| Outline of Final Research Achievements |
This study focused on availability of a pupillary measure in the Concealed Information Test (CIT) for information or memory detection. Participants performed a mock theft and then underwent the CIT in both knowledgeable and unknowledgeable conditions while recording their pupil diameter and traditional autonomic measures such as electrodermal activities and heart rates. In the CIT, the item which a participant theft in the preceding mock theft task served as the relevant item, and the other items were irrelevant items.
Pupil diameter was larger in response to the relevant item presentation than irrelevant item presentations. This differential pupil response seemed to sustain over 10 sec. after stimulus onset. Detection efficiency of pupil measure was comparable with those of traditional autonomic CIT measures. Moreover, results provided preliminary evidence suggesting incremental validity of the pupillary measure in the CIT.
