Abstract

Behavioral and electroencephalography (EEG) data were analyzed from 30 participants performing a demanding, attention-capturing task in which they had to detect an occasional decrement of luminance of small discs. Crucially, numerous white segments in the background were presented either in random orientations or configuring a contour shape of a square or a diamond. The participants\' awareness of these background configurations was tested with a questionnaire after the first and second sessions. Based on the questionnaire responses, participants were divided into \"aware\" and \"unaware\" groups. These data may be of interest to researchers who wish to understand attentional effects on Gestalt integration processes, as well as luminance discrimination.

摘要

对30名参与者的行为和脑电图（EEG）数据进行了分析，注意捕捉任务，他们必须检测到小光盘亮度的偶尔下降。至关重要的是，背景中的许多白色片段以随机取向或配置正方形或菱形的轮廓形状呈现。在第一次和第二次会议之后，参与者对这些背景配置的意识进行了问卷调查。根据问卷的答复，参与者被分为“知道”和“不知道”组。这些数据可能对希望了解注意力对格式塔整合过程的影响的研究人员感兴趣，以及亮度辨别。
