The following data was collected for two groups of elderly males. The first group (n = 36) were identified as males with no evidence of senility. The second group (m = 12) were males identified with senility. The measurements taken were scores on subtests of the Weschler Adult Inteligence Scale:: 1. Information (I) 2. Similarities (S) 3. Arithmetic (A) 4.
