Summary

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) show timing impairments in motor responses. This study found greater variability and lower accuracy in ADHD participants compared to controls.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Clinical Psychology

Background:

  • Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder impacting executive functions.
  • Precise motor timing is crucial for various daily activities and cognitive processes.

Purpose of the Study:

  • To investigate motor response timing in adolescents diagnosed with ADHD.
  • To compare timing abilities between adolescents with ADHD and neurotypical controls.

Main Methods:

  • Utilized a tapping task and an anticipation task to assess motor timing.
  • Recruited 46 adolescents with ADHD and 44 age- and sex-matched control participants.
  • Analyzed intra-individual variability and accuracy in task performance.

Main Results:

  • Adolescents with ADHD exhibited significantly higher intra-individual variability in a tapping task.
  • ADHD participants demonstrated lower accuracy on both cued and uncued anticipation tasks.
  • A correlation was found between timing variability in both tasks within both groups.

Conclusions:

  • Adolescents with ADHD experience deficits in the cognitive representation and motor production of precise motor timing.
  • These timing impairments may contribute to functional difficulties associated with ADHD.
  • Findings highlight the importance of addressing motor timing in ADHD interventions.
