Perceptual processes in human observers vary considerably across a number of domains, producing idiosyncratic biases in the appearance of ambiguous figures [1], faces [2], and a number of visual illusions [3-6]. This work has largely emphasized object and pattern recognition, which suggests that these are more likely to produce individual differences. However, the presence of substantial variation in the anatomy and physiology of the visual system [4,7,8] suggests that individual variations may be found in even more basic visual tasks. To support this idea, we demonstrate observer-specific biases in a fundamental visual task - object localization throughout the visual field. We show that localization judgments of briefly presented targets produce idiosyncratic signatures of perceptual distortions in each observer and suggest that even the most basic visual judgments, such as object location, can differ substantially between individuals.
人类观察者在许多领域的感知过程存在很大差异，导致在模棱两可的图形[1]、面孔[2]和许多视觉错觉[3-6]的外观上出现独特的偏差。这项工作主要强调了对象和模式识别，这表明这些更容易产生个体差异。然而，视觉系统的解剖结构和生理学存在很大的差异[4,7,8]，这表明即使在更基本的视觉任务中也可能存在个体差异。为了支持这一观点，我们在一项基本的视觉任务——整个视野中的物体定位中展示了观察者特定的偏差。我们表明，对短暂呈现的目标的定位判断会在每个观察者中产生感知扭曲的独特特征，并表明即使是最基本的视觉判断，例如物体位置，也可以在个体之间有很大的差异。
