251 to 275 of 1,075Testing the validity of the attention control video: An eye-tracking approach of the ego depletion effect.
The attention control video has been frequently applied to test the ego depletion effect. However, its validity has never been tested, a shortcoming we address in this preregistered study. In the first task, self-control strength was temporarily depleted in the depletion condition (n = 56) but remained intact in the control condition (n = 56). The attention control video served as the secondary task, and we assumed that the depletion condition would perform significantly worse compared to the control condition. Attention regulation was measured with an eye-tracking device. The results revealed that the gaze behavior in the two conditions differed statistically significantly; however, the actual difference was small, indicating that the attention control video may not be an optimal measure of self-control.

Introduction: Obesity and associated diseases place a severe burden on healthcare systems. Behavioural interventions for weight loss (WL) are successful in the short term but often result in weight regain over time. Self-regulation of eating and activity behaviours may significantly enhance weight loss maintenance (WLM) and may be effectively augmented by contextual behavioural approaches to emotion regulation. The NoHoW trial tests the efficacy of a theoretically informed, evidence-based digital toolkit using a mobile-enabled website, activity trackers and Wi-Fi scales for WLM aiming to target (1) self-regulation and motivation, and (2) emotion regulation in adults who achieved clinically significant (≥5%) WL in the previous 12 months (initial body mass index (BMI) ≥25 kg/m2).
Methods and analysis: The study is an 18-month, 3-centre, 2×2 factorial single-blind, randomised controlled tri…

Effect of a Yoga Based Meditation Technique on Emotional Regulation, Self-compassion and Mindfulness in College Students.
Background: Emotion regulation is often a challenge for the college students. Yoga practice has been shown to reduce stress and improve mindfulness that is related to emotion regulation. Mastering emotions technique (MEMT) is one of the yoga-based meditation techniques that are designed to control emotions among practitioners. However, to the best of our knowledge, there is no known study reporting its scientific evidence-based effects on emotion and its related variables. Thus, this study was conducted to evaluate the effect of MEMT on emotion regulation, self-compassion, and mindfulness in college students.
Materials and methods: Seventy-two subjects with the age varied from 18 to 25 years were recruited from a residential college. All the subjects underwent MEMT for the duration of 45 min a day for a period of 2 weeks. Assessments such as Emotional Regulation Questionnaire (ERQ), The …

Brain stimulation reveals crucial role of overcoming self-centeredness in self-control.
Neurobiological models of self-control predominantly focus on the role of prefrontal brain mechanisms involved in emotion regulation and impulse control. We provide evidence for an entirely different neural mechanism that promotes self-control by overcoming bias for the present self, a mechanism previously thought to be mainly important for interpersonal decision-making. In two separate studies, we show that disruptive transcranial magnetic stimulation (TMS) of the temporo-parietal junction-a brain region involved in overcoming one's self-centered perspective-increases the discounting of delayed and prosocial rewards. This effect of TMS on temporal and social discounting is accompanied by deficits in perspective-taking and does not reflect altered spatial reorienting and number recognition. Our findings substantiate a fundamental commonality between the domains of self-control and social…

Effects of a mindfulness-based intervention on fertility quality of life and pregnancy rates among women subjected to first in vitro fertilization treatment.
Generally, undergoing an in vitro fertilization (IVF) treatment is an emotional and physical burden for the infertile woman, which may negatively influence the treatment outcome. We conducted a study to investigate the effectiveness of a mindfulness-based intervention (MBI) among women subjected to first IVF treatment at a fertility medical center in China. Among infertile women registered for their first IVF treatment, 58 completed the intervention, and 50 were assigned to a control group using a non-randomized controlled study. Standardized measures of mindfulness, self-compassion, emotion regulation difficulties, infertility-related coping strategies and fertility quality of life (FertiQoL) were endorsed pre- and post-MBI, and measure of pregnancy rates at the sixth months after the intervention. Both groups were shown to be equivalent at baseline. By the end of the intervention, wome…

Efficacy of quetiapine for impulsivity and affective symptoms in borderline personality disorder.
Data on the efficacy of quetiapine in borderline personality disorder (BPD) are still scarce. We aimed to investigate the efficacy of quetiapine for impulsivity and a broad range of affective symptoms in BPD. In this 12-week open-label study, we included individuals with BPD who presented to psychiatric in- and outpatient services. After a gradual titration of quetiapine, a flexible dose (range, 100-800 mg) was administered. The main outcome measures consisted of the scores on patient-rated questionnaires (Barratt Impulsiveness Scale, Buss-Durkee Hostility Inventory, Affective Lability Scale, Spielberger State and Trait Anxiety Inventory, Spielberger State and Trait Anger Inventory, and Beck Depression Inventory) and on neurocognitive tasks related to impulsivity (Stroop Color Word Task and IOWA Gambling Task). A mixed linear model, correcting for age, sex, antidepressant use, and weeks …

Impulsive action and impulsive choice across substance and behavioral addictions: cause or consequence?
Substance use disorders are prevalent and debilitating. Certain behavioral syndromes ('behavioral addictions') characterized by repetitive habits, such as gambling disorder, stealing, shopping, and compulsive internet use, may share clinical, co-morbid, and neurobiological parallels with substance addictions. This review considers overlap between substance and behavioral addictions with a particular focus on impulsive action (inability to inhibit motor responses), and impulsive choice (preference for immediate smaller rewards to the detriment of long-term outcomes). We find that acute consumption of drugs with abuse potential is capable of modulating impulsive choice and action, although magnitude and direction of effect appear contingent on baseline function. Many lines of evidence, including findings from meta-analyses, show an association between chronic drug use and elevated impulsiv…

Decision-making in the adolescent brain.
Adolescence is characterized by making risky decisions. Early lesion and neuroimaging studies in adults pointed to the ventromedial prefrontal cortex and related structures as having a key role in decision-making. More recent studies have fractionated decision-making processes into its various components, including the representation of value, response selection (including inter-temporal choice and cognitive control), associative learning, and affective and social aspects. These different aspects of decision-making have been the focus of investigation in recent studies of the adolescent brain. Evidence points to a dissociation between the relatively slow, linear development of impulse control and response inhibition during adolescence versus the nonlinear development of the reward system, which is often hyper-responsive to rewards in adolescence. This suggests that decision-making in ado…

Laboratory paradigms of impulsivity and alcohol dependence: a review.
Impulsivity can be defined as choosing a smaller, immediate reward over a larger, delayed reward. From this perspective, addictive behaviors such as substance abuse and pathological gambling reflect a series of impulsive choices. However, impulsivity is not a homogeneous construct. Laboratory measures of impulsivity reflect two types of processes. The first is related to behavioral inhibition and refers to an individual's ability to appropriately inhibit thoughts or actions. The second is the delay of reward dimension, namely the degree to which immediate (rewarding) consequences have more control over an individual's behavior than consequences that are delayed. In this review, we describe how alcohol is associated with significant impairments in these paradigms. We also suggest that they may have a role in the development of alcohol dependence. These results are in agreement with a mode…

Dynamic brain network configurations during rest and an attention task with frequent occurrence of mind wandering.
Mind wandering (MW) has become a prominent topic of neuroscientific investigation due to the importance of understanding attentional processes in our day-to-day experiences. Emerging evidence suggests a critical role for three large-scale brain networks in MW: the default network (DN), the central executive network (CEN), and the salience network (SN). Advances in analytical methods for neuroimaging data (i.e., dynamic functional connectivity, DFC) demonstrate that the interactions between these networks are not static but dynamically fluctuate over time (Chang & Glover, 2010, NeuroImage, 50(1), 81-98). While the bulk of the evidence comes from studies involving resting-state functional MRI, a few studies have investigated DFC during a task. Direct comparison of DFC during rest and task with frequent MW is scarce. The present study applies the DFC method to neuroimaging data collected fr…

Common and differential neural networks of emotion regulation by Detachment, Reinterpretation, Distraction, and Expressive Suppression: a comparative fMRI investigation.
Emotions are an indispensable part of our mental life. The term emotion regulation refers to those processes that influence the generation, the experience and the expression of emotions. There is a great variety of strategies to regulate emotions efficiently, which are used in daily life and that have been investigated by cognitive neuroscience. Distraction guides attention to a secondary task. Reinterpretation, a variant of cognitive reappraisal, works by changing the meaning of an emotional stimulus. Detachment, another reappraisal strategy, refers to distancing oneself from an emotional stimulus, thereby reducing its personal relevance. Expressive Suppression modifies the behavioral or physiological response to an emotional stimulus. These four strategies are not equally effective in terms of emotion regulation success and have been shown to partly rely on different neuronal systems. …

Previous studies have documented the positive effects of mindfulness meditation on executive control. What has been lacking, however, is an understanding of the mechanism underlying this effect. Some theorists have described mindfulness as embodying two facets-present moment awareness and emotional acceptance. Here, we examine how the effect of meditation practice on executive control manifests in the brain, suggesting that emotional acceptance and performance monitoring play important roles. We investigated the effect of meditation practice on executive control and measured the neural correlates of performance monitoring, specifically, the error-related negativity (ERN), a neurophysiological response that occurs within 100 ms of error commission. Meditators and controls completed a Stroop task, during which we recorded ERN amplitudes with electroencephalography. Meditators showed greate…

Hayden BY (2016)reviewMEDLINE-indexed journal, not yet read by usPsychonomic bulletin & review78 citations Time discounting and time preference in animals: A critical review.
Animals are an important model for studies of impulsivity and self-control. Many studies have made use of the intertemporal choice task, which pits small rewards available sooner against larger rewards available later (typically several seconds), repeated over many trials. Preference for the sooner reward is often taken to indicate impulsivity and/or a failure of self-control. This review shows that very little evidence supports this assumption; on the contrary, ostensible discounting behavior may reflect a boundedly rational but not necessarily impulsive reward-maximizing strategy. Specifically, animals may discount weakly, or even adopt a long-term rate-maximizing strategy, but fail to fully incorporate postreward delays into their choices. This failure may reflect learning biases. Consequently, tasks that measure animal discounting may greatly overestimate the true discounting and may…

Ego Does Not Deplete Over Time.
The idea that self-control (or executive) functions depend on limited "mental resources" that can be depleted (aka ego-depletion) has generated a lot of interest, but both the empirical status of the phenomenon and its theoretical explanation remain controversial. Here, we tested a widely neglected but straightforward prediction of ego-depletion theory: The longer people work on a control-demanding task, the more should their ego deplete. If so, ego-depletion effects should become more pronounced as time on (control) task increases. To test that prediction, we carried out an online experiment, in which participants switched between blocks of a numerical Stroop task (NST) with either 50% or 10% incongruent trials, which served to induce different degrees of ego depletion, and a Global-Local Task (GLT), which served to measure the impact of ego depletion. We predicted that participants wou…

Exposure to nature counteracts aggression after depletion.
Acts of self-control are more likely to fail after previous exertion of self-control, known as the ego depletion effect. Research has shown that depleted participants behave more aggressively than non-depleted participants, especially after being provoked. Although exposure to nature (e.g., a walk in the park) has been predicted to replenish resources common to executive functioning and self-control, the extent to which exposure to nature may counteract the depletion effect on aggression has yet to be determined. The present study investigated the effects of exposure to nature on aggression following depletion. Aggression was measured by the intensity of noise blasts participants delivered to an ostensible opponent in a competition reaction-time task. As predicted, an interaction occurred between depletion and environmental manipulations for provoked aggression. Specifically, depleted pa…

Group Influences on Engaging Self-Control: Children Delay Gratification and Value It More When Their In-Group Delays and Their Out-Group Doesn't.
Self-control emerges in a rich sociocultural context. Do group norms around self-control influence the degree to which children use it? We tested this possibility by assigning 3- to 5-year-old children to a group and manipulating their beliefs about in-group and out-group behavior on the classic marshmallow task. Across two experiments, children waited longer for two marshmallows when they believed that their in-group waited and their out-group did not, compared with children who believed that their in-group did not wait and their out-group did. Group behavior influenced children to wait more, not less, as indicated by comparisons with children in a control condition who were assigned to a group but received no information about either groups' delay behavior (Experiment 1). Children also subsequently valued delaying gratification more if their in-group waited and their out-group did not …

Why self-control seems (but may not be) limited.
Self-control refers to the mental processes that allow people to override thoughts and emotions, thus enabling behavior to vary adaptively from moment to moment. Dominating contemporary research on this topic is the viewpoint that self-control relies upon a limited resource, such that engaging in acts of restraint depletes this inner capacity and undermines subsequent attempts at control (i.e., ego depletion). Noting theoretical and empirical problems with this view, here we advance a competing model that develops a non-resource-based account of self-control. We suggest that apparent regulatory failures reflect the motivated switching of task priorities as people strive to strike an optimal balance between engaging cognitive labor to pursue 'have-to' goals versus preferring cognitive leisure in the pursuit of 'want-to' goals.

Executive functioning, emotion regulation, eating self-regulation, and weight status in low-income preschool children: how do they relate?
The purpose of the present study was to examine relationships between child eating self-regulation, child non-eating self-regulation, and child BMIz in a low-income sample of Hispanic families with preschoolers. The eating in the absence of hunger task as well as parent-report of child satiety responsiveness and food responsiveness were used to assess child eating self-regulation. Two laboratory tasks assessing executive functioning, a parent questionnaire assessing child effortful control (a temperament dimension related to executive functioning), and the delay of gratification and gift delay tasks assessing child emotion regulation were used to assess child non-eating self-regulation. Bivariate correlations were run among all variables in the study. Hierarchical linear regression analyses assessed: (1) child eating self-regulation associations with the demographic, executive functionin…

Sen A, Tai XY (2023)reviewMEDLINE-indexed journal, not yet read by usCurrent neurology and neuroscience reports47 citations Sleep Duration and Executive Function in Adults.
Purpose of review: To review the literature examining the relationship between sleep and cognition, specifically examining the sub-domain of executive function. We explore the impact of sleep deprivation and the important question of how much sleep is required for optimal cognitive performance. We consider how other sleep metrics, such as sleep quality, may be a more meaningful measure of sleep. We then discuss the putative mechanisms between sleep and cognition followed by their contribution to developing dementia.
Recent findings: Sleep duration and executive function display a quadratic relationship. This suggests an optimal amount of sleep is required for daily cognitive processes. Poor sleep efficiency and sleep fragmentation are linked with poorer executive function and increased risk of dementia during follow-up. Sleep quality may therefore be more important than absolute duration…

The neurobiology of drug addiction: cross-species insights into the dysfunction and recovery of the prefrontal cortex.
A growing preclinical and clinical body of work on the effects of chronic drug use and drug addiction has extended the scope of inquiry from the putative reward-related subcortical mechanisms to higher-order executive functions as regulated by the prefrontal cortex. Here we review the neuroimaging evidence in humans and non-human primates to demonstrate the involvement of the prefrontal cortex in emotional, cognitive, and behavioral alterations in drug addiction, with particular attention to the impaired response inhibition and salience attribution (iRISA) framework. In support of iRISA, functional and structural neuroimaging studies document a role for the prefrontal cortex in assigning excessive salience to drug over non-drug-related processes with concomitant lapses in self-control, and deficits in reward-related decision-making and insight into illness. Importantly, converging insigh…

Potential Benefits of Physical Activity in MCI and Dementia.
Physical activity improves overall health and reduces the risk of many negative health outcomes and may be effective in improving cognition, independent functioning, and psychological health in older adults. Given the evidence linking physical activity with improvements in various aspects of health and functioning, interventions exploring pathways for decreasing risk of dementia in those with mild cognitive impairment (MCI) and improving outcomes for those with dementia are of critical importance. The present review highlights the work examining physical activity interventions in order to achieve a comprehensive understanding of the potential benefits of physical activity for individuals experiencing cognitive decline. The primary focus is on aerobic exercise as this is the main intervention in the literature. Our review supports the thesis that physical activity can promote healthy agin…

Brain default-mode network dysfunction in addiction.
Aberrant patterns of brain functional connectivity in the default mode network (DMN) have been observed across different classes of substance use disorder (SUD) and are associated with craving and relapse. In addicted individuals resting functional connectivity (RSFC) of the anterior DMN, which participates in attribution of personal value and emotional regulation, tends to be decreased, whereas RSFC of the posterior DMN, which directs attention to the internal world, tends to be increased. Aberrant RSFC within the DMN is believed to contribute to impaired self-awareness, negative emotions and to ruminations in addiction. Additionally, the disrupted connectivity between DMN and cortical regions involved with executive function, memory and emotion could be critical to drug-taking regardless of negative consequences and to stress-triggered relapse. At the system level, the dynamics of DMN …

Remediation of depression-related cognitive impairment: cognitive control training as treatment augmentation.
Introduction: Despite several available evidence-based interventions for major depression relapse, rates remain high and relapse prevention programs are still scarce. To increase effectiveness, novel techniques that target underlying vulnerability factors may be a promising avenue. Depression is associated with impairments in executive functioning, which is in turn associated with poor psychosocial outcomes and more Repetitive Negative Thinking (RNT), a key vulnerability factor for relapse. This paper examines deficits in cognitive control as a potentially modifiable causal mechanism for depression. Areas covered: An overview of studies on the interplay between cognitive control and RNT is presented, assessing the potential of training cognitive control in depressed individuals. Cognitive Control Training (CCT), or other techniques aimed at remediating executive functioning, provides an …
