Intelligence scales are widely employed in the assessment of gifted students. The Anadolu-Sak Intelligence Scale [ASIS], an intelligence evaluation tool originating from Turkey, is extensively used for identifying gifted students. This study aimed to investigate the cognitive profiles of gifted children using the ASIS. Participants were selected…

The Flynn effect, which advocated that there was a rise in the global IQ score, was widely accepted by the relevant scientific community. However, there are recent research findings that this effect has been reversed. In this study, both Flynn and anti-Flynn effects were investigated. The purpose of this study is to analyze students' general,…

An examination of gender-related differential item functioning was conducted on the verbal subtests of the Anadolu-Sak Intelligence Scale. Analyses were conducted using the scale standardization data (N = 4641). A Mantel-Haenszel statistic was used to detect differential item functioning (DIF). A total of 58 verbal analogical reasoning items, 20…

This study examined the independent contribution of morphological awareness and orthographic awareness in reading comprehension, controlling for working memory and reading fluency in Arabic-speaking children. Participants (N = 244) from grades four and five, were classified into typical comprehenders (n = 207) and poor comprehenders (n = 37). All…

Purpose: Two types of orthographic knowledge were examined: i) knowledge of permissible letter combinations (general orthographic knowledge) and ii) knowledge of whole words (word-specific orthographic knowledge), to gain further insights into the relationship of general and word-specific orthographic knowledge with literacy skills. Method:…

The main objective of this study is to assess the Spanish literacy competence of students enrolled in bilingual and trilingual programs by analyzing the developmental process and evolutionary course of reading during the first cycle of Primary Education. This analysis aims to determine whether the reading skills in Spanish of students in…

In the current study, we investigated the role of vocabulary knowledge in the relation between working memory (WM) and reading comprehension, in a sample of 55 typically developing 8-year-old Italian children. The role of WM in comprehension is well-established, as both involve similar processes for successful task performance (i.e., active…

Background: Number line accuracy (NL accuracy) shows improvement over the course of a school education. However, there are practically no cross-country longitudinal studies of NL accuracy over the whole course of elementary school. Aims: This study investigated the developmental trajectories of NL accuracy and its types across the elementary…

This study investigates school-age children's arithmetic operations performance while solving larger-size problems which produces interferences in memory. Complex problems can trigger competing responses in working memory, which are irrelevant to a task goal and increase the likelihood of interference from previously learned problems (De Visscher…

The current study examined the effectiveness of a reading curriculum of explicit instruction on the letter-sound knowledge of a sample of elementary-aged students with Down syndrome. The procedures were adapted from prior research (King et al., 2020; Lemons et al., 2018; Lemons et al., 2015). Three participants between 9 and 11 years old…

While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high mathematics achievement also have excellent symbolic number processing abilities. We investigated this question in 64 children (aged 8 to 10), i.e., 32 children with persistent high…

The Aurora-a test battery was applied to 520 students who were between the ages of 9 and 12 attending public and private schools in Istanbul to create the Turkish version of the Aurora-a Intelligence Test Battery (Aurora-a_TR), which was developed for children aged 9-12 years based on the Triarchic Intelligence Theory. The three sub-test scores…

Little attention has been paid to the role that low levels of cognitive development (or IQ) play among both left-behind children (LBCs) and children living with parents (CLPs) in the context of poor educational attainment in rural China. In this paper, we examine how general cognitive abilities contribute to the academic achievement gains of both…

Background/Context: Previous research in educational assessment has consistently emphasized the importance of reliability as a cornerstone of test quality. Traditional measures of reliability, such as test-retest and split-half reliability, offer a broad view of how internally consistent a measure is but overlook the variability in this internal…

There is a paucity of research on the day-to-day experiences of raising gifted children from the perspective of parents. This qualitative study aimed to delve deeply into the phenomenon by interviewing parents of elementary-age gifted children. We conducted 12 interviews with parents whose children attended gifted schools. The interview…
