A study of data on Japanese children shows that the development of verbs occurs at the same time as the development of nouns and may even precede it. The subjects for the study were two children who were learning Japanese as their first language. Four speech samples, taken between the ages of 22 and 28 months, were audiotaped and supplemented by…

The spontaneous speech of a Mohawk-speaking boy was recorded from age 2;10 to 4;1. Analysis of this speech indicated that certain verbal prefixes are acquired earlier than suffixes. The pronominal prefix of nouns, on the other hand, enters late. Yet, before the appearance of any nominal affix, the child already uses a pronominal possessive as a…

This paper is a technical report of analyses carried out to determine the effects of parents' involvement in a prekindergarten program on their children's cognitive development. The research was part of a longitudinal study of the New York State Experimental Prekindergarten Program. A multiple linear regression approach was used to test hypotheses…

As part of a longitudinal study of the New York State Experimental Prekindergarten Program, the effect of degree of parental involvement in the program on children's cognitive development was examined. Parent involvement included employment in the program, school visits, home visits by school personnel, group meetings, and incidental contacts such…

The verbal behavior of three children was sampled. The samples were analyzed to obtain a picture of three stages of the children's language development, specifically the interrogative structures. Each stage was about 4- or 5-months long, starting at the 18th to 28th month, depending upon the child's level of linguistic ability. The interrogative…

A study was conducted to determine whether the child expresses linguistic knowledge during the single-word period. The order of mention in 65 sets of successive single-word utterances from five children at Stage 1, two to four years old, were analyzed. To elicit speech, the children were shown line drawings representing such situations as animate…

This study investigated the relationships obtained among verbal imitation, comprehension, and production when a stimulus sentence exceeded the child's short term memory. A total of 32 children, aged 3 to 5 years, took tests of comprehension, nonverbal imitation, verbal imitation, and production of structures expressing sequence ("before", "after",…

Two experiments related to the development of verbal self-control in children were conducted. In the first experiment, 36 adults and 36 four year olds were administered a vocal alone, a motor alone, and a combined-reaction-time task. In the second experiment, 54 kindergarten subjects and 60 fifth-grade subjects were each administered a double…

To study maternal behaviors as related to social class differences, 30 middle class and 30 working class white mothers were observed at home on two separate days with their 10-month-old firstborn baby girls. Predesignated behaviors which occurred during 5-second intervals were recorded by an observer. Total observation time was 4 hours for each…

In this report, an analysis is made of the Title 1 project of the Lorain City Schools in Northern Ohio. The language growth of an experimental group of 30 disadvantaged first graders, who had spent 45 minutes each day in a special language experience classroom, was analyzed using oral language recordings and extensive language tests in order to…

Speech research suggests why phoneme segmentation is more difficult than syllable segmentation. This study provides direct evidence of a developmental ordering of syllable and phoneme segmentation abilities in the young child. By means of a task which required preschool, kindergarten, and first grade children to tap out the number of segments in…

An examination of mean scores for two samples of 884 and 1570 high school students who were administered the National Merit Scholarship Qualification Test (NMSQT) in 1962 and for the entire population of 794,589 students given the same test in 1965 revealed consistent effects of birth order on mean score. Earlyborn, and firstborn in particular,…

Verbal responses of 50 college freshmen were compared to determine whether any differences existed between the types of responses given by students listed as high or low in verbal ability according to the Scholastic Aptitude Test (SAT). The students, from two colleges, were tested individually using an experimenter-devised language inventory which…

This study investigated the effects of a program of mother-child interaction using children's books on the verbal skills of culturally disadvantaged 3-year-olds. A total of 47 subjects were involved in the study, with white and black children, males and females equally represented in experimental, placebo and control groups. After only three…
