Abstract

In this study, we investigated a question about a possibility to form involuntary auditory-visual associations in children (8-11 yrs) during discriminations of speech sounds (phonemes) when they presented simultaneously with visual stimuli. It was used two types of static images - geometrical figures and images of hand gestures. We judge about the formation of auditory-visual association by behavioral disturbance (reaction time, percentage of wrong reactions during discriminations of phonemes) after changes in experimental protocol viz, partial substitution of preceding pairs of stimuli which were used during training to form auditory-visual associations for the new combinations of previous images and sounds. We find that in research conditions comparatively fast formed pronounced auditory-visual association; however features of response to mismatch stimuli in comparison with adults make to suggest the relative immaturity ofneurons of social perception in children.

摘要

在本研究中,我们调查了一个问题,即在对语音(音素)进行辨别时,8至11岁的儿童在同时呈现视觉刺激的情况下,是否有可能形成非自愿的视听关联。使用了两种类型的静态图像——几何图形和手势图像。我们通过在实验方案改变后(即部分替换训练期间用于形成视听关联的先前刺激对,代之以先前图像和声音的新组合)的行为干扰(反应时间、音素辨别期间错误反应的百分比)来判断视听关联的形成。我们发现,在研究条件下,相对快速地形成了明显的视听关联;然而,与成年人相比,对不匹配刺激的反应特征表明儿童社会感知神经元相对不成熟。
