Substantial research supports the salience of relatively longer interonset intervals (IOIs) in determining rhythmic group structure,1–4 yet little is understood about the neural underpinnings of the perceptual grouping process. Gestalt-based interpretations of perceptual processes underlying rhythmic groupings have been proposed and converge with orienting response theory, which proposes enhanced neural sensitivity following a change in IOI.6 In support of this, enhancement of the N1-P2 component of event-related potential (ERP) responses to the first sound in short rhythmic groups has been demonstrated.7 The current study investigated cortical responses to perception of rhythmic group structure by examining changes in EEG responses associated with participants’ active and passive perception of pitch/rhythm patterns. The study used the steady state visually evoked potential (SSVEP) to examine ongoing changes in 13-Hz EEG responses while participants listened to pitch/rhythm patterns
