This project is part of the interdisciplinary DFG Research Unit Psychoeconomics: Interacting Decision Processes and Their Consequences for Economic Performance.
The goal of our project is to investigate and model the dynamics of decision making under conflict, where we are especially interested in conflicts that result from interfering dual processes, i.e. from opposite choice tendencies generated by automatic and controlled decision processes, respectively. We are interested in how decision makers resolve such conflicts and how they trade speed for accuracy. For this objective, we will systematically manipulate the speed and accuracy of the decisions by means of deadlines and/or monetary incentives. We expect that under speed pressure decision-makers mainly lower their decision criterion, i.e. come to a decision with less evidence, but largely avoid additional mental effort. In contrast, when they get paid for an optimal performance, then we assume that the decision-makers increase their effort.
Recently, we also investigate value-based decisions.
The project was funded by several grants from the Universität Konstanz and the German Science Foundation (DFG)
