Distractibility in Attention/Deficit/ Hyperactivity Disorder (ADHD): the virtual reality classroom

Area of Science:

• Cognitive Psychology
• Neurodevelopmental Disorders
• Virtual Reality Applications

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by inattention and hyperactivity.
• Standard Continuous Performance Tasks (CPT) assess attention but may not fully capture real-world distractibility.
• Virtual Reality (VR) offers immersive environments to simulate complex, distracting conditions.

Purpose of the Study:

• To evaluate the efficacy of a VR classroom CPT in differentiating children with ADHD from controls.
• To assess the impact of simulated real-world distracters on task performance in ADHD.
• To compare the diagnostic classification rate of VR CPT versus standard CPT.

Main Methods:

• Nineteen boys (8-14 years) diagnosed with ADHD and 16 age-matched controls completed a VR classroom CPT and a standard CPT.
• The VR classroom incorporated simulated auditory and visual distracters.
• Behavior Assessment System for Children (BASC) Monitor for ADHD parent ratings were collected.

Main Results:

• Children with ADHD exhibited significantly poorer performance in the VR classroom CPT compared to controls (p = .05; adjusted p = .02).
• The VR CPT achieved a higher classification rate (87.5%) than the standard CPT (68.8%).
• ADHD participants were more adversely affected by the VR classroom's distractions.

Conclusions:

• A VR classroom CPT is a promising tool for assessing distractibility in children with ADHD.
• VR environments may provide a more ecologically valid measure of attention deficits.
• The enhanced distractibility in VR highlights its potential for diagnostic and therapeutic applications in ADHD.
