title: The post-kr interval.
abstract: The effect of a filled or unfilled post-KR interval during the acquisition phase of learning a blind positioning task was examined. The post-KR interval was either 2 or 30 sec., and was either unfilled or filled with a motor or verbal interpolated task. Ss were required to reach a learning criterion of three consecutive correct responses in positioning the arm to a 75 ± 2 deg. criterion using a Kinesthesiometer while blindfolded. There was no effect on performance of either Length of the post-KR interval or Activity during the interval, but females performed significantly better than males. The results were discussed in terms of the relationship of motor STM theory to the acquisition process of learning a motor skill.
