Abstract
Scores obtained when the Wechsler Adult Intelligence Scale was administered by a trained examiner were compared with those obtained when the test was administered mechanically. Ss, 40 university students, were given half the items of the WAIS Verbal scale by an examiner and half by machine. Analysis of the scores obtained under these two modes of test presentation, using Lindquist's Type V “mixed” design, showed no significant differences in performance, except for the Information subtest. Scores on the Information subtest, when administered by the examiner, were significantly higher than when administered mechanically.
