This experiment examined the effects of unilateral stimulation on the relative magnitude and latency of skin conductance responses recorded bilaterally from the palms. The unilaterally applied stimuli were shocks to either the left or right forefinger and voluntary flexion of either the left or right foot. Additional stimuli consisted of binaurally presented tones and deep breaths. In a within‐Ss design, the 22 Ss were submitted to 18 repetitions of each stimulus. The unilateral shocks as well as the foot movements had the effect of augmenting the relative magnitude of skin conductance responses from the palm ipsilateral to the site of stimulation. The shocks were found to be somewhat more effective than foot flexion in producing this effect. The relative latencies of responses were also influenced by the shocks, with shorter latency responses occurring from the palm ipsilateral to the stimulus site. Consideration is given to the role of both suprasegmental and spinal‐cord mechanisms in mediating these effects of unilateral stimuli.
