Children with autism spectrum disorder (ASD) may require interventions for communication difficulties. One type of intervention is picture communication symbols which are proposed to improve comprehension of linguistic input for children with ASD. However, atypical attention to faces and objects is widely reported across the autism spectrum for several types of stimuli.
In this study we used eye-tracking methodology to explore fixation duration and time taken to fixate on the object and face areas within picture communication symbols. Twenty-one children with ASD were compared with typically developing matched groups.
Children with ASD were shown to have similar fixation patterns on face and object areas compared with typically developing matched groups.
It is proposed that children with ASD attend to the images in a manner that does not differentiate them from typically developing individuals. Therefore children with and without autism have the same opportunity to encode the available information. We discuss what this may imply for interventions using picture symbols.
自闭症谱系障碍(ASD)儿童可能需要干预措施来解决沟通困难。干预措施之一是图片交流符号,它被认为可以提高自闭症儿童对语言输入的理解。然而,在自闭症谱系中,各种类型的刺激都广泛存在着对人脸和物体的异常关注。
在这项研究中,我们使用眼动追踪方法来探索自闭症儿童与对照组儿童在图片交流符号的对象和人脸区域的注视持续时间和注视时间。
与对照组相比,自闭症儿童在人脸和物体区域的注视模式相似。
研究提出,自闭症儿童的注视方式与对照组没有区别。因此,自闭症儿童和非自闭症儿童都有相同的机会对可用信息进行编码。我们讨论了这对使用图片符号进行干预的意义。
