Analysis of 24 spontaneous speech samples from children at 24 and 30 months revealed a correlated progression in the form, function, and meaning of adjective modifiers used with increased language development. (Author/DEP)

Spontaneous full passives and related constructions from 234 children, aged 2 to 13, and elicited passives from 262 college students were analyzed. The agentive non-reversible did not appear until after age 9; and until age 11 no child produced both reversible and non-reversible passives. (Author/SW)

This study aimed to determine the average ages at which children imitate, produce and comprehend passive constructions. Previous findings that imitation precedes comprehension, which precedes production, are confirmed in this study for children aged 3-8. (CHK)

A study was undertaken to test the theory that canonical sentence schemas can sometimes assign argument structure to verbs. The theory has the advantage of explaining errors without postulating the acquisition of erroneous lexical entries that have to be learned, and it can be extended to other kinds of errors in the choice and placement of…

To determine the normal sequence of the development of Spanish phonology and Spanish grammatical patterns in the speech of native Spanish speakers, ages 2-5, a study of the acquisition of interrogative formation was undertaken. Two male and two females from each of nine age intervals between two and five were selected as informants; all were…

In order to test the hypothesis that the ability to form verbal concepts would increase with age, a test for verbal concept formation was developed and administered to 668 children between the ages of 4 and 9. By varying sentences that describe nonsense figures, 4 variables were systematically explored. (MS)

In a previous paper, J. Hurford accounts for errors in children's question forms by postulating that children incorrectly internalize adult rules. This article suggests that this rule is inconsistent and unjestified, and that such errors are due to segmentation problems and processing limitations. (CHK)

This article criticizes a previous paper that stressed a transformational analysis of children's question acquisition. It is argued that a surface structure generalization analysis makes empirically correct predictions about mistakes both in acquisition of inverted word order and in the form of "wh" questions. (CHK)

This document reports on three years of clinical research involving the development of effective clinical intervention procedures for children with slow language development. The assessment and treatment approaches discussed in the report are based upon the developmental model of grammar described in Developmental Sentence Analysis (DSA), a…

Comprehension of the quantifiers "some" and "all" was studied with 202 children, three to nine years old. Thirty-two quantifier sentences dealing with descriptions of circles and squares were presented to the children. Wooden objects were presented to some children to see if results were affected by the choice of abstract objects, but no…

The research reported is part of an investigation into the acquisition of grammar, using nonlinguistic information from situational and behavioral context to analyze the development of linguistic expression. Three children were seen for approximately 8 hours, every 6 weeks, in their homes, from the age of 19 months--soon after the earliest…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

Universal trends and individual variations in the language development process of the child are described and their relationships to beginning reading instruction are discussed. Child language begins with single word utterances to name things or to express needs and feelings. With a two-word utterance, the child can describe relationships more…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…
