This study was conducted to examine the relationships between general intelligence test scores and race, ethnicity, gender, and parental education using the Naglieri General Ability Tests: Verbal, Nonverbal and Quantitative (Naglieri & Brulles, & Lansdowne, 2021) for three samples that closely match the U.S. population. Few differences…

Single-case design (SCD) is a quantitative experimental technique in which participants serve as their own control. The use of an effect size in SCD allows evaluation of outcomes as well as comparison of outcomes via meta-analyses. Characteristics of SCD research make the selection of an appropriate effect size complicated. Additionally, there are…

Mathematical performance plays a vital role in students' academic development. Studies have shown that some basic cognitive processes, including inductive reasoning, are critical for the development of mathematical performance. However, little empirical evidence has been accumulated regarding the association between inductive reasoning and…

Researchers have found that violent online game addiction has become a serious global problem that negatively affects younger people. This study used a cross-sectional research design to examine the effects of violent online game contact on individuals' academic procrastination. We further explored the mediating role of emotional self-regulation…

The study examined the cognitive processes involved in written sentence construction in children affected by prenatal alcohol exposure (PAE) when compared a control group of nonexposed typically developing children, and a contrast group of nonexposed children with various clinical diagnoses. Results indicated that children with PAE and those in…

This study examined the factor structure of the Detroit Tests of Learning Abilities, Fifth Edition (DTLA-5) using principal axis factoring, multiple factor extraction criteria, and the Schmid-Leiman orthogonalization procedures not utilized by test publishers. Results suggest that the publisher's six-factor structure model was over factored.…

The current study investigated whether a brief refutation text intervention could change college students' misconceptions about the malleability of their intelligence and abilities. Students from a 2-year college and a 4-year university in a large urban city in the Northeastern United States participated in experimental and control conditions. A…

Research has indicated that school aged (6-16 years) versions of cognitive assessment instruments have varying levels of linguistic demand, which could impact assessment results for placement purposes. However, a significant limitation to this research is the fact that it has not been replicated with cognitive assessment instruments used in…

Autism spectrum disorder (ASD) is a neurodevelopmental disability that can cause significant social, communication, and behavioral challenges yet it is defined and diagnosed by the absence or presence of behaviors described in, for example, the Diagnostic and Statistical Manual 5. Descriptions of the disorder include symptoms such as intellectual…

Ancillary index scales provide assessment professionals the opportunity to conduct a more comprehensive interpretation of a student's performance on the Wechsler Intelligence Scales for Children, Fifth Edition (WISC-V); however, little is known about the performance of children with autism spectrum disorder (ASD) on these scales. The ASD special…

Grade retention is one of the most discussed and controversial educational measures, and yet, it is still widely applied in many countries. Research investigating the effects of grade retention on students' psychosocial variables presents mixed findings, partly due to the variables assessed, methodological issues, and the length of the studies.…

The Nonverbal Literacy Assessment (NVLA) is a literacy assessment designed for students with significant intellectual disabilities. The 218-item test was initially examined using confirmatory factor analysis. This method showed that the test worked as expected, but the items loaded onto a single factor. This article uses item response theory to…

Reading fluency (RF) involves the automaticity of many distinct reading skills (e.g., pacing, word recognition, phonological awareness) and allows cognitive resources to be allocated to higher-order reading skills (e.g., comprehension, synthesis). Early identification of students at-risk for RF deficits is critical, but many screeners require a…

This study aimed to examine the influence of teacher support on student engagement in mathematics. A cross-sectional survey was employed to recruit 632 students from grades 7 to 9 in junior middle schools across China. Participants completed various scales, including a teacher support scale, an academic self-efficacy scale, and a student…

Early childhood teachers are critical in promoting young children's STEM learning. However, research indicates that early childhood teachers are unfamiliar with STEM and do not have confidence in their abilities and skills to implement STEM education. Despite this issue, previous research has focused less on early childhood teachers' STEM…
