Development of decision making based on internal and external information: A hierarchical Bayesian approach

In decision making, people may rely on their own information as well as on information from external sources, such as family members, peers, or experts. The current study investigated how these types of information are used by comparing four decision strategies: 1) an internal strategy that relies s...
