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,…

Examines the possibility that bilingual experience in infancy may affect the unfolding of vocal precursors to speech. The results of this longitudinal study indicate that infants reared in bilingual and monolingual environments manifested similar ages of onset for canonical babbling (production of well-formed syllables), an event fundamentally…

Examines the acquisition of new sound changes by 3- and 4-year-old children in asymmetrical child care situations. Results reveal that the children had acquired the changes and emphasize that the dialect transmission period begins before the age of maximal peer group influence. The findings support the possibility that child care asymmetry affects…

The influence of information level on the production of accuracy of 20 children was examined. Data were children's productions of nouns in sets of utterances referring to triplets of pictures representing noun-verb-noun utterances. (Author/JL)

Notes that psycholinguists have studied "fast mapping," and behavior analysts have studied the phenomenon of"learning by exclusion." Reviews the research protocols, questions, and outcomes of these two research lines to show their clear similarities, to support the argument that both disciplines are studying a single…

Reports on the continuing study of a congenitally acochlear child using an analytical focus on the prelinguistic vocalizations involving the description of syllable groupings within a prosodic hierarchy. Results indicate that audition is not necessary for the formation of prelinguistic phrasing, but hearing does influence certain aspects of…

Presents evidence that the supposed paradox in which infants find abstract patterns in speech-like stimuli whereas even some preschoolers struggle to find abstract syntactic patterns within meaningful language is no paradox. Asserts that all research evidence shows that young children's syntactic constructions become abstract in a piecemeal…

Asserts that the posited paradox between infancy and toddlerhood language was not eliminated by Tomasello and Akhtar's appeal to infants' robust statistical learning abilities. Maintains that scrutiny of their studies supports the resolution that abstracting linguistic form is easy for infants and that toddlers find it difficult to integrate…

Details an investigation of language development and subsequent readiness to learn of preschoolers in a disadvantaged Griqua community in South Africa. Notes that preschoolers revealed a relative lack of verbal fluency, associative reasoning, and relational thinking skills, and had a restricted vocabulary. Argues that inadequate language…

Presents an alternative definition of negative evidence, based on the idea that the unique discourse structure created in the juxtaposition of child error and adult correct form can reveal the child in contrast or conflict between the two forms. Findings reveal that children reproduced the correct irregular model more often and persisted with…

Examines different approaches to prosodic acquisition: Gerken's S(W) production template; Fikkert's and Archibald's theories of stress acquisition and Demuth and Fee's prosodic hierarchy account. Results reveal that current approaches cannot account for findings in the data such as the increased preservation of final over nonfinal unstressed…

Explores how the discourse context of metaphorical language supports children's understanding of sociocultural norms. Classroom data are examined to determine how language, situation, and interaction assist in the interpretation of metaphorically used language. (46 references) (Author/CK)

Considers the relevance of the points raised in the preceding articles in this issue to the sociolinguistic development of children with speech and language impairments. Notes that such children often have low self-esteem and that their inability to negotiate an identity for themselves through discussion with their peers may contribute to this…
