确定瞳孔完全适应黑暗时的直径，以及研究将一只或两只眼睛暴露在给定亮度下的效果。在研究的第一部分中，在三个S的整个强度范围内拍摄了瞬时照片。每个S的曲线形状大致相同，尽管在实际瞳孔直径上发现了个体差异。一只眼睛闭上，瞳孔的直径明显增大。强度增加到100毫安以上后，直径停止减小。在研究的第二部分，6名受试者睁着双眼暴露在6个合适的亮度水平下。所得曲线显示瞳孔最大直径的个体差异较大，范围在7-8.5 mm之间。平均瞳孔达到最小直径的时间比达到最大直径的时间要短。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Ascertains the diameter of the pupil when fully adapted to the darkness, as well as investigates the effect of exposing one or both eyes to a given brightness. In the first part of the study, instantaneous photographs were taken over the entire range of intensities for three Ss. The shape of the curves was approximately the same for each S, though individual differences were found in actual pupillary diameters. The closing of one eye markedly increased the diameter of the pupil. The diameter stopped decreasing after the intensity increased above 100 milliamberts. In the second part of the study, six Ss were exposed to six suitable brightness levels with both eyes open. The curves obtained showed large individual variations in the maximum diameter of pupils, which ranged from 7-8.5 mm. The average pupil took less time to reach its minimum than its maximum diameter.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
