Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

Recent research has demonstrated that individual differences in infant attention to faces and voices of women speaking predict language outcomes in childhood. These findings have been generated using two new audiovisual attention assessments appropriate for infants and young children, the Multisensory Attention Assessment Protocol (MAAP) and the…

A significant body of literature has demonstrated that infants demonstrate a decline in sensitivity to nonnative sound contrasts by their first birthday, a transition often thought to be adaptive for later word learning. The present study investigated infants' sensitivity to these contrasts in a habituation-based discrimination and word learning…

Bilingual children have been shown to differ from monolingual children in several domains of human cognition. Comparatively few studies have investigated social-interactional processes in bilingual populations. Here, we investigated whether monolingual and bilingual children demonstrate similar susceptibility to an aspect of social functioning…

A talking face provides redundant cues on the mouth that might support language learning and highly salient social cues in the eyes. What drives children's looking toward the mouth versus eyes of a talking face? This study reports data from 292 children who viewed faces speaking English, French, and Russian. We investigated the impact of…

Does the language we speak affect the way we think, and if so, how? Previous researchers have considered this question by exploring the cognitive abilities of speakers of different languages. In the present study, we looked for evidence of linguistic relativity within a language and within participants by looking at memory recall for monolingual…

Three experiments investigated 5- to 6-year-old monolingual English-speaking American children's sociolinguistic evaluations of others based on their accent (native, foreign) and social actions (nice, mean, neutral). In Experiment 1, children expressed social preferences for native-accented English speakers over foreign-accented speakers, and they…

This study utilized latent growth-curve analyses to determine if the early literacy skills of children who were Spanish-speaking language-minority (LM) followed a similar quantitative growth profile over a preschool year as that of a group of children from a comparable socioeconomic (SES) background but who were not LM. Participants, who ranged in…

Research based on naturalistic and checklist methods has revealed differences between English and Chinese monolingual children in their trajectories of learning nouns and verbs. However, studies based on controlled laboratory designs (e.g., Imai et al., 2008) have yielded a more mixed picture. Guided by a multidimensional view of word learning (in…

Examined the understanding of general correspondences between print and language and specific correspondences in alphabetic and nonalphabetic languages on the part of monolingual (English) and bilingual (French-English, Chinese-English) 4- and 5-year-olds. Bilingual children understood the general symbolic representation of print better than…

Examined understanding of print concepts in preschool children bilingual in English and Hebrew. Found that bilingual children were more advanced than monolinguals, regardless of task (understanding that a printed word's meaning did not change if moved to a new location, making judgments about word length and ignoring the object's size) or whether…
