自闭症儿童的生物运动知觉及偏转角度的影响研究

本研究的目的在于考察8-14岁自闭症儿童的生物运动知觉表现及偏转角度的影响。研究采用了生物运动任务范式:首先给被试观看不同偏转角度(正面、左侧45°和右侧45°)的光点动画,然后要求被试判断动画中的光点小人在做什么运动。研究结果显示,自闭症儿童与正常发展儿童在生物运动知觉表现方面存在显著性差异,自闭症儿童的生物运动知觉表现较差;在不同偏转角度任务中,正常发展儿童完成生物运动知觉的表现不存在显著性差异,但自闭症儿童存在偏转角度的优势效应,尤其在左侧45°条件下表现最好。因此,本文的结论是,8-14岁自闭症儿童的生物运动知觉能力总体水平偏低,他们的生物运动知觉表现受到偏转角度影响。

The Performance of Biological Motion Perception of Children with Autism Spectrum Disorders and the Effects of Deflection Viewpoints

Objective:To explore the biological motion perception performance of children with autism and the effects of different deflection viewpoints.Methods:Biological Motion Task was conducted.Participants saw the point-light displays with different deflection viewpoints and then judged movement behaviors in the animation.Results:The difference in the biological motion perception between autistic children and control participants was significant,and the autistic children have a worse performance.Although there was no significant difference in the biological motion perception performance of control participants under different deflection viewpoints,that difference was significant in children with autism,especially in the left 45°condition.Conclusion:Our findings suggest that the overall level of biological motion perception of children with autism was lower,and the deflection viewpoints have an effect on the biological motion perception performance of children with autism.
