The present study examines wether self-controlled practice enhances motor learning and self-efficacy beliefs more when it refers to an aspect of the learning situation which is preferred by the learner than to an aspect which is not. Participants (N = 52) practiced the forhand top spin stroke in table tennis and were randomly assigned to one of four groups. Two groups of learners (self-control)...

It is well established that an effective way to schedule knowledge of results (KR) during practice to facilitate motor learning is to allow the learner to control their KR delivery, termed self-controlled KR, rather than imposing the same schedule on the learner without choice, termed yoked KR. The learning advantages of self-controlled KR schedules have been attributed to motivational influenc...

the purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor kr) groups. they practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respec...

This paper examines whether self-controlled feedback schedules enhance learning, because they are more tailored to the performers' needs than externally controlled feedback schedules. Participants practiced a sequential timing task. One group of learners (self-control) was provided with feedback whenever they requested it, whereas another group (yoked) had no influence on the feedback schedule....

Self-rostering is receiving more and more attention in literature and in practice. With self-rostering, employees propose the schedule they prefer to work during a given planning horizon. However, these schedules often do not match with the staffing demand as specified by the organization. We present an approach to support creating feasible schedules that uses the schedules proposed by the empl...
