Non reinforcement occurs when the target behavior is exhibited and there is noresponse from the environement. These acts produce neutral results and bringneither rewards nor punishment. However, if an act has been consistentlyfollowed by a reward in the past, but fails to elicit the expected reward,frustration occurs. If many repetitions of the act fail to result in theexpected reward, the act will grow less and less frequent and will eventually,become extinguished.
