Hypothesis tests and summaries of the models’ principal effects across the five groups of participants (the hypotheses are detailed in the main text).

‘Est’, ‘Q5%’, and ‘Q95%’ show the mean and 90% equal-tailed credibility interval for the effect of Min to Maj compared to Maj to Min (H1) or a one-semitone increase in mean pitch (H2–H4). This effect is expressed on the logit (log-odds) scale. ‘Evid.ratio’ is the odds that the effect is in the direction specified by the hypothesis, and ‘Post.p’ is the associated posterior probability of the hypothesis (Evid.ratio = Post.p/(1 − Post.p)). We consider evidence ratios > 10 to be strong evidence; > 30 to be very strong. ‘ROPE’ shows the probability that the effect is small enough to be practically equivalent to zero [27], which we define as being in the interval [−0.18, 0.18].
