Behavioural and neurobiological foundations of human adaptation to leptokurtosis

Human response to evolutionary novel leptokurtic noise, focusing on neurobiological mechanisms


Large-scale human interaction through, for example, financial markets causes ceaseless random changes in outcome variability, producing frequent and salient outliers that render the outcome distribution more peaked than the Gaussian distribution, and with longer tails. We have been studying how humans cope with this evolutionary novel leptokurtic noise, focusing on the neurobiological mechanisms that allow the brain to (1) recognize the outliers as noise and (2) regulate the control necessary for adaptive response.
