It's not just N=24 because those same participants took 9 independent tests which generates more data. Also, the p-value should be considered along with the N, since the sampling variance of the test statistic will go up with a small N and this is accounted for in the test thresholds, which somewhat offsets that limitation.

But, a larger N and replication studies are needed.

Good points, one question - did you mean to say "6 independent tests", or am I missing something?

I thought it was 9, but I might have misread the study.
