The mathematical abilities of children with autism spectrum condition have been understudied. Magnitude representation is a fundamental numerical ability that emerges early in development and is linked to children’s learning of formal mathematics. It remains unclear about whether children with autism spectrum condition differ from their peers without autism spectrum condition in the precision of magnitude representations. This study recruited preschool-aged children with autism spectrum condition ( N = 70; 64 boys, Mage = 5.20 years) and without autism spectrum condition ( N = 117; 63 boys, Mage = 5.11 years), and tested their precision of magnitude representation with an approximate number comparison task (dot comparison). Children with autism spectrum condition exhibited the lower numerical comparison accuracy (i.e. the weaker magnitude representation) than their peers without autism spectrum condition, regardless of the congruency between numerosity and surface area of dots. Moreover, the lower numerical comparison accuracy was observed even controlling for multiple general cognitive abilities (working memory, inhibitory control, and nonverbal intelligence) and language abilities. In addition, the variability of the comparison accuracy was larger in children with autism spectrum condition than without autism spectrum condition. These findings suggest that children with autism spectrum condition are at risk of weaker magnitude representation from an early age, emphasizing the need for specialized mathematics education or interventions to support their learning. Lay abstract The mathematical abilities of children with autism spectrum condition have been understudied. Magnitude representation (e.g. presenting the number of a collection of objects) is a fundamental numerical ability presented since early infancy and is correlated with children’s later learning of formal mathematics. It remains unclear about whether children with autism spectrum condition differ from their peers without autism spectrum condition in precision of magnitude representations. This study compared preschool children with and without autism spectrum condition in their precision of magnitude representation with an approximate number comparison task, in which children compared two sets of dots without counting and chose the set with more dots. Children with autism spectrum condition exhibited the lower numerical comparison accuracy (i.e. the weaker magnitude representation) than their peers without autism spectrum condition. This difference existed even when multiple general cognitive abilities (working memory, inhibitory control, and nonverbal intelligence) and language abilities were statistically controlled. Moreover, the individual difference of the numerical comparison accuracy was larger in children with autism spectrum condition than without autism spectrum condition. These findings suggest that children with autism spectrum condition are at risk of weaker magnitude representation from an early age, emphasizing the need for specialized mathematics education or interventions to support their learning. In addition, the large variance in the precision of their magnitude representation suggests that individualized mathematics interventions are needed for children with autism spectrum condition.

The purpose of the current study was to investigate the contribution of different cognitive processes to specific math abilities in students with autism spectrum disorder (ASD) and typically developing (TD) students. The study involved a group of students with ASD without intellectual disabilities (n = 26) and a group with TD students (n = 52). The two groups aged from six to 20 years old and were matched for age, sex ratio and visuospatial reasoning. To assess math abilities, four math tasks were administered: arithmetic facts, mental calculation, mathematical inferences and math problem solving. Concerning cognitive processes, participants were tested on vocabulary, verbal working memory, visuospatial working memory, response inhibition and interference control. The group with ASD showed lower scores on all specific math measures than the TD group; cognitive processes differently contributed to diverse math abilities, and vocabulary and verbal working memory were stronger associated to specific math abilities in the group with ASD than in the TD group. The current results suggest that students with ASD had lower math abilities that are generalized to different math tasks. Implications for research and clinical assessment and intervention were discussed.
Bu çalışmanın amacı, otizm spektrum bozukluğu (OSB) tanısı olan okul öncesi dönemdeki çocukların erken çocukluk dönemindeki sayı becerilerini sayı hissi bağlamında incelemektir. Erken çocukluk döneminde gelişmeye başlayan sayısal beceriler, gelecekteki matematiksel beceriler için temel niteliğindedir. Bu nedenle OSB'li çocuklarda sayı becerilerinin gelişimi etkili müdahalelerin uygulanması açısından önemlidir. Bu araştırmada deneysel olmayan betimsel desen kullanılmıştır. Katılımcılar Doğu Anadolu Bölgesi’ndeki bir ilin özel eğitim uygulama anaokulunda eğitimine devam eden okul öncesi dönemdeki OSB’li çocuklardan oluşmaktadır. Okul öncesi dönemdeki OSB’li çocukların sahip oldukları sayı becerilerinin tespiti için TEMA-3 (Test of Early Mathematics Ability-Third Edition) kullanılmıştır. Çocukların testteki sorulara verdikleri yanıtlara göre TEMA-3 ‘ün değerlendirme esaslarında kullanılan ham puan, yaş denkliği, düzey denkliği, yüzde, matematik yetenek puanı hesaplanmıştır. Bu değerlendirme sürecinde nicel betimsel analiz kullanılmıştır. Bulgular, katılımcıların sayısal becerilere farklı düzeylerde sahip olduğunu ve her birinin güçlü ve zayıf yönlerinin olduğunu ortaya koymaktadır. Özellikle ağır düzeyde OSB tanısına sahip olan katılımcının performansının çok düşük olduğu görülmüştür. Okul öncesi dönemdeki OSB’li çocukların sayısal becerilerini geliştirmek için erken müdahale programları, somut materyaller ve bireyselleştirilmiş öğretim faydalı olabilir. Ayrıca ailelerin katılımı ve iş birliği de önemlidir. Bu çalışmanın bulguları, toplumsal farkındalığı artırarak eğitimde kapsayıcı yaklaşımları desteklemeye yönelik önemli bir katkı sağlamaktadır. Önerilen stratejiler, OSB'li çocukların matematik potansiyellerini ortaya çıkarmayı ve başarılarını artırmayı hedeflemektedir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
