Computations and Connectivity Underlying Aversive Counterfactuals

Area of Science:

• Cognitive Neuroscience
• Decision Making
• Neuroimaging

Background:

• Mental simulation of counterfactuals is key to human cognition, creativity, and planning.
• The "would you rather" game exemplifies choices between negative counterfactuals.

Purpose of the Study:

• To investigate behavioral and neural correlates of making choices about aversive counterfactual scenarios.
• To examine the influence of framing (approach vs. avoidance) on decision-making and brain activity.

Main Methods:

• Participants made "would you rather" choices framed as approaching or avoiding negative counterfactuals.
• Behavioral data (reaction times) and brain imaging (fMRI) were collected.
• Bayesian graph connectivity analysis and computational modeling were employed.

Main Results:

• Participants responded significantly slower to approach frames than avoidance frames, indicating framing susceptibility.
• Brain imaging revealed activation patterns consistent with aversive stimulus processing networks, with differing connectivity for approach vs. avoidance choices.
• Computational modeling showed approach frames led to longer nondecision times and altered evidence accumulation compared to avoidance frames.

Conclusions:

• Decisions about aversive counterfactuals differentially recruit limbic circuit connectivity based on choice framing.
• Cognitive evaluations of counterfactuals involve flexible representations influenced by framing.
• Findings have implications for understanding prospective decision-making.
