Time course of melody recognition: a gating paradigm study

Recognizing a well-known melody (e.g., one's national anthem) is not an all-or-none process. Instead, recognition develops progressively while the melody unfolds over time. To examine which factors govern the time course of this recognition process, the gating paradigm, initially designed to study auditory word recognition, was adapted to music. Musicians and nonmusicians were presented with segments of increasing duration of familiar and unfamiliar melodies (i.e., the first note, then the first two notes, then the first three notes, and so forth). Recognition was assessed after each segment either by requiring participants to provide a familiarity judgment (Experiment 1) or by asking them to sing the melody that they thought had been presented (Experiment 2). In general, the more familiar the melody, the fewer the notes required for recognition. Musicians judged music's familiarity within fewer notes than did nonmusicians, whereas the reverse situation (i.e., musicians were slower than nonmusicians) occurred when a sung response was requested. However, both musicians and nonmusicians appeared to segment melodies into the same perceptual units (i.e., motives) in order to access the correct representation in memory. These results are interpreted in light of the cohort model (Marslen-Wilson, 1987), as applied to the music domain.
