Social interaction relies heavily on interpreting dynamic visual information to guide motor behavior []. In sighted individuals, dynamic visual cues from the eyes, mouth, limbs, and face support key social‐motor functions such as joint attention, language acquisition, gesture imitation, and emotion recognition []. Children with autism spectrum disorder (ASD), however, show particular difficulty using dynamic visual input for motor control—a process referred to as dynamic visual‐motor integration (VMI) [, , , , , ]. Dynamic VMI difficulties are evident in both goal‐directed motor tasks (e.g., intercepting a moving ball) [, , ] and social contexts (e.g., synchronizing movements with others during imitation) []. Several theoretical accounts have been proposed to explain these dynamic VMI impairments. One view highlights broader autism‐associated difficulties processing fast‐changing sensory input, which may lead to fragmented perception of dynamic stimuli []. A more specific interpretation suggests that the core issue lies in difficulties with dynamic VMI in autism, which disrupt the development of motor and social skills through observational learning and imitation [, ]. To test the hypothesis that individuals with ASD show particular difficulty with dynamic VMI as stimulus speed increases, one can examine changes in tracking performance across different speed levels. In a study by Lidstone and colleagues, a comparison of grip‐force tracking accuracy between static and dynamic conditions revealed that children with ASD showed particular difficulties in a dynamic, but not static, condition, when compared with typically developing (TD) children []; further, in contrast to ASD, children with attention‐deficit/hyperactivity disorder (ADHD) and fetal alcohol spectrum disorder (FASD) did not show static versus dynamic performance differences when compared with TD children []. These findings suggest that neurodevelopmental difficulties with dynamic VMI may be particular to children with ASD.
