The Demise of the Discrepancy Definition of Dyslexia: Commentary on Snowling, Hulme, and Nation
Keywords:
Dyslexia, IQ, assessment, dyslexia, definition, discrepancy definitionAbstract
In this article, we review the proposal of Snowling, Hulme, and Nation (2020) to reinstate the discrepancy definition of dyslexia. Presenting logical reasons and empirical evidence that this definition is not valid, we suggest that there is no need to distinguish between individuals with dyslexia as identified through an IQ-achievement discrepancy framework and nondiscrepant poor readers.
