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...

In this study we test predictions from Unconscious Thought Theory (UTT) that unconscious thought will lead to better decision making in complex decision tasks relative to conscious thought. Different from prior work testing this prediction, we use a method of manipulating conscious and...

Simple bargaining games are the foundation of more complex social interactions necessary for healthy relationships and well‐functioning societies. Neuroscience research has shown that high‐level deliberative thinking processes are necessary for social‐decision making - it seems cognitively...

This paper examines the impact of a commonly experienced adverse cognitive state on decision making under uncertainty. Specifically, we administer an at-home sleep restriction protocol combined with random assignment to the time-of-day for decision making. Thus, we induce sleepiness in our...

People differ in their diurnal (time-of-day) preferences—some are morning-types and others are evening-types. These differences are explored in a unique experiment design in which subjects are randomly assigned to produce paper airplanes at either 8:00 a.m. or 10:00 p.m. Our results show that...

We administer a unique online version of the Guessing Game where subject responses are collected across all 24 hours of the day. While time-of-day itself does not affect guesses, when combined with a trait-level sleepiness measure and previous night sleep, adverse sleep states lead to responses...

Research investigating risk preference has pointed towards motivation and ability as important factors for determining the strength and likelihood of the framing effect. In the current study we explored the influence of individual differences in motivation and ability through circadian rhythm....

We explore the behavioral consequences of sleep loss and time-of-day (circadian) effects on a particular type of decision making. Subject sleep is monitored for the week prior to a decision experiment, which is then conducted at 8 a.m. or 8 p.m. A validated circadian preference instrument allows...
