A growing body of evidence demonstrates that individual differences in declarative memory may be an important predictor of second language (L2) abilities. However, the evidence comes from studies using different declarative memory tasks that vary in their reliance on verbal abilities and task demands, which preclude estimating the size of the…

Spatial language and ability play important roles in children's cognitive development. Spatial ability in kindergarten predicts achievement in reading, math, science, and technology in primary school and therefore constitutes an important skill set in preparation for school entrance. Good spatial thinking skills are required for learning in…

The Reynolds Intellectual Assessment Scales, Second Edition (RIAS-2; Reynolds & Kamphaus, 2015) is an intelligence test for those aged 3 to 94 years. It contains eight subtests designed to assess general intelligence, verbal and nonverbal intelligence, memory, and processing speed. The two subtests targeting processing speed are new to the…

Purpose: Developmental language disorder (DLD) is defined by persistent difficulties with language, but a growing body of evidence suggests that it is also associated with domain-general and nonverbal information-processing deficits. However, the interconnections between cognitive functions, both nonverbal and language related, are still unclear.…

Students from refugee background enter Australian schools to pursue their educational goal. Though most do well academically, a few encounter educational difficulties and struggle to acquire English language. An exploratory qualitative case study approach was used to investigate factors contributing to poor development of English language and…

Background: A population sample of people with Down syndrome, studied from infancy, has now been followed up at the age of 50 years. From the original sample of 54, there were 27 still in the study at the age of 50, all but four of the losses resulting from deaths. Methods: Intelligence and language skills were tested and daily living skills…

Background: Research into the neuropsychology of pediatric obsessive--compulsive disorder (OCD) reveals inconsistent results, limiting the ability to draw conclusions about possible neurocognitive deficits in youth with OCD. The aim of this study was to conduct a meta-analysis of the available literature. Methods: We identified 36 studies, of…

Background: Research on retelling ability and cognition is limited in children with cerebral palsy (CP) and speech impairment. Aims: To explore the impact of expressive and receptive language, narrative discourse dimensions (Narrative Assessment Profile measures), auditory and visual memory, theory of mind (ToM) and non-verbal cognition on the…

This study investigated the longitudinal relation between children's theory of mind and their metacognitive knowledge with a special focus on the impact of language on this relation. Measures of theory-of-mind understanding and metamemory knowledge were assessed in 133 3-year-old children at 4 measurement points separated by half-year intervals.…

This study considered how far nonverbal cognitive, language and reading abilities are affected by common genetic influences in a sample of 312 typically developing Chinese twin pairs aged from 3 to 11 years. Children were individually given tasks of Chinese word reading, receptive vocabulary, phonological memory, tone awareness, syllable and rhyme…

The Reynolds Intellectual Assessment Scales (RIAS) is a recently developed, individually administered psychometric instrument designed to measure general cognitive ability, as well as verbal (crystallized) intelligence, nonverbal (fluid) intelligence, and memory. Test reviewers have recommended the use of the RIAS despite the fact that, although…

Twenty primary abilities were measured using the Comprehensive Ability Battery. Factor analysis produced six oblique second-stratum factors. Four were identified as capacities in Cattell's triadic theory of ability structure. Correlations among factors yielded three oblique third-stratum factors. Implications for a hierarchical conceptualization…

Investigated a prior classification of Wechsler Memory Scale-Revised (WMS-R) subtests into Verbal and Visual categories. Findings from 45 college students found that memory test performance correlated significantly with performance on subtests of Form II of Luria-Nebraska Neuropsychological Battery that measures substrates of particular memory…

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…

The Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet: Fourth Edition (S-B:FE) were administered in counterbalanced order to a sample of 20 middle-class preschool children (11 males and 9 females) attending the Early Childhood Preschool Center located in a suburban area of a large midwestern city. Subjects' mean age was 4…
