Children with autistic spectrum disorder and controls performed tasks of coherent motion and form detection, and motor control. Additionally, the ratio of the 2nd and 4th digits of these children, which is thought to be an indicator of foetal testosterone, was measured. Children in the experimental group were impaired at tasks of motor control, and had lower 2D:4D than controls. There were no group differences in motion or form detection. However a sub-group of children with autism were selectively impaired at motion detection. There were significant relationships between motion coherence detection and motor control in both groups of children, and also between motion detection, fine motor control and 2D:4D in the group of children with autistic spectrum disorder.
患有自闭症谱系障碍的儿童和对照组儿童进行了连贯运动、形状检测及运动控制任务。此外，还测量了这些儿童的食指与无名指长度比，该比例被认为是胎儿睾酮水平的一个指标。实验组儿童在运动控制任务方面存在缺陷，且其二指与四指长度比低于对照组。在运动或形状检测方面两组无差异。然而，有一个自闭症儿童亚组在运动检测方面存在选择性缺陷。两组儿童的运动连贯性检测与运动控制之间均存在显著关系，并且在自闭症谱系障碍儿童组中，运动检测、精细运动控制与二指与四指长度比之间也存在显著关系。
