Two studies were conducted, one to judge the relative ages of pairs of vocalizations from Chinese and American infants of varying ages, the other to judge the linguistic community of the vocalizer when age was held constant. Judgments were highly accurate in the first study, but not in the second. (Author/RM)

In a previous paper, J. Hurford accounts for errors in children's question forms by postulating that children incorrectly internalize adult rules. This article suggests that this rule is inconsistent and unjestified, and that such errors are due to segmentation problems and processing limitations. (CHK)

This article criticizes a previous paper that stressed a transformational analysis of children's question acquisition. It is argued that a surface structure generalization analysis makes empirically correct predictions about mistakes both in acquisition of inverted word order and in the form of "wh" questions. (CHK)

A child with chronic otitis media with effusion solved the problem of reduced and fluctuating auditory input with phonological selection and avoidance strategies that capitalized on prosodic cues. Findings illustrate the need to consider interactions among performance, input, and linguistic constraints to explain individual variation in language…

Verb forms used by 14 4-year-olds in their pretend play were investigated in a study of the use of past verb forms to express "unreality." Results suggest that different past verb forms co-occur with different play activities; e.g., present perfect occurring when children implement their plans and communicate within an already…

Data from 48 infants revealed (1) that infants aged 1;2-2;3 failed to establish a stable word-object link even in follow-in labeling and (2) that only infants aged 1;6-1;7 could identify the correct referent during discrepant labeling. During the period between 1;2-1;7 infants are becoming increasingly adept at acquiring new labels under minimal…

The speech of two mothers to their infants between three and eighteen months was analyzed. Simplicity of speech was about the same at all ages, not showing abrupt change as children began to talk. It is suggested that mothers used a conversational model and changes reflect children's growing conversational ability. (CHK)

This paper reports on a case study of a Cantonese-speaking child age 2 and considers the implication of tone acquisition for tone studies in general, and Cantonese tonology in particular. (NCR)

A phenomenon called "pragmatic variation" is discussed as a child's individual system of behavior in response to a question the child doesn't understand but realizes that he must verbalize an answer to. (NCR)

In testing kindergartners and first graders in their comprehension of the words "before" and "after," it was found that when temporal terms are acquired, they are first used as prepositions and then as subordinating conjunctions. (Author/NCR)

Preschool children's comprehension of the adverbial modifiers "very" and "sort of" was experimentally investigated in 64 children. (Author/NCR)

This experiment used two groups of preschoolers and one group of young grade-schoolers to test for their comprehension of presuppositions and negation in complex syntax. (NCR)

Describes the transition from single to multiple word utterances in one child. The development illustrates the initial dissociation and later coordination of the temporal chaining of elements and meaning relatedness between elements and also the importance of repetition for the change from single-word utterances to meaning-related, multiword…

Examination of a two-year-old's early determiner-noun combinations suggested that early article use can be distributed across a variety of nouns, and that such usage does not seem appropriately characterized as a pattern of limited semantic scope. (CB)

Command of transitivity permutations in Hebrew, where a change in verb-argument syntax entails a change in verb morphology, were examined in 30 children aged 2, 3, and 8. Findings have implications for the development of derivational morphology, item-based versus class-based learning, and the impact of lexical productivity and language-particular…
