However, only a few studies have examined the impact of social interactions on group dynamics in team sports and their influence on team performance. This study aimed to investigate the effects of game performance pressure on the gaze behavior within social interactions between beach volleyball players during game-like situations. Therefore, 18 expert beach volleyball players conducted a high and a low game performance pressure condition while wearing an eye tracking system. The results indicate that higher game performance pressure leads to more and longer fixation on teammates’ faces. A higher need for communication without misunderstandings could explain this adaptation. The longer and more frequent look at the face could improve the receiving of verbal and non-verbal information of the teammate’s face. Further, players...

Using three-dimensional (3D) scanner technology provides the opportunity to understand more about morphological changes throughout childhood with higher resolution and potentially more relevant 3D shape measures. This is important to advance the prevailing arguments about the typical development of children’s feet and inform the development of appropriate clinical measures. 3D shape descriptors derived from 3D scanning can be used to quantify changes in shape at each point of the 3D surface. The aim of this study was to determine whether 3D shape descriptors derived from 3D scanning data can identify differences in foot morphology between children of different ages. Methods Fifteen children were recruited from three age groups (...

The focus of attention has been shown to be important in fast team-sport games. The authors developed a method that measures the extent of the attentional focus and perceptual capabilities during performance of a sport-specific task. The participants were required to judge different player configurations on their left and right sides with varying visual angles between the stimuli. In keeping with the notion that the focus of attention is smaller than the visual field, attentional performance was poorest at the wider viewing angles compared with perceptual performance. Moreover, the team-sport players were better able to enlarge their attentional focus and make correct decisions more frequently than individual athletes, particularly when a motor response was required. The findings provide a new perspective, dissociating the attentional and perceptual processes tha...

In Experiment 1, those with higher and lower skill levels in anticipation predicted the throw direction of an opponent who wore a garment designed to disguise kinetic-chain information. Higher skill anticipators were more adversely affected by the disguise garment than the lower skill anticipators, demonstrating that disguise removed the anticipation advantage. In Experiment 2, using the same occlusion methodology, the effect of deception was examined using 2 garments designed to create visual illusions of motion across the proximal-to-distal sequence of the thrower's action and compared with a white-garment control. Performances for the deceptive garments were reduced relative to the control garment at the earliest occlusion points for the rightmost targets, but this effect was reversed for the leftmost targets at the earliest occlusion point, suggesting that the visual illusion ga...

To inform theory that underpins clinical practice, there is a clear need to revisit our understanding of how the foot develops. Hand-held 3-D scanners provide portability and allow researchers to collect data about foot development in the children’s natural environment. However, there are methodological challenges to consider: scanning the plantar surface in a static weight-bearing position, the children’s ability to remain static for the duration of the scanning and software capabilities. The aim of this study was to determine the reliability of using a hand-held scanner to capture children’s foot shape and size. For this study, 15 children aged two years (Group 1: n=5), five years (Group 2: n=5) and seven years (Group 3: n=5) were recruited. Children stood barefoot in a comfortable bipedal stance, on a Perspex platform of 550mm height. Their feet were scanned three times, including the pla...

Understanding this process requires 3-dimensional (3-D) scanning technology [1]-[4]. Providing robust data on the development of the paediatric foot shape will help clinicians understand the typical trajectory of the foot and foot shape which could help inform understanding of how paediatric foot pathologies develop. The collection of this data requires the development of a normative data set and will involve scanning a high number of feet, across a range of ages. Hand-held 3-D scanners provide the portability required to achieve this as they allow researchers to collect data in the children’s natural environment. However, there are methodological challenges to consider (e.g. static weight bearing position). To determine the reliability of our scanning method and analysis, 15 children were recruited, five from each age group (two, five and seven y...
