Determination of the threshold of simultaneity and temporal order using the "step-ladder" method.
The article considers the sensitivity of the mechanisms for perceiving simultaneity and temporal order. A method similar to the psychophysical "staircase" method is used for determining the thresholds of the perception of simultaneity and temporal order. The simultaneity and temporal order thresholds are measured for two levels of visual adaptation of the subjects. Two clearly distinguishable thresholds are established: simultaneity threshold and temporal order threshold. The threshold values for simultaneity and temporal order are preserved, irrespective of the adaptation level, which suggests that the general illumination does not affect the mechanisms for perceiving simultaneity and temporal order.
