Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

Current theories of phonological development make contrasting predictions about the role of vocabulary growth and orthographic knowledge in the emergence of segmental phonological representations. Testing these predictions in children is made difficult by the metacognitive nature of tasks used to assess phonological representations. In this study,…

In this study, we explored the role of emerging inhibitory control skills in language acquisition in 62 typically developing children aged 24-32 months and investigated whether early inhibitory control skills are longitudinally associated with language outcome. Specifically, we focused on two different inhibitory processes that develop…

We report on an analysis of spontaneous gesture production in 2-year-old children who come from three countries (Italy, United Kingdom, Australia) and who speak two languages (Italian, English), in an attempt to tease apart the influence of language and culture when comparing children from different cultural and linguistic environments.…

The loss of a childhood language, especially in adoptees, has attracted scholars' attention in the past, but a search for any memory traces has yielded conflicting results. In a psycholinguistic tradition known as the savings paradigm, a learn-and-relearn technique is employed to examine whether the relearning of lexical items once known, often in…

Variability in achievement across learners is a hallmark of second language (L2) learning, especially in academic-based learning. The Twins Early Development Study (TEDS), based on a large, population-representative sample in the United Kingdom, provides the first opportunity to examine individual differences in second language achievement in a…

Patterns of growth in one language in relation to growth in the other and also with respect to growth in both languages were studied in a group of 20 bilingual (English/Spanish) infants ages 10 to 30 months. The rate and pace of development were similar in both groups; differences among the bilinguals included their use of "referential"…

Administered the MacArthur Communicative Development Inventory to 25 bilingual (English/Spanish) and 35 monolingual children who were furnishing data for longitudinal study. Assessment of the degree of overlap between bilingual children's lexical development in their two languages showed that they developed early vocabulary at the same rate as…

Presents a case study of a bilingual two-year-old, documenting his translation skills between the age of 1 year, 11 months and 2 years, 5 months. Argues that critical insights into child language may be gained through the examination of a child's linguistic abilities in cognitively demanding situations. (SED)
