Published in: Topics in Cognitive Science, Volume 10, Issue 1, 175-191 Abstract “Rumination is a process of uncontrolled, narrowly focused negative thinking that is often self‐referential, and that is a hallmark of depression. Despite its importance, little is known about its cognitive mechanisms. Rumination can be thought of as a specific, constrained form of mind‐wandering. Here, we introduce a cognitive model of rumination that we developed on the basis of our existing model of mind‐wandering. The rumination model implements the hypothesis that rumination is caused by maladaptive habits of thought. These habits of thought are modeled by adjusting the number of… Read More
The relation between rumination and temporal features of emotion intensity
Published in: Cognition and Emotion, Volume 32, Issue 2, 259-274 Abstract “Intensity profiles of emotional experience over time have been found to differ primarily in explosiveness (i.e. whether the profile has a steep vs. a gentle start) and accumulation (i.e. whether intensity increases over time vs. goes back to baseline). However, the determinants of these temporal features remain poorly understood. In two studies, we examined whether emotion regulation strategies are predictive of the degree of explosiveness and accumulation of negative emotional episodes. Participants were asked to draw profiles reflecting changes in the intensity of emotions elicited either by negative social feedback in… Read More
