Skilled perceptual-cognitive performance is assumed to require superior anticipation, yet few researchers have explored how individual differences in processing measures mediate superior performance, particularly when characteristics of the task are systematically changed from trial to trial. This study examined how advance cue information influences anticipation using a simulated cricket batting task. Skilled (n = 10) and less skilled (n = 10) batters moved in response to life-size video images of 36 deliveries by fast and spin bowlers. Skilled participants (mean 37.3, SD 2.8 mm) were significantly more accurate at anticipating ball position as it passed through the strike zone than less skilled batters (mean 48.9, SD 5.9 mm, p < 0.05). Skilled batters fixated on central areas of the body and searched more locations (p < 0.05). Batters used fixations of longer duration and focused more on the ball and hand when viewing spin compared to fast bowlers (both p < 0.05). Visual behaviour is constrained by the task parameters and participant skill level. An analysis of immediate retrospective reports and eye fixations indicated that skilled batters search and encode scenes at a richer and more sophisticated level than less skilled players.
熟练的感知认知表现被认为需要卓越的预判能力,但很少有研究探讨加工测量中的个体差异如何介导卓越表现,尤其是当任务特征在每次试验中系统地变化时。本研究使用模拟板球击球任务,考察了提前提示信息如何影响预判。熟练击球手(n = 10)和不太熟练的击球手(n = 10)对快速投球手和旋转投球手投出的36次投球的真人大小视频图像做出反应。熟练参与者(平均37.3,标准差2.8毫米)在预判球通过击球区时的位置方面比不太熟练的击球手(平均48.9,标准差5.9毫米,p < 0.05)显著更准确。熟练击球手注视身体的中心区域,搜索的位置更多(p < 0.05)。与快速投球手相比,击球手在观看旋转投球时注视持续时间更长,更多地关注球和手(均p < 0.05)。视觉行为受任务参数和参与者技能水平的限制。对即时回顾报告和眼动注视的分析表明,熟练击球手比不太熟练的击球手在更丰富、更复杂的水平上搜索和编码场景。
