METHOD FOR DETECTING DECEPTION AND PREDICTING INTERVIEWER ACCURACY IN INVESTIGATIVE INTERVIEWING USING INTERVIEWER, INTERVIEWEE AND DYADIC PHYSIOLOGICAL AND BEHAVIORAL MEASUREMENTS

摘要

Existing approaches for deception detection are primarily based on polygraph systems that measure specific channels of physiology in highly structured interviews and that are interpreted by trained polygraph examiners. Existing approaches for predicting interviewer accuracy involve interviewers' own estimates of their performances which inevitably are biased. The methods and systems described herein provides objective, quantitative and automated metrics to detect deception and predict interviewer accuracy. Physiological information of the interviewer during the interview is recorded by at least a first sensor. The physiological information includes a time series of physiological data. An interview assessment is calculated by a computer. By processing the recorded physiological information, the interview assessment indicates at least one of whether a statement made by the interviewee is likely to be deceitful and whether the interviewer is likely to be accurate in estimating truthfulness of the interviewee. The interview assessment is output by the computer.

1. A method of detecting deception by an interviewee and predicting accuracy by an interviewer in an interview conducted by the interviewer, comprising:
recording, by at least a first sensor, physiological information of the interviewer during the interview, wherein the physiological information includes a time series of physiological data; calculating, by a computer, an interview assessment by processing the recorded physiological information, the interview assessment indicating at least one of whether a statement made by the interviewee is likely to be deceitful and whether the interviewer is likely to be accurate in estimating truthfulness of the interviewee; and outputting, by the computer, the interview assessment.
