Decision making

In this research stream, headed by Bernd Figner, we focus on studying the psychological and neural processes in individual decision making. In particular, we are interested in understanding group and individual differences in risky choice and risk taking, intertemporal choice and impulsivity, as well as in ambiguity, i.e., when information about the possible decision outcomes is imprecise, for example information about the probability or timing of decision outcomes.

We study adaptive and maladaptive forms of such decisions and the role of different psychological and neural processes—including affective versus deliberative processes, self-control, and instrumental versus Pavlovian processes—in healthy adult populations, developing populations (with a focus on adolescence), and clinical populations. In our studies, we typically combine different methodological approaches such as sophisticated behavioral tasks (e.g., the Columbia Card Task), computational modeling, brain stimulation and brain imaging methods, as well as psychological and pharmacological interventions to triangulate our research findings and work towards converging empirical evidence.
