Hyperlexia 1st appeared in the literature in a 1967 paper describing youthful small children with reading abilities exceeding their language comprehension competencies (Silberberg & Silberberg, 1967). The first sights of hyperlexia proposed that phrase recognition skills had been individual from a child’s verbal performing.
Though hyperlexia is not a diagnostic expression, it can be used to describe kids with abnormal examining behaviors. The dilemma arises in defining the threshold among typical reading development and hyperlexia. Scientists disagree on definitions of hyperlexia, these kinds of as debating how a great deal far more highly developed the examining skill desires to be in comparison to peers and irrespective of whether the highly developed looking through requires to be paired with developmental disabilities (Zhang & Joshi, 2019). The lack of consensus on a definition tends to make studying hyperlexia tricky for psychological, academic, and developmental researchers.
Hyperlexia can be considered of as the inverse of another examining dysfunction referred to as dyslexia. Examining comprehension is recognized to be a complicated exercise demanding both of those ample decoding expertise and listening comprehension. A child’s decoding expertise and listening comprehension function jointly to assistance their reading through comprehension. This is recognized as the very simple look at of looking through (Hoover & Gough, 1990). The very simple look at of looking at is comprehended most effective by the equation: Decoding x Listening Comprehension = Looking through Comprehension.
Little ones with hyperlexia have superb decoding techniques and very poor listening comprehension ensuing in very low reading comprehension. Youngsters with dyslexia have bad decoding capabilities with normal to previously mentioned common listening comprehension, and their profile also success in very low reading comprehension. Investigation studies as a complete help the hyperlexic profile as a child with superior decoding ability and very poor listening and examining comprehension (Zhang & Joshi, 2019). Kids with hyperlexia consequently have impaired reading through comprehension, a style of unique learning problem that added benefits from intervention and accommodation.
Hyperlexic profiles can be divided into three principal styles (Treffert, 2011):
Hyperlexia I: Neurotypical young children who are very best explained as precocious visitors. Lots of of these young children might have early obtain to studying components. Some researchers argue that precocious reading really should not be deemed hyperlexia (Ostrolenk et al., 2017), and most concur that there is no intervention necessary for neurotypical little ones with advanced reading capabilities.
Hyperlexia II: Hyperlexia II is linked with autism spectrum dysfunction. Several autistic persons have erratically made cognitive profile, and some have what is referred to as a splinter skill (Treffert, 2014): a skill or interest that is unusually significant when compared to a person’s other expertise. It has been approximated that involving 6%-20% of autistic little ones also have hyperlexia (Ostrolenk et al., 2017).
Hyperlexia III: These kids have hyperlexia paired with some features of autism, nevertheless their social communication profile could not align with the diagnostic standards for autism. They might be sensitive to sensory information, echo language, and struggle with alterations in regime. Nonetheless, they also show regular or close to-typical social communication skills. Typically, these autistic-like attributes fade with age.
A regular evaluation of hyperlexia will commonly get started with a broad intelligence or developmental evaluate. Language tests, either carried out by a speech pathologist or a psychologist, is also very important. Term studying and examining comprehension are also assessed. Lastly, simply because of the strong overlap involving hyperlexia and autism, autism-unique analysis instruments need to be administered. These can include things like a complete developmental heritage, immediate tests, document critique, father or mother surveys, and inventories of autistic traits. Regular intervention recommendations incorporate speech/language therapy.
