This study used longitudinal data to examine the acoustic differences between AMAB and AFAB children and the association between the acoustic measures and perceived gender ratings of children's speech. We found differences between AMAB and AFAB children in two acoustic parameters that mark gender in adult speech: the spectral centroid of /s/ and the overall scaling of resonant frequencies in vowels. These results demonstrate that children as young as 3 years old speak in ways that reflect their sex assigned at birth.

This study tested whether discrimination of two consecutive tones is easier when a dynamic contour tone (e.g., rising/falling) precedes a static-level tone (e.g., low/high) than vice versa. Thai-speaking children aged 4, 6, and 8 years and adults completed an AX task with four tone pairs in dynamic-static and static-dynamic orders. Adults showed no perceptual asymmetry, possibly due to ceiling effects. However, children in all three age groups discriminated dynamic-static pairs better than static-dynamic pairs. Although tone discrimination improved across age groups, the magnitude of the dynamic-static over static-dynamic advantage remained stable. These findings reveal a dynamic-static bias in tone perception that emerges before age four and remains stable into the school years. Implications for segmental asymmetries and theories of speech perception are discussed.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"30 1","pages":"1-25"},"PeriodicalIF":2.2,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148342096","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}

Using a web-based visual world eye-tracking paradigm, we tested the interpretation of pronominals (ta), simplex reflexives (ziji), and complex reflexives (taziji), which differ in their reliance on narrow syntax versus syntax-discourse-semantic integration. At the group level, taziji was interpreted locally, while ziji and ta were interpreted as referring to long-distance (LD) antecedents. Working memory and inhibition modulated the processing of ziji and ta, whereas only current heritage language (HL) exposure influenced the processing of taziji. These findings indicate that domain-general cognitive resources are recruited during the resolution of pronouns involving LD and interface-level dependencies, while narrow syntactic structures are more sensitive to variation in language exposure. The results point to structural asymmetries in how cognitive and experiential factors affect real-time HL pronoun resolution.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"72 1","pages":"1-25"},"PeriodicalIF":2.2,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148342098","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}

On the conceptual complexity explanation, children acquire if-clauses later than other morphosyntactically similar constructions because they are cognitively more complex. On the pragmatic overlap explanation, children produce if-clauses infrequently because other, simpler constructions can convey similar conditional meanings. We tested the two explanations experimentally by eliciting hypothetical language in 3- to 6-year-old children and adults. Children and adults expressed hypotheticality through a variety of grammatical constructions, beyond if-clauses, in accordance with the pragmatic overlap explanation. Across age groups, if-clauses were not delayed compared to other similar constructions, against the conceptual complexity prediction. Still, the data showed important developmental differences: 3- and 4-year-old children rarely expressed conditional meanings, whereas 5- and 6-year-olds were adult-like. These findings suggest that expressing hypothetical thought develops substantially during the preschool years through interacting cognitive, pragmatic, and linguistic factors.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"31 1","pages":"1-34"},"PeriodicalIF":2.2,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148322628","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}

Subsequently, we examined children's sensitivity to the distributional information in a few sentence types. The results demonstrated that distributional cues in these sentence types were useful for children to categorize novel verbs, since the categorization linked to verb meanings was reinforced by sentence types in which novel verbs occur.

However, the magnitude, development, and cross-cultural generality of this bias remain debated. We conducted a pre-registered meta-analysis and meta-regression of 71 studies to synthesize the evidence base. Our analysis revealed a robust overall effect, confirming the existence of a shape bias. However, this effect was characterized by extreme between-study heterogeneity (I2 = 0.95). Critically, meta-regression analyses failed to support hypothesized developmental changes, with a constant model across ages providing the most parsimonious fit. The literature is overwhelmingly dominated by studies of English-speaking children, preventing meaningful tests of cross-linguistic or cross-cultural variation. Diagnostic tests were also consistent with the possibility of publication bias, though these patterns can also arise from methodological heterogeneity and should be interpreted with caution. Together, these findings indicate that procedural variation, and potentially publication bias, more than currently testable theoretical moderators, account for the variability in the literature, severely limiting the ability to distinguish between theories of the shape bias's origins.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"20 1","pages":"1-19"},"PeriodicalIF":2.2,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148299014","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}
