“…However, the participants in Grantham's study had experience in auditory motion experiments, whereas our participants were all novices-an important difference. Moreover, auditory motion thresholds appear to increase with adaptation (Grantham, 1992), which would explain why some of our participants were able to perform the training section, but failed to succeed in experimental blocks. In Experiment 2, we tried to reduce these potential problems.…”

Three experiments were conducted examining unimodal and crossmodal effects of attention to motion. Horizontally moving sounds and dot patterns were presented and participants' task was to discriminate their motion speed or whether they were presented with a brief gap. In Experiments 1 and 2, stimuli of one modality and of one direction were presented with a higher probability (p = .7) than other stimuli. Sounds and dot patterns moving in the expected direction were discriminated faster than stimuli moving in the unexpected direction. In Experiment 3, participants had to respond only to stimuli moving in one direction within the primary modality, but to all stimuli regardless of their direction within the rarer secondary modality. Stimuli of the secondary modality moving in the attended direction were discriminated faster than were oppositely moving stimuli. Results suggest that attending to the direction of motion affects perception within vision and audition, but also across modalities.

“…In addition to the latter two studies, Grantham (1998) used non-individualized VAS and collectively these data indicate that spectral match and spatial overlap between probes and adaptors produce a strong AMAE that is invariant with azimuth location (unlike the MAA). The duration of the adaptation period also appears to play a role in the magnitude of the AMAE (as it does in vision), with the early studies reporting weaker AMAE using no preadaptation ( Grantham & Wightman, 1979 ) or a relatively short period (30 seconds; Grantham, 1989 ; Grantham, 1992 , 1998 ). Studies employing longer periods of adaptation (2 minutes; Dong et al., 2000 , 3 minutes; Carlile et al., 1998 ; Kurilowich, 2008 ), with “top-up” exposure to the adaptor between probe stimuli, all showed much larger and more robust AMAE.…”

The growing availability of efficient and relatively inexpensive virtual auditory display technology has provided new research platforms to explore the perception of auditory motion. At the same time, deployment of these technologies in command and control as well as in entertainment roles is generating an increasing need to better understand the complex processes underlying auditory motion perception. This is a particularly challenging processing feat because it involves the rapid deconvolution of the relative change in the locations of sound sources produced by rotational and translations of the head in space (self-motion) to enable the perception of actual source motion. The fact that we perceive our auditory world to be stable despite almost continual movement of the head demonstrates the efficiency and effectiveness of this process. This review examines the acoustical basis of auditory motion perception and a wide range of psychophysical, electrophysiological, and cortical imaging studies that have probed the limits and possible mechanisms underlying this perception.

“…Adaptation is ubiquitous in the auditory system, and specifically in the sound localization pathway. In psychophysics adaptation manifests as a shift in perceived stimulus position (Wright, 1960; Grantham, 1992; Kashino and Nishida, 1998; Carlile et al, 2001; Getzmann, 2004; Phillips and Hall, 2005). In vivo recordings have shown adaptation as a decrease in firing rate over time in the 8 th nerve (Javel, 1996; Avissar et al, 2007), and in interaural time difference (ITD) sensitive neurons in the inferior colliculus (Ingham and McAlpine, 2004), and auditory cortex (Malone et al, 2002).…”

Adaptation is commonly defined as a decrease in response to a constant stimulus. In the auditory system such adaptation is seen at multiple levels. However, the first-order central neurons of the interaural time difference detection circuit encode information in the timing of spikes rather than the overall firing rate. We investigated adaptation during in vitro whole-cell recordings from chick nucleus magnocellularis neurons. Injection of noisy, depolarizing current caused an increase in firing rate and a decrease in spike time precision that developed over ϳ20 s. This adaptation depends on sustained depolarization, is independent of firing, and is eliminated by ␣-dendrotoxin (0.1 M), implicating slow inactivation of low-threshold voltage-activated K ϩ channels as its mechanism. This process may alter both firing rate and spike-timing precision of phase-locked inputs to coincidence detector neurons in nucleus laminaris and thereby adjust the precision of sound localization.
