| contents | In soccer penalty kicks, goalkeepers that orient their arms upward compared to downward can be misperceived as being taller - effectively recreating the Muller-Lyer illusion. The present study elaborates on previous research surrounding a potential illusion-induced bias in penalty kicks. Participants were exposed to goalkeeper configurations within a virtual goal including arms-parallel, arms-down, arms-out and arms-up. They separately judged the perceived size of the goalkeeper, and executed penalty kicks. The perceived size was near fully consistent with the intended illusion. Meanwhile, the penalty kicks indicated wider a horizontal position following arms-out, and lower vertical position following arms-up. Likewise, there was no relation between the biases expressed in perception and action. While goalkeepers can elicit a perceptual illusion, this does not extend to influencing the penalty kick itself. Instead, other contextual cues appeared more relevant including the proximity between the goalkeeper and goalposts, and with it, the available space in the goal. |
