In hyperlexia, a child spontaneously and precociously masters single-word reading. It can be viewed as a superability, that is, word recognition ability far above expected levels. The more common definition also includes difficulties with comprehension of printed material beyond or even at the single-word level. Many hyperlexics also have trouble understanding speech.[1] Most or perhaps all children with hyperlexia also lie on the autism spectrum.[1] Image File history File links Question_book-3. ... The autism spectrum, also called autism spectrum disorders (ASD) or autism spectrum conditions (ASC), with the word autistic sometimes replacing autism, is a spectrum of psychological conditions characterized by widespread abnormalities of social interactions and communication, as well as severely restricted interests and highly repetitive behavior. ...

Hyperlexic children are often fascinated by letters and numbers. They are extremely good at decoding language and thus often become very early readers. Some hyperlexic children learn to spell long words (such as elephant) before they are two and learn to read whole sentences before they turn three. An fMRI study of a single child showed that hyperlexia may be the neurological opposite of dyslexia.[2] Functional Magnetic Resonance Imaging (or fMRI) describes the use of MRI to measure hemodynamic signals related to neural activity in the brain or spinal cord of humans or other animals. ... This article is about developmental dyslexia. ...

Often, hyperlexic children will have a precocious ability to read but will learn to speak only by rote and heavy repetition, and may also have difficulty learning the rules of language from examples or from trial and error, which may result in social problems. It has been suggested that Rote memory be merged into this article or section. ...

Despite hyperlexic children's precocious reading ability, they may struggle to communicate. Their language may develop using echolalia, often repeating words and sentences. Often, the child has a large vocabulary and can identify many objects and pictures, but cannot put their language skills to good use. Spontaneous language is lacking and their pragmatic speech is delayed. Hyperlexic children often struggle with Who? What? Where? Why? and How? questions. Between the ages of 4 and 5 many children make great strides in communicating. Echolalia is the repetition or echoing of verbal utterances made by another person. ... This article needs to be cleaned up to conform to a higher standard of quality. ...

Social skills often lag tremendously. Hyperlexic children often have far less interest in playing with other children than do their peers.

Hyperlexia is not seen as a separate diagnosis; however, with current fMRI research revealing that hyperlexia affects the brain in a way completely opposite to that of dyslexia, a separate diagnosis may be on the horizon.
