虽然它已经众所周知，视觉线索影响随后的视觉刺激的感知，相对知之甚少的线索本身是如何处理的。本研究试图通过调查什么样的信息存储在两个位置（“在哪里”是线索）和属性（“什么”是线索的属性）的视觉线索的处理的特点。在11个实验中，受试者进行了几次报告目标字母的试验，然后回答了一个关于提示的意外问题（例如，提示的位置、颜色或标识）。这个令人惊讶的问题表明，即使线索从未指出目标位置，并且被明确告知忽略它，参与者也可以报告线索的位置，而且在编码下一个目标时，这个位置信息的记忆痕迹仍然存在。与位置相反，提示的属性（例如，颜色）的报告很差，甚至对于受试者执行任务所使用的属性。这些结果揭示了新的线索效应的机制，也表明，视觉系统可能会创建空的目标文件，以响应视觉线索。(C)2014爱思唯尔有限公司版权所有。
Although it has been well known that visual cues affect the perception of subsequent visual stimuli, relatively little is known about how the cues themselves are processed. The present study attempted to characterize the processing of a visual cue by investigating what information about the cue is stored in terms of both location ("where" is the cue) and attributes ("what" are the attributes of the cue). In 11 experiments subjects performed several trials of reporting a target letter and then answered an unexpected question about the cue (e.g., the location, color, or identity of the cue). This surprise question revealed that participants could report the location of the cue even when the cue never indicated the target location and they were explicitly told to ignore it. Furthermore, the memory trace of this location information endured during encoding of the subsequent target. In contrast to location, attributes of the cue (e.g., color) were poorly reported, even for attributes that were used by subjects to perform the task. These results shed new light on the mechanisms underlying cueing effects and suggest also that the visual system may create empty object files in response to visual cues. (C) 2014 Elsevier Ltd.
