Information Processing in Sport

Why Performers Need to Process Information

Every movement in sport begins with the brain receiving information from the environment and deciding how to respond. A netball player catching a pass, a goalkeeper preparing for a penalty, a sprinter reacting to the gun — all of them are processing information before they act. Sports psychologists use the information processing model to describe this sequence. Understanding the model helps coaches identify where a performer is breaking down — are they missing key cues (input problem), making wrong choices (decision making problem), or executing the wrong movement (output problem)?

Stage 1 — Input

The input stage is where the performer gathers information from the display — everything around them that could be relevant. The senses provide raw data: eyes track the position of the ball and defenders, ears pick up shouts from teammates, proprioceptors in muscles and joints provide information about body position and balance. However, the display contains far more information than the brain can fully process at once. This is where selective attention becomes critical. Selective attention is the performer’s ability to focus on relevant stimuli and filter out distractions. An experienced midfielder reading the game attends to teammates’ runs and opponents’ positions while ignoring crowd noise and irrelevant movement. A novice player, overwhelmed by the display, struggles to attend selectively — they look at the ball rather than scanning the field, or freeze under pressure because too many stimuli compete for attention. Coaching and practice improve selective attention by teaching performers which cues are significant.

Stage 2 — Decision Making

Once relevant information has been attended to, the performer must decide what to do. Decision making draws on two types of memory. Short-term memory (also called working memory) holds the immediate situation: the current positions of players, the recent pattern of play, the score. It has a limited capacity — typically around seven items — and information fades quickly if not rehearsed. Expert performers use short-term memory efficiently, chunking complex patterns into single meaningful units (“their right winger always cuts inside on the overlap”). Long-term memory, by contrast, is vast and essentially permanent. It stores all the movement patterns, tactics and sport knowledge the performer has ever learned. When a basketball player recognises a defensive formation they have practised against hundreds of times, they retrieve the appropriate offensive response directly from long-term memory — faster than conscious deliberation would allow. This is why experienced players appear to have “more time” on the ball: their long-term memory does the anticipatory work that novices must do consciously and slowly.

Stage 3 — Output

Once a decision is made, the brain transmits output to the muscles via the motor system. The selected movement pattern — retrieved from long-term memory as a motor programme — is sent to the relevant muscle groups to execute the response. For a highly practised skill, this output is rapid and automatic: Adam Peaty’s breaststroke leg kick happens without conscious muscular instruction. For a beginner attempting the same movement, each element must be consciously directed, slowing output considerably. The quality of output depends on both the accuracy of the decision and the technical competence of the performer: even a correct decision can result in poor output if the physical skill is not yet well-learned.

Stage 4 — Feedback

After the movement, the performer receives feedback that feeds back into the input stage, completing the cycle. Feedback can come from internal or external sources. Intrinsic feedback comes from within the performer — the proprioceptive “feel” of a well-struck golf ball, the kinaesthetic sense that a landing was balanced, the physical sensation of muscle fatigue. It is available immediately and continuously during performance. Extrinsic feedback comes from outside — a coach shouting “head up when you pass”, seeing the ball hit the target, reading a score or split time. Extrinsic feedback is particularly important for beginners, who have not yet developed the proprioceptive sensitivity to rely on intrinsic feedback alone. Feedback can also be categorised as knowledge of results (what happened — the ball went in the net) or knowledge of performance (how it was done — the angle of the foot at contact was correct). Knowledge of performance is generally more useful for skill development because it tells the performer specifically what to adjust.
