Comparability of EDA effects obtained with constant-current skin resistance and constant-voltage skin conductance methods

Journal Article


Abstract


  • EDA was recorded from one group of subjects by using a standard constant-voltage method and from another group by using polarizable electrodes, a hypertonic electrolyte, and a constant-current method with ac coupled output. The robustness of stimulus-response relationships for EDA was examined by comparing the groups over (counterbalanced) blocks of 10 auditory and 10 visual stimuli of low intensity. Both raw and range-corrected EDA measures showed significant novelty and modality effects without group differences, and high between-group correlations over means (r ⩾.87). These results indicate that SRR measures from field-type studies may validly represent EDA expected from a more rigorous application of SCR techniques. Respiratory pause was also examined in both groups and found to reflect only novelty changes. This lack of covariation with EDA is contrary to unitary OR theory but compatible with recent proposals of prehminary processes in OR elicitation. © 1981, Psychonomic Society, Inc..
