This study employs a Discrete Choice Experiment (DCE) in the health-care sector to test the loss aversion theory that is derived from reference-dependent preferences: The absolute subjective value of a deviation from a reference point is generally greater when the deviation represents a loss...

We make hundreds of decisions every day, many of them extremely quickly and without much explicit deliberation. This motivates two important open questions: What is the minimum time required to make choices with above chance accuracy? What is the impact of additional decision-making time on...

Recent research has emphasized emotion's role in non-utilitarian judgments, but has not focused much on characteristics of subjects contributing to those judgments. The present article relates utilitarian judgment to individual disposition to experience various emotions. Study 1 first...

When people learn to make decisions from experience, a reasonable intuition is that additional relevant information should improve their performance. In contrast, we find that additional information about foregone rewards (i.e., what could have gained at each point by making a different choice)...

One of the largest reasons decision-makers make bad decisions (act imprudently) is that the world is full of uncertainty, we feel uncertain about the consequences of our actions. Participants played a repeated game in which decisions were made under various types of uncertainty (either no...

This study was designed to assess sex-related differences in the selection of an appropriate strategy when facing novelty. %This %basic behavior has been assumed to support more elaborate behaviors %like spatial abilities. A simple visuo-spatial task was used to investigate exploratory behavior...

Professional judges in traffic courts sentence many hundreds of offenders per year. Using 639 case files from archives, we compared the Matching Heuristic (MH) to compensatory, weighing algorithms (WM). We modeled and cross validated the models on different subsets of the data, and took several...

Third-party punishment has recently received attention as an explanation for human altruism. Feelings of anger in response to norm violations are assumed to motivate third-party sanctions, yet there is only sparse and indirect support for this idea. We investigated the impact of both anger and...

According to Unconscious Thought Theory (UTT: Dijksterhuis \& Nordgren, 2006), complex decisions are best made after a period of distraction assumed to elicit ``unconscious thought''. Over three studies, respectively offering a conceptual, an identical and a methodologically improved replication...

The present research aimed to test the role of mood in the Iowa Gambling Task (IGT; Bechara et al., 1994). In the IGT, participants can win or lose money by picking cards from four different decks. They have to learn by experience that two decks are overall advantageous and two decks are overall...
