Reports on an investigation of the surface forms used by mothers to direct their children's behavior, and of the ways in which these forms are modified as the children grow older and their comprehension of indirect speech acts increases. (AM)

The acquisition and use of locative prepositions by 30 Hebrew-speaking children aged two to three years was investigated in a cross-sectional study. Both the order of acquisition and the role of linguistic complexity in determining that order were examined. (Author/AM)

Preschool children aged 2.6 to 5.0 were presented with reversible active and passive sentences in four comprehension test settings. The children's response patterns were analyzed in terms of individual response patterns. Extralinguistic cues accounted for the most common patterns. (Author/AM)

Brown's (1979) assertion that frequency of input is not a significant variable in language acquisition was evaluated through a reanalysis of Brown's data. Frequency of parental speech input was found to be highly related to frequency of production. (Author/AM)

This study aimed to determine the average ages at which children imitate, produce and comprehend passive constructions. Previous findings that imitation precedes comprehension, which precedes production, are confirmed in this study for children aged 3-8. (CHK)

This review analyzes research on acquisition of Hungarian morphology and syntax, specifically, morphological analysis, neologisms, acquisition of first inflections, morpheme order, word order and agreement. Because of Hungarian structure, errors in segmentation of the utterance and the word are minimized. Morphological analysis begins at semantic…

Examines speech samples of a boy 2;4 to 2;11 to determine the relationship between speech disturbances and language production process development. Disfluencies were randomly distributed during the first half of the observation period, then concentrated in function words and sentence initial words, reflecting an emerging speech component dedicated…

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

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…

Presents a quantitative study of children's noun plural overregularizations on recent comparisons of connectionist and symbolic models of language. The speech of 10 English-speaking children aged 1;3 to 5;2 were analyzed. Results pose challenges to connectionist models, but are consistent with the blocking-and-retrieval-failure model in which…

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 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)

Provides a brief history of the empiricism-nativism issue, considering present-day intellectual roots of nativist and empiricist inclinations. A schema is proposed for explaining the ontogenetic origin of an innate attribute or principle relevant to language. An attempt is made to explain the origin of primitives as derived by learning. (Contains…

An experimental study examined the comprehension of sentences containing concessive connectives, considered from an argumentative-conclusive point of view, in 8- to 10-year-old French children (n=24). Two tasks were used: (1) subjects had to choose between opposite preceding contexts of sentences and (2) conclusions that could be drawn from the…
