The Sustained Influence of an Error on Future Decision-Making.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Decision Science

Background:

• Post-error slowing (PES) is a common phenomenon after errors in decision-making tasks.
• Previous research on PES's role in performance accuracy remains inconclusive.

Purpose of the Study:

• To investigate the underlying cognitive mechanisms of PES using drift diffusion modeling.
• To determine if PES contributes to improved performance accuracy in a visual search task.

Main Methods:

• Utilized drift diffusion modeling on a large dataset (>5,800 participants) from a visual search experiment.
• Analyzed reaction times and accuracy, focusing on post-error trial dynamics.
• Incorporated emotional face stimuli to examine contextual influences.

Main Results:

• Post-error trials showed adaptive increases in response threshold, sustained over trials.
• Evidence accumulation rate initially decreased (indicating distraction) then increased post-error.
• Higher decision thresholds and evidence accumulation post-error correlated with improved subsequent accuracy.
• Emotional context (angry faces) modulated the evidence accumulation rate post-error.

Conclusions:

• Error-related adaptations are multi-component and dynamic, extending over multiple trials.
• PES involves both adaptive (threshold) and non-adaptive (attention/distraction) decision processes.
• Decision threshold and evidence accumulation are key parameters for post-error adaptation and performance improvement.
