Efficiency of GSR detection of information with repeated presentation of series of stimuli in two motivational states

Investigated the possibility of reducing errors in the detection of information using the GSR by employing a longer interrogation with repetitions of the same critical item. 2 groups of 58 undergraduates were tested: the 1st was tested under instructions intended to arouse high motivation to beat the machine; the other was tested under low motivation to beat the machine. It was possible to reduce errors in information detection through a simple combination of GSRs obtained from 10 repetitions of the same interrogation sequence. Motivation did not produce any noticeable effect on the efficiency of detection of information.
