Revision as of 09:13, 1 October 2015 by 108.162.219.165 (talk) (Rats pull levers for many reasons...)
Is the "rat pulling a lever" phrase a reference to studies with rats where they will self administer opiates and ignore food until death? http://en.wikipedia.org/wiki/Brain_stimulation_reward#Addiction 108.162.219.46 23:39, 20 March 2014 (UTC)
"Rat pulling a lever" studies are done to test a wide variety of hypotheses about behavior, not just how they respond to opiates. Rats are one of the favorite animals used in psychological studies, especially among doctoral candidates working on their dissertations. 108.162.219.165 09:13, 1 October 2015 (UTC)
