Processing visual information in elite junior soccer players: Effects of chronological age and training experience on visual perception, attention, and decision making.

Processing information in peripheral vision is an important perceptual-cognitive skill in team sports. The relative contribution of various perceptual-cognitive skills to expertise in sports throughout adolescence has not been investigated in detail yet. The current study examined the effects of chronological age and training experience on perception, attention, and decision making in young soccer players. Sixty-five elite youth players were required to judge different game situations in a decision-making task involving both perceptual (object detection) and attentional (postural feature recognition) skills to perceive player configurations in the visual periphery. In general, performance decreased in the decision-making and feature-recognition tasks with increasing use of peripheral visual field, but not in the object-detection task. Superior performances were found for under 18-years-old players compared to under 16-years-old players especially in their attentional skills. Higher training experience affected decision-making and attentional performance. Overall, the findings provide insights and implications for training perceptual-cognitive skills in team sportsHighlights Elite youth soccer players' performance decreased in a soccer-specific decision-making and feature-recognition tasks with increasing use of peripheral visual field, but not in an object-detection task.Superior performances were found for under 18 years old players compared to under 16 years old players especially in their attentional skills.Both chronological age and training experience influenced the recognition of postural feature in peripheral vision, whereas player detection was unaffected.The ability to recognize postural features in peripheral vision is an important characteristic of decision making in sports and requires a mature visual system, sufficient attentional capacity, and may be developed through extended task-specific practice.
