据报道，一项实验检验了注意力和专业知识在多目标跟踪中的作用。它比较了专业雷达操作员（专家）和本科生（新手）获取和跟踪干扰物中随机移动目标子集并对探测器做出适当响应的能力。参与者单独承担这项跟踪任务，然后与第二项数字分类任务结合起来。对于一半的参与者来说，第二个任务在跟踪任务的目标获取阶段之前开始，而对于其余的参与者来说，第二个任务是在跟踪任务的目标获取阶段之后开始的。结果表明专家在所有条件下都比新手更好。此外，两种双重任务条件之间的结果比较表明，注意力资源对新手和专家的目标跟踪都有贡献，但似乎只对新手的目标获取做出贡献。研究结果对多目标跟踪理论具有重要意义；雷达操作员的选择；以及对其训练的监控。版权所有 (C) 2004 John Wiley Sons, Ltd.
An experiment is reported examining the role of attention and expertise in multiple target tracking. It compares the ability of professional radar operators (experts) and undergraduate students (novices) to acquire and track subsets of randomly moving targets amongst distractors, and respond appropriately to a probe. Participants under-took this tracking task alone then, subsequently, in conjunction with a second, digit categorization task. For half the participants, the second task commenced prior to the tracking task's target acquisition phase, for the remainder after. Results suggest experts are better than novices across all conditions. Further, a comparison of results between the two dual task conditions indicates that attentional resources make a contribution to target tracking in both novices and experts, but only appear to make a contribution to target acquisition in novices. The results have implications for theories of multiple target tracking; the selection of radar operators; and the monitoring of their training. Copyright (C) 2004 John Wiley Sons, Ltd.
