Abstract
Six male albino rats were tested daily for 39 days on a five-choice multiple path elimination problem in which paths were differentially covered (by sandpaper, burlap, velure, etc.) and in which the order of elimination was not controlled in any way by the E. All Ss solved the problem, attaining the criterion much more rapidly than a parallel group had achieved such solution with uniformly surfaced wood paths. Variation in patterns of response on successive trials was characteristic of Ss while they maintained high accuracy. Strong preferences were displayed for selecting, on successive runs, paths that diverged maximally from each other.
