Abstract: The purpose of this research was to elucidate the nature and ontogeny of spatial information processing in hamsters. The study consisted of a series of spatial tasks administered to hamsters reared under different conditions. Experiment 1 demonstrated that hamsters reared on solid food, but not hamsters reared on a liquid diet, increased their exploratory behavior after a change in the spatial location of two odor cues when forced to adopt an allocentric frame of reference. Experiment 2 showed that 1iquid-reared hamsters could detect a change in the spatial location of odor cues if allowed to adopt an egocentric frame of reference. Experiment 3 showed that the liquid-reared hamsters could detect a change in the spatial location of two visual cues when forced to adopt an allocentric frame of reference. Experiment 4 compared a group of hamsters which experienced restricted exploratory experiences early in development with the 1iquid-reared and normally-reared animals tested in Experiment 1. A series of orthogonal comparisons indicated that the normally-reared group differed from both experimental groups. The restricted-rearing group and the 1iquid-rearing group did not differ and both failed to detect a change in the spatial location of odor cues from an allocentric frame of reference.
