Withdrawn StatementThe authors have withdrawn this manuscript because we detected fundamental errors in the formula we used to convert eye tracking data (x and y coordinates) from pixels to degrees. After addressing these errors, the results changed considerably. On the one hand, the behavioral results point towards differences for the bullseye versus the standard fixation cross different and larger than originally reported. However, the eyetracking decoding difference between standard and bullseye fixation cross is no longer significant. Therefore, the main claim of the paper - that bullseye fixation cross leads to lower eye movements compared to standard fixation cross, in turn resulting in lower decoding performance of object identity for eyetracking and EEG data - no longer stands. Given this change in the main results, we therefore withdraw the preprint.. Therefore, the authors do not wish this work to be cited as reference for the project.
