Studies of facial affect recognition by people with traumatic brain injury (TBI) have shown this to be a significant problem. Vocal affect recognition also appears to be challenging for this population, but little is known about the degree to which one modality is impaired compared to the other. This study compared facial and vocal affect recognition of high and low intensity emotion expressions in people with moderate-to-severe TBI.
The Diagnostic Analysis of Nonverbal Accuracy-2 (Adult Faces; Voices) was administered to 203 participants with TBI.
Adults with TBI identified vocal emotion expressions with greater accuracy than facial emotion expressions. Facial affect recognition impairment was identified in 34% of participants, 22% were classified as having vocal affect recognition impairment and 15% showed impairment in both modalities. Participants were significantly less accurate at identifying low vs high intensity emotion expressions in both modalities. Happy facial expressions were significantly better identified than all other emotions. Errors were distributed across the emotion categories for vocal expressions.
The degree of facial affect impairment was significantly greater than vocal affect impairment in this sample of people with moderate-to-severe TBI. Low intensity emotion expressions were particularly problematic and an advantage for positively valenced facial emotion expressions was indicated.
对创伤性脑损伤（TBI）患者面部表情识别的研究表明，这是一个重大问题。语音情感识别对这一人群来说似乎也具有挑战性，但对于一种模态相对于另一种模态受损的程度知之甚少。本研究比较了中重度TBI患者对高强度和低强度情感表达的面部和语音情感识别。
对203名TBI患者进行了非言语准确性诊断分析-2（成人面孔；声音）测试。
TBI成人患者识别语音情感表达的准确性高于面部情感表达。34%的参与者被确定存在面部情感识别障碍，22%被归类为存在语音情感识别障碍，15%在两种模态上均表现出障碍。在两种模态中，参与者识别低强度与高强度情感表达的准确性明显较低。快乐的面部表情比所有其他情绪的识别效果明显更好。语音表达的错误分布在各个情绪类别中。
在这个中重度TBI患者样本中，面部情感障碍的程度明显大于语音情感障碍。低强度情感表达尤其成问题，并且表明了积极价态面部情感表达的优势。
