为了检查视觉注意力是否在视野中连续转移，我们测量了观察者在模糊视在运动显示中跟踪移动目标时对不同位置出现的小闪光的敏感度。灵敏度在目标附近达到峰值，并且峰值沿着表观运动路径平滑移动。由于峰值移动速度随着跟踪目标的速度而变化，因此我们得出结论，注意力机制通过连续跟踪目标磁盘来选择位置以促进处理。注意力并不是简单地选择一个位置来进行增强处理，而是根据感兴趣对象的速度来预测其未来的位置。 (C) 2002 Elsevier Science Ltd. 保留所有权利。
To examine whether visual attention shifts continuously across the visual field, we measured sensitivity to a small flash presented at various locations while the observer was tracking a moving target in an ambiguous apparent motion display. The sensitivity peaked near the target and the peak shifted smoothly along the apparent motion path. Since the peak-shift speed varied with the speed of the tracked target, we conclude that the attention mechanism selects the location to facilitate processing by tracking the target disk continuously. Attention does not simply select a location for enhanced processing, but rather predicts the future location of the object of interest based on its velocity. (C) 2002 Elsevier Science Ltd.
