| Abstract |
| The purpose of present study was to examine brain functions associated with intention to conceal information. Kubo & Nittono(2009) and Verschuere et al.(2009) studied the intention to conceal information using P300 amplitude. On the basis of these two studies, present study attempted to identify brain area while participants were performing concealed information test. 19 healthy college students participated in fMRI-based concealed information test. Participants` name were used as concealed information. The test was performed in two conditions. In the intention condition, participants were instructed to try leaving their names undetected by suppressing their brain response to it. In the no intention condition, participants performed the test without intention to conceal. The fMRI results showed that the right anterior cingulated cortex (Rt. ACC), and left orbito-frontal cortex (Lt. OFC) activations were greater in the deceptive condition than the truth condition. These finding confirmed that ACC is area a deception-specific process as shown in the previous fMRI study. The OFC activation was also observed in the deceptive condition. The OFC is an area known as associated with emotional response such as anxiety, fear, and guilty. The anxiety induced while participants were intended to conceal information might be related to the OFC activation. |
