The modulation of attentional deployment on regret: an event-related potential study

Adopting a sequential risk-taking task, this study explored the modulation of attentional deployment on regret. Attentional deployment was manipulated during outcome feedback of the task by highlighting different parts to induce participants to focus on collected gains (GF context) or missed chances (MF context). The control context without attentional deployment manipulation was also set. Behaviorally, compared to the control context, participants felt less regret in the GF context but more regret in the MF context. Event-related potential results showed that the GF context elicited stronger reward positivity and late positive potential (LPP) than the control context. Furthermore, openness (NEO Five-Factor Inventory) negatively predicted the amplitude of LPP in the GF context. Source localization indicated that the superior frontal gyrus showed stronger activation in the GF context than in the control context during the time window of LPP. These results suggested that focusing on collected gains was an effective way to repress regret and that the LPP component played a key role in this process.
