Standard Practices for Interpretation of Psychophysiological Detection of Deception (Polygraph) Data
ABSTRACT
This practice establishes both the global and the numerical procedures for the systematic interpretation and analysis of psychophysiological detection of deception (PDD) data. Examiners shall use the method for which they have been formally trained, and these procedures shall be correctly matched to the PDD examination format.
SCOPE
1.1 These practices establish procedures for the systematic interpretation and analysis of Psychophysiological Detection of Deception (PDD) data.
1.2 Any test data analysis procedure used shall be correctly matched to the PDD examination format. Examiners shall use evaluation methods for which they have been formally trained.
1.2.1 Acceptable test data analysis procedures are those published in refereed or technical journals, and for which published replications of the procedures have confirmed their efficacy.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
