Statistical analysis using the multilevel linear mixed model and the repeated measures Bayesian ANOVA analyses.

A) Effect of the number of masks and of the targets’ alignment on the disappearance time when at least one target invisible. The random factor was participants’ identity. B) Effect of the number of masks, of the alignment, and of the event type (disappearance or reappearance) on the simultaneity of disappearance and reappearance events. The random factor was participants’ identity. A,B) df: degrees of freedom. AIC: Akaike’s Information Criterion. The Bayes factor was computed relative to the model with random effects only. χ2 was computed relative to the preceding simpler model.
