Compares performance and verbal IQ scores of 38 normal and 34 specifically language-delayed children ages 5 to 8 1/2 years. Results do not support the hypothesis that language delay in children is related to a nonverbal cognitive deficit. (Author/RH)

The relationship between children's language acquisition and their nonverbal intelligence has a long tradition of scientific inquiry. Current attention focuses on the use of nonverbal IQ level as an exclusionary criterion in the definition of specific language impairment (SLI). Grammatical tense deficits are known as a clinical marker of SLI, but…

The relationship between nonverbal intelligence and English language ability was examined in 25 deaf children between the ages of 6 and 10. Subtests which require visual memory consistently entered the multiple regression equations as the best predictors of language performance. (Author)

Investigated whether sustained forms of nonverbal coordinated action facilitates toddlers' generation of verbal discourse with one another. Twenty-four 2-year-olds interacted with an adult, in 2 nonverbal interactive contexts: an imitation game and parallel play. Found that involvement in nonverbal imitation games facilitated toddlers responding…

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 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…

A nonverbal paradigm for assessing conservation based on an operant discrimination learning procedure is described. Initial results suggest that young children who could not conserve within the traditional verbal procedure were more likely to demonstrate conservation within the nonverbal paradigm and that traditional Piagetian tasks are verbally…

Language development was studied in 310 pairs of 4-year-old twins. Rotated factor analyses indicated presence of a general language factor (L) and a general nonverbal factor (NV). Moderate genetic influence was found for L and NV abilities. Bivariate genetic analysis estimated a genetic correlation of .63 between L and NV abilities. Results…

This study investigates the oral language skills of 8-year-old children with impaired reading comprehension. Despite fluent and accurate reading and normal nonverbal ability, these children are poor at understanding what they have read. Tasks tapping 3 domains of oral language, namely phonology, semantics, and morphosyntax, were administered,…

In two experiments, infants 9-17 months of age were probed for recognition of a previously unfamiliar trained name. Responses were videotaped and scored for gaze, gesture, and vocalization. Results demonstrate improvement in receptive language capacity over the age range studied. (RMH)

Three studies examined theory-of-mind concepts among children ages 6-13 years with deafness or autism, and 4-year-olds with normal development. Findings indicated that while the children with deafness or autism scored significantly lower on standard tests of false belief understanding, they scored higher on even the most challenging drawing-based…

This study addressed the extent to which performance on selected verbal and nonverbal measures contributed to the prediction of inflection learning with 20 normal boys (ages 4 to 5). Results suggested that inflection learning may be tied more to other language abilities than to nonverbal cognitive skills in normally developing boys. (DB)
