Development of Coincidence-Anticipation Timing in a Catching Task

Abstract

This study examined the effects of age, target location, and stimulus speed on coincidence-anticipation timing in a catching task. Males aged 11 to 18 years made simulated catching movements toward a light stimulus that rapidly approached the head or chest at various speeds. Coincidence-anticipation timing accuracy, movement onset times, and movement times did not differ by age. However, 17- to 18-year-olds exhibited significantly faster movement speeds than 14- to 16-year-olds. Target location (head or chest) did not affect coincidence-anticipation timing accuracy or movement speed. However, movements toward the head were initiated earlier and took longer than movements to the chest. Finally, stimulus speed had statistically significant effects on all measures: faster stimuli were associated with longer delays in coincidence-anticipation timing responses, earlier movement onset times, shorter movement times, and faster movement speeds. These results underscore the adaptability of coincidence-anticipation timing abilities for responding to stimuli under varying temporal and spatial constraints.
