Tactile motion biases visual motion perception in binocular rivalry

Abstract: There is an ongoing debate whether or not multisensory interactions require awareness of the sensory signals. Static visual and tactile stimuli have been shown to influence each other even in the absence of visual awareness. However, it is unclear if this finding generalizes to dynamic contexts. In the present study, we presented visual and tactile motion stimuli and induced fluctuations of visual awareness by means of binocular rivalry: two gratings which drifted in opposite directions were displayed, one to … Show more

“…Our finding of a relatively weak link between visual and tactile locations in the case of modality-specific attention stands in marked contrast to findings indicating that visual and tactile texture (Lunghi, Binda, & Morrone, 2010) and motion (Hense, Badde, & Röder, 2019) information are even integrated in the absence of awareness. This contrast suggests that prior assumptions about the shared origin of visual and tactile signals depend on the feature in question, again pointing toward flexible rather than rigid priors about the relation between visual and tactile signals.…”

“…We suggest the visual and rotation signals are combined and alter the relative strength between the two competing visual signals. This squares with recent multisensory studies of binocular rivalry ( Conrad et al., 2010 ; Hense et al., 2019 ; Lunghi et al., 2014 ) showing that congruent crossmodal stimuli modulate binocular rivalry alternations. These crossmodal influences can be tightly tuned for feature congruence ( Lunghi and Alais, 2013 ; Lunghi et al., 2014 ) and can modulate rivalry by both extending rivalry phases when the crossmodal stimulus is congruent with dominant visual stimulus and shortening rivalry phases when it is not, thereby hastening the re-emergence of the suppressed (but congruent) image ( Lunghi and Alais, 2015 ).…”

“…When a cross-modal stimulus congruent with one of the rivaling images causes perception to dwell on the congruent image, it indicates a clear and selective multisensory interaction. This paradigm has previously revealed tuned auditory ( Conrad et al., 2010 ; Lunghi et al., 2014 ) and tactile ( Hense et al., 2019 ; Lunghi et al., 2014 ; Lunghi and Alais, 2015 ) modulation of vision. For example, touching a tactile grating that is oriented to match one of a pair of rivaling visual gratings causes the matched grating to remain visible longer when it is perceptually dominant, in addition to shortening its suppression duration when suppressed ( Lunghi and Alais, 2013 ).…”

“…Lunghi and colleagues previously used oriented haptic gratings to demonstrate that tactile input congruent with one of the rivalling gratings could influence rivalry dynamics when the haptic and visual stimuli were congruent in orientation, tightly matched in spatial frequency and spatially aligned (Lunghi & Alais, 2015;van der Groen et al, 2013). A similar effect has been observed for translational motion signals: congruent tactile motion promoted the dominance duration of the matching visual stimulus and shortened its periods of suppression, supporting an early interaction across modalities (Hense et al, 2019).…”

“…We also examined if visuo-tactile interactions would still occur when tactile motion was presented to spatially misaligned visual stimuli. Furthermore, most visuo-tactile studies that have utilised the rivalry paradigm have so far done so without visual feedback – participants were unable to see their stimulated hand (Hense et al, 2019 ; Lunghi & Alais, 2013 ; Lunghi & Morrone, 2013 ). Given that vision and somatosensation are closely linked to proprioception, it remains to be seen if hand visibility could facilitate visuo-tactile interactions by serving as an ecological cue within peripersonal space.…”
