The study adopts a multimodal perspective, looking at adults' use of gestures in variation sets (VS; i.e. sequences of partial self-repetitions occurring in successive utterances of varying form) addressed to Spanish-learning toddlers in adult-child interactions. We seek to address the following question: Do adults make simultaneous use of VS and…

Pointing has long been considered influential in language acquisition. Certain pre-linguistic vocal expressions may hold even greater value in addressing the transition to language. The goal of the present study is longitudinal evaluation of early communicative development, addressing the influence of pre-linguistic gestures and vocal expressions.…

This study deals with speech acts addressed to Hadza infants in Tanzania, a group that has traditionally lived off hunting and gathering. Three research questions are addressed: How do Hadza speech acts compare with those found in previous studies in other cultures? Are there differences between child and adult speakers? And do speech acts differ…

Children are known to use different types of referential gestures (e.g., deictic, iconic) from a very young age. In contrast, their use of non-referential gestures is not well established. This study investigated the use of "stroke-defined non-referential" 'beat' gestures in a story-retelling and an exposition task by twelve 6-year-olds,…

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 article investigates the amount of input and the quality of mother-child interactions in mothers who differ in socio-economic status (SES): mid-to-high SES (mhSES) and low SES. The amount of input was measured as the number of utterances per hour, the total duration of speech per hour and the number of turns per hour. The quality of the…

Given the dependent nature of parent-infant interactions necessary for language development, it is important to understand how context may influence these interactions. This study examines how contextual variables influence communicative, cognitive and social measures of parent-infant interactions. Specifically, how do feedback toys and…

Bookreading is known to benefit young children's language and literacy development. However, research has demonstrated that how adults interact around a book with a child is probably even more important than reading the complete text. Dialogic or interactive reading strategies can promote children's language development more specifically. Little…

Many ancestral languages (AL) are at imminent risk of extinction due to societal changes that pressure minority communities to assimilate with dominant cultures and forego usage of their AL. This study aimed to encourage caregiver-child dyads to converse in Lazuri, an endangered AL in Rize, Turkey. Dyads (N = 59; child age M = 30.7 months, range…

Infants' prelinguistic vocalizations and gestures are rarely studied as a communicative system. As a result, there are few studies examining mechanisms of change concurrently in prelinguistic vocal and gesture behavior. Here we report the first evidence that contingent caregiver social feedback to infant gestures influences not only gesture…

This study examined lexical-phonological interactions in the first 50 words of a group of monolingual German- and Spanish-speaking children and bilingual German--Spanish children. The phonological characteristics of the earliest target word forms and output patterns of these children were analyzed to determine whether bilingual children select…

To become successful communicators, children must be sensitive to the clarity/ambiguity of language. Significant gains in children's ability to detect communicative ambiguity occur during the early school-age years. However, little is known about the cognitive abilities that support this development. Relations between cognitive flexibility and…

Thirty infants at 1;1 and their mothers were videotaped while playing for 18 minutes. Experimental stimuli were presented in three communicative intent contexts--proto-declarative, proto-imperative, and ambiguous--to elicit infant communicative bids that did and did not contain gestures. Mothers' responses were analyzed, and their verbal responses…

Early shared book reading activities are considered to be a promising context for supporting young children's language development. Ninety low socioeconomic status preschoolers and their mothers were randomly assigned to one of three groups: (1) e-book reading; (2) printed book reading; (3) regular kindergarten literacy program (control). Mothers…

This article investigates the contribution of maternal mediation in storybook reading, socioeconomic status (SES), and home literacy environment (HLE) to children's literacy level in kindergarten and first grade in Israeli Arabic-speaking families. A total of 109 kindergarten children and their mothers participated. Children's literacy level was…
