<p>Dataset relative to the following publication:</p> <p>Braun, D. I., Schütz, A. C., & Gegenfurtner, K. R. (2017). Visual sensitivity for luminance and chromatic stimuli during the execution of smooth pursuit and saccadic eye movements. Vision Research</p>
Execution of saccadic eye movements affects speed perception
<p>This depository contains the data from different experiments regarding the perceived speed of moving targets tracked with different oculomotor behavior.</p> <p>The folders "Gap Paradigm" and "Step Paradigm" contain the main data for the manuscript. The folders "Vertical Offset Control" and "Awareness of Saccades" data from additional control experiments.</p> <p>In the folders "Gap Paradigm" and "Step Paradigm" you will find additional folders seperating the conditions for the collected data. One "Pilot" Folder contains the data used in the pilot experiment to determine the relevant eye crossing times. The "Speed Discrimination" Folder contains the files where participants made judgements about moving objects while tracking it with the eyes. In the "Fixation" folder you find the data for the fixation control where observes saw the same stimulus as during the speed discrimination task, but where not allowed to track the moving object.</p> <p>For each of the experiments we have a folder for the seperate blocks of the participant, which contains a logfile which specifys the parameters used for all trials and seperate files which contain information about the eye position during each trial.</p> <p>The structure of the eye position files is always the same: time, x-position, y-position, events marked by the eyelink. The x- and y-position are coded in pixels on the screen. The parameters specified in the log-fileare explained in an additional readme file.</p>
Saccades Exert Spatial Control of Motion Processing for Smooth Pursuit Eye Movements
<p>Saccades modulate the relationship between visual motion and smooth eye movement. Before a saccade, pursuit eye movements reflect a vector average of motion across the visual field. After a saccade, pursuit primarily reflects the motion of the target closest to the endpoint of the saccade. We tested the hypothesis that the saccade produces a spatial weighting of motion around the endpoint of the saccade. Using a moving pursuit stimulus that stepped to a new spatial location just before a targeting saccade, we controlled the distance between the endpoint of the saccade and the position of the moving target. We demonstrate that the smooth eye velocity following the targeting saccade weights the presaccadic visual motion inputs by the distance from their location in space to the endpoint of the saccade, defining the extent of a spatiotemporal filter for driving the eyes. The center of the filter is located at the endpoint of the saccade in space, not at the position of the fovea. The filter is stable in the face of a distracter target, is present for saccades to stationary and moving targets, and affects both the speed and direction of the postsaccadic eye movement. The spatial filter can explain the target-selecting gain change in postsaccadic pursuit, and has intriguing parallels to the process by which perceptual decisions about a restricted region of space are enhanced by attention. The effect of the spatial saccade plan on the pursuit response to a given retinal motion describes the dynamics of a coordinate transformation.</p>

Fast saccadic eye-movements in humans suggest that numerosity perception is automatic and direct.
<p><span>Fast saccades are rapid automatic oculomotor responses to salient and ecologically important visual stimuli such as animals and faces. Discriminating the number of friends, foe or prey may also have an evolutionary advantage. In this study participants were asked to saccade rapidly towards the more numerous of two arrays. Participants could discriminate numerosities with high accuracy and great speed, as fast as 190 ms. Intermediate numerosities were more likely to elicit fast saccades than very low or very high numerosities. Reaction-times for vocal responses (collected in a separate experiment) were slower, did not depend on numerical range, and correlated only with the slow, not the fast saccades, pointing to different systems. The short saccadic-reaction times we observe are surprising given that discrimination using numerosity estimation is thought to require a relatively complex neural circuit, with several relays of information through parietal and pre-frontal cortex. Our results suggest that fast numerosity-driven saccades may be generated on a single feed-forward pass of information recruiting a primitive system that cuts through the cortical hierarchy and rapidly transforms the numerosity information into a saccade command.</span></p>
