Auditory and Visual Working Memory Functioning in College Students with Attention-Deficit/Hyperactivity Disorder...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Educational Psychology

Background:

• Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are common neurodevelopmental disorders affecting academic performance.
• Working memory (WM), crucial for learning, is often impaired in these populations.
• Understanding domain-specific WM deficits (auditory vs. visual) is vital for targeted interventions.

Purpose of the Study:

• To compare auditory and visual working memory (WM) in college students with ADHD, LD, and clinical controls.
• To investigate the influence of ADHD subtype on WM functioning.
• To examine the relationship between WM domains and academic abilities (reading, math).

Main Methods:

• A sample of 268 postsecondary students was divided into four groups: ADHD only, LD only, comorbid ADHD and LD, and clinical controls.
• Participants received comprehensive neuropsychological evaluations.
• Diagnoses were confirmed using a multi-informant, multi-method approach by licensed psychologists.

Main Results:

• No significant difference in auditory versus visual working memory was found in the ADHD-only group.
• Individuals with LD exhibited significantly weaker auditory working memory compared to visual working memory.
• ADHD subtype (inattentive vs. combined) did not influence auditory or visual working memory performance.
• Visual working memory did not significantly predict academic achievement.

Conclusions:

• Individuals with ADHD did not show significant working memory deficits compared to clinical controls.
• Learning disabilities were associated with poorer auditory working memory functioning.
• Auditory working memory deficits may be a key characteristic differentiating LD from ADHD in academic contexts.
