| Summary: | 碩士 === 中央警察大學 === 刑事警察研究所 === 90 === The purpose of this study is to investigate if the accuracy of Modified Peak of Tension Test（MPOT）is higher than Peak of Tension Test（POT）on “innocent- informed subjects”.
This study is a 2（guilty group v.s. innocent group）×2（POT v.s. MPOT）factorial mixed design. First, the subjects are assigned to two groups randomly, one is guilty, and the other is innocent. All the subjects know about “guilty knowledge”, and the difference between these two groups is only guilty subjects mock crime, but innocent subjects don’t. Second, according to Bradley, & Warfield（1984）, this study modifies POT, and all the subjects test with both POT and MPOT. The result shows that the accuracy of “MPOT-innocent group”（62.5%）is higher than “POT-innocent group”（25.0%）.
The literature has been reviewed clearly in the study, and some suggestion about future research and application has been given in the end.
