A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

A study compared learning disabled (LD) adolescents with oral expressive problems to non-learning-disabled (NLD) adolescents on a formal operations task, with emphasis on a comparison between non-verbal performance and verbal explanations of the task. This paper reports part of the study, a comparison of two high school freshman subjects. The task…

This study explores children's development of dual-level phonological processing posited by generative theory for adult language users. Evidence suggesting 6-year-olds' utilization of morphophonemic segments was obtained by asking children to imitate complex words, omit specified portions, and discuss the meaning of the resulting word-parts. The…

The purpose of this paper is to familiarize readers with Vygotsky's theory on verbal regulation of thinking skills, to describe related research and applications of the theory, and to explore its relevance for researchers, parents, and educators. (MT)

Discusses three experiments investigating the development of word-by-word comprehension in 5-, 7-, and 10-year olds. Subjects monitored for target words in a sentence. Variable included types of monitoring tasks and distribution and context of target words. Results are discussed in terms of the types of comprehension processes various tasks…

Examines speech samples of a boy 2;4 to 2;11 to determine the relationship between speech disturbances and language production process development. Disfluencies were randomly distributed during the first half of the observation period, then concentrated in function words and sentence initial words, reflecting an emerging speech component dedicated…

How a child answers questions provides information about how he or she processes input. A child's early responses to questions at age one year, three months, were compared to her responses at one year, seven months, when she was in the two-word stage. (SW)

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…

Sound play is important to child language development in that it contributes to the phonetic substrate, it is a factor in phonological development, and it is something to be learned as part of the socially acceptable use of language. Sound play progresses in three stages: (1) babbling, in which a gradual acquisition of phonetic units is built up…

Focusing on language development--from beginning speech to literacy--with particular attention paid to growth in writing, this paper identifies and describes: (1) links between speech and writing; and (2) features of children's written and spoken texts that indicate growth. The process of constructing "texts" is presented as the fabric…

A study was conducted to test whether three, four, and five-year-old children would be better able to use either static or dynamic properties for grouping objects, and whether performance under these conditions would be better than when no property was given. One of the two study tasks, the free sort, also used by Rosch et al. (1976), asked…

A paper by Keenan and Klein (1975) provided evidence for the hypothesis that conversationality is present in children as young as 2 and 1/2 years of age. Results of the study indicated that before the emergence of more adult-like coherency operations, the children passed through a period in which such operations were foreshadowed by vocal play.…

This paper reports the results of a preliminary study dealing with the ways in which children between ages 6 and 7 organize spoken language. In particular, aspects of the temporal and segmental structure of polysyllabic English words containing the syllable C/jul/, as in the word "pediculous," are dealt with. This study is based on the assumption…

The crib talk reported here of a 2;2-2;4-year-old boy replicates the phenomenon of crib talk reported in previous studies by other investigators. This study adds a corpus of mother-child interaction (MCI) and tests one aspect of the hypothesis that crib talk may enhance production of linguistic forms at a later date. Transcripts of monologues were…

This paper reports on an experiment undertaken to delineate more clearly the relationship between the naming process in children and certain aspects of the environment which may play a role in that process. The investigation concerned the effect of manipulation and of object novelty on naming. Sixteen children, ten girls and six boys, ranging in…
