Interpolated Activity in Short-Term Motor Memory

Abstract
Retention of kinesthetic information from blind positioning responses was examined for 56 Ss. During a 30-sec. retention interval, half of the Ss sat quietly with their hands on the lever; the other half learned an interpolated target which required an antagonistic response. Both conditions showed significant amounts of forgetting. The mean differences between conditions as well as the differences between correlation coefficients across retention intervals were not significant. The results were consistent with memory-trace decay predictions.
