项目摘要
The purpose of this study is to evaluate the influence of ``undetectable motions'', the motion information under the perception threshold, on cognitive functions by statistical analyses of the property of fixation eye movements. Subjects performed rapid serial visual presentation (RSVP) tasks with undetectable or ambiguous motions in the background while maintaining their fixation. We evaluated the influence of these motions on top-down attention mechanism by analyzing fixation eye movements. The results suggest that microsaccade rates were correlated with subliminal motion information, and fluctuations of drift eye movements were modulated by low-contrast motions in the peripheral vision.
这项研究的目的是评估``不可检测的动议''的影响,即感知阈值下的运动信息,通过对固定眼运动特性的统计分析对认知功能的影响。受试者执行了快速的串行视觉呈现(RSVP)任务,但在保持固定性的同时,在背景中具有不可检测的或模棱两可的动作。我们通过分析固定眼运动来评估这些运动对自上而下的注意机制的影响。结果表明,微扫描速率与潜意识的运动信息相关,并且在外围视觉中低对比度运动调节漂移眼动的波动。
