目的：高功能自闭症(HFA)患者在面部表情和韵律产生方面存在质的差异，很少被系统量化。作者的目标是定性和定量地分析HFA儿童和青少年的韵律和面部表情产生。方法：受试者为22名男性HFA儿童和青少年和18名典型发育期(TD)对照组(17名男性，1名女性)。作者使用故事复述任务来引出充满情感的叙事，并通过使用声学测量和知觉代码进行分析。结果：HFA组在面部表情的准确性和表现力上与TD组无显著差异，但显著高于TD组。HFA的参与者在他们的发声作品中明显更有表现力，有更大的笨拙的趋势。社交障碍的严重程度，如孤独症诊断观察表(ADOS；Lord，Rutter，DiLavore，&Risi，1999)所述，与更大的发声和面部笨拙相关。结论：患有HFA的参与者的面部和声音表情与TD同龄人一样可识别，但在性质上有所不同，特别是当听者编码具有完整动态特性的样本时。这些初步数据显示了非语言交际的质的差异，这些差异可能对HFA儿童和青少年的社交成功产生显著的负面影响。
Purpose: People with high-functioning autism (HFA) have qualitative differences in facial expression and prosody production, which are rarely systematically quantified. The authors' goals were to qualitatively and quantitatively analyze prosody and facial expression productions in children and adolescents with HFA.Method: Participants were 22 male children and adolescents with HFA and 18 typically developing (TD) controls (17 males, 1 female). The authors used a story retelling task to elicit emotionally laden narratives, which were analyzed through the use of acoustic measures and perceptual codes. Naive listeners coded all productions for emotion type, degree of expressiveness, and awkwardness.Results: The group with HFA was not significantly different in accuracy or expressiveness of facial productions, but was significantly more awkward than the TD group. Participants with HFA were significantly more expressive in their vocal productions, with a trend for greater awkwardness. Severity of social communication impairment, as captured by the Autism Diagnostic Observation Schedule (ADOS; Lord, Rutter, DiLavore, & Risi, 1999), was correlated with greater vocal and facial awkwardness.Conclusions: Facial and vocal expressions of participants with HFA were as recognizable as those of their TD peers but were qualitatively different, particularly when listeners coded samples with intact dynamic properties. These preliminary data show qualitative differences in nonverbal communication that may have significant negative impact on the social communication success of children and adolescents with HFA.
