The terms negative and positive feedback can be used loosely or colloquially to describe or imply [[criticism]] and [[praise]], respectively. This may lead to confusion with the more technically accurate terms positive and negative reinforcement, which refer to something that changes the likelihood of a future [[behaviour]].

Negative feedback was applied by [http://en.wikipedia.org/wiki/Harold_Stephen_Black Harold Stephen Black] to electrical amplifiers in 1927, but he could not get his idea patented until 1937.[2] [http://en.wikipedia.org/wiki/Arturo_Rosenblueth Arturo Rosenblueth], a Mexican researcher and physician, co-authored a seminal 1943 paper ''Behavior, Purpose and Teleology''[3] that, according to Norbert Wiener (another co-author of the paper), set the basis for the new science cybernetics. Rosenblueth proposed that behaviour controlled by negative feedback, whether in [[animal]],  or [[machine]], was a determinative, directive principle in [[nature]] and human [[creations]].[citation needed]. This kind of feedback is studied in cybernetics and control theory.[http://en.wikipedia.org/wiki/Feedback]
