The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

Joint attention between hearing children and their caregivers is typically achieved when the adult provides spoken, auditory linguistic input that relates to the child's current visual focus of attention. Deaf children interacting through sign language must learn to continually switch visual attention between people and objects in order to achieve…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

Previous studies indicate that the acoustic features of speech discriminate between positive and negative communicative intentions, such as approval and prohibition. Two studies investigated whether acoustic features of speech can discriminate between two positive communicative intentions: humour and sweet-sincerity, where sweet-sincerity involved…

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…

Investigated the relationship between language competence, joint attention, and interaction between mothers and toddlers that fosters joint attention. Found no correlation between joint attention and concurrent language, yet joint attention was related to toddler age when correlated with language. Suggested that nonostensive settings need further…

Changes in mothers' strategies for eliciting verbal responses (EVR's) as a function of child age were investigated in this study. Seven mother-child dyads were observed in their homes when the children were 16, 21, 24, 30, and 34 months of age. Mother EVR's were coded according to syntactic form, type of cue for child response, and complexity of…

In two experiments, mothers told their infant and an adult a story that involved target words, and women taught an assembly procedure involving novel terminology to another adult. In speech to infants, mothers positioned focused words on pitch peaks, but in speech to adults, the emphasis was more variable. (BC)
