Voluntary Control of Electrodermal Activity in Relation to Imagery and Internal Perception Scores

feedback of spontaneous Electro dermal fluctuation in human subjects increased their in frequency of occurrence relative to a non-contingent feedback control group. The effect was facilitated for subject having high imagery und/or high internal perception as measured by the Suphian Scale of Imagery (SSI) and Sophian Scale of Internal Perception (SSP) respectively. These data suggest the existence of individual differences in self-control of autonomic responses.
