Mean RTs in insight and analytical solvers during the 1^st block of training and the last practice block. While there was no difference in the mean RTs to find the solution number during the 1^st block of training session, insight solvers showed a collapse in RTs when using the hidden rule strategy compared to analytical strategy. Noteworthy, the final block corresponds to the verification block of practice for insight solvers, while it was the last (i.e. 10^th) retest block for analytical solvers.
