Dialectical thinking is linked with smaller bilateral nucleus accumbens and right amygdala: the mediating role of sensitivity to reward

Our current work examined the interface of thinking style and mental health at both behavioral and neuropsychological levels which describe a predisposition to psychopathology. Thirty-nine Chinese participants were divided into high and low holistic thinkers based on the triad task scores, completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), and performed structural and resting-state functional magnetic resonance imaging. We found that high holistic thinkers were much less sensitive to reward than low holistic thinkers. Furthermore, their bilateral nucleus accumbens and right amygdala volumes were smaller than those of low holistic thinkers. Our integrated results showed that the relationship between holistic thinking tendency and the amygdala volume was mediated by the nucleus accumbens and the sensitivity to reward. Finally, resting-state functional connectivity results showed increased FC between left nucleus accumbens and bilateral amygdala in high holistic thinkers. The present synthetical results suggest that dialectical thinking may lead to better mental health outcomes.

The novel coronavirus (COVID-19) has infected more than 90,000 people in at least 69 countries by Feb 29, 2020. Medical interest in COVID-19 has been considerable. Mental health issues that coincide with the epidemics are rarely examined. There is a strong need for public health officials to consider how psychological effects vary at each phase of a crisis and how they relate to people to better support them in these shifting states of mind. The present study examines temporal relationships among behavioral and emotional responses towards COVID-19 and attitudinal responses to crisis management. 846 adults were invited to complete a set of Internet-based questionnaires at two time points with a range of 14 to 18 days’ intervals covered by the ascending phase of the outbreak. At the baseline assessment 788 adults completed the questionnaires. At the Wave 2 survey, 318 adults from Wave 1 were retained. Results from cross-lagged models demonstrated reciprocal negative associations between anxiety and crisis management appraise. In addition, the higher evaluation of crisis management in the initial period of outbreak predicted adoption of preventive behaviors and susceptibility to emotional contagion to a greater extend in a later period. Susceptibility to emotional contagion also positively predicted preventive behaviors taken. Furthermore, multiple group structural equation modeling revealed that evaluation of crisis management is more likely to affect the susceptibility to emotional contagion of people on the frontline of the outbreak (i.e., Wuhan) compared to people living in moderate risk areas (i.e., Outside of Hubei). These data provide experimental evidence regarding mental health during the COVID-19 outbreak, and over the course of a pandemic, which will direct governments and health authorities during disease outbreaks through their attempts to communicate with the public.
