In an experimental study we investigated effects of information amount and legal training on the judgment accuracy in legal cases. In a two (legal training: yes vs. no) x two (information amount: high vs. low) between-subjects design, 90 participants judged the premeditation of a perpetrator in...

Emotional reactions are an important element in the motivation to help others. Our research examined the role of affective vs. deliberative information processing in the genesis and use of emotional reactions in decisions to provide financial aid to people in distress. In two studies, we...

Impaired decision behavior of schizophrenia patients has been repeatedly observed. We investigated the aspects of the jumping to conclusions bias (JTC): biases in information-gathering, information weighting and integration, and overconfidence, using the process tracing paradigm Mouselab, which...

Classic behavioral decision research has intensively explored deliberate processes in decision making. Accordingly, individuals are viewed as bounded rational actors who, because of cognitive limitations, use simple heuristics that are successful in certain environments. In this chapter, it is...

Eine zentrale Aufgabe des Rechts besteht darin, das Zusammenleben in der Gesellschaft durch formale Regeln zu gewährleisten und diese gegebenenfalls an veränderte Anforderungen der Umwelt anzupassen. Dazu offnen sich Rechtswissenschaft und -praxis verstarkt gegenüber Befunden aus...

We claim that understanding human decisions requires that both automatic and deliberate processes be considered. First, we sketch the qualitative differences between two hypothetical processing systems, an automatic and a deliberate system. Second, we show the potential that connectionism offers...

Brandstätter, Gigerenzer and Hertwig (2006) put forward the priority heuristic (PH) as a fast and frugal heuristic for decisions under risk. According to the PH, individuals do not make trade-offs between gains and probabilities, as proposed by expected utility models such as cumulative...

Classic behavioral decision research has intensively explored deliberate processes in decision making. Accordingly, individuals are viewed as bounded rational actors who, because of cognitive limitations, use simple heuristics that are successful in certain environments. In this chapter, it is...

It has been repeatedly shown that in decisions under time constraints, individuals predominantly use noncompensatory strategies rather than complex compensatory ones. We argue that these findings might be due not to limitations of cognitive capacity but instead to limitations of information...

It has been shown that in decision making evaluations of evidence and attributes are modified. In three studies it was investigated if this finding of coherence shifts generalizes to real-world probabilistic inference decisions which are made from given probabilistic cues. Using a...
