We used a brain "pinging" again and found that distractor suppression is reactive rather than proactive, meaning attention is first drawn to the distractor before being suppressed.

Neural mechanisms of learned suppression uncovered by probing the hidden attentional priority map

Learned suppression of distractor locations in visual search emerges through reactive mechanisms that involve initial spatial selection prior to suppression.

New preprint by Michael Wolff and me, on accelerating visual perception! The perception of an image can be accelerated by another before it. But how does this happen in the brain? Michael developed a new method to quantify the temporal shift across time in EEG. 1/3 www.biorxiv.org/content/10.1...

Variable processing shifts during perceptual acceleration: Evidence from temporal integration

The perception of a stimulus can be accelerated by another that precedes it. Research to date has focused on quantifying this acceleration, and localizing it in the chain of perceptual and cognitive processes that are involved. This is challenging, because these processes may interact unexpectedly, and because traditional (univariate) analyses of brain activity and behaviour may conflate processes with the representations they act on. By using multivariate pattern analysis of EEG data from a missing element task, designed to measure the visual temporal integration of two successive stimulus displays, we were able to track the representation associated with the integrated percept. We manipulated the delay between our displays, and observed commensurate acceleration of the resultant integrated representation. Furthermore, regardless of the delay, we found that although processing was already accelerated during the earliest processing stages at around 100ms after stimulus onset, intermediate stages, at around 200ms, were even more accelerated. In contrast, later processing stages, at around 400ms, again showed less acceleration. The results thus suggest that perceptual acceleration during temporal integration is nonlinear, and that some time that is gained at one moment in the process can be lost again at another. ### Competing Interest Statement The authors have declared no competing interest.
