We investigate whether child-directed speech (CDS) contains a higher proportion of canonical pronunciations compared to adult-directed speech (ADS), focusing on Korean noun stem-final obstruent variation. In a word-teaching task, we observed that mothers use a higher rate of canonical pronunciation when addressing infants than when addressing…

This study analyses variation sets in a sample of child-directed speech (CDS) in Turkish in terms of their structure and effect on child speech. The term "variation set" was first introduced to describe the sequences of repetitions, in which the intention behind expressions stays the same throughout the whole conversation while the form…

To what extent can language acquisition be explained in terms of different associative learning mechanisms? It has been hypothesized that distributional regularities in spoken languages are strong enough to elicit statistical learning about dependencies among speech units. Distributional regularities could be a useful cue for word learning even…

Research on sources of individual difference in parental Infant-Directed Speech (IDS) is limited and there is a particular lack of research on fathers' compared to mothers' speech. This study examined the predictive relations between infant characteristics and variability in paternal lexical diversity (LD) in dyadic free play with two-year-olds (M…

As infant/toddler programs encounter growing diversity, they need to reenvision the impact they have on children and families in all areas of practice, from recruiting new enrollees to stocking classrooms to changing the ways adults interact with children and families with different languages and from different cultures. What happens on the first…

Argues that evolution of the phonological systems of natural languages and the typology of distinctive features is based on perceptual discontinuities of the auditory system. It is suggested that neonates rely on these innate sensitivities for acquisition of sound systems and that some phonological variation in early child phonology results from…

Examines the phonetic characteristics of babbling by a pair of fraternal twins raised in a bilingual environment (English/Serbian). The study focused on the basic articulatory form of babbling, the impact of twinship on babbling patterns, and whether effects specific to one or another of the ambient languages could be observed. (30 references)…

Models the spread of linguistic change by taking account of the ages of the acquirers and transmitters of change. The article focuses on three interlocutor combinations: parent-infant/young child, peer group-preadolescent and older adolescent/adult-adolescent. Findings suggest that borrowings are the easiest to acquire, while lexically…
