The strength of decision routines was manipulated within a computer controlled micro-world simulation which required that participants make recurrent acquisition and disposal decisions. One week after having learned weak or strong routines, participants were confronted with changes in this...

The fast-and-frugal heuristics approach to probabilistic inference assumes that individuals often employ simple heuristics to integrate cue information that commonly function in a non-reciprocal fashion. Specifically, the subjective validity of a certain cue remains stable during the application...

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...

This paper presents a computer controlled micro-world simulation (COMMERCE) to study routine effects in deliberate repeated decision making. COMMERCE employs an economic scenario which requires the participant to recurrently make acquisition and disposal decisions of industrial goods in order to...

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...

There is an ongoing debate whether frequency judgments are based on mental magnitudes reflecting prior on-line recording of frequencies or on recall content available at the time of judgment. We conducted four experiments to demonstrate that task characteristics can determine which kind of...
