Mimicry Deception Theory Applied To Grooming Behaviors Of Child Sexual Abuse, Melissa De Roos De Roos

Open Access Theses & Dissertations

Mimicry Deception Theory (MDT) is a theoretical framework used to analyze deception in terms of long- vs. short-term strategies employed by the deceiver. Grooming behaviors used by sex offenders to access child victims and to prolong the abuse while minimizing detection are a specific form of deception. We conducted two studies, coding 121 and 164 court reports of sex abuse appeal cases with child victims. Grooming that was more complex in nature was associated with abuse that lasted longer and was more difficult to detect. Further, victim vulnerabilities contributed to a sense of confusion in the victim, and a decreased …

Strategic Approaches To Lying: Understanding Their Impact On Psychological Processes, Cues To Deception, And Perceptions Of Observers, Stephen Worth Michael

Open Access Theses & Dissertations

The current research examined the strategies implemented by liars, the relationships between these strategies and psychological processes related to deception, and the implications of these associations on perceptions of deceptive statements. In general, deception research has either ignored or superficially examined the types of strategies that individuals use to construct lies. However, these strategies may have significant impact on characteristics of the lie itself, and in turn, perceptions of the lie.

Study 1 explored the various strategies that liars use and the association of these strategies to psychological processes involved in lying. Results demonstrated that participants used a wide range …

Intelligent Tutoring For Interviewing To Detect Deception: Can Investigators Be Trained To Attain And Detect Accurate Cues To Deception?, Justin Albrechtsen

Open Access Theses & Dissertations

The present study examined whether investigators can be trained to elicit and detect cues to deception. The study included two training conditions and a control condition. Participants in the virtual Human Intelligent Tutoring System (vHITS) conditions completed a training program for deception detection and investigative interviewing. The primary components of this training were one-on-one interaction with a virtual human and tutoring tailored to specific participant responses. Participants in the Computer Based Training (CBT) conditions completed a comparable training program for deception detection and investigative interviewing. However, this program provided a more passive training environment with no interaction between student and …

Training To Detect Deception: The Role Of Intelligent Tutoring Systems And Impression-Based Cues, Stephen Worth Michael

Open Access Theses & Dissertations

Research attempting to train individuals to detect deception has demonstrated small, inconsistent effects. The methods with which previous studies have trained participants and the cues to deception used in these training programs may be partially responsible for these findings. The current study investigated the effectiveness of a novel, interactive training program for deception detection which used an interview setting with virtual humans and an intelligent tutoring system. This training program was compared to a non-interactive training program. Participants were trained on eight indirect, impression-based cues that have been empirically demonstrated to be diagnostic of deception. Results demonstrated that indirect, impression-based …
