Autonomy Support via Instructionally Irrelevant Choice Not Beneficial for Motor Performance or Learning

Purpose: The Optimizing Performance Through Motivation and Attention for Learning (OPTIMAL) theory predicts that providing learners with choices during skill acquisition will enhance their acquisition performance, motor learning, and expectancies. Based on this theory, it is recommended that instructors ask learners to choose which tasks to practice in applied settings. This experiment tested these predictions and recommendation by crossing autonomy support with practice schedule in a 2 × 2 factorial design. Method: Participants (N = 128) practiced a novel non-dominant hand dart-throwing task either with choice over the color of the dart flights (autonomy) or yoked to a counterpart's choices (yoked). Further, participants either practiced throwing darts to three different targets in equal amounts (variable) or throwing to the same target for all practice trials (constant). All participants completed a pretest, acquisition phase, 24-hr delayed retention and transfer tests, as well as baseline and post-acquisition autonomy, and self-efficacy measures. Data were analyzed according to a pre-registered analysis plan that included pretest and gender as covariates. Results: The autonomy groups reported significantly greater perceived autonomy at the end of acquisition. There were no significant effects of autonomy on self-efficacy, or motor performance uniquely during acquisition, or uniquely on the delayed transfer test. The autonomy groups, however, performed with significantly greater error across acquisition and transfer. Practice schedule interacted with the time of testing such that the constant groups performed significantly more accurately during acquisition but non-significantly less accurately during transfer than the variable groups. Conclusions: These results are inconsistent with OPTIMAL theory.

The recommendation for learners to be provided with control over their feedback schedule is questioned in a self-controlled learning paradigm

Evidence that self-controlled feedback schedules are more effective for motor learning than yoked or predetermined schedules has been used to forward the recommendation that practitioners should provide choice to learners over when they would like to receive feedback. This recommendation can be questioned because the typical comparison groups in such experimentation do not well represent the applied setting. Consequently, comparison groups that better map onto the applied setting are needed. To this end, three groups learned a golf putting task: (1) self-controlled, (2) traditional-yoked, and (3) a group who were led to believe their KR schedule was being controlled by a golf coach. Participants (N = 60) completed a pre-test, acquisition phase, and delayed post-tests (retention/transfer). No group differences during the post-tests for mean radial error, F(2, 54) = 2.71, p = .075, or bivariate variable error, F(2, 56) = 0.11, p = .896, were found. Thus, the typical self-controlled learning advantage was not observed. Given the failure to replicate self-controlled benefits, combined with the fact there is little research that has directly compared self-controlled feedback schedules to coach-controlled schedules, we argue more evidence is needed before advocating that learners be provided choice over their feedback schedule.

Varied speeds of video demonstration do not influence the learning of a dance skill

The effects of slow-motion and real time video speed demonstration, under mixed-modeling conditions (skilled model plus self-observation), were examined to identify whether there was an optimal demonstration speed, or combination thereof, for learning the dance pirouette en dehors skill. Fifty-one participants were randomly assigned to one of three groups with different video demonstration speeds: (1) slow-motion, (2) real-time, or (3) a combination of slow-motion and real-time. Following a pre-test, participants completed eight blocks of nine training trials (comprised of five physical and four observational practice trials). Physical performance and cognitive representation assessments revealed that participants' scores significantly improved for both assessments throughout acquisition (p's < 0.05), as well as from pre- to post-test (p's < 0.001), indicating learning of the skill. There were no significant differences, however, between the three experimental groups. These findings suggest that both real-time and slow-motion video demonstration, or their combined presentation, do not yield differences in motor learning outcomes related to the pirouette en dehors.

Revisiting the Applied Model for the Use of Observation: A Review of Articles Spanning 2011-2018

Purpose: To provide a review of current articles that have used observation interventions to enhance motor skill acquisition or performance of applied tasks, and to situate the research within the Applied Model for the Use of Observation (AMUO) with the goal of forming a basis for evidence-based guidelines for practitioners. Method: Key words (e.g., observation/modeling) were searched in varied data bases (e.g., Google Scholar/PubMed), along with a citation search of the relevant AMUO article, to generate a pool of articles for possible review. Selection criteria included publication between 2011 and 2018, and that the research focus was on the effects of an observation intervention on the acquisition or performance of an applied motor task. Results: Forty-eight articles were reviewed, with 21 of these targeting the basic question of whether observation is effective, and the remaining pertaining to the What, When, Who, and How features of the AMUO. The effectiveness of observation interventions was not only affirmed, but also extended to a wider scope of populations and settings. Greater insight into the necessary information with respect to the demonstration (what) and whether it should be before, after, or during physical practice (when) was obtained. As well, advantages of combining model types (who) and providing control to the learner (how) were reported. Conclusions: While more clarity was brought to certain features of the AMUO that could be used to provide evidence-based guidelines, more research is needed to fully inform practitioners for the effective use of observation interventions.

Feedforward Self-Modeling and Self-Regulation: It's Not Just for Learning

Purpose: This research investigated whether Zimmerman's model of self-regulated learning could be transferred into a competitive setting. We also investigated whether a feedforward self-modeling video could influence one's use of self-regulation and as such be an effective self-regulatory intervention. Methods: Nine competitive gymnasts took part in two interviews; one interview was conducted after a competition in which the video was viewed (experimental interview: EI) and the other after a competition where no video was seen (control interview: CI). Results: The gymnasts' responses to the interviews suggested that many processes and beliefs used in the learning context described by Zimmerman were also engaged in within a competitive context. Furthermore, comparison of gymnasts' responses between the EI and CI suggested that the feedforward self-modeling video influenced gymnasts' use of self-regulation during a competition. Conclusion: This research suggests that Zimmerman's model of self-regulation has potential to be transmitted into the competitive context and that an individual's self-regulation can be influenced by viewing a feedforward self-modeling video.

Examining the impact of error estimation on the effects of self-controlled feedback

Two experiments were conducted that examined the motivational and informational perspectives concerning learning advantages from self-controlled practice. Three groups were tasked with learning a novel skill; self-controlled (SC), yoked traditional (YT), and yoked with error estimation required during the acquisition phase (YE). Results from the delayed learning measures showed the YE group performed better than the SC and YT groups, for Expt. 1. A similar pattern emerged for Expt. 2, albeit, this was not significant. While there were no motivation differences across the groups in either experiment, a strong correlation in Expt. 2 was shown between error estimation capabilities, which were best for the YE group, and learning. These combined results suggest that informational processes contribute more to the self-controlled feedback learning advantage, relative to motivational contributions.

International Bias in Gymnastic Judging: Conscious or Unconscious Influences?

A clear pattern of international bias in gymnastic judging is that judges award gymnasts from their own country higher scores than other judges who have evaluated the same routine. Two experiments tested whether international bias in gymnastic judging could be partially explained by unconscious influences in the form of exposure or perceptual fluency effects. It was reasoned that repeated exposure to a gymnast's routine would lead to perceptual fluency effects that would be misattributed to increased appreciation of the routine. This misattribution could result in judges awarding higher scores. No support was provided for the hypothesis of unconscious influences. The results are discussed in terms of the possible factors that contributed to a null effect and the practical implications for gymnastic judging.

Self-controlled feedback is effective if it is based on the learner's performance: a replication and extension of Chiviacowsky and Wulf (2005)

The learning advantages of self-controlled feedback schedules compared to yoked schedules have been attributed to motivational influences and/or information processing activities with many researchers adopting the motivational perspective in recent years. Chiviacowsky and Wulf (2005) found that feedback decisions made before (Self-Before) or after a trial (Self-After) resulted in similar retention performance, but superior transfer performance resulted when the decision to receive feedback occurred after a trial. They suggested that the superior skill transfer of the Self-After group likely emerged from information processing activities such as error estimation. However, the lack of yoked groups and a measure of error estimation in their experimental design prevents conclusions being made regarding the underlying mechanisms of why self-controlled feedback schedules optimize learning. Here, we revisited Chiviacowsky and Wulf’s (2005) design to investigate the learning benefits of self-controlled feedback schedules. We replicated their Self-Before and Self-After groups, but added a Self-Both group that was able to request feedback before a trial, but could then change or stay with their original choice after the trial. Importantly, yoked groups were included for the three self-controlled groups to address the previously stated methodological limitation and error estimations were included to examine whether self-controlling feedback facilitates a more accurate error detection and correction mechanism. The Self-After and Self-Before groups demonstrated similar accuracy in physical performance and error estimation scores in retention and transfer, and both groups were significantly more accurate than the Self-Before group and their respective Yoked groups (p’s < 0.05). Further, the Self-Before group was not significantly different from their yoked counterparts (p’s > 0.05). We suggest these findings further indicate that informational factors associated with the processing of feedback for the development of one’s error detection and correction mechanism, rather than motivational processes are more critical for why self-controlled feedback schedules optimize motor learning.

Describing strategies used by elite, intermediate, and novice ice hockey referees

Much is known about sport officials' decisions (e.g., anticipation, visual search, and prior experience). Comprehension of the entire decision process, however, requires an ecologically valid examination. To address this, we implemented a 2-part study using an expertise paradigm with ice hockey referees.

PURPOSE

Study 1 explored the strategies referees indicated they used to make decisions. For Study 2, we sought to confirm the emergent codes of Study 1 and further examine referee expertise and evaluations of decision making.

METHOD

In Study 1, 2 elite, 2 intermediate, and 2 novice referees wore helmet cameras for 1 game and participated in stimulated recall interviews, which were coded using theoretical and focused codes. Study 2 involved focus groups that each watched and commented on 2 helmet camera videotapes from Study 1; 1 videotape consisted of an elite referee's game and the other included an intermediate referee's game. The focus-group data were analyzed using the same coding structure from Study 1.

RESULTS

Combined, 3 distinct theoretical codes were identified: (a) primary referee strategies, (b) secondary referee strategies, and (c) cognitive and situational influences on refereeing. Study 1 showed that elite referees demonstrated more sophisticated knowledge of the 3 theoretical codes. In Study 2, elite referees demonstrated enhanced declarative knowledge compared with intermediate and novice participants.

CONCLUSIONS

Elite referees have more elaborate knowledge bases than do nonelite referees. In the discussion, we explain our results and link them with the action plan profiles framework.

Coach selections and the relative age effect in male youth ice hockey

Relative age effects (RAEs; when relatively older children possess participation and performance advantages over relatively younger children) are frequent in male team sports. One possible explanation is that coaches select players based on physical attributes, which are more likely witnessed in relatively older athletes.

PURPOSE

To determine if coach selections are responsible for RAEs by comparing RAEs in male players who played competitive versus noncompetitive ice hockey.

METHODS

Using chi-square, we analyzed the birth dates of 147,991 male ice hockey players who were 5 to 17 years old. Players' birth dates were divided into four quartiles, beginning with January to March, which coincides with Hockey Canada's selection year.

RESULTS

There were strong RAEs (p < .001) when players were selected to competitive teams by coaches through a tryout system. On noncompetitive teams that did not have coach selections, there were strong RAEs (p < .001) from 5 to 8 years old, but not 9 to 17 years old.

CONCLUSIONS

Although coaches might perpetuate RAEs, other influential social agents might include parents, which ought to be investigated in future research.

Learner-Controlled Self-Observation is Advantageous for Motor Skill Acquisition

There were two main objectives of this research. First, we wanted to examine whether video feedback of the self (self-observation) was more effective for motor skill learning when the choice to view the video was provided to the learner (learner-controlled, LC) as opposed to an experimenter-controlled (EC) delivery. Secondly, we explored whether there were differences in the self-regulatory processes of self-efficacy and intrinsic motivation, as well as perceived choice between the LC and EC conditions. Two groups (LC and EC) of children (M age of 11.2 years; SD = 1.89) attempted to learn a progression of trampoline skills during a 2-day acquisition phase in which video self-observation was available. The second acquisition day was followed by a no self-observation retention test 1 day later. It was hypothesized that, during retention, the LC group would be more self-efficacious about their ability to progress through the trampoline skills, show greater intrinsic motivation and perceived choice, and go further in skill progression than the EC group. Analysis of the acquisition data showed the LC group had greater increases in self-efficacy as compared to the EC group. Results of the retention test showed that the participants in the LC group obtained higher scores on the intrinsic motivation and perceived choice measures and had higher skill progression scores as compared to the EC group. Regression analysis showed that group assignment and self-efficacy were significant predictors of the physical performance benefits noted in retention. These findings are discussed within Zimmerman's (2004) self-regulation of learning model.

Feedforward self-modeling enhances skill acquisition in children learning trampoline skills

The purpose of this research was to examine whether children would benefit from a feedforward self-modeling (FSM) video and to explore possible explanatory mechanisms for the potential benefits, using a self-regulation framework. To this end, children were involved in learning two five-skill trampoline routines. For one of the routines, a FSM video was provided during acquisition, whereas only verbal instructions were provided for the alternate routine. The FSM involved editing video footage such that it showed the learner performing the trampoline routine at a higher skill level than their current capability. Analyses of the data showed that while physical performance benefits were observed for the routine that was learned with the FSM video, no differences were obtained in relation to the self-regulatory measures. Thus, the FSM video enhanced motor skill acquisition, but this could not be explained by changes to the varied self-regulatory processes examined.

The impact of self-as-a-model interventions on children's self-regulation of learning and swimming performance

We compared two self-as-a-model interventions: self-modelling (viewing oneself perform an adaptive behaviour) and self-observation (viewing oneself perform at current skill level). Operating within Zimmerman's (1989, 2000) theory of self-regulated learning, we examined the effect of the modelling interventions on three self-regulatory processes (self-efficacy, intrinsic motivation, and self-satisfaction), as well as physical performance. Thirty-three children were randomly assigned to one of three experimental groups. The two self-as-a model groups received the modelling intervention just before physical practice, whereas the control group received physical practice only. Analyses of the retention scores revealed significant differences for all dependent measures. Post hoc testing showed consistently that the self-modelling group performed better than the self-observation and control groups, and that the two latter groups performing similarly. These results provide support for the implementation of self-modelling interventions with children when teaching motor skills.

High Levels of Contextual Interference Enhance Handwriting Skill Acquisition

The authors conducted 3 experiments to examine whether introducing high levels of contextual interference is useful in handwriting skill acquisition. For all experiments, elementary school students (Ns = 44, 50, and 78, respectively) were randomly assigned to 1 of 2 practice schedules-blocked or random practice-in the acquisition phase. In the blocked condition, each of 3 letters (h, a, and y) or (in Experiment 1) symbols was handwritten 24 times consecutively. In the random condition, each letter (or symbol) was practiced 24 times, but in an intermixed, unsystematic sequence. Overall, the results showed that the random practice schedule leads to enhanced retention and transfer performance of handwriting skill acquisition.

Decision-making by experienced rugby referees: use of perceptual information and episodic memory

The expertise paradigm was used in two studies to examine decision-making by rugby referees. Videoclips were used to assess infraction detection and knowledge base, or sources of information used. In Study 1, referees of high and low experience were compared, and in Study 2 referees and players were compared. Analysis by signal detection used a framework to classify types of information. Study 1 yielded no differences in detection of infractions as a function of experience, however, referees of high experience used significantly more sources of information than the group with low experience across all categories of information. In Study 2, there were no significant differences between referees and players, with the exception that referees displayed greater use of episodic memory information in decision-making.

Expertise in women's gymnastic judging: an observational approach

Observation was used to study expertise in gymnastic judging. 10 expert and 10 novice gymnastic judges were videotaped while judging at actual competitions. Analyses showed that novice judges, as compared to expert judges, spent less time looking at the gymnast perform, spent more time looking at the scoring paper, and were less able to engage in the dual-task demands required in gymnastic judging.
