Perception of Temporal Order of Flashing Lights as a Navigation AID
Abstract
A set of lights flashing either simultaneously or sequentially was tested for effectiveness as a navigation beacon. The temporal interval between sequential flashes required for the perception of non-simultaneity averaged about 10 msec. The change in temporal interval required to see a difference increased as the initial temporal interval increased; it averaged about 18 msec when the lights were initially simultaneous to about 26 msec when the initial temporal interval was 33 msec. The temporal interval between the flashing lights required to perceive non-simultaneity appeared to increase when the lights were very dim and appeared to decrease when the viewing distance increased, although neither change reached statistical significance.
