A test for interaction of delay of knowledge of results and two types of interpolated activity.

Abstract

"This experiment replicates two groups of a line-drawing study by Greenspoon and Foreman, i.e., 0-and 20-sec. delay of knowledge of results. Their data gave evidence of the efficacy of immediate knowledge of results. The present experiment gave null results, the outcome being entirely consistent with a number of earlier studies." The discussion is in terms of the manner in which the hand and arm are maintained between trials and the possible effects of fatigue. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
