By making use of event-related potential (ERP) technology, a randomized, double-blind, between-subject design study was performed in order to investigate whether OXT can weaken men’s self-other distinction during empathic responses to sad expressions. In the two experimental tasks, 39 male subjects were asked to either evaluate the emotional state shown in a facial stimulus (other-task) or to evaluate their own emotional responses (self-task). The results revealed that OXT reduced the differences in P2 (150–200 ms) amplitudes between sad and neutral expressions in the self-task but enhanced P2 to sad expressions in the other-task, indicating OXT’s role in integrating the self with others instead of separating them. In addition, OXT also reduced the LPC (400–600 ms) amplitudes between sad-neutral expressions in the self-task, implying that OXT’s weakening effects on the self-other distinction could occur at both the early and late cognitive control stages of the empathic response.

The Relationship

Contemplative practices are thought to modify one’s experience of self and fundamentally change self-referential processing. However, few studies have examined the effect of long-term meditation training on brain correlates of self-referential processing. Here we used the self-referential encoding task (SRET) to examine event-related potentials (ERP) during assessment of positive and negative self-views in long-term meditators versus demographically-matched meditation-naïve control participants. Compared to controls, meditators endorsed significantly more positive and less negative words as self-referential. We also found a between-group difference in the early component of the late-positive-potential (LPP) of the ERP characterised by a higher response to negative versus positive words in controls and no difference in meditators. These findings suggest that long-term meditation training alters self-referential processing towards a more adaptive view of self and neural equivalence towards positive and negative self-views. Such changes may be one aspect of how meditation modifies the relationship to self.

The present study analyzed event-related potentials (ERPs) in different valence conditions to investigate whether negativity bias can occur prior to the experiencing of negative emotion. There were two tasks: One was challenging and participants were asked to react as quickly as possible; the other was easy and participants were asked to react after the stimuli disappeared. ERPs were compared to determine if negativity bias had occurred. Anterior hemispheric asymmetries tests (AHAT) were conducted to test emotion-evoking effects. The ERP results showed that negativity bias occurred in both tasks. However, AHAT showed that emotion was not effectively evoked in the challenging task. These results suggested that negativity bias could occur even without effective experiencing of emotion. This prompted a new viewpoint regarding the properties of negativity bias: Early negativity bias was caused by the features of negative stimuli but not by negative emotions.

Abstract A large literature in social neuroscience has associated the medial prefrontal cortex (mPFC) with the processing of self-related information. However, only recently have social neuroscience studies begun to consider the large behavioral literature showing a strong self-positivity bias, and these studies have mostly focused on its correlates during self-related judgments and decision-making. We carried out a functional MRI (fMRI) study to ask whether the mPFC would show effects of the self-positivity bias in a paradigm that probed participants’ self-concept without any requirement of explicit self-judgment. We presented social vignettes that were either self-relevant or non-self-relevant with a neutral, positive or negative outcome described in the second sentence. In previous work using event-related potentials, this paradigm has shown evidence of a self-positivity bias that influences early stages of semantically processing incoming stimuli. In the present fMRI study, we found evidence for this bias within the mPFC: an interaction between self-relevance and valence, with only positive scenarios showing a self vs other effect within the mPFC. We suggest that the mPFC may play a role in maintaining a positively biased self-concept and discuss the implications of these findings for the social neuroscience of the self and the role of the mPFC.

Neuroimaging, behavioral, and self-report evidence suggests that there are four main cognitive mechanisms that support mindfulness: (a) self-regulation of attention, (b) improved body awareness, (c) improved emotion regulation, and (d) change in perspective on the self. In this article, we discuss these mechanisms on the basis of the event-related potential (ERP). We reviewed the ERP literature related to mindfulness and examined a data set of 29 articles. Our findings show that the neural features of mindfulness are consistently associated with the self-regulation of attention and, in most cases, reduced reactivity to emotional stimuli and improved cognitive control. On the other hand, there appear to be no studies of body awareness. We link these electrophysiological findings to models of consciousness and introduce a unified, mechanistic mindfulness model. The main idea in this refined model is that mindfulness decreases the threshold of conscious access. We end with several working hypotheses that could direct future mindfulness research and clarify our results.
