M, Medium; O, odor.
aThe order of discriminations was the same for mice, but the relevant dimension, and thus the direction of the EDS (odor to medium or medium to odor) was counterbalanced within each experimental group. The number of trials required to reach criterion (eight correct consecutive trials) was independent of choice of relevant dimension.
