The authors have measured the correlation coefficient between W.B. and P.M. scores in 80 normal subjects, comparable for age and school. A mutual relationship between the two tests, connected by the hypothetical general intelligence factor "g", was really demonstrated. Correlation coefficient was positive and significative between W.B. total scores, excepted verbal scores, and P.M., the highest one between subtests 8, 9 and P.M. The intra-tests correlation between W.B. total scores and each subtest score was also evaluated: between sub-tests 8, 9 and W.B. total scores the highest one again.

Abstract
The authors have measured the correlation coefficient between W.B. and P.M. scores in 80 normal subjects, comparable for age and school. A mutual relationship between the two tests, connected by the hypothetical general intelligence factor "g", was really demonstrated. Correlation coefficient was positive and significative between W.B. total scores, excepted verbal scores, and P.M., the highest one between subtests 8, 9 and P.M. The intra-tests correlation between W.B. total scores and each subtest score was also evaluated: between sub-tests 8, 9 and W.B. total scores the highest one again. A new qualitative interpretation of mental deterioration in clinical neurology and psychiatry is suggested on the base of these results.
