Executive functions in adults with developmental dyslexia.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Developmental Psychology

Background:

• Executive functioning (EF) deficits are recognized in developmental dyslexia, but research often overlooks adult experiences and subjective self-perceptions.
• Current theoretical frameworks for EF are not always applied to dyslexia studies.

Purpose of the Study:

• To investigate executive functioning in adults with dyslexia using both self-report measures and objective laboratory tasks.
• To examine subjective experiences of EF difficulties in adults with dyslexia.
• To align EF assessment with current theoretical models, specifically Miyake et al.'s (2000) framework.

Main Methods:

• Administered the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) for self-reported EF.
• Conducted laboratory-based experimental tasks to assess inhibition, set shifting, and working memory.
• Compared IQ-matched groups of adults with and without dyslexia.

Main Results:

• Adults with dyslexia reported significantly more daily EF problems, especially in metacognitive areas like working memory, planning, organization, and task monitoring.
• Objective tasks revealed deficits in inhibition, set shifting, and working memory in the dyslexia group.
• EF difficulties in dyslexia extend beyond phonological processing.

Conclusions:

• Dyslexia significantly impacts the daily lives and self-perceived executive functioning of adults.
• Executive functioning deficits are evident in adulthood across multiple experimental measures.
• These findings highlight the pervasive nature of EF challenges associated with dyslexia in adults.
