(O ye who believe! Let your slaves, and those of you who have not come to puberty, ask leave of you�) [24:58]. Said ibn �Abbas: �The Messenger of Allah, Allah bless him and give him peace, sent a boy from the Helpers, called Mudlij ibn �Amr, to �Umar ibn al-Khattab, May Allah be pleased with him, after noon to summon him. When he entered in, he saw �Umar in a state which the latter disliked to be seen in. And so he said to the Prophet: �O Messenger of Allah, I wish that Allah, exalted is He, give us some commands and prohibitions regarding asking permission before entering�. And so Allah, exalted is He, revealed this verse�. Said Muqatil: �This verse was revealed about Asma� bint Marthid. She had a slave-boy who was quite old and he happened to enter in on her one day at a time in which she disliked him to enter in on her.

401 to 425 of 1,075Emotion regulation in binge eating disorder.
A review of the literature on emotion regulation in binge eating disorder (BED) published both in English and Polish between 1990 and 2020. BED might be considered as an impulsive and compulsive disorder associated with altered reward sensitivity and food-related attentional bias. The growing body of research indicated that there were corticostriatal circuitry alterations in BED, comparable to those observed in substance abuse, including altered function of orbitofrontal, prefrontal and insular cortices with the striatum included. Negative emotions and deficits in their regulation play a significant role in BED. Processing of anger, anxiety and sadness appear to be particularly important in this disorder. Research results identified an increase in negative emotions preceding episodes of binge eating. However, there is still inconsistency when it comes to whether these episodes alleviate …

Appetite self-regulation declines across childhood while general self-regulation improves: A narrative review of the origins and development of appetite self-regulation.
This narrative review discusses the origins and development of appetite self-regulation (ASR) in childhood (from infancy to age 6 or 7 years). The origins, or foundations, are the biological infrastructure associated with appetite regulation and appetite self-regulation. Homeostatic regulation in infancy is examined and then evidence about developmental change in components of ASR. The main ASR-related components covered are: delay-of-gratification, caloric compensation, eating in the absence of hunger, food responsiveness/hedonics and fussy eating. The research included behavioral measures, parent-reports of appetitive traits and fMRI studies. There were two main trends in the evidence: a decline across childhood in the components of ASR associated with food approach (and therefore an increase in disinhibited eating), and wide individual differences. The decline in ASR contrasts with ge…

A Life Span Perspective on Borderline Personality Disorder.
Purpose of review: To provide an update of a life span perspective on borderline personality disorder (BPD). We address the life span course of BPD, and discuss possible implications for assessment, treatment, and research.
Recent findings: BPD first manifests itself in adolescence and can be distinguished reliably from normal adolescent development. The course of BPD from adolescence to late life is characterized by a symptomatic switch from affective dysregulation, impulsivity, and suicidality to maladaptive interpersonal functioning and enduring functional impairments, with subsequent remission and relapse. Dimensional models of BPD appear more age neutral and more useful across the entire life span. There is a need for age-specific interventions across the life span. BPD symptoms and impairments tend to wax and wane from adolescence up to old age, and presentation depends on contextu…

Impulse control disorders (ICDs) and related impulsive and compulsive behaviors (together called ICBs) have been increasingly recognized in the context of Parkinson's disease (PD) and treatment. The International Parkinson's and Movement Disorder Society commissioned a task force to assess available clinical screening instruments and rating scales, including their clinimetric properties, make recommendations regarding their utility, and suggest future directions in scale development and validation. The literature was systematically searched for scales measuring a range of reported ICBs in PD. A scale was designated "recommended" if the scale had been employed in PD studies, been used beyond the group that developed it, and had adequate clinimetric data published for PD. Numerous diagnostic screening tools and severity rating scales were identified for a range of ICBs, including compulsiv…

Zacks S, Hen M (2018)reviewMEDLINE-indexed journal, not yet read by usJournal of prevention & intervention in the community27 citations Academic interventions for academic procrastination: A review of the literature.
Procrastination is a widespread phenomenon in academic settings. It has been studied from many different theoretical angles, and a variety of causes and consequences have been suggested. Recent studies support the notion that academic procrastination can be seen from a situational perspective and as a failure in learning self-regulation. It suggests that interventions should address situational as well as deficits in self-regulation to help students overcome their procrastinating tendencies. The present review examined the recent literature on causes and consequences of academic procrastination and the limited number of studies of academic interventions for academic procrastination. Findings of this review strengthen the need to further study the topic of academic interventions for academic procrastination and to develop effective interventions.

Roelofs K (2017)reviewMEDLINE-indexed journal, not yet read by usPhilosophical transactions of the Royal Society of London. Series B, Biological sciences309 citations Freeze for action: neurobiological mechanisms in animal and human freezing.
Upon increasing levels of threat, animals activate qualitatively different defensive modes, including freezing and active fight-or-flight reactions. Whereas freezing is a form of behavioural inhibition accompanied by parasympathetically dominated heart rate deceleration, fight-or-flight reactions are associated with sympathetically driven heart rate acceleration. Despite the potential relevance of freezing for human stress-coping, its phenomenology and neurobiological underpinnings remain largely unexplored in humans. Studies in rodents have shown that freezing depends on amygdala projections to the brainstem (periaqueductal grey). Recent neuroimaging studies in humans have indicated that similar brain regions may be involved in human freezing. In addition, flexibly shifting between freezing and active defensive modes is critical for adequate stress-coping and relies on fronto-amygdala c…

Neurofeedback is a psychophysiological procedure in which online feedback of neural activation is provided to the participant for the purpose of self-regulation. Learning control over specific neural substrates has been shown to change specific behaviours. As a progenitor of brain-machine interfaces, neurofeedback has provided a novel way to investigate brain function and neuroplasticity. In this Review, we examine the mechanisms underlying neurofeedback, which have started to be uncovered. We also discuss how neurofeedback is being used in novel experimental and clinical paradigms from a multidisciplinary perspective, encompassing neuroscientific, neuroengineering and learning-science viewpoints.

Reconsidering Emotion Dysregulation.
This article aims to review the concept of emotion dysregulation, focusing on issues related to its definition, meanings and role in psychiatric disorders. Articles on emotion dysregulation published until May 2016 were identified through electronic database searches. Although there is no agreement about the definition of emotion dysregulation, the following five overlapping, not mutually exclusive dimensions of emotion dysregulation were identified: decreased emotional awareness, inadequate emotional reactivity, intense experience and expression of emotions, emotional rigidity and cognitive reappraisal difficulty. These dimensions characterise a number of psychiatric disorders in various proportions, with borderline personality disorder and eating disorders seemingly more affected than other conditions. The present review contributes to the literature by identifying the key components o…

Selection and implementation of emotion regulation strategies in major depressive disorder: An integrative review.
Emotion regulation (ER), broadly defined, has been implicated in mental health, including major depressive disorder (MDD). We review empirical studies examining selection and implementation of ER strategies in adults with current or past MDD. We focus on eight strategies (rumination, distraction, cognitive reappraisal, suppression, acceptance, savoring, positive rumination, dampening), organizing the review by research design: (1) self-reported habitual use (i.e., trait) of ER strategies, (2) spontaneous use of ER strategies in laboratory settings, (3) experimentally instructed ER strategies, and (4) use of ER strategies in naturalistic settings. Reviewed findings suggest that MDD is associated with unskillful selection of ER strategies-indexed by self-reported habitual use of ER strategies-but not impaired abilities to implement them; in fact, those with current MDD and MDD in remission…

Examining emotion regulation in depression: A review and future directions.
Major Depressive Disorder (MDD) is an affective disorder with sustained negative affect and difficulties experiencing positive affect as its hallmark features. Previous work also highlights cognitive biases and deficits in cognitive control that accompany depression and suggestions have been made as to how cognitive and affective aspects of the disorder are linked. Recent work proposes that difficulties in the self-regulation of affect after experiencing negative life events may contribute to risk for the onset of depression, and indeed there is evidence that depressed patients exhibit more frequent use of maladaptive strategies when regulating affect and show difficulties effectively implementing adaptive strategies. Cognitive aspects of depression may play an important role in helping us understand these difficulties in self-regulation. This article reviews recent work on emotion regul…

The dual systems model: Review, reappraisal, and reaffirmation.
According to the dual systems perspective, risk taking peaks during adolescence because activation of an early-maturing socioemotional-incentive processing system amplifies adolescents' affinity for exciting, pleasurable, and novel activities at a time when a still immature cognitive control system is not yet strong enough to consistently restrain potentially hazardous impulses. We review evidence from both the psychological and neuroimaging literatures that has emerged since 2008, when this perspective was originally articulated. Although there are occasional exceptions to the general trends, studies show that, as predicted, psychological and neural manifestations of reward sensitivity increase between childhood and adolescence, peak sometime during the late teen years, and decline thereafter, whereas psychological and neural reflections of better cognitive control increase gradually an…

Neural Circuitry of Impaired Emotion Regulation in Substance Use Disorders.
Impaired emotion regulation contributes to the development and severity of substance use disorders (substance disorders). This review summarizes the literature on alterations in emotion regulation neural circuitry in substance disorders, particularly in relation to disorders of negative affect (without substance disorder), and it presents promising areas of future research. Emotion regulation paradigms during functional magnetic resonance imaging are conceptualized into four dimensions: affect intensity and reactivity, affective modulation, cognitive modulation, and behavioral control. The neural circuitry associated with impaired emotion regulation is compared in individuals with and without substance disorders, with a focus on amygdala, insula, and prefrontal cortex activation and their functional and structural connectivity. Hypoactivation of the rostral anterior cingulate cortex/vent…

Blair RJ (2016)reviewMEDLINE-indexed journal, not yet read by usJournal of child and adolescent psychopharmacology143 citations The Neurobiology of Impulsive Aggression.
This selective review provides a model of the neurobiology of impulsive aggression from a cognitive neuroscience perspective. It is argued that prototypical cases of impulsive aggression, those associated with anger, involve the recruitment of the acute threat response system structures; that is, the amygdala, hypothalamus, and periaqueductal gray. It is argued that whether the recruitment of these structures results in impulsive aggression or not reflects the functional roles of ventromedial frontal cortex and dorsomedial frontal and anterior insula cortex in response selection. It is also argued that impulsive aggression may occur because of impaired decision making. The aggression may not be accompanied by anger, but it will reflect disrupted evaluation of the rewards/benefits of the action.

Brumariu LE (2015)reviewMEDLINE-indexed journal, not yet read by usNew directions for child and adolescent development116 citations Parent-Child Attachment and Emotion Regulation.
Given the centrality of both parent-child attachment and emotion regulation in children's development and adjustment, it is important to evaluate the relations between these constructs. This article discusses conceptual and empirical links between attachment and emotion regulation in middle childhood, highlights progress and challenges in the literature, and outlines future inquiries. Studies have established that securely attached children internalize effective emotion regulation strategies within the attachment relationship and are able to successfully employ adaptive emotion regulation strategies outside the attachment relationship, when the attachment figure is not present. There are not enough studies to conclude yet that the insecure attachment patterns (ambivalent, avoidant, and disorganized) may relate differentially with emotion regulation processes. Studies investigating whethe…

Casey BJ (2015)reviewMEDLINE-indexed journal, not yet read by usAnnual review of psychology461 citations Beyond simple models of self-control to circuit-based accounts of adolescent behavior.
Adolescence is the transition from childhood to adulthood that begins around the onset of puberty and ends with relative independence from the parent. This developmental period is one when an individual is probably stronger, of higher reasoning capacity, and more resistant to disease than ever before, yet when mortality rates increase by 200%. These untimely deaths are not due to disease but to preventable deaths associated with adolescents putting themselves in harm's way (e.g., accidental fatalities). We present evidence that these alarming health statistics are in part due to diminished self-control--the ability to inhibit inappropriate desires, emotions, and actions in favor of appropriate ones. Findings of adolescent-specific changes in self-control and underlying brain circuitry are considered in terms of how evolutionarily based biological constraints and experiences shape the bra…

Positive interventions: An emotion regulation perspective.
The rapid growth of the literature on positive interventions to increase "happiness" has suggested the need for an overarching conceptual framework to integrate the many and apparently disparate findings. In this review, we used the process model of emotion regulation (Gross, 1998) to organize the existing literature on positive interventions and to advance theory by clarifying the mechanisms underlying their effectiveness. We have proposed that positive emotions can be increased both in the short- and longer-term through 5 families of emotion regulation strategies (i.e., situation selection, situation modification, attentional deployment, cognitive change, and response modulation), showing how these emotion regulation strategies can be applied before, during, and after positive emotional events. Regarding short-term increases in positive emotions, our review found that attentional deplo…

Dimensions of emotion dysregulation in anorexia nervosa and bulimia nervosa: A conceptual review of the empirical literature.
Several existing conceptual models and psychological interventions address or emphasize the role of emotion dysregulation in eating disorders. The current article uses Gratz and Roemer's (2004) multidimensional model of emotion regulation and dysregulation as a clinically relevant framework to review the extant literature on emotion dysregulation in anorexia nervosa (AN) and bulimia nervosa (BN). Specifically, the dimensions reviewed include: (1) the flexible use of adaptive and situationally appropriate strategies to modulate the duration and/or intensity of emotional responses, (2) the ability to successfully inhibit impulsive behavior and maintain goal-directed behavior in the context of emotional distress, (3) awareness, clarity, and acceptance of emotional states, and (4) the willingness to experience emotional distress in the pursuit of meaningful activities.

This article reviews central nervous system substrates and autonomic correlates of emotion dysregulation and offers several suggestions for future research. Studies conducted in the last two decades indicate that effective emotion regulation requires efficient top-down, cortically mediated regulation of bottom-up, subcortically mediated individual differences in trait impulsivity and trait anxiety. Without making critical distinctions between highly heritable individual differences in trait impulsivity and trait anxiety, versus less heritable and more socialized deficiencies in emotion regulation, progress in understanding the development of psychopathology among children and adolescents will be hampered. Future research can also be improved by measuring emotion dysregulation across multiple level of analysis, specifying physiological mechanisms through which operant reinforcement shapes…

A dual-systems perspective on addiction: contributions from neuroimaging and cognitive training.
Dual-systems theories explain lapses in self-control in terms of a conflict between automatic and deliberative modes of behavioral control. Numerous studies have now tested whether the brain areas that control behavior are organized in a manner consistent with dual-systems models. Brain regions directly associated with the mesolimbic dopamine system, the nucleus accumbens and ventromedial prefrontal cortex in particular, capture some of the features assumed by automatic processing. Regions in the lateral prefrontal cortex are more closely linked to deliberative processing and the exertion of self-control in the suppression of impulses. While identifying these regions crudely supports dual-systems theories, important modifications to what constitutes automatic and deliberative behavioral control are also suggested. Experiments have identified various means by which automatic processes may…

Phenomenology and treatment of behavioural addictions.
Behavioural addictions are characterized by an inability to resist an urge or drive resulting in actions that are harmful to oneself or others. Behavioural addictions share characteristics with substance and alcohol abuse, and in areas such as natural history, phenomenology, and adverse consequences. Behavioural addictions include pathological gambling, kleptomania, pyromania, compulsive buying, compulsive sexual behaviour, Internet addiction, and binge eating disorder. Few studies have examined the efficacy of pharmacological and psychological treatment for the various behavioural addictions, and therefore, currently, no treatment recommendations can be made.

Martel MM (2013)reviewMEDLINE-indexed journal, not yet read by usPsychological bulletin190 citations Sexual selection and sex differences in the prevalence of childhood externalizing and adolescent internalizing disorders.
Despite the well-established sex difference in prevalence of many childhood and adolescent psychopathological conditions, no integrative metatheory of sex differences in psychopathology exists. This review attempts to provide a metatheoretical framework to guide empirical examination of sex differences in prevalence of childhood-onset "externalizing" and adolescent-onset "internalizing" disorders, based on sexual selection evolutionary theory. Sexual selection theory suggests important between-sex differences in markers, mechanisms, etiology, and developmental timing of risk and resilience relevant to psychopathology. Namely, sexual selection theory hypothesizes that disinhibition and sensation-seeking may be important proximate risk markers for childhood-onset externalizing disorders in males. The theory suggests that these male-biased markers may be a product of their higher exposure t…

The role of impulsivity in relapse vulnerability.
Drug dependence in humans is often accompanied by behavioral disturbances such as maladaptive levels of impulsivity. In turn, there is accumulating evidence from preclinical laboratory animal and clinical studies indicating that impulsive behavior might be causally linked to several distinct processes in drug addiction, including the onset, maintenance and relapsing nature of drug use. This leads to the question as to whether pharmacological or behavioral approaches aimed at ameliorating impulsivity might prove effective therapeutic interventions in human drug dependence. This paper reviews evidence for an important role of impulsivity as a determinant of drug dependence with a particular focus on relapse vulnerability and addresses the implications of these findings for the clinical management of relapse prevention.

Excessive discounting of delayed reinforcers as a trans-disease process contributing to addiction and other disease-related vulnerabilities: emerging evidence.
Delay discounting describes the devaluation of a reinforcer as a function of the delay until its receipt. Although all people discount delayed reinforcers, one consistent finding is that substance-dependent individuals tend to discount delayed reinforcers more rapidly than do healthy controls. Moreover, these higher-than-normal discounting rates have been observed in individuals with other behavioral maladies such as pathological gambling, poor health behavior, and overeating. This suggests that high rates of delay discounting may be a trans-disease process (i.e., a process that occurs across a range of disorders, making findings from one disorder relevant to other disorders). In this paper, we argue that delay discounting is a trans-disease process, undergirded by an imbalance between two competing neurobehavioral decision systems. Implications for our understanding of, and treatment fo…

The role of serotonin in the regulation of patience and impulsivity.
Classic theories suggest that central serotonergic neurons are involved in the behavioral inhibition that is associated with the prediction of negative rewards or punishment. Failed behavioral inhibition can cause impulsive behaviors. However, the behavioral inhibition that results from predicting punishment is not sufficient to explain some forms of impulsive behavior. In this article, we propose that the forebrain serotonergic system is involved in "waiting to avoid punishment" for future punishments and "waiting to obtain reward" for future rewards. Recently, we have found that serotonergic neurons increase their tonic firing rate when rats await food and water rewards and conditioned reinforcer tones. The rate of tonic firing during the delay period was significantly higher when rats were waiting for rewards than for tones, and rats were unable to wait as long for tones as for reward…
