疏忽视盲是一种引人注目的现象,在这种现象中,视野中的显著物体由于意外而被忽视,注意力集中在其他地方。意外物体的几个属性,如大小和生命,已被证明会影响无意视盲的概率。目前还不清楚移动的意外物体的速度是否或如何影响无意视盲。我们证明,如果意外的物体移动得更慢,则无意视盲率会显著降低,这表明它仅仅是物体的暴露时间,而不是由更高的速度可能引起的更高的显着性,这决定了其检测的可能性。其他解释可以排除:效果不是基于弹出效果所产生的不同的运动速度相对于主要任务的刺激(实验2),也不是基于一个更高的显着性缓慢移动的意外对象(实验3)。
Inattentional blindness is a striking phenomenon in which a salient object within the visual field goes unnoticed because it is unexpected, and attention is focused elsewhere. Several attributes of the unexpected object, such as size and animacy, have been shown to influence the probability of inattentional blindness. At present it is unclear whether or how the speed of a moving unexpected object influences inattentional blindness. We demonstrated that inattentional blindness rates are considerably lower if the unexpected object moves more slowly, suggesting that it is the mere exposure time of the object rather than a higher saliency potentially induced by higher speed that determines the likelihood of its detection. Alternative explanations could be ruled out: The effect is not based on a pop-out effect arising from different motion speeds in relation to the primary-task stimuli (Experiment 2), nor is it based on a higher saliency of slow-moving unexpected objects (Experiment 3).
