Influence of Social Exclusion on Cool and Hot Inhibitory Control in Chinese College Students.

Social exclusion can affect nearly every aspect of a person's mental health, both on an emotional and cognitive level. The purpose of the present study was to investigate whether cool or hot inhibitory control capacity varied under social exclusion. More precisely, participants who had experienced and not experienced social exclusion were compared to explore the influence of social exclusion on cool and hot inhibitory controls.

Effects of Core Disgust and Moral Disgust on Moral Judgment: An Event-Related Potential Study.

Core disgust is elicited by physical or chemical stimuli, while moral disgust is evoked by abstract violations of moral norms. Although previous studies have pointed out these two types of disgust can affect behavior and spatial dimensions of moral judgment, less is known about how moral and core disgust affect the temporal neural processing of moral judgment. In addition, whether moral and core disgust are only related to purity-based moral judgment or all kinds of moral judgment is still controversial.

Temporal dynamics of explicit and implicit moral evaluations.

Explicit moral evaluation is often accompanied with active attention and explicit responses to moral information, while implicit moral evaluation happens in passive attention and implicit response to moral information. Previous studies have pointed out the differences in the neural mechanisms underlying explicit and implicit moral processing on the spatial dimension, however, the temporal differences between these two processes have not been clear. This study aimed at comparing the temporal dynamics between explicit and implicit moral evaluation of harm/care-related moral scenarios with high/low emotional arousal by using event-related potentials (ERP) technique.

Fearful faces modulate cognitive control under varying levels of uncertainty: An event-related potential study.

Cognitive control can reduce uncertainty, but few studies have investigated temporal dynamics of the flexible allocation of resources under varying levels of uncertainty. We used a revised majority function task with emotional faces and event-related potentials to investigate this process. The task incorporated different ratios of face orientation to quantify uncertainty.

Modulation of Mu suppression during visual perspective taking by social rejection.

Perspective taking is crucial for maintaining positive relationship with others in social interaction. Previous studies have shown that perspective-taking ability can be modulated by the experience of social rejection. The present study examined event-related dynamics of Mu power (8-13 Hz) in the EEG at sensorimotor area while rejected individuals performing visual perspective taking task.

Modulation of behavioral and brain responses to visual perspective taking by social rejection: Evidence from electrophysiology.

Visual perspective taking (VPT) is crucial for reasoning about other people's mental states. To explore the modulation of behavioral and neural responses to visual perspective taking by social rejection, we firstly manipulated rejection using get-acquainted oral communication and a two-person visual perspective task, then explored how the experience of social rejection affected the behavioral and neural responses during the follow-up classical one-person visual perspective task. The subjective rating and behavior results showed that social rejection increased individuals' negative affect level and feelings of need-threat, decreased self-regulation and impulsive control.
