Data and stimuli of the experiment: Pictorial Space Crafts: The Ames' Glass

There are various ways to evoke stereopsis without binocular disparities. Closing one eye, or looking through a synopter are well-known methods. Ames (1925) listed nine ways of generating this so-called `plastic effect', one of which involves a cylindrically curved lens placed in front of one eye. We investigated qualitative perceptual effects of this particular way of viewing artworks. A total of 38 participants viewed three digitally reproduced paintings. <br>Initially, they were asked to spontaneously report the perceptual effect of the lens. While being naive to the purpose of the experiment, 66% of the participants reported increased depth experience. In addition, participants reported increased contrast, color vibrance, and material expression (e.g. increased shininess). <br>During a second part of the experiment, we asked to report on seven qualities, Depth, Color, 3D shape, Realism, Detail, Light and Material. All qualities increased significantly except Detail, which seemed to show idiosyncratic results: the majority of the observers experienced a decrease of detail, while a minority reported, surprisingly, an increase of detail. <br>The data set contains the raw responses and also the data we used to perform analysis with Claude.ai including prompts.

无需双眼视差即可诱发立体视觉（stereopsis）的方式多种多样。单眼视物或通过立体视镜（synopter）观察均为广为人知的方法。埃姆斯（Ames, 1925）曾列举出九种可产生这类被称为“塑性效应（plastic effect）”的方式，其中一种便是在单眼前放置圆柱曲面透镜。本研究针对该特定观赏艺术品的方式所带来的知觉质性效应展开了探究。总计38名受试者观看了三幅数字化复刻的画作。
实验初始阶段，受试者被要求自发报告该透镜带来的知觉效应。由于对实验目的不知情，66%的受试者报告称自身的深度感知体验有所增强。此外，受试者还提及对比度提升、色彩鲜亮程度改善以及材质表现力增强（例如光泽度提升）。
实验第二阶段，我们要求受试者对七个评定维度进行评分报告，分别为：深度、色彩、三维形状、真实感、细节、光照以及材质。除细节维度外，其余所有维度的评分均出现显著提升；细节维度则呈现出特异性结果：多数受试者报告细节感知有所下降，而令人意外的是，少数受试者则称细节感知有所提升。
本数据集包含原始应答数据，以及我们用于借助Claude.ai开展分析时所使用的包含提示词在内的相关数据。
