Recent research suggests that caregiver-child extratextual talk during shared book reading facilitates the development of preschool children's oral language skills. This study investigated the effects of the amount of picturebook text on mother-child extratextual talk during shared book reading. Twenty-four mother-child dyads (children aged…

This study reported the development and initial validation of the Survey of Parent/Provider Expectations and Knowledge (SPEAK), a self-administered questionnaire assessing expectations and knowledge about early childhood cognitive and language development. Development of the SPEAK was guided by the theory emphasizing the role of language input…

This study explores the developmental change of mother-child interactions in order to investigate which aspects of maternal behavior affect children's speech production. To this end, the interactions between 79 German-speaking mothers and their two- or five-year-old children were observed at two time points (12 months apart) and in two interactive…

This study aimed to investigate specific associations between structural and acoustic characteristics of infant-directed (ID) speech and word recognition. Thirty Italian-acquiring children and their mothers were tested when the children were 1;3. Children's word recognition was measured with the looking-while-listening task. Maternal ID speech was…

In her valuable commentary, Kerkhoff raises several issues, both empirical and conceptual. In particular, she argues that morphophonological regularities represented in associative memory might suffice for the acquisition of French grammatical gender. She thus questions whether a default implemented as a rule is necessary and whether it is even…

This corpus-based study demonstrates a case of bidirectional cross-linguistic influence in the acquisition of right-dislocation by Cantonese-English bilingual children and interprets the results in relation to Hulk and Müller's hypothesis for cross-linguistic influence. Longitudinal data reveal qualitative and quantitative differences between…

According to a dominant thesis, nominal endings are the privileged cues French children use to determine new nouns' gender subclass. Children will rely on phonology even in cases of discordance with natural gender. Two elicited production studies involving more than 250 4- to 17-year-olds showed that while French children did not base their gender…

The importance of input factors for bilingual children's vocabulary development was investigated. Forty-seven Argentine, 42 South Korean, 51 European American, 29 Latino immigrant, 26 Japanese immigrant, and 35 Korean immigrant mothers completed checklists of their 20-month-old children's productive vocabularies. Bilingual children's vocabulary…

Experimental studies demonstrate that contrast helps toddlers to extend the meanings of novel adjectives. This study explores whether antonym co-occurrence in spontaneous speech also has an effect on adjective use by the child. The authors studied adjective production in longitudinal speech samples from 16 children (16-36 months) acquiring eight…

The purpose of the study was to evaluate the language status of 120 young, Latino dual language learners living in poverty in the United States. Maternal language input and home language and literacy environments were examined with regard to language development at 24 and 36 months. Results suggested that even when combining English and Spanish…
