The lexical variables of word frequency and neighborhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays participated in an alternating-treatments experiment to promote sound change. Results indicated word frequency was most facilitative in sound change, whereas dense…

Compared mother', fathers', and siblings' corrective repetitions to children's errors across different settings. Analyses revealed that mothers and fathers provided more corrective repetitions than did siblings. Results are discussed in terms of current negative evidence research. (Author/VWL)

Recent studies have suggested that cultures vary in subtle ways in the talk about talk that children hear and learn to produce. Twenty-two three-year-old children and their families in respectively Oslo, Norway and Cambridge, Massachusetts were observed during mealtime with the aim of identifying talk-focused talk. The analysis distinguished talk…

The ability to make clear reference in connected discourse was examined in children learning Cantonese, a Chinese language where noun phrase constituents, whatever their grammatical role, are omissible from sentences under discourse conditions that are not well-understood. Forty-three typically developing children aged 3;0, 5;0, 7;0 and 12;0 told…

Based on a study of 50 children between the ages of 3;0 and 5;6, the reasons for the differential difficulty of various forms of "who,""why,""when," and "how" questions are postulated. (EJS)

In this experiment, children were given three words (a triplet made up of two nouns and one verb) and were asked to produce an utterance with them. The results were analyzed in terms of word order chosen and age of child. (NCR)

In a study, Tagalog-speaking children, 3-, 5-, and 7-year olds, demonstrated better mastery of patient-focus (passive) than agent-focus (active) sentence structure. These results were attributed to the children's strategy of interpreting the first noun of a sentence to be the agent of the action. (SW)

An experiment on children aged 2 to 7 led to a critical evaluation of Piaget's implicit contention that young children use determiners anaphorically. It is suggested that the importance of young children's processing procedures on the linguistic environment has been underestimated in Piaget's interactive epistemology. (CHK)

Describes the presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system. Evidence suggests that this constant harmony constraint operated across morpheme boundaries, causing a delay in the onset of two-word utterances and influencing the selection of words that could occur in word…

The ability of children between the ages of two years and four years, eight months, to produce locative pre- or postpositions was investigated in English, Italian, Serbocroatian, and Turkish to discover universals of conceptual and communicative development. (Author/AM)

Evaluates competing proposals for the underspecification of phonological representations against the facts of phonemic acquisition. Results indicate that context-sensitive radical underspecification provides a plausible account of each developmental stage and the transition between stages with minimal grammar change.

Evaluates the principle of laryngeal-supralaryngeal cyclicity by manipulating the domain cycle and phase relationship of the cycle as independent variables and by monitoring longitudinally the order of emergent phonemic distinctions in the sound systems of seven children with phonological delays as the dependent variable. Findings are discussed.…

Presents data from 4 Inuit children ages 2;0 to 3;6 that shows relatively early acquisition of both simple and complex forms of the passive. Within this age range, children are productively producing truncated, full, action, and experiential passive. Reasons for this precociousness, including adult input and language structure, are explored. (56…

Naturalistic mother-child speech between autistic, Down's syndrome, or normal children and their mothers was studied to determine whether imitation facilitates grammar acquisition. Spontaneous utterances were longer and contained more advanced grammar than imitation utterances, indicating that imitation does not play a significant role in grammar…

Examined the development of Irish word order patterns. It was found that the 1.5- to 3-year-olds (N=3) studied used subject-initial utterances more frequently than adults in input, and that for both adults and children the elision of the verb "to be" had a significant role in the placement of subjects in the utterances. (42 references)…
