And then they looked only at the pictures in the MRI they supposed indicated more cognitive function, and ignored task performance.
- riedel 4y agoHopefully closing the mouth does not affect the postprocessing algorithm of the MRI software (remember tons of fMRI studies invalid due to software artifacts [1]). I guess it really far to easy to generate such results, but difficult to really validate them.

- notahacker 4y agoThey did look at task performance, it's just the oral breathing being marginally quicker and marginally less accurate wasn't statistically significant. If there's no difference in task performance, an alternative explanation is that for the nasal breathing test participants wasted cognitive cycles on remembering to keep their mouth closed (versus oral breathing participants who had their nose plugged)...
