| Abstract: | In a detection of deception experiment comparisons were made of the effects of 2 methods of stimulus presentation and 2 different subject tasks. The relevant-irrelevant method of stimulus presentation proved equally effective for both tasks, but the peak-of-tension method was significantly less effective where the S's task was to deceive as to the nature of guilty information possessed (guilty information paradigm) than it was where the task was to deceive as to the possession of any information (guilty person paradigm). In general, Ss found it easier to deceive in the guilty information paradigm, where they could attempt to "appear guilty" on a noncritical item and especially when they could anticipate the order of presentation of items (peak-of-tension method).
