The development of a method for identifying penalty kick strategies in association football

Abstract Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteristics that observers should use to distinguish the two strategies. We asked participants to rate 12 characteristics of pre-recorded clips of kicks of penalty takers that used either a keeper-independent or keeper-dependent strategy. A logistic regression model identified three variables (attention to the goalkeeper, run-up fluency and kicking technique) that in combination predicted kick strategy in 92% of the penalties. We used the model in Experiment 2 to analyse prevalence and efficacy of both the strategies for penalty kicks in penalty shoot-outs during FIFA World Cups (1986–2010) and UEFA Football Championships (1984–2012). The keeper-independent strategy was used much more frequently (i.e., 78–86%) than the keeper-dependent strategy, but successes did not differ. Penalty takers should use both the strategies to be less predictable. Goalkeepers can use the developed model to improve their chances to succeed by adjusting their behaviour to penalty takers’ preferred penalty kick strategy.

Implicit Goalkeeper Influences on Goal Side Selection in Representative Penalty Kicking Tasks

In well-controlled lab situations, marginal displacements of the goalkeeper on the goal line affect goal side selection of penalty takers implicitly, that is, without the penalty takers being consciously aware of the displacement. Whether this effect is retained in more representative real-life situations with competing goalkeepers and penalty takers has not been verified. In the current study, penalty takers were instructed to position the goalkeepers at the centre of the goal. They then performed penalty kicks adopting either a keeper independent or a keeper dependent strategy, while goalkeepers actually attempted to save the ball by strategically diving early or late. Analyses of trials in which penalty takers failed to place the goalkeeper in the centre of the goal (although they incorrectly believed they placed the goalkeeper at the centre of the goal) showed that implicit influences of the goalkeeper’s position on goal side selection were overridden by the (conscious) perception of the direction of the goalkeeper’s dive, but only if the penalty takers deliberately monitored the goalkeeper’s action and the goalkeeper committed early enough for penalty takers to respond. In all other combinations of penalty kick and goalkeeper strategies more than 60% of the kicks were directed to the side of the goal with more space. Most importantly, however, the current study shows that influences of implicit perception on the penalty takers’ decision making are rather pervasive considering that many supraliminal sources of information were available. That is, the current study demonstrates that implicit perception retains its influence on decision-making even if other (stronger) stimuli are also present.

A review of behavioural measures and research methodology in sport and exercise psychology

ABSTRACT This study examined the development of methodologies and measures used in sport and exercise psychology (SEP) publications between 1979 and 2013. A systematic coding process was conducted on a total of 1377 manuscripts sampled from four long-standing SEP publications, namely Journal of Applied Sports Psychology, Journal of Sport and Exercise Psychology, Psychology of Sport and Exercise, and The Sport Psychologist. Analyses compared the type of behavioural or non-behavioural measures used, and the research design employed. Findings suggested that overall SEP has included more behavioural measures in comparison to other psychology domains, and there has been substantial sampling of sport and exercise behaviours using direct rather than indirect behavioural measures. Nevertheless, proportions of dependent behavioural measures in SEP were significantly less than non-behavioural measures. Questionnaires have remained a dominant non-behavioural measure over time, and higher proportions of SEP studies were conducted within a semi-natural social setting. Findings are discussed in line with SEP practice, and the potential implications for future works.

Asymmetries in spatial perception are more prevalent under explicit than implicit attention

Observers typically show systematic errors in spatial perception when asked to bisect a line. We examined whether misbisection relates to the extent by which the midpoint is scrutinized explicitly. Participants were required to position a soccer goalkeeper at the exact midpoint of the goal line, drawing explicit attention to the midpoint of the line. Subsequently, they carried out a penalty kick to score a goal, without eliciting explicit attention for the centre of the goal for choosing the side to which to kick the ball. We found that participants positioned the goalkeeper to the right of the centre, confirming the previously reported rightward bias for line bisections in extra-personal space. Although participants (erroneously) believed that the goalkeeper stood in the centre, they kicked the ball to the bigger side of the goal more often. These findings indicate that asymmetries in spatial perception are more evident with explicit than implicit attention.

Courting on the beach: how team position implicitly influences decision-making in beach volleyball serves

ABSTRACT Masters, van der Kamp, and Jackson [2007. Imperceptibly off-centre goalkeepers influence penalty-kick direction in soccer. Psychological Science, 18, 222–223] demonstrated that a goalkeeper in soccer penalty kicking standing marginally to one side of the goal’s centre unconsciously influences a penalty takers’ goal side selection. In two experiments, we examined whether the positions of the receiving players in beach volleyball affect a player’s decision to what area of court to play. Both experiments differed in the degree of attention participants directed to the largest court area. Results showed that participants made decisions favouring the larger court area although they were unaware of the receivers’ asymmetrical positioning. This effect was more pronounced in Experiment 1, suggesting that the degree to which attention is directed to the critical information (i.e. largest court area) can be considered an important moderator. These observations indicate that implicit effects of positioning reflect a more general phenomenon in and outside of sports that can be exploited for improving chances of success.

Rumination and Performance in Dynamic, Team Sport

People high in rumination are good at tasks that require persistence whereas people low in rumination is good at tasks that require flexibility. Here we examine real world implications of these differences in dynamic, team sport. In two studies, we found that professional male football (soccer) players from Germany and female field hockey players on the US national team were lower in rumination than were non-athletes. Further, low levels of rumination were associated with a longer career at a higher level in football players. Results indicate that athletes in dynamic, team sport might benefit from the flexibility associated with being low in rumination.

Evaluating erroneous offside calls in soccer

The ability to simultaneously attend to multiple objects declines with increases in the visual angle separating distant objects. We explored whether these laboratory-measured limits on visual attentional spread generalize to a real life context: offside calls by soccer assistant referees. We coded all offside calls from a full year of first division German soccer matches. By determining the x-y coordinates of the relevant players and assistant referee on the soccer field we were able to calculate how far assistant referees had to spread their visual attention to perform well. Counterintuitively, assistant referees made fewer errors when they were farther away from the action due to an advantageous (smaller) visual angle on the game action. The pattern held even when we accounted for individual differences in a laboratory-based attentional spread measure of ten of the assistant referees. Our finding that errors are linked to smaller visual angles may explain the complaints of fans in some situations: Those seated directly behind the assistant referee, further from the players, might actually have it easier to make the right call because the relevant players would form a smaller visual angle.

Attention towards the goalkeeper and distraction during penalty shootouts in association football: a retrospective analysis of penalty shootouts from 1984 to 2012

ABSTRACT In the present study, we tested the consequences of attention towards goalkeepers in association football penalty shootouts that have exclusively been derived from laboratory experiments. We conducted a retrospective analysis of all penalty shootouts during FIFA World Cups (1986–2010) and UEFA European Football Championships (1984–2012). We linked key variables of previous laboratory research to observable behaviour in the field that was coded by two independent coders. The following hypotheses were tested: first, attention towards goalkeepers results in more saves/better goalkeeper performance; second, goalkeepers can deliberately distract penalty takers by drawing attention towards themselves which results in less accurate penalty kicks/better goalkeeper performance. Results were in line with previous laboratory analyses as they showed that attention towards goalkeepers resulted in more saves/better goalkeeping performance. Further, if goalkeepers distracted penalty takers this also resulted in better goalkeeping performance. The applied implications of these findings are discussed for both goalkeepers and penalty takers in association football.
