The effects on skill acquisition of an interpolated motor short-term memory task during the kr-delay interval

The effects of an interpolated motor short-term memory task during the KR-delay interval on skill acquisition was investigated. On each trial subjects estimated two positions on a linear-positioning apparatus. One group of subjects was presented two biasing movements, which they immediately recalled, during the KR-delay interval. The interpolated motor short-term memory task interfered with skill acquisition and retention.
