Sex differences in sensitivity to electric shock in rats and hamsters

Abstract

c and hamsters of both sexes using both the flinch-jump and spatial-preference techniques. In agreement with earlier work, female rats had lower thresholds in the flinch-jump test, but there was no sex difference when sensitivity was assessed by the spatial preference method. Hamsters displayed a different pattern of sex differences. Female hamsters had higher aversion thresholds in the spatial preference test, but there was no sex difference in the flinch-jump test. © 1977, The Psychonomic Society, Inc.. All rights reserved.
