- Description: 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. © The Author(s) 2024.

- Description: This study investigated whether performance of an interceptive skill requires an intact visual-perception-action cycle. Eleven skilled male Australian rules football athletes (Mage = 17.54, SD = 0.15) were recruited from an elite developmental pathway squad for a within-subject study. Participants were required to kick a ball directly at a goal from a 20-meter distance while wearing a pair of stroboscopic glasses. The glasses were used to create four vision conditions. Condition one kept intact the visual-perception-action cycle with uninterrupted vision of the motor skill. Three other conditions included stroboscopic vision that presented temporal samples of vision, which interrupted the perception-action cycle through progressive increases to intermittent vision occlusion of the motor skill. Goal kick error of ball position relative to a central target line within the goal and number of successful goals kicked were measured. Written report of internal and external focus of attention was also measured after each vision condition. Generalized estimating equation analysis did not reveal a significant decrement in kick target error, nor accuracy of goals scored, across normal to stroboscopic vision conditions. Performance was maintained despite a shift in attention focus from external to internal across normal to stroboscopic vision conditions. These findings have theoretical and practical implications for the visual regulation of skilled interceptive actions. Copyright © 2024 Müller, Beseler, Morris-Binelli and Mesagno.

- Description: 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. © 2022, The Author(s).

- Description: Perceptual-cognitive-motor skills, such as visual anticipation, are pivotal for superior performance in sport. However, there are only a limited number of skill acquisition specialists working with coaches to develop these skills in athletes. The purpose of this paper is to present a brief reflection on the use of psychological strategies to create an autonomy-supportive environment to embed a skill acquisition research project in high-performance sport. The research project was conducted with the Australian national field hockey high-performance unit and investigated individual differences in expert goalkeepers’ visual anticipation. The paper first discusses the role of a skill acquisition specialist, how they collaborate with coaches and athletes, and barriers to collaboration. The paper then outlines how psychological strategies can be used to create an autonomy-supportive environment to build a relationship and establish a research collaboration with a team. Further, the paper discusses the importance of continually involving coaches and athletes in the research process to facilitate their engagement and self-determined motivation to complete the project. By applying psychological strategies to create an autonomy-supportive environment, sports scientists may have greater success in overcoming the many barriers to conduct research in an elite sport setting, with the outcomes highly valuable for athlete development. © 2021 Association for Applied Sport Psychology.

- Description: SIGNIFICANCE Visual anticipation is vital for performance in several domains such as driving, military, and high-speed interceptive sports, as it enables performers to handle severe time constraints. There has been little investigation into individual differences of anticipation skill transfer within a domain, which can guide training of anticipation to improve performance. PURPOSE The purpose of this study was to investigate individual differences in the transfer of anticipation within a domain, specifically anticipation of the field hockey penalty corner drag-flick across different opponents. METHODS Eight female Australian international and national field hockey goalkeepers participated. Goalkeepers completed female and male opponent penalty corner drag-flick temporal occlusion tests that presented contextual defensive runner positioning relative to the penalty spot, drag-flicker kinematics, and ball flight. RESULTS Drag-flick movement time and ball velocity were significantly different across female and male opponents confirming that a transfer continuum existed. Five goalkeepers could transfer integration of runner contextual and drag-flicker kinematic information to anticipate loose runs above chance from female to male opponent tests. None of the goalkeepers could transfer integration of contextual and kinematic information for the tight runs across female to male opponents. CONCLUSIONS An individual differences approach with truly expert performers provided unique insights into the mechanism of anticipation transfer within a domain. The findings of this study contribute to theoretical and applied knowledge, which can guide the training of anticipation skill to prepare individuals for superior performance. © Lippincott Williams & Wilkins.

- Description: In interceptive sports such as field hockey goalkeeping, the psycho-perceptual-motor skill anticipation is vital for performance due to the extreme time constraints associated with saving a goal. The purpose of this study was to understand the beliefs and attitudes of international field hockey goalkeepers and coaches regarding anticipation of the drag-flick in penalty corners. Seven international goalkeepers and five international coaches were interviewed. Using a constructionist and relativist approach to reflexive thematic data analysis, we identified three overarching themes to anticipate the drag-flick, namely, pre-match video analysis, perception and action, and psychological factors. In the first theme, participants reported that pre-match video analysis allowed goalkeepers and coaches to identify the attacking capabilities of opposing teams. This analysis was used to inform defensive structure and save the drag-flick. In the second theme, participants reported that perception and action, which consisted of the pick-up of visual cues and movement execution, was important to anticipate the drag-flick. Goalkeepers reported that they rely heavily on ball flight, which was central in coaches’ approaches in training drills such as to use a projection machine that presents only ball flight information. The third theme, psychological factors, encompassed, psychological resilience, arousal regulation, leadership and communication, and sports intelligence, which were thought to be vital to facilitate anticipation of the drag-flick. The findings of this study have important implications for how to assess and train visual anticipation in time-constrained interceptive sports skills. © 2020 Elsevier Ltd

In this position paper, we argue that inclusion of psycho-perceptual-motor skills, from the fields of sport psychology and sport expertise, is crucial, but underutilized in the assessment and training of athletes. First, a brief introduction is provided as to why psycho-perceptual-motor skill is vital for training athletes. Second, examples are discussed relating to key concepts. These include the following: assessment of expertise discriminators such as visual anticipation under pressure contexts, incorporation of sports analytics and performance analysis to aid reflection upon previous experiences of good anticipation and coping with pressure, use of qualitative and quantitative measures to understand processes underlying performance and learning, as well as design of representative tasks for assessment and training anticipation under pressure contexts. Third, some recommendations are made to practitioners of sports teams to assist them in taking advantage of psycho-perceptual-motor skill to better prepare athletes for competition. Collectively, we hope this paper stimulates collaboration between practitioners of sports teams and scientists to create a greater focus upon integrated sport psychology and sport expertise in the training of athletes.

- Description: 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. © 2018 Human Kinetics, Inc.

- Description: Superior performance in striking sports requires anticipation skill because of constraints imposed on the performer, which can make it extremely difficult to achieve the motor skill goal. This article reviews the empirical literature on expert visual anticipation in striking sports since 2012 to determine if it has contributed to advancement of a theoretical model. First, methodologies used to study visual anticipation are briefly described. Second, an existing model is outlined to present what is known about the theoretical underpinning of expert visual anticipation. Third, empirical evidence of key factors that contribute to expert visual anticipation are discussed. Moreover, whether anticipation skill can be improved and transferred to different contexts is discussed. The review identifies that there are multiple key factors that contribute to expert visual anticipation performance, which need to be more thoroughly accommodated as part of the theoretical model. There is still less empirical evidence of learning and transfer of visual anticipation skill even though both of these are vital to improve motor skill performance, as well as apply any improvement to anticipation skill in different in situ settings. Collectively, this review provides an update of the research on expert visual anticipation and identifies future research directions that can continue to further knowledge in striking sports. © 2017 Canadian Psychological Association.
