视觉工作记忆（VWM）容量已被广泛研究，在成人中，方法的进步，使研究人员能够探测容量限制在婴儿期使用优先寻找范式。有证据表明，在6至10个月大的时候，能力迅速增加。为了理解VWM系统是如何发展的，我们必须理解用于研究VWM的注视行为与潜在的认知过程之间的关系。我们提出了一个动态的神经场模型，捕捉实时和发展过程的基础性能。三个模拟实验表明，在婴儿期看是如何与VWM过程，以及如何通过增加神经连接的性能发展变化可能会出现。这些结果提供了洞察能力的限制和VWM发展的来源更普遍。
Visual working memory (VWM) capacity has been studied extensively in adults, and methodological advances have enabled researchers to probe capacity limits in infancy using a preferential looking paradigm. Evidence suggests that capacity increases rapidly between 6 and 10 months of age. To understand how the VWM system develops, we must understand the relationship between the looking behavior used to study VWM and underlying cognitive processes. We present a dynamic neural field model that captures both real-time and developmental processes underlying performance. Three simulation experiments show how looking is linked to VWM processes during infancy and how developmental changes in performance could arise through increasing neural connectivity. These results provide insight into the sources of capacity limits and VWM development more generally.
