Hypothesis tests and summaries of the main effects (across dyads and triads) of Δ<i>roughness</i>, Δ<i>harmonicity</i>, and Δ<i>mean pitch</i>, in the five groups of participants.

‘Mean’, ‘Q5%’, and ‘Q95%’ are the mean and 90% equal-tailed credibility interval for the logit-scale effect of a standard deviation increase in roughness and harmonicity, and a one-semitone increase in mean pitch. ‘Evid.ratio’ is the odds the effect is in the direction specified by the hypothesis, while ‘Post.p’ is its associated posterior probability. ‘ROPE’ is the probability the effect is practically equivalent to zero [65], which we define as being in the interval [−0.036, 0.036].
