“…The current hypothesis is that AR is caused by binding of the gap-delimiting edges of the long sound to the short sound. Without these sounds edges, the long sound is subject to AR (Nakajima et al, 2000;Remijn and Nakajima, 2005;Remijn et al, 2007;Kanafuka et al, 2007;Pérez et al, in preparation). Since AR in the shared-gap and pseudo-continuous stimuli occurs without sensory stimulation during the gap, we have called it modal auditory restoration (MAR).…”

“…In a variation of the gap-transfer illusion (Nakajima et al, 2000(Nakajima et al, , 2004Kanafuka et al, 2007), Remijn et al (2007) presented simultaneously a 2-s ascending-frequency tone glide (750-3000 Hz), and a shorter, 500-ms descending-frequency tone glide (1783( -1261. The onset of the shorter descending glide was delayed so that both glides crossed at their temporal mid-point (crossing point).…”

Three experiments measured the perceived continuity of two pure tones "flankers" through a masker containing a silence. Experiment 1 used a 2I-2AFC procedure; one interval contained two noise bursts separated by a silent gap, and the other contained two noise bursts separated by a tone of the same duration as the silence. Discrimination between masker conditions was very accurate when the flankers were absent but was impaired substantially when the flankers were present. This was taken as evidence that illusory flanker continuity during the silent gap was heard as similar to the physical presence of a tone in the gap. In experiment 2, performance remained poor when the flankers were frequency glides aligned along a common trajectory. Performance improved significantly when the flankers were misaligned in trajectory. In experiment 3, listeners rated directly perceived flanker continuity. Strong continuity was reported in the silent gap conditions for which poor performance had been observed in experiments 1 and 2. These findings show that continuity may be heard through a masker that cannot mask a physically continuous tone but can mask the flankers' offset and onset. The results are explained in terms of the perceptual grouping of onsets and offsets of the flankers.

“…For the auditory stimuli, the gap transfer illusion refers to the auditory stimulus pattern that embodies a short descending (or rising) glide crossing with a long rising (or descending) glide. There is a short gap (around 100 ms) in the temporal middle of the cross in the long glide, the gap is yet perceived in the short gap instead of the long glide, by the perceptual integration of onsets and offsets of the sound segments at the crossing ( Nakajima et al, 2000 ; Kanafuka et al, 2007 ). For the visual stimuli, we used a typical Ternus display that is composed of two successive visual frames, each containing two horizontal dots.…”

Perception of visual apparent motion is modulated by a gap within concurrent auditory glides, even when it is illusory

Auditory and visual events often happen concurrently, and how they group together can have a strong effect on what is perceived. We investigated whether/how intra- or cross-modal temporal grouping influenced the perceptual decision of otherwise ambiguous visual apparent motion. To achieve this, we juxtaposed auditory gap transfer illusion with visual Ternus display. The Ternus display involves a multi-element stimulus that can induce either of two different percepts of apparent motion: ‘element motion’ (EM) or ‘group motion’ (GM). In “EM,” the endmost disk is seen as moving back and forth while the middle disk at the central position remains stationary; while in “GM,” both disks appear to move laterally as a whole. The gap transfer illusion refers to the illusory subjective transfer of a short gap (around 100 ms) from the long glide to the short continuous glide when the two glides intercede at the temporal middle point. In our experiments, observers were required to make a perceptual discrimination of Ternus motion in the presence of concurrent auditory glides (with or without a gap inside). Results showed that a gap within a short glide imposed a remarkable effect on separating visual events, and led to a dominant perception of GM as well. The auditory configuration with gap transfer illusion triggered the same auditory capture effect. Further investigations showed that visual interval which coincided with the gap interval (50–230 ms) in the long glide was perceived to be shorter than that within both the short glide and the ‘gap-transfer’ auditory configurations in the same physical intervals (gaps). The results indicated that auditory temporal perceptual grouping takes priority over the cross-modal interaction in determining the final readout of the visual perception, and the mechanism of selective attention on auditory events also plays a role.
