Reports on a study of three children's single-word responses to parents' questions, focusing on the interrelations between children's ability to answer questions, the types of semantic content used in appropriate and inappropriate answers, and questions asked by the parents. (Author/AM)

Examines how children's beliefs about word meanings may affect their use of contrastive linguistic information in the input of word learning. Two separate studies are discussed that involve how three- and four-year-old children handled new word meanings after exposure to novel terms. (58 references) (GLR)

Argues that current attempts to show that forward directionality effects can also be induced in Japanese acquisition do not succeed in supporting the forward directionality preference of anaphora. (57 references) (Author/CB)

Argues that the measures of content and style of maternal talk used by the Murray and Trevarthen (1986) study of temporal patterning during vocal engagements did not directly indicate the ways in which the behaviors of the partners (mothers and infants) were combined on a moment-to-moment basis. (Author/CB)

Results of three investigations of the development of word definitions indicated that younger childrens' definitions, including use or lack of use of superordinate categorical terms, fell short of adult informativeness, while, by age 10, children generally met such criteria in their definitions.

When children produce regularizations like "comed," not all verbs are equally liked to be regularized. It is argued that one predictor is which vowels are present in the base form vs. the past tense form, and that regularizations are likely when the base vowel is dominant and unlikely when the past tense vowel is dominant. (Contains 25…

The study analyzes four- to eight-year-old French children's acquisition of conditional verb forms. Relevant data in the literature and results of an experiment designed to gain information on the temporal meaning of young children's past conditional verb forms are presented and discussed.

An infant girl's unusual phonological behavior was evaluated in light of a maternal model which appeared to exaggerate features of normal conversational speech. Parental responses to immature speech patterns may account for selected case study behaviors which have been reported in both the child phonology and child fluency literatures. (KM)

Describes the Human Communication Research Centre Dialogue Database. The database consists of over 700 transcribed and coded dialogues from pairs of speakers aged from 7-14. The speakers are recorded over 2 years while tackling cooperative problem-solving tasks, and the same pairs of speakers are recorded over 2 years tackling 10 different…

Two experiments investigated the factors that govern children's use of singular and plural forms of count nouns. Experiment 1 used an elicited production task to investigate whether children use referential and/or syntactic information to determine the form of the count nouns when the two sources of information conflict (e.g. "each x, one of the…

Two nonce-word studies examined German-speaking children's productivity with the "Perfekt" (present perfect) from 2;6 to 3;6. The German "Perfekt" consists of the past participle of the main verb and an inflected form of an auxiliary (either "haben" "have" or "sein" "be"). In Study 1, nonce verbs were either introduced in the infinitival form, and…

There has been relatively little discussion in the field of child language acquisition about how best to sample from children's spontaneous speech, particularly with regard to quantitative issues. Here we provide quantitative information designed to help researchers make decisions about how best to sample children's speech for particular research…

The purpose of this research was to show how the syntactic and semantic components of the tense-aspect system interact during the acquisition process. Our methodology involved: (1) identifying predicates, (2) finding the initial occurrence of their tense-aspect morphology, and (3) observing the emergence of contrasts. Six children learning Polish…

Overgeneralization occurs when a child uses the wrong word to name an object and is often observed in the early stages of word learning. We develop a method to elicit overgeneralizations in the laboratory by priming children to say the names of objects perceptually similar to known and unknown target objects. Experiment 1 examined 18 two-year-old…

This paper presents a model of syntax acquisition, whose main points are as follows: Syntax is acquired in an item-based manner; early learning facilitates subsequent learning--as evidenced by the accelerating rate of new verbs entering a given structure; and mastery of syntactic knowledge is typically achieved through practice--as evidenced by…
