Most children between 18 and 24 months can say about 50 words and understand hundreds more. While children a few months younger use single words to label objects and people, the one- and two-word phrases children use at this age show the beginnings of what they call "stories"--children's expressions of their desires, descriptions of what they see,…

This study examines infants' joint attention behavior and language development in a rural village in Nigeria. Participants included eight younger (1;0 to 1;5, M age=1;2) and eight older toddlers (1;7 to 2;7, M age=2;1). Joint attention behaviors in social interaction contexts were recorded and coded at two time points six months apart. Analyses…

The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

The purpose of this study was to examine changes in prelinguistic vocal production during the first 20 months of life. Vocalizations were classified into 23 mutually exclusive and exhaustive types, and grouped into five ascending levels using the Stark Assessment of Early Vocal Development-Revised (SAEVD-R). Data from 30 typically developing…

The study to be reported in this paper examined the work accomplished by "mm" and "mm hm" in the interactions of a parent and his daughter aged 0;10-2;0. Using the findings of Gardner (2001) for adults, the analysis shows that "mm" accomplished a range of functions based on its sequential placement and prosodic features, whereas "mm hm" was much…

This study documents the development of symbolic, spatial, and temporal displacement of toddler's speech. Fifty-six children and their mothers were observed longitudinally 5 times from 18 to 30 months of age during a staged communication play while they engaged in scenes that encouraged interacting, requesting, and commenting and scenes that…

Examination of the relationship between linguistic forms and the functions they serve in one- to two-year-olds' (N=6) early talk about agentivity and control found that the subjects systematically employed different self reference forms to mark distinct perspectives on agency. 34 references.

Examined the evolution of visual perspective-taking skills in relation to comprehension and production of first, second, and third person pronouns among French and English speaking toddlers. Some perceptual perspective-taking capacities were well developed by the time children acquired a full mastery of personal pronouns. Full pronoun acquisition…

The acquisition of noun gender on articles was studied in a sample of 21 young German-speaking children. Longitudinal spontaneous speech data were used. Data analysis is based on 22 two-hourly speech samples per child from 6 children between 1 ; 4 and 3 ; 8 and on 5 two-hourly speech samples per child from 15 children between 1 ; 4 and 2 ; 10. The…

Examined young children's acquisition of wh-questions. Children heard a wh-question and attempted to repeat it; a "talking bear" answered. The same format was used for two intervention sessions for children in a quasicontrol condition. Suggests very little input--if concentrated and varied and presented so the child attends to it and…

Relative importance of appearance and potential function in children's object naming was examined. First, 16 children, taught novel names for unfamiliar objects, had to decide whether these applied to items that resembled the training objects in appearance or potential function. Then the name training procedure was revised so that equal emphasis…

Tested the prediction that "yes-no" questions that place forms of the copula "be" in initial position will also increase the rate of growth of children's copula verb development. Data from 33 children who were matched for stage of language development at 1;9 and 2;0 confirm that the frequency of inverted copulas in yes-no…

Examined use of word order and animacy for interpretation of sentences by typically-developing and language delayed children. Results indicate that typically-developing 2-year-olds use neither cue consistently to interpret sentences; typically-developing 2.5-year-olds used a coalition of word order and animacy cues; and language-delayed…

Language development is often slower in preterm children compared with their term peers. We investigated factors associated with vocabulary acquisition at 2 years in a cohort of children born at 28 weeks' gestation or less. For children entered into the United Kingdom Oscillation Study, language development was evaluated by using the…

Purpose: Language and speech are difficult to assess in newly arrived internationally adopted children. The purpose of this study was to determine if assessments completed when toddlers were first adopted could predict language outcomes at age 2. Local norms were used to develop early intervention guidelines that were evaluated against age 2…
