One of the oldest questions in experimental psychology concerns perception of simultaneous events, particularly when input arrives through different sensory channels (sight / sound or touch / sound). How far apart in time must two events be to be perceived as sequential? This paper reports preliminary data from a cross-modal simultaneity task designed for ecological validity. Results indicate a smaller threshold for successiveness than that found in previous experiments, which used more artificial tasks. The present findings are relevant to theories of time, order and perception.
