Previous experimentation has yielded contradictory results regarding the effects of delay of knowledge of results (KR) on the acquisition of a simple motor skill. The present experiment used 3 KR conditions: immediate KR, 30-sec. delay of KR, and no KR in a simple line-drawing task. The results confirmed the previous conclusion of Greenspoon and Foreman that delay of KR interferes with the acquisition of a line-drawing response.
