The discrepancy between the actual flicker frequency and the perceived rate was investigated. We tried to quantify the subjective rate of successive visual flicker by matching it with a second stimulus, the audio flutter. The wave form of each stimulus employed in the present study was sinusoidal. The auditory stimulus employed as a reference was a pure tone which was frequency-modulated by a sine wave. The perceived rate of flicker increases approximately in direct proportion to the frequency presented when target size is small and tends to be lower than the actual rate when target size is large. Perceived rate never exceeds approximately 10 Hz regardless of the presented flicker frequency or the luminance of the target. These tendencies are observed commonly in the fovea and in the periphery of the retina.
研究了实际闪烁频率与感知频率之间的差异。我们试图通过将连续视觉闪烁的主观频率与第二种刺激（音频颤动）相匹配来对其进行量化。本研究中使用的每种刺激的波形均为正弦波。用作参考的听觉刺激是由正弦波进行频率调制的纯音。当目标尺寸较小时，闪烁的感知频率大致与呈现的频率成正比增加，而当目标尺寸较大时，感知频率往往低于实际频率。无论呈现的闪烁频率或目标的亮度如何，感知频率都不会超过约10Hz。这些趋势在视网膜中央凹和周边区域普遍存在。
