Information-Seeking Decision Strategies Mitigate Risk in Dynamic, Uncertain Environments

Area of Science:

• Cognitive Science
• Behavioral Economics
• Computational Neuroscience

Background:

• Individuals need adaptive decision strategies for uncertain environments.
• Existing models often focus on optimizing rewards or gathering diverse information.
• Limited research compares these strategies in dynamic, real-world settings.

Purpose of the Study:

• Compare normative reward-seeking and information-seeking strategies.
• Evaluate their performance in a dynamic foraging task.
• Understand the trade-offs between reward optimization and information gathering.

Main Methods:

• Simulated a dynamic foraging task with changing environmental uncertainty.
• Implemented and compared normative reward-seeking and information-seeking decision strategies.
• Analyzed behavioral transitions and performance outcomes.

Main Results:

• Both strategies exhibited similar shifts between exploration and exploitation.
• Reward-seeking strategies yielded slightly higher average rewards.
• Information-seeking strategies produced more consistent and predictable outcomes.
• Information-seeking mitigated risk with minimal loss in average reward.

Conclusions:

• Information-seeking behaviors are adaptive for risk mitigation in dynamic environments.
• There are subtle but meaningful performance differences between reward- and information-seeking strategies.
• Balancing information gathering and commitment is crucial for survival in uncertainty.
