Accelerating Visual Anticipation in Sport Through Temporal Occlusion Training: A Meta-Analysis

BACKGROUND

The video-based temporal occlusion paradigm has been consistently used in visual anticipation sport research.

OBJECTIVE

This meta-analysis investigated the magnitude to which video-based temporal occlusion training could improve anticipation skill with transfer to representative laboratory and field tasks.

METHODS

As there are considerably fewer anticipation training than performance studies, the meta-analysis included 12 intervention studies with 25 effect sizes where video simulation and/or field-based tests were used. The Downs and Black checklist adapted for sports science research was used to assess methodological quality of the included studies. Decision time and accuracy of anticipation were the outcome measures because both are relevant to sports skills. The changes in these measures between experimental and control groups from baseline to the transfer test context were used to calculate the magnitude of the training effect.

RESULTS

Findings revealed a significant training effect, including a large meta-analytic effect size, and no difference in training benefit across video and field-based transfer tests. Publication bias analyses were inconclusive, likely due to the small number of available studies.

CONCLUSIONS

These findings are evidence that the temporal occlusion paradigm is an effective method to improve visual anticipation skill across representative perceptual and perceptual-motor transfer tests. The theoretical implication based upon the two-stage model of visual anticipation is that temporal occlusion training can improve use of early information for body positioning by the performer, which could in turn lead to improved execution of the skill goal.

Virtual reality perceptual training can improve the temporal discrimination ability of swinging during softball batting

Perception and action uncoupling in fastball sports anticipatory training is often criticized. Nevertheless, perception-only training offers distinct advantages, such as flexibility concerning time, place, and injury limitations. Therefore, the effectiveness of this training approach warrants evaluation. This study developed a virtual reality (VR) training system based on the idea that the two visual pathways in the brain are associated with visual information attributes, rather than perception or action. A key feature of this study's perception-only training was its presentation of not only the opponent's kinematics but also the ball's flight information (the attributes that guide hitting) to train the visual system necessary for real situations. Seventeen female softball batters were assigned to two groups: a training group (N = 9) and a control group (N = 8). Only the training group underwent the VR anticipatory skill training to discriminate the different ball speeds. Both groups completed a perception test and an action test on the VR during the pre- and post-training periods. The perception test assessed response accuracy (RA) in discriminating ball speed, and the action test assessed the temporal difference in swing onset (delta onset). Comparison of these two outcome variables between groups revealed that perception-only training improved both perceptual and action responses. This study demonstrated the effectiveness of perception-only training and emphasized the need for its thoughtful utilization and design.

Attributes of Expert Anticipation Should Inform the Design of Virtual Reality Simulators to Accelerate Learning and Transfer of Skill

Expert sport performers cope with a multitude of visual information to achieve precise skill goals under time stress and pressure. For example, a major league baseball or cricket batter must read opponent variations in actions and ball flight paths to strike the ball in less than a second. Crowded playing schedules and training load restrictions to minimise injury have limited opportunity for field-based practice in sports. As a result, many sports organisations are exploring the use of virtual reality (VR) simulators. Whilst VR synthetic experiences can allow greater control of visual stimuli, immersion to create presence in an environment, and interaction with stimuli, compared to traditional video simulation, the underpinning mechanisms of how experts use visual information for anticipation have not been properly incorporated into its content design. In themes, this opinion article briefly explains the mechanisms underpinning expert visual anticipation, as well as its learning and transfer, with a view that this knowledge can better inform VR simulator content design. In each theme, examples are discussed for improved content design of VR simulators taking into consideration its advantages and limitations relative to video simulation techniques. Whilst sport is used as the exemplar, the points discussed have implications for skill learning in other domains, such as military and law enforcement. It is hoped that our paper will stimulate improved content design of VR simulators for future research and skill enhancement across several domains.

Behavioral Measures in a Cognitive-Motor Batting Task Explain Real Game Performance of Top Athletes

Excellent athletic performance in baseball and softball batting is achieved through the momentary cognitive-motor processes. However, in previous studies, cognitive and motor processes are investigated separately. In this study, we focused on the difference in the time of swing onset (a delta onset) during a batting task where 17 elite female softball batters hit balls randomly thrown at two different speeds by pitchers. The delta onset included both cognitive and motor processes because the batters needed to anticipate the ball speed and discriminate their swing motion according to the time-to-contact. Then, we investigated the relationship between the delta onset and the batting outcomes of the batting task, and the relationship between the experimental outcomes and actual batting performance (batting average) over a season. We used path analysis to clarify the structure of the cognitive-motor processes and consequent performance. We found that the batters who had a larger delta onset attained superior batting outcomes (i.e., higher exit velocity and lower miss ratio) in the batting task, and these experimental outcomes explained 67% of the batting average in real games. On the other hand, the cognitive scores (judgement accuracy and rapidity) obtained from a button pressing task, where batters responded to a ball by pressing a button instead of actually swinging, explained only 34% of the batting average. Therefore, our model quantitatively describes the key cognitive-motor structure for athletes and can partially predict a batter's performance in real games. These findings suggest that it is important to employ both cognitive and motor processes in performing tasks, such as this batting task, to properly evaluate a batter's actual ability.

Sources of information pick-up for anticipation by skilled cricket batsmen

This study investigated whether skilled West Indian cricket batsmen could use contextual and kinematic information to anticipate the type of ball being bowled. Thirty-one participants were recruited that formed first class (n = 10), elite club (n = 10), and elite youth representative (n = 11) groups. Each group completed a video temporal occlusion batting test under two conditions. Condition one presented bowler kinematic information; that is, occlusion occurred at back-foot, front-foot, and ball release, with a no occlusion control. Condition two presented game contextual information in the form of field placings that was congruent with the ball types prior to temporal occlusion trials. Results revealed no significant skill group differences in the timing of information pick-up under kinematic or contextual conditions. Prediction accuracy for all skill groups was at guessing level at each temporal occlusion that presented kinematic information, but was above chance at no occlusion. Prediction accuracy for all skill groups increased to above guessing level at advance cue temporal occlusions when contextual information was provided. Findings indicate that this group of skilled batsmen did not use kinematic information for anticipation in this temporal occlusion task, but relied heavily upon contextual information. An implication of this study is that skilled batsmen should be targeted for visual-perceptual training to pick-up contextual and kinematic information to guard against deception from the latter that can negatively impact batting performance.

Use of Pitcher Game Footage to Measure Visual Anticipation and Its Relationship to Baseball Batting Statistics

Professional baseball batters’ (N = 105) visual anticipation of pitch type and location were measured using a video-based temporal occlusion test and correlated with their baseball batting statistics. Participants watched in-game footage of skilled baseball pitchers that was temporally occluded at the point of ball release, and at 80 ms and 200 ms after ball release. Participants made written predictions of pitch type and location. Results indicated there was a significant positive correlation between anticipation of combined pitch type and location 80 ms after ball release with slugging percentage (r = .21). There was a significant negative correlation between anticipation of pitch type alone 200 ms after ball release and strikeouts (r = −.28), indicating higher prediction is associated with fewer incorrect swing choices. Furthermore, there was a significant positive correlation between anticipation of pitch type alone 200 ms after ball release and on-base percentage (r = .23) as well as walk-to-strikeout ratio (r = .25). These small relationships are consistent to the batting statistics we predicted and can be due to the range of competitive levels in the leagues the participants had played. The findings further theoretical and applied knowledge of the role visual anticipation contributes to baseball batting game performance. The findings also suggest that game footage can be used to assess and potentially to train visual anticipation skill, which is highly valuable for athletes and high performance support staff in sporting organizations.

Adaptability of expert visual anticipation in baseball batting

By manipulating stimulus variation in terms of opponent pitcher actions, this study investigated the capability of expert (n = 30) and near-expert (n = 95) professional baseball batters to adapt anticipation skill when using the video simulation temporal occlusion paradigm. Participants watched in-game footage of two pitchers, one after the other, that was temporally occluded at ball release and various points during ball flight. They were required to make a written prediction of pitch types and locations. Per cent accuracy was calculated for pitch type, for pitch location, and for type and location combined. Results indicated that experts and near-experts could adapt their anticipation to predict above guessing level across both pitchers, but adaptation to the left-handed pitcher was poorer than the right-handed pitcher. Small-to-moderate effect sizes were found in terms of superior adaptation by experts over near-experts at the ball release and early ball flight occlusion conditions. The findings of this study extend theoretical and applied knowledge of expertise in striking sports. Practical application of the instruments and findings are discussed in terms of applied researchers, practitioners and high-performance staff in professional sporting organisations.
