Verghese和Stone（1995）表明，通过分组减少感知到的物体数量也会降低客观表现。Shams，Kamitani和Shimojo（2000）表明，伴随着多次蜂鸣声的单次闪光似乎会闪烁不止一次。我们表明，客观的方向歧视的性能完全取决于感知的闪光次数，独立的蜂鸣声和闪光的实际数量。因此，知觉分析的单位似乎是一个被知觉的事件，与它是如何被诱发的无关。
Verghese and Stone ( 1995) showed that reducing the perceived number of objects by grouping also reduces objective performance. Shams, Kamitani, and Shimojo ( 2000) showed that a single flash accompanied by multiple beeps appears to flash more than once. We show that objective orientation-discrimination performance depends solely on the perceived number of flashes, independent of the actual number of beeps and flashes. Thus the unit of perceptual analysis seems to be a perceived event, independent of how it is induced.
