301 to 325 of 344Brief mindfulness induction could reduce aggression after depletion.
Many experiments have shown that one's ability to refrain from acting on aggressive impulses is likely to decrease following a prior act of self-control. This temporary state of self-control failure is known as ego-depletion. Although mindfulness is increasingly used to treat and manage aggressive behaviour, the extent to which mindfulness may counteract the depletion effect on aggression is yet to be determined. This study (N=110) investigated the effect of a laboratory induced one-time mindfulness meditation session on aggression following depletion. Aggression was assessed by the intensity of aversive noise blast participants delivered to an opponent on a computerised task. Depleted participants who received mindfulness induction behaved less aggressively than depleted participants with no mindfulness induction. Mindfulness also improved performance on a second measure of self-control…

Action orientation overcomes the ego depletion effect.
It has been consistently demonstrated that initial exertion of self-control had negative influence on people's performance on subsequent self-control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state-oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self-control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task.

Neural predictors of giving in to temptation in daily life.
The ability to control desires, whether for food, sex, or drugs, enables people to function successfully within society. Yet, in tempting situations, strong impulses often result in self-control failure. Although many triggers of self-control failure have been identified, the question remains as to why some individuals are more likely than others to give in to temptation. In this study, we combined functional neuroimaging and experience sampling to determine if there are brain markers that predict whether people act on their food desires in daily life. We examined food-cue-related activity in the nucleus accumbens (NAcc), as well as activity associated with response inhibition in the inferior frontal gyrus (IFG). Greater NAcc activity was associated with greater likelihood of self-control failures, whereas IFG activity supported successful resistance to temptations. These findings demons…

Perceived stress and health outcomes among Chinese university students: The chain mediating role of repetitive negative thinking and trait forgiveness.
Stress around COVID-19 among university students is associated with higher physical symptom burden and worse overall health status. This study examined whether RNT and trait forgiveness mediate the link between perceived stress and health outcomes among Chinese university students. A total of 1342 students participated in a survey during the middle of the semester that assessed perceived stress, RNT, trait forgiveness, and various health outcomes. Results revealed significant mediating effects of both RNT and trait forgiveness on the relationship between perceived stress and health outcomes, including anxiety, depression, sleep quality, and physical health. Moreover, the interplay between RNT and trait forgiveness mediated this association. These findings provide a theoretical basis for understanding the interactions among perceived stress, RNT, trait forgiveness, and health outcomes, hi…

The Roles of Delayed Cortical Maturation and Lower Anticipatory Reward Activation in Predicting Addictive Screen Use in Youth.
Background: Addictive screen use (ASU), above and beyond screen time, has been linked to significant mental health risks. Yet little is known about the neural risk factors that may associate with ASU. We examined 2 neurodevelopmental factors-cognitive control and reward-highlighted in substance use research and their links to ASU.
Methods: We utilized resting-state and monetary incentive delay (MID) task functional magnetic resonance imaging data from the Adolescent Brain Cognitive Development (ABCD) Study at baseline (Y0; ages 9-10 years) to predict addictive videogaming, addictive social media use, addictive phone use, and a composite measure of ASU at year 2 follow-up (Y2; ages 11-12 years). Cortical connectomic maturation was operationalized as distance from early life and proximity to adult functional networks in an individual connectome to potentially index cognitive control develo…

Short video addiction (SVA) has emerged as a growing behavioral and social issue, driven by the widespread use of digital platforms that provide highly engaging, personalized, and brief video content. We investigated the neuroanatomical and functional substrates of SVA symptoms, alongside brain transcriptomic and cellular characteristics, using Inter-Subject Representational Similarity Analysis (IS-RSA) and transcriptomic approaches. Behaviorally, we found that dispositional envy was associated with SVA. Structurally, SVA was positively correlated with increased morphological volumes in the orbitofrontal cortex (OFC) and bilateral cerebellum. Functionally, the dorsolateral prefrontal cortex (DLPFC), posterior cingulate cortex (PCC), cerebellum, and temporal pole (TP) exhibited heightened spontaneous activity, which was positively correlated with SVA severity.
