Facial expression processing and the attribution of facial emotions to a context were investigated in adults with Down syndrome (DS) in two experiments. Their performances were compared with those of a child control group matched for receptive vocabulary. The ability to process faces without emotional content was controlled for, and no differences appeared between the two groups. Specific impairments were found in the DS group according to the task modalities and the type of facial emotional expressions. In the emotion matching condition, the DS adults showed overall difficulties whereas in the identification and recognition conditions they were particularly impaired when processing the neutral expression. In the emotion attribution task, they exhibited difficulties with the sad expression only and the analysis of their error pattern revealed that they rarely selected this expression throughout the task. The sad emotion was the only one that showed a significant relationship with the facial expression processing tasks.
在两项实验中，对患有唐氏综合征（DS）的成年人的面部表情处理以及面部情绪在特定情境中的归因进行了研究。将他们的表现与接受性词汇量匹配的儿童对照组进行了比较。对处理无情感内容面孔的能力进行了控制，两组之间未出现差异。根据任务模式和面部情绪表达类型，在DS组中发现了特定的损伤。在情绪匹配条件下，DS成年人总体上存在困难，而在识别和辨认条件下，他们在处理中性表情时尤其受损。在情绪归因任务中，他们仅在处理悲伤表情时存在困难，对其错误模式的分析表明，在整个任务过程中他们很少选择这种表情。悲伤情绪是唯一与面部表情处理任务存在显著关联的情绪。
