Critical features underlying recognition of the default object views. A, Rat group average performance at discriminating the default object views was significantly lower in bubbles trials (light gray bar) than in regular trials (dark gray bar): p < 0.001 (one-tailed, paired t test). Both performances were significantly higher than chance: ****p < 0.0001 (one-tailed, unpaired t test). Error bars indicate SEM. B, For each rat, the saliency maps resulting from processing the bubbles trials collected for the default object views are shown as grayscale masks superimposed on the images of the objects. The brightness of each pixel indicates the likelihood, for an object view, to be correctly identified when that pixel was visible through the bubbles masks. Significantly salient and antisalient object regions (i.e., regions that were significantly positively or negatively correlated with correct identification of an object; p < 0.05; permutation test) are shown, respectively, in red and cyan.
