When attention is intact in adults with ADHD.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Clinical Psychology

Background:

• Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention and hyperactivity.
• Previous research on visuospatial attention in adults with ADHD has yielded inconclusive results.
• Methodological inconsistencies and varied terminology have hindered a clear understanding of attention deficits in ADHD.

Purpose of the Study:

• To investigate whether covert visuospatial attention is preserved in adults with ADHD.
• To compare the effects of voluntary and involuntary attention on perceptual performance in adults with ADHD and neurotypical controls.
• To clarify the functional status of spatial covert attention in adult ADHD.

Main Methods:

• Utilized well-established spatial cueing protocols.
• Assessed an orientation discrimination task.
• Compared adults with ADHD to age- and gender-matched neurotypical controls.

Main Results:

• Voluntary attention improved accuracy and reduced reaction times at relevant locations for both groups.
• Voluntary attention impaired accuracy and slowed reaction times at irrelevant locations for both groups.
• Involuntary attention similarly enhanced accuracy and speeded responses in both groups.
• Crucially, the magnitude of all orienting and reorienting attention effects was indistinguishable between adults with ADHD and controls.

Conclusions:

• Spatial covert attention is functionally intact in adults with ADHD.
• The findings suggest that core mechanisms of spatial attention are not impaired in adult ADHD.
• These results challenge previous assumptions about attention deficits in ADHD and highlight the need for refined research methodologies.
