In our recent paper, we are investigating how information gathering changes over childhood and adolescence. We found that children gathered substantially more information before making a decision, but only if it came at no extra costs for sampling information. Using further computational modelling we showed that this effect was driven by a later emergence of subjective sampling costs for gathering information. These findings help us to understand how such cognitive functions develop, and how different information gathering impairments arise in adolescence-related psychiatric disorders.
