本研究采用眼动追踪的方法，考察了典型发育（TD）婴儿和2岁自闭症谱系障碍（ASD）儿童的预测推理能力。参与者观看了一个目标导向动作的视频，其中一个人类演员伸手抓住两个物体中的一个。在测试中，物体交换了位置。在这些事件中，我们测量了：视觉预期的行动结果与运动学线索（即，完成的到达行为）;没有运动学线索的动作结果的目标预测（即，不完整的范围）;以及延迟以生成跨这两个任务的预测。结果显示，当关于预期目标的轨迹信息存在时，各组的动作预期相似;然而，当预测没有运动学线索的目标时，发展和诊断差异变得明显。年幼的TD儿童产生的目标为基础的视觉预测，而年长的TD儿童在他们的视觉预测不系统。与TD组相比，ASD儿童产生基于位置的预测，这表明他们的视觉预测可能反映了视觉持续性。总之，这些结果表明早期预测推理能力的差异。目前的研究检查了对其他人的目标导向行为产生视觉预测的能力，特别是在患有和没有自闭症谱系障碍的婴儿和儿童中达到和抓住物体。结果显示，当关于一个人的目标的运动信息是明显的时，能力没有差异;然而，当依赖于先前的知识来生成视觉预测时，年龄和临床诊断的差异是明显的。
This study examined the predictive reasoning abilities of typically developing (TD) infants and 2-year-old children with autism spectrum disorder (ASD) in an eye-tracking paradigm. Participants watched a video of a goal-directed action in which a human actor reached for and grasped one of two objects. At test, the objects switched locations. Across these events, we measured: visual anticipation of the action outcome with kinematic cues (i.e., a completed reaching behavior); goal prediction of the action outcome without kinematic cues (i.e., an incomplete reach); and latencies to generate predictions across these two tasks. Results revealed similarities in action anticipation across groups when trajectory information regarding the intended goal was present; however, when predicting the goal without kinematic cues, developmental and diagnostic differences became evident. Younger TD children generated goal-based visual predictions, whereas older TD children were not systematic in their visual predictions. In contrast to both TD groups, children with ASD generated location-based predictions, suggesting that their visual predictions may reflect visuomotor perseveration. Together, these results suggest differences in early predictive reasoning abilities. The current study examines the ability to generate visual predictions regarding other people’s goal-directed actions, specifically reaching and grasping an object, in infants and children with and without autism spectrum disorder. Results showed no differences in abilities when movement information about a person’s goal was evident; however, differences were evident across age and clinical diagnoses when relying on previous knowledge to generate a visual prediction.
