摘要

传统的视觉搜索任务并不直接针对注意力,其核心操作 "集合大小"--显示项目的数量--会带来刺激混淆,从而妨碍解释。然而,替代方法并没有被广泛采用,这或许反映了它们的复杂性、假设或间接注意取样。在这里,一种新的程序--"注意位置和大小"(ATLAS)任务使用探针显示来跟踪搜索过程中的注意位置、广度和引导。虽然大多数探针显示由六个项目组成,但参与者只报告他们认为自己感知最清晰的单个项目--即注意力 "峰值"。通过对不同 "选择集 "中的峰值进行取样,可以分析出搜索过程中注意力窗口的大小和位置。这些指数似乎可以区分狭义注意和广义注意,对出现注意的项目对发出信号,并跟踪随时间演变的注意引导。ATLAS 设计用于区分五种关键的搜索模式:无引导的连续搜索、有引导的连续搜索、有局部引导的对 "团块 "的无引导注意,以及有或无引导的广泛平行注意。这项初步研究仅使用了一组高度规则的刺激物,但其更广泛的潜力仍有待研究。

ATLAS: Mapping ATtention’s Location And Size to probe five modes of serial and parallel search

Conventional visual search tasks do not address attention directly and their core manipulation of ‘set size’ – the number of displayed items – introduces stimulus confounds that hinder interpretation. However, alternative approaches have not been widely adopted, perhaps reflecting their complexity, assumptions, or indirect attention-sampling. Here, a new procedure, the ATtention Location And Size (‘ATLAS’) task used probe displays to track attention’s location, breadth, and guidance during search. Though most probe displays comprised six items, participants reported only the single item they judged themselves to have perceived most clearly – indexing the attention ‘peak’. By sampling peaks across variable ‘choice sets’, the size and position of the attention window during search was profiled. These indices appeared to distinguish narrow- from broad attention, signalled attention to pairs of items where it arose and tracked evolving attention-guidance over time. ATLAS is designed to discriminate five key search modes: serial-unguided, sequential-guided, unguided attention to ‘clumps’ with local guidance, and broad parallel-attention with or without guidance. This initial investigation used only an example set of highly regular stimuli, but its broader potential should be investigated.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
