Pride and Status: Unpacking Two Divergent Pathways to Cooperation
… attainment, prestige and dominance. The main behavioral experiment in this study involved creating a status hierarchy and using the Ultimatum Game (UG) to test novel hypotheses. It was found that participants were more willing to offer a fair split of money to opponents who displayed a …

On The Origin of Sensory Errors
… seem that a complicated electrophysiological experiment would need to be performed to test this hypothesis. However, using a strong theoretical framework, I demonstrate that it is possible to determine statistical characteristics of the physiological mechanism responsible for perceptual errors …

Into the Wild: Deploying Brain and Physiological Sensing in Natural Environments to Enhance Wake and Sleep Cognitive Behavioral Studies
This thesis presents two experimental platforms for performing cognitive behavioral studies in natural settings: one for wake time and one for sleep. The equipment utilized today in behavioral and sleep labs is not very accessible, comfortable, portable, or simple to operate. The systems documented …

Theoretical and experimental examinations of target-based decision making
… questions—and others—using both theoretical and experimental means. A value gap model is developed that facilitates simulation based insights to target optimality. The effect of a target is characterized in terms of a value gap that is defined as the difference in value between what was selected …
