Table 3.

Mean, standard deviation, and statistical tests indicating depth sensitivity and preferences in all ROIs for Experiment 2. N = 16, except for FFA (N = 15). Bold text on the planned pairwise comparisons reflects the depth condition with significantly greater activation. “Pref” denotes preferred depth plane, “(F)” denotes front, “(B)” denotes back, and “Avg(B + F)” denotes the average of back and front. Since none of the pairwise comparisons reached significance in FFA, the preferred depth for the mixed comparison was determined by the greatest numeric activation. Since the scene regions generally demonstrated a bimodal depth preference, we compare the mixed depth activation to both back and front in PPA, OPA, and RSC.
