Reinforcement Learning and Decision Making: Computational and Neural Mechanisms

Course 2016-2017

Entry requirements

Only open to MSc Psychology (research) students.

Description

Reinforcement learning is the adaptive process by which we learn to predict the consequences of our behavior through interactions with our environment. Over the last few decades, this has been intensively studied in a range of fields including psychology, artificial intelligence, animal and human neuroscience and economics. A related but largely separate literature is concerned with how we make optimal decisions based on noisy sensory information. Computational models of the putative underlying mechanisms of learning and decision making play a central role in both of these research fields. This course is intended to provide an overview of the computational and neural mechanisms of reinforcement learning and (value-based and perceptual) decision making, and to gain insight in the use of computational models to account for experimental data. Topics include classical and instrumental conditioning, Markov decision processes, the exploitation-exploration tradeoff, and sequential sampling models of perceptual decision-making.

The course meetings will be based on empirical papers that have made a significant contribution to the field and on papers that review a substantial body of research. Each student will write a short essay about a current issue in the reinforcement learning and/or decision making literature, and will initiate and lead a group discussion about this. In addition, students will gain hands-on experience with fitting computational models to experimental data, apply a model-based analysis to a data set, and present their results on a scientific poster.

Course objectives

Upon completion of the course, students will:

  • be introduced to the fields of reinforcement learning and decision-making, and obtain an overview of their key paradigms, models, findings and challenges;
  • gain insight and practical experience in the use of computational models to explain and interpret experimental data; and
  • obtain a basic understanding in how to translate abstract theoretical concepts in the field to concrete experiments, and learn to account for experimental findings through modelling considerations.
