Past research suggests a continuity between perception and memory, as reflected in influences of orienting of spatial attention by cues presented after a visual target offset (post-target cues) on target perception. Conducting two experiments, we tested and confirmed this claim. Our study revealed an elevated reliance on post-target cues for target detection with diminishing target visibility, leading to better performance in validly versus invalidly cued trials, indicative of contrast gain. We demonstrated this post-target cueing impact on target perception without a postcue response prompt, meaning that our results truly reflected a continuity between perception and memory rather than a task-specific impact of having to memorize the target due to a response prompt. While previous studies found an improvement in accuracy through valid compared to invalid cues using liminal targets, in Experiment 1, we further showed an influence of attention on participants' response time by the post-target cues with cues presented away from a clearly visible target. This suggests that visual interactions at the target location provided no better explanation of post-target cueing effects. Our results generalize prior research with liminal targets and confirm the view of a perception-memory continuum so that visual target processing is not shielded against visuospatial orienting of attention elicited by events following the offset of the visual target.
以往的研究表明,感知与记忆之间存在连续性,这体现在视觉目标消失后呈现的线索(目标后线索)对空间注意定向的影响会作用于目标感知。通过进行两项实验,我们对这一观点进行了测试并予以证实。我们的研究发现,随着目标可见度的降低,目标检测对目标后线索的依赖程度增加,这导致在有效线索提示与无效线索提示的试验中表现更好,这表明存在对比增益。我们证明了这种目标后线索提示对目标感知的影响,且不存在线索后反应提示,这意味着我们的结果真正反映了感知与记忆之间的连续性,而不是由于反应提示而必须记忆目标所产生的特定任务影响。虽然之前的研究发现,使用阈限目标时,有效线索提示相比无效线索提示能提高准确性,但在实验1中,我们进一步表明,目标后线索提示会影响参与者的反应时间,且线索与清晰可见的目标相距一定距离。这表明,目标位置的视觉交互并不能更好地解释目标后线索提示效应。我们的结果推广了之前关于阈限目标的研究,并证实了感知 - 记忆连续体的观点,即视觉目标处理无法免受视觉目标消失后事件引发的视觉空间注意定向的影响。
