“…Interestingly, we found that not only can adaptation aftereffects be measured in both retinotopic and world-centered coordinates, but these aftereffects also can exist independently: when only a single retinotopic but multiple-screen coordinates or a single-screen region and multiple retinal locations were being adapted. This finding is consistent with previous work showing that aftereffects can be found in multiple reference frames ( Hisakata & Kaneko, 2019 ; Lauffs, Choung, Ogmen, Herzog, & Kerzel, 2019 ; Ogmen & Herzog, 2010 ; Peñaloza, Herzog, & Öğmen, 2020 ). The finding also suggests that the distance between two objects could depend on different, possibly separate mechanisms: an early representation residing in retinotopic maps and another higher level encoded in world-centered coordinates.…”

Exposure to a dynamic texture reduces the perceived separation between objects, altering the mapping between physical relations in the environment and their neural representations. Here we investigated the spatial tuning and spatial frame of reference of this aftereffect to understand the stage(s) of processing where adaptation-induced changes occur. In Experiment 1, we measured apparent separation at different positions relative to the adapted area, revealing a strong but tightly tuned compression effect. We next tested the spatial frame of reference of the effect, either by introducing a gaze shift between adaptation and test phase (Experiment 2) or by decoupling the spatial selectivity of adaptation in retinotopic and world-centered coordinates (Experiment 3). Results across the two experiments indicated that both retinotopic and world-centered adaptation effects can occur independently. Spatial attention to the location of the adaptor alone could not account for the world-centered transfer we observed, and retinotopic adaptation did not transfer to world-centered coordinates after a saccade (Experiment 4). Finally, we found that aftereffects in different reference frames have a similar, narrow spatial tuning profile (Experiment 5). Together, our results suggest that the neural representation of local separation resides early in the visual cortex, but it can also be modulated by activity in higher visual areas.

“…In the object appeared static behind the occluder (dynamic occluder, static shape). In this case, elements of the shape remained within a static reference frame, which guides the attribution of stimulus features according to group identity (Lauffs et al, 2019). One could argue that the preserved retinotopic correspondences within the static reference frame allowed symmetry perception.…”

“…Within the short temporal scale (around 300 ms), the within-frame grouping corresponds to retinotopic processing, whereas the between-frames grouping mainly adopts nonretinotopic processing ( Thunell et al. 2016 ; Lauffs et al. 2019 ).…”

Microsaccadic Eye Movements but not Pupillary Dilation Response Characterizes the Crossmodal Freezing Effect

In typical spatial orienting tasks, the perception of crossmodal (e.g., audiovisual) stimuli evokes greater pupil dilation and microsaccade inhibition than unisensory stimuli (e.g., visual). The characteristic pupil dilation and microsaccade inhibition has been observed in response to ‘salient’ events/stimuli. While the ‘saliency’ account is appealing in the spatial domain, whether this occurs in the temporal context remains largely unknown. Here, in a brief temporal scale (within 1 second) and with the working mechanism of involuntary temporal attention, we investigated how eye metric characteristics reflect the temporal dynamics of perceptual organization, with and without multisensory integration. We adopted the crossmodal freezing paradigm using the classical Ternus apparent motion. Results showed that synchronous beeps biased the perceptual report for group motion and triggered the prolonged sound-induced oculomotor inhibition (OMI), whereas the sound-induced OMI was not obvious in a crossmodal task-free scenario (visual localization without audiovisual integration). A general pupil dilation response was observed in the presence of sounds in both visual Ternus motion categorization and visual localization tasks. This study provides the first empirical account of crossmodal integration by capturing microsaccades within a brief temporal scale; OMI but not pupillary dilation response characterizes task-specific audiovisual integration (shown by the crossmodal freezing effect).
