The authors made the interesting discovery that normals tested with a word association test and then retested a week later tended to correct any deviant responses, even though they had no way of knowing what responses tended toward the pathological. An attempt was made to explain this finding in the light of current ego psychology—that the response was indicative of an adaptive, unconscious ego defense functioning. As further evidence of this, the authors cite their previous work with word association tests following the administration of LSD.
