Unlike the strategy of cognitive regulation that relies heavily on the top-down control function of the prefrontal cortex (PFC), which was recently found may be critically impaired in stressful situations, traditional Chinese philosophy and medicine views different types of emotionality as having mutual promotion and counteraction (MPMC) relationships, implying a novel approach that requires le...

Early identification of sick cattle increases treatment success and decreases mortality. Continuous automated records of behavior can be used to identify sick cattle early in the disease process. The objective was to evaluate accuracy of an ear-attached accelerometer (SensOor) that quantified ear movements and estimated feeding and rumination time through a proprietary algorithm. Accelerometers...

Worry and rumination are closely allied cognitive processes that impact on the experience of anxious and depressive symptoms. Using a prospective design, this study examined overlapping and distinct features of worry and rumination in relation to symptoms and coping behavior in a nonclinical sample of Singaporean college students. Worry and rumination were highly correlated, but they retained d...

This study examined the relationship between meaning making and rumination regarding stressful events. We focused on two facets of rumination: intrusive and deliberate. Participants (N = 121) completed a questionnaire about a stressful event in their life that assessed the possibility of preventing the event, probability of the event occurring, perceived threat of the event, and meaning making....

An increasing number of research studies have suggested that metacognition is associated with individuals' mental health. Specifically, metacognitive beliefs about rumination was proposed to link to the onset and maintenance of depression according to the metacognitive model of depression. The current study aimed to serve as a pilot study exploring how parents' metacognitive beliefs and parenti...

Both rumination and attentional biases have been proposed as key components of the RDoC Negative Valence Systems construct of Loss. Although theorists have proposed that rumination, particularly brooding rumination, should be associated with increased sustained attention to depression-relevant information, it is not clear whether this link would be observed in a non-depressed sample or whether ...

Objective. Prior research has found consistent support that rumination and insomnia are important risk factors for depressive symptoms. The aim of the present cross-sectional study is to examine the interaction between these two previously well-established risk factors (i.e., rumination and insomnia) in the explanation of depressive symptoms. Design. A total of 417 participants (277 women) with...

Individuals with acquired brain injuries (ABI) often experience depression following injury, with estimated rates between 20 and 40% within the first year and up to 50% thereafter (Fleminger et al., 2003). Previous studies with non-brain-injured individuals have identified that rumination is prevalent in both the development and maintenance of depression. The study aimed to explore how depressi...

This study examined the effectiveness and feasibility of therapist-guided Internet-delivered exposure (EX) and behavioral activation (BA) for complicated grief and rumination. Forty-seven bereaved individuals with elevated levels of complicated grief and grief rumination were randomly assigned to three conditions: EX (N=18), BA (N=17), or a waiting-list (N=12). Treatment groups received 6 homew...

Cardiovascular responses occur not only in the immediate presence of stressors, but also while later thinking about those experiences. Evidence suggests that these delayed responses, such as those produced by ruminating about prior angering experiences, may play an important role in the development of cardiovascular disease. We examine whether physiological consequences of rumination depend on ...
