This study was designed to investigate separately the inhibitory response capacity and the lateralization effect in children with developmental coordination disorder (DCD) in the endogenous and exogenous modes of orienting attention. Children with DCD on the lower extremities (DCD-LEs), along with age-matched controls, completed four tasks that involved various applications of asynchronous stimuli to the feet or hands at various intervals. The results demonstrated that children with DCD-LEs had a significantly longer reaction time than the controls for all tasks, and were not alert to the appearance of the target. However, they displayed a deficit in volitional shifts of attention (endogenous mode), but not in automatic dislocation of attention (exogenous mode), whenever they performed the tasks with either their lower or their upper-limbs--even 6 months after the initial study. These findings confirm the deficit in the inhibitory response capacity in terms of volitional movement of attention by children with DCD. Additionally, the negative effect of lateralization on the bilateral extremities was not present in children with DCD-LEs. Significantly differences in response ability were detected only between the dominant and non-dominant sides of upper-limbs, but not between the lower-limbs, suggesting a future avenue for further experimentation on bilateral extremities.
