Whereas a reduced tendency to follow pointing gestures is described as an early sign of autism, the literature on response to joint attention indicates that autistic children perform better when a point is added to other social cues such as eye gaze. The purpose of this study was to explore pointing processing in autism when it is the only available cue and to investigate whether autistic children discriminate intentional pointing gestures from incidental pointing gestures. Eye movements of 58 autistic children (48 male) and 61 typically developing children (36 male) aged 3–5 years were recorded as the children were watching videos of a person uttering a pseudoword and pointing intentionally with one hand and incidentally with the other hand. After 3 s, two different potential referents for the pseudoword gradually emerged in both pointed-at corners. In comparison with typically developing children, autistic children’s fixations were significantly farther away from both pointed-at zones. Upon hearing a novel word, typically developing children shifted their visual attention toward the zone pointed intentionally. This trend did not emerge in the group of autistic children regardless of their level of vocabulary. Autistic children, independently of their level of language, pay little attention to pointing when no other social cues are available and fail to discriminate intentional pointing gestures from incidental ones. They seem to grasp neither the spatial nor the social value of pointing.

关注自闭症儿童的有意与偶然指向手势:一项眼动追踪研究

虽然遵循指示手势的倾向减少被描述为自闭症的早期迹象,但有关对共同注意反应的文献表明,当一个点被添加到其他社会线索(如眼睛注视)时,自闭症儿童的表现会更好。本研究的目的是探索孤独症的指向加工,当它是唯一可用的线索时,并调查自闭症儿童是否区分有意指向手势和偶然指向手势。记录了 58 名自闭症儿童(48 名男性)和 61 名正常发育儿童(36 名男性)的眼动,这些儿童正在观看一个人说假词并用一只手故意指着另一只手的视频. 3 秒后,伪词的两个不同的潜在指称逐渐出现在两个尖角。与正常发育的儿童相比,自闭症儿童的注视距离两个指向区都远得多。在听到一个新词时,典型的发育中的儿童将他们的视觉注意力转移到有意指向的区域。无论他们的词汇水平如何,这种趋势都没有出现在自闭症儿童群体中。自闭症儿童,无论他们的语言水平如何,在没有其他社交线索可用时很少注意指向,并且无法区分有意的指向手势和偶然的手势。他们似乎既没有把握指向的空间价值,也没有把握指向的社会价值。自闭症儿童的注视明显远离两个指向区域。在听到一个新词时,典型的发育中的儿童将他们的视觉注意力转移到有意指向的区域。无论他们的词汇水平如何,这种趋势都没有出现在自闭症儿童群体中。自闭症儿童,无论他们的语言水平如何,在没有其他社交线索可用时很少注意指向,并且无法区分有意的指向手势和偶然的手势。他们似乎既没有把握指向的空间价值,也没有把握指向的社会价值。自闭症儿童的注视明显远离两个指向区域。在听到一个新词时,典型的发育中的儿童将他们的视觉注意力转移到有意指向的区域。无论他们的词汇水平如何,这种趋势都没有出现在自闭症儿童群体中。自闭症儿童,与他们的语言水平无关,在没有其他社交线索可用时很少注意指向,并且无法区分有意的指向手势和偶然的手势。他们似乎既没有把握指向的空间价值,也没有把握指向的社会价值。无论他们的词汇水平如何,这种趋势都没有出现在自闭症儿童群体中。自闭症儿童,无论他们的语言水平如何,在没有其他社交线索可用时很少注意指向,并且无法区分有意的指向手势和偶然的手势。他们似乎既没有把握指向的空间价值,也没有把握指向的社会价值。无论他们的词汇水平如何,这种趋势都没有出现在自闭症儿童群体中。自闭症儿童,无论他们的语言水平如何,在没有其他社交线索可用时很少注意指向,并且无法区分有意的指向手势和偶然的手势。他们似乎既没有把握指向的空间价值,也没有把握指向的社会价值。
