Abstract

The aim of this study is to contribute to the understanding of psychological processes that underlie faking on personality questionnaires and to answer whether faking is more or less cognitively demanding than answering honestly. We compared the responses and eye-tracking data on a personality questionnaire (IPIP 20) and social desirability scales (E-SDR and M-SDR). The participants were students of the University of Zagreb. The first paper to use eye-tracking methodology in this field of study was written by Van Hooft and Born (2012). They found that faking is less cognitively demanding than answering honestly, as evidenced by fewer fixations in a fake good condition. In contrast to Van Hooft and Born, to induce a more realistic selection setting and more complex processes while faking, we used a more specific instruction. The participants completed a personality questionnaire and a social desirability scale under two conditions: first they were instructed to answer honestly and later they were told to present themselves as an ideal candidate for a nurse position or a managerial position. We found no differences in the number of fixations between the two conditions on the personality questionnaire. Meanwhile, on the E - SDR scale, the respondents had fewer fixations in the fake good condition. Based on these results, we cannot draw clear conclusions in regard to faking on personality questionnaires, however it seems that faking on SDR scales could be less cognitively demanding task than answering honestly.
