The interactive factors in focus are progressivity and balanced joint activity, which are core aspects of conversational interaction. Our analysis reveals that as children respond to Who-questions, their responses grow in length and multifunctionality. This growth is positively associated with progressivity, namely a quicker completion of the question sequence, and reduced functional load in the interlocutor's contributions, resulting in more balanced joint activity. These findings suggest that children adapt their linguistic choices by observing and aligning them with their interactive goals in conversational sequences.</p>","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":" ","pages":"575-601"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143504517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing a speaker-matched corpus of naturalistic Korean CDS and ADS, we observed that Korean CDS features shorter utterances and words, lower lexical diversity, fewer hapax legomena and interjections, a greater proportion of onomatopoeia and word play, a higher frequency of one-word utterances, and lower lexical ambiguity than ADS. Computational algorithms revealed significantly higher word segmentation F-scores for CDS than ADS, suggesting that child-oriented linguistic adaptations in CDS facilitate segmentation. This observation is further supported by statistical modelling, which indicates that the enhanced segmentability in CDS is modulated by the linguistic properties of the register. We discuss the nuanced roles of these properties in shaping the performance of segmentation algorithms.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"427 1","pages":"1-27"},"PeriodicalIF":2.2,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed age-related gains in multiple-meaning word knowledge, from ages 3 to 5. Polysemous words showed a trend of improvement from age 3, whereas homonymous word gains emerged only from age 4. The intervention program enhanced retrieval across all ages, with greater benefits for ages 4 and 5.

Verbal backchannels were analysed for quantity, type diversity, temporal distribution, and responses to opportunity points. TD children produced more verbal backchannels per minute of adult speech, especially in the middle and final conversation stages. While both groups preferred simple forms, TD children exhibited greater functional flexibility and entropy. LT children responded to fewer opportunity points, with reduced overlap and more missed chances. Despite age-appropriate standardised scores, LT children displayed persistent pragmatic deficits.

Using an elicited imitation task with 49 participants, we examine how linguistic and extralinguistic factors shape CS behaviour. The experiment manipulated matrix language (German vs. Portuguese), insertion type (adjective vs. noun), and adjective position (prenominal vs. postnominal). The results show that CS strategies vary depending on the grammatical properties of the matrix language. In German, prenominal adjective position-regardless of the language of the inserted adjective-was the strongest predictor of repetition accuracy. In Portuguese, the language of the adjective played a central role. We propose the Constraint Integration Model to account for the interaction between matrix-language properties and lexical features. Additionally, older age and more positive attitudes towards German increased the likelihood of producing switched utterances.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"46 1","pages":"1-27"},"PeriodicalIF":2.2,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that the children front more frequently, and in more contexts, than do their mothers, indicating CLI. Structural overlap increased the likelihood of fronting for only some children, whereas greater dominance in English increased the likelihood of fronting for the group.
