We discuss hypotheses that link the measurements we can make with infants to inferences about their developing neural mechanisms. First, we examine evidence from the sensitivity to visual stimulus properties seen in infants' responses, using both electrophysiological measures (transient and steady-state recordings of visual evoked potentials/visual event-related potentials) and behavioral measures and compare this with the sensitivity of brain processes, known from data on mammalian neurophysiology and human neuroimaging. The evidence for multiple behavioral systems with different patterns of visual sensitivity is discussed. Second, we consider the analogies which can be made between infants' behavior and that of adults with identified brain damage, and extend these links to hypothesize about the brain basis of visual deficits in infants and children with developmental disorders. Last, we consider how these lines of data might allow us to form "inverse linking hypotheses" about infants' visual experience.
我们讨论了一些假设，这些假设将我们对婴儿进行的测量与对他们正在发育的神经机制的推断联系起来。首先，我们使用电生理测量方法（视觉诱发电位/视觉事件相关电位的瞬态和稳态记录）和行为测量方法，研究婴儿反应中对视觉刺激特性的敏感性证据，并将其与从哺乳动物神经生理学和人类神经影像学数据中已知的大脑过程的敏感性进行比较。我们还讨论了具有不同视觉敏感性模式的多个行为系统的证据。其次，我们考虑婴儿行为与已确定脑损伤的成年人行为之间的类比，并扩展这些联系，以推测发育障碍婴儿和儿童视觉缺陷的脑基础。最后，我们考虑这些数据线索如何使我们能够形成关于婴儿视觉体验的“反向联系假设”。
