Abstract : Research on schematic concept formation (SCF) using VARGUS 7 patterns at high redundancy levels has indicated that 0% and 100% knowledge of results (KOR) does not differentially affect task performance. An experiment to determine the effect of 0%, 25%, 50%, 75%, and 100% KOR in the SCF task indicated that SCF occurred but was not differentially affected by the KOR variable. The subject's certainty of the correctness of his responses was reliably higher for correct than for incorrect responses, but was not reliably influenced by the KOR variable. These data, and earlier studies, indicate that KOR does not facilitate concept formation when the high redundancy VARGUS 7 patterns are used. There is some evidence in this study that intermediate levels of KOR may interfere with SCF. (Author)
