In a previous report it was shown that covertly attending visual stimuli produce small convergence of the eyes, and that visual stimuli can give rise to different modulations of the angle of eye vergence, depending on their power to capture attention. Working memory is highly dependent on attention. Therefore, in this study we assessed vergence responses in a memory task. Participants scanned a set of 8 or 12 images for 10 s, and thereafter were presented with a series of single images. One half were repeat images - that is, they belonged to the initial set - and the other half were novel images. Participants were asked to indicate whether or not the images were included in the initial image set. We observed that eyes converge during scanning the set of images and during the presentation of the single images. The convergence was stronger for remembered images compared with the vergence for nonremembered images. Modulation in pupil size did not correspond to behavioural responses. The correspondence between vergence and coding/retrieval processes of memory strengthen the idea of a role for vergence in attention processing of visual information.
在之前的一份报告中表明，暗中关注视觉刺激会使眼睛产生微小的辐辏，并且视觉刺激会根据其吸引注意力的能力引起不同程度的眼辐辏角度调制。工作记忆高度依赖于注意力。因此，在本研究中，我们评估了记忆任务中的辐辏反应。参与者对一组8张或12张图像扫描10秒，之后会呈现一系列单张图像。其中一半是重复图像——即它们属于初始图像集——另一半是新图像。要求参与者指出这些图像是否包含在初始图像集中。我们观察到，在扫描图像集期间以及呈现单张图像期间眼睛会发生辐辏。与未记住图像的辐辏相比，记住图像的辐辏更强。瞳孔大小的调制与行为反应不对应。辐辏与记忆的编码/检索过程之间的对应关系强化了辐辏在视觉信息注意力处理中起作用的观点。
