Kinesthetic Recall And Information Bold>Reduction Activity

2 experiments are reported in which interpolated motor activity requiring either information reduction (1.86 bits) or no reduction was compared to a control to examine their effects on kinesthetic retention. Exp. 1 used an independent groups design and found only absolute error to increase over the delay intervals. Information reduction activity did not affect kinesthetic retention and there was increasing negative error for longer movements, with positive response sets for short movements and negative response sets for long movements. Exp. 2 replicated the retention interval conditions using a within-Ss design. No difference between conditions was found for either absolute or algebraic error, but an effect of Retention Intervals was found for absolute error. For both studies, the Interpolated Activity X Retention Interval interaction failed significance. No evidence was found to support interference or available processing capacity expalanation for the loss of retention.
