The Object Data Bank: A Collaborative Project Proposal to Provide a Standardized Realistic Stimulus Set of Common Objects for Experimental Psychology

TARR这个对象数据库是实验心理学家之间的一个合作项目，旨在开发一套标准化的刺激材料，描绘熟悉的常见对象。该项目的最终目标是向研究界提供一套300-500个照片级真实照明和阴影对象。每个物体将使用三维计算机辅助设计（CAD）建模技术开发，并将使用最先进的光线追踪技术进行渲染。一个给定的对象将以几种标准格式提供给研究人员，用于生成他们自己的刺激图像，而不需要复制即使是单个对象所需的时间密集型建模。为了方便那些只需要高质量图像但不需要特定控制光照、纹理和颜色的研究人员，对象也将作为已渲染图像的集合提供，每个对象以逼真的颜色描绘，至少有12个三维视点，通过围绕垂直轴旋转30度生成。 对象集最初将基于广泛使用的对象的二维线条图集，该对象的二维线条图集由Samplegrass和Vanderwart（1980）引入并分发。这组熟悉的共同对象已被用于许多不同的实验设置，并提供了方便的刺激准备和不同的研究范式之间的一些刺激标准化。我们的目标是开始通过创建每个项目的3维类似物在Samplegrass和Vanderwart集-这提供了额外的优势，提供了一些以前收集的规范数据的对象类别，以及一些基础与早期的研究进行比较。为了说明这组新对象的许多潜在应用中的一些，本文包括了来自对象感知、视觉记忆、场景识别、对象识别神经心理学、记忆神经心理学、注意力障碍临床评估等领域的几个拟议实验。如果没有常见物体的真实图像，许多拟议的研究都是不可能的。预计刺激集将有更广泛的应用，甚至比这个广泛的学科，共同的主题是，高度逼真的视觉刺激只能提高当前范式的生态相关性，以及提供新的范式，以前无法实现。 ***

TARR This object databank is intended as a collaborative project among experimental psychologists to develop a set of standardized stimulus materials depicting familiar common objects. The ultimate goal of the project is to make available to the research community a set of 300-500 photorealistically illuminated and shaded objects. Each object will be developed using 3-dimensional computer-aided design (CAD) modeling techniques and will be rendered using state-of-the-art raytracing. A given object will be available in several standard formats for researchers to use in generating their own stimulus images without the need of duplicating the time-intensive modeling required for even a single object. To facilitate researchers who need only high quality images but not specific control of lighting, textures and colors, objects will also be available as collections of already rendered images, each object depicted in realistic colors at a minimum of 12 3-dimensional viewpoints generated by 30 degree rotations around the vertical axis. The set of objects will initially be based on the widely used set of 2-dimensional line drawings of objects introduced and distributed by Snodgrass and Vanderwart (1980). This set of familiar common objects has been used in many different experimental settings and has provided ease of stimulus preparation and some stimulus standardization between differing research paradigms. The goal is to begin by creating 3-dimensional analogs of each item in the Snodgrass and Vanderwart set -- this provides the added advantage of offering some previously collected norm data about object categories, as well as some basis for comparison with earlier studies. To illustrate some of the many potential applications of this new set of objects, several proposed experiments are included from the areas of object perception , visual memory, scene recognition, neuropsychology of object recognition, neuropsychology of memory, clinical assessment of attentional disorders. Many of the proposed st udies would be impossible without realistic images of common objects. It is expected that the stimulus set will have far wider applications than even this broad range of disciplines, the common theme being that highly realistic visual stimuli can only enhance the ecological relevance of current paradigms, as well as make available new paradigms that were previously unrealizable. ***
