Abstract: Two experiments were carried out to investigate the roles of joint accent structure and familiarity in delayed recognition of relatively long tonal melodies. Melodic themes of target melodies were defined by correlating contour-related pitch accents with temporal accents (accent coupling) during an initial familiarization phase. Later, subjects gave recognition responses to key-transposed versions of the target melodies as well as to decoys with same and different contour accent patterns. In Experiment 1, all to-be-recognized melodies occurred both in an original rhythm, which preserved accent coupling, and in a new rhythm, which did not. Listeners were best at distinguishing targets from different decoys, especially in the original rhythm. In Experiment 2, the familiarity of target tunes and the rhythmic similarity in recognition were varied. Similar rhythms preserved accent coupling, whereas dissimilar rhythms did not. Listeners were most adept in distinguishing familiar targets from different decoys (Experiment 2A), particularly when they appeared in novel but similar rhythms. However, in similar rhythm conditions, listeners also frequently mistook same decoys for targets. With less familiar targets (Experiment 2B), these effects were attenuated, and performance showed general effects of pitch contour.
