“…Experts are able to rapidly extract meaningful chunks of structured information from a visual scene (Helsen and Pauwels 1992;Helsen and Starkes 1999), though the patterns of gaze that underpin these behaviours appear to be very context specific. For instance, skilled athletes may rely on a lower search rate (ie fewer fixations per second) in some decision-making tasks (eg Bard and Fleury 1976;Helsen and Pauwels 1992), but show a higher search rate in other tasks (eg Mann et al 2009;Vaeyens et al 2007a;Williams et al 1994). The ideal search pattern also apparently varies when an identical task-for example, anticipating a soccer pass-is coupled with variations in the number of players in the scene (Williams and Davids 1998;Williams et al 1994).…”

Abstract. The purpose of this study was to investigate the role of central and peripheral vision in expert decision making. A gaze-contingent display was used to selectively present information to the central and peripheral areas of the visual field while participants performed a decision-making task. Eleven skilled and eleven less-skilled male basketball players watched video clips of basketball scenarios in three different viewing conditions: full-image control, moving window (central vision only), and moving mask ( peripheral vision only). At the conclusion of each clip participants were required to decide whether it was more appropriate for the ball-carrier to pass the ball or to drive to the basket. The skilled players showed significantly higher response accuracy and faster response times compared with their lesserskilled counterparts in all three viewing conditions, demonstrating superiority in information extraction that held irrespective of whether they were using central or peripheral vision. The gaze behaviour of the skilled players was less influenced by the gaze-contingent manipulations, suggesting they were better able to use the remaining information to sustain their normal gaze behaviour. The superior capacity of experts to interpret dynamic visual information is evident regardless of whether the visual information is presented across the whole visual field or selectively to either central or peripheral vision alone.

“…Además hay evidencias que sugieren que la información puede ser procesada de forma más rápida por la visión periférica que con la vía fóvea, lo que puede aportar una ventaja significativa cuando los tiempos para decidir son bajos (Vaeyens et al, 2007a), como …”

“…De este modo, una estrategia visual efectiva sería aquella con un menor número de fijaciones visuales, de mayor duración, y pocos movimientos sacádicos (Bard & Fleury, 1976;Vickers, 1988;Abernethy, 1990;Helsen & Starkes, 1999;Savelsbergh et al, 2002;Williams, Singer, & Frehlich, 2002;Vaeyens, Lenoir, Williams, Mazyn, & Philippaerts, 2007a;Vaeyens, Lenoir, Williams, & Philippaerts, 2007b;Reina, Moreno, & Sanz, 2007;Mann et al, 2007), ya que los jugadores dispondrían así de mayor tiempo de procesamiento de la información. Sin embargo, el ratio de bús-queda visual puede variar en función de aspectos como la modalidad deportiva (Williams, Davids, Burwitz, & Williams, 1993;Williams & Davids, 1995), el rol desempeñado (ataque o defensa) (Williams, 2000;Vaeyens et al, 2007a;Afonso, Garganta, McRobert, Williams, & Mesquita, 2012), la cantidad de incertidumbre de la escena (Bard & Fleury, 1976) o la proximidad al objetivo (Roca, Ford, McRobert, & Williams, 2013).…”

ResumenEl objetivo del presente estudio fue analizar el comportamiento visual de las jugadoras de voleibol en una situación de bloqueo basándose en la figura de la colocadora. La muestra quedó compuesta por 29 jugadoras de voleibol (23.10 ± 3.74 años) que competían de manera federada. Se analizó el comportamiento visual de las jugadoras utilizando secuencias de vídeo proyectadas a tamaño real. Las participantes visionaron el mismo número de colocaciones, realizadas por dos jugadoras distintas, de su mismo nivel competitivo. Dentro del comportamiento visual se analizó la duración, núme-ro y orden de las fijaciones visuales, y los movimientos sacádicos. El número medio de fijaciones de las participantes fue de 3.61, con una duración media de 3.56 s. Encontramos un patrón en el comportamiento visual de las participantes del estudio basado en sus fijaciones visuales. Inicialmente las participantes utilizaban la visión periférica para detectar diferentes estímulos de la escena y posteriormente su tendencia fue a utilizar la visión fóvea centrándose en distintas zonas concretas. Las zonas más fijadas por las participantes, de las cuales extraen la información para su toma de decisiones, son fondo (FD) y codo-muñeca (CM) en primer lugar, seguidas de cabeza (CB), balón (BA), hombro-codo (HC), balón-muñeca (BM) y tronco (TR).Palabras clave: comportamiento visual, voleibol, bloqueo. AbstractThe aim of this study was to analyze the visual behavior of the volleyball players in a blocking situation based on the figure of the setter. The sample was composed of 29 volleyball players (23.10 ± 3.74 years). The visual behavior of players was analyzed using video footage projected at 'life-size'. The participants envisioned the same number of placements made by two different players of the same competitive level. Within the visual behavior duration, number and order of visual fixations and saccades were analyzed. The average number of fixations of participants was 3.61, with an average of 3.56 s. We found a pattern in the visual behavior of study participants based on their visual fixations. Initially participants used peripheral vision to detect different stimuli from the scene and later the tendency was to use foveal vision focusing on different specific areas. The most fixed areas set by the participants, of which we extracted the information for decision making, are background (FD) and elbow -wrist (CM) first, followed by head (CB), ball (BA), shoulder -elbow (HC), ballwrist (BM) and trunk (TR).

“…This divergence might be explained due to group's characteristics. Indeed, Vaeyens et al [32] studied differences in responses accuracy between soccer players and non-players [very distinctive groups) and found that the first ones made more accurate decisions. Therefore, the game complexity differs according to the age group and specific experience as left-side attacker, thus requiring the appropriation of decision-making and performance to their play level.…”

Abstract:The purpose of this study was to analyze the procedural knowledge in action, decision-making and performance of the left-side attacker according to age group and specific experience, in women's volleyball. Four Portuguese women's teams participated in the present study: one under-16, one under-18 and two adult teams. A verbal interview protocol was implemented immediately after randomly chosen live game actions. The left-side attackers had to verbally respond to this question immediately following the execution of an attack, in 6 vs. 6 situations in practice. Players' decision-making and performance were analyzed by video images. Procedural knowledge was analyzed trough non-parametric statistics, namely Kruskal-Wallis and Mann-Whitney tests. Decision-making and performance were analyzed through Chi-square (! 2 ) testing. Results showed that adult teams and the more experienced left-side attackers generated more goal concepts and fewer condition concepts, were more often concerned with the opponent and less with teammates. Moreover, no differences in player's performance and decision-making were observed according to age group and experience as left-side attackers. Further research should consider the characterization of the training process, mainly focusing on the tactical contents, as the information provided could provide a better and deeper understanding about the players' tactical development.
