在复合掩膜光栅存在的情况下，测量了光栅靶的检测和识别阈值作为刺激开始异步（SOA）的函数。检测和识别SOA功能都是倒u型的，但它们不是平行的。检测识别比本身是SOA的反向u型函数，即使对于间隔两个八度的刺激，峰值在+20和+60 ms SOA之间（反向掩蔽）。有人认为，这些结果支持假设，根据检测和识别是一系列的过程。
Detection and identification thresholds for grating targets were measured in the presence of a compound mask grating as a function of the stimulus onset asynchrony (SOA). The detection and identification SOA functions are both reversed U-shaped but they are not parallel. The detection-to-identification ratio is itself a reversed U-shaped function of SOA, even for stimuli two octaves apart, with a peak between +20 and +60 ms SOA (backward masking). It is argued that these results support the hypothesis according to which detection and identification are serial processes.
