The correlations are significantly positive for the whole population (r = 0.63), for ten out of twelve half-year stages (5½, 6…11 years) and for bright (rho = 0.76, N = 36) and dull children (rho = 0.89, N = 53).The Progressive Matrices problems are correctly graded, but the frequencies of right answers do not decrease continuously and there are too many easy items. A revision of these factors and of the position of alternatives would improve the test.Certain types of wrong answers (choice of complete figure, perseveration, rotation, missing easy items) have been analyzed to examine their relation to intelligence, neurosis and brain-lesion (N = 78).On the whole there is a good correla...
