“…For example, future studies may explore whether enhancing interoceptive accuracy on the heartbeat discrimination task (via providing feedback based on participant performance) leads to less impulsive behaviors, both self-reported and assessed with laboratorybased tasks. Specifically, since nonplanning impulsivity is known to play a vital role in binge drinking and alcohol use and abuse (Caswell, Celio, Morgan, & Duka, 2015;Hamilton, Sinha, & Potenza, 2012;Jakubczyk et al, 2013), if replicated, these findings bear a great potential for novel therapeutic interventions, which could aid alcohol abuse prevention and treatment.…”

Influential theories concerning personality argue that many impulsive individuals show physiological underarousal at rest. This interoceptive state is proposed to be egodystonic, motivating impulsive maladaptive actions to enhance arousal. However, there is little empirical research on this matter. The current study tested the relationship between physiological markers of arousal, measures of interoceptive (in)sensitivity, and trait impulsivity in a nonclinical sample of young adults. Experiment 1 investigated whether individuals (N = 31) with high trait impulsivity show decreased resting measures of arousal (indexed from heart rate, heart rate variability, and sympathetic electrodermal activity). Experiment 2 assessed whether trait impulsivity is linked to interoceptive abilities (N = 60). Overall, our results do not provide any compelling support for the underarousal theory of impulsivity. However, impaired interoceptive (cardiac discrimination) accuracy predicted the degree of Barratt nonplanning impulsivity, such that individuals with a better ability to distinguish between internal (bodily) and external signals manifest lower levels of nonplanning trait impulsivity. These findings open an avenue for potential novel interventions aimed at improving planning abilities via better interoceptive discrimination.

“…Increased alcohol use and heavy episodic alcohol consumption among college students is tied to elevated impulsivity levels (Cyders et al, 2009;Caswell et al, 2015b). However, impulsivity is a multidimensional construct (Caswell et al, 2015a;Herman et al, 2018), and it is possible that distinct facets of impulsivity may not be disrupted equally in BD.…”

Binge drinking is associated with attenuated frontal and parietal activation during successful response inhibition in fearful context

Binge drinking is associated with increased impulsivity and altered emotional processing. This study investigated, in a group of university students who differed in their level of binge drinking, whether the ability to inhibit a pre-potent response and to delay gratification is disrupted in the presence of emotional context. We further tested whether functional connectivity within intrinsic resting-state networks was associated with alcohol use. Higher incidence of binge drinking was associated with enhanced activation of the lateral occipital cortex, angular gyrus, the left frontal pole during successful response inhibition irrespective of emotional context. This observation suggests a compensatory mechanism. However, higher binge drinking attenuated frontal and parietal activation during successful response inhibition within a fearful context, indicating the selective emotional facilitation of inhibitory control. Similarly, higher binge drinking was associated with attenuated frontopolar activation when choosing a delayed reward over an immediate reward within the fearful, relative to the neutral, context. Resting-state functional data analysis revealed that binge drinking decreased coupling between the right supramarginal gyrus and Ventral Attention Network, indicating alcohol-associated disruption of functional connectivity within brain substrates directing attention. Together, our results suggest that binge drinking makes response inhibition more effortful, yet emotional (more arousing) contexts may mitigate this; disrupted functional connectivity between regions underlying adaptive attentional control, is a likely mechanism underlying these response inhibition effects associated with binge drinking.

“…One personality trait that has been consistently correlated with binge drinking in the literature, especially among college students, is impulsivity (Balodis et al, 2009;Carlson et al, 2010;Caswell, Celio, Morgan, & Duka, 2016;Clark et al, 2012;Townshend, Kambouropoulos, Griffin, Hunt, & Milani, 2014;Wellman, Contreras, Dugas, O'Loughlin, & O'Loughlin, 2014). In the literature, impulsivity is considered a multifaceted concept (as noted in Caswell et al, 2016); however, most commonly impulsivity refers to a deficits in the ability to regulate present actions and plan proactively, or to favouring spontaneous behaviour over regard for future consequences.…”

Abstract:There is a lack of recent research exploring the differences between binge and non-binge drinkers among Canadian university students. The current study aims to address this gap in the literature through an exploratory statistical analysis. Univariate, bivariate, and multivariate (logistic regression) analyses were employed to identify the prevalence of binge drinking, as well as its various sociodemographic, behavioural, and mental health correlates. A large majority (83.1%) of the 507 respondents reported consuming alcohol in the previous 12 months; of these, 69.7% (67.0% of males, 70.9% of females) reported engaging in binge drinking (5 drinks in one session for males, 4 for females) at least once in the previous 30 days. Although there was no significant gender difference in the prevalence of binge drinking, there were several gender differences among the correlates. Compared to non-binge drinkers, male binge drinkers reported greater life satisfaction, and greater probability of smoking cigarettes and engaging in risky sex, while females reported greater impulsivity and lower religiosity. As expected, binge drinkers experienced more adverse consequences from alcohol consumption than did non-binge drinkers, but unexpectedly did not differ significantly in mental health and wellbeing. Limitations of the present study and future research directions are discussed with a view to improving our understanding of risk and protective factors related to unhealthy alcohol consumption among university students in Canada and abroad.Keywords binge drinking; alcohol research; university students; Canada; mental health Tamara Edkins MA is a student in the Faculty of Law at the University of Manitoba, 224 Dysart Rd., Winnipeg, MB R3T 2N2.
