“…The magnitude of the localization shift is the same for the inhibition and adaptation instruction, whereas secondary saccades occur less frequently following the inhibition instruction ( Heins et al, 2019 ). It thus appears most likely that the efference copy of the saccade is involved in the process of neural recalibration ( Bahcall & Kowler, 1999 , 2000 ; Cavanaugh, Berman, Joiner, & Wurtz, 2016 ; Collins & Wallman, 2012 ; Masselink & Lappe, 2021 ). In addition, our results indicate that the amplitude of the executed saccade does not always reflect this adaptation state, because the localization shift is equally strong for both instructions, whereas the adaptive changes to the saccade amplitude are not.…”

Saccadic eye movements are often imprecise and result in an error between expected and actual retinal target location after the saccade. Repeated experience of this error produces changes in saccade amplitude to reduce the error and concomitant changes in apparent visual location. We investigated the relationship between these two plastic processes in a series of experiments. Following a recent paradigm of inhibition of saccadic adaptation, in which participants are instructed to look at the initial target position and to continue to look at that position even if the target were to move again, our participants nevertheless perceived a visual probe presented near the saccade target to be shifted in direction of the target error. The location percept of the target gradually shifted and diverged over time from the executed saccade. Our findings indicate that changes in perceived location can be the same even when changes in saccade amplitude differ according to instruction and can develop even when the amplitude of the saccades executed during the adaptation procedure does not change. There are two possible explanations for this divergence between the adaptation states of saccade amplitude and perceived location. Either the intrasaccadic target step might trigger updating of the association between pre- and post-saccadic target positions, causing the localization shift, or the saccade motor command adjusts together with the perceived location at a common adaptation site, downstream from which voluntary control is exerted upon the executed eye movement only.

“…For instance, during development, incidental sensory consequences are the beginning of intended movement outcomes as infants learn the utility of their actions 44 . Similarly, intrinsic consequences such as pre-saccadic attention shifts 45 or efference copy signals (copies of motor commands that inform perceptual processing) 46 might adapt to anticipate intended and incidental consequences of movements 47 . We briefly introduce intrinsic and intended consequences before focusing on incidental consequences.…”

“…Instead, post-saccadic feedback is required to make any necessary adjustments to restore or maintain accuracy ( Collins & Wallman, 2012 ; Havermann & Lappe, 2010 ; Noto & Robinson, 2001 ; Wallman & Fuchs, 1998 ; Wong & Shelhamer, 2011 ). The adjustment of saccade amplitude, also termed saccade adaptation, is based on a comparison of the expected and actual sensory consequences of the eye movement, from which a motor error is postdicted ( Masselink & Lappe, 2021 ). Saccadic adaptation then aims to minimize this postdicted motor error.…”

Saccadic eye movements bring objects of interest onto our fovea. These gaze shifts are essential for visual perception of our environment and the interaction with the objects within it. They precede our actions and are thus modulated by current goals. It is assumed that saccadic adaptation, a recalibration process that restores saccade accuracy in case of error, is mainly based on an implicit comparison of expected and actual post-saccadic position of the target on the retina. However, there is increasing evidence that task demands modulate saccade adaptation and that errors in task performance may be sufficient to induce changes to saccade amplitude. We investigated if human participants are able to flexibly use different information sources within the post-saccadic visual feedback in task-dependent fashion. Using intra-saccadic manipulation of the visual input, participants were either presented with congruent post-saccadic information, indicating the saccade target unambiguously, or incongruent post-saccadic information, creating conflict between two possible target objects. Using different task instructions, we found that participants were able to modify their saccade behavior such that they achieved the goal of the task. They succeeded in decreasing saccade gain or maintaining it, depending on what was necessary for the task, irrespective of whether the post-saccadic feedback was congruent or incongruent. It appears that action intentions prime task-relevant feature dimensions and thereby facilitated the selection of the relevant information within the post-saccadic image. Thus, participants use post-saccadic feedback flexibly, depending on their intentions and pending actions.
