Summary. An analysis of performance on the Jouve–Cerebrals Test of Induction (JCTI) and four GAMA subtests (Matching, Analogies, Sequences, Construction) points to a single dominant source of individual differences rather than two separate abilities. With N = 118, factor-analytic evidence favors a general reasoning factor that subsumes both spatial–temporal and …
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 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 …
