Since 1986, unparalleled advances have occurred in the psychophysiological detection of deception (PDD) processes and procedures, and this paper traces the emergence of a new emphasis in PDD research, the development of forensic psychophysiology as an academic discipline.
Abstract
The emergence of forensic psychophysiology as an academic discipline and the application of computer technology to PDD testing procedures has essentially ushered in an era that began with Lombroso in the late 1800's and has stimulated an avalanche of change for current and future research. The current thrust of research is directed toward evaluating new sensors and transducers, new means of digitizing physiological data, ways of analyzing data online, new diagnostic approaches with specifically designed algorithms for various test formats, and algorithms to identify the presence of countermeasure tactics during PDD tests. This research will enhance the scientific evaluation of existing PDD tests and will facilitate the introduction of totally new PDD test types and formats. The increase in PDD research will not only provide new and better PDD tests and diagnostic procedures but will also provide new knowledge to enhance the evolution of forensic psychophysiology as an academic discipline. 48 references
