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 …
Abstract This study aimed to revise the Epreuve de Performance Cognitive (EPC), a nonverbal, sequential reasoning test, by incorporating a stopping requirement after five consecutive misses, and to evaluate the psychometric properties of the revised EPC. Data from 1,764 test takers were analyzed using various statistical methods. The revised EPC …
Abstract The purpose of this study was to analyze the item structure of the General Knowledge Subtest in the Jouve Cerebrals Crystallized Educational Scale (JCCES) using multidimensional scaling (MDS) analyses. The JCCES was developed as a more efficient assessment of cognitive abilities by implementing a stopping rule based on consecutive …
Abstract The TRI52 is a computerized nonverbal intelligence test composed of 52 figurative items designed to measure cognitive abilities without relying on acquired knowledge. This study aims to investigate the reliability, validity, and applicability of TRI52 in diverse populations. The TRI52 demonstrates high reliability, as indicated by a Cronbach’s Alpha …
Abstract The Cerebrals Cognitive Abilities Test (CCAT) is a psychometric test battery comprising three subtests: Verbal Analogies (VA), Mathematical Problems (MP), and General Knowledge (GK). The CCAT is designed to assess general crystallized intelligence and scholastic ability in adolescents and adults. This study aimed to investigate the reliability, criterion-related validity, …
