Twelve 21/2-year-old children received adult verbal intervention selectively directed toward acquisition of either question forms or verb forms. Findings showed that children who received verb intervention acquired new verb structures while children who received question intervention acquired new forms of questions. (Author/JMB)

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)

Discusses a longitudinal study of young children's acquisition of complex sentences for expressing their beliefs about causally related events, in the transition in language development from simple to complex syntax. While most of the children's statements expressed subjective meaning overall, the acquisition of syntactic connectives was…

Five language-eliciting situations were presented to kindergarten and primary-grade children to identify developmental trends and task effects in the complexity of language structures, vocabulary, functions, and story conventions used. Limited developmental differences and significant task effects were found. Implications for classroom instruction…

Ostensive definitions of words are ambiguities as to their referent. In a study of infant-mother dyads engaged in looking at picture books, 95 percent of ostensive definitions referred to the whole object depicted rather than parts, attributes, or actions. When parts were named, ambiguity was avoided by naming the part and the whole. (PJM)

A production-based method of investigating children's understanding of deictic verbs is described. Use of "come/go" and "bring/take" by 4-7-year-olds is compared with Clark and Garnica's 1974 study. Data reveal different facts about verb acquisition processes and order. (CHK)

Two experiments showed two-year-olds pairs of videotaped actions, one familiar and one novel, and asked them to select referents of novel verbs. For actions not involving objects, children tended to select the novel action over the familiar one in each of four experiments. For actions involving objects, novel actions were chosen more often than…

Examined relationships among word comprehension, word production, and enactive and gestural naming by 136 infants of 12-16 months. Results indicate that infants can use adult speech as an aid in the reproduction of modeled gestures. (RJC)

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.)

This study of 2.5 and 3.5 year olds indicated that children of this age do not know many names for solid substances but can be taught names for them; that children represent the names as mass nouns and possibly adjectives; and that there is development of children's nonlinguistic knowledge of substances between the ages of 2.5 and 3 years. (TJQ)

Communication samples were collected from 15 normally developing children (ages 11-27 months) during the prelinguistic, single-word, and multiword stages, using both structured and unstructured contexts. Significantly more requests were used during the structured context, but no significant difference was found between the numbers of comments used…

Children identified as late talkers at 20-34 months of age were followed yearly throughout the preschool period. Data suggest that the longer a language delay persists, the less the chance of spontaneous recovery during the preschool period. Late-talking girls had less chance for spontaneous recovery than did late-talking boys. (Author/JDD)

Two experiments used the preferential looking task to assess early word comprehension in 12- to 24-month olds. Results indicated that when target stimuli were named, 12-month olds displayed an increase in target looking for typical--but not atypical--targets, whereas 18- and 24-month olds displayed increases for both. (Author/KB)

Uses a quasi-experimental design to compare the social adjustment of 21 children who received the Language for Learning program with those of 24 children enrolled in a comparison school. Finds that the Language for Learning program produced statistically and educationally significant effects, including improvements in social skills and reductions…
