CORE DIMENSIONS OF DYSLEXIA

  • Origin
  • Attributes
  • Instructional Factors

Miciak and Fletcher (2020) identified shared dimensions derived from common definitions of dyslexia including:

Origin: Dyslexia is a brain-based disorder that is frequently associated with difficulties in phonological processing, cognitive processing, or both.

Attributes: Dyslexia is characterized by difficulties in foundational skills that involve the ability to read and spell words accurately and fluently. It also involves unexpected difficulties in reading in relation to other cognitive abilities.

Instructional Factors: Dyslexia and the reading difficulties associated with it are not the result of lack of access or exposure to phonics instruction.
