But whether the level of rewards also influences how well it can be learned to make correct decisions is still relatively unclear. This research examines how the level of rewards interacts with feedback on right and wrong decisions when learning a new decision-making task or category assignment.</p> Content content-216307 Thu, 05 Mar 2026 18:29:23 +0100 Mathematical modeling of judgment processes, category learning and sequential decisions https://www.uni-bremen.de/en/general-psychology/research#c216307 <p class="tw-data-text tw-text-large tw-ta">We develop and test formal mathematical models of judgment, categorization, and decision-making. We use these models to make quantitative predictions about decision-making behavior and to understand how human behavior changes in different environments and task structures.</p> Content content-216310 Thu, 05 Mar 2026 18:29:23 +0100 Age-related changes in decision-making behavior https://www.uni-bremen.de/en/general-psychology/research#c216310 <p class="tw-data-text tw-text-large tw-ta">Aging is accompanied by a series of cognitive, emotional, and motivational changes that also influence decision-making behavior. We are working on projects that examine how the role of social information in the decision-making process changes with age.</p> Content content-216313 Thu, 05 Mar 2026 18:29:23 +0100 Process tracing of information search in memory https://www.uni-bremen.de/en/general-psychology/research#c216313 <p class="tw-data-text tw-text-large tw-ta">The search for information in memory usually eludes direct observation. The goal of this research project is to apply and develop a new method that examines the retrieval of information from memory based on the recording of eye movements. In particular, we explore the extent to which this method can be used to investigate what information people retrieve from memory during a decision.</p> Content
