The Rank Order Scoring System (ROSS) for analyzing physiological detection of deception polygraph charts proposed by Honts and Driscoll (in press) for single issue tests was expanded for use with multiple issue tests. This expanded version of the ROSS was evaluated in comparison with standard numerical scoring on a set of 25 confirmed field cases obtained from a Federal law enforcement agency.
Abstract
The ROSS and standard numerical scoring were of about the same validity when subjects either responded truthfully or deceptively to all of the relevant questions on their examinations. However, standard numerical scoring significantly outperformed the ROSS on a subset of cases where subjects responded truthfully to some relevant questions but deceptively to other relevant questions during the same examination. Strengths, weaknesses, and possible applications of the ROSS were discussed. (Author abstract)
