Impulsivity is often cited as a core dysfunction in those who are high in psychopathic traits. However, both impulsivity and psychopathy are both multi-faceted constructs. We examined a 3-factor model of self-reported impulsivity (Barrett Impulsivity: BIS-11) against the 2-factor and 4-facet model of psychopathy as defined by the Psychopathy Checklist-Revised (PCL-R). Those high on 'secondary p...

BACKGROUND Impulsivity is a key component of the manic behavior of bipolar disorder and is reported to occur in bipolar patients as a stable characteristic, i.e. a trait. Nevertheless, impulsivity has not been widely studied in depressed bipolar patients. We assessed impulsivity in depressed and euthymic bipolar and unipolar patients and healthy controls. We hypothesized that bipolar subjects w...

Introduction The relationship between cyber video game addiction and impulsivity is controversial. Some studies have shown a significant link, others found no association the two behaviours. Objectives To study in adolescents with problematic use of internet games. Methods This was cross-sectional, descriptive analytical study, conducted among sample randomly collected 6 schools region Sfax-Tun...

AIMS To examine the moderating effects of alcohol myopia on cognitive impulsivity in humans using the delay-discounting paradigm. METHODS Seventy-six male undergraduate students were randomly assigned to sober, placebo or alcohol conditions. In the delay-discounting task, participants made a series of hypothetical choices between a small, immediate reward and a large, delayed reward. To test ...

The present study explored the relationship between risky cybersecurity behaviours, attitudes towards cybersecurity in a business environment, Internet addiction, and impulsivity. 538 participants in part-time or full-time employment in the UK completed an online questionnaire, with responses from 515 being used in the data analysis. The survey included an attitude towards cybercrime and cybers...

Barrat Impulsiveness Scale 11 (BIS-11). The BIS-11 is a widely used measure of self-reported impulsivity, with higher scores reflecting greater impulsivity. In addition to an overall measure, the BIS provides three factors assessing different forms of impulsivity. Attentional Impulsivity reflects the difficulty focusing on the task at hand and experiencing racing or intrusive thoughts. Motor Im...

The loudness dependence of the auditory evoked potential [LDAEP] is a measure of brain sensitivity and a potential biological marker of central serotonergic activity. Serotonin was also known to be related with impulsivity. Hence, LDAEP may be useful to evaluate a relationship between sensory sensitivity and impulsivity. As has been reported, LDAEP is related to depression, anxiety and mood lab...

There is a need to better understand the antecedent of aggressive behaviors in order to tailor treatments and reduce the associated damage to the others and the self. Possible mechanisms underlying aggression are poor emotional awareness and emotion dysregulation, as well as impulsivity. Here, we examined the relationships among alexithymia, emotion dysregulation, impulsivity and aggression, co...

BACKGROUND Identifying objective and accurate markers of cocaine dependence (CD) can innovate its prevention and treatment. Existing evidence suggests that CD is characterized by a wide range of cognitive deficits, most notably by increased impulsivity. Impulsivity is multidimensional and it is unclear which of its various dimensions would have the highest predictive utility for CD. The machine...
