title = "Selective olfactory exposure alters social and plant odor preferences of immature hamsters",
abstract = "Hamsters 6-42 days old learn to prefer or tolerate certain odors to which they are exposed. The particular preferences affected change with age. During the first postnatal week, a 1-hr exposure to a plant odor transiently eliminates its aversiveness. In contrast, plant odor preferences of hamsters 11-42 days old are minimally affected by olfactory exposure. However, some combinations of plant and hamster odors are significantly more attractive when familiar than when unfamiliar to hamsters 11 days and older. The observed preference differences suggest that some botanical odors, when unfamiliar, prevent concurrent social odors from influencing behavior.",

note = "Funding Information: Early olfactory experience influences the odor preferences of rats (Marr and Lilliston, 1969; Leon, 1975), guinea pigs (Carter, 1972), mice (Mainardi, Marsan, and Pasquali, 1965; Porter and Etscorn, 1974), and hamsters (CornweU, 1975). In hamsters, continuous exposure to any one of several plant odors selectively diminishes the odor's aversiveness during the first week of life. However, during the second postnatal week, the effect of rearing environment on odor preferences appears to diminish. By Day 12, each of the plant odors is neutral to naive pups as well as to pups reared in the particular odor (Cornwell, 1975). As the behavioral influence of botanical odors seems to wane, the influence of social odors-that is, odors produced by hamsters-appears to strengthen. The odor of shavings taken from the nest area of their own home cage attracts hamsters during the second, but not the first week of 1This research was supported by NIH and Sloan Foundation predoctoral grants to the M.I.T.
