Thanks Mike. I'll definitely have to check into these additional resources. I read the Scientific American summary of the research by the authors and the results he said he found was that the monkeys who knew when the shocks were coming and who could do something to avoid them got MORE ulcers than the monkeys who were yoked to them and could do nothing to avoid the shocks. I thought the results were the other way around. Perhaps future researchers discovered this (or were unable to replicate as you suggest below). MOre investigation needed apparently.
