New preprint on covert shift of attention and inhibition
We have a new preprint on bioRxiv titled: “Time-locked inhibition of covert orienting” were we look at inhibitory processes during covert orienting in the absence of saccades.
In this project, we were interested to study if a similar phenomenon of the well-known Saccadic Inhibition (Reingold & Stampe, 2002; Buonocore & McIntosh, 2008) can also affect covert orienting and consequently altering visual discrimination. To do so, we combined a classic task for the exogenous cueing of covert attention (Posner, 1980) with a saccadic inhibition paradigm (Buonocore et al., 2017), to create a novel covert orienting task suitable for testing the inhibitory influence of an irrelevant visual transient.
Interestingly, we find a SI-like time-specific covert inhibition effect in which the irrelevant flash impaired orientation discrimination accuracy only when the cue preceded the probe by about 200 ms.
