“…While impulsivity is well known to be a multi-dimensional construct, understanding the relative contribution of each subscale is considered critical (Stanford et al, 2009). Several studies suggested that the different sub-domains of impulsivity may be associated with different biological substrates in genetic (Khadka et al, 2014) as well as electrophysiological studies (Kam et al, 2012). Non-planning impulsivity sub-score was specifically associated with some laboratory measures of impulsivity or cognitive executive functions (Stanford et al, 2009;Swann et al, 2002).…”

“…We studied well-motivated undergraduate students, and those in the high impulsive group might have realized their inherent problems with accurate responding, and might have slowed down their responses in order to keep off erroneous key-presses and to maintain adequate performance. Kam et al (2012) also emphasized the possibility of mobilizing extra resources to compensate for cognitive problems related to trait impulsivity in laboratory settings. Nevertheless, in the absence of between-group differences in ERP amplitudes, and without any other external assessment of impulsivity and self-monitoring (e.g., other neuropsychological tests, questionnaires measuring everyday risk-taking behavior), the latter interpretation remains speculative.…”

“…At the same time, the latency of P3 has been shown to be unaffected in impulsive participants (Russo et al, 2008). The BIS subscales scores differentially predicted N2 and P3 measures in a modified continuous performance task, however, the total score was neither related to any of these ERP indices (Kam et al, 2012). In contrast, Russo et al (2008) demonstrated that lower P3 amplitudes in a two-choice visual oddball task predicted higher BIS total score.…”

“…In the DSM (DSM-IV-TR; American Psychiatric Association 2000), impulsivity is the second most frequent symptom (Boy et al, 2011). There is a growing interest in understanding impulsivity among healthy populations as this trait can be interpreted along a dimension, but the underlying mechanisms across the full range have not been clarified yet (Dimoska and Johnstone, 2007;Kam et al, 2012;Stanford et al, 2009). The present study aimed to elucidate the neuro-cognitive background of trait impulsivity by means of ERP components, focusing on inhibitory control and energetic factors.…”

Impaired inhibitory control is one of the still debated underlying mechanisms of trait impulsivity. The Cognitive Energetic Model accounts for the role of energetic factors mediating task performance. The aim of the present study was to compare inhibitory control functions of adults with high and low impulsivity by using a modified Eriksen flanker task.Adults were classified as impulsive (n = 15) and control (n = 15) participants based on the Barratt Impulsiveness Scale. Flanker trials had three levels of required effort manipulated by visual degradation. We analyzed RT, accuracy, and ERPs time-locked to the flanker stimuli.Reaction time of impulsive participants was generally slower than that of controls', but accuracy was similar across groups. N2c showed that monitoring of response conflict was modulated by task requirements independent of impulsivity. The P3 latency was delayed in the impulsive group indicating slower stimulus evaluation. The P3 amplitude was reduced in the control group for moderately degraded incongruent trials suggesting that the attentional resources were employed less. The Lateralized Readiness Potential (LRP) peaked later in the impulsive group irrespective of experimental effects. The amplitude of the positive-going LRP recorded in the incongruent condition was comparable across groups, but the latency was delayed partly supporting a stronger susceptibility to stimulus interference of impulsive participants. Their delayed incongruent negative-going LRP reflected a weaker response inhibition and a slower correct response organization. In conclusion, impaired inhibitory functions in impulsivity could not be unequivocally demonstrated, but we found a generalized lapse of motor activation.

“…These relationships indicate that individuals with an extra-frontal lesion may display DF and that DF is strongly associated with aspects of impulsivity. There is evidence that EF and impulsivity are related (Kam et al 2012), and show higher attentional impulsivity in impulsive action associated with EF's performance, in a way that, the higher the dysfunction, the higher the impulsivity.…”

The aim of this study was to evaluate executive functioning (EF) and impulsiveness in three groups of people aged 30 to 79 years: post-frontal stroke (n = 13) and post-extra-frontal chronic stroke of the right hemisphere (n = 31) and control (n = 38). The years of education varied between the groups was as follows, frontal lesion group: M = 12 (SD = 6.11); extra-frontal lesion group: M = 9.06 (SD = 4.94); and control: M = 9.61 (SD = 4.24) years. The following instruments were used: Behavioural Assessment Dysexecutive Syndrome, Wisconsin Card Sorting Test (WSCT), Barratt Impulsivity Scale, Impulsivity Evaluation Scale, Delay Descounting Task and Go/No-Go Task. We found differences in EF between the extra-frontal lesion group and the control group with respect to cognitive flexibility (p = .018); number of WCST trials (p = .018); WCST perseverative errors (p = .014) and omission by impulsivity errors on the go/no-go task for 250 ms (p = .008) and 1750 ms trials (p = .006). The frontal lesion group made more errors of omission than the control group in the 1750 ms go/no-go trials (p = .006). These results suggest that extra-frontal lesions impair EF by influencing attentional impulsivity.
