Abstract

In a visual event-related potential experiment, both N100 augmenting/reducing data and oddball paradigm P300 data were collected from the same subjects. A significant correlation was obtained between augmenting/reducing and the degree to which stimulus probability affected P300 amplitude. Subjects who augment/reduce in response to increased stimulus brightness in the sensory domain also appear to augment/reduce in response to low probability in the cognitive domain.

摘要

在一项视觉事件相关电位实验中，从同一受试者身上收集了N100增强/减弱数据和Oddball范式P300数据。增强/减弱与刺激概率影响P300波幅的程度之间存在显著相关性。在感觉领域对刺激亮度增加做出增强/减弱反应的受试者，在认知领域对低概率刺激似乎也会做出增强/减弱反应。
