ABSTRACT
People commonly use pre-cue information to advance and reduce the information processing time required for a motor task (e.g., motor planning). However, children with developmental coordination disorder (DCD) exhibit difficulties performing pre-cued goal-directed tasks. The purpose of the present study was to investigate the use of valid, neutral, and invalid pre-cue information for a goal-directed task. The participants were 11 children with DCD (mean age = 7.94 yrs.) and 11 typically developed (TD) age- and gender-matched children. The children with DCD exhibited delayed motor planning (e.g., reaction time) under the invalid condition compared to that of the TD children. The children with DCD used atypical strategies for motor execution and depended more on online corrections (e.g., increased deceleration time and movement units) to reach the target. These results suggest that children with DCD have difficulties handling unpredictable situations and that the use of atypical motor execution strategies did not affect movement time
