Many people actually have difficulty in distinguishing between left and right, and according to a recent report, some of those people may work in the medical profession. Pennsylvania residents may have heard of cases of medical malpractice in which an individual had the wrong limb amputated or surgery performed on the wrong side of the body.
Although distinguishing left from right might come almost automatically for some people, doing so is actually part of a neurologically complex process. Furthermore, distraction can make it even more difficult. In a study that appeared in one journal, researchers tested 234 medical students on how well they could tell right from left with the distraction of noise resembling that of a busy hospital ward.
