ABSTRACT
Once the investigator has completed the analysis phase, identifying which of the individuals that he has been interviewing is being deceptive, as well as the specific areas in which the subject is being deceptive, he must now begin the interrogation process. In order to be successful in his attack, the interrogator needs to make an assessment regarding the particular primary dominant personality that he is interrogating. The assessment of the subject’s personality gives the interrogator the framework upon which to build his interrogatory argument. That argument is designed to break the subject’s particular efforts at denial and to disguise his actions that are unacceptable or criminal. Those efforts of denial and disguise occur because the subject is attempting to exercise a stress-protection system that Sigmund Freud identified as an ego-defense mechanism (Campbell, 1971).
