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 described by Frohlich. (C) 1999 Elsevier Science Ltd. All rights reserved.
