Abstract

Harmonic priming studies have reported facilitated processing for chords that are harmonically related to the prime context. Responses to the target (the last chord of an 8-chord sequence) were faster and more accurate when the target was strongly related, i.e., a tonic chord, to the preceding prime context than when it was less related, i.e., a subdominant chord. Results have been interpreted in terms of musical expectations and processing speed: the prime allows listeners to develop expectations for future events which lead to facilitated processing of the most strongly expected event. The present experiment investigated an alternative hypothesis suggesting that the harmonic structure of the prime context might create an ambiguity about "when" to respond that is stronger in contexts ending on less related targets than in contexts ending on strongly related targets. A change of musical timbre was used as surface marker indicating without ambiguity the temporal occurrence of the target. Participants made speeded intonation judgments of the target, i.e., judging whether targets are acoustically consonant or dissonant. The findings replicate the previously reported priming effect and rule out that processing differences are solely due to ambiguities about when in time the target will occur.
