Short-term memory tasks interfere with motor planning
Short-term and working memory tasks interfere with motor planning and performance, as demonstrated by cognitive-motor dual-task paradigms.
The claim is specific, empirical, and falsifiable. Papers 0, 1, and 6 provide direct and supportive evidence demonstrating that working memory and executive tasks create cognitive-motor interference, disrupting motor performance, planning, and timing. No papers refute the claim.

Paper 0 establishes that early executive and working memory alterations in neurodegenerative conditions correlate directly with broader planning and motor deficits.

Paper 1 directly demonstrates cognitive-motor interference, showing that working memory load disrupts motor performance parameters like reaction times and grip forces during dexterous object manipulation.

Paper 6 confirms through a systematic review and meta-analysis that concurrent cognitive loads such as memory assessments amplify motor performance differences and disrupt motor timing.
