Researchers have been interested in how human beings accumulate and process information for decision-making since the development of experimental psychology in the late nineteenth century and then its renaissance in cognitive science in the 1960s. Whereas psychometrics and test theory, which also got their start in the nineteenth century have made individual differences the foundation of their ...

Excessively choosing immediate over larger future rewards, or delay discounting (DD), associates with multiple clinical conditions. Individual differences in DD likely depend on variations in the activation of and functional interactions between networks, representing possible endophenotypes for associated disorders, including alcohol use disorders (AUDs). Numerous fMRI studies have probed the ...

Groups typically express more confidence than individuals, yet how individual-level confidence combines during collaborative decision tasks is not well understood. We prescreened 686 community members using a novel confidence measure (a true/false trivia test) intentionally designed to be difficult (accuracy rates were not significantly better than chance) and randomly assigned 72 individuals t...

Wayfinding is an important aspect that should be considered by tourist park managers when allocating resources and facilities to aid tourists navigating their way through a park. This paper discusses the influence of individual differences such as age, gender, travel group, and familiarity with the environment towards the wayfinding decision making process and physical movement. A case study wa...

In risky decision-making, expected utility (EU) theory is widely used to examine people's risk attitude and choice behavior. However, it is unknown how risk attitude relates to attention and information search. In this paper, we explore the relationship between risk attitude (as measured by a variant of EU) and eye movement patterns (which serve as a proxy for attention and information search)....

This study asks to what extent (a) individuals show consistent performance differences across typical behavioral decision-making tasks, and (b) how those differences correlate with plausible real-world correlates of good decision making. Seven tasks, chosen to span the domain of decision-making skills, were administered to participants in an ongoing longitudinal study providing extensive social...
