The Specificity of Motor Skill and Manual Asymmetry: A Review of the Evidence and Its Implications

Results of investigations on gaining control of limb movements are reviewed, and their contribution to understanding the development of manual asymmetries is discussed in relation to the discrimination and programming of appropriate neuromuscular resources. An examination of the relevant evidence on number and types of manual asymmetries recorded provides strong grounds for concluding that where asymmetries occur, they simply represent a further example of the well-documented activity-specific nature of motor skills and of the extremely lengthy periods of learning or experience needed for their acquisition and perfection. This specificity of motor skill and manual asymmetry also readily accounts for most of the discrepancy usually reported between assessments of hand preference and performance differences between hands, because these alternative measures of handedness have rarely employed the same range or variety of tasks.     

For the Right Reasons: The FORR Architecture for Learning in a Skill Domain

The theme of this article is that knowledge acquisition can be managed as a transition from general expertise to specific expertise. FORR is a general architecture for learning and problem solving that models expertise at a set of related problem classes. This architecture postulates initial brood domain knowledge, and gradually specializes it to simulate expertise in individual problem classes. FORR is based upon a realistic portrayal of the nature of human expertise and its application. Rather than restrict learning to a single method or a single kind of knowledge, the architecture pragmatically requires multiple, disagreeing heuristic agents to collaborate on decisions. A FORR-based program learns both from its apprenticeship to an external expert model and from practice in its domain. An implementation for game playing is described that raises interesting issues about the organization and modification of conflicting expertise, and the role that experience plays in such learning. FORR's principal strengths are its smooth integration of multiple expertise, its ability to learn many ways, its tolerance for human and machine error, its graceful degradation, its transparency, and its support for a developmental paradigm.     

Neurocognitive Contributions to Motor Skill Learning: The Role of Working Memory

ABSTRACT

Researchers have begun to delineate the precise nature and neural correlates of the cognitive processes that contribute to motor skill learning. The authors review recent work from their laboratory designed to further understand the neurocognitive mechanisms of skill acquisition. The authors have demonstrated an important role for spatial working memory in 2 different types of motor skill learning, sensorimotor adaptation and motor sequence learning. They have shown that individual differences in spatial working memory capacity predict the rate of motor learning for sensorimotor adaptation and motor sequence learning, and have also reported neural overlap between a spatial working memory task and the early, but not late, stages of adaptation, particularly in the right dorsolateral prefrontal cortex and bilateral inferior parietal lobules. The authors propose that spatial working memory is relied on for processing motor error information to update motor control for subsequent actions. Further, they suggest that working memory is relied on during learning new action sequences for chunking individual action elements together.     

Learning,Motor Skill,and Long-Range Correlations

Long-range correlations have been evidenced in a number of experiments, generally using overlearned and overpracticed tasks. The authors hypothesized that long-range correlation could represent the byproduct of learning. They analyzed the series of periods produced by a group of expert and a group of novices during prolonged trials on a ski simulator. Results showed a very low variability in expert's series, as compared to novices. Fractal analyses showed that fluctuations were significantly more structured and correlated in experts. These results suggest that learning could be conceived as the progressive installation of complexity in the system.

Engaging Environments Enhance Motor Skill Learning in a Computer Gaming Task

Engagement during practice can motivate a learner to practice more, hence having indirect effects on learning through increased practice. However, it is not known whether engagement can also have a direct effect on learning when the amount of practice is held constant. To address this question, 40 participants played a video game that contained an embedded repeated sequence component, under either highly engaging conditions (the game group) or mechanically identical but less engaging conditions (the sterile group). The game environment facilitated retention over a 1-week interval. Specifically, the game group improved in both speed and accuracy for random and repeated trials, suggesting a general motor-related improvement, rather than a specific influence of engagement on implicit sequence learning. These data provide initial evidence that increased engagement during practice has a direct effect on generalized learning, improving retention and transfer of a complex motor skill.     

The Clicker Technique: Cultivating Efficient Teaching and Successful Learning

The clicker technique is a newly developed system that uses frequent testing in the classroom to enhance students' understanding and provide feedback to students and teachers. Using a laboratory model of the clicker technique, Experiment 1 explored the effects of the clicker technique, via its potential for compressing learning time and its partially individualized instruction, on the acquisition, retention, and generalization of knowledge at immediate and delayed tests. Results supported the clicker technique as a viable method for instructors to promote generalizable learning and to conserve teaching time. Experiment 2 examined the clicker technique in terms of its components, studying and testing, to determine which components are crucial to its effectiveness. Results indicated that the combination of studying and testing promotes superior performance only during acquisition, relative to either studying or testing alone, and neither study, test, nor the combination of study and test led to a retention advantage.

Learning to Teach: The Acquisition and Maintenance of Teaching Skills

We reviewed 49 studies which used direct observation procedures to provide data on the effects of pre-service and inservice training in practical classroom teaching behaviors and skills. We found stronger effects for training packages which included classroom practice with performance feedback. The research provided conflicting evidence regarding the value of modeling, role-play, cueing systems, and contingency management components in practical skills training. The weakest training effects were those produced by microteaching, Minicourse, and protocol training packages. Twenty of the evaluations also provided follow-up data but the design of these studies did not permit any conclusions to be drawn regarding the training conditions which are necessary for the maintenance of newly acquired classroom teaching skills. We concluded that identification of the training conditions which are necessary for the maintenance of new teaching skills will require more thoughtful conceptualizations of maintenance and its measurement, and more carefully designed component analyses of those factors suggested by basic research as being necessary for maintenance.     

The Role of Task Experience and Prior Knowledge for Detecting Invalid Augmented Feedback while Learning a Motor Skill

Two hypotheses were investigated. These were generated from results reported by Buekers, Magill, and Sneyers (1994) and an uncertainty account of those and other effects on skill learning of erroneous knowledge of results (KR). The first hypothesis proposes that if experienced performers have developed the capability of detecting and correcting errors, then they should not be influenced by erroneous KR in the same way as novices. The second proposes that if information about the invalid feedback is given to subjects prior to the beginning of the practice trials, then the capability for assessing feedback can be accelerated such that subjects who receive this advance information should not be misled by the erroneous KR. The first hypothesis was investigated in Experiment 1 by having subjects practise an anticipation timing task for 450 trials. One group received correct KR on all trials, and another group received no KR. Half of the subjects in each group were unexpectedly switched to erroneous KR after 400 trials. Results indicated that the erroneous KR influenced both groups during acquisition and on a retention test one minute later. However, on a retention test given one week later, only the group that had practised with no KR before being switched to erroneous KR continued to show the negative influence of the invalid KR. The second hypothesis was examined in Experiment 2 by telling subjects prior to beginning practice trials that it was possible that the KR they received would be erroneous. Results showed that this intervention strategy was effective on the no-KR retention tests only for subjects who had no-KR trials alternated with trials on which they received the erroneous KR. The results of these experiments provide evidence that uncertainty about the validity of sensory feedback increases the likelihood that subjects will be misled by invalid augmented feedback. Moreover, this uncertainty can be overcome by increased experience or by providing advance knowledge about the nature of the invalid feedback.     

Variability of Practice and Contextual Interference in Motor Skill Learning

The purpose of this study was to investigate whether learning benefits in multiple-task learning situations are a result of contextual interference or of schema enhancement related to the amount of variability in the practice session. Two experiments were designed that replicated and extended the experiment reported by Wulf and Schmidt (1988). In a 2 (same vs. different relative time) x 2 (blocked vs. random practice schedule) design, 48 right-handed subjects were randomly assigned to one of four experimental conditions. A tapping task was employed that required a right-handed tap of three small brass plates arranged in a diamond pattern. Each segment had a specific time requirement. Target times and response times were provided on a computer screen directly in front of the subject. Each subject participated in two acquisition sessions (i.e., 198 practice trials) and was tested for learning on several different retention and transfer tests. In Experiment 2, a control group was added that received no acquisition phase. Results of both experiments showed a typical contextual interference effect, with depressed scores by the random groups during acquisition but significantly better scores than the blocked groups on several retention and transfer tests. Certain characteristics of the tests were found to influence the demonstration of the practice schedule effects. These results were consistent with predictions from Magill and Hall (1990) that the learning benefits of contextual interference are more likely to occur when skill variations are from different classes of movement and that the amount of variability in practice is more influential when the to-be-learned tasks are parameter modifications of the same generalized motor program.     

Self-Regulated Learning of a Motor Skill Through Emulation and Self-Control Levels in a Physical Education Setting

This study examined the effectiveness of the second and third level of Zimmerman's (2000) model of self-regulated learning development. Participants were 72 (28 boys and 44 girls) fifth- and sixth-grade students who practiced the novel task of dart-throwing. Results showed that sixth-grade Greek students who proceeded sequentially from the emulation to the self-control level improved their dart-throwing performance more than students who missed one or both of these levels, but fifth-grade students benefited equally either from the sequential practice at the emulation and the self-control level or from the experience at one of these self-regulatory levels. No differences were found in self-efficacy, although sixth-grade students who practiced at the emulation level reported higher satisfaction, and sixth-grade students who practiced at the self-control level reported higher intrinsic motivation compared to control group students. These results attest to the effectiveness of learning at the emulation and self-control levels and are discussed with reference to the social cognitive model of self-regulation development.     

Effect of Four Fatigue Levels on Performance and Learning of a Novel Dynamic Balance Skill

This study was to investigate the effect of fatigue on the performance and learning of the Bachman ladder task to determine if the relationship between activation and both the performance and learning data would support the inverted-U theory. Male Ss (N=48) were randomly assigned to four groups. A level of fatigue as determined by HR (Control, 120 BPM, 150 BPM, and 180 BPM) was assigned to each group. Each S was fatigued to his assigned level prior to the task and following each trial, was given 20 trials on Day 1 to learn the task while at his designated level, and then was given 20 additional trials on Day 2 under control conditions. On Day 1 150 and 180 BPM impaired performance of the motor task. The learning score data indicated that 150 and 180 BPM had a detrimental effect on learning of the task. Both the activation-performance and the activation-learning relationships partially supported the inverted-U theory.     

Toward a Developmental Diagnostic and Statistical Manual: The Vitality of a Contextual Framework

Counselors of all types need an understanding of and an ability to work with issues described by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994). The traditional approach to the DSM-IV tends to locate the problem in the client, whereas a developmental approach focuses on the client in social and historical context. Specific recommendations for organizing a comprehensive treatment plan are presented. The authors endorse an educational and developmental role for counselors.     

Effect of Analogy Instructions with an Internal Focus on Learning a Complex Motor Skill

This study examined the effects of an analogy in learning breaststroke swimming. Two groups of participants had 20 lessons on how to increase their stroke length. The participants in the experimental condition received an analogy with an internal focus of attention. Inter-limb coordination showed qualitative changes in this group: a greater increase in swimming efficiency (i.e., a coordination closer to anti-phase [?50° before learning and ?125° after] and a 10% decrease in the time spent in-phase). The findings showed that an internal focus of attention induced by analogy could be beneficial in improving the quality of inter-limb swimming coordination.
