Human voluntary response inhibition has frequently been investigated using go/no-go RT tasks. Recent studies have indicated that not only the traditional averaging waveforms of EEG activities (ERPs) but also the power and phase dynamics of single-trial EEG are important in studying the neural correlates of various human cognitive functions. Therefore, here, we aimed to undertake a detailed study of the time/frequency power and phase dynamics of single-trial EEG during go/no-go RT tasks, with focus particularly on the no-go-specific power and phase dynamics, which are presumed to involve the voluntary response inhibition processes. Thus, we demonstrated no-go-specific theta band EEG power increases and intertrial phase-locking in the midline-frontal areas, which are related to no-go-specific midline-frontal negative–positive ERP waveforms (no-go N2/no-go P3). In addition, we observed no-go-specific alpha band EEG intertrial phase-locking with an adjacent dephasing phenomenon, which is mainly associated with the early part of no-go N2. The estimated time point when the no-go-specific midline-frontal dephasing phenomenon occurred corresponded to the initial part of the voluntary response inhibition process (decision to withhold). Moreover, the no-go-specific phase dynamics in the midline-frontal areas just before and around the no-go N2 peak latency, unlike the power modulations, were affected by changes in the no-go stimulus probability, suggesting the dependence of only phase dynamics on no-go stimulus probability. From these results, we conclude that the complex power and phase dynamics of the theta and alpha band EEG in the midline-frontal areas are specific to no-go trials, being the underlying bases of the no-go-specific ERP waveforms, and suggest that the phase dynamics just before and around the no-go N2 peak latency may involve, at least, the initial part of the voluntary response inhibition process (decision to withhold).

This article explores the contribution of differences in motor response initiation and execution to the biological bases of extraversion. Specifically, we examined individual differences in the lateralized readiness potential (LRP) for introverts and extraverts under conditions influencing stimulus evaluation time prior to response execution, i.e., stimulus information value and tonal complexity. The salient effects were longer stimulus-locked LRP and shorter response-locked LRP for extraverts than introverts to simple imperative stimuli to respond. The present studies (1) confirm that extraverts initiate movement faster and are less efficient than introverts in the processing of simple stimulus signals to respond and (2) endorse the view differences in sensory-motor processing are important determinants of variation in Extraversion.

Abstract Several studies have shown faster choice-reaction times to positive than to negative facial expressions. The present study examined whether this effect is exclusively due to faster cognitive processing of positive stimuli (i.e., processes leading up to, and including, response selection), or whether it also involves faster motor execution of the selected response. In two experiments, response selection (onset of the lateralized readiness potential, LRP) and response execution (LRP onset-response onset) times for positive (happy) and negative (disgusted/angry) faces were examined. Shorter response selection times for positive than for negative faces were found in both experiments but there was no difference in response execution times. Together, these results suggest that the happy-face advantage occurs primarily at premotoric processing stages. Implications that the happy-face advantage may reflect an interaction between emotional and cognitive factors are discussed.
