Highlights

Hyperlexia is characterised by strong decoding skills and delayed comprehension.

Hyperlexia is strongly associated with autism (84% of cases are on the spectrum).

Autistic children learn to read through an inverted, non-communicative, pathway.

Hyperlexia is mediated by the extended use of the perceptual expertise system.

Favouring hyperlexia may be tested during intervention to foster communication.

Abstract

Hyperlexia is defined as the co-occurrence of advanced reading skills relative to comprehension skills or general intelligence, the early acquisition of reading skills without explicit teaching, and a strong orientation toward written material, generally in the context of a neurodevelopmental disorder. In this systematic review of cases (N=82) and group studies (including 912 participants of which 315 are hyperlexic), we address: whether the hyperlexic profile is associated with autism and why, whether models of non-autistic reading can teach us about hyperlexia, and what additional information we can get from models specific to autistic cognitive functioning. We find that hyperlexia, or a hyperlexic-like profile, characterises a substantial portion of the autistic spectrum, in which the subcomponents of the typical reading architecture are altered and dissociated. Autistic children follow a chronologically inverted path when learning to read, and make extended use of the perceptual expertise system, specifically the visual word form recognition systems. We conclude by discussing the possible use of hyperlexic skills in intervention.

FAQs

What is the conclusion of hyperlexia? ›

Conclusion: Hyperlexia, understood as meaning a little island of ability in children with autism and ASD, poses a number of questions and represents an important challenge in neuropsychological research in this population.

Are 80% of people with hyperlexia autistic? ›

Hyperlexia is characterised by strong decoding skills and delayed comprehension. Hyperlexia is strongly associated with autism (84% of cases are on the spectrum).

What part of the brain is affected in hyperlexia? ›

Hyperlexic reading is therefore associated with hyperactivation of the left superior temporal cortex, much in the same way as developmental dyslexia is associated with hypoactivation of this area.

How do you overcome hyperlexia? ›

The main treatment for Hyperlexia will be delivered by a speech and language therapist who will focus on developing and supporting communication and social interaction skills. Therapy will use the individual's advance reading and visual abilities as a tool for therapy and language learning.

Do kids grow out of hyperlexia? ›

There are three kinds of hyperlexia: Hyperlexia 1 consists of bright, neurotypical children who simply read early. Watching a child read books out loud to his or her nursery school class is always quite startling. But eventually most other children learn to read as well so that gap disappears over time.

Can you have hyperlexia and not be autistic? ›

Still, hyperlexia alone doesn't serve as an autism diagnosis. It's possible to have hyperlexia without autism. Every child is wired differently, and by paying close attention to how your child communicates, you'll be able to get them the support they need to maximize their potential.

Is hyperlexia a part of ADHD? ›

Objective: Hyperlexic-like reading (defined as word decoding much better than comprehension) has been associated with autism spectrum disorder (ASD). Here we study correlates of a hyperlexic-like reading style (HPL) in ADHD, a condition known to co-occur both with reading difficulties and ASD.

What age is hyperlexic? ›

Hyperlexia is a syndrome characterized by a child's precocious ability to read. It was initially identified by Norman E. Silberberg and Margaret C. Silberberg (1967), who defined it as the precocious ability to read words without prior training in learning to read, typically before the age of five.

Hyperlexia I is not a disorder and doesn't need a diagnosis. Hyperlexia II is diagnosed by: Ability to read far above what's expected based on a child's age. Obsession with numbers and letters.

Is hyperlexia a learning disability? ›

Hyperlexia 1: Neurotypical children without learning disabilities who start reading precociously and far above their age level. They do not show autism features.

What are the three primary characteristics evaluated for diagnosis on the autism spectrum? ›

Signs and Symptoms of ASD. People with ASD have difficulty with social communication and interaction, restricted interests, and repetitive behaviors.

What are the positives of hyperlexia? ›

Is hyperlexia a savant skill? ›

Thus, hyperlexia can be a splinter skill in savant syndrome in a child with an underlying autism spectrum disorder, but it is not necessarily so and the differentiation of autism spectrum disorder from “autistic-like” behaviors is a critical one in terms of intervention, treatment and outcome.

Are all early readers hyperlexic? ›

If your child is reading at a remarkably young age, it does not automatically mean that they are hyperlexic or that they are on the autism spectrum.

What is the incidence of hyperlexia? ›

The incidence of hyperlexia has been estimated to be 6. 6% of school-aged children with pervasive developmental disorders (Burd, Kerbeshian, and Fisher, 1985). This is the equivalent of a prevalence rate of o. 2 per 10, 000 children (Burd and Kerbeshian, 1988).

Can a savant have high IQ? ›

When the words are understood and transcend the pages to become thoughts and ideas then you are truly reading. Comprehension therefore is the capacity for understanding those thoughts and ideas. Applying what you have read and understood becomes the successful conclusion.
