How children and adults learn to intercept moving gaps

Area of Science:

• Cognitive Psychology
• Motor Learning
• Developmental Psychology

Background:

• Motor skill acquisition is crucial for daily activities.
• Understanding developmental differences in learning complex tasks is important.
• Virtual environments offer controlled settings for studying perception-action coupling.

Purpose of the Study:

• To investigate how children and adults learn to intercept moving gaps in an immersive virtual environment.
• To determine if variability of practice enhances learning in this perception-action task across different age groups.

Main Methods:

• Participants (10- and 12-year-olds, adults) biked through virtual gaps between moving blocks.
• Experiment 1: Constant speed interception. Experiment 2: Variable speed demands (speed up/slow down) followed by a novel timing.

Main Results:

• Adults improved speed control with practice. 12-year-olds showed reduced variability; 10-year-olds showed no significant learning in Experiment 1.
• In Experiment 2, adults performed well in both consistent and variable conditions. 10-year-olds benefited from variable practice on slow-down trials but not speed-up trials.

Conclusions:

• Developmental differences exist in learning to intercept moving gaps.
• Age-related changes in reliance on perceptual and memory information may influence performance in complex perception-action tasks.
