Looking is a fundamental exploratory behavior by which infants acquire knowledge about the world. In theories of infant habituation, however, looking as an exploratory behavior has been deemphasized relative to the reliable nature with which looking indexes active cognitive processing. We present a new theory that connects looking to the dynamics of memory formation and formally implement this theory in a Dynamic Neural Field model that learns autonomously as it actively looks and looks away from a stimulus. We situate this model in a habituation task and illustrate the mechanisms by which looking, encoding, working memory formation, and long-term memory formation give rise to habituation across multiple stimulus and task contexts. We also illustrate how the act of looking and the temporal dynamics of learning affect each other. Finally, we test a new hypothesis about the sources of developmental differences in looking.
看是婴儿获取关于世界的知识的一种基本探索行为。然而,在婴儿习惯化理论中,与可靠地反映主动认知加工的性质相比,看作为一种探索行为被淡化了。我们提出了一个新的理论,将看与记忆形成的动态联系起来,并在一个动态神经场模型中正式实现了这一理论,该模型在积极观察和观察刺激时会自主学习。我们将这个模型置于习惯化任务中,并说明了看、编码、工作记忆形成和长期记忆形成是如何在多个刺激和任务背景下导致习惯化的。我们还说明了看的行为和学习的时间动态是如何相互影响的。最后,我们检验了关于看的发展差异来源的一个新假设。
