Inattentional blindness methods allow for an unobtrusive measure of the spatial distribution of attention; because subjects do not expect the critical object, they have no reason to devote attention to task-irrelevant regions in anticipation of it. We used inattentional blindness to examine the spatial allocation of attention in an interactive game in which subjects navigated through a dynamic environment and avoided hazards. Subjects were most likely to notice unexpected objects in the areas with the greatest risk of contact with a hazard, and less likely to notice equally proximal objects in inaccessible areas of the display or areas in which hazards no longer posed a threat. These results suggest that both the content of the environment and how a subject can interact with it influence the spatial allocation of attention.
无意视盲方法能够对注意力的空间分布进行一种不显眼的测量;由于受试者不会预期关键物体的出现,所以他们没有理由为了预期该物体而将注意力投入到与任务无关的区域。我们运用无意视盲来研究一款互动游戏中注意力的空间分配情况,在该游戏中,受试者要在动态环境中导航并避开危险。受试者最有可能在与危险接触风险最大的区域注意到意外物体,而在显示屏上无法到达的区域或危险不再构成威胁的区域,他们注意到同样距离较近物体的可能性较小。这些结果表明,环境的内容以及受试者与环境的交互方式都会影响注意力的空间分配。
