摘　　要：考察篮球运动员在多目标视觉追踪任务中的表现。专家组为篮球后卫、中锋和前锋各14人,新手组为篮球专选学生14人,实验运用多目标追踪和变化检测范式考察各组别在不同目标数条件下的追踪正确率。结果表明:随着目标数增多,专家组的追踪正确率与新手组的差异逐渐显著,出现显著性差异的顺序依次为后卫、中锋和前锋。专家组组块化的效率高于新手组;后卫的多目标追踪能力具有非常明显的优势,中锋略好于前锋。This study aimed to explore the performance of basketball players in multi-object tracking task.In the experiment,experts were 14 guards,14 centers,14 forwards and novices were 14 basketball special course undergraduates.Using multi-object tracking and change detection paradigm,these studies investigated the basketball players＇ correct rates in visual tracking task.The results showed that significant differences of tracking correct rates gradually began to emerge with increasing number of objects.Emerging difference is in sequence as： guards,centers and forwards.Experts＇ chunking strategies are more efficient than novices.Guards have an obvious advantage of multi-object tracking ability,followed by centers and forwards.
