Background: This study reports the language and memory progress over five years of 30 adolescents and young adults with Down syndrome, and investigates the relationship of earlier phonological memory abilities to later language development. Methods: Tests of nonverbal ability, receptive vocabulary, grammar comprehension, digit span and nonword…

The assessment of hearing impaired children is fraught with a number of problems. These include lack of valid assessment measures, faulty theoretical assumptions, lack of knowledge regarding the functioning of cognitive processes of these children, and biases against these children. This article briefly considers these issues and describes a study…

The current research compared two accounts of the relation between language and false belief in children, namely that (a) language is generally related to false belief because both require secondary representation in a social-interactional context and that (b) specific language structures that explicitly code meta representation contribute…

The literature describing deaf persons' intelligence was subjected to a quantitative and qualitative review in this analysis of 85 studies containing independent samples of 43,177 deaf subjects. First, bibliometric analyses were conducted to define the scope, dissemination, and trajectory of the research investigating deafness and Intelligence…

Differences in 3-month-old infants' vocal responsiveness to vocal-visual stimulation by mothers and strangers has been shown to be related to performance on both the Stanford-Binet at 3 years of age and the Illinois Test of Psycholinguistics at 5 years of age. The present retesting of 12 of the original 14 normal, first-born male subjects, now 12…

Four males and four females from each of grades one through six served as subjects in an investigation of the development of recursive thought (imagining other people's thoughts). One half of the subjects were asked to tell what a little boy in a picture was thinking about various configurations of faces. The remaining subjects were told the…

This study examined the relationships between spatial ability, mathematics achievement, and sex for students in grades 2-7. Four spatial tests (embedded figures, serial integration, coordination of viewpoints, and rotation and development of surfaces) were used to measure spatial ability; sex and mathematics achievement, as measured by the Iowa…

This training package in nonverbal communication and the affective domain rests on the rationale that nonverbal communication is a support system for the verbal message that we convey and that it can be divided into two channels--the vocal and the kinetic. The vocal channel consists of the pitch of the voice, and the kinetic consists of postures,…

While sequencing of speaking turns occurs in both adult and child systems, the adult system is elaborated by nonverbal signaling of speaker/listener roles and is constrained by expectations of speaking turns responsive to a shared topic. Children's speaking turns are not accompanied regularly by nonverbal signals; the speaker role does not require…

Seven studies were conducted to investigate the interactions between imagery-ability and experimental treatments that parallel instructional procedures. The general orientation of the studies was to extend the concepts of imaginal and verbal coding systems to include individual differences in symbolic habits. Thus all the studies took into account…

Various aspects of nonverbal communication are discussed in this paper, and the questions of how and why to teach it are considered. It is suggested that the nonverbal field can be roughly divided into three domains, in terms of method and the nature of the questions asked. Albert Scheflen and several other "nonverbal structuralists" are…

The time taken to name 56 drawings of objects on five separate occasions were analyzed for 21 ESN(M) children (i.e., moderately educationally subnormal) and 21 ESN(S) children (i.e., severely educationally subnormal), matched for picture-naming vocabulary. Results were discussed in terms of the Oldfield (1964) and Lachman (1973) models of lexical…

Moderate correlations were observed between the grade point average and nonverbal battery IQ scores of the Lorge Thorndike Intelligence Test administered to 27 elementary school students representing 12 countries during their first semester at a private American school overseas. Reasons are cited for additional research needs in the United States…
