The purpose of this article is to discuss definitional and measurement issues as well as empirical evidence regarding temperament, especially with regard to children's (a)typical speech and language development. Although all ages are considered, there is a predominant focus on children. Evidence from considerable empirical research lends support…

A review of research on brain imaging of developmental stuttering concludes that findings increasingly point to a failure of normal temporal lobe activation during speech that may either contribute to (or is the result of) a breakdown in the sequencing of processing among premotor regions implicated in phonologic planning.

Structural play-language relationships and diversity of symbolic play skills were compared with five language impaired and five nonimpaired children (ages 27-39 months). Findings indicated differences in mean length of utterance, mean length of sequence, and quantitative and qualitative aspects of symbolic play. (Author/DB)

Types of utterances (with locative action utterances specifically differentiated) were evaluated in a language-impaired child tracked between one year, six months and three years of age. Comparison with utterances in other children suggests the importance of such a fine-grained analysis in detecting semantic properties of child language…

This article suggests a possible link between incipient stuttering and early difficulty in language formulation. The hypothesis offers a unifying explanation of an array of empirical observations. Among these observations are the following: early stuttering occurs only on the first word of a syntactic structure; stuttering does not appear to be…

Reviews research indicating linguistic knowledge is not innate, that the infant brain is highly differentiated at birth, that processing biases that lead to the "standard brain plan" are innate and localized but not specific to language, and that the infant brain is highly plastic, permitting alternative "brain plans." (Author/CR)

Because all children with autism are deficient in joint attentional skills (ability to direct and maintain shared attention with another individual), this article reviews the literature on joint attention, its relationship other language rule systems, and its development in typical children. A case study illustrates the developmental course of…

Results show that comprehension of word types (nouns, verbs, etc.) and linguistic structure can be orderly, producing a hierarchy of complexity similar to that found in normally hearing children. However, performance was about three years behind that of normally hearing peers. Journal availability: Elsevier North Holland, Inc., 52 Vanderbilt…

A study found 36 children (ages 3-5) with specific language impairment (SLI) produced more errors with third person singular pronouns than did age-level peers, but did not make more errors than peers matched for mean length of utterance. Error patterns were similar in children with SLI and their language-level peers. (Contains references.)…

This article discusses current developments in connectionist modeling and the extension of principles of dynamical systems theory to cognitive and language development that have resulted in a new theory of language development known as emergentism. Specific language impairment is discussed within this emergentist view and preliminary implications…

The language transcripts of seven children with Down syndrome (DS) and seven typically developing children with comparable mean length of utterance levels were compared for verb argument structure. Findings suggest that syntactic difficulties may delay children with DS in overcoming the optional subject phenomena and the lesser number of anomalous…

The study investigated the effectiveness of a pragmatic language function protocol with a sample of 240 normal preschool children, aged 2-5, in a structured setting. The protocol was shown to be used reliably and was sensitive to differences in the mastery of language skills of normal children of different ages. (Author/JDD)

This study examined stimulability in 30 children (ages 3 to 5) with articulation impairments. Factors found to relate to stimulability were articulation visibility, the child's age, the family's socioeconomic status, and the child's overall imitative ability. Perception, severity, otitis media history, language abilities, consistency of…

Examines three alternatives to the classical framework of early cognitive development: modularity-nativism, connectionism, and theory-theory. Arguments are marshaled to support the "theory-theory" view, which emphasizes a combination of innate structure and qualitative reorganization in children's thought based on input from the people and things…

Phonological development of 145 children between the ages of 2 and 8 years was examined through annual assessment using a standardized articulation test. Process usage declined between 2 1/2 and 4 years and infrequent process usage was observed after the age of 4. Race differences were found, but no sex differences were found. (Author/PB)
