EFFECTS OF KNOWLEDGE OF RESULTS AND DIFFERENTIAL MONETARY REWARD ON SIX UNINTERRUPTED HOURS OF MONITORING
Abstract
The effects of knowledge of results (KR) and monetary reward on six hours of uninterrupted monitoring of a complex visual display were examined. Comparisons were made among groups receiving: no KR about response adequacy, KR, KR plus monetary reward or penalty determined by response adequacy, and KR plus reward in practice but not during the criterion session. In addition, comparison was made between the no-KR group and a similar one run by Webber and Adams (1), where a rest had been given after three hours of a six-hour monitoring period. All groups showed performance decrements of small magnitude. The manipulation of KR and reward failed to deter decrement; however, reward in addition to KR did enhance overall performance. KR alone did not facilitate performance, contrary to results from other studies. Training under KR plus reward did not enhance criterion performance when no KR or reward was provided. In support of previous research, man's monitoring capabilities over extended time periods seem adequate for modern systems.
