The aim of the present study was to examine the relationship between subjects' handedness and electrodermal asymmetry when subjects were divided according to their electrodermal Responsiveness Patterns, obtained during a stimulus-free period. Skin conductance was bilaterally recorded in a sample of 48 subjects (24 dextrals and 24 sinistrals) during the performance of two tasks (watching a film and listening to neutral tones). Subjects were divided into four groups of 12 subjects each (dextral right-hand responders, dextral left-hand responders, sinistral right-hand responders and sinistral left-hand responders). No differences were found between dextral and sinistral subjects. Orientation of electrodermal asymmetry in each Responsiveness Patterns remained constant throughout the two conditions: right-hand responders showed higher electrodermal activity on their right hand, while left-hand responders showed higher electrodermal activity on their left hand. In addition, left-hand responders showed a slower habituation rate on their left hand than on their right hand, whereas right-hand responders showed no significant differences between hands.
本研究的目的是，在根据无刺激期获得的皮肤电反应模式对受试者进行分组的情况下，检验受试者的利手与皮肤电不对称性之间的关系。在48名受试者（24名右利手者和24名左利手者）执行两项任务（观看电影和聆听中性音调）期间，双侧记录其皮肤电导率。受试者被分为四组，每组12名受试者（右利手右手反应者、右利手左手反应者、左利手右手反应者和左利手左手反应者）。右利手者和左利手者之间未发现差异。在两种情况下，每种反应模式下皮肤电不对称性的方向保持不变：右手反应者右手的皮肤电活动较高，而左手反应者左手的皮肤电活动较高。此外，左手反应者左手的习惯化率比右手慢，而右手反应者双手之间没有显著差异。
