刺激强度与个体差异对心理生理测谎的影响

探讨不同说谎经验的被试在完成不同刺激强度的任务时，其生理反应和说谎分数的变化。结果表明，在测谎过程中，任务刺激强度不仅影响测试结果的有效性，而且与被试的生理反应和说谎分数成正相关；不同类型被试的说谎分数没有显著差异，测谎应对任何人群都普遍有效。

Factors Influencing Psychophysical Polygraph: Intensity of Stimuli and Individual Differences

The present study investigated the changes of physical responses and lie scores of the participants who had different mental endurance as they were completing the task with different intensity of the stimulus. The results showed that the intensity of the stimulus not only influenced the effectiveness of the measurement, but also correlated positively with the physiological responses and the lie scores of the participants. The results also suggested that the scores of the participants with different mental endurance were similar, and polygraph was generally effective to any public population.
