Abstract
The aim of the study was to analyse children's performance in a coincidence/anticipation task. Three tests were administered to each child: (1) an accuracy test: a throw on a target; (2) a coincidence/anticipation test with a simple motor response: the child had to intercept an apparent movement of two different speeds by pressing a button; (3) a coincidence/anticipation test with a complex motor response implying accuracy: the child had to intercept an apparent movement with an accurate throw on target. Time errors (absolute and variable) and spatial errors were recorded. Performance, as measured by absolute and variable time errors, and spatial errors improved with age. Boys executed the coincidence/anticipation task with more temporal and spatial accuracy than girls. All subjects were more temporally precise at fast speed than at slow speed, and practice had no significant over-all effect. Complexity significantly affected absolute time error and spatial error, all children being more accurate on the task requiring a simple response.
