Beschreibung
According to top-down theories of visual search, only stimuli that match searched-for features of the target capture attention. In many experiments searched-for features are either onsets (sudden appearances) or particular colours. If participants search for an onset target, only an onset cue should capture attention, but a colour cue should not. It remains unclear, whether onsets truly form an independent searched-for feature. In past studies the matching of colours and onsets was typically confounded. In 4 experiments, we used the paradigm by Folk, Remington, and Johnston (1992) to study this question. While searching for a white onset target, white onset cues and white colour cues captured attention to a similar extent (Experiment 1). Also, red and white onset cues captured attention if participants searched for either a white (Experiment 2a) or a red (Experiment 2b) onset target. In Experiment 3, we used red and white colour cues while participants searched for a white onset target. Finally, we also studied capture of equiluminant dark or light colour cues during the search for a light (Experiment 4a) or dark (Experiment 4b) onset target. With the results of these experiments, we discuss the role of colour information during top-down search for onsets.| Zeitraum | 11 Aug. 2014 |
