Abstract : The Guilty Knowledge polygraph test (GKT) and a variation of the test, the Guilty Actions Test (GAT), were compared in a laboratory setting. 84 men who committed or witnessed a mock crime answered "No", repeated items, or remained silent in response to items on the GKT or GAT. A monetary reward was promised for appearing innocent on the test. An interaction with scores based on skin resistance showed that innocent witnesses tested on the GKT scored more in the guilt direction than subjects in any other groups. Subjects required to say "no" were more reactive to key items than subjects in the item repetition or silence groups. Thoracic respiration scores showed a difference between guilty and innocent subjects.
