The stress we feel when discussing an uncomfortable topic is often reflected by the movements to form a protective barrier. In general, when people are not concerned about a topic their arms and legs are left uncrossed and they look relaxed. When stress rises they tend to close physically crossing their arms and legs to defend the stomach area. The abdominal region is vulnerable and we feel the need to protect it when threatened. Therefore when an applicant maintains an open body position when questioned about his biographical information, but closes physically when he is asked about his job history, it may possibly indicate a concealment of derogatory information.
Many people also avoid eye contact with their questioner when attempting deception.
As discussed earlier there may be numerous reasons why truthful people will avoid eye contact but deceivers are almost always reluctant to make eye contact because of the fear of detection. Two questions should be asked about eye contact. Second, can the applicant maintain eye contact at moments of stress. When applicants look away under these circumstances they may use created jobs as a cover. Created jobs might be picking lint, or scratching, any activity that must be supervised by the eyes.
