视觉搜索是研究一系列关于感知和注意力问题的流行工具，这要归功于基本范式可以轻松控制和操纵。虽然搜索任务通常被认为是视觉科学的一个子领域，但它比大多数其他感知任务要复杂得多，其中策略和决策扮演着重要但被忽视的角色。在这篇综述中，我们简要地描述了一些重要的理论进展的感知和注意力，已经从研究视觉搜索的信号检测和引导搜索框架。在大多数情况下，搜索还涉及执行一系列眼球运动。我们认为，了解偏见，惯例和策略的贡献，视觉搜索性能在多个固定将导致这些决策相关的过程，以及它们如何与感知和注意力相互作用的新见解。我们还强调了被忽视的潜在变化，无论是内部和搜索之间，有助于我们的视觉搜索的理解。令人兴奋的挑战将是解释由这些众多因素及其相互作用引起的搜索性能的变化。最后，我们总结了一些建议，未来的研究可以解决这些挑战，推动该领域的发展。
Visual search is a popular tool for studying a range of questions about perception and attention, thanks to the ease with which the basic paradigm can be controlled and manipulated. While often thought of as a sub-field of vision science, search tasks are significantly more complex than most other perceptual tasks, with strategy and decision playing an essential, but neglected, role. In this review, we briefly describe some of the important theoretical advances about perception and attention that have been gained from studying visual search within the signal detection and guided search frameworks. Under most circumstances, search also involves executing a series of eye movements. We argue that understanding the contribution of biases, routines and strategies to visual search performance over multiple fixations will lead to new insights about these decision-related processes and how they interact with perception and attention. We also highlight the neglected potential for variability, both within and between searchers, to contribute to our understanding of visual search. The exciting challenge will be to account for variations in search performance caused by these numerous factors and their interactions. We conclude the review with some recommendations for ways future research can tackle these challenges to move the field forward.
