A longitudinal study on language acquisition in monozygotic twins concordant for autism and hyperlexia
Background
Hyperlexia, a strong orientation towards written materials, along with a discrepancy between the precocious acquisition of decoding skills and weaker comprehension abilities, characterizes up to 20% of autistic children. Sometimes perceived as an obstacle to oral language acquisition, hyperlexia may alternatively be the first step in a non-social pathway of language acquisition in autism.
Method
We describe two monozygotic twin brothers, both autistic and hyperlexic, from the ages of 4 to 8 years old. Following an in-depth diagnostic assessment, we investigated cross-sectionally and longitudinally their verbal and non-verbal cognitive abilities, language, reading and writing skills, interests, and strengths.
Results
The twins’ features, including their high non-verbal level of intelligence, their special interests, and their skills in various domains, were highly similar. Their language consisted exclusively of letters and numbers until their fourth year. After that, their vocabulary broadened until they developed full sentences, and their perception-related interests expanded and merged over time to serve the development of other skills.
Conclusion
Our results show that hyperlexic skills can be harnessed to favor oral language development. Given the strong concordance between the twins’ cognitive and behavioral phenotypes, we discuss the environmental and genetic influence that could explain their abilities.
期刊介绍：
Brain and Cognition is a forum for the integration of the neurosciences and cognitive sciences. B&C publishes peer-reviewed research articles, theoretical papers, case histories that address important theoretical issues, and historical articles into the interaction between cognitive function and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in cognition. Coverage includes, but is not limited to memory, learning, emotion, perception, movement, music or praxis in relationship to brain structure or function. Published articles will typically address issues relating some aspect of cognitive function to its neurological substrates with clear theoretical import, formulating new hypotheses or refuting previously established hypotheses. Clinical papers are welcome if they raise issues of theoretical importance or concern and shed light on the interaction between brain function and cognitive function. We welcome review articles that clearly contribute a new perspective or integration, beyond summarizing the literature in the field; authors of review articles should make explicit where the contribution lies. We also welcome proposals for special issues on aspects of the relation between cognition and the structure and function of the nervous system. Such proposals can be made directly to the Editor-in-Chief from individuals interested in being guest editors for such collections.
