摘要

长时间保持注意力集中是一项挑战,尤其是当目标刺激在时间序列中缺失时。先前的研究表明,填补时间空白的时间注意线索可以提高持续注意:在一项持续视觉注意任务中,要求手指敲击与由短暂闪烁的圆盘和空白期交错组成的时间规律序列同步,当作为时间注意线索的连续固定点叠加在圆盘刺激上时,任务表现会有所提高。为了验证这样一个假设,即通过空间重叠将时间注意线索与目标时间序列结合在一起对增强持续注意至关重要,本研究进行了一系列共三个实验,以解构线索与序列刺激之间的绑定联系。在实验 1 中,提示被放置在闪盘的上方或下方。在实验 2 中,提示位于两个垂直排列的闪光盘之间。在实验 3 中,提示位于一个闪光环中。在这三个实验中,都没有发现持续注意力改善的明显效果。当时间线索叠加在序列刺激上时,实验 4 进一步复制了这些无效结果以及之前观察到的持续注意力改善效果。我们的研究结果表明,当序列刺激缺失时,在时空空白期间通过空间重叠进行绑定对于增强持续注意力至关重要,这应该有利于提高需要长时间保持注意力的更广泛任务的成绩。

Sustaining attention in visuomotor timing is associated with location-based binding

Maintaining focus of attention over prolonged periods can be challenging, especially when the target stimulus is absent from the temporal sequence. Prior research has shown that a temporal attentional cue filling in the temporal blank can improve sustained attention: in a sustained visual attention task requiring synchronizing finger tapping with a temporally regular sequence composed of brief flash disks interleaved with blank periods, task performance was improved when a continuous fixation point that served as a temporal attentional cue was presented superimposed on the disk stimulus. To test the hypothesis that binding the temporal attentional cue with the target temporal sequence by spatial overlapping is crucial for enhancing sustained attention, the present study conducted a series of three experiments that deconstructed the bound connection between the cue and the sequence stimulus. In Experiment 1, the cue was placed above or below a flash disk. In Experiment 2, the cue was between two vertically arranged flash disks. In Experiment 3, the cue was in a flash ring. No significant effect of sustained attention improvement was found in any of the three experiments. Experiment 4 further replicated these null results and the previously observed effect of sustained attention improvement when the temporal cue was superimposed on the sequence stimulus. Our finding demonstrates that binding by spatial overlapping during the temporal blank when the sequence stimulus is absent is critical for enhancing sustained attention, which should be beneficial for improving performance across a broader range of tasks that require prolonged maintenance of attention.

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
