    Comparison of Decision Learning Models Using the Generalization Criterion Method.Woo-Young Ahn, Jerome R. Busemeyer, Eric-Jan Wagenmakers & Julie C. Stout - 2008 - Cognitive Science 32 (8):1376-1402.
    It is a hallmark of a good model to make accurate a priori predictions to new conditions (Busemeyer & Wang, 2000). This study compared 8 decision learning models with respect to their generalizability. Participants performed 2 tasks (the Iowa Gambling Task and the Soochow Gambling Task), and each model made a priori predictions by estimating the parameters for each participant from 1 task and using those same parameters to predict on the other task. Three methods were used to evaluate the (...)

    An improved cognitive model of the Iowa and Soochow Gambling Tasks with regard to model fitting performance and tests of parameter consistency.Junyi Dai, Rebecca Kerestes, Daniel J. Upton, Jerome R. Busemeyer & Julie C. Stout - 2015 - Frontiers in Psychology 6:126715.
    The Iowa Gambling Task (IGT) and the Soochow Gambling Task (SGT) are two experience-based risky decision-making tasks for examining decision-making deficits in clinical populations. Several cognitive models, including the expectancy-valence learning model (EVL) and the prospect valence learning model (PVL), have been developed to disentangle the motivational, cognitive, and response processes underlying the explicit choices in these tasks. The purpose of the current study was to develop an improved model that can fit empirical data better than the EVL and PVL (...)

    Regret in the context of unobtained rewards in criminal offenders.Melissa A. Hughes, Mairead C. Dolan & Julie C. Stout - 2014 - Cognition and Emotion 28 (5):913-925.
    In this study, we investigated whether differences in the experience of regret may be a potential explanation for damaging behaviours associated with psychopathy and criminal offending. Participants were incarcerated offenders (n = 60) and non-incarcerated controls (n = 20). Psychopathic traits were characterised with the Psychopathic Checklist: Screening Version. Regret was assessed by responses to outcomes on a simulated gambling task. Incarcerated offenders experienced a reduced sense of regret as compared to non-incarcerated controls. We obtained some evidence that specific psychopathic (...)
