The effects of relative priority of attentional resources allocated to simultaneous peripheral and foveal tasks, response sequence to the tasks, and order to testing with two levels of foveal cognitive loading on tunnel vision were studied with 32 Chinese undergraduates. Two levels of foveal condition were used for the foveal task while the peripheral task required a single-target detection. Performance decrement value and a significant interaction of levels x eccentricities indicated that tunnel vision was most prominent when the foveal task was primary. Greater magnitude of tunnel vision was obtained when the more difficult foveal task was tested prior to the no-foveal-load condition. Responding sequence to the tasks was nonsignificant.
以32名中国大学生为被试，研究了分配给同时进行的外周和中央凹任务的注意资源的相对优先级、对任务的反应顺序以及在两种中央凹认知负荷水平下的测试顺序对管状视野的影响。中央凹任务采用两种中央凹条件，而外周任务要求进行单目标检测。绩效下降值以及水平×偏心率的显著交互作用表明，当中央凹任务为主时，管状视野最为突出。在无中央凹负荷条件之前先测试较难的中央凹任务时，获得的管状视野幅度更大。对任务的反应顺序不显著。
