Motor-task performance correlations are typically weak, limiting single-test prediction.

The Claim

Correlations between performance on different motor tasks are often weak, which limits the predictive validity of measuring a single motor ability to predict overall motor performance.

Verified by Lenz ·

The Short Version

The research literature supports the claim. Across many studies, performance on one motor task often correlates only weakly or modestly with performance on other tasks, so a single measure usually cannot predict broad motor performance well. Some related tasks show moderate links, but not enough to overturn the overall pattern of task specificity.

Caveats

  • This is a general pattern, not a universal rule: closely related motor tasks can show stronger correlations than unrelated ones.
  • The claim concerns prediction of broad or overall motor performance; a single task may still be useful for assessing that specific skill.
  • Several listed sources are secondary or non-auditable, but the conclusion is supported without relying on them.
