BACKGROUND Pathological forms of impulsivity are manifest in a number of psychiatric disorders listed in DSM-5, including attention-deficit/hyperactivity disorder and substance use disorder. However, the molecular and cellular substrates of impulsivity are poorly understood. Here, we investigated a specific form of motor impulsivity in rats, namely premature responding, on a five-choice serial ...

INTRODUCTION Impulsivity is widely regarded as a risk factor for drug dependence. However, its relationship with the symptomatology of nicotine dependence is poorly understood. METHODS To examine the nature of these relationships, we recruited 404 daily and occasional smokers from a predominantly student population and assessed the association between impulsivity, as measured by the Barratt I...

Acting in accord with long-term goals requires control of interfering impulses, the success of which depends on several different processes. Using a structural-equation modeling approach, we investigated 5 behavioral components of impulsivity: the control of stimulus interference, proactive interference, and response interference, as well as decisional and motivational impulsivity. Results supp...

OBJECTIVE Impulsivity is generally believed to be more characteristic of individuals with bulimic than with restrictive eating disorders (EDs). However, studies have not exhaustively explored the association between EDs and various component dimensions of the impulsivity construct. METHOD We conducted a multidimensional assessment of impulsivity in 84 women with bulimia nervosa (BN), 37 with ...

In the present study we examined, first, whether voluntary and involuntary attention manifest differently in people who differ in impulsivity (measured with the Barratt Impulsivity Scale). For Experiment 1, we used the spatial cueing task with informative and noninformative spatial cues to probe voluntary and involuntary attention, respectively. We found that participants with high impulsivity ...

BACKGROUND Impulsivity is a core feature of borderline personality disorder (BPD). However, previous clinical and experimental studies investigating impulsivity in BPD rendered mixed results. In this study, impulsivity was assessed by self-report scales and behavioral inhibition tasks to compare different data levels. SAMPLING AND METHODS Fifteen women with BPD and 15 matched healthy control ...

The present study (a) tests main and moderational effects of neighborhood and family risk, and adolescent impulsivity on the development of male and female antisocial behavior (ASB) and (b) examines the extent to which these effects work indirectly through parental knowledge. Adolescents (N = 4,597; 51% male) reported on informal social control in their neighborhoods, their family types, and im...

Impulsivity and poor executive control have been implicated in the pathogenesis of many developmental and neuropsychiatric disorders. Similarly, concussions/mild traumatic brain injuries (mTBI) have been associated with increased risk for neuropsychiatric disorders and the development of impulsivity and inattention. Researchers and epidemiologists have therefore considered whether or not concus...
