【摘要】：目前,国内外从神经语言学角度对弱智儿童情感韵律的研究还处于初始阶段,我们对这一特殊群体在情感韵律中的表现还知之甚少。本研究用提取声学参数的方法对弱智儿童的情感韵律进行研究,通过两个实验探究了以汉语为母语的弱智儿童的情感韵律表现情况,并在此基础上讨论这一特殊群体韵律表现背后的原因。实验共分两个部分：第一部分采用故事讲述任务,通过与实际年龄匹配的正常儿童比较,考查18名弱智儿童被试的情感韵律表现情况。实验结果显示：弱智儿童在音高范围和元音平均时长上均与正常儿童存在显著性差异,而且弱智儿童的平均音高和元音平均时长的标准差要大于正常儿童,表现出了一定的非典型性特征。第二部分用同样的实验方法,通过与语言能力匹配组的正常儿童进行比较,看弱智儿童的情感韵律表现情况。实验结果显示：两组被试在平均音高和音高范围上都有差异,在元音平均时长上没有差异,但是弱智儿童平均音高和元音平均时长的标准差要大。两个实验结果均表明：弱智儿童的情感韵律存在一定程度的损伤,在音高和元音平均时长上都有表现。本文还在前两个实验的基础上比较了两组正常儿童的情感韵律表现情况,结果发现：两组正常儿童在音高范围和平均音高上没有差异,在元音时长上却存在显著性差异。这在某种程度上表明,弱智儿童在元音时长上的非典型性特征并非是其特异性损伤。本文对弱智儿童情感韵律损伤原因进行了探讨。可以发现,造成弱智儿童情感韵律损伤的原因是多方面的,既有神经病理上的因素,也有神经认知上的影响。本研究还根据实验结果对弱智儿童教育教学提出了一些建议。
[Abstract]:At present, the research on emotional prosody of mentally retarded children from the perspective of neurolinguistics at home and abroad is still in the initial stage. We know very little about the performance of this special group in emotional prosody. In this study, we used the method of extracting acoustic parameters to study the emotional prosody of mentally retarded children. Through two experiments, this paper probes into the expression of emotional prosody of mentally retarded children who speak Chinese as their mother tongue, and discusses the reasons behind the prosodic performance of this special group. The experiment is divided into two parts: in the first part, the story telling task is used to compare with the normal children matched with the actual age. The results showed that there were significant differences in pitch range and vowel duration between children with mental retardation and normal children. Moreover, the standard deviation of average pitch and vowel length of mentally retarded children is larger than that of normal children, showing some atypical characteristics. The second part uses the same experimental method. By comparing with the normal children in the language ability matching group, we looked at the emotional prosody performance of the mentally retarded children. The results showed that there were differences in the average pitch and pitch range between the two groups. There is no difference in the average vowel duration, but the standard deviation of the average pitch and the average vowel length of the mentally retarded children is large. The two experimental results show that the emotional prosody of the mentally retarded children is damaged to some extent. We also compared the emotional prosody performance of the two groups of normal children on the basis of the first two experiments. The results showed that there was no difference in pitch range and average pitch between the two groups, but there was significant difference in vowel duration. The atypical feature of vowel duration in children with mental retardation is not its specific injury. This paper discusses the causes of emotional prosody injury in mentally retarded children. It can be found that there are many reasons for emotional prosody injury in children with mental retardation, and there are neuropathic factors. According to the experimental results, some suggestions are made for the education and teaching of mentally handicapped children.
