Within developmental psychology, pointing gestures have received a great deal of attention, while ostensive gestures have been overlooked in terms of their emergence and intentionality. In a longitudinal and micro-genetic study with six children at 9, 11, and 13 months of age, we codified gesture production of children within second-by-second data…

This article presents data on lexical development of 881 Israeli Hebrew-speaking monolingual toddlers ages 1;0 to 2;0. A Web-based version of the Hebrew MacArthur-Bates Communicative Development Inventories (H-MB-CDI) was used for data collection. Growth curves for expressive vocabulary, receptive vocabulary, actions and gestures were…

Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency,…

(2017) have proposed that variations in the timing, quality and quantity of language input during the earliest stages of development are related to variations in the development of phonological working memory and, in turn, to later language learning outcomes. To examine this hypothesis, three groups of children who are…

To investigate the apparent delay in color naming by young children, this study compared natural-kind and color naming (and corresponding comprehension) by 48 young English children who completed testing four times over six weeks. Results indicated that, as opposed to the salience view, the apparent delay in color naming may be explained solely on…

Compared expressive vocabulary data from a systematic diary study of one child's early language development with data from longitudinal administration of the MacArthur Communicative Development Inventories spoken vocabulary checklist (CDI). The CDI underestimated the number of words in the diary study. Logistic curves were the best-fitting model…

Investigated whether low-income mothers learned to interact with their preschoolers in ways that fostered narrative skills. Mothers of intervention children were encouraged to elicit questions, encourage longer narratives, and participate in narrative conversation. Assessment of children's pre- and post-intervention narrative and vocabulary skills…
