Proceedings of 9th Annual London Business Research Conference 4 - 5 August 2014, Imperial College, London, UK, ISBN: 978-1-922069-56-6 The Faking Mechanism of Candidates in Situational Judgment Test in Personnel Selection: The Interactive Relationship of Warning and the Ability to Identify Criteria Zhang Mengqi* and Bian Ran and Che Hongsheng In order to reveal the mechanism of faking in the area of personnel selection, experimental situational approach is taken in this study. Participants in this experiment consisted of 140 undergraduate volunteers, The Situational Judgment Test for Volunteers of the 2008 Beijing Olympic Games was used as the experimental material. Through variation in two aspects of the experiment, situation (selection situation/honest situation) ×warning on faking (yes/no) , This research studies the effects of Warning and Ability to Identify Criteria (ATIC) on faking. Based on the results, this study concludes: ○1 The Situational Judgment Test can be faked. ○2 ATIC affects faking and can positively predicts faking. ○3 The interaction between ATIC and warning can predict faking. More specifically, for candidates with a lower level of ATIC, providing a warning can decrease faking. Conversely, for candidates with a higher level of ATIC, a warning can increase faking. *Zhang Mengqi, Department of Psychology, Beijing Normal University, Email: zmq0930@gmail.com
