Abstract: | Past studies have suggested that a new object can involuntarily capture attention in a visual search task (Yantis & Jonides, 1984 Yantis, S. and Jonides, J. 1984. Abrupt visual onsets and selective attention: Evidence from visual search. Journal of Experimental Psychology: Human Perception and Performance, 10: 601–621. Crossref], PubMed], Web of Science ®] , Google Scholar]). However, trials in these experiments usually begin with abrupt onsets that are considered to signal new objects; thus, there may be a bias toward paying attention to new objects. We examine whether new objects can still capture attention when this bias is excluded, using an inattentional blindness task. Our results showed that when the trials began with new objects, a new object captured attention. When new objects were totally irrelevant and all top-down settings for new objects were prevented, a new object did not capture attention. Our findings argue against the view that new objects capture attention in a purely stimulus-driven fashion. |
