Motor effects on confidence judgements

Confidence ratings often correlate (negatively) with reaction times. This, intuitively, makes sense: we're probably more sure when we respond quickly, and less sure when we have to think about an answer. We asked whether this is just a correlational effect or a causal one.

As far as our results show, it's just a correlational effect: when we used a "no-report" paradigm to remove, and bypass, first-order responses, there were no changes in either confidence or metacognitive sensitivity.

We work on this project together with Nathan Faivre.
