“…Notwithstanding their depth of experience, a strong and systematic influence of the amount and direction of spin was found for the professional soccer players' judgments of whether the ball would end up in the goalmouth or not (Craig et al, 2006). The group of non-soccer-players participating in Experiment 1 revealed very much the same pattern of results (see Figure 1).…”

“…Craig et al (2006) suggested that this was due to an inherent limitation of the human visual system, which is incapable of dealing with the ever-varying accelerative influence of the Magnus force created by spin. In line with this suggestion, the present series of experiments revealed that the non-soccer-players' anticipatory judgments were also significantly influenced by the laterally deviating ball terns ( s; Lee, 1998) of change of the angle .…”

“…This interaction effect was due to a difference obof the sphere or air density, have an effect on how a sphere flies through the air, this study focused on the effects of sidespin that provoked a lateral deviation in a soccer ball's flight path. Craig et al (2006) reported that such an aerodynamic modulation of the flight trajectory influenced the ability of professional soccer players (both goalkeepers and field players) to anticipate where a ball was going. Experiment 1 extended this study to include a group of novices.…”

International audienceAlthough many studies have looked at the perceptual-cognitive strategies used to make anticipatory judgments in sport, few have examined the informational invariants that our visual system may be attuned to. Using immersive interactive virtual reality to simulate the aerodynamics of the trajectory of a ball with and without sidespin, the present study examined the ability of expert and novice soccer players to make judgments about the ball's future arrival position. An analysis of their judgment responses showed how participants were strongly influenced by the ball's trajectory. The changes in trajectory caused by sidespin led to erroneous predictions about the ball's future arrival position. An analysis of potential informational variables that could explain these results points to the use of a first-order compound variable combining optical expansion and optical displacement

“…Why do players try to put spin on the trajectory make it more difficult for the goal-keeper to anticipate where the ball is going and subsequently control their actions to actually get there? In other words does spin give the attacker a competitive advantage?This talk will present experimental work that significantly how to act (Craig et al, 2006). By immersing players in a virtual soccer stadium and allowing them to interact with realistic curved free kicks we show to what extent the impact upon the decision making process (Dessing & Craig, 2010).…”

According to humans and animals perceive and interact with surfaces (e.g. grass), places (e.g. pitch), objects (e.g. ball) and events (e.g. a set-play) (Gibson, 1966). All these so called properties of the surrounding environment provide opportunities for action. This relationship between the environment and player and the ensuing action possibilities are known as affordances. Affordances are essentially the starting point for psychologists trying to understand how humans perceive, learn, and decide to act upon events they perceive to be taking place in their surrounding environment (Turvey, 1992). This area of psychology assumes a player-environment to perceive and perceive to move processes and action capabilities are therefore intricately linked and play a crucial role in the decision making process.Virtual reality provides the perfect adjunct to study perception/action in sport. It is in essence a sophisticated interactive and immersive humancomputer interface where a sensory environment (visual, haptic and/or acoustic) is simulated by a computer and is controlled by the interactive behaviour of the user. It is a versatile methodological tool that gives the experimenter complete control over complex environmental conditions and allows for an inpsychology this technology is starting to be exploited as a means of treating phobias (VRET), monitoring behaviour of autistic children in virtual classrooms, rehabilitating stroke patients and most recently in testing perception/action capabilities in elite sports players (Bideau et al, 2006;Craig et al, 2006). The versatility of the VR platform means the technology can be easily applied to a multitude of sports.For instance, the systematic variation of the visual information available to the players (e.g. the ball trajectory and/or the run-up of the attacking/defending player) will influence the way actions are guided. The objective of the research presented here is to determine how visual information picked up from the visual environment influences the actions and decisions being made by the players in the game of soccer. For instance, deciding when and how to move is very important when keeping goal in soccer. Goal-keepers must attend to pertinent visual information (player and ball) that will allow them to judge where the ball is going, to get their body in the right place at the right time. However, more and more teams are exploiting the free-kick scenario as an opportunity for scoring goals (Grant et al, 1999). This appears to be related to the freedefensive wall. Why do players try to put spin on the trajectory make it more difficult for the goal-keeper to anticipate where the ball is going and subsequently control their actions to actually get there? In other words does spin give the attacker a competitive advantage?This talk will present experimental work that significantly how to act (Craig et al, 2006).

In real situations, analyzing the contribution of different parameters on sports performance is a difficult task. In a duel for example, an athlete needs to anticipate his opponent's actions to win. To evaluate the relationship between perception and action in such a duel, the parameters used to anticipate the opponent's action must then be determined. Only a fully standardized and controllable environment such as virtual reality can allow this analysis. Nevertheless, movement is inherent in sports and only a system providing a complete freedom of movements of the immersed subject (including displacements) would allow the study of the link between visual information uptake and action, that is related to performance. Two case studies are described to illustrate such use of virtual reality to better understand sports performance. Finally, we discuss how the introduction of new displacement devices can extend the range of applications in sports. IntroductionSport is gaining an increasing place in nowadays societies, not only as an entertainment but also as a socio-economical matter. There is now overwhelming evidence that regular physical activity has important and wide-ranging benefits on health [14]. Moreover, sport offers great pedagogical values for young people. It conveys moral values and requires appropriate behaviors in groups. As a consequence, studying sports becomes more and more important, not only to better understand performance
