两个静止的和空间分离的视觉刺激，在时间上短暂而连续地出现，产生频闪运动，其生动度是刺激开始的非同步性的u形函数。轮廓掩蔽也已知发生在这样的刺激条件下。研究结果表明，轮廓掩蔽只局限于第一个刺激，它与后对比一样，是刺激开始时异步的后u型函数。一个简单的模型，基于已知的心理物理和神经生理特性，被提出来解释这些结果。
Two stationary and spatially separated visual stimuli, presented briefly and successively in time, are known to produce stroboscopic motion whose vividness is a U-shaped function of the stimulus onset asynchrony. Contour masking is also known to occur under such stimulus conditions. The findings show that the contour masking is confined to only the first stimulus and that it, like metacontrast, is a backward U-shaped function of the stimulus onset asynchrony. A simple model, based on known psychophysical and neurophysiological properties, is proposed to explain these results.
