English soccer teams' aggressive behavior when playing away from home

Speculation about key factors affecting home advantage still exists. The present study investigated aggressive behavior amongst English Football Premiership (soccer) players and its relation to home advantage. The frequency of aggressive behaviour, identified by the award of a penalty or disciplinary card (yellow for caution or red for dismissal) was analysed over 2000-2003. Chi-square analyses assessed whether a greater frequency of aggressive behavior was performed by teams away from home. In decided matches, teams playing away received significantly more cautions (yellow cards) than home teams. A further analysis of tied matches indicated that away teams received significantly more cautions (yellow cards) than home teams. No significant differences between home and away teams were found for dismissals and penalties awarded. Reasons for these findings are considered.     

Assessing cue usage in performance contexts: A comparison between eye-movement and concurrent verbal report methods

The relationship between eye fixations and concurrent verbal reports as measures of selective attention was examined in two different performance contexts. Experienced and less experienced soccer players were presented with filmed action sequences. In Experiment 1, subjects reacted to 11-versus-11 soccer simulations; in Experiment 2, 3-versus-3 situations were presented. Each study involved two experimental conditions: (1) visual fixations were recorded using an eye-movement system and (2) subjects continuously verbalized the location of their visual attention. In 11-versus-11 situations, there were no differences in performance across the two conditions, indicating that verbalization had no effect on performance. Also, there were no differences between the two methods in identifying important information sources. In 3-versus-3 situations, concurrent verbalization resulted in reactivity. Moreover, there were differences between the two methods in identifying important display areas. Findings showed that the relationship between visual fixation and selective attention is dependent on the nature of the stimulus presented. When peripheral vision is employed to extract task-specific information, verbal reports provide a more veritable measure of selective attention; eye fixations may yield a more accurate measure when the task requires information to be extracted foveally. Findings are discussed with regard to the differences between “looking” and “seeing” as a methodological issue.     

Manipulated stress and dispositional reinvestment in a wall-volley task: an investigation into controlled processing

This field-based study examined the action of reinvesting in controlled processing on 14 university soccer players to assess skill breakdown under pressure. Based on scores on the Reinvestment Scale of Masters, Polman, and Hammond, two experimental groups of participants were inferred to be dispositionally High or Low in Reinvestment. They performed a wall-volley soccer task, which involved kicking a ball repeatedly against a wall target zone for 90 sec. as defined by McMorris, Gibbs, Palmer, Payne, and Torpey in a High and Low Stress environment. Prior to each condition performers were required to complete the Anxiety Rating Scale. A series of two-way (reinvestment x stress) analyses of variance with repeated measures on stress were conducted on the Anxiety and soccer scores. Players scoring High on the Reinvestment Scale reported significantly greater Intensity for Somatic Anxiety and lower Self-confidence than players who scored Low in the High Stress condition. Anxiety Direction scores indicated players scoring High on the Reinvestment Scale reported their increase in Somatic Anxiety and reduction in Self-confidence in the High Stress condition to be significantly more debilitating of performance than players who scored Low on the Reinvestment Scale. Soccer scores indicated players scoring High on the Reinvestment Scale were more prone to reinvesting in controlled processing and essentially experiencing greater decreases in performance under pressure than those Low in Reinvestment. Therefore, these findings support the predictive power of the Reinvestment Scale.     

Perceptual-cognitive performance of youth soccer players in a 360°-environment – Differences between age groups and performance levels

IntroductionAn important requirement for soccer players is the accurate and rapid processing of dynamic and complex visual scenes. Therefore, in high-level youth soccer the players’ perceptual-cognitive skills are highly relevant from a scientific and practical point of view. The aim of the present study was to investigate differences in perceptual-cognitive performance between youth soccer players of different age groups and soccer performance levels in a dynamic 360°-environment.MethodsIn a sample of 292 elite and sub-elite youth soccer players from the age groups U12–U23, perceptual-cognitive skills were assessed using a 360°-multiple object tracking task. An 8 × 2 (age group x performance level) analysis of variance (ANOVA) was conducted to examine the effects of age group and soccer performance level on performance in the task.ResultsThe analyses revealed a significant main effect of age group. Post hoc analyses showed that youth players belonging to the older age groups (U16, U17, U19, and U23) performed significantly better in the 360°-multiple object tracking task than players of the youngest age group (U12). Yet no significant age-related differences could be found from age group U16 on. Furthermore, there was a significant effect of soccer performance level on the 360°-multiple object tracking performance in favor of the elite players. Significant differences between elite and sub-elite players within the same age group were only present in the highest age groups U19 and U23.ConclusionsThe results suggest that in a dynamic 360°-environment highly talented youth soccer players show better perceptual-cognitive performance with increasing age. Furthermore, elite youth players exhibit distinctive perceptual-cognitive abilities particularly at the highest age groups. These findings provide interesting implications for science and practice regarding the perceptual-cognitive skills of talented soccer players and their role in talent development.     

Experience level influences the effect of attentional focus on sprint performance

Two experiments evaluated the influence of attentional focus on 10-meter sprint time and start kinetics in a group of collegiate soccer players and highly experienced sprinters. In Experiment 1, the collegiate soccer players were asked to perform 10-meter sprints under an external focus condition, an internal focus condition and a control condition. For the 10-meter sprint time, the results showed that both the external focus and control conditions resulted in significantly faster sprint times than the internal focus condition. There were no significant differences observed between the external focus and control conditions. There were also no significant differences observed across any of the conditions for a select set of kinetic variables. In Experiment 2, the highly experienced sprinters performed the same 10-meter sprint task using the same instructional conditions as in Experiment 1. For the 10-meter sprint time and kinetic variables, there were no significant differences observed across any of the conditions. These results provide new evidence that experience level mediates the influence of attentional focus on sprint performance.     

Field dependence and physical ability.

Field-dependence scores of professional dancers, highly skilled performers in tennis, soccer, cricket and track and field athletics, medium-ability level players in the same four sports and a group of non-game players were measured using a rod and frame test. Results showed that highly skilled tennis players were significantly more field-dependent than top-class track and field athletes and medium-ability level tennis players.     

Static one-legged balance in soccer players during use of a lifted leg

The goal was to describe static one-legged balance during use of a lifted leg and to compare balance between the dominant and nondominant legs of soccer players. Participants were 17 male soccer players and 17 untrained male students (control). Balance ability was evaluated with four sway measures: sway velocity, anterior-posterior sway, medial-lateral sway, and high-frequency sway. Soccer players had smaller magnitude mean anterior-posterior and medial-lateral sway than untrained students. Although mean sway velocity and anterior-posterior sway were higher with the dominant leg than in the nondominant leg of the control group, there was no significant difference on any sway factor between the two legs of the soccer group. In conclusion, the soccer players were observed to have superior static one-legged balance during use of a lifted leg, and there is no difference in balance for the two legs in the soccer group.     

A Pre-Match Video Self-Modeling Intervention in Elite Youth Football

In this study, a self-modelling video intervention was delivered to four elite youth soccer players over 13 weeks of the competitive soccer season. A multiple-baseline, repeated measures single-subject design was used to explore the impact of the intervention on subcomponents of soccer performance and psychological variables, including self-efficacy and positive/negative affect. Statistical analysis indicated that there were significant changes between pre- and post-intervention scores for two players (1 & 3) on three subcomponents of performance (turns, headers and tackles). The findings of this study highlight the potential benefits of designing individualised pre-match video interventions with elite youth athletes.

Lay Summary:

Video self-modelling (VSM) is a behavioural intervention in which an athlete views a video of themselves engaged in adaptive behaviour, in order to learn to reproduce it effectively under pressure. In this study, the impact of a self-modelling video intervention is examined within a youth football soccer environment.     

Stress,Coping, and Emotions on the World Stage: The Experience of Participating in a Major Soccer Tournament Penalty Shootout

This study was designed to capture the first-hand experiences of stressors, coping, and emotions that elite professional soccer players have during a major soccer penalty shootout. Eight players who each took part in an important European Championships penalty shootout were interviewed. The results showed that the experience of stressors, coping, and emotions changed extensively throughout the event. Moreover, the participants experienced a series of different stressors, some of which were specific to the penalty shootout, and they employed a variety of coping strategies. Anxiety was the most common emotion. Practitioners can use these results to help design valid simulation protocols.     

Self-Regulation of Practice Behavior Among Elite Youth Soccer Players: An Exploratory Observation Study

This study aimed to measure behavioral correlates of self-regulation in elite youth soccer players. Behaviors regarded as indicative of self-regulated learning were identified by interviewing six expert youth soccer coaches. These behaviors were observed during practice of eight elite youth soccer players aged 15–17 years, and linked with self-reported self-regulated learning scores to describe behavioral correlates of self-regulation. Results indicated that self-regulated learning is reflected in taking responsibility for learning and that players’ practice environment plays a significant role. This study highlights the importance of measuring overt behavior to gain a complete impression of youth soccer players’ self-regulated learning skills.     

Self-Control in Professional Soccer Players

This study aimed to investigate the concept of self-control in association with engagement in daily activities of professional soccer players and its relationship with soccer performance. Findings indicated that self-control scores of male professional soccer players (N = 639), representing the first squad of every club playing in the (Norwegian) Premier and Second League, were associated with their lifestyle and practice time. A small, positive relationship between self-control and soccer performance was found. In terms of expert performance, a possible explanation of our findings is that self-control helps individuals stay on track on their pathways to excellence.     

Perceptual-cognitive expertise, practice history profiles and recall performance in soccer

We examined whether high- or low-performing soccer players, classified based on established measures of perceptual-cognitive expertise, differed in regard to their practice history profiles and ability to recall elements of match performance. In Study 1, we measured perceptual-cognitive expertise in elite (n= 48) and non-elite (n= 12) youth soccer players using empirical tests of perceptual-cognitive skill. We then used a quartile split to stratify elite players into either high-performing (n= 12) or low-performing (n= 12) groups based on their test scores. A group of non-elite soccer players (n= 12) acted as controls. In Study 2, we used an established questionnaire to examine retrospectively the participation history profiles of the three groups. The high-performing group had accumulated more hours in soccer-specific play activity over the last 6 years of engagement in the sport compared to their low-performing counterparts and the non-elite controls. No differences were reported for hours accumulated in soccer-specific practice or competition between the high- and low-performing groups. In Study 3, a novel test was developed to examine episodic memory recall in soccer. Although this test successfully differentiated elite from non-elite players, no differences were evident between high- and low-performing groups, implying that episodic memory recall may not be a crucial component of perceptual-cognitive expertise in soccer.     

Dynamic visual acuity and coincidence-anticipation timing by experienced and inexperienced women players of fast pitch softball

This study examined the relationship between dynamic visual acuity and coincidence-anticipation timing in 16 inexperienced and 16 experienced women's fast pitch softball players. Pearson-product correlations indicated a low relationship between dynamic visual acuity and coincidence-anticipation timing. The correlations for dynamic visual acuity and coincidence anticipation between experienced and inexperienced dynamic visual acuity were not significant. A significant difference was found between the mean dynamic visual acuity of the two groups, i.e., experienced players had better dynamic visual acuity than inexperienced players. Analysis of variance of constant errors, variable errors, and absolute errors of coincidence anticipation indicated no significant differences between groups or across the three accuracy scores. The interaction between experience and accuracy was not significant.     

Examining the Relationship Between Action Video Game Experience and Performance in a Distracted Driving Task

We conducted two experiments to assess the hypothesis that experienced action video game players will exhibit superior performance in a distracted driving task. In the first experiment, experienced gamers and controls drove in a driving simulator, with and without distraction. Experienced AVG players exhibited fewer lane deviations during driving as compared to non-gamers; however, video game experience was not associated with fewer lane deviations while distracted. These results showed evidence for the video game experience effect however, no evidence of improved cognitive ability was found. In the second experiment, we informed participants of the hypothesis to replicate the methods of studies that do not mask the purpose of the research. We found video game experience again was associated with fewer driving errors, but was still not associated with better driving performance while distracted; however, gamers recalled more details of the distracting conversation and reported lower workload while driving than non-gamers. We use these results to argue for caution in interpreting research with experienced gamers and increased replication with attention paid to recruitment methodology within this research domain. Finally, our results indicate that understanding the nature of AVG experience on task performance requires careful attention to motivational factors.     

Interval endurance capacity of talented youth soccer players

The purpose of this study, in which 113 talented youth soccer players (M = 16.0 yr., SD = 1.5), selected by their age and level of performance participated, was to investigate interval endurance capacity needed to play at the highest level of competition in the age-category 12 through 18. Multivariate analyses of covariance with factors of level of performance and age category showed that players ages 16 through 18 years outscored the players ages 12 through 15 years on the interval endurance capacity (p < .05). In both age categories, elite players outscored less skilled players (p < .05). In the age category 12-15 years, the elite players participated more in soccer training than less skilled players (p < .05), whereas less skilled players participated more in additional training than the elite players (p < .05). No differences were found for total training (p > .05). In conclusion, development of the interval endurance capacity seems crucial for a talented youth soccer player to be successful.     

“Decisions,decisions, decisions”: transfer and specificity of decision-making skill between sports

The concept of transfer of learning holds that previous practice or experience in one task or domain will enable successful performance in another related task or domain. In contrast, specificity of learning holds that previous practice or experience in one task or domain does not transfer to other related tasks or domains. The aim of the current study is to examine whether decision-making skill transfers between sports that share similar elements, or whether it is specific to a sport. Participants (n = 205) completed a video-based temporal occlusion decision-making test in which they were required to decide on which action to execute across a series of 4 versus 4 soccer game situations. A sport engagement questionnaire was used to identify 106 soccer players, 43 other invasion sport players and 58 other sport players. Positive transfer of decision-making skill occurred between soccer and other invasion sports, which are related and have similar elements, but not from volleyball, supporting the concept of transfer of learning.     

Effects of the axis of rotation and primordially solicited limb of high level athletes in a mental rotation task

A recent set of studies has investigated the selective effects of particular physical activities that require full-body rotations, such as gymnastics and wrestling (Moreau, Clerc, Mansy-Dannay, & Guerrien, 2012; Steggemann, Engbert, & Weigelt, 2011), and demonstrated that practicing these activities imparts a clear advantage in in-plane body rotation performance. Other athletes, such as handball and soccer players, whose activities do require body rotations may have more experience with in-depth rotations. The present study examined the effect of two components that are differently solicited in sport practices on the mental rotation ability: the rotation axis (in-plane, in-depth) and the predominantly used limb (arms, legs). Handball players, soccer players, and gymnasts were asked to rotate handball and soccer strike images mentally, which were presented in different in-plane and in-depth orientations. The results revealed that handball and soccer players performed the in-depth rotations faster than in-plane rotations; however, the two rotation axes did not differ in gymnasts. In addition, soccer players performed the mental rotations of handball strike images slower. Our findings suggest that the development of mental rotation tasks that involve the major components of a physical activity allows and is necessary for specifying the links between this activity and the mental rotation performance.     

Affect and job satisfaction: a study of their relationship at work and at home

The authors investigated 2 broad issues: (a) across- and within-individual relationships between mood and job satisfaction and (b) spillover in moods experienced at work and at home. Using an experience-sampling methodology, they collected multisource data from a sample of 74 working individuals. Multilevel results revealed that job satisfaction affected positive mood after work and that the spillover of job satisfaction onto positive and negative mood was stronger for employees high in trait-positive and trait-negative affectivity, respectively. Results also revealed that the effect of mood at work on job satisfaction weakened as the time interval between the measurements increased. Finally, positive (negative) moods at work affected positive (negative) moods experienced later at home.     

Perceiving patterns of play in dynamic sport tasks: investigating the essential information underlying skilled performance

The perceptual-cognitive information used to support pattern-recognition skill in soccer was examined. In experiment 1, skilled players were quicker and more accurate than less-skilled players at recognising familiar and unfamiliar soccer action sequences presented on film. In experiment 2, these action sequences were converted into point-light displays, with superficial display features removed and the positions of players and the relational information between them made more salient. Skilled players were more accurate than less-skilled players in recognising sequences presented in point-light form, implying that each pattern of play can be defined by the unique relations between players. In experiment 3, various offensive and defensive players were occluded for the duration of each trial in an attempt to identify the most important sources of information underpinning successful performance. A decrease in response accuracy was observed under occluded compared with non-occluded conditions and the expertise effect was no longer observed. The relational information between certain key players, team-mates and their defensive counterparts may provide the essential information for effective pattern-recognition skill in soccer. Structural feature analysis, temporal phase relations, and knowledge-based information are effectively integrated to facilitate pattern recognition in dynamic sport tasks.
