How Morning or Evening Preference Affects Hand Movement Skills at Different Times of Day in Healthy People

Abstract

Individuals with a 'neither' chronotype scored 65.12 on a manual dexterity task, significantly lower than both morning and evening chronotypes.

  • Morning chronotypes scored an average of 56.09, while evening chronotypes scored 58.94 on the same task.
  • The 'neither' chronotype performed worse in tasks requiring higher cognitive and motor demand, with significant differences noted (ps ≤ .03).
  • In tasks with lower cognitive demand, there were no significant performance differences among the chronotypes (p > .05).
  • No performance differences were observed between morning and evening chronotypes at various times of the day (ps > .05).
  • The findings suggest that the complexity of the manual dexterity task may not be significantly affected by chronotype.
