Attentional narrowing is the reduction in the range of cues an individual notices and processes. It happens as arousal increases, particularly in high-pressure, stressful, threatening, or fast-moving sporting situations.
How attentional narrowing works
Attention has a limited capacity. According to cue utilization theory, low arousal allows an athlete to attend to a broad range of relevant and irrelevant cues. As arousal rises, the athlete's attentional field becomes narrower, so fewer cues are processed.
Moderate narrowing can improve performance by filtering out distractions and directing attention toward the most relevant information. For example, a basketball player taking a free throw may ignore crowd noise and concentrate on the rim and shooting technique.
However, excessive arousal can narrow attention too far. The athlete may experience perceptual narrowing, sometimes called tunnel vision, and fail to notice important peripheral cues. For example, an anxious football player may focus only on the defender directly ahead and miss an unmarked teammate to the side.
| Arousal level | Attentional effect | Likely performance consequence |
|---|---|---|
| Low | Attention is broad and may include irrelevant cues | Distraction or lack of focus |
| Moderate | Irrelevant cues are excluded while relevant cues remain available | Improved concentration and decision-making |
| Excessively high | Attention becomes too narrow | Relevant peripheral cues are missed and decisions may deteriorate |
A common misconception is that attentional narrowing is always harmful. In fact, some narrowing is beneficial when it removes irrelevant information; it becomes harmful when relevant cues are also excluded. The ideal attentional width depends on the task: an archer benefits from a narrow focus, whereas a games player must monitor several changing cues.
Exam technique
For an IB SEHS response on C.2.2 Attentional control, define attentional narrowing, link it explicitly to increasing arousal, and apply it to a sporting example. For an explain question, show the full causal chain: increased arousal leads to reduced cue utilization, which can exclude relevant peripheral information and impair performance.
