Electrodermal Response in the Squirrel Monkey

Abstract

An effort to find evidence of electrodermal response in the squirrel monkey ( Saimiri sciureus), as found in man, some infra-human genera of Simiae, and some lower mammals and amphibians, failed to locate an example. Given anatomical considerations, the availability of this response in Saimiri was suspected. In this study, using the skin conductance (constant voltage) method, monophasic electrodermal response as a result of novel or startle stimuli presentation was detected and a range of skin conductance level for test cases was determined.
