In Nigg's excellent article, he deals with a variety of complex conceptual issues related to the constructs of self-regulation and executive functioning (EF). Overall, I agree that the terminology proposed by Nigg should be adopted; moreover, the conceptual distinctions he provides should help the field to move forward with regard to the understanding of varied constructs related to self-regulation. In the spirit of further clarification, I questioned Nigg's suggestions that (a) working memory should be considered as part of the construct of top-down regulation and (b) planning is a higher level component of EF but not part of effortful control...

Giant prolactinomas, rare in children, can have devastating endocrine, neurological and visual sequelae. Dopamine agonists (DA) are effective first-line therapy with few side-effects at doses usually used for prolactinoma treatment(1) , but higher-dose therapy for Parkinson's disease has well-recognized associations with impulse control disorders (ICD) including pathological gambling, impulsive eating, compulsive shopping and hypersexuality. Such associations are not well recognized with prolactinomas; to our knowledge this is the first reported case of hypersexuality in an adolescent receiving cabergoline for a giant prolactinoma...

BACKGROUND: Novelty-seeking (NS) and impulsive personality traits have been proposed to reflect an interplay between fronto-cortical and limbic systems, including the limbic striatum (LS). Although neuroimaging studies have provided some evidence for this, most are comprised of small samples and many report surprisingly large effects given the challenges of trying to relate a snapshot of brain function or structure to an entity as complex as personality. The current work tested a priori hypotheses about associations between striatal dopamine (DA) release, cortical thickness (CT), and NS in a large sample of healthy adults...

OBJECTIVE To determine whether walking at specific ranges of absolute and relative (V*) velocity would aid efficient capture of gait trial data with low ground reaction force (GRF) variance in a heterogeneous sample of dogs. ANIMALS 17 clinically normal dogs of various breeds, ages, and sexes. PROCEDURES Each dog was walked across a force platform at its preferred velocity, with controlled acceleration within 0.5 m/s(2). Ranges in V* were created for height at the highest point of the shoulders (withers; WHV*)...

Youths with conduct disorders (CD) are particularly studied for their violent and aggressive behaviors. Many researchers considered aggressive behaviors as being either reactive or proactive. Moreover, factors such as age of CD onset, impulsivity, and callous-unemotional traits, separately, have been related to these different types of aggressive behaviors. However, very few studies addressed the combined contribution of these three factors on proactive and reactive aggression. This question was tested in a sample composed of 43 male adolescents with CD...

BACKGROUND: Emotional Intelligence (EI) is a type of social intelligence. Excellent scores are achieved by displaying high levels of empathy in interpersonal relationships, strong skills in managing stressful situations as well as other personal competencies. Many of the social competencies that EI describes may have a direct impact on patient care. The objective of this study was to describe EI of pediatric residents and to identify if there are EI skills that should be selected for targeted intervention...

Nowadays the smartphone plays an important role in our lives. While it brings us convenience and efficiency, its overuse can cause problems. Although a great number of studies have demonstrated that people affected by substance abuse, pathological gambling, and internet addiction disorder have lower self-control than average, scarcely any study has investigated the decision making of smartphone high users by using a behavioral paradigm. The present study employed an intertemporal task, the Smartphone Addiction Inventory (SPAI) and the Barratt Impulsiveness Scale 11th version (BIS-11) to explore the decision control of smartphone high users in a sample of 125 college students...

Daniel Nettle
Recent research has uncovered many examples of socioeconomic gradients in behavior and psychological states. As yet there is no theoretical consensus on the nature of the causal processes that produce these gradients. Here, I present the hunger hypothesis, namely the claim that part of the reason that people of lower socioeconomic position behave and feel as they do is that they are relatively often hungry. The hunger hypothesis applies in particular to impulsivity-hyperactivity, irritability-aggression, anxiety, and persistent narcotic use, all of which have been found to show socioeconomic gradients...

The α2-adrenoceptor antagonist, yohimbine, is commonly used as a pharmacological stressor. Its behavioural effects are typically attributed to elevated noradrenaline release via blockade of central, inhibitory autoreceptors. We have previously reported that yohimbine increases motor impulsivity in rats on the five-choice serial reaction time task (5CSRTT), a cognitive behavioural assessment which measures motor impulsivity and visuospatial attention. Furthermore, this effect depended on cyclic adenomonophosphate (cAMP) signalling via cAMP response element binding (CREB) protein in the orbitofrontal cortex (OFC)...

Antoine Sauvage, Guillaume Hubert, Jonathan Touboul, Jérôme Ribot
Neuronal activation triggers local changes in blood flow and hemoglobin oxygenation. These hemodynamic signals can be recorded through functional magnetic resonance imaging or intrinsic optical imaging, and allows inferring neural activity in response to stimuli. These techniques are widely used to uncover functional brain architectures. However, their accuracy suffers from distortions inherent to hemodynamic responses and noise. The analysis of these signals currently relies on models of impulse hemodynamic responses to brief stimuli...

BACKGROUND: Our objective was to evaluate the accuracy of acoustic radiation force impulse (ARFI) elastography in determining extent of liver fibrosis in pediatric patients with short bowel syndrome (SBS). METHODS: This prospective cohort study included pediatric patients with SBS who underwent ultrasound with ARFI measurements of shear wave speed (SWS) and liver biopsy within 30days of each other between 12/2014-9/2015. The mean and median SWS were compared to the stage of fibrosis...

In 2009, Gao and Raine's meta-analysis analysed P3 modulation over the antisocial spectrum. However, some questions remained open regarding the P3 modulation patterns across impulsive and violent manifestations of antisocial behaviour, phenotypic components of psychopathy, and P3 components. A systematic review of 36 studies was conducted (N=3514) to extend previous results and to address these unresolved questions. A clear link between decreased P3 amplitude and antisocial behaviour was found. In psychopathy, dimensional approaches become more informative than taxonomic models...

BACKGROUND: Tryptophan hydroxylase (TPH) is the rate-limiting enzyme in the synthesis of serotonin. We examined whether the TPH2 polymorphism -703G/T (rs4570625) is associated with aggressiveness and impulsivity, and the prevalence of psychiatric disorders, in a population-representative sample. METHODS: We used self and proxy reports on aggressive behaviour in the younger birth cohort of the longitudinal Estonian Children Personality, Behaviour and Health Study collected at age 25, and earlier collected impulsivity and related data of both ECPBHS cohorts...

OBJECTIVES: We studied the course of lower respiratory symptoms (LRS; cough, wheeze or dyspnoea) among community members exposed to the 9/11/2001 World Trade Center (WTC) attacks during a period of 12-13 years following the attacks, and evaluated risk factors for LRS persistence, including peripheral airway dysfunction and post-traumatic stress disorder (PTSD). METHODS: Non-smoking adult participants in a case-control study of post-9/11-onset LRS (exam 1, 2008-2010) were recruited for follow-up (exam 2, 2013-2014)...

Early life experience profoundly impacts behavior and cognitive functions in rats. The present study investigated how the presence of conspecifics and/or novel objects, could independently influence individual differences in impulsivity and behavioral flexibility. Twenty-four rats were reared in an isolated condition, an isolated condition with a novel object, a pair-housed social condition, or a pair-housed social condition with a novel object. The rats were then tested on an impulsive choice task, a behavioral flexibility task, and an impulsive action task...

Obesity is a significant public health concern that affects more than one-fifth of adolescents aged 12-19 in the United States. Theoretical models suggest that prolonged dietary restraint leads to binge-eating behaviors, which in turn increases individuals' risk for weight gain or obesity. Results from the literature indicate a potential role for negative urgency (the tendency to act rashly when distressed) as a mediating variable that explains the link between dietary restraint and binge-eating episodes. The current study tested short-term, prospective longitudinal associations among dietary restraint, binge eating, negative urgency, and weight gain among college students - a population at increased risk for the development of overweight and obesity...

Stochastic deconvolution is a parameter estimation method that calculates drug absorption using a non-linear mixed effects model in which the random effects associated with absorption represent a Wiener process. The present work compares, 1) stochastic deconvolution, and 2) numerical deconvolution, using clinical pharmacokinetic data generated for an IVIVC study of extended release (ER) formulations of a BCS class III drug substance. The preliminary analysis found that numerical and stochastic deconvolution yielded superimposable fraction absorbed (Fabs) versus time profiles when supplied with exactly the same externally-determined unit impulse response parameters...

Hamed Kouhi, Mansour Kabganian, Farhad Fani Saberi, Morteza Shahravi
In impulsive orbital maneuvers, thrust vector misalignment from the center of mass (C.M) results in a large disturbance torque. In this paper a thrusting maneuver system is proposed and studied which is based on the combination of a one degree of freedom (1DoF) gimbaled-thruster, two reaction wheels (RWs) and spin-stabilization. The main goals are disturbance rejection and thrust vector stabilization without using reaction control systems (RCS). The nonlinear two-body dynamics of the proposed system is formulated...

This paper is concerned with the H∞ control problem for a class of singular systems. The systems under consideration involve state time-varying delay. The aim of this paper is to design a dynamic feedback controller such that the resultant closed-loop system is regular, impulse-free and stable with given H∞ performance index. By using the Lyapunov-Krasovskii functional method, some delay-dependent sufficient criteria which guarantee the existence of the dynamic feedback controller and determine explicitly the parameters of the dynamic feedback controller are presented...
