Size Perception of a Sport Target as a Function of Practice Success Conditions.

Superior motor task success has been correlated with participants' self-reports of a larger-than-actual size of a sport-related target. In the present study, we examined whether a putting practice condition with greater success would differentially impact participants' self-reported perceptions of the size of the putting hole during acquisition and retention. We randomly assigned participants to one of three different practice conditions (success-early, success-late, and self-controlled success) and had them self-report their perceived size of the putting hole upon completion of each required putting distance (25, 50, 75, 100, 125, 150, 175, 200 cm).

On Whether Task Experience of the Peer Differentially Impacts Feedback Scheduling and Skill Acquisition of a Learner.

Previous research has shown that peers without task experience provided knowledge of results (KR) as effectively as performers who self-controlled their own KR schedule (McRae et al., 2015). In the present experiment, a group of participants first practiced a motor task while self-controlling their KR during a defined acquisition period.

Examining changes in corticospinal excitability and balance performance in response to social-comparative feedback.

Background: Social-comparative feedback informs an individual that their performance was better or worse than the group. Previous studies have found that compared to knowledge of results alone, social-comparative feedback produces a valence response that results in larger improvements in balance performance. However, the neural processes contributing to these motor improvements have not yet been examined.

Accuracy of Subjective Performance Appraisal is Not Modulated by the Method Used by the Learner During Motor Skill Acquisition.

The present experiment examined whether the method of subjectively appraising motor performance during skill acquisition would differentially strengthen performance appraisal capabilities and subsequent motor learning. Thirty-six participants (18 men and 18 women; M age = 20.8 years, SD = 1.

Measuring Investment in Learning: Can Electrocardiogram Provide an Indication of Cognitive Effort During Learning?

Heart rate variability (i.e., low frequency:high frequency ratio) was measured to differentiate invested cognitive effort during the acquisition and retention of a novel task.

Examining the Preferred Self-Controlled KR Schedules of Learners and Peers During Motor Skill Learning.

In many practical situations, learners are provided with feedback in the form of knowledge of results (KR) by a peer. However, when peers provide KR is currently unknown. When given the opportunity to request KR in a self-controlled manner, some participants have reported a preference for requesting KR after good performances.

The influence of instruction on arm reactions in individuals with Parkinson's disease.

The purpose of this study was to examine whether explicit instruction would facilitate arm reactions in individuals with Parkinson's disease (PD). Individuals with (n = 10) and without (n = 15) PD responded to unexpected support-surface translations. To recover their balance, participants were required to either respond naturally (react natural) or to reach toward a nearby handrail (explicit instruction).

Learning effects of self-controlled practice scheduling for children and adults: are the advantages different?

The benefit of providing learners control over their repetition schedule during multi-task learning has been limited to adult samples. Recently, differences in self-controlled strategies, such as frequent requests for knowledge of results by children (10 years) compared to adults have been reported. The purpose of the present experiment was to assess the benefits of a self-controlled repetition schedule during multi-task learning for children compared to adults.

Self-controlled KR schedules: does repetition order matter?

The impact of an experimenter-defined repetition schedule on the utility of a self-controlled KR context during motor skill acquisition was examined. Participants were required to learn three novel spatial-temporal tasks in either a random or blocked repetition schedule with or without the opportunity to control their KR. Results from the retention period showed that participants provided control over their KR schedule in a random repetition schedule demonstrated superior learning.

Understanding Self-Controlled Motor Learning Protocols through the Self-Determination Theory.

The purpose of the present review was to provide a theoretical understanding of the learning advantages underlying a self-controlled practice context through the tenets of the self-determination theory (SDT). Three micro-theories within the macro-theory of SDT (Basic psychological needs theory, Cognitive Evaluation Theory, and Organismic Integration Theory) are used as a framework for examining the current self-controlled motor learning literature. A review of 26 peer-reviewed, empirical studies from the motor learning and medical training literature revealed an important limitation of the self-controlled research in motor learning: that the effects of motivation have been assumed rather than quantified.

Self-controlled knowledge of results: age-related differences in motor learning, strategies, and error detection.

Research has demonstrated that a self-controlled KR schedule is advantageous for motor learning; however, the usefulness of a self-controlled KR context in older adults remains unknown. To address this gap in knowledge, we examined whether (1) the learning benefits of a self-controlled KR schedule are modulated by the age of the learner; (2) practicing in a self-controlled KR context concurrently strengthens the learner's error detection mechanism, and (3) the KR strategy during acquisition changes as a function of practice trials completed and age. As a function of age, participants were quasirandomly assigned to either the self-control or yoked group resulting in four experimental groups (Self-Young, Yoked-Young, Self-Old, and Yoked-Old).

Knowing the good from the bad: does being aware of KR content matter?

Previous researchers have suggested that providing KR based on only successful (i.e., good trials) trials enhances learning compared to providing KR on unsuccessful trials (i.

Decreasing the proportion of self-control trials during the acquisition period does not compromise the learning advantages in a self-controlled context.

The present experiment examined the learning effects of participants self-controlling their receipt of knowledge of results (KR) on all or half of their acquisition trials (50%). For participants who were provided 50% self-control, the first half of their acquisition period consisted of receiving KR on all trials, or according to a faded-KR schedule. Participants practiced a sequential timing task.

Self-control of feedback during motor learning: accounting for the absolute amount of feedback using a yoked group with self-control over feedback.

A traditional control group yoked to a group that self-controls their reception of feedback receives feedback in the same relative and absolute manner. This traditional control group typically does not learn the task as well as the self-control group. Although the groups are matched for the amount of feedback they receive, the information is provided on trials in which the individual may not request feedback if he or she were provided the opportunity.

Self-regulated frequency of augmented information in skill learning.

The authors examined the effects of self-regulating task information, identical in content, either before (proactive) or after (retroactive) a motor action. Participants were required to learn unique typographical script used to enter data into a personal data assistant. Consistent with previous findings, presenting task information proactively during acquisition facilitated performance, but presenting task information retroactively resulted in superior learning as measured in retention tests.

Learner regulated knowledge of results during the acquisition of multiple timing goals.

The purpose of the present experiment was to examine the advantages of a learner controlled KR schedule during the acquisition of three novel sequential timing tasks. The self-regulated group requested KR when necessary during the acquisition period while participants in the yoked condition replicated the KR schedule of a self-regulated counterpart, without the choice. The self-regulated condition demonstrated superior performance in retention and transfer, with a relative KR frequency similar for all three sequences.

Examining the proactive and retroactive placement of augmented information for learning a novel computer alphabet.

The timing of augmented information, either prior to or following a memory retrieval attempt has profound, and opposing, influences on immediate performance and retention. This effect was investigated in 2 experiments in which participants learned typographical symbols used to enter information into a personal data assistant. The effects of the spacing of the second of 2 repetitions (Experiment 1) and the number of retrieval attempts during practice (Experiment 2) failed to modify the relative effectiveness of the timing of augmented information--proactive information (prior to retrieval attempt) facilitated practice but degraded retention relative to retroactive information (after retrieval attempt).

Learning a new human-computer alphabet: the role of similarity and practice.

Two purposes motivated this study: (a) to quantify the difficulty in learning various symbols of the alphabet used to enter data into a personal digital assistant (PDA), and (b) to investigate the interaction of item difficulty with practice conditions that promote varying levels of cognitive effort. Levels of compatibility between members of the PDA alphabet and English were quantified through introspective ratings in Experiment 1 and objective performance measures in Experiment 2. Three levels of item compatibility were learned under conditions of proactive or retroactive augmented information in Experiment 3.
