Identifying the Neural Correlates of Mental Simulation in Multi-Step Planning

Planning is the ability to think ahead by considering possible future actions and their consequences. This research study aims to understand how the brain supports multi-step planning by testing whether people simulate promising future move sequences while deciding what to do next. Healthy adult volunteers will learn and play a strategy game called "Four-in-a-Row" (similar to Connect Four). Participants will complete two sessions on successive days: an online behavioral training/playing session and an in-person brain-recording session at New York University. During the brain-recording session, participants will view mid-game board positions and choose the best move while the study team records brain activity (using magnetoencephalography [MEG] or functional MRI [fMRI]) and eye movements. Data from the game and eye tracking will also be used to fit computational models of planning that help interpret the neural measurements.
