I thought it was intesting that WT mentioned this type of experiment as I'd only recently given Vic a clip (Lovely Word clip!), albeit totally undeserved, when I failed to see his subtle sarcasm. Masserman's observations are still used today in psychiatry as he was one of the first, and probably the most widely acknwledged, within the field of empathy research. Up until he started his research it was widely believed that empathy was the main distinguishing factor between animals and humans but his findings proved otherwise while at the same time giving a degree of support to the theory that humans have evolved from primates.
