Data from four recent language studies are examined to explore issues in concept-word relationships. Issues considered include: lexical development, bases of application, single-word functions, semantic domains, categorizing through naming, and concept matching as a model of word learning. (JMB)

Argues that inferring the intension (meaning) of children's words solely from the words' extension (referential scope) is problematic and describes two studies of the intension of children's words which involve a different approach. (JMB)

Discusses relevance of language acquisition and use to educational practice and the student's school performance. (GB)

McCaig's article, "How Not To Analyze the Syntax of Children," appears in this issue, pp. 612-18. (SW)

Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

This study introduces a typological model of the "conceptual language-specific approach" to the L2 research on the acquisition of tense-aspect. The model is based on the typological notion of prominence, classifying languages into tense-prominent and aspect-prominent (Bhat 1999) and the L1 research proposal that language-specific…

In addition to componential aspects of verb meaning, children must also acquire a representation of each verb's combinatorial properties or propositional schema, i.e., the number of arguments with which it is obligatorily or optionally associated. The present study investigated developmental changes in children's awareness of the combinatorial…

The spontaneous speech of two Zulu girls was monitored for use of nominals. The data for one girl, 23 months, are reported in detail. Analysis of prefixed and prefixless nouns in isolated citation forms and in syntactic construction revealed that the child perceived the internal structure of nouns before the age of two, although the prefix often…

Children ranging in age from 1;1 to 1;3 were presented with 16 contrived lexical concepts, each consisting of a nonsense word (eight object words and eight action words) and four unfamiliar exemplars that served as the referents for that word. Overall, the children used 65% of the experimental words one or more times to refer to at least one of…

Four words that cause the highest incidence of error in the English language are discussed. (CK)

One child's unique phonological rule is reported, which increased output variety and still yielded a mismatch with the adult form. It is argued that an addition to the strategies described by Menn is needed to account for the discovery of this rule and for later stages of phonological development. (Author)

Analysis of a database of tag questions in children's speech shed light on their structure and function. (JB)

Argues against Youssef's treatise which pointed out some difficulties in attempting to test Bickerton's language bioprogram hypothesis (LBH), contending that the treatise seriously misunderstood certain key concepts of the LBH and dismissed with questionable reasoning some important findings which supported the state/process distinction as a…

Edwards (1992c) concerns data and data use rather than manuals. It presents principles to facilitate reliable archive research in an imperfect world. MacWhinney and Snow (1992) endorse the principles but disagree on important details, discussed in this response. (21 references) (KM)
