Effects of high-contrast simultaneous masking gratings on the temporal sensitivity of signal gratings were measured as a function of masking spatial frequency, where temporal sensitivity was defined as the reciprocal of the minimum exposure duration required for a signal to be detected. The sensitivity of signal gratings was shown to be facilitated when signal frequencies and masking frequencies were separated by more than about 2 octaves but inhibited when the two frequencies were not separated this much. The results were quantitatively different from the results obtained in terms of contrast sensitivity. Psychometric functions on grating detection were shown to become steeper when the temporal sensitivity was enhanced and less steep when it was decreased.
测量了高对比度同时掩蔽光栅对信号光栅时间敏感性的影响，并将其作为掩蔽空间频率的函数，其中时间敏感性定义为检测到信号所需的最小曝光持续时间的倒数。当信号频率和掩蔽频率相差超过约2个八度时，信号光栅的敏感性得到促进，但当两个频率相差不足此值时则受到抑制。这些结果在定量上与基于对比度敏感性获得的结果不同。光栅检测的心理测量函数在时间敏感性增强时变得更陡峭，而在时间敏感性降低时则变得不那么陡峭。
