Understanding the Phonological Core Deficit
Research shows that dyslexia is fundamentally linked to a phonological core deficit, which is a subtle difference in the brain’s processing of speech sounds. This deficit makes it challenging for individuals with dyslexia to recognize and manipulate discrete speech sounds, which are artificially divided in written language. For example, when a word like ‘bill’ is spoken, it is not naturally segmented into individual sounds; instead, it flows as a continuous sound. This artificial division, necessary for written language, poses a significant challenge for those with dyslexia.

Educators often find that understanding the phonological core deficit is crucial for developing effective teaching strategies. By acknowledging that words are not naturally segmented in speech, educators can better support students in learning to recognize and manipulate these artificial divisions. This understanding can lead to more targeted interventions that focus on building phonological awareness, a key component in reading development.
