Phasic electrodermal conductance responses were bilaterally recorded from 30 subjects (15 males and 15 females). After a 5-min adaptation period subjects were presented with two series of ten 80-dB tones each, with a 4-min rest period between the two series. Data from sinistrals, ambidextrous, and from subjects with familial sinistrality were excluded from statistical analysis. Males displayed more asymmetry between hands both in their non-specific and specific responses, with larger skin conductance responses on the left hand. Females showed a less marked asymmetry, with larger skin conductance responses on the right hand. Similar results were found in skin conductance levels. It was concluded that sex differences are an important variable in the study of electrodermal asymmetry.
对30名受试者（15名男性和15名女性）双侧记录了阶段性皮肤电传导反应。在5分钟的适应期后，向受试者呈现了两个系列，每个系列有十个80分贝的音调，两个系列之间有4分钟的休息时间。左利手、双手灵巧以及有家族性左利手的受试者的数据被排除在统计分析之外。男性在非特异性和特异性反应中双手之间的不对称性更大，左手的皮肤电传导反应更大。女性的不对称性不太明显，右手的皮肤电传导反应更大。在皮肤电传导水平上也发现了类似的结果。得出的结论是，性别差异是皮肤电不对称性研究中的一个重要变量。
