Assessment of ADHD Subtypes Using Motion Tracking Recognition Based on Stroop Color-Word Tests

Area of Science:

• Neuroscience
• Developmental Psychology
• Clinical Psychology

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) presents with significant heterogeneity.
• Current ADHD subtype classification (inattentive, combined, hyperactive-impulsive) relies on subjective clinical observations.
• Objective diagnostic tools are needed to better understand ADHD subtypes.

Purpose of the Study:

• To investigate potential differences in executive function and motor control between ADHD subtypes using an objective measure.
• To explore the utility of a Microsoft Kinect-based Stroop Color-Word Test (KSWCT) for differentiating ADHD subtypes.
• To examine the influence of age on KSWCT performance in children and adolescents with ADHD.

Main Methods:

• A pilot study involving children and adolescents diagnosed with ADHD.
• Implementation of a Microsoft Kinect-based Stroop Color-Word Test (KSWCT).
• Linear mixture modeling was used to analyze performance accuracy, reaction times, and extraneous movements.

Main Results:

• Older participants demonstrated improved KSWCT performance.
• No significant differences in overall activity levels were found between ADHD subtypes (ADHD-I vs. ADHD-H/C).
• ADHD-H/C subtypes showed tendencies toward deficits in motor planning and executive control, indicated by response patterns.

Conclusions:

• Preliminary evidence suggests unique executive function characteristics may exist among ADHD subtypes.
• The study advances understanding of ADHD heterogeneity and the need for objective diagnostic tools.
• The KSWCT shows potential as a refined, objective diagnostic aid for ADHD.
