研究表明，反馈相关消极性（FRN）只在预测违背显著时对期望敏感。为了进一步研究这个问题，我们让参与者猜测两个虚拟门中的哪一个隐藏了5美分。在猜测之前和之后，参与者被问到他们是否期望获胜。我们根据受试者在选择门之前和之后的预测提取了四个条件：1）“赢/赢”; 2）“输/输”; 3）“赢/输”; 4）“输/赢”。结果显示，在受试者预测他们不会赢，然后改变主意并预测他们会赢的试验中，FRN最大（即，“输/赢”条件）。结合之前的FRN结果和遗憾和决策领域的研究结果，我们认为FRN反映了一个上下文敏感的信号，整合了有关当前和过去的行为，思想和情绪的信息。
Research suggests that the feedback related negativity (FRN) is only sensitive to expectancy when the prediction violation is salient. To further examine this issue, we asked participants to guess which of two virtual doors hid 5 cents. Prior to and after making their guess, participants were asked whether or not they expected to win. We extracted four conditions based on subjects’ predictions before and after their choice of door: 1) ‘win/win’; 2) ‘lose/lose’; 3) ‘win/lose’; and 4) ‘lose/win’. Results revealed that the FRN was largest on trials in which subjects predicted they were not going to win and then changed their minds and predicted that they were going to win (i.e., the ‘lose/win’ condition). Together with previous FRN results and findings in the area of regret and decision making, we suggest that the FRN reflects a context sensitive signal that integrates information about current and past actions, thoughts, and emotions.
