Description:
Perceptual-cognitive skills and decision-making in sport have typically been explored using videobased protocols in settings where participants are not exposed to the type of competitive pressures that characterise a game situation. Consequently, this study aimed to investigate the influence of competitive pressure, or competitive anxiety, on decision-making accuracy. Seventy-seven (Male=44, Female=33) undergraduate students with mean age of 20.16 years (SD = 3.18) were randomly assigned to an experimental (n=56) or control group (n=21) and completed a video–based perceptual decision-making test of 25 temporally occluded offensive soccer plays. Participants in the experimental group completed the test with and without competitive pressure conditions. Pressure was manipulated by introducing a competition for a monetary prize. Participants in the control condition completed the test twice without competition. All participants completed a state anxiety measure prior to each test. The competition produced significantly higher cognitive anxiety than no competition; however, this was not reflected in any significant differences in decisionmaking accuracy. Although not statistically significant, more experienced performers tended to score more accurately with competitive pressure.

The aim of this study is to investigate the effects of in-game physical exertion on decision-making performance of Australian football umpires. Fifteen Australian football umpires (Mage = 36, s = 13.5 years; Mgames umpired = 235.2, s = 151.3) volunteered to participate in the study. During five competitive Australian football pre-season games, measures of in-game physical exertion (blood lactate levels, global positioning system [GPS]) and decision-making performance (video-based test) were obtained. There were no significant correlations between physical exertion in a particular quarter and decision-making performance in either the same quarter or any other quarter. Video-based decision-making performance was effected by time in game χ2(3) = 24.24, P = 0.001, with Quarter 4 performance significantly better than both Quarter 2 and Quarter 3. In-game physical exertion (blood lactate) significantly decreased over the course of the game χ2(3) = 11.58, P = 0.009. Results indicate no definable link between in-game physical exertion and decision-making performance. It is, however, presumed that decision-making performance may be affected by the time or context of the game. Future research is warranted to explore the relationship between physical exertion and decision-making performance to potentially inform Australian football umpire training programmes that replicate in-game physical and decision-making demands.
Description:
In this review we identified sport-based perceptual-cognitive training literature to systematically evaluate current video-based methodologies and their resultant effectiveness to improve perceptual-cognitive performance (i.e., decision-making). A comprehensive literature search of electronic databases from 1994-2013 was conducted to identify relevant studies. We identified 139 articles, of which 25 met all the inclusion criteria. Study design and test measures of the 25 articles were assessed against a classification scale to rate methodological quality. The methodological quality of the 25 studies varied, with quasi-experimental the most common design. Additionally, studies varied in the skill level of participants and the amount of video-based information presented during the training. We conclude that videobased training programs can be used to enhance perceptual-cognitive performance and outline several recommendations for future video-based perceptual-cognitive training programs particularly with respect to the validity and reliability of the instruments used to measure perceptual-cognitive performance.

OBJECTIVES: To develop a valid and reliable video-based decision-making test to examine and monitor the decision-making performance of Australian football umpires. DESIGN: Validation assessments with test re-test reliability. METHODS: A video-based decision-making test was developed from a pool of 156 video-based decision-making situations. Australian football umpires (n=56) and players (n=45) participated in two separate phases of analysis. In phase one, players completed a test re-test reliability assessment with a 100 video-clips. Results indicated 24 clips were a reliable measure of decision-making performance. In phase two, umpires completed a test re-test protocol with 80 clips, 24 of which were the reliable clips identified by the player cohort in phase one. These 24 clips provided a measure of construct validity. Face and content validity were assessed by skill acquisition specialists, expert umpire coaches, and umpires. RESULTS: From each of phase one and two of the reliability assessment, 24 clips were found to have a kappa value greater than 0.30, providing a total of 48 reliable video-clips. Construct validity was supported, with the umpire group performing significantly better than the player group on the 24 clips presented to both groups on each testing occasion. Face and content validity were also demonstrated. CONCLUSIONS: This investigation demonstrated the ability prospectively to determine reliability and validity of the video-based decision-making test designed specifically for Australian football umpires. Establishing the validity and reliability of the video clips ensures future investigations can accurately and consistently measure the decision-making performance of Australian football umpires.
Description:
Decision-making is a central component of the in-game performance of Australian football umpires; however, current umpire training focuses largely on physiological development with decision-making skills development conducted via explicit lecture-style meetings with limited practice devoted to making actual decisions. Therefore, this study investigated the efficacy of a video-based training programme, aimed to provide a greater amount of contextualised visual experiences without explicit instruction, to improve decision-making skills of umpires. Australian football umpires (n = 52) were recruited from metropolitan and regional Division 1 competitions. Participants were randomly assigned to an intervention or control group and classified according to previous umpire game experience (i.e., experienced; less experienced). The intervention group completed a 12-week video-based decision-making training programme, with decision-making performance assessed at pre-training, and 1-week retention and 3-week retention periods. The control group did not complete any video-based training. Results indicated a significant Group (intervention; Control) x Test interaction (F(1, 100) = 3.98; P = 0.02, partial 2 = 0.074), with follow-up pairwise comparisons indicating significant within-group differences over time for the intervention group. In addition, decision-making performance of the less experienced umpires in the intervention group significantly improved (F(2, 40) = 5.03, P = 0.01, partial 2 = 0.201). Thus, video-based training programmes may be a viable adjunct to current training programmes to hasten decision-making development, especially for less experienced umpires.

This study investigated the effects of imagery training on reactive agility and whether reacting to unpredictable stimuli could be improved using imagery. Forty-seven female athletes (Mage = 21.51, SD = 2.32) were randomly assigned to either a three-week physical training, imagery training, or control condition. Physical training condition involved physically rehearsing the reactive agility task, whereas the imagery training condition involved imagining the presenting stimulus and performing the reactive agility task. The control condition did no reactive agility training. A 3 (training conditions) x 7 (reactive agility performance components) mixed-model MANOVA was conducted to examine changes in reactive agility performance from the training interventions. Physical training improved decision time components and overall reactive agility performance. Imagery training improved Stimulus-Decision Time and Stimulus-Foot performance, but not overall reactive agility performance. No performance improvements occurred for the control condition. Findings support imagery use for the decision time variables associated with lightstimulus reactive agility performance. The lack of overall reactive performance improvement may indicate that imagery training is not effective for all components of perceptual-motor performance. Performance change inconsistencies appear to indicate that participants may not have generated unpredictable stimuli during imagery. Future investigation as to whether imagery improvements translate to sport-specific reactive tasks is needed.

Description:
Video-based training is a commonly used method to develop decision-making in athletes and officials. This method typically uses match broadcast footage, yet technological advancements have made 360° Virtual Reality (360°VR) a possible effective tool to investigate. This study aimed to investigate the effectiveness of both 360°VR and match broadcast footage on improving decision-making. Amateur Australian football umpires (N= 32) participated in a randomised control trial. Participants completed a 5-week training intervention in either a 360°VR, match broadcast or control group. Decision-making was assessed at pre-training, 1-week post-training and 4-week retention points using reliable and valid 360°VR and match broadcast decision-making tests. Participants completed a short questionnaire detailing their perceptions of psychological fidelity, enjoyment, relevance, concentration and effort for each video mode. The 360°VR performed significantly better (p < 0.05) than the control group in the 360°VR retention test. No groups statistically improved over the intervention. Remaining pairwise comparisons for this test and the match broadcast test were not significantly different. 360°VR was rated significantly higher (p < 0.05) than match broadcast footage for psychological fidelity, enjoyment and relevance. 360°VR appears to be a beneficial training tool compared to a control, with stronger engagement from the participants than previously used match broadcast footage.

While recent research has indicated that personalised motor imagery (MI) interventions are beneficial to skill performance, little research has investigated the influence of personalised MI on performance of complex weightlifting movements. In addition, this research has rarely compared the efficacy of personalised scripts with instructor-generated scripts and has focused mainly on performance outcomes as opposed to examining the performance processes. A total of 16 individuals novice in the power clean were randomly allocated to one of two conditions: personalised MI, or instructor-generated MI. Participants engaged in a 6-week training intervention, completing three power clean sessions per week. Scripts were listened to five times each week. Results indicated no significant between-condition differences for total forward displacement at 1RM and 90% 1RM (both p = 0.27), but there was a significant difference at 80% of 1RM for total forward displacement between conditions (p = 0.04, g = −0.94). Differences between conditions for rearward displacement were not significant at any intensities (p = 0.54). No significant (p = 0.16-0.97) between-condition differences in kinetic variables were detected at any intensity over the 6-week training period. Findings indicate that the differences in script content do not influence the development of complex weightlifting movements. A large degree of variation was evident when observing the SD's of technical variables for each group which may have contributed to the present results. Future research should seek analysis techniques that allows for further investigation of movement variability and how this impacts the efficacy of personalised MI.
Description:
This study examined the use of imagery according to Paivio's (1985) general analytic framework. The aims were to examine functional differences in imagery use according to the five subscales of the SIQ, to investigate differences in imagery use by competitive level, and to explore the influence on the use of imagery of skills involving a perceptual target (reactive tasks) and without a perceptual target (nonreactive tasks). Participants included 484 individuals (280 male, 204 female), with a mean age of 20.39 (SD = 4.10) from the United Kingdom, Finland, and Australia. The group comprised 84 national, 210 state, 120 district, and 70 recreational level athletes representing 54 sports. Participants completed a demographic information sheet and the Sport Imagery Questionnaire (SIQ). Participants were classified according to competitive level and task type. Results indicated that overall participants used more motivational general-mastery imagery. A one-way multivariate analysis of variance revealed that there were significant differences among the four competitive levels on imagery use with the district level participants reporting significantly higher use of motivational general-arousal (MG-A) imagery than state and national level participants and national level participants reporting higher use of cognitive specific (CS) imagery than recreational level participants. There was also a significant difference between tasks with a perceptual target and tasks with no target for motivational-specific imagery, with higher scores for tasks with a perceptual target. The results suggest the continued evaluation of imagery use in relation to competitive level and support that task type may influence the functional use of imagery in sport.
Description:
Stereotypes and self-perceptions are important in understanding how people develop their self-knowledge and social identity, become members of groups, and view groups and their members. While we have some understanding of the stereotypical view of the physical education teacher, we currently have little knowledge of how physical education pre-service teachers (students studying a physical education degree) are stereotyped, and also if there is any relationship between these stereotypes and how physical education pre-service teachers perceive themselves. The purpose of this study was to examine the stereotypes and self-perceptions of physical education pre-service teachers. The aims were to describe how physical education pre-service teachers stereotype and perceive themselves, examine if there are differences in the stereotypes and self-perceptions between males and females, and to explore if there were relationships between what the physical education pre-service teachers believed stereotyped them and how they perceived themselves. Participants were 250 students (n=120 males, n=130 female) studying a 4-year Bachelor of Education (Physical Education) degree at a university who completed a questionnaire which contained 10 items about how they viewed physical education pre-service teachers (stereotypes), and 26 items on how they viewed male physical education pre-service teachers and female pre-service teachers (stereotypes) and 26 items on how they view themselves (selfperceptions). Factor analysis revealed 2 stereotype factors, which were labelled as Sociable (e.g., socialise, partying, drinking, loud and outgoing) and Health and Lifestyle (e.g., fit, playing sport and not smoking). The stereotype of the male physical education pre-service teacher, comprised two factors: physical, assertive and aggressive behaviour (e.g., aggressive, dominant, self-confident, and competitive) and physical and self-presentation factors (muscular, athletic, physically fit, physically coordinated, and attractive). The stereotype of female physical education pre-service teachers comprised three factors: physical appearance and ability (e.g., physically fit, athletic, able-bodied, attractive, thin, and physically coordinated), aggressive and assertive behavioural style (e.g., intimidating, unapproachable, and aggressive), and masculine behavioural style (e.g., aggressive, masculine, feminine, muscular and dominant). The self-perception of male physical education pre-service teachers comprised three factors: perceived appearance and ability (e.g., athletic, physical fit, thin, attractive, muscular and pleased with their body), aggressive and confident behaviour (e.g., intimidating, dominant, show off and aggressive) and independence and intellect (e.g., independent, ambitious, self confident and intelligent). The self-perception of female physical education pre-service teachers comprised three factors: strong willed behaviour (e.g., ambitious, and dominant), presentation and appearance (e.g., pleased with their body, attractive, thin and self confident), and aggressive and dominant behaviour (e.g., aggressive, intimidating, masculine and show off). There were significant relationships between the male physical and self-presentation stereotype factor stereotype and perceived appearance and ability self-perception factor and between the male physical, assertive and aggressive behaviour stereotype factor and the male aggressive and confident behaviours self-perception factor. For females, the aggressive and dominant behaviour stereotype was related to both the aggressive and assertive behavioural style self-perception factor and the masculine behavioural style self-perception factor. It is suggested that future studies investigate the stereotypes and self-perceptions of students in schools during the recruitment phase of socialisation, and the possible influence of the physical education teacher education programme, faculty leaders, and significant others on the physical education pre-service teachers' self-perceptions, stereotypes and soci lisation into physical education.
Description:
Physical practice is the cornerstone of acquiring and developing movement skills in physical education and sport. However, research has suggested that psychological tools, such as mental imagery (MI), could effectively supplement a learner's physical practice schedule. MI is the mental simulation of a movement or situation in the absence of an overt physical output. Previous reviews have established the efficacy of MI for improving motor skills in sport. Further investigation, however, will help strengthen previous findings by focusing exclusively on studies that apply MI programs for the development of sport-specific motor skills. The purpose of this paper is to examine the overall effectiveness of MI programs for developing sport-specific motor skills and investigate program principles that may moderate the efficacy of MI programs, such as practice type, skill level, skill complexity, performance measures, duration, practice setting, and session frequency. By examining key program variables for MI, this review seeks to provide practical recommendations for physical educators and sports coaches on how they might effectively design and deliver a MI program to develop sport-specific motor skills. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. To provide practical recommendations for physical educators and sports coaches for effective MI programs, the following moderator variables were examined using subgroup analysis: (1) skill complexity, (2) skill level, (3) program duration, (4) session frequency, (5) MI practice type, and (6) practice context. The PEDro scale was used to assess study quality. The presence of publication bias was evaluated using the Trim and Fill method to calculate an adjusted and unbiased overall effect. The systematic review included 36 studies (n = 1449). A random-effects meta-analysis of standardised mean differences yielded an initial 135 individual effect sizes. A composite approach accounted for statistical dependence between effects and yielded 58 individual effects for further analysis. Analysis indicated that MI has a significant effect on performance (g = 0.476). Further analysis revealed significant effects on performance outcomes for MI combined with physical practice and MI alone (g = 0.579 and 0.298, respectively). Subgroup analyses revealed these beneficial effects be moderated by skill complexity, elements of skill performance, and MI delivery type. These results presented in our meta-analysis highlight the overall benefit of MI practice for developing sport-specific motor skills. However, there is a paucity of research on the effects of MI on complex skills and in physical education and sport coaching contexts. Although most studies presented in this review were conducted in controlled research settings, there are clear parallels between the skills practiced in these studies and those implemented in physical education and sport coaching. The efficacy of MI alone presents a potentially beneficial tool when physical practice is not possible or when physical training needs reduction (e.g. in-season sports competition). Therefore, it is encouraged that physical educators and sports coaches collaborate with sport psychology practitioners to investigate the efficacy of the several MI program variables presented in this review.
Description:
It is unclear whether task representation generated in imagery simulates performance demands in reacting to stimuli. This study investigated whether perceptual and motor control processes used to react to unpredictable stimuli and initiate an ipsilateral movement were replicated during imagery. Fifty-nine undergraduate students (Mage = 27.01 years, SD = 8.30) completed 30 simple, two-choice congruent and two-choice incongruent ipsilateral finger–foot movement trials in response to a physically presented or imagined stimulus. The results appear to indicate that participants were reacting to imagined and actual stimuli, as the ipsilateral finger–foot programming rule was maintained and reaction time initially slowed as task difficulty increased. These findings support theoretical similarities between imagery and physical performance of reaction tasks, with imagers generating and reacting to unpredictable stimuli. Slower imagery performance than physical performance on the two-choice incongruent task may indicate that task complexity is limited during imagery. Variation in results between the imagery and physical conditions potentially supports that imagers were able to react to the imagined stimulus. However, exploratory processes used to react to stimuli were not replicated during imagery. The present findings have potentially significant implications for the functional and applied use of imagery for skill acquisition.
