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…

Examines phonetic variation in multisyllable babbling of infants from 7 to 11 months of age. The investigation was to verify assumptions that, in infant vocal development, there is a systematic increase in the phonetic variation of these babbles, and separate stages of repetitive and nonrepetitive babbling are posited.

The spelling of words in English is governed in part by the morphemes that make them up. This study examines the strength of children's knowledge of the role of root morphemes in spelling, specifically focusing on whether it can withstand interference by phonological changes. A total of 75 children between seven and nine years of age were given…

Describes a study designed to explore the nature of early use of two forms of the perfect--the present perfect and the present perfect progressive--by children over three years old. Three factors were found to influence children's selective imitation and paraphrasing of the perfect: verb form, semantic sense of the perfect, and duration of the…

Describes a study that tried to answer the following: (1) Are the passives of all actional verbs equally easy to understand? (2) Are the passives of all experiential verbs in a child's vocabulary about equally hard to understand? (3) Does comprehension of passives differ from verb to verb in a category? (SED)

Describes a study designed to discover how children approach the mass-count distinction as it applies to the use of "much" and "many." Results indicate that children do not approach the co-occurrence conditions of "much" and "many" with various nouns from a semantic point of view, but rather from a…

Describes a study of four- to five-year-old children's interpretations of statements involving "know" (savoir) and "think" (croire). The study tried to ascertain the language operations that modify a proposition or a basic assertion and to show the speaker's attitude towards the event asserted in the statement. (SED)

Verbal and nonverbal components of pointing initiation by Down's Syndrome children when looking at books were studied. Analysis of initiation patterns and point duration revealed possible developmental progression from a stage where point and exchange duration are linked to a stage where pointing becomes more detached from the exchange. (21…

Presents a simple scheme, based on formal categories, for coding stylistic variation in the early lexicon. When applied to the first 50 and 100 words of 12 children between 0;11 and 2;3, the major dimensions of difference are found to be the relative proportion of common nouns and the relative proportion of frozen phrases.

Experiments with groups of 30 children (aged 3 through 6) and 32 children (aged 5 through 8) showed that (1) children use linguistic form-class information with familiar discrete objects, (2) children do not use linguistic form-class information with familiar food, and (3) children use only object category information with unfamiliar items.…

Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Describes a study that investigates the order of acquisition of case-marked pronouns in Hebrew among 105 children between two and five years of age. Results indicate that children begin using case-marked pronouns as early as age two and that the stage of morphological development parallels that of English-speaking children. (SED)

In a study of early functions of negation (rejection and denial), 48 children under age 3 were asked easy yes/no questions. The most likely age range for the appearance of error-free denial "no" at 1 year/8 months to 2 years/1 month supports the continuity theory of negation development. (Contains 27 references.)

Describes a study that examines the effect of an adult-child discourse structure on the word combination produced by 17 children at the single-word utterance level. There was a significant difference between pretest and posttest multiword production for the experimental group of six children, but no difference for the control group. (SED)

Describes a study of 40 monolingual Spanish-speaking Peruvian children in which comprehension of six locative phrases was tested. Results are analyzed in terms of developmental sequence, locative acquisition, the effects of intrinsic label on projective locative comprehension, the effects of linguistic form, and the effects of context.
