Zusammenfassung

Understanding the subprocesses of risky decision making is a prerequisite for understanding (dys‐)functional decisions. For the present fMRI study, we designed a novel variant of the balloon‐analog‐risk task (BART) that measures three phases: decision making, reward anticipation, and feedback processing. Twenty‐nine healthy young adults completed the BART. We analyzed neural activity and functional connectivity. Parametric modulation allowed assessing changes in brain functioning depending on the riskiness of the decision. Our results confirm involvement of nucleus accumbens, insula, anterior cingulate cortex, and dorsolateral prefrontal cortex in all subprocesses of risky decision‐making. In addition, subprocesses were differentiated by the strength of activation in these regions, as well as by changes in activity and nucleus accumbens‐connectivity by the riskiness of the decision. The presented fMRI‐BART variant allows distinguishing activity and connectivity during the subprocesses of risky decision making and shows how activation and connectivity patterns relate to the riskiness of the decision. Hence, it is a useful tool for unraveling impairments in subprocesses of risky decision making in people with high risk behavior.
