Trotz intensiver Forschung ist noch nicht völlig klar, wie die Verlagerung von Aufmerksamkeit von top-down und bottom-up Faktoren beeinflusst wird. In dieser Arbeit untersuchen wir, ob achromatische Farbe (hell und dunkel) zur top-down Kontrolle von Aufmerksamkeit verwendet werden kann. In zwei Experimenten suchten Versuchspersonen (N = 32) nach hellen (Experiment 1) oder dunklen (Experiment 2) plötzlich auftauchenden Zielreizen. Gemäß der Hypothese der zielreizabhängigen Verlagerung von Aufmerksamkeit wird die Aufmerksamkeit nur von Hinweisreizen angezogen, die aufgabenrelevante Merkmale besitzen, während Hinweisreize mit aufgabenirrelevanten Merkmalen die Aufmerksamkeit nicht anziehen. Es zeigte sich, dass nur Hinweisreize mit der gleiche...
