“…Although rapid response style has been considered as an important feature of trait impulsivity (Pailing et al, 2002;Ruchsow et al, 2005), some evidence also suggests that impulsive participants show greater response tendencies (Arce and Santisteban, 2006). Longer completion times in EF tasks measuring planning (The Maze Test: Pietrzak et al, 2008) and response organization (complex flanker task; visual oddball task: Gorlyn et al, 2005;Russo et al, 2008) have been shown in relation to increased BIS scores that partially corresponds to our present results. In our study, slower information processing at the behavioral level was also reflected in the delayed latency of different ERP components (P3 and LRPs) that might denote that the total score of BIS measures a somewhat consequent and unitary phenomenon.…”

“…These behavioral and ERP results could furthermore show that low and high impulsive groups differed particularly in processing speed, and not in conflict processing per se. Besides that previous results are mixed about the relationship between impulsivity and cognitive ability, some evidence showed that individuals with higher BIS score demonstrated impaired performance on IQ measures, and this was also reflected in reduced P3 amplitudes (Russo et al, 2008). However, Running head: Energetic factors in impulsivity 27 without any assessment of IQ or processing speed, we could not verify whether IQ differences explain our results.…”

“…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. Only one study has investigated the effect of impulsiveness on response preparation in stop-signal paradigm (Dimoska and Johnstone, 2007).…”

“…However, a reduced P3 amplitude in impulsive participants was a general result of former studies using various tasks (Chen et al, 2007;De Pascalis et al, 2004;Russo et al, 2008). This was interpreted either as an outcome of ineffective allocation of the available attentional resources, or as a consequence of attenuated physiological arousal.…”

“…This was interpreted either as an outcome of ineffective allocation of the available attentional resources, or as a consequence of attenuated physiological arousal. 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).…”

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.

Response inhibition is the ability to suppress inadequate but prepotent or ongoing response tendencies. A fronto-striatal network is involved in these processes. Between-subject differences in the intra-individual variability have been suggested to constitute a key to pathological processes underlying impulse control disorders. Single-trial EEG/fMRI analysis allows to increase sensitivity for inter-individual differences by incorporating intra-individual variability. Thirty-eight healthy subjects performed a visual Go/Nogo task during simultaneous EEG/fMRI. Of 38 healthy subjects, 21 subjects reliably showed Nogo-related ICs (Nogo-IC-positive) while 17 subjects (Nogo-IC-negative) did not. Comparing both groups revealed differences on various levels: On trait level, Nogo-IC-negative subjects scored higher on questionnaires regarding attention deficit/hyperactivity disorder; on a behavioral level, they displayed slower response times (RT) and higher intra-individual RT variability while both groups did not differ in their inhibitory performance. On the neurophysiological level, Nogo-IC-negative subjects showed a hyperactivation of left inferior frontal cortex/insula and left putamen as well as significantly reduced P3 amplitudes. Thus, a data-driven approach for IC classification and the resulting presence or absence of early Nogo-specific ICs as criterion for group selection revealed group differences at behavioral and neurophysiological levels. This may indicate electrophysiological phenotypes characterized by inter-individual variations of neural and behavioral correlates of impulse control. We demonstrated that the inter-individual difference in an electrophysiological correlate of response inhibition is correlated with distinct, potentially compensatory neural activity. This may suggest the existence of electrophysiologically dissociable phenotypes of behavioral and neural motor response inhibition with the Nogo-IC-positive phenotype possibly providing protection against impulsivity-related dysfunction.
