在自然场景的彩色图像中呈现的目标物体在扫视过程中被删除或旋转，或从目标物体或到场景的控制区域。尽管有指示要记住场景的细节并监视对象的变化，但观众经常无法注意到这些变化。然而;未能察觉变化是由另外三个重要因素造成的。首先，随着变化区域与变化前固定点之间的距离减小，精度一般会增加。其次，变化有时一开始是被忽略的，当变化的区域后来被重新定位时，brit随后就注意到了。第三，当一个物体从场景中消失时，如果删除发生在对该物体的扫视过程中，则对该物体消失的检测将大大提高。这些结果表明，注视位置和扫视方向在决定是否检测到变化方面起着重要作用。与之前的研究相比，这似乎可以保留更多的信息。
Target objects presented within color images of naturalistic scenes were deleted or rotated during a saccade to or from the target object or to a control region of the scene. Despite instructions to memorize the details of the scenes and to monitor for object changes, viewers frequently failed to notice the changes. However; the failure to detect change was mediated by three other important factors.. First, accuracy generally increased as the distance between the changing region and the fixation immediately before ol after the change decreased. Second, changes were sometimes initially missed, brit subsequently noticed when the changed region was later refixated. Third, when an object disappear-ed from a scene, detection of that disappearance was greatly improved when the deletion occurred during the saccade toward that object. These results suggest that fixation position and saccade direction play an important role in determining whether changes will be detected. It appears that more information can be retained across views than has been suggested by previous studies.
