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)

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…

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…

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…

Two major strategies for linguistically encoding an idea or proposition are suggested. The first strategy involves encoding an idea in the space of a single utterance, while the second strategy conveys the proposition through a sequence of two or more utterances. The tendency has been to focus on discourse as a composite of sentences (the first…

The acquisition of rules for formulating causative verbs was studied with children over a period of a few years. Most of the data is based on the spontaneous speech of the author's two daughters, from age 2;6 to 6;2 and from age 2;4 to 3;11. It was hypothesized that there are at least two prerequisites for the child's formulation of a general rule…

This paper discusses Lee and Canter's procedure for assessing child language development as an example of how psycholinguistics is beginning to enter the language clinic. The procedure includes recording and transcribing examples of children's sentences, then scoring them to yield a Developmental Sentence Score (DDS). This procedure was compared…

A study of overregularized use of verbs by two children over a period when they were 2 1/2 to 5 years of age shows overregularizations in two directions: non-causative verbs were used as causatives; and causative verbs were used non-causatively. According to terminology from logic, predicates were classified according to the number of noun-phrase…

This is a longitudinal study of a child's acquisition of Mandarin phonology between the ages of 1;2 and 2;8. During this period, the child was much less verbal than many children reported in other child phonology studies. The study consists of two parts. The first part is a description of the child's "proto-language," in which he used…

This investigation studied the development of the form and function of negative sentences, and how it relates to the input on negation that children receive from their parents. The data came from three children: two from a previous study (Bellugi) and one the son of the investigators. A detailed analysis was carried out of the syntactic form and…

This study considers the interaction of syntactic and pragmatic factors (social and cognitive) in children's production of coordinate structures involving conjunction reduction. Two aspects of pragmatic context were considered: (1) the pattern of uncertainty or redundancy in a complex action sequence, and (2) the perceptual grouping of objects…

The ability of children at different ages to distinguish instructions to "ask" from instructions to "tell" and the types of structures used to express these directives were studied. Subjects were 120 children, aged 2 years 6 months to 6 years 6 months. Children were instructed to either ask or tell an adult or another child to give them puzzle…
