The purpose of this study was to investigate the differences in the ability of soccer goalkeepers to anticipate the direction of penalty kicks. Six elite goalkeepers with more than 10 years of experience participated in this experiment. Participants were required to press a reaction button as soon as they could estimate the direction of the ball while watching videos of penalty kicks. For this ...

According to a widely cited finding by Ellis and Stark (1978 Perception 7 575-581), the duration of eye fixations is longer at the instant of perceptual reversal of an ambiguous figure than before or after the reversal. However, long fixations are more likely to include samples of an independent random event than are short fixations. This sampling bias would produce the pattern of results also ...

PURPOSE To review outcome after arthroscopic fixation for acute acromioclavicular (AC) joint dislocation using the TightRope device. METHODS Records of 15 men and 2 women aged 19 to 52 (mean, 35) years who underwent arthroscopic fixation using the TightRope device for acute (<3 weeks) AC joint dislocation of Rockwood type III (n=6), type IV (n=1), and type V (n=10) were reviewed. Outcome was ...

Artificial scotomas positioned within peripheral dynamic noise fade perceptually during visual fixation (that is, the surrounding dynamic noise appears to fill-in the scotoma). Because the scotomas' edges are continuously refreshed by the dynamic noise background, this filling-in effect cannot be explained by low-level adaptation mechanisms (such as those that may underlie classical Troxler fad...

background: white button mushroom (agaricus bisporus) is one of the most sensitive agricultural crops after harvesting and its antioxidant properties tend to decrease during post-harvest storage with the passage of time. objectives: the possible role of exogenous application of malic acid as dipping treatment on bioactive components and antioxidant properties of sliced white button mushroom dur...
