Abstract:
The purpose of this study is to investigate the vocalization characteristics of infants with autism spectrum disorder (ASD) in the context of frustration. The duration and frequency of vocalization in 48 infants with ASD and 65 infants with typical development (TD) were followed up to 24 months later for subsequent diagnosis. The typical vocalizations of infants with ASD were retrospectively analyzed, such as speech-like vocalizations, nonspeech vocalizations, vocalizations towards the person and non-social vocalizations. The results showed that, compared with the TD group, vocalizations of infants with ASD during the still-face period had lower typical vocalizations and characteristics associated with social intention, and that these characteristics were closely related to the clinical symptoms of ASD, among which vocalizations towards the person accompanied by social intention had discriminative efficacy.
摘要:
目的探讨孤独症谱系障碍(ASD)婴幼儿在挫折背景下的发声特征。48名ASD婴儿和65名典型发育(TD)婴儿的发声持续时间和频率在24个月后进行随访,以进行后续诊断。回顾性分析ASD患儿典型发声情况,比如像语音一样的发声,非言语发声,对人的发声和非社会发声。结果表明,与TD组相比,在静止期,ASD婴儿的发声具有较低的典型发声和与社会意图相关的特征,这些特征与ASD的临床症状密切相关,其中对伴随社会意图的人的发声具有歧视性。
