Use a brief distraction task immediately before execution

Give working memory something else to do so it can’t hijack your automated skill.

Why it works

Beilock’s research demonstrated an ironic effect: expert performers who verbalized their putting mechanics during execution performed significantly worse than those given an irrelevant secondary task (detecting a tone). The secondary task occupied the working-memory capacity that would otherwise be used for explicit monitoring, allowing the procedural motor system to execute without interference. A brief, absorbing distractor just before execution achieves the same effect.

How to do it

1. Identify a brief cognitive task that reliably absorbs working memory without touching your performance domain: count backwards by threes, repeat a word or phrase, focus on breathing rhythm.
2. Apply it during the last few seconds before execution — the window when self-monitoring is most likely to begin.
3. Keep it brief and consistent so it becomes part of the pre-performance routine rather than an improvised tactic.
4. Test it in practice at high-effort moments so you know it works for you before you need it under real pressure.

Evidence

Beilock’s dual-task paradigm research shows that a concurrent secondary task during execution prevents expert choking by occupying working-memory resources that would otherwise engage explicit monitoring. This is one of the strongest experimental demonstrations of the choking mechanism. Beilock, Carr, MacMahon and Starkes (2002) reinforce the direction of the effect: for experienced performers a divided-attention (secondary) task left execution intact while skill-focused attention degraded it.

The dual-task effect was demonstrated in laboratory tasks (golf putting, soccer dribbling); real-world distraction tasks must be chosen carefully to avoid genuinely interfering with performance-relevant attention.

Common mistake

Choosing a distractor that is in the same domain as the performance (thinking about a different aspect of the skill), which just redirects monitoring rather than freeing the automated system.
