Change Blindness Image Database

This archive includes the full 100-images used in the development of the Change Detection Task. Images with and without the target are provided, as well as a separate folder where the target has been highlighted.Two versions of the task are also provided, a 40-image version and a 20-image version. Each version is further divided into Set A and Set B of the task. This allows for repeated measures designs using the task. Within each folder of both versions is a CSV file containing data pertaining to performance on each image for that version of the task.A CSV file is also provided that details the changing feature, the X and Y pixel details of the target, and total area of the image the target covers.Lastly, eight practice images and four 'easy' images are provided. These easy images contain a larger target that is easier to detect in order to protect against task difficulty reducing task motivation.A jamovi and CSV datafile is also provided for a study that investigated change detection performance and executive functioning.本归档文件包含用于开发变化检测任务（Change Detection Task）的全部100张图像。同时提供了包含目标与不含目标的原始图像，另有独立文件夹存放已高亮标注目标的图像。本任务设有两个变体版本：40图像版与20图像版，每个版本均进一步划分为任务集A与任务集B，可支持基于该任务的重复测量实验设计。两个版本的每个子文件夹中均附带一个CSV文件，存储对应版本任务中每张图像的被试表现相关数据。另有一份CSV文件，详细记录了目标的变化特征、目标的X与Y像素坐标，以及目标在整张图像中所占的总像素面积。此外还配备8张练习图像与4张“简易”图像，简易图像的目标尺寸更大，更易于检测，旨在避免因任务难度过高降低被试的任务参与意愿。另有配套的jamovi格式与CSV格式数据文件，对应一项探究变化检测表现与执行功能关联的研究。
