Responds to four commentaries on the article by Jones and Smith in this issue. Suggests that the comments derive from the possibility that stable concepts might not exist and from the difficulty of imagining what cognition could be without represented concepts. Discusses traditional approaches to stability and variability, and considers what…

Fundamental frequency, duration, and amplitude measures were extracted from stressed and unstressed syllables in interword and intraword comparisons. Analysis of target stress patterns revealed no difference between acoustic marking of stress by 6 adults and 22 toddlers. Findings indicate that children generally control these variables to derive…

Investigated the actionality effect in 48 French-speaking children (ages 5;0 to 7;11) by systematically varying the voice of the test sentences and the voice of the interpretive requests. The interaction between actionality, voice of sentence, and interpretive request revealed that the actionality effect depended on the type of task used to assess…

This commentary responds to an article by Rebecca McCathren and others on using directives in early language intervention. It suggests that the primary effect of follow-in directives may be to set the tone of the interaction. Factors that affect the relationship between responsiveness and directiveness are addressed, including sequencing, rhythm,…

This study examined the influence of metrical patterns (syllable stress and serial position) of words on the production accuracy of 20 children (ages 22 months to 28 months). Among results were that one-fourth of the initial unstressed syllables were omitted and that consonant omissions, though few, tended to occur in the initial position.…

This article examines the acquisition of wh-questions and relative clauses in Sesotho, a language with no wh-movement in either questions or relatives, and in which wh-questions must be clefted. (10 references) (JL)

Varying definitions of formulas, or apparently nonproductive utterances in children's speech, are compared, and criteria for formula recognition are reviewed. A preference rule system is proposed, which distinguishes conditions for formula recognition. Formulas found in the data of one child acquiring Irish are examined. (29 references) (KM)

This study shows that the noun bias in early vocabularies rests only in part on the acquisition of object names. An analysis of vocabulary composition from 45 children at I;8 indicates that more nouns are acquired than all other word classes but that only about half of the nouns acquired are the names of basic level object classes (BLOCs). (KM)

This study explores the spontaneous acquisition of Italian inflectional morphology by three children. Longitudinal, free speech samples are examined, focusing on the development of the morphological paradigms of Italian verbs, pronouns, and articles. (80 references) (JL)

This study explores the role that gesture plays in the earliest stages of language learning. A description is provided of how one-word speakers use gesture in combination in combination with speech in their spontaneous communications and interpret gesture presented in combination with speech in an experimental situation. (JL)

Seventeen preschool children, 26 kindergarten, and 26 fourth grade childrens' knowledge structures were examined with a word association task and a match-to-sample picture task to determine whether or not children used slot-filler categories as a mediating structure between event-based and taxonomic knowledge structures as proposed by Nelson…

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations. (LB)

Investigates the claim that very young children avoid backwards coreference in their interpretation of sentences containing pronouns. It is argued that children initially prefer internal coreference even when such a response is disallowed for structural reasons and that avoidance appears to be a late developing phenomenon characteristic of…

Utterances from stuttering and normally speaking children, aged two through four years, were analyzed by clinicians specializing in stuttering, general clinicians, and university students (total n=25). Results indicated that the validity of the data language used by researchers to describe stuttered and normal speech in early childhood may be…

Four experiments on the acquisition of binding are compared, two conducted with Italian-speaking children and two with English-speaking children. English-speaking children's mastery of pronominal binding is found to lag behind their mastery of binding for anaphors and R-expressions. (61 references) (Author/LB)
