Researchers in the Decision Science Hub at the Melbourne School of Psychological Sciences investigate the cognitive and neural mechanisms underlying human decision making. The hub facilitates a multidisciplinary approach, which will be critical to making important contributions to many complex multifactorial problems, which involve a lifetime of implicit and explicit decisions, such as chronic health challenges, mental health, obesity, cardiovascular health and cancer. This research will also contribute to an advanced understanding of related basic concepts, such as preferences and belief formation, decision errors and why people sometimes change their mind, neurotransmitters and how they influence decision processes, and the temporal rhythms in the brain underlying decision making.
