Abstract This study aimed to investigate the relationships between tasks of the Jouve Cerebrals Crystallized Educational Scale (JCCES) and General Ability Measure for Adults (GAMA) using multidimensional scaling (MDS) analysis. The JCCES measures Verbal Analogies, Mathematical Problems, and General Knowledge, while the GAMA assesses nonverbal cognitive abilities through Matching, Analogies, …
Abstract This study aimed to investigate the differentiation between cognitive abilities assessed by the Jouve Cerebrals Crystallized Educational Scale (JCCES) and General Ability Measure for Adults (GAMA). A sample of 63 participants completed both JCCES and GAMA subtests. Pearson correlation and factor analysis were used to analyze the data. The …
Abstract This study aimed to examine the relationship between the Jouve Cerebrals Crystallized Educational Scale (JCCES) and the American College Test (ACT) by conducting a factor analysis. The dataset consisted of 60 observations, with Pearson’s correlation revealing significant associations between all variables. The factor analysis identified three factors, with the …
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 …
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 …
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 …
