The rumen and its activity, rumination, are the characterizing traits of suborder Ruminantia, it is accompanied by related feeding habits consequent animal behavior. Several extrinsic (not to itself) factors affect rumination behavior; most reflected in timing (considering overall daily duration as well circadian differences patterns): age, environmental factors, diet. For these reasons, great ...

Depression is a disease that affects more women than men. One explanation why women are more frequently diagnosed with depression is that they cope with problems differently than men do. One such coping style, co-rumination, is the process of repeatedly talking about one’s problems without resolving them. While co-rumination is positively related to the quality of the friendship, it also correl...

In the current study, we examined the postulation that rumination makes it difficult for depressed individuals to learn the exact probability that different stimuli will be associated with punishment. To do so, we induced rumination or distraction in depressed and never-depressed participants and then measured punishment and reward sensitivity with a probabilistic selection task. In this task, ...

Research in developmental psychopathology and clinical staging models has increasingly sought to identify trans-diagnostic biomarkers or neurocognitive deficits that may play a role in the onset and trajectory of mental disorders and could represent modifiable treatment targets. Less attention has been directed at the potential role of cognitive-emotional regulation processes such as ruminative...

The main objective of the project was to examine a proposed theoretical model of mindfulness mechanisms in sports. We conducted two studies (the first study using a cross-sectional design and the second a longitudinal design) to investigate if rumination and emotion regulation mediate the relation between dispositional mindfulness and sport-specific coping. Two hundred and forty-two young elite...

BACKGROUND Overgeneral autobiographical memory has been identified as a risk factor for the onset and maintenance of depression. However, little is known about the underlying mechanisms that might explain overgeneral autobiographical memory phenomenon in depression. The purpose of this study was to test the mediation effects of rumination on the relationship between overgeneral autobiographical...

Extensive research has linked a greater female tendency to ruminate about depressed feelings or mood to the gender difference in depression. However, the developmental origins of the gender difference in depressive rumination are not well understood. We hypothesized that girls and women may be more likely to ruminate because rumination represents a gender-stereotyped coping style that is associ...

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship ...

Heightened emotional reactivity to peer feedback is predictive of adolescents' depression risk. Examining variation in emotional reactivity within currently depressed adolescents may identify subgroups that struggle the most with these daily interactions. We tested whether trait rumination, which amplifies emotional reactions, explained variance in depressed adolescents' physiological reactivit...

Previous work has demonstrated that individuals high (vs. low) in forgiveness are faster to rate their current thoughts and feelings toward their transgressor (i.e., their state forgiveness), but the underlying mechanism is still unclear. The present study examined whether individual differences in rumination about the transgression would mediate the association between forgiveness and response...
