Training can enhance unconscious response priming on fast trials even when measuring consciousness on a trial-by-trial basis.

ABSTRACT: Measuring awareness on a trial-by-trial basis might impose a multi-task cost on the observed effect. Here, we examined this potential cost, asking if it can be mitigated by training. In two experiments, one group of participants reported awareness offline, in a post-test, and another reported it online, in each trial. To test the effect of training, all participants completed two sessions on separate days. When analyzing all trials, we found overall slower reaction times (RTs) in the online group, suggesting a multi-task cost, but no interaction with the priming effect. Notably, this difference was smaller in the second session, implying that the multi-task cost is reduced by training. Critically however, this analysis yielded no convincing evidence for unconscious priming (due to potentia
