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)

Describes a study that compared the language abilities of first and third grade children. The children's narratives were analyzed for differences in T-units and the use of reference and conjoining. Results indicate that the older children used longer T-units and generally had more cohesive ties within their narratives. (Author/SED)

Preliminary version of this article presented at the meetings of the Society for Research in Child Development, Minneapolis, Minnesota, April 1971. Research and preparation of the paper supported in part by an Intramural Grant from the Regents of the University of California to T. Kenney. (VM)

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…

This paper, one in a series investigating day care services, is based on two assumptions concerning verbalizations of preschool children: (1) the complexity of verbalizations is more important than the quantity; and (2) the quality of care is directly related to the occurrence of the complexity of verbalizations. The higher the occurrence of…

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…

A linguistic analysis of five children's books, randomly selected from the "Modern Masters Books for Children" series, described the features of language found in books for beginning readers and demonstrated the value of structural analysis in reading research. Four linguistic measures were applied to each book: 1) the average number of words in a…
