Purpose: This study aimed to examine the development of socializing and emotional expressions through vocalizations and jointattention (JA) behaviors in Korean-speaking children with autism spectrum disorder (ASD), compared to those with developmentaldelay (DD). Materials and Methods: Video samples were collected from 28 toddlers with ASD and 18 age-matched toddlers with DD, and vocalizationswere each coded in detail for the purpose of this retrospective research. In addition to some statistical analysis, ComputerizedLanguage Analysis was conducted to obtain the final results. Results: Although they produced a higher number of vocalizations than the DD group, the ASD group did not engage in emotionalor social interactions with their caretakers, whereas the DD group did. The children with ASD used more atypical vocalizationsand socially unengaged vocalizations than the children with DD did. JA using vocalizations in the ASD group, in particular,was largely dyadic, with triadic types occurring at a significantly lower frequency than those in the DD group. Conclusion: Results from this study indicate the importance of assessing early vocalizations in toddlers with ASD, suggesting thatsome common symptoms of ASD, such as lack of typical, emotional, and social functions in early vocalizations, could be used todevelop screening and intervention programs related to ASD.
