Evidence suggests that the quantity of linguistic input experienced by infants in early childhood centres relates to the quality of educator-infant interactions. However, little is known about the linguistic properties of mutually responsive educator-infant interactions. This study uses sequence analyses to identify patterns of educator-infant…

This article examines phonological development and its relationship to input statistics. Using novel data from a longitudinal corpus of spontaneous child speech in Polish, we evaluate and compare the predictions of a variety of input-based phonotactic models for syllable structure acquisition. We find that many commonly examined input statistics…

Differences in vocabulary that children bring with them to school can be traced back to the gestures they produced at the age of 1;2, which, in turn, can be traced back to the gestures their parents produced at the same age (Rowe & Goldin-Meadow, 2009a).

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…
