Past research found that environmental uncertainty leads people to behave differently depending on their childhood environment. For example, economic uncertainty leads people from poor childhoods to become more impulsive while leading people from wealthy childhoods to become less impulsive. Drawing on life history theory, we examine the psychological mechanism driving such diverging responses t...

Impulsive differential systems are an important class of mathematical models for many practical systems in physics, chemistry, biology, engineering, and information science that exhibit impulsive dynamical behaviors due to abrupt changes at certain instants during the dynamical processes. This paper studies the controllability and observability of linear piecewise constant impulsive systems. Ne...

The received wisdom is that there is no known effective treatment for psychopathic disorders. Although outcome studies have not identified an effective programmatic treatment for psychopathic disorders, such studies tend to leave the question open. If behavioral science has not established that psychopathic disorders respond to a particular programmatic approach, neither are psychopathic disord...

This study aims to investigate the factors contributing online impulsive and compulsive buying behaviours among Vietnamese consumers, given increasing prevalence of shopping. A survey 562 participants (104 offline 548 online) Partial least squares structural equation model (PLS-SEM) were recruited empirically examine proposed research model. We found that (1) Performance Expectancy, Facilitatin...

A 55-year-old male with idiopathic Parkinson's disease developed three behavioral changes under combination therapy with selegiline, cabergoline and levodopa. Co-existent behaviors included severe pathological gambling, punding and novel skills in writing poetry (published poetry books). Brain [(18)F]fluorodopa PET imaging showed decreased tracer uptake in the striatum contralateral to the pred...
