The present study investigated three-year-olds' sensitivity to direct and indirect cues to others' knowledge states for word learning purposes. Children were given either direct, physical cues to knowledge or indirect, verbal cues to knowledge. Preschoolers revealed a better ability to learn words from a speaker following direct, physical cues to…

The phonotactic development of one child is traced from age 3;9 to 5;3. Data are presented in a table indicating both the child's phonological equivalent of adult consonant sequences and the range distinguished by the child at a given stage. (CHK)

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)

Diary observations of two-year-olds' over-extended word use have been interpreted as arising from the word's underlying semantic feature structure. This interpretation was rejected after a study of five children. The need to construct models of early word meaning reflecting certain early language development patterns is discussed. (CHK)

The comprehension ability of 36 children at three stages of telegraphic speech was assessed using active behavioral responses to declarative and imperative sentences. A significant increase in verbal and behavioral appropriateness with age was found for imperative and declarative forms. Results are compared with Shipley, Smith and Gleitman's…

Interpersonal functions of everyday caretaker speech usage are examined when addressed to toddlers, threes and fours. Results support hypotheses derived from Piagetian theory concerning early developments in ego-differentiation. (Author/RM)

This paper reports data for voice onset time (VOT) for /d/ and /t/, from six children at average age 3;0. Values for /d/ clearly achieve the short voicing lag category of adults, reported previously. Values for /t/, however, are much more varied, although falling within the category long voicing lag. (CHK)

Verb forms used by 14 4-year-olds in their pretend play were investigated in a study of the use of past verb forms to express "unreality." Results suggest that different past verb forms co-occur with different play activities; e.g., present perfect occurring when children implement their plans and communicate within an already…

Command of transitivity permutations in Hebrew, where a change in verb-argument syntax entails a change in verb morphology, were examined in 30 children aged 2, 3, and 8. Findings have implications for the development of derivational morphology, item-based versus class-based learning, and the impact of lexical productivity and language-particular…

The speech children spontaneously quote was examined in 2 studies involving personal narratives from 96 children aged 4 to 9 and speech in 25 children aged 1 to 5. Findings showed that frequency of reported speech increased with age and direct quotation was more common than indirect or summarized quotations at all ages. (57 references) (Author/LB)
