内容記述 | The critical fusion frequency (CFF) is a threshold that represents the temporal limits of the human visual system. If two flickering stimuli with equal subjective luminances are presented simultaneously at different locations, the CFF is the temporal frequency above which they cannot be distinguished. However, when the stimuli are presented sequentially at the same position, a transient twinkle can be perceived around the moment of the changeover. To investigate the mechanism underlying this transient twinkle perception (TTP), we independently manipulated the luminance contrast and temporal frequency of the flicker, as well as the inter-stimulus interval (ISI). We found that TTP was greater as the luminance step was larger, it was stably perceived for flicker frequencies up to 200 Hz, and it was robust for all ISIs if flicker frequencies were below 250 Hz. For 250 and 300 Hz flicker, TTP was attenuated in the condition that 1-frame and 2-frame ISIs were inserted. These results can be explained by a simple filtering model that TTP occurs if the temporal change in a weighted moving average of stimulus luminance exceeds a certain threshold. TTP gives additional evidence that human visual system can detect the transient change of flicker stimuli at much higher temporal frequency than the CFF, by averaging mechanism of luminance. | |||||
