视觉搜索研究通常假设有精确的目标信息来指导搜索，通常是准确目标的图片。然而，在真实的世界中的搜索目标通常被分类地定义并且具有不同程度的视觉特异性。在五个目标预览条件下，我们操纵的目标视觉信息的可用性在搜索任务中常见的现实世界的对象。预览是：目标的图片、目标的抽象文本描述、精确文本描述、抽象+彩色文本描述或精确+彩色文本描述。随着信息被添加到目标预览中，指导通常会增加。我们的结论是，用于搜索指导的信息不需要局限于目标的图片。虽然一般不太精确，但视觉信息可以从目标标签中提取并加载到工作记忆中，这些信息也可以用于指导搜索。
Visual search studies typically assume the availability of precise target information to guide search, often a picture of the exact target. However, search targets in the real world are often defined categorically and with varying degrees of visual specificity. In five target preview conditions we manipulated the availability of target visual information in a search task for common real-world objects. Previews were: a picture of the target, an abstract textual description of the target, a precise textual description, an abstract + colour textual description, or a precise + colour textual description. Guidance generally increased as information was added to the target preview. We conclude that the information used for search guidance need not be limited to a picture of the target. Although generally less precise, to the extent that visual information can be extracted from a target label and loaded into working memory, this information too can be used to guide search.
