The Post Knowledge of Results Interval: Effects of Interpolated Activity on Cognitive Information Processing

Abstract

The present study investigated the effects of interpolated activity on the cognitive information processing operations occurring during the post knowledge of results (KR) interval. Eighty right-handed subjects were randomly assigned to four post-KR interval activity groups and required to complete the McCloy blocks test of multiple response to a criterion of three consecutive errorless trials in less than 35 sec each. The four post-KR intervals included: (1) interfering verbal cognitive activity, (2) attention-demanding verbal activity, (3) attention-demanding motor activity, or (4) rest. Orthogonal planned comparisons indicated that the post-KR interval activity groups differed from the rest group on the acquisition of the criterion task. Comparisons of verbal versus motor, and of interfering verbal cognitive versus attention-demanding verbal activities revealed no significant findings. Additional findings indicated no significant relationship between criterion and interpolated activity performance. Discussion centered on the role of KR in hypothesis selection and evaluation during the post-KR interval, and on the debilitating effects of interpolated activity on this process.     

Post-Knowledge of Results Delay: Effects of Interpolated Activity on Learning and Performance

Abstract

The present experiment investigated the effects of interpolated processing activity (IPA) during the post knowledge of results (KR) interval. The study attempted to correct some of the problems inherent in previous research by using a ballistic timing criterion task and assessing the effects of interpolated processing activity (IPA) on both acquisition and No KR transfer trials. To insure that the efficacy of the IPA manipulation, a paced task was used and performance was assessed. Two levels of post-KR delay (5 and 10 s) were factorially combined with two levels of IPA (IPA or No IPA) to yield four experimental groups. Each subject completed 30 KR acquisition trials and 20 No KR transfer trials. Interresponse interval was held constant. In contrast to many previous studies, IPA interfered with the subjects' ability to learn and perform the criterion movement time of 150 ms. Both the memory trace and the perceptual trace were similarly affected. The detrimental effects of IPA on absolute error and objective-subjective error differences found during acquisition persisted during KR withdrawal.
