Abstract

the reinforcement/extinction disorder hypothesis (sagvolden et al.) is an important counterweight to the executive dysfunction model of attention-deficit/hyperactivity disorder (adhd). however, like that model, it conceptualises adhd as pathophysiologically homogeneous, resulting from a common core dysfunction. recent studies reporting neuropsychological heterogeneity suggest that this common core dysfunction may be the scientific equivalent of a red herring.
