People are most likely to see something if their gaze is directed at it. Thus if they saw something they may be biased towards believing that they had been looking at it. In order to examine whether this is so we asked participants where a target that jumped to a new position every 250 ms had been at a moment indicated by a flash or a tone. The jumping introduced uncertainty about where the target was at the indicated moment, giving room for biases to be expressed. Participants showed a clear preference to select positions that were nearer to where they were looking.
如果人们的目光直接指向某个事物,他们就最有可能看到它。因此,如果他们看到了某样东西,可能就会倾向于相信自己一直在注视着它。为了检验情况是否如此,我们让参与者指出一个每250毫秒就会跳到一个新位置的目标在闪光或音调指示的某个时刻位于何处。这种跳动引入了关于目标在指示时刻位置的不确定性,从而为偏差的表现提供了空间。参与者表现出明显的偏好,即选择更靠近他们注视方向的位置。
