“…However, it is a complicated process. For example, it is also known that lateral eye movements affect sound localization the same way (Suzuki 2008) and even neck proprioceptive signals influence sound perception. That eye movements affect sound localization may seem surprising, however it has the effect of re-centering the auditory stage to where the gaze is.…”

Some researchers have hypothesized the existence of a specialized brain unit for beat perception in music which is directly influenced by vestibular stimulation arising from motion. They also suggest that the unit is involved in the entrainment of movement to music. However, the data used to support this hypothesis may be explained by a simpler phenomenon: the audiogravic and audiogyral effect. This effect is not related to beat perception at all but deals with perceived sound changes under accelerations. If the perception of a sound changes as a consequence of acceleration of the vestibular system, and those accelerations are timed to coincide with particular beats in a stream of unaccented beats, then those beats will actually sound different. The detection of a given meter in that unaccented stream will therefore arise from this change in sound processing, with no need for a specialized brain mechanism for beat perception. There is no direct evidence supporting the existence of an innate brain unit.

“…Indeed, Lewald and Karnath (2001) summarize their findings in their abstract by stating "…that vestibular information is taken into account by the brain for accurate localization of stationary sound sources during natural head and body motion". Suzuki et al (2008) show that spatial perception of objects involves interaction between auditory, visual and vestibular systems, and that visual information dominates over auditory information. This finding is not surprising since the visual system can more accurately locate objects in space than can the auditory system.…”

“…Now to the interesting part of Riggle's paper. He discusses research by Graybiel (Clark & Graybiel, 1949; Graybiel & Niven, 1950), Lewald and Karnath (2001), and Suzuki (Suzuki et al, 2008) showing that in determining where sounds are coming from in space, the auditory system is influenced by vestibular input, just as the visual system is influenced by vestibular input when calculating where objects are located in space. Indeed, it is critical to use vestibular information for auditory space perception.…”

In a series of studies we have shown that movement (or vestibular stimulation) that is synchronized to every second or every third beat of a metrically ambiguous rhythm pattern biases people to perceive the meter as a march or as a waltz, respectively. Riggle (this volume) claims that we postulate an "innate", "specialized brain unit" for beat perception that is "directly" influenced by vestibular input. In fact, to the contrary, we argue that experience likely plays a large role in the development of rhythmic auditory-movement interactions, and that rhythmic processing in the brain is widely distributed and includes subcortical and cortical areas involved in sound processing and movement. Further, we argue that vestibular and auditory information are integrated at various subcortical and cortical levels along with input from other sensory modalities, and it is not clear which levels are most important for rhythm processing or, indeed, what a "direct" influence of vestibular input would mean. Finally, we argue that vestibular input to sound location mechanisms may be involved, but likely cannot explain the influence of vestibular input on the perception of auditory rhythm. This remains an empirical question for future research. KEYWORDS: rhythm, meter, vestibular, experience-dependent, multisensory, sound location IN his paper "A simpler explanation for vestibular influence on beat perception: No specialized unit needed", Riggle (this volume) misinterprets our papers (Phillips-Silver & Trainor, 2005, 2007Trainor et al., 2009) on movement-auditory interactions, and then presents evidence that he claims contradicts our findings. However, nothing in his paper actually argues against any of our findings. Because questions related to the mechanisms of auditory-vestibular interaction -and their phylogenetic and ontogenetic origins -are of fundamental importance in understanding both auditory perception and musical behaviour, in this reply we will engage in a constructive discussion of the critical question concerning whether auditory-vestibular interactions for rhythm are explained by auditory-vestibular interactions for locating sounds in space. But first it is necessary to set the record straight with respect to our experimental findings and our interpretation of the results.In the series of studies cited above, we have shown that when played a metrically ambiguous auditory rhythm (i.e., one with no physical accents), both adults and infants can be biased to perceive it as a march (with perceived accents every second beat) or as a waltz (with perceived accents every third beat) by engaging them in rhythmic movement synchronized to every second or every third beat of the ambiguous auditory rhythm, respectively. Furthermore, we have shown that stimulation of the vestibular nerve in such a way as to give rise to the sensation of head movement synchronized to every second or to every third beat of the metrically ambiguous rhythm (in the absence of actual movement) also biases metrical interpretation for a marc...
