Two cognitive tasks of physical uncertainty were used to assign 56 subjects (aged 5 to 17 years) to one of three cognitive stages. Two tests for comprehension of speaker uncertainty were then administered to all participants. Results were interpreted as showing that development of cognitive stages is structurally related to comprehension of speech…

Reports on experiments examining the semantic organization of concrete nouns and verbs and its development in childhood. Differences in semantic organization are said to be a clue to age-related changes in performance with verbs. (AM)

Reports on research on the acquisition of adjectives vs inflectional endings in Italian children. Patterns resulting from a longitudinal study involving two children and an experiment involving 84 children are compared to patterns of adults participating in the latter experiment. (Author/AM)

Examines a corpus of narratives produced by preschool children, and focuses on differences among the three age groups with respect to: (1) complexity, (2) the relationship between story elements and the discursive context, (3) relationship between story elements and extralinguistic context, and (4) shaping of the narrative as story and as part of…

A multiple-choice test, involving college students, showed that an ability to recognize biological terms was to some extent independent of the ability to understand the ideas to which they referred. Thus, there could be an appreciation of biological concepts and principles in the absence of the accepted vocabulary. (BB)

In two experiments, 5-, 7-, and 11-year-old children and college students were presented on each trial with a sentence followed by a probe word. The children's task was to indicate whether the probe was in the sentence or not. (MS)

To explore adjective language development and examine its relationship to seriation, several tasks were given to 40 children aged 4-8. Comprehension and production of adjective forms were measured--vocabulary, coordination, comparison. Ability to order objects by size was used to assess intuitive-level seriation. (CHK)

Fourteen two-year-olds were presented with minimal word pairs in a new and efficient experimental perception paradigm. Data provide a view of relative difficulty of various minimal phonological contrasts for children. (CHK)

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)

Experiments in eliciting true/false judgments from young children aged 3-5 used a "talking doll," a toy panda with a speaker installed. The procedure has been used in studies of language comprehension, communication skills, and free conversation experiments. (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)

Children aged 2 1/2-4 were asked questions containing comparative and superlative forms of adjectives in pairs designated as unmarked/marked or positive/negative. Differences in frequency of correct responses were greater between unmarked/marked pairs than between positive/negative pairs. No evidence appeared for a marking explanation of adjective…

This paper outlines a proposal to cover four very early stages for the acquisition of negation systems in natural languages. It emphasizes the formal linguistic devices as the major variables that determine the various language-specific developmental sequences. (CHK)

Examined young children's language productivity with newly learned forms by teaching them four new words: two nouns and two verbs. Findings indicate children combined the novel nouns productively with already known words much more often than they did the novel verbs--by many orders of magnitude and several children pluralized the new nouns,…

Reviews current understanding of the process of emergent literacy development for linguistically diverse children. Claims that process of literacy development can be viewed as a sequential developmental task. Also explains that children create principles or hypotheses to develop literacy specific to their understanding of their native language and…
