To evaluate the reliability of electrodermal lateralization, skin conductance response (SCR) and skin potential response (SPR) amplitudes were recorded bilaterally in 11 right-handed male students during 4 identical experimental sessions each a week apart. After a rest period of 5 min, a set of auditory stimuli (1000 Hz, 100 dB, 1 s) was delivered. Results of both recordings showed a significant lateralization for all sets of response in the majority of subjects, but the reliability of the right-left (R-L) differences was low from one session to another. However, results suggest the existence of different degrees in stability according to subjects. Otherwise, the R-L differences appear to be recording technique dependent. These results have implications for the influence of central and peripheral factors on electrodermal activity laterality.
为评估皮肤电侧化的可靠性，在11名右利手男性学生中，每周进行一次，共4次相同的实验，每次实验期间，双侧记录皮肤电导反应（SCR）和皮肤电位反应（SPR）的幅度。经过5分钟的休息期后，给予一组听觉刺激（1000赫兹，100分贝，1秒）。两次记录的结果显示，大多数受试者的所有反应组都有显著的侧化现象，但从一个实验到另一个实验，左右（R-L）差异的可靠性较低。然而，结果表明根据受试者存在不同程度的稳定性。此外，R-L差异似乎取决于记录技术。这些结果对中枢和外周因素对皮肤电活动侧化的影响具有启示意义。
