It has long been thought that the prefrontal cortex, as the seat of most higher brain functions, is functionally silent during most of infancy. This review highlights recent work concerned with the precise mapping (localization) of brain activation in human infants, providing evidence that prefrontal cortex exhibits functional activation much…

Background: A community-representative sample of screened and clinically examined children with language delay at 2.5 years of age was followed up at school age when their language development was again examined and the occurrence of neuropsychiatric/neurodevelopmental disorder (attention deficit/hyperactivity disorder (ADHD) and/or autism…

Examines the relationship between the quantity and type of spontaneous private speech and delayed match-to-sample performance among kindergarten children (N=65). (MP)

This report, covering the period from October 1 to January 31, 1975, is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The manuscripts in this report discuss such topics as the complexity of a motor theory of speech perception, a systems…

Examined whether speech rate is related to the amount recalled and if developmental increases in speech rate allow faster rehearsal with age, and hence, greater recall. Found that the group relationship was clear and replicable but that speech rates of individual children were not good predictors of those children's memory spans; age was found to…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. "Preliminaries to a Theory of Action with Reference to Vision" attempts to describe how the contents of vision may relate to the process of action. "On the Relationship of Speech…

Examines short-term memory for spoken words ignored at the time of their presentation. Age differences in the persistence of memory was found. Suggests that relatively attention-free properties of short-term memory may change with development in childhood, and priority should be given to distinguish maturational and experiential influences on…

In response to Sawyer (EC 602 748), this article provides evidence from cognitive neuropsychological case reports that does not support the strong metalinguistic hypothesis, which contends that explicit, conscious mastery of the relationship between phonology and orthography is a necessary (and perhaps sufficient) precondition for the development…

Four scales developed by Marion Monroe for recording, describing, analyzing, and rating children's oral language skills are described and presented in this paper. The skills assessed by the scales are first described as follows: (1) how a child thinks, as revealed by the quality of ideas; (2) how a child thinks, as revealed by definition of words;…

Examines characteristics of the mental processes required for writing, compares and contrasts the nature of processing required for other cognitive activities, and reviews recent research on children's writing that reveals the advantages as well as disadvantages of superimposing writing skills over well-developed language skills. (HOD)

A study examined patterns of development in spoken interaction and types of causal thought that might reflect the human capacity to displace, that is, to shift reference from the present moment to another moment in time. Participants were four infants and their parents, who came to a laboratory for one-half hour every 2 weeks from the child's…

Describes the development and evaluation of a communication program which, through speaker-listener settings, aims to give children strategies for recognizing and conveying critical attributes, ignoring redundant information, and sequencing information. (Author/BW)

A study examined the development of discourse cohesion in first language acquisition within a functional and cross-linguistic perspective. The analyses focused on how children introduce new referents in discourse across four languages: English, French, German, and Mandarin Chinese. The data base consists of narratives produced by children between…

This paper explores the relation between the communicative and categorical functions of language and the acquisition of language production. Three major factors in language acquisition are communication, ability for representation and the process of categorization. This paper offers evidence that a sudden and dramatic increase in lexical skill…

The study examined the relation of language use and logical thought to social experience with both age and class held constant. The primary assumptions under study were: that the logic of symbolic grouping was highly sensitive to a child's experience with the objects to which that logic was applied; that the existence of diglossia in a bilingual…
