of the comprehensive affect testing system (CATS-A) was used to measure emotion perception across the three channels of facial affect, prosody, and semantic content in 58 CU and 48 healthy control (HC) subjects who were matched for age, sex, verbal intelligence, and years of education. Results: CU had significantly lower scores than controls in the quotient scales of “emotion recognition” and “prosody recognition” and the subtests “conflicting prosody/meaning – attend to prosody” and “match emotional prosody to emotional face” either requiring to attend to prosody or to integrate cross-modal information. In contrast, no group difference emerged for the “affect recognition quotient.” Cumulative cocaine doses and duration of cocaine use correlated negatively with emotion processing. Conclusion: CU show impaired cross-modal integration of different emotion processing channels particularly with regard to prosody, whereas more basic aspects of emotion processing such as facial affect perception are comparable to the performance of HC.
