Abstract / Summary: 

Purpose: Even though the concept of dyslexia – individuals with poor decoding skills but good comprehension skills is fairly well established, the other reading problem, hyperlexia – individuals with good decoding skills but poor comprehension skills is not well understood. Some researchers (i.e., Grigorenko, 2002; Wing, 1981) consider hyperlexia as occurring only among clinical cases, while others (i.e., Healy, 1986; Silberberg & Silberberg, 1971) have considered hyperlexia as having a discrepancy between decoding and comprehension. The purpose of this presentation is to examine systematically various definitions and classifications of hyperlexia in the literature.
Method: Articles published in high-impact journals on hyperlexia were perused based on their definitions and classifications.
Results: Based on this systematic review, the concept of hyperlexia is not well defined in the literature due to the definitional issues. The authors of this presentation bridged definitions of hyperlexia to propose a framework by combining different features and their variable prevalence.
Conclusions: In order for clinicians and educators to help individuals with hyperlexia, a standard definition is needed. Aspects relating to autism spectrum disorder is one of the important criteria that should be considered for classification. It concludes understanding hyperlexia helps educators provide hyperlexic children with educational interventions so they can improve their reading abilities. There are other features of hyperlexia (i.e., common features with autism spectrum disorders) which vary in their prevalence that need to be taken into account to diagnose hyperlexia accurately.
