(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.

O you who believe! Let your slaves and slave-girls, and those among you who have not come to the age of puberty ask your permission on three occasions: before the Fajr prayer, and while you put off your clothes during the afternoon, and after the 'Isha' prayer. (These) three (times) are of privacy for you; other than these times there is no sin on you or on them to move about, attending to each other. Thus Allah makes clear the Ayat to you.

This study draws on Finkel and Eckhardt's (2013) I³ framework to examine the interactive effects of 2 emotion regulation strategies-anger rumination (an impellance factor) and reappraisal (an inhibition factor), and alcohol intoxication (a disinhibition factor)-on intimate partner aggression (IPA) perpetration as measured with an analogue aggression task. Participants were 69 couples recruited from a large Midwestern university (total N = 138). Participants' trait rumination and reappraisal were measured by self-report. Participants were randomized individually to an alcohol or placebo condition, then recalled an anger event while using 1 of 3 randomly assigned emotion regulation conditions (rumination, reappraisal, or uninstructed). Following this, participants completed an analogue aggression task involving ostensibly assigning white noise blasts to their partner. Participants in the a…

Comparing two psychological interventions in reducing impulsive processes of eating behaviour: effects on self-selected portion size.
Objective: Palatable food, such as sweets, contains properties that automatically trigger the impulse to consume it even when people have goals or intentions to refrain from consuming such food. We compared the effectiveness of two interventions in reducing the portion size of palatable food that people select for themselves. Specifically, the use of dieting implementation intentions that reduce behaviour towards palatable food via top-down implementation of a dieting goal was pitted against a stop-signal training that changes the impulse-evoking quality of palatable food from bottom-up.
Design: We compared the two interventions using a 2 × 2 factorial design.
Methods: Participants completed a stop-signal training in which they learned to withhold a behavioural response upon presentation of tempting sweets (vs. control condition) and formed implementation intentions to diet (vs. control …

The influence of Oxytocin on automatic motor simulation.
Motor simulation is important for imitation, action understanding, and a wide range of social cognitive skills. Furthermore, the neuropeptide hormone Oxytocin (OT) has also been related to social information processing in humans, improving perception of social stimuli and increasing altruism and trust. Surprisingly, however, a direct link between OT and motor simulation has never been systematically investigated. The current study examined this question using the imitation-inhibition task, a paradigm used to investigate automatic imitation behaviour and motor simulation. In this task, participants carry out simple finger movements while observing irrelevant movements that either match (congruent condition) or do not match (incongruent condition) the instructed movements. In a double-blind, placebo-controlled design, male participants were administered either OT (N=24) or placebo (N=24), …

Increasing self-regulatory energy using an Internet-based training application delivered by smartphone technology.
Self-control resources can be defined in terms of "energy." Repeated attempts to override desires and impulses can result in a state of reduced self-control energy termed "ego depletion" leading to a reduced capacity to regulate future self-control behaviors effectively. Regular practice or "training" on self-control tasks may improve an individual's capacity to overcome ego depletion effectively. The current research tested the effectiveness of training using a novel Internet-based smartphone application to improve self-control and reduce ego depletion. In two experiments, participants were randomly assigned to either an experimental group, which received a daily program of self-control training using a modified Stroop-task Internet-based application delivered via smartphone to participants over a 4-week period, or a no-training control group. Participants assigned to the experimental g…

Post-traumatic stress disorder and the outcome of dialectical behaviour therapy for borderline personality disorder.
Background: Individuals with borderline personality disorder (BPD) and comorbid post-traumatic stress disorder (PTSD) have a worse prognosis than individuals with BPD alone. A common view is that the emotional instability and impulsivity of BPD should be treated before attempting to address trauma. However, PTSD symptoms may interfere with patients' ability to benefit from such 'stabilizing' treatments.
Methods: The effect of BPD-PTSD comorbidity on self-harm and BPD symptom outcomes was evaluated in 89 patients receiving dialectical behaviour therapy, using multilevel modelling.
Results: Patients with comorbid BPD-PTSD showed a trend towards elevated BPD symptoms throughout the treatment year (β = 2.12, 95% CI = -0.21-4.44, p = 0.07). There was a three-way interaction between PTSD comorbidity, treatment completion and time, whereby PTSD comorbidity was associated with less reduction in …

A double-blind, placebo-controlled trial of topiramate for pathological gambling.
Objectives: Pathological gambling (PG) is an impulse control disorder characterized by recurrent gambling thoughts and behaviours that impair social functioning. Earlier studies suggested that topiramate may be effective in treating some impulse control disorders. We conducted the first randomized, controlled trial of topiramate in PG.
Methods: PG patients were randomized to topiramate (N = 20) or placebo (N = 22) in this 14-week, double-blind, placebo-controlled, parallel-group trial. The primary outcome measure was change in the obsessions subscale of the Yale-Brown Obsessive-Compulsive Scale Modified for Pathological Gambling.
Results: Mixed regression models (time [weeks] × treatment) revealed no significant treatment effect of topiramate on the primary or secondary outcome measures. The most statistically robust findings involved reducing the Barratt Impulsiveness Scale (BIS) total …

Factors related to dropout from treatment in two outpatient treatments for borderline personality disorder.
Patients with borderline personality disorder frequently drop out prematurely from psychotherapy. This study examined factors related to treatment attrition in 180 patients enrolled in a randomized controlled trial comparing 1 year of Dialectical Behavior Therapy (DBT) to General Psychiatric Management (GPM). Completers and dropouts were compared on a range of variables, including demographics, Axis I and Axis II disorders, anger and impulsivity, therapeutic alliance, and treatment condition. The participants were on average 30.36 years old and 86% were female. Regression analyses revealed that individuals who dropped out had higher levels of anger (p = .01), greater Axis I comorbidity (p = .03), poorer therapeutic alliance (p = .003), and a higher number of lifetime suicide attempts (p = .05). An interaction was also found between Axis I comorbidity and treatment condition, with signifi…

Neural and behavioral mechanisms of impulsive choice in alcohol use disorder.
Background: Alcohol dependence has repeatedly been associated with impulsive choice, or the inability to choose large delayed rewards over smaller, but more immediate rewards. However, the neural basis of impulsive choice in alcohol use disorders (AUDs) is not well understood.
Methods: One hundred fifty-one individuals with a range of alcohol use from social drinking to severe alcohol dependence completed a delay discounting task while undergoing functional magnetic resonance imaging. Participants received customized trials designed to ensure an approximately equivalent number of immediate responses.
Results: Delaying gratification recruited regions involved in cognitive control, conflict monitoring, and the interpretation of somatic states. Individuals with more severe alcohol use problems showed increased discounting of delayed rewards and greater activation in several regions includin…

Preschool boys' development of emotional self-regulation strategies in a sample at risk for behavior problems.
Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys' emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away f…

The role of negative affectivity and social inhibition in perceiving social threat: an fMRI study.
Personality is associated with specific emotion regulation styles presumably linked with unique brain activity patterns. By using functional magnetic resonance imaging (fMRI) in 26 individuals, the neural responses to threatening (fearful and angry) facial and bodily expressions were investigated in relation to negative affectivity and social inhibition. A negative correlation was observed between negative affectivity and activation of the amygdala, fusiform gyrus, insula and hippocampus. Increased activation following threatening stimuli was observed in the left temporo-parietal junction and right extrastriate body area correlating with more social inhibition traits. Interestingly, the orbitofrontal cortex, superior temporal sulcus, inferior frontal gyrus (Brodmann area 45) and temporal pole correlated negatively with negative affectivity and positively with social inhibition. Whereas i…

Impulsive choice and altruistic punishment are correlated and increase in tandem with serotonin depletion.
Human cooperation may partly depend on the presence of individuals willing to incur personal costs to punish noncooperators. The psychological factors that motivate such 'altruistic punishment' are not fully understood; some have argued that altruistic punishment is a deliberate act of norm enforcement that requires self-control, while others claim that it is an impulsive act driven primarily by emotion. In the current study, we addressed this question by examining the relationship between impulsive choice and altruistic punishment in the ultimatum game. As the neurotransmitter serotonin has been implicated in both impulsive choice and altruistic punishment, we investigated the effects of manipulating serotonin on both measures. Across individuals, impulsive choice and altruistic punishment were correlated and increased following serotonin depletion. These findings imply that altruistic …

This study examined putative subtypes of pathological gamblers (PGs) based on the Pathways model, and it also evaluated whether the subtypes would benefit differentially from treatment. Treatment-seeking PGs (N = 229) were categorized into Pathways subtypes based on scores from questionnaires assessing anxiety, depression, and impulsivity. The Addiction Severity Index-Gambling assessed severity of gambling problems at baseline, posttreatment, and 12-month follow-up. Compared with behaviorally conditioned (BC) gamblers, emotionally vulnerable (EV) gamblers had higher psychiatric and gambling severity, and were more likely to have a parent with a psychiatric history. Antisocial impulsive (AI) gamblers also had elevated gambling and psychiatric severity relative to BC gamblers. They were more likely to have antisocial personality disorder and had the highest legal and family/social severity…

Stokes C, Hirsch CR (2010)randomised controlled trialMEDLINE-indexed journal, not yet read by usBehaviour research and therapy43 citations Engaging in imagery versus verbal processing of worry: Impact on negative intrusions in high worriers.
Chronic, excessive, and uncontrollable worry is the defining characteristic of generalised anxiety disorder. Worry largely consists of verbal thought and it has been postulated that this predominance of verbal thought in worry may contribute to its perseveration. In an investigation of this issue, high worriers were trained to engage in either imagery or verbal processing. Mentation was sampled before and after a five-minute period of worry during which participants engaged in either imagery of the worry topic or verbal processing of the worry topic. Verbal worry resulted in a significant increase in negative intrusions, consistent with previous research. Furthermore, imagery was associated with a decrease in negative intrusions. The results support the theory that the predominantly verbal nature of worry may be responsible for the uncontrollability and maintenance of worry.

The Yale-Brown-Cornell eating disorder scale in women with anorexia nervosa: what is it measuring?
Objective: The Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS) assesses eating disorder preoccupations, rituals, and symptom severity. This study examines the YBC-EDS in relation to eating disorder psychopathology, obsessionality, and impulsivity variables in women with anorexia nervosa (AN) and sensitivity of the YBC-EDS to change after psychotherapy.
Method: Participants were 56 women with "spectrum" AN (14.5 < BMI < 19). Variables examined in relation to the YBC-EDS were as follows: eating pathology, obsessionality (obsessive compulsive disorder and personality diagnoses, perfectionism), and impulsivity (borderline personality, impulsive traits, and behaviors). YBC-EDS scores were examined pre- and post-treatment.
Results: Eating Disorder Examination scores most strongly predicted the YBC-EDS. As expected, perfectionism was significantly associated, but so was impulsivity. YBC-EDS …

Background: This study examined the effect of Delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on brain activation during a motor inhibition task.
Methods: Functional magnetic resonance imaging and behavioural measures were recorded while 15 healthy volunteers performed a Go/No-Go task following administration of either THC or CBD or placebo in a double-blind, pseudo-randomized, placebo-controlled repeated measures within-subject design.
Results: Relative to placebo, THC attenuated activation in the right inferior frontal and the anterior cingulate gyrus. In contrast, CBD deactivated the left temporal cortex and insula. These effects were not related to changes in anxiety, intoxication, sedation, and psychotic symptoms.
Conclusions: These data suggest that THC attenuates the engagement of brain regions that mediate response inhibition. CBD modulated function in regions not usuall…

Serum omega-3 fatty acids are associated with variation in mood, personality and behavior in hypercholesterolemic community volunteers.
Low dietary intake of omega-3 polyunsaturated fatty acids has been linked to several features of psychiatric symptomatology, including depression, disorders of impulse control, and hostility. Preliminary intervention trials of omega-3 fatty acid supplementation for clinical depression and other disorders have reported benefit. However, few studies have investigated the relationships between these fatty acids and normative variability in mood, behavior and personality. Participants were 105 hypercholesterolemic, but otherwise healthy, non-smoking adults. Fasting serum alpha-linolenic (alpha-LNA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) were assayed with gas chromatography. Participants completed the Beck Depression Inventory (BDI), the NEO Five Factor Personality Inventory (NEO-FFI) and the Barratt Impulsiveness Scale (BIS).

Self-control relies on glucose as a limited energy source: willpower is more than a metaphor.
The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.

Sustained efficacy of dialectical behaviour therapy for borderline personality disorder.
Dialectical Behaviour Therapy (DBT) is considered one of the most promising treatments for borderline personality disorder (BPD). Recently, we reported significantly positive effects of 12 months DBT on parasuicidal behaviour and impulsivity in a mixed group of female BPD patients with and without substance abuse. Fifty-eight women with BPD were randomly assigned to either 52 weeks of DBT or treatment as usual (TAU). Follow-up assessment took place at 78 weeks, i.e., 6 months after discontinuation of DBT. Participants were clinical referrals from addiction treatment and psychiatric services. Outcome measures included parasuicidal behaviour, impulsivity and substance abuse. Six months after treatment discontinuation, the benefits of DBT over TAU in terms of lower levels of parasuicidal and impulsive behaviours, and in alcohol use, sustained. No differences between the treatment conditions…

The Interaction Between Measurement and Individual Difference in Ego Depletion: Task Type, Trait Self-Control and Action Orientation.
Previous research found that performing an initial self-control task impairs subsequent self-control performance, which is referred to as ego depletion. However, recent meta-analyses and replication studies have led to controversies over whether the ego depletion effect is as reliable as previously assumed. The present study aimed to shed more light on these controversies by combining depletion measurement task type and personality as moderators. Study 1 investigated trait self-control and action orientation's moderation role for depletion effects on stop-signal task (inhibitory control). Study 2 examined the trait self-control and action orientation's moderation role for depletion effects on a majority congruent Stroop task (goal maintenance). Results showed that trait self-control moderated the ego depletion effect on stop-signal reaction time (SSRT). High trait self-control people wer…

Acceptance versus reappraisal: Behavioral, autonomic, and neural effects.
Emotion regulation (ER) is an important skill for well-being. Cognitive reappraisal is a goal-oriented cognitive change strategy. Acceptance involves decentering from immediate habits of reactivity, observing moment-to-moment shifts in thoughts, emotions, and sensations. These two regulation strategies are thought to have different effects on emotion; however, no study has examined the differential effects of reappraisal and acceptance on behavioral, autonomic, and brain responses in the context of ideographic personally salient negative self-beliefs. Thirty-five right-handed, healthy adults were presented idiographic negative self-beliefs embedded in autobiographical scripts. We measured negative emotion ratings, autonomic psychophysiology, and functional magnetic resonance imaging blood oxygen-level dependent responses while participants read neutral statements, reacted to their own ne…

Aging ebbs the flow of thought: adult age differences in mind wandering, executive control, and self-evaluation.
Two experiments examined the relations among adult aging, mind wandering, and executive-task performance, following from surprising laboratory findings that older adults report fewer task-unrelated thoughts (TUTs) than do younger adults (e.g., Giambra, 1989; Jackson & Balota, 2012). Because older adults may experience more ability- and performance-related worry during cognitive tasks in the laboratory, and because these evaluative thoughts (known as task-related interference, "TRI") might be sometimes misclassified by subjects as task-related, we asked subjects to distinguish task-related thoughts from TRI and TUTs when probed during ongoing tasks. In Experiment 1, younger and older adults completed either a go/no-go or a vigilance version of a sustained attention to response task (SART). Older adults reported more TRI and fewer TUTs than did younger adults while also performing more acc…

Functional Neuroanatomy of Emotion and Its Regulation in PTSD.
Posttraumatic stress disorder (PTSD) is a devastating disorder, linked to profound mental, physical, occupational, and functional impairment. In addition, it is a highly complex disorder, characterized by symptom heterogeneity across multiple domains. Nevertheless, emotion dysregulation arising from the exaggerated response to threat or from the inability to regulate negative emotional states plays a defining role in the pathophysiology of PTSD. In order to improve our understanding of how emotion dysregulation manifests in this illness, functional neuroimaging research over the past 20 years provides great insight into underlying neuroanatomy of each component of emotion dysregulation in the context of PTSD. While prior reviews exist on the topic of neuroimaging findings in PTSD, the present review synthesizes that work through the lens of emotion and its regulation. Studies that employ…

Denson TF (2013)reviewMEDLINE-indexed journal, not yet read by usPersonality and social psychology review : an official journal of the Society for Personality and Social Psychology, Inc67 citations The multiple systems model of angry rumination.
Angry rumination is perseverative thinking about a personally meaningful anger-inducing event and is a risk factor for aggression. This article presents a new model for understanding angry rumination across five levels of analysis: cognitive, neurobiological, affective, executive control, and behavioral. The type of rumination that occurs at the cognitive level moderates affective responding and neurobiological activation, which influences executive control and aggression. Angry rumination recruits brain regions implicated in cognitive control, emotion regulation, negative affect, physiological arousal, social cognition, and self-reflection on emotional states. Moreover, angry rumination temporarily reduces self-control, which can increase aggression. The article suggests a functional account of angry rumination, identifies gaps in our knowledge, and proposes future research directions b…
