Overall, our findings showed close connection of the perception of synchrony of the self with both internal (i.e., body and cognition) and external (i.e., others, environment/nature) synchrony being associated positively with adaptive and negatively with maladaptive traits of self. Moreover, we have demonstrated how external (i.e., life events like the COVID-19 pandemic) variables modulate the perception of the self’s internal-external synchrony.

Independently of spatial cueing, repulsion was reduced when the flanker preceded the target by 100 ms compared with when they appeared simultaneously. We confirmed that the preceding flanker quickened the awareness of a nearby target relative to distant ones by 40 ms.

In order to predict the precision of its predictions, the brain has to infer the reliability of its own beliefs. This means that our brains have to recognise the precision of their predictions or, at least, their accuracy. In this paper, we argue that <em>fluency</em> is product of this recognition process. In short, to recognise fluency is to infer that we have a precise ‘grip’ on the unfolding processes that generate our sensations. More specifically, we propose that it is changes in fluency — from unfelt to felt — that are both recognised and realised when updating predictions about precision. <em>Unfelt fluency</em> orients attention to unpredicted sensations, while <em>felt fluency</em> supervenes on—and contextualises—unfelt fluency; thereby rendering certain attentional processes, phenomenologically opaque. As such, fluency underwrites the precision we place in our predictions and therefore acts upon our perceptual inferences.
