隠匿情報検査で用いる呼吸測度解析のための解析区間スライド法の考案

 A time interval-sliding (TIS) method was developed for analysis of respiratory measures such as respiratory line length (RLL) and weighted average (WA) that are used in concealed information tests (CIT). The validity of this method was tested using simulations. The TIS method shifts the time interval such that its starting point for an analysis shifts to the bottom of the respiratory cycle. In study 1, it was demonstrated that negative influences on RLL and WA caused by a starting point of analysis could be solved using the TIS method. In study 2, the efficacy of the TIS method was tested using CIT simulations. The results of these two studies indicated that the TIS method improves discriminability of RLL and WA. It was also found that the discriminability of the RLL was improved to the same level as those of the WA, although the RLL values were lower than those of the WA prior to operating the TIS method. Therefore, it can be expected that the TIS method will be an effective technique for the analysis of respiratory measures of CIT.
