This study examined differences in decision-making time and accuracy as attributes of speed discrimination between participants skilled and less skilled in ball games. A total of 130 men, ages 18 to 28 years (M = 21.2, SD = 2.6), participated. The athlete sample (skilled group) comprised Estonian National League volleyball (n = 26) and basketball players (n = 27). The nonathlete sample (less skilled group) included 77 soldiers of the Estonian Defence Force with no reported top level experience in ball games. Speed-discrimination stimuli were images of red square shapes presented moving along the sagittal axis at four different virtual velocities on a computer (PC) screen which represented the frontal plane. Analysis indicated that only decision-making time was significantly different between the elite athlete and nonathlete groups. This finding suggests a possible effect of ball-game skills for decision-making time in speed discrimination.
