Dissertation/Thesis Abstract

The effects of memory retrieval conflict on the construction of a deception
by Meek, Scott W., Ph.D., University of South Carolina, 2012, 105; 3507867
Abstract (Summary)

The purpose of this investigation was to examine the impact that long-term memory representations have on the ability to construct a deception. Twenty-five adults (18–40) were given a misinformation task originally used by Okado and Stark (2005), and then asked to alternate between responding deceptively and truthfully to test items shown during a fMRI scan. The results indicate that responses to misinformation items (regardless of lie or truth) showed stronger activation in the dorsal prefrontal cortex, while deceptive responses to consistent items showed stronger activation in the ventral prefrontal cortex. These results indicate that cortical activation patterns were stronger for source identification and working memory than they were for the act of deception.
