Addiction beyond pharmacological effects: the role of environment complexity and bounded rationality

This paper introduces a reinforcement learning model to show how environmental complexity and bounded rationality contribute to non-pharmacological addiction by causing cognitive overload and suboptimal decision-making.

A Multilevel Computational Characterization of Endophenotypes in Addiction

This paper simulates endophenotypic variations in addiction using neural and reinforcement learning models, finding that imbalances between cortico-striatal systems affect addiction outcomes and treatment responses.
