The Neural Correlates Underlying Belief Reasoning for Self and for Others: Evidence from ERPs
نویسندگان
چکیده
Belief reasoning is typical mental state reasoning in theory of mind (ToM). Although previous studies have explored the neural bases of belief reasoning, the neural correlates of belief reasoning for self and for others are rarely addressed. The decoupling mechanism of distinguishing the mental state of others from one's own is essential for ToM processing. To address the electrophysiological bases underlying the decoupling mechanism, the present event-related potential study compared the time course of neural activities associated with belief reasoning for self and for others when the belief belonging to self was consistent or inconsistent with others. Results showed that during a 450-600 ms period, belief reasoning for self elicited a larger late positive component (LPC) than for others when beliefs were inconsistent with each other. The LPC divergence is assumed to reflect the categorization of agencies in ToM processes.

The neural correlates of reasoning about prosocial-helping decisions: an event-related brain potentials study.
Providing help to others is a highly valued social practice. This study used neurophysiological methods to explore the neural correlates of individuals' reasoning about prosocial-helping behaviors and the relation between these correlates and self-reports of prosocial personality. Event-related potentials (ERP) were recorded while individuals reasoned about others' decisions to provide help or ...
متن کاملNeural Correlates of Craving in Methamphetamine Abuse
Introduction: Methamphetamine is a powerful psychostimulant that causes significant neurological impairments with long-lasting effects and has provoked serious international concerns about public health. Denial of drug abuse and drug craving are two important factors that make the diagnosis and treatment extremely challenging. Here, we present a novel and rapid noninvasive method...
متن کاملPsychosis-Proneness and Neural Correlates of Self-Inhibition in Theory of Mind
Impaired Theory of Mind (ToM) has been repeatedly reported as a feature of psychotic disorders. ToM is crucial in social interactions and for the development of social behavior. It has been suggested that reasoning about the belief of others, requires inhibition of the self-perspective. We investigated the neural correlates of self-inhibition in nineteen low psychosis prone (PP) and eighteen hi...
متن کاملExploring Neural Correlates of Different Dimensions in Drug Craving Self-Reports among Heroin Dependents
Introduction: Drug craving could be described as a motivational state which drives drug dependents towards drug seeking and use. Different types of self-reports such as craving feeling, desire and intention, wanting and need, imagery of use, and negative affect have been attributed to this motivational state. By using subjective self-reports for different correlates of drug craving along ...
متن کاملInhibit yourself and understand the other: Neural basis of distinct processes underlying Theory of Mind
Taking the perspective of somebody else (Theory of Mind; ToM) is an essential human ability depending on a large cerebral network comprising prefrontal and temporo-parietal regions. Recently, ToM was suggested to consist of two processes: (1) self-perspective inhibition and (2) belief reasoning. Moreover, it has been hypothesized that self-perspective inhibition may build upon basic motor respo...
