Feedback-related negativity (FRN) reflects how the brain processes losses and response correctness. This study found FRN is influenced by both monetary outcomes and the accuracy of a participant's guess in a gambling task.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Decision Making
Background:
- The feedback-related negativity (FRN) is an event-related potential sensitive to negative feedback, particularly monetary loss.
- Understanding the precise factors modulating FRN amplitude is crucial for cognitive neuroscience and understanding decision-making processes.
Purpose of the Study:
- To investigate the interplay between feedback valence (gain/loss) and response correctness in modulating the feedback-related negativity (FRN).
- To determine if FRN amplitude is influenced by the utilitarian value of feedback in a gambling context.
Main Methods:
- Participants engaged in a gambling task involving card choices with unpredictable monetary gains or losses.
- Feedback indicated monetary outcome and response correctness.
- Electroencephalography (EEG) was used to measure event-related potentials, specifically focusing on FRN amplitudes.
Main Results:
- Larger FRN amplitudes were observed for losses versus gains when participants guessed correctly.
- Greater FRN amplitudes occurred for incorrect versus correct choices when participants gained money.
- FRN effects were diminished following incorrect choices that resulted in losses.
Conclusions:
- The feedback-related negativity (FRN) appears to reflect an interaction between the correctness of a guess and the utilitarian value of the feedback received.
- FRN is not solely driven by monetary loss but is modulated by the cognitive evaluation of the feedback's significance.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
