临界融合频率（CFF）和时间调制灵敏度函数（TMSF）确定了三只猫使用行为测试程序。CFF的范围为40至55 Hz。灵敏度函数显示出典型的高频衰减，但在15 Hz以下有一些不寻常的特征。与使用相同刺激推导出的人类灵敏度函数的比较表明，在相同的平均亮度和调制深度下，猫能够检测到更高的闪烁率。当目标对于视网膜照明相等时，这种差异较小，但没有消除。
Critical fusion frequency (CFF) and a temporal modulation sensitivity function (TMSF) were determined for three cats using behavioral testing procedures. CFF's ranged from 40 to 55 Hz. The sensitivity functions showed the classic high frequency attenuation but had some unusual features below 15 Hz. Comparisons with the sensitivity function of humans derived with the same stimulus indicated that at the same average luminance and modulation depth, cats were capable of detecting higher rates of flicker. This difference is smaller, but not eliminated, when targets are equated for retinal illumination.
