Reactions of Ferret-Polecat Hybrids to Complexity and Change

Abstract

Ferret-polecat hybrids entered the more visually complex of 2 Y-maze arms more often during a 60-sec. period. In Exp. 2, when Ss were faced with a familiar complex arm and a less complex novel one, they chose the novel arm first but entered the complex arm more frequently during another 60-sec. period. They also entered an arm more quickly when run before feeding than when run afterwards. These findings resembled those reported for rats, thus extending the range of species known to be reactive to spatial changes in visual stimulation.
