20 students from an undergraduate class participated in an experiment designed to study the effects of laterality and visual angle on time judgments. Using a standard two-field tachistoscope , subjects were exposed to two experimental conditions, (1) stimulus cards with a single red or blue dot in the center and several dots clustered on both sides near the center and equidistant from it (visual angle of .6 degrees) and (2) stimulus cards with a single red or blue dot in the center and several dots clustered on both sides away from the center on the edge of the card (visual angle of 2.6 degrees). Five cards containing a single red or blue dot were used to control for response bias. The subjects were asked to indicate whether they saw dots in the left, right, or both fields, and whether they perceived a time duration between fields. No difference in time duration existed, however, as all cards were exposed to both fields for equal durations. The predictions that the judged duration of dot patterns would be more accurate favoring the left visual-field and more accurate where the distance between the point of fixation and stimulus was larger were supported.
一个本科班级的20名学生参与了一项旨在研究偏侧性和视角对时间判断影响的实验。使用标准的双视野速示器，让受试者接受两种实验条件：（1）刺激卡片，中心有一个红色或蓝色的点，两侧靠近中心且与中心等距处有几个点聚集在一起（视角为0.6度）；（2）刺激卡片，中心有一个红色或蓝色的点，两侧远离中心且在卡片边缘处有几个点聚集在一起（视角为2.6度）。使用五张包含单个红色或蓝色点的卡片来控制反应偏差。受试者被要求指出他们是在左视野、右视野还是两个视野中看到了点，以及他们是否感知到了不同视野之间的持续时间。然而，由于所有卡片在两个视野中暴露的持续时间相同，所以在持续时间上没有差异。关于点图案的判断持续时间在左视野更准确以及注视点与刺激之间距离越大越准确的预测得到了支持。
