Early research that relied on standardized assessments of intelligence reported negative effects of bilingualism for children, but a study by Peal and Lambert (1962) reported better performance by bilingual than monolingual children on verbal and nonverbal intelligence tests. This outcome led to the view that bilingualism was a positive…

Purpose: Pitch plays an important role in auditory perception of music and language. This study provides a systematic review with meta-analysis to investigate whether individuals with autism spectrum disorder (ASD) have enhanced pitch processing ability and to identify the potential factors associated with processing differences between ASD and…

The present study presents a meta-analysis of the relations between phonological processing abilities and different mathematics subskills. Using a random-effects model with 94 studies (135 unique samples, 826 effect sizes), the present meta-analysis revealed a significant general association between phonological processing and mathematics (average…

With the number of new and revised nonverbal and language-reduced tests of cognitive ability, selection and interpretation of appropriate measures can be complicated. Seven nonverbal or language-reduced tests with normative data collected within the last 15 years were evaluated. Besides evaluating technical adequacy, other variables affecting test…

This study determined the effect of matching children with specific language impairment (SLI) and their peers with typical development (TD) for nonverbal IQ on the IQ test scores of the resultant groups. Studies published between January 2000 and May 2012 reporting standard nonverbal IQ scores for SLI and age-matched TD controls were categorized…

Background: This systematic review aimed to identify the factors related to psychosocial outcomes for adults with high-functioning autism spectrum disorder (HFASD).

While the number of English Learners (ELs) continues to grow rapidly in the United States, corresponding proportions of ELs are not found in gifted and talented education programs across the nation. The underrepresentation of ELs in gifted programs is both a societal and a research problem. This report presents the results of a systematic review…

Assessment is a crucial component of gifted education. Not only does it facilitate the recognition of the potential and specific needs of gifted students, it also monitors the progress and growth of gifted students, and allows for the evaluation of gifted education programs.

A meta-analysis was undertaken to reexamine near- and far-transfer effects following working-memory training and to consider potential moderators more systematically. Forty-seven studies with 65 group comparisons were included in the meta-analysis. Results showed near-transfer effects to short-term and working-memory skills that were sustained at…

Through a review of the literature on mathematical learning disabilities (MLD) and low achievement in mathematics (LA) we have proposed a model classifying mathematical skills involved in learning mathematics into four domains (Core number, Memory, Reasoning, and Visual-spatial). In this paper we present a new experimental computer-based battery…

This paper discusses issues on cross-cultural gifted screening from a Philippine perspective. Research on gifted education in the Philippines, and Southeast Asia in general, is still nascent. The main focus of this review of literature is on equity of the gifted education screening process across wide socioeconomic, cultural, and linguistic…

Given the paucity of research describing the use of the TONI-3 with urban children with disabilities, a brief review of the literature was conducted. While little relevant research was identified, the use of the TONI-3 was supported in a number of diverse settings. This paper also describes a study designed to examine the validity of the Test of…
