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, …
