A variety of psychological and physical phenomena elicit variations in the diameter of pupil of the eye. Changes in pupil size are mediated by the relative activation of the sphincter pupillae muscle (decrease pupil diameter) and the dilator pupillae muscle (increase pupil diameter), innervated by the parasympathetic and sympathetic branches, respectively, of the autonomic nervous system. The current guidelines are intended to inform and guide psychophysiological research involving pupil measurement by (1) summarizing important aspects concerning the physiology of the pupil, (2) providing methodological and data-analytic guidelines and recommendations, and (3) briefly reviewing psychological phenomena that modulate pupillary reactivity. Because of the increased ease and tractability of pupil measurement, the goal of these guidelines is to promote accurate recording, analysis, and reporting of pupillary data in psychophysiological research.
各种心理和生理现象都会引起瞳孔直径的变化。瞳孔大小的变化是由瞳孔括约肌（缩小瞳孔直径）和瞳孔扩张肌（扩大瞳孔直径）的相对激活介导的，它们分别由自主神经系统的副交感和交感分支支配。本指南旨在通过以下方式为涉及瞳孔测量的心理生理学研究提供信息和指导：（1）总结有关瞳孔生理学的重要方面；（2）提供方法学和数据分析指南和建议；（3）简要回顾调节瞳孔反应性的心理现象。由于瞳孔测量的简便性和可操作性的提高，这些指南的目标是促进心理生理学研究中瞳孔数据的准确记录、分析和报告。
