Cognitive deficits and positively biased self-perceptions in children with ADHD

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Cognitive Neuroscience

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder.
• Children with ADHD often exhibit self-perception biases, particularly positive bias.
• The relationship between cognitive deficits and positive bias in ADHD requires further investigation.

Purpose of the Study:

• To examine the association between cognitive deficits and positive bias in children with and without ADHD.
• To identify specific cognitive deficits that mediate the relationship between ADHD and positive bias.
• To explore domain-specific differences (academic, social, behavioral) in this relationship.

Main Methods:

• A sample of 272 children aged 7-12 years, with and without ADHD, was assessed.
• Cognitive functions including executive processes, working memory, attention, and fluency were evaluated.
• Self-perception bias was measured across academic, social, and behavioral domains.

Main Results:

• Children with ADHD, regardless of self-perception bias, showed distinct cognitive deficits compared to controls.
• Specific cognitive deficits partially mediated the link between ADHD diagnosis and positive bias.
• Differences in cognitive deficits and positive bias varied depending on the considered domain (academic, social, behavioral).

Conclusions:

• Cognitive deficits play a role in the positive self-perception bias observed in some children with ADHD.
• These findings support the integration of cognitive interventions for managing positive bias in ADHD.
• Further research is needed to elucidate the complex interplay between cognition and self-perception in ADHD.
