Children with autism spectrum disorder (ASD) often encounter difficulties in language learning and utilization, a concern that has gained significant academic attention, particularly given the widespread occurrence of ASD globally. Previous reviews, however, have relied on empirical observations rather than a more rigorous selection criterion. This preliminary study seeks to systematize the scientific knowledge base regarding language development in autistic children by utilizing the analysis tool Citespace 6.2.R5. We visualized and analyzed research patterns and trends regarding autism by drawing data from the Web of Science. Through document citation and emerging trend analyses, seven key research clusters and their chronological associations are identified, along with research hotspots such as language disorder diagnosis and intervention, social communication, language acquisition, and multilingual and multicultural influences. Research findings show that there exist some issues with the current research, including small sample sizes, the need for further investigation into receptive language development, and a lack of cross-cultural comparative studies. Meanwhile, the scope and depth of interdisciplinary research on language development in autistic children also need to be further enhanced. The research contributes to the extant literature by providing valuable references for autism researchers and practitioners.
