This article compares children's productions of wh-questions such as "who?" or "what?". Data were gathered using the technique of elicited production. (26 references) (JL)

Relative importance of appearance and potential function in children's object naming was examined. First, 16 children, taught novel names for unfamiliar objects, had to decide whether these applied to items that resembled the training objects in appearance or potential function. Then the name training procedure was revised so that equal emphasis…

Two studies of the unintelligible speech of developmentally delayed children found that more intelligible child speech was found in routine than in nonroutine situations and that extracted utterances were more intelligible under context-information-present conditions. (35 references) (Author/CB)

Presents four principles for archive-based language research: maximum readability and minimum bias; consistent encoding for exhaustive computer search; systematic contrastiveness; and data comparability in elicitation, transcription and coding. Examples from existing computer archives illustrate these and other principles, and strategies are…

Interaction between lexical acquisition and acquisition of initial voiceless stops (VSs) was studied in two normally developing children by acoustically examining token-by-token accuracy of initial VS targets in different lexical items. Tokens representing the emergence of accurate VS production were restricted to certain words, largely old words…

Tested the prediction that "yes-no" questions that place forms of the copula "be" in initial position will also increase the rate of growth of children's copula verb development. Data from 33 children who were matched for stage of language development at 1;9 and 2;0 confirm that the frequency of inverted copulas in yes-no…

Different interactions of two common phenomena--final consonant omission and vowel lengthening before voiced consonants--are examined with a focus on a case study of two young children with phonological delays in their acquisition of English. Argues that at least some developmental opacity effects support sympathy and that such effects emerge in…

Examined use of word order and animacy for interpretation of sentences by typically-developing and language delayed children. Results indicate that typically-developing 2-year-olds use neither cue consistently to interpret sentences; typically-developing 2.5-year-olds used a coalition of word order and animacy cues; and language-delayed…

Investigated whether infants can construe the same set of objects as an object category or as embodying an object property. Results of 2 experiments involving 48 and 64 14-month-olds respectively suggest that infants have begun to distinguish nouns from adjectives, they expect different grammatical forms to highlight different aspects, and that…

Two experiments investigated why preschool children sometimes produce multiple words of a referent, but other times allow only on word. In the first experiment, 3- and 4-year-old children completed a naming task. Children produced on average more than two words per object. In the second, 3- and 4-year-olds learned new words for nameable objects.…

Discusses syntactic optionality, the coexistence within an individual grammar of two or more variants of a given construction that make use of the same lexical resources and express the same meaning. Focus is on syntactic optionality in second language grammars. (Author/VWL)

Examined input frequency, sentence position, and duration as contributing factors to grammatical inflections. In parents' conversations with and stories aimed at young children, noun plural inflections were more frequent than third singular verb inflections, especially in sentence-final position. Analysis of four mothers' speech when reading…

Investigated young children's learning of the correct use of first and second person pronouns, using feed-forward neural networks. The study involved four computer simulations using the cascade-correlation (CC) learning algorithm. Results indicated that the CC networks could produce the correct pronouns without errors if children heard pronouns…

Investigated young blind children's use of pronouns, following blind and sighted children longitudinally and analyzing every spatial deictic term and personal reference term they used (noting reversal errors). Results indicated that blind children began to use personal reference terms as early as sighted children, and use of reversals was not…

In a series of production and grammaticality judgment experiments, I investigated the status of children's non-adult questions with 2 auxiliary verbs, such as "What did the smurf didn't buy." Previous studies showed that these questions were produced primarily in negative contexts. In the first part of the study, I tested whether children produce…
