Figure 3. Preference decisions are less variable in a multisensory context and independent of experience.

Bars represent within-condition variance, averaged (±SEM) across conditions and animals (n=132, 132, 48 and 48, respectively). Two-way ANOVA on variance with factors Condition (unisensory, multisensory) and Experience (experience, no experience) yielded a significant effect of Condition (F1,321=4.30, p<0.05), but no effect of experience (F1,321=2.82, p=0.09).
