中文摘要：

通过3个实验分别考察了视觉和听觉任务对同时进行的多目标追踪任务干扰程度的差异,以及当视觉与听觉任务的信息加工与多目标追踪的身份特征相一致时,视觉与听觉任务是否会对多目标追踪产生促进作用。在控制眼动的情况下,听觉任务对多目标追踪的干扰程度大于视觉任务;而在不控制眼动的情况下,听觉任务对多目标追踪的干扰程度小于视觉任务。说明多目标追踪过程既要占用编码阶段的视觉注意资源,又要占用中央加工阶段的中央注意资源。当视觉或听觉数字判断任务中的数字与多身份追踪任务中目标的数字身份相一致时,该相容性会对追踪表现产生促进作用并降低两任务间的干扰程度。这是由于追踪过程中目标的数字身份被储存在视觉工作记忆中,节约了用于数字加工的认知资源,从而促进了两项任务的表现。最后,对多目标追踪中的注意分配机制进行了讨论。

英文摘要：

Multiple Object Tracking （MOT） developed by Pylyshyn and Storm （1988） has been widely used in the study of capacity-limited and object-based attention. Many researchers interested in finding out whether or not the tracking processes in MOT occupy attentional resource and what type of resource is used. The typical paradigm used in this line of research is dual-task paradigm. Participants were asked to perform a visual or auditory task and the MOT task simultaneously. MOT performance was interfered by both the visual and the auditory task. However, the interference of visual task and auditory task with MOT occurred at different levels. The previous studies demonstrated that the MOT task and visual task occupy visual attention resources.＆amp;nbsp;Although the MOT task and auditory task don’t occupy visual attention resources, they share more central attention resources （such as executive function）. Multiple Identity Tracking （MIT） is a variant of MOT, in which each object carries a unique identity. The previous studies also included both visual or auditory task and MIT task, but those studies have not examined how the visual/auditory task affects the MIT task when the two tasks shared the same properties. The current study included 3 experiments and aimed to investigate the influence of a visual or auditory task on either MOT or MIT task. The first two experiments manipulated participants’ eye movement to compare the different effects of visual task and auditory task on MOT performance. The result of experiment 1A showed that the auditory task interfered more with MOT than did the visual task when eyes were fixated at the center of the screen. However, the auditory task yielded less interference with MOT when there was no eye movement control in experiment 1B. The results indicated that the tracking processes in MOT not only occupy visual attention resources, but also occupy central attention resources （such as executive function）. The experiment 2 applied visual and auditory digit judgmen
