“…3 that can be due to a stronger prediction of the upcoming stimulus and therefore a stronger phantom percept. Our results are in agreement with recent studies demonstrating the existence of a partial but systematic transsaccadic integration of visual features across saccades 15 – 17 , 19 , 26 , 42 as well as the neural signature of the transsaccadic memory 43 , 44 .…”

Across saccadic eye movements, the visual system receives two successive static images corresponding to the pre- and the postsaccadic projections of the visual field on the retina. The existence of a mechanism integrating the content of these images is today still a matter of debate. Here, we studied the transfer of a visual feature across saccades using a blanking paradigm. Participants moved their eyes to a peripheral grating and discriminated a change in its orientation occurring during the eye movement. The grating was either constantly on the screen or briefly blanked during and after the saccade. Moreover, it either was of the same luminance as the background (i.e., isoluminant) or anisoluminant with respect to it. We found that for anisoluminant gratings, the orientation discrimination across saccades was improved when a blank followed the onset of the eye movement. Such effect was however abolished with isoluminant gratings. Additionally, performance was also improved when an anisoluminant grating presented before the saccade was followed by an isoluminant one. These results demonstrate that a detailed representation of the presaccadic image was transferred across saccades allowing participants to perform better on the transsaccadic orientation task. While such a transfer of visual orientation across saccade is masked in real-life anisoluminant conditions, the use of a blank and of an isoluminant postsaccadic grating allowed to reveal its existence.

“…The FRP N170 effect was of slightly smaller amplitude and longer latency than that of the ERP effect. The longer latency is consistent with the result of a very recent study using face stimuli with FRPs, although that study did not address the face-effect per se as no non-face stimuli were presented (Huber-Huber et al, 2019). In addition, there was no direct comparison to ERPs (ERPs in that study were limited to peripheral stimuli and showed even later N1).…”

“…While the ERP and FRP differential face-effect showed overall similar components and topographies viewing there are changes across of the whole visual field following the eye movement. Second, since the saccade is self-generated (even if cued), free viewing may not only utilize peripheral information to predict the input (Huber-Huber et al, 2019), but also generate precise temporal predictions. These differences might affect components associated with both high and low-level feature processing.…”

“…Some of these studies have directly compared well known ERP components evoked by a stimulus onset to those evoked by fixation onsets, such as the P1 (Kazai & Yagi, 2003), the N400 (Dimigen et al, 2011;Hutzler et al, 2007) and the P3 (Kamienkowski et al, 2012). Other FRP studies have used face images to test effects such as target detection or effects of prediction (Dimigen et al, 2009;Ehinger & Dimigen, 2018;Huber-Huber et al, 2019;Kaunitz et al, 2014), yet did not compare face-selective activity, that is, the difference between the response to faces and other stimuli, between ERPs and FRPs. The careful examination of categorical processing comparing free viewing and static gaze conditions is important for future interpretation of categorical processing and object identification in free-viewing studies.…”

AbstractEvent Related Potentials (ERPs) are widely used to study category-selective EEG responses to visual stimuli, such as the face-selective N170 component. Typically, this is done by flashing stimuli abruptly at the point of static gaze fixation. While allowing for good experimental control, these paradigms ignore the dynamic role of eye-movements in natural vision. Fixation-related potentials (FRPs) obtained using simultaneous EEG and eye-tracking, overcome this limitation. Various studies have used FRPs to study processes such as lexical processing, target detection and attention allocation. The goal of this study was to compare face-sensitive activity evoked by stimulus abrupt appearance with that evoked by self-controlled gaze fixations on a stimulus. Twelve participants were studied in three experimental conditions: Free-viewing (FRPs), Cued-viewing (FRPs) and Control (ERPs). We used a multiple regression approach to disentangle overlapping activity components. Our results show that the N170 face effect (face vs. non-face) is evident for the first fixation on a stimulus, whether it follows a self-generated saccade or stimulus appearance at fixation point. Furthermore, the N170 exhibits category-specific adaptation in free viewing. The N170 face effect had similar topography across viewing conditions, but there were major differences within each stimulus category. We ascribe these differences to an overlap of the fixation-related Lambda response and the N170. We tested the plausibility of this account using dipole simulations. This study establishes the use of the N170 face effect as a signature of face detection in free-viewing experiments while highlighting the importance of accounting for eye-movement related effects.

“…Neurophysiology studies with monkey subjects showed latencies in this order (30-50 ms) to spatial frequencies in the superior colliculus (Mazer et al, 2002;Chen et al, 2018a). This rapid postsaccadic response would allow for the read-out of visual information significantly earlier than expected based on previous trans-saccadic studies measuring high-level visual information about object identity or category, which showed time scales well over 100 ms (Edwards et al, 2018;Huber-Huber et al, 2019). High-level visual information, such as facial identity, is represented by neurons with large receptive fields and requires more time to process than SF.…”
