This repository contains data of Exp. 3 and supplementary material presented in the paper **Saccadic omission revisited: What saccade-induced smear looks like** by Richard Schweitzer, Mara Doering, Thomas Seel, Jörg Raisch, and Martin Rolfs (doi: https://doi.org/10.1101/2023.03.15.532538). It also contains a markdown document - https://osf.io/bjgqk - with all relevant analyses presented in the paper. Please have a look at the *ANALYSIS* folder for analyses code, cleaned data, supplementary data. For modular, documented examples how to use the code, have a look at https://github.com/richardschweitzer/MotionSmearModelingPlayground. **Background** In a famous, yet never replicated experiment, Campbell & Wurtz (1978) briefly illuminated a laboratory room during saccades, allowing the observers to perceive the smeared visual scene, that should normally be induced on the retina due to the eyes' high angular velocities during saccades. In previous experiments (see [https://osf.io/bf246/][1] and [https://osf.io/ue6cd/][2]) we studied the perception of smeared natural images strictly during the saccade. In this third experiment, we will use subjective reports to measure the extent of intra-saccadic smear, that is, observers will adjust the length and angle of a linear motion filter applied to the (intra-saccadically presented) scene stimulus to match their perception of smear. **References** Campbell, F.
