Systematic evaluation of polygraph tracings, variously called chart interpretation or test data analysis, is the final phase of the polygraph examination process.
In modern polygraph instruments, sphygmomanometer readings are The examiner notes on the chart when the exam begins, when questions are asked, and ( 6) interpreting the charts. Even though the examiner is the linchpin of the procedure, proponents acknowledge that there are serious problems on iliis Systematic evaluation of polygraph tracings, variously called chart interpretation or test data analysis, is the final phase of the polygraph examination process. Most psychologists agree that there is little evidence that polygraph tests can of a polygraph pen wildly gyrating on a moving chart is readily recognized symbol. The interpretation of "no deception" is also a potential limitation, since it may The polygraph chart presented above is a screenshot of an actual polygraph test. It is a typical chart produced by a state-of-the-art computer polygraph recording procedure and the polygraph examiner. Such a mental attitude may cause the person's reaction to be so erratic that no conclusive chart interpretation can be errors in chart scoring and interpretation. The critical question is not whether two polygraph examiners score polygraph charts consistently, but whether the
A polygraph instrument records and fllters the original analog signal. The output is a digital signal, a discretized time series with possibly varying sampling rates across instruments and channels. The polygraph typically records thoracic and abdominal respirations, electrodermal and cardiovascular signals (Figure 1).
The polygraph chart presented above is a screenshot of an actual polygraph test. It is a typical chart produced by a state-of-the-art computer polygraph recording on 5 channels. 2 channels record the subject's respiration, 1 channel records the Galvanic Skin Resistance, 1 channel records cardiovascular activity and the remaining channel records certain physical activity. A polygraph instrument records and fllters the original analog signal. The output is a digital signal, a discretized time series with possibly varying sampling rates across instruments and channels. The polygraph typically records thoracic and abdominal respirations, electrodermal and cardiovascular signals (Figure 1). Among first scoring systems for the polygraph, Backster’s 7-position scoring system (Backster, 1963) was to garner widespread acceptance and became the dominant approach to chart interpretation for the polygraph profession. It is the system from which virtually all other manual scoring systems are derived. One is the interpretation of the polygraph chart. Interpretation normally involves comparison of physiological responses to “relevant” questions (i.e., questions about the issue that is the focus of the examination) and responses to other questions that are asked for purposes of comparison. 3 Interpretation is often done by the examiner, who reviews the chart and may code it according to a standard protocol.
