In the 'flash-lag' effect, a static object that is briefly flashed next to a moving object appears to lag behind the moving object. A flash was put up next to an intersection that appeared to be moving clockwise along a circular path but was actually moving counterclockwise [the chopstick illusion; Anstis, 1990, in AI and the Eye Eds A Blake, T Troscianko (London: John Wiley) pp 105 117; 2003, in Levels of Perception Eds L Harris, M Jenkin (New York: Springer) pp 90 93]. As a result, the flash appeared displaced clockwise. This was appropriate to the physical, not the subjective, direction of rotation, and it suggests that the flash-lag illusion occurs early in the visual system, before motion signals are parsed into moving objects.
在“闪光滞后”效应中，一个静态物体在一个移动物体旁边短暂闪烁时，看起来会落后于该移动物体。在一个看起来沿圆形路径顺时针移动但实际上是逆时针移动的交叉点旁边设置了一次闪光[筷子错觉；安斯蒂斯，1990年，载于《人工智能与视觉》，A·布莱克、T·特罗西安科编（伦敦：约翰·威利出版社），第105 - 117页；2003年，载于《感知层次》，L·哈里斯、M·詹金编（纽约：施普林格出版社），第90 - 93页]。结果，闪光看起来顺时针移位了。这与旋转的物理方向而非主观方向相符，这表明闪光滞后错觉在视觉系统中发生得很早，在运动信号被解析为移动物体之前。
