| Summary: | In this study, we conceptually replicated two experiments by Crespo-Bojorque and Toro (2016; Experiments 4a & 5a) in an attempt to corroborate their finding of improved performance in abstract pattern learning within sequences of conventionally consonant versus dissonant dyads. In addition, to determine whether the processing advantages for consonance that they reported were due to the ratio simplicity or the familiarity of the stimuli, we added a condition in which participants were either presented with unconventionally tuned small versus large integer-ratio dyads. Results failed to replicate Crespo-Bojorque and Toro’s (2016) original findings: Neither conventionally consonant nor unconventionally tuned small integer-ratio dyads conferred any advantage in pattern learning or generalization. However, in a post hoc analysis using a subsample of participants with no music training, there was evidence that initial pattern learning was more efficient when the patterns were embedded within familiar as opposed to unconventionally tuned dyads. This is consistent with Crespo-Bojorque and Toro’s (2016) proposition that interval familiarity may bolster abstract pattern detection. Discussion centers on the need for additional research on the impact of consonance on pattern learning, highlighting the importance of adjudicating between the effects of ratio simplicity and enculturation.
