Marco teórico neuroeconómico de la evaluación de riesgo bajo incertidumbre: interacción entre valoración (vmPFC), saliencia afectiva (amígdala) y control regulatorio

Abstract

La toma de decisiones financieras bajo incertidumbre constituye un problema central para la neuroeconomía porque integra procesos de valoración, emoción y control cognitivo en contextos de altoimpacto individual y colectivo. En este manuscrito se realiza una revisión teórica estructurada eintegradora de literatura conductual, neurofuncional y neurocomputacional, con actualización explícita de evidencia reciente (2020–2025), para explicar cómo emergen dos sesgos robustos —aversióna la pérdida y efecto encuadre— a partir de la interacción entre corteza prefrontal ventromedial(vmPFC), amígdala y sistemas de control regulatorio. Como contribución conceptual y mecanísticase propone un modelo causal multinivel (V–S–C) con formalización paramétrica mínima, distinciónfuncional entre constructos, hipótesis falsables preregistrables y predicciones separadas por nivel(conductual, neural y computacional). Asimismo, se especifica una agenda empírica con diseños experimentales prototipo y pipeline analítico (logística multinivel, SEM, GLM, ROI y conectividad).Se discuten implicaciones teóricas y aplicadas, junto con limitaciones conceptuales clave (inferenciainversa, validez ecológica y causalidad), con el objetivo de mover el campo desde marcos integradoresdescriptivos hacia teoría formal contrastable.
