An investigation of dissimulation on the MMPI by means of the "lie detector."

"The MMPI was administered in group form to approximately 300 undergraduate students. From this group 13 were selected who showed evidence of dissimulation. Nine appeared to be "faking good" and four "faking bad." These 13 Ss were each carefully matched with control Ss who had similar raw-score MMPI profiles with no evidence of dissimulation. All Ss were again given the MMPI while being tested by a Keeler Polygraph. The findings tended to support the value of the validating scales, although many specific hypotheses were not verified in a statistically significant manner. Implications of these findings were discussed."
