In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy.

After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door.
