This project tests the hypothesis that interoception (the perception of the body’s internal state) plays a fundamental role in decision-making. By utilising multiple, interdisciplinary techniques to address this question, including genetics, longitudinal modelling, casual inference methods, physiology, electroencephalography and machine learning, this project will provide the most comprehensive test of the somatic marker hypothesis to date. This project will shed light on individual differences in decision-making and interoception and the extent to which these factors are related at the genetic, behavioural and neuroscientific level, contributing to theory concerning the role of interoception in decision-making.
