安德烈斯·桑德斯的论文研究了功能视野中的选择机制，自那以后，他的大部分工作都与视觉信息处理的基础阶段有关，特别是在进行眼跳时。我们认为，功能视野中的定向研究是及时的，因为它处理了隐蔽的注意力转移、眼球运动和头部运动与其潜在神经学的关系。在我们的论文中，我们开发了一种方法来研究从婴儿到成年人的所有年龄段的序列学习。我们的研究重点是学习如何影响预期的眼动。我们考察了4个月、10个月和18个月大的婴儿和本科生对明确和上下文相关序列的学习情况。我们在4个月时发现了明确的学习顺序，但只有18个月大的婴儿和成年人才能学习到上下文相关的联系。我们假设，4个月大婴儿对明确序列的学习反映了与成人内隐学习相关的基底节-顶叶回路的成熟，而上下文相关序列的学习需要发展支持更一般注意能力的额叶结构，(C)2001 Elsevier Science B.V.保留所有权利。
Andries Sanders' dissertation examined selective mechanisms in the functional visual field, and much of his work since has been concerned with the stages that underlie visual information processing particularly while making saccades. We argue that the study of orienting in the functional visual field is timely because it deals with the relation of covert attention shifts, eye movements and head movements to their underlying neurology. In our paper we develop a method to study learning of sequences at all ages from infants to adults. Our studies focus on how learning influences anticipatory eye movements. We examined the learning of unambiguous and context dependent sequences by 4-, 10-, and 18-month-old infants and undergraduates. We found clear learning of unambiguous sequences at 4 months, but learning of context dependent associations was found only in 18-month-olds and in adults. We hypothesize that the learning of unambiguous sequences by 4-month-olds reflects maturation of a basal ganglia-parietal circuit related to adult implicit learning, while the learning of context dependent sequences requires development of frontal structures underlying more general attentional abilities, (C) 2001 Elsevier Science B.V.
