We examine the impact of glucose on a Bayesian choice task that creates a separating equilibrium between high-level Bayesian choice and lower-level reinforcement heuristic choice. Consistent with a dual systems framework, we hypothesize that glucose administration will both increase reaction...

Physical activity level is becoming more recognized as a primary factor in overall human health and obesity. Humans possess a number of traits that influence their physical activity level. We examined whether having a high or low desire to engage in challenging mental activity predicted...

In the current study we explore whether enriching the brain's supply of glucose will improve the quality and speed of decision making. Prior research shows that glucose enrichment supports cognition and more recent research has shown it can improve decision making on some tasks. To test our...

Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In...

When membership in a particular group conveys valuable information about an individual’s skills, productivity, or other human capital characteristics, a non-prejudiced agent may still find it rational to statistically discriminate. We frame statistical discrimination in a labor market setting...

Do individuals trained in law enforcement punish or rewards differently from typical student subjects? We analyze norm enforcement behavior of newly appointed police commissioners in both a Voluntary Contribution Mechanism game and a Common Pool Resource game. Our experimental design includes...

This study examines whether voluntary sleep restriction at commonly experienced levels impacts decision-making in a Bayesian choice task. Participants were largely traditional age college students from a regional state university (n=100) and a federal military academy (n=99). Sleep was measured...

Exercise is known to improve health along many dimensions. Decision making is an understudied dimension of one’s (behavioral) health where exercise effects are not well-known. Because certain physiological changes are known to impact decision making, exercise may modulate decisions via its...

We investigate the consistency and stability of individual risk preferences by slightly manipulating the cognitive resources of subjects through sleepiness. Participants are recruited and randomly assigned to an experiment session at a preferred time of day relative to their diurnal preference...

Punishment has been shown to be an effective reinforcement mechanism. Intentional or not, punishment will likely generate spillover effects that extend beyond one’s immediate decision environment, and these spillovers are not as well understood. We seek to understand these secondary spillover...
