I remember it differently. They react about the same to any kind of stimulus as "normal" people but recover faster. Also when the experimenters set it up so that they can expect pain after a certain cue, they do not freak themselves out. Normal people actually feel part of the pain, after the cue, before the actual pain, but highly experienced meditators don't, they just feel the pain when it arrives. But yeah I occasionally meditate and it helps.
