Reaction times to motion onset and motion detection thresholds reflect the properties of bilocal motion detectors.

Several different psychophysical paradigms are used to study human motion perception. A unifying framework for the interpretation of all data is lacking. As a step towards a universal model for motion detection we show that previously published reaction times to motion onset and thresholds for the detection of periodic motion may be derived from the velocity dependent properties of bilocal motion detectors of the Reichardt correlator type. Thus, these data sets seem to support the concept of bilocal motion detectors.
