Zusammenfassung

Usually we assume that the central nervous system preserves temporal sequences. Here we show that moving objects-in the context of behaviour
often dangerous ones-are seen with a shorter latency than stationary (flashed) objects. In addition moving objects are deblurred. Two mechanisms contribute to
this functional specialisation: cue-induced visual focal attention and metacontrast. Under unnatural conditions these mechanisms lead to an optical illusion first
