Chew’s study investigates the link between information processing speed and intelligence by utilizing elementary cognitive tasks (ECTs) as a measurement tool. The findings reveal a consistent negative correlation between reaction times on ECTs and intelligence scores, particularly as task complexity increases. This article unpacks these findings and their implications for …
Abstract This study aimed to investigate the underlying dimensions of the Jouve Cerebrals Crystallized Educational Scale (JCCES) Mathematical Problems (MP) using Alternating Least Squares Scaling (ALSCAL). The dataset consisted of intercorrelations between 38 MP items, with 588 participants. Various dimensional solutions were assessed for the goodness of fit. A 4-dimensional …
Frey and Detterman (2004) conducted an influential study examining the relationship between the Scholastic Assessment Test (SAT) and general cognitive ability (g). Their research sought to determine the degree to which SAT scores reflect g and assess the test’s potential use as a premorbid measure of intelligence. The findings provided …
Examining Cognitive Dimensions Through the Jouve-Cerebrals Test of Induction (JCTI) and the SAT This study investigates the dimensions of general reasoning ability (gθ) by analyzing data from the Jouve-Cerebrals Test of Induction (JCTI) and the Scholastic Assessment Test-Recentered (SAT). Focusing on the Mathematical and Verbal subscales of the SAT, the …
Research comparing IQ scores from the Stanford-Binet and the Wechsler Adult Intelligence Scale (WAIS) reveals significant differences. These findings hold implications for assessing intellectual disabilities, diagnosing cognitive impairments, and understanding the practical outcomes of these assessments. This analysis reflects on the study conducted by Silverman et al. (2010), which reported …
This article examines the structure and cross-age consistency of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). The research evaluates how the test aligns with the Cattell-Horn-Carroll (CHC) theory of intelligence and whether it measures the same constructs across different age groups. The findings offer valuable insights into the application and …
Abstract This study aimed to examine the relationships between the Jouve Cerebrals Crystallized Educational Scale (JCCES) Crystallized Educational Index (CEI) and various measures of cognitive abilities and academic achievement. Pearson correlation analyses were used to test the research hypotheses. The results showed strong correlations between the JCCES CEI and measures …
Abstract This study examined the relationship between the Jouve Cerebrals Crystallized Educational Scale (JCCES) and the Reynolds Intellectual Assessment (RIAS) Verbal Scale using Principal Component Analysis (PCA). The PCA revealed a strong relationship between JCCES and the RIAS Verbal Scale, supporting the hypothesis that there is a common underlying construct …
This study examines how educational attainment and gender intersect to influence performance on the Jouve Cerebrals Test of Induction (JCTI). By analyzing a diverse group of 251 individuals, the research highlights how cognitive performance varies across different stages of education and between genders. Background The JCTI has been widely used …
Abstract This research focused on assessing the reliability of the Jouve Cerebrals Test of Induction (JCTI), a computerized 52-item test measuring nonverbal reasoning without time constraints. The reliability of the test was determined through Cronbach’s Alpha coefficients and standard errors of measurement (SEm), calculated across various age groups. A total …
