"Do You Hear What I Hear?": Deception Detection by the Blind.
Sahlman, James M.; Koper, Randall J.
This study compared deception detection accuracy and confidence levels for 72 blind and 71 sighted participants with only audible cues available. Participants from a community blind center and a small western university judged stimulus tapes, which consisted of deceptive and truthful audio messages. Deceptive messages were induced by implicating students in a cheating incident. Subjects rated several audible cues, including speech errors, pauses, vocal segregates, response duration, vocal certainty, vocal tension, and vocal pleasantness. Subjects also judged the veracity of the messages and indicated the confidence in their judgments. Results indicated that blind participants tended to be more accurate at detecting deceptive communication than sighted participants, findings that suggest that sensory compensation may occur in blind individuals. No intergroup differences were found for ratings of audible cues; this finding did not support the speculation that finer distinctions in hearing ability for blind participants would produce ratings for deceptive statements that were higher than ratings of sighted participants. Additional analysis found that males were more accurate at detecting deception than females, results that contradict those of previous studies. (Contains approximately 60 references.) (JDD)
