PEREZ-RIVERO, Paula Fernanda  and  MIELES-TOLOZA, Ismael Leonardo. Explanatory neuroeconomics models of the relation between risk-aversion, impulsivity and cardioception in university students: a scoping review. Medicas UIS [online]. 2023, vol.36, n.1, pp.85-102.  Epub May 04, 2023. ISSN 0121-0319.


neuroeconomic models explain decision making based on neurophysiological, cognitive, and emotional processes. Decision making is studied from other threads such as risk aversion. The relationship between risk aversion, impulsivity and/or interoception is important to determine the role of human behavior and cognition in the maintenance of health problems. This has been studied in the university population, in which health risk factors are present.


to synthesize the neuroeconomic models described in the literature to establish the relationship between risk aversion, impulsivity and/or cardioception in university students.


scoping review carried out from June 1 to September 30, 2021, in the resources; PubMed, PsyInfo, Google Scholar, Sciencedirect, Scopus, Open dissertations, and OpenGrey. As inclusion criteria, it was established that they were experimental and observational investigations in English or Spanish in university students that evaluated the relationship between decision-making, impulsivity and/or interoception. It was not filtered by date or by type of access.


1035 documents were searched, 14 met the inclusion criteria. Four models were identified: behavioral neuroeconomic, delaying discount paradigm, Gray’s biopsychological theory, and individual differences. Positive and negative correlations were found between impulsivity, risk aversion, and interoception.


according to the studies, there is a relationship between impulsivity and risk aversion, which depending on the model implemented will be positive or negative. Associations with interoception are inconclusive and require further investigation.
