Abstract

One hundred and forty community volunteers were prescreened for upper and lower quartile scores using the Balanced Inventory of Desirable Responding [BIDR; Paulhus, D.L. (1988). Assessing self-deception and impression management in self-reports: The Balanced Inventory of Desirable Responding. Unpublished manual. Vancouver, British Columbia; University of British Columbia, Measurement and control of response bias. In J. P. Robinson, P. R. Shaver, & L. Wrightsman (Eds.), Measures of personality and social-psychological attitudes (pp. 17-59). San Diego, CA: Academic Press, 1991], and classified into stable High (n = 14) and Low (n = 15) self-deception groups using the Self-Deceptive Enhancement subscale of the BIDR. Participants identified normal and anomalous computer-displayed playing cards [following Bruner, J. & Postman, L. (1949). Journal of Personality, 18, 206-223], presented for short (∼ 16 ms), then increasingly longer durations. High and low self-deceivers identified the normal cards equally rapidly. Highs, however, took twice as many trials as lows (M = 11.21, S.D. = 9.65, vs. M = 5.00, S.D. = 3.87) to identify the anomalous card correctly twice (t [16.85] corrected for unequal variances = -2.25, P = 0.019, one-tailed). Self-deception thus appears associated with impaired categorization of anomaly.
