For sinusoidal gratings, two experiments were carried out to examine relation between simple reaction time and perceptual and response processes. First, the simple reaction time (RT) was measured as a function of grating contrast with spatial frequency as a parameter. Second, contrast threshold was determined as a function of exposure duration (ED). On the basis of the RT-contrast function and the ED-contrast threshold function empirically obtained, the difference between the RT and the ED was… CONTINUE READING
