In a preferential looking paradigm, we studied how children's looking behavior and pupillary response were modulated by the degree of phonological mismatch between the correct label of a target referent and its manipulated form. We manipulated degree of mismatch by introducing one or more featural changes to the target label. Both looking behavior and pupillary response were sensitive to degree of mismatch, corroborating previous studies that found differential responses in one or the other measure. Using time-course analyses, we present for the first time results demonstrating full separability among conditions (detecting difference not only between one vs. more, but also between two and three featural changes). Furthermore, the correct labels and small featural changes were associated with stable target preference, while large featural changes were associated with oscillating looking behavior, suggesting significant shifts in looking preference over time. These findings further support and extend the notion that early words are represented in great detail, containing subphonemic information.
Language development in children with a heritage language background is often characterized by a shift towards the majority language once children enter formal educational contexts.
In Germany, educational programs that target heritage languages are scarce.
It is therefore of interest whether children with a heritage language background can benefit from a bilingual program targeting their heritage language.
In this paper, we report data on the lexical skills of Italian heritage children in two educational contexts, bilingual Italian-German kindergartens and a bilingual Italian-German elementary school.
We examine (1) developmental trajectories of children's lexical skills in German and Italian, (2) differences between noun and verb development, (3) differences between lexical production and comprehenand Italian, kindergarteners showed balanced receptive vocabulary skills.
By contrast, elementary school-children had a larger German than Italian vocabulary. Both groups demonstrated a clear dominance of nouns over verbs.
While school children already performed at ceiling in German at the end of first grade, across the school years, their Italian vocabulary increased, nouns in particular.
Consonants have been proposed to carry more of the weight of lexical processing than vowels. This consonant bias has consistently been found in adults and has been proposed to facilitate early language acquisition. We explore the origins of this bias over the course of development and in infants learning different languages. Although the consonant bias was originally thought to be present at birth, evidence suggests that it arises from the early stages of phonological and (pre-)lexical acquisition. We discuss two theories that account for the acquisition of the consonant bias: the lexical and acoustic-phonetic hypotheses.
