A validation study of five checklists for assessing two-year-olds' word production revealed that the lists produced comparable mean production scores, reflected age differences, and preserved individual differences in total production and in production of linguistic categories such as nouns, verbs, open class items, and closed class items.…

Investigated overextensions in comprehension and production, using the preferential-looking model, in 99 children (ages 1;9 to 2;3) who were asked to find the referent that matched the label they were given in real and anomalous trials. Results confirm that overextensions in production are not diagnostic of children's underlying semantic…

This study examined adult and child word-initial voice onset time productions in English and Hindi to determine the age of acquisition of the phonemic voice contrast. Cross-linguistic differences in patterns of acquisition were found, but these were not necessarily traced to the different phonological systems. (JL)

Investigates how early a developing bilingual who is exposed simultaneously to English and Spanish can make appropriate language choices. Kept detailed records of the child's cumulative vocabulary from the first word at 10 months and on weekly audiovideo recording in both Spanish and English contexts from age 1-3. (Author/VWL)

Examined children's generalization of familiar verbs to novel events. Findings reveal children aged 1;8 with the largest expressive vocabulary generalized the same verbs to actions with different agents, but not to actions different in outcome or manner of action and children aged 2;2 extended familiar action verbs to other actions different in…

Examined miscommunication episodes occurring between 2.5-year-olds and their parents during videotaped free play sessions. Although children generally responded appropriately in form to parental clarification requests, they responded more often to and resolved successfully more of those following their own requests than those following their…

The speech children spontaneously quote was examined in 2 studies involving personal narratives from 96 children aged 4 to 9 and speech in 25 children aged 1 to 5. Findings showed that frequency of reported speech increased with age and direct quotation was more common than indirect or summarized quotations at all ages. (57 references) (Author/LB)

The development of forms and functions of negation in parent-child interactions in the early stages of language acquisition is discussed with illustrative examples from field data relating to two Tamil-speaking children and their parents. An attempt is made to provide a scheme for analyzing the negatives in children's speech. (18 references) (JL)

Examines the development of children's understanding of the difference between "want" and "need" in two different experiments. The first experiment required the children to respond verbally in choosing between the two concepts; the second required them to give an object to one of two characters who had made a request using…

Many recent generativist models attribute grammatical knowledge to young children on the basis that children's language patterns the same way as the target adult language. It has been proposed that the child acquires this knowledge early on in development by a process of parameter setting. Wexler (1996) presents the "Very Early Parameter Setting…

Analysis of parent language with toddlers with three different types of toys found few differences as a function of parent or child gender. The three contexts elicited their own language patterns and suggested that children who play frequently with dolls receive more opportunities to learn and practice language. (Author/CB)

This study assessed the relative merits of adult-like syntactic and limited scope formula accounts of children's early determiner use to evaluate the claim that children can be said to be operating with a syntactic determiner category early in development. The study focuses specifically on Valian's (1986) criteria for attributing the syntactic…

Investigates comprehension of metaphoric compounds. The study asked children and adults to identify referents of various types of these compounds. Findings reveal that 5-year-olds outperformed 3-year-olds but performed significantly less well than adults and that 3-year-olds did not generally interpret the compounds literally. (37 references)…

Data from two-year-old children and mothers were collected concerning age at which she began to read to child, frequency of home reading, number of stories read per week, frequency of visits by child to library. Picture-book reading exposure was more strongly related to receptive than expressive language. Age of onset of home reading routines was…

Analyzes monolingual Spanish- and German-speaking children's production of target consonant clusters at early stages of acquisition from a phonological representational perspective. At the beginning stages, target clusters are reduced to a single consonantal position, due to lack of branching of the syllable constituents. At later stages, cluster…
