Overview

Experiment reveals that head movements enhance tracking accuracy in young adults, suggesting balance preservation in older individuals.

Key Points

  • To explore how postural challenges and aging influence head engagement during visuomotor tracking tasks.
  • Examined head engagement in young participants during visual pursuit tasks on firm and unstable surfaces.
  • Tracked head rotation ratio relative to the target's amplitude at different postural conditions.
  • Conducted a second experiment comparing head engagement in young and older participants with varying postural demands.
  • Head engagement increased when young participants stood rather than sat, with no differences on unstable surfaces.
  • Both tracking accuracy and postural sway increased with head engagement.
  • Older adults reduced head movements in demanding postural conditions, unlike young adults.
