Abstract: A latest examine highlights that many autistic youngsters present an intense curiosity in letters and numbers, which can play a definite position of their language improvement. By analyzing scientific data and interviewing mother and father, researchers discovered that 37% of autistic youngsters had a powerful curiosity in letters, in distinction to simply 3% of non-autistic friends.
This curiosity usually emerges round 30 months, aligning with typical improvement timelines however diverging in the way it’s utilized. Autistic youngsters are likely to discover letters and numbers independently, probably contributing to distinctive language-learning paths.
The findings recommend that encouraging this curiosity might help language acquisition for some autistic youngsters, difficult the notion that such pursuits impede social improvement. Researchers hope these insights encourage instructional variations that higher accommodate neurodiverse studying pathways.
Key Info

Throughout diagnostic assessments, many autistic youngsters spontaneously head to the magnetic board with letters and numbers. How widespread is that this curiosity in letters and numbers amongst autistic youngsters? What exactly is the character of this curiosity? And what does it imply for his or her language improvement?
Canadian autism researcher Alexia Ostrolenk – who earned her PhD in psychiatric sciences at Université de Montréal beneath the supervision of professor Laurent Mottron, a psychiatrist on the Rivière-des-Prairies Psychological Health Hospital of the CIUSSS du Nord-de-l’Île-de-Montréal – got down to reply these questions.
In a large-scale examine, Ostrolenk and her analysis staff of doctoral college students at UdeM and Université de Sherbrooke examined the medical data of 701 younger youngsters assessed for autism spectrum dysfunction on the UdeM-affiliated Rivière-des-Prairies Psychological Health Hospital clinic between 2018 and 2021.
Of these 701, 391 had been identified with autism and 310 weren’t autistic. Their common age was four-and-a-half, and all have been beneath the age of seven.
“We combed by means of reviews written by psychiatrists and psychologists to see in the event that they talked about something associated to the kid’s curiosity in letters or numbers,” mentioned Ostrolenk, who’s now a postdoctoral researcher with a CIHR Health System Impression Fellowship, based mostly at Autism Alliance of Canada and Unity Health Toronto.
Whereas at UdeM, she was assisted in her analysis by PhD candidates David Gagnon (psychiatry, UdeM), Mélanie Boisvert (psychiatry and habit, UdeM), Océane Lemire (psychology, UdeM), Sophie-Catherine Dick (psychology, UdeS) and Marie-Pier Côté (psychology, UdeM).
Of their examine, the scholars carried out 45-minute phone interviews with a sub-sample of the 701 beneath assessment : 138 mother and father of autistic youngsters, 99 mother and father of non-autistic youngsters with atypical improvement, and 76 mother and father of kids with typical improvement.
The interviews explored the youngsters’s curiosity in letters and numbers in higher depth with questions akin to Does your baby sing the “ABC” tune? Does your baby like writing the letters of the alphabet? and Does your baby ask you to learn to them?
The questions have been designed to differentiate between social behaviours, akin to studying with an grownup, and non-social behaviours, akin to writing the letters of the alphabet on their very own.
Vital variations noticed
The examine – which was funded by the Fonds de Recherche du Québec – Health sector, Canada’s Remodeling Autism Care Consortium, and the Marcel and Rolande Gosselin Analysis Chair in Cognitive Neuroscience and Autism – discovered important variations in curiosity in letters and numbers between autistic and non-autistic youngsters.
Based mostly on the scientific reviews, 20 per cent of the autistic youngsters displayed an intense or unique curiosity in letters, in contrast with solely three per cent of the non-autistic youngsters.
The interviews with mother and father discovered an much more pronounced distinction: 37 per cent of the autistic youngsters confirmed an intense or unique curiosity in letters. That’s “lots, particularly contemplating that almost all of them have minimal verbal expertise,” commented Gagnon.”
The outcomes have been related for curiosity in numbers: 17 per cent of the autistic youngsters confirmed an intense or unique curiosity in numbers, in contrast with solely two per cent of the non-autistic youngsters. In different phrases, an autistic baby was 3.49 instances extra possible than a non-autistic baby of the identical age to indicate a heightened curiosity in numbers.
Ostrolenk’s examine additionally discovered that autistic youngsters’s curiosity in letters and numbers seems on the identical age as in youngsters with typical improvement, at a median of 30 months. That is sooner than in non-autistic youngsters with atypical improvement, the place it seems at about 36 months.
Curiosity usually undetected
It’s clear that oldsters don’t at all times spot their autistic baby’s curiosity in numbers and letters, largely as a result of autistic youngsters are likely to want solitary actions, so that they pursue their pursuits extra independently.
“Social behaviour is simpler for fogeys to see as a result of it includes them, as when their baby asks to be learn to,” defined Ostrolenk.
“However non-social behaviour can happen when the kid is alone and could be missed by the mother and father, who aren’t a part of it.”
Ostrolenk famous that there could be a hole between a baby’s behaviour and their mother and father’ perceptions: “I’ve had mother and father inform me their baby doesn’t communicate a phrase, solely to seek out, on additional questioning, that their baby is definitely saying numbers or reciting the alphabet.”
These findings recommend that autistic youngsters can develop early proficiency with letters even when there seems to be a big delay in verbal language expertise, the researchers say.
“A toddler who doesn’t talk—in different phrases, doesn’t use language to narrate to others—will however develop an curiosity in letters. They’re simply not going to make use of it within the relational dimension,” defined Gagnon.
This has led researchers to invest that some autistic youngsters should be buying data about language in a different way than different youngsters.
“There are anecdotal reviews of autistic youngsters who weren’t talking in any respect after which their mother and father heard them communicate full, complicated sentences in an emergency scenario,” mentioned Ostrolenk.
“For instance, despite the fact that he had by no means spoken earlier than, one baby was capable of clarify there was a hearth within the kitchen they usually all needed to go away instantly.”
Rethinking how they’re taught
If language acquisition follows a special developmental pathway in some autistic youngsters, what does this imply for society’s present instructional paradigm?
“Prior to now, an intense curiosity in letters was usually seen as an impediment to the kid’s regular improvement,” mentioned Ostrolenk.
“It was thought that we must always restrict this curiosity and concentrate on different facets of improvement. The concept was, these youngsters can’t communicate, we now have to cease studying to them.
“But when we will present that studying could be a necessary step within the improvement of oral language in these youngsters, then we must always encourage it and assist the kid comply with their very own path, despite the fact that it differs from the standard trajectory.”
Gagnon echoes this sentiment. “To innovate on this area, we will’t simply have a look at what the youngsters aren’t doing or are doing in a different way. We even have to know the place their pursuits lie and the way they handle to develop with what might be a special approach of perceiving the world.”

“Enhanced curiosity in letters and numbers in autistic youngsters” by Alexia Ostrolenk et al. Molecular Autism
Summary
Enhanced curiosity in letters and numbers in autistic youngsters
Background
An intense and precocious curiosity in written materials, along with a discrepancy between decoding and studying comprehension expertise are defining standards for hyperlexia, which is present in as much as 20% of autistic people. It could characterize the acute finish of a broader curiosity in written materials in autism.
This examine examines the magnitude and nature of the curiosity in written materials in a big inhabitants of autistic and non-autistic youngsters.
Strategies
All 701 youngsters (391 autistic, 310 non-autistic) beneath the age of seven referred to an autism evaluation clinic over a span of 4 years have been included. Ordinal logistic regressions assessed the affiliation between prognosis and the extent of curiosity in letters and numbers.
A nested pattern of oldsters of 138 autistic, 99 non-autistic scientific, and 76 sometimes growing (TD) youngsters accomplished an in depth questionnaire. Cox proportional hazards fashions analyzed the age of emergence of those pursuits. Linear regressions evaluated the affiliation between prognosis and curiosity degree.
The frequency of every behaviour displaying curiosity and competence with letters and numbers have been in contrast.
Outcomes
Within the two research, 22 to 37% of autistic youngsters had an intense or unique curiosity in letters. The percentages of getting a higher curiosity in letters was 2.78 instances larger for autistic youngsters than for non-autistic scientific youngsters of the identical age, and three.49 instances larger for the curiosity in numbers, even when 76% of autistic youngsters have been minimally or non-verbal.
The age of emergence of those pursuits didn’t differ between autistic and TD youngsters and didn’t rely on their degree of oral language. Non-autistic youngsters confirmed extra curiosity in letters inside a social context.
Limitations
The examine holds limitations inherent to the usage of a telephone questionnaire with caregivers and lacking sociodemographic info.
Conclusions
The emergence of the curiosity of autistic youngsters towards written language is contemporaneous to the second of their improvement the place they show a powerful deficit in oral language.
Along with latest demonstrations of non-social improvement of oral language in some autistic youngsters, precocious and intense curiosity in written materials means that language acquisition in autism might comply with an alternate developmental pathway.
