OBJECTIVE We review the sampling models described in John Senders's doctoral thesis on "visual sampling processes" via a ready and accessible exposition. BACKGROUND John Senders left a significant imprint on human factors/ergonomics (HF/E). Here, we focus on one preeminent aspect of his career, namely visual attention. METHODS We present, clarify, and expand the models in his thesis through computer simulation and associated visual illustrations. RESULTS One of the key findings of Senders's work on visual sampling concerns the linear relationship between signal bandwidth and visual sampling rate. The models that are used to describe this relationship are the periodic sampling model (PSM), the random constrained sampling model (RCM), and the conditional sampling model (CSM). A recent replication study that used results from modern eye-tracking equipment showed that Senders's original findings are manifestly replicable. CONCLUSIONS Senders's insights and findings withstand the test of time and his models continue to be both relevant and useful to the present and promise continued impact in the future. APPLICATION The present paper is directed to stimulate a broad spectrum of researchers and practitioners in HF/E and beyond to use these important and insightful models.

论视觉采样行为的发送者模型

目标 我们通过现成且易于理解的阐述回顾了 John Senders 关于“视觉采样过程”的博士论文中描述的采样模型。背景 John Senders 在人为因素/人体工程学 (HF/E) 领域留下了重要的印记。在这里，我们重点关注他职业生涯中的一个突出方面，即视觉注意力。方法我们通过计算机模拟和相关的视觉插图来呈现、阐明和扩展他论文中的模型。结果 Senders 在视觉采样方面的工作的主要发现之一涉及信号带宽和视觉采样率之间的线性关系。用于描述这种关系的模型是周期抽样模型（PSM）、随机约束抽样模型（RCM）和条件抽样模型（CSM）。最近的一项使用现代眼球追踪设备结果的复制研究表明，发件人的原始发现显然是可以复制的。结论 发件人的见解和发现经受住了时间的考验，他的模型对于当前仍然具有相关性和实用性，并有望在未来产生持续的影响。应用本文旨在激励 HF/E 及其他领域的广泛研究人员和从业者使用这些重要且富有洞察力的模型。
