Network analysis suggests working memory as a key target for facilitating subjective well-being Open
Using a Bayesian network approach, our findings point toward working memory as a potential key mechanism of well-being. Future work is needed to replicate these findings and determine the robustness of the identified network.

Ambulatory physiological state dynamics predict proximal behavioral markers of affect regulation in everyday life. Open
Human physiology reflects the body's capacity for self-regulation that is crucial for flexible adaptation to changing environmental demands. Leveraging wearable sensors and machine learning, we aimed to uncover latent physiological states …

Embodying well-being in research: Key principles and praxis Open
Research increasingly points to well-being as a public priority, integral to the health of individuals and communities. However, well-being research may be threatened by practices embedded in academic culture, given that 20-50% of young re…

The mind wanders to dark places: Mind-wandering catalyzes rumination in the context of negative affect and impulsivity. Open
Spontaneous mind-wandering has been theorized to increase susceptibility for rumination, contributing to risk for major depressive disorder (MDD). Clarifying whether-and under what circumstances-mind-wandering leads to rumination could inf…

Autonomic Inertia as a Proximal Risk Marker for Moments of Perseverative Cognition in Everyday Life in Remitted Depression Open
Background: Trait perseverative cognition (PC) is associated with inflexible autonomic activity and risk for depressive recurrence. However, the identification of dynamic psychophysiological markers of PC that fluctuate within individuals …

Autonomic complexity dynamically indexes affect regulation in everyday life. Open
Affect regulation often is disrupted in depression. Understanding biomarkers of affect regulation in ecologically valid contexts is critical for identifying moments when interventions can be delivered to improve regulation and may have uti…

A meta-analysis on the uncinate fasciculus in depression Open
Aberrant microstructure of the uncinate fasciculus (UNC), a white matter (WM) tract implicated in emotion regulation, has been hypothesized as a neurobiological mechanism of depression. However, studies testing this hypothesis have yielded…

Persistent Frustration-Induced Reconfigurations of Brain Networks Predict Individual Differences in Irritability Open
These pilot results suggest the importance of the postfrustration recovery period in the pathophysiology of irritability. Eglob in 3 specific posttask modules, involved in emotion processing, reward processing, or motor function, predicted…

The Risk of Guns on Suicide Open
Suicide is one of the leading causes of death in America. Every day, about 125 Americans take their own lives. Firearms play a vital role in this statistic, as around 60% of deaths by suicide involve the use of firearms. Evidence suggests …

Persistent frustration-induced reconfigurations of brain networks predict individual differences in irritability Open
Background Frustration, the response to blocked goal attainment, is a universal affective experience, but how the brain embodies frustration is not known. Understanding brain network dynamics during frustration may provide insight into ped…

The uncinate fasciculus in individuals with and at risk for bipolar disorder: A meta-analysis Open
Our findings support aberrant UF microstructure, potentially related to alterations in myelination, as a mechanism, but not as an endophenotype of BD. However, given the limited power in the REL subsample, the latter finding must be consid…

The role of the uncinate fasciculus in the risk-architecture of bipolar disorders: A meta-analysis Open
Background Bipolar disorder (BD) is a severe mental disorder, characterized by prominent mood swings and emotion regulation (ER) deficits. The uncinate fasciculus (UF), a white matter tract connecting the amygdala and the ventral prefronta…
