Statistical analysis used a paired, two-tailed, non-parametric Wilcoxon signed-rank test. The responses averaged across all 5 presence questions were larger (Z = 3.1, p = .002) for foreground occlusion (M = 4.2, SD = 1.1) than for non-foreground occlusion (M = 3.3, SD = 1.0). When the responses to each question were analyzed separately, significant differences between viewing conditions were found for all 5 questions (Z = 2.69, p = .007; Z = 3.26, p = .001; Z = 2.49, p = .01; Z = 2.79, p = .005; and Z = 2.36, p = .02, respectively).
