在实验室中，视觉搜索通常是使用统一的背景进行研究的。这与日常生活中的搜索形成了鲜明对比，在日常生活中，潜在的搜索项目出现在更复杂的背景下。在本研究中，我们考察了在物体容易与背景分离的条件下，背景复杂性对并行视觉搜索的影响。目标-分心物体的相似度足够低，以至于搜索可以并行展开，以反应时间为索引，反应时间随集合大小对数增加。结果表明，当背景相对简单(有水元素的沙滩)时，搜索效率与使用固体背景的搜索相当。当背景更复杂(儿童卧室或棋盘)时，对数搜索斜率比在坚实背景上的搜索更大，特别是在目标-分心物体相似度更高的情况下。根据视觉搜索的不同理论对结果进行了讨论。有人提出，干扰物之间出现的复杂视觉信息通过削弱项目间相互作用的强度来减缓个体干扰物拒绝时间。
In the laboratory, visual search is often studied using uniform backgrounds. This contrasts with search in daily life, where potential search items appear against more complex backgrounds. In the present study, we examined the effects of background complexity on a parallel visual search under conditions where objects are easily segregated from the background. Target–distractor similarity was sufficiently low such that search could unfold in parallel, as indexed by reaction times that increase logarithmically with set size. The results indicate that when backgrounds are relatively simple (sandy beach with water elements), search efficiency is comparable to search using a solid background. When backgrounds are more complex (child bedroom or checkerboard), logarithmic search slopes increase compared to search on solid backgrounds, especially at higher levels of target–distractor similarity. The results are discussed in terms of different theories of visual search. It is proposed that the complex visual information occurring in between distractors slows down individual distractor rejection times by weakening the strength of interitem interactions.(PsycInfo Database Record (c) 2024 APA, all rights reserved)
