The neural foundations of the Dark Triad (DT) personality traits—narcissism, Machiavellianism, and psychopathy—remain largely unexplored despite their profound impact on social behavior. Previous research has indicated potential structural and functional alterations in the default mode network (DMN) and reward-related regions in individuals exhibiting high levels of DT traits. However, these...

Abstract Recent findings challenge traditional views of the Default Mode Network (DMN) as purely task-negative or self-oriented, showing increased DMN activity during demanding switches between externally-focused tasks (Crittenden et al., 2015; Smith et al., 2018; Zhou et al., 2024). However, it is unclear what modulates the DMN at switches, with transitions within a stimulus domain activating...

Abstract The default mode network is a brain network processing mental states featuring an internal representation of subjective experiences like autobiographical episodic memory retrieval and a resting state. If the default mode network is the common spatial domain processing such mental states, then the temporal domain might present the differences in the mental states. To detect adaptations...

Abstract Everyday cognitive functioning is characterized by constant alternations between different modes of information processing, driven by fluctuations in environmental demands. At the neural level, this is realized through corresponding dynamic shifts in functional activation and network connectivity. A distinction is often made between the Default Mode Network (DMN) as a task-negative...

Abstract The default mode network (DMN) has been theorized to participate in a range of social, cognitive, and affective functions. Yet, previous accounts do not consider how the DMN contributes to other brain regions depending on psychological context, thus rendering our understanding of DMN function incomplete. We addressed this gap by applying a novel network-based psychophysiological...

Training in mindfulness has been shown to improve a variety of psychological disorders as well as physical conditions. Additionally, mindfulness training has been shown to reduce risk-taking behaviors following several weeks of training. Reducing risk-taking behaviors is of particular importance in regard to specific mental health problems, such as substance use and eating disorders. Many...

Vipassana meditation is characterized by observing bodily sensations, developing emotional and attentional stability and promoting pro-social qualities. Whether these qualities are also reflected in dream content is not currently known. Evidence relating dream content with sleep-depending learning is mixed: some studies suggest that dreaming of a task is beneficial for improvement, while others...

Study objectives: Rapid eye movement (REM) sleep, non-rapid eye movement (NREM) sleep, and sleep spindles are all implicated in the consolidation of procedural memories. The relative contributions of sleep stages and sleep spindles was previously shown to depend on individual differences in task processing. Experience with Vipassana meditation is one such individual difference that has not been...

Mindfulness Based Cognitive Therapy (MBCT) was developed to combine methods from cognitive behavioural therapy and meditative techniques, with the specific goal of preventing relapse in recurrent depression. While supported by empirical evidence from multiple clinical trials, the cognitive mechanisms behind the effectiveness of MBCT are not well understood in computational (information...

Mindfulness-based interventions (MBIs) are increasingly used to promote mental health and resilience, yet their applicability within racially marginalized communities remains underexplored. Ethiopian-Israeli young adults face chronic stressors related to socioeconomic disadvantage, racialized discrimination, and complex identity negotiations, creating a distinctive context in which mindfulness...
