使用基于视频的时间遮挡测试测量了职业棒球击球手(N = 105)对球场类型和位置的视觉预期，并与他们的棒球击球统计数据进行了关联。参与者观看了熟练棒球投手在投球时被暂时遮挡的比赛中画面，以及投球后80ms和200ms的画面。参与者对音高类型和位置进行了书面预测。结果表明，对组合投球类型的预期和投球后80ms的位置与投篮命中率呈显著正相关(r = .21)。仅在投球后200ms的投球类型预期与三振之间存在显著的负相关(r = −.28)，表明较高的预测与较少的错误挥杆选择相关。此外，对投球后200ms投球类型的预期与上垒率(r = .23)和保送三振比(r = .25)呈显著正相关。这些小的关系与我们预测的击球统计数据是一致的，可能是由于参与者参加过的联赛的竞争水平的范围。这一发现进一步加深了对角色视觉预期对棒球击球比赛表现的影响的理论和应用知识。研究结果还表明，比赛镜头可以用来评估和潜在地训练视觉预期技能，这对运动员和体育组织中的高绩效支持人员非常有价值。
Professional baseball batters’ (N = 105) visual anticipation of pitch type and location were measured using a video-based temporal occlusion test and correlated with their baseball batting statistics. Participants watched in-game footage of skilled baseball pitchers that was temporally occluded at the point of ball release, and at 80 ms and 200 ms after ball release. Participants made written predictions of pitch type and location. Results indicated there was a significant positive correlation between anticipation of combined pitch type and location 80 ms after ball release with slugging percentage (r = .21). There was a significant negative correlation between anticipation of pitch type alone 200 ms after ball release and strikeouts (r = −.28), indicating higher prediction is associated with fewer incorrect swing choices. Furthermore, there was a significant positive correlation between anticipation of pitch type alone 200 ms after ball release and on-base percentage (r = .23) as well as walk-to-strikeout ratio (r = .25). These small relationships are consistent to the batting statistics we predicted and can be due to the range of competitive levels in the leagues the participants had played. The findings further theoretical and applied knowledge of the role visual anticipation contributes to baseball batting game performance. The findings also suggest that game footage can be used to assess and potentially to train visual anticipation skill, which is highly valuable for athletes and high performance support staff in sporting organizations.
