Polygraph examination: a psychophysiological test of deception or recognition sometimes referred to as lie-detection as a term of convenience. The polygraph examination is a standardized, evidence-based test of the margin of uncertainty or level of confidence surrounding a categorical conclusion of deception or the possession of knowledge or information regarding a test target issue. Test data are a combination of physiological proxies that have been shown to vary significantly with different types of test stimuli as a function of deception or truth-telling in response to the relevant investigation target stimuli as a function of deception or truth-telling in response to the relevant investigation target stimuli. The psychological basis of responses to polygraph stimuli is thought to involve attention, cognition, emotion, and behavioral conditions. The examination consists of an interview phase, to clarify the issue under investigation and related test stimuli, a data acquisition phase, during which physiological responses to test stimuli are permanently recorded, and an analysis phase during which differences in responses to different types of test stimuli are numerically quantified to calculate a statistical classifier for a categorical test result. The examiner may also provide the examinee an opportunity to explain any physiological responses and resolve any remaining inconsistencies.
Post Conviction Sex Offender Testing (PCSOT) Examiner: a polygraph examiner who conducts examinations of sex offenders as a condition of treatment, probation, parole or supervised release, and who has completed specialized training consistent with APA standards.
EyeDetect Lie Detection
5 Steps of an EyeDetect Test
1) The person being tested sits in front of an EyeDetect Station,
which is a computer equipped with a high-defnition,
infrared eye-tracking camera. The eye tracker is calibrated
to monitor involuntary eye behavior.
2) The person answers a series of true/false questions for 30
3) The question responses, along with pupil changes and
other eye behavior, are measured and stored on a secure,
4) At the conclusion of the test, the eye measurements and
test responses are uploaded to a secure cloud server where
it is analyzed by proprietary algorithms.
5) A detailed report is generated within 5 minutes, and a
Converus Credibility Index Score indicates whether the
person is credible or deceptive to the questions asked.
Although Polygraph Testing Is A Great Investigative Tool It Is Not A Substitute For A Thorough Investigation!
