  1. For each task, we test whether the proportion of participants choosing stimulus C (tasks p1–p4.2) or stimulus D (tasks g1and g2) over stimulus A differs from chance (H₀: p = 0.5; the two stimuli have either equal absolute values in experiments p1, p2, p3, g1, and g2 or equal relative values in experiments p4.1 and p4.2). For each task, we show p̂, the observed choice proportions and the 95% binomial confidence interval. A p value < 0.05 (italic) indicates a significant group-level bias in favor of one stimulus.
