Acoustic Correlates of Lies.
Motley, Michael T.
The author reports the results of a study based on an assumption that there might be an association of certain acoustic variables with the telling of lies. Twenty subjects were asked to perform two tasks, each involving four short oral responses, one of which was a lie. The responses were subjected to spectrographic analysis, and the task of the experimenter was to predict which of the four responses in each set was the lie. When minimum duration of response was used as the criterion, the lie responses were accurately identified with a high degree of reliability. The second part of the study involved twenty additional subjects, who were asked to replicate the lie identifications on the same responses simply on the basis of what they heard on a tape. They were unable to make accurate identifications of lie responses, regardless of whether or not they were informed of the duration cue. The author views this study as an initial attempt to reveal certain interrelationships between components of the encoding process. (RN)
