This longitudinal study investigated parents' different pretend play behaviors (substitution, animation, and role enactment) to their infants during free play and the bidirectional links with infants' vocabulary development at 14 months (Time-1: N = 34, M[subscript age] = 14.23 months) and 20 months (Time-2: N = 34, M[subscript age] = 20.33…

Prediction from early development to later achievement has the potential to improve clinical and educational service delivery as well as to inform developmental theory. In this longitudinal study, we asked how well can educational achievement measured in the final year (Grade 9, age 15) of compulsory education--both overall and for outcomes in the…

The role of working memory (WM) in language acquisition has been widely reported in the developmental literature, but few studies have explored the role of sentence recall in the way WM and related linguistic abilities evolve. This study seeks to explore the organization and development of the memory architecture underlying language using a…

Infants have remarkable abilities to learn several languages. However, phonological acquisition in bilingual infants appears to vary depending on the phonetic similarities or differences of their two native languages. Many studies suggest that learning contrasts with different realizations in the two languages (e.g., the /p/, /t/, /k/ stops have…

Translation equivalents (TEs) characterize the lexicon of bilinguals from the early stages of acquisition, as reported in studies involving English and other languages in which most cross-language synonyms are dissimilar in phonological form. This research explores the emergence of TEs in Spanish-Catalan bilinguals who are acquiring two languages…

Growth modeling was applied to monolingual (N = 26) and bilingual (N = 28) word learning from 14 to 36 months. Level and growth rate of vocabulary were lower for Finnish-Russian bilinguals than for Finnish monolinguals. Processing of Finnish speech sounds at 7 but not at 11 months predicted level, but not growth rate of vocabulary in both Finnish…

The present study investigated the associations of Korean mothers' attention regulation and referential speech during play with their toddlers' language and play development. The play interaction between mothers (n = 42) and their toddlers aged between 13 and 23 months was videotaped during home visits. Maternal behavior in regulating their…

Caregivers of 608 (331 boys and 277 girls) children in Shanghai, China reported on their children's language development and on the language teaching practices used in the home. The children were between 24 and 47 months old. The relation of age-corrected language level to paternal education, child gender, and teaching practice use was examined.…

Reconsiders the predominant views on the acquisition of kinship terms. Topics discussed include: (1) kinship and the ontogenesis of logic; (2) kinship and semantic development; (3) the language learner as naive theorist; (4) development and domain specificity; and (5) an alternative approach to kinship.
