**Predictions** 1. If intra-saccadic motion streaks facilitate object localization across saccades, then a behavioral processing benefit – that is, a shorter secondary saccade latency – should be observed in streak-present conditions. As the duration of the intra-saccadic signal is 25 ms, we expect the secondary saccade latency effect to be much smaller than that duration. 2. In streak-present conditions, we predict an earlier and enhanced post-saccadic classification accuracy of the target's movement direction (similar to Edwards et al., 2018), as the intra-saccadic streak might act as a cue to the (unpredictable) post-saccadic object location and thus inform the secondary saccade even while the primary saccade is still ongoing. In addition, we expect the classifier to strongly rely on occipital electrodes (based on absolute weights of SVM), as the earliest post-saccadic visual potentials, such as the lambda wave, have an occipital topography. 3. If the streak has a functional value, then we expect that it should be possible to decode it at a very early time point, probably at around 100 ms after saccade offset (or even before that) and necessarily before the onset of the secondary saccade. Furthermore, we expect a positive correlation between secondary saccade latency and the latency of the visual response decoded from the EEG data. 4. We expect large differences between movement directions. While target movements orthogonal to the direction of the saccade are likely to be salient as they are known to break saccadic suppression of displacement (Wexler & Collins, 2014), those movements parallel to saccade direction are likely to suffer from the latter. We predict that decoding accuracy of the streak present/absent class for parallel target movements will be lower than for orthogonal target movements. Similar differences might be found for secondary saccade latencies. **References** Edwards, G., VanRullen, R., & Cavanagh, P. (2018). Decoding trans-saccadic memory.
