We use visual working memory (VWM) to maintain the visual features of objects in our world. Although the capacity of VWM is limited, it is unlikely that this limit will pose a problem in daily life, as visual information can be supplemented with input from our external visual world by using eye movements. In the current study, we influenced the trade-off between eye movements and VWM utilization by introducing a cost to a saccade. Higher costs were created by adding a delay in stimulus availability to a copying task. We show that increased saccade cost results in less saccades towards the model and an increased dwell time on the model. These results suggest a shift from making eye movements towards taxing internal VWM. Our findings reveal that the trade-off between executing eye-movements and building an internal representation of our world is based on an adaptive mechanism, governed by cost-efficiency.

外部存储器的证据:内部和外部视觉存储器之间的权衡。
我们使用视觉工作记忆(VWM)来维护我们世界中对象的视觉特征。尽管VWM的容量受到限制,但此限制不太可能在日常生活中造成问题,因为可以通过使用眼球运动补充视觉外部信息来补充视觉信息。在当前的研究中,我们通过为扫视运动增加了成本,从而影响了眼球运动和VWM使用之间的权衡。通过将刺激可用性的延迟添加到复制任务中来创建更高的成本。我们显示,扫视运动成本的增加导致对模型的扫视运动减少,并且模型的停留时间增加。这些结果表明,人们已经从目光转向向内部大众汽车征税。
