本研究考察了不相关效价信息加工的试对试调制。参与者（N = 126）对图片的框架颜色做出积极，中性或消极的情感内容-一个被称为情绪Stroop任务（EST）的程序。正如通常发现的那样，与中性图片相比，正面和负面图片延迟了反应。然而，这种基于效价的干扰的类型和程度取决于先前试验中不相关的图片效价。而之前暴露于负效价提示干扰的积极和消极的图片，这种干扰被删除后，中性试验。在正性图片之后，观察到来自负性图片的干扰，但未观察到来自正性图片的干扰。我们认为，这些顺序调制反映了自动自我调节的选择过程，有助于保持参加任务相关的信息和任务无关的信息，信号在环境中的重要变化之间的平衡。
This study investigated trial-to-trial modulations of the processing of irrelevant valence information. Participants (N = 126) responded to the frame color of pictures with positive, neutral, or negative affective content - a procedure known as an emotional Stroop task (EST). As is typically found, positive and negative pictures delayed responses as compared to neutral pictures. However, the type and extent of this valence-based interference depended on the irrelevant picture valence in the preceding trial. Whereas preceding exposure to negative valence prompted interference from positive and negative pictures, such interference was removed after neutral trials. Following positive pictures, interference from negative but not from positive pictures was observed. We suggest that these sequential modulations reflect automatic self-regulatory selection processes that help to keep the balance between attending to task-relevant information and task-irrelevant information that signals important changes in the environment.
