Prior information about distractor facilitates selective attention to task-relevant items and helps the optimization of oculomotor planning. In the present study, we capitalized on gaze-position decoding to examine the dynamics of attentional deployment in a feature-based attentional task that involved two groups of dots (target/distractor dots) moving toward different directions. In Experiment 1, participants were provided with target cues indicating the moving direction of target dots. The results showed that participants were biased toward the cued direction and tracked the target dots throughout the task period. In Experiment 2 and Experiment 3, participants were provided with cues that informed the moving direction of distractor dots. When the distractor cue varied on a trial-by-trial basis (Experiment 2), participants continuously monitored the distractor’s direction. However, when the to-be-ignored distractor direction remained constant (Experiment 3), participants would strategically bias their attention to the distractor’s direction before the cue onset to reduce the cost of redeployment of attention between trials and reactively suppress further attraction evoked by distractors during the stimulus-on stage. This functional dissociation reflected the distinct influence that expectation produced on ocular control. Taken together, these results suggest that monitoring the distractor’s feature is a prerequisite for feature-based attentional inhibition, and this process is facilitated by the predictability of the distractor’s feature.

先验知识和期望下基于特征的干扰物抑制的注视动力学

有关牵张器的先前信息有助于选择性关注与任务相关的项目,并有助于优化动眼计划。在本研究中,我们利用注视位置解码技术来研究基于特征的注意力任务中注意力部署的动力学,该任务涉及两组朝不同方向移动的点(目标/干扰点)。在实验1中,向参与者提供了指示目标点移动方向的目标提示。结果表明,参与者偏向提示方向,并在整个任务期间跟踪目标点。在实验2和实验3中,为参与者提供了指示干扰点移动方向的提示。当干扰项的提示在逐项试验的基础上有所不同时(实验2),参与者不断地监视着牵引器的方向。但是,当要忽略的撑开器方向保持不变时(实验3),参与者会在提示发生之前从战略上将注意力转移到撑开器的方向上,以减少试验之间注意力的重新部署成本,并以反应方式抑制撑开器引起的进一步吸引力在刺激阶段。这种功能分离反映出预期对眼控产生的独特影响。综上所述,这些结果表明,监视撑开器的特征是基于特征的注意力抑制的前提,并且该过程可通过撑开器的特征的可预测性来促进。参与者会在提示发生之前从战略上将注意力转移到干扰物的方向上,以减少试验之间重新部署注意力的成本,并在刺激阶段中反应性地抑制干扰物引起的进一步吸引力。这种功能分离反映出预期对眼控产生的独特影响。综上所述,这些结果表明,监视撑开器的特征是基于特征的注意力抑制的前提,并且该过程可通过撑开器的特征的可预测性来促进。参与者会在提示发生之前从战略上将注意力转移到干扰物的方向上,以减少试验之间重新部署注意力的成本,并在刺激阶段中反应性地抑制干扰物引起的进一步吸引力。这种功能分离反映出预期对眼控产生的独特影响。综上所述,这些结果表明,监视撑开器的特征是基于特征的注意力抑制的前提,并且该过程可通过撑开器的特征的可预测性来促进。这种功能分离反映出预期对眼控产生的独特影响。综上所述,这些结果表明,监视撑开器的特征是基于特征的注意力抑制的前提,并且该过程可通过撑开器的特征的可预测性来促进。这种功能分离反映出预期对眼控产生的独特影响。综上所述,这些结果表明,监视撑开器的特征是基于特征的注意力抑制的前提,并且该过程可通过撑开器的特征的可预测性来促进。
