2、e year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice establishes procedures for the systematicinterpretation and analysis of Psychophysiological D
3、etection ofDeception (PDD) data.1.2 Any test data analysis procedure used shall be correctlymatched to the PDD examination format. Examiners shall useevaluation methods for which they have been formally trained.1.2.1 Acceptable test data analysis procedures are thosepublished in refereed or technica

If they are not suit

Nothing shall preclude an evaluator from reportingevidence of countermeasures when this evidence exists.4.1.1.3 Use analysis methods generally recognized to beaccurate.4.1.2 When possible, numerical evalua

The

17、dividual cases, there arefive empirically established diagnostic features in the respira-tion channel. They are:4.2.3.1 Suppression of respiration amplitude.4.2.3.2 Slowing of breathing rate (increase in cycle time, orbradypnea).4.2.3.3 Change in the inhalation/exhalation time ratio.4.2.3.4 Apnea.4.
18、2.3.5 Rise in the baseline of the respiration cycles. All ofthe diagnostic features in respiration, except the rise in base-line, are captured by a common metric, respiration line length.4.2.4 There is one primary diagnostic feature in the electro-dermal channel that has been empirically confirmed.
