In addition to serving as question markers with interrogative force, "wh"-words such as "shenme" "what" in Mandarin Chinese have a noninterrogative meaning. For the noninterrogative meaning, these words have been typically analyzed as negative polarity items, i.e., as "wh"-pronouns that are similar in…

This article reports a research project, where two pairs of children were recorded in discussion, first in Year One and then five years later in Year Six. A unique opportunity meant that the children engaged in the same task at the beginning and end of their Primary School education. The research analyses the talk on three levels, considering the…

Priming methodology was previously used to investigate children's ability to represent abstract syntactic forms. Existing evidence indicates that following exposure to a particular syntactic structure (such as the passive voice), English-speaking children increase their production of that structure with new lexical items. In the present work, we…

The present study explores the vocabulary development of bilingual children when neither of their languages has a minority language status. With both languages having high relative prestige, it is possible to address the impact of exposure variables: age of onset, length of exposure, and frequency of exposure (FoE) to both languages. Parents of 40…

This article questions how two very similar sets of experiments can yield such very different findings, and comments on the differences between the studies. Here Annamarie Kerkhoff presents a commentary on some perceived differences between the studies in areas such as age groups and group sizes evaluated. Kerkhoff also comments on some…

What are the sources of variation in the input, and how much do they matter for language acquisition? This study examines frequency variation in manner-of-articulation classes in child and adult input. The null hypothesis is that segmental frequency distributions of language varieties are unigram (modelable by stationary, ergodic processes), and…

The impact of input frequency (IF) and functional load (FL) of segments in the ambient language on the acquisition order of word-initial consonants is investigated. Several definitions of IF/FL are compared and implemented. The impact of IF/FL and their components are computed using a longitudinal corpus of interactions between thirty…

Children with pre/perinatal unilateral brain lesions (PL) show remarkable plasticity for language development. Is this plasticity characterized by the same developmental trajectory that characterizes typically developing (TD) children, with gesture leading the way into speech? We explored this question, comparing eleven children with PL -- matched…

This is a naturalistic study of the development of language in Hebrew-speaking children with Williams syndrome (WS) and children with Down syndrome (DS), whose MLU extended from 1[multiplied by]0 to 4[multiplied by]4. Developmental curves over the entire span of data collection revealed minor differences between children with WS, children with DS,…

The study aims to account for the distribution of finite versus non-finite verbs during a developmental period when children use both types of verb forms in contexts requiring finiteness. To meet this goal, longitudinal samples from three Hebrew-acquiring children (aged 1;4-2;6) are examined from the onset of verb production and across the…

The primary purpose of this study was to compare language and narrative skills of both talented and regular young children in Taiwan. The participants were asked to tell a story based on images in children's picture books. Twelve children, who participated in a screening session designed to identify young talented children for the Enrichment…

How do children acquire African American English? How do they develop the specific language patterns of their communities? Drawing on spontaneous speech samples and data from structured elicitation tasks, this book explains the developmental trends in the children's language. It examines topics such as the development of tense/aspect marking,…

This four-wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age-appropriate multisource measures of child language on single-factor core language skills at 20 months and 4, 10, and 14 years. Large stability…

For professionals working with multilingual children, detecting language deficits in a child's home language can present a challenge. This is largely due to the scarcity of standardized assessments in many children's home languages and missing normative data on multilingual language acquisition. A common approach is to translate existing English…

This study investigated the role of parenting knowledge of infant development in children's subsequent language and pre-literacy skills among White, Black and Latino families of varying socioeconomic status. Data come from 6,150 participants in the Early Childhood Longitudinal Study-Birth Cohort. Mothers' knowledge of infant development was…
