Taking another’s perspective promotes right parieto-frontal activity that reflects open-minded thought

Abstract

2020) Taking another's perspective promotes right parieto-frontal activity that reflects open-minded thought, Social Neuroscience, 15:3, 282-295, ABSTRACTCritical thinking (CT) is important for consensus building. Although the practice of CT using debate is widely used to improve open-minded thought, the cognitive processes underlying this improvement remain poorly understood. Here, functional magnetic resonance imaging (fMRI) was employed to assess how neural responses while considering another's opinion are changed by CT practice and to determine whether the cortical network showing activation changes related to personality traits is relevant to consensus building. A total of 52 healthy participants were divided into three groups for an intervention; the participants read another's reasoning regarding a controversial issue and judged whether this person's viewpoint was affirmative during fMRI measurements. The intervention required them to prepare speech texts from a designated viewpoint based on both themselves and others. Compared to the control group, the group who took another's perspective showed enhanced activation of the right parieto-frontal network, that has been implicated in belief update, cognitive reappraisal of emotion, and self-perspective inhibition. Additionally, activation of the orbitofrontal cortex was negatively correlated with a stubbornness index. The results provide the first neural evidence of the effects of CT practice and support the notion that open-minded thought underlies the benefits of this practice. ARTICLE HISTORY

Believing and Beliefs—Neurophysiological Underpinnings

“…Likewise, it was found that a well-coordinated prefrontal-striatal network that is activated while a subject is experiencing a reward shapes preferences for future choices (Tanaka et al, 2020 ). Also, cognitive appraisal of emotions, belief updating, and self-perspective inhibition has been related to activity in a right fronto-parietal network (Miura et al, 2020 ). As a consequence, the lateral prefrontal cortex participates in the dynamic control of executive actions and in behavioral control (Mansuri et al, 2009 ).…”

“…However, adaptive personality traits are rarely associated with higher brain activation in situations where the adaptive nature of the trait is exerted. For example, among other Power to Live subscales, the adaptive trait of problem solving is associated with lower brain activation in motor-related areas ( Miura et al, 2020a ), stubbornness (i.e., resistance to social conformity pressure) in a cognitive control area ( Miura et al, 2020b ), and emotion regulation in extensive cortical regions including the prefrontal control system ( Sugiura et al, 2023 ). The concept of mindfulness ( Bishop et al, 2004 ) may be relevant to adaptive reductions of PCC activity.…”

Does the eight-factor “power to live” in disaster exist since childhood?

“…In a study in which an MRI task was used to simulate easy or difficult problems in the operation of powerplants, a relationship was found between brain activity involved in coping with difficult problems and problem-solving ( 11 ). In another study, an inverse correlation was reported between neural activation during constructive thinking and stubbornness ( 12 ).…”
