title: Responsiveness patterns and handedness differences in bilateral electrodermal asymmetry.
abstract: 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.
