Benedetto De Martino
Division of the Humanities and Social Sciences, California Institute of Technology, Pasadena, CA 91125, USA Department of Psychology, Royal Holloway University, London TW20 0EX, UK Electronic address
Neuron 79:1222-31. 2013
..Our results suggest that incorporating inferences about the intentions of others when making value judgments in a complex financial market could lead to the formation of market bubbles. ..
- Human insula activation reflects risk prediction errors as well as risk
Computation and Neural Systems Program and Division of Humanities and Social Sciences, Caltech, Pasadena, California 91125, USA
J Neurosci 28:2745-52. 2008
..As such, our findings indicate that our understanding of the neural basis of reward anticipation under uncertainty needs to be expanded to include risk prediction...
- Neural mechanisms underlying human consensus decision-making
Division of the Humanities and Social Sciences, California Institute of Technology, Pasadena, CA 91125, USA JSPS Postdoctoral Fellow, Graduate School of Letters, Hokkaido University, Sapporo, Hokkaido 060 0810, Japan Electronic address
Neuron 86:591-602. 2015
..Our findings provide support for a theoretical account in which collective decisions are made through integrating multiple types of inference about oneself, others, and environments, processed in distinct brain modules...
- The human brain encodes event frequencies while forming subjective beliefs
Computation and Neural Systems, California Institute of Technology, Pasadena, California 91125, USA
J Neurosci 33:10887-97. 2013
..Overall this study reveals the coexistence in the brain of an experience-based system of inference and a knowledge-based system of inference. ..
- Investigating signal integration with canonical correlation analysis of fMRI brain activation data
Division of Engineering and Applied Science, California Institute of Technology, Pasadena, CA 91125, USA
Neuroimage 41:35-44. 2008
..We show that the brain adds the signals of ER and risk to form a measure that activates the medial prefrontal cortex, consistent with the role of this brain structure in the evaluation of monetary gambles...
- Adding prediction risk to the theory of reward learning
Computational and Neural Systems, California Institute of Technology, Pasadena, CA 91125, USA
Ann N Y Acad Sci 1104:135-46. 2007
..Evidence is discussed that suggests that the dopaminergic system in the (human and nonhuman) primate brain encodes prediction risk, and that prediction errors are indeed scaled with prediction risk (adaptive encoding)...
- The role of the ventromedial prefrontal cortex in abstract state-based inference during decision making in humans
Alan N Hampton
Computation and Neural Systems Program, California Institute of Technology, Pasadena, California 91125, USA
J Neurosci 26:8360-7. 2006
..These results suggest that brain regions, such as the vmPFC, use an abstract model of task structure to guide behavioral choice, computations that may underlie the human capacity for complex social interactions and abstract strategizing...
- Neural correlates of mentalizing-related computations during strategic interactions in humans
Alan N Hampton
Computation and Neural Systems Program and Division of Humanities and Social Sciences, California Institute of Technology, 1200 East California Boulevard, M C 228 77, Pasadena, CA 91125, USA
Proc Natl Acad Sci U S A 105:6741-6. 2008
