COVID-19 reopening of China in the context of the highly transmissible Omicron variant has resulted in an unprecedented wave of infections, placing significant strain on healthcare systems and giving rise to a range of psychological responses, including perceptions of the pandemic's threat, emotional reactions, and prosocial intentions amid moral conflicts over medical resource scarcity and evolving public health responses. This study employed a comprehensive approach integrating surveys, behavioral experiments, and agent-based modeling (ABM) to examine these psychological impacts of COVID-19 reopening. A total of 1,675 participants from 34 Chinese provinces completed the surveys, with 587 also undertaking the reversal-learning task.

Culture is a complex topic involving a comprehensive representation of human institutions, social customs, norms, and lifestyles. Over the past half-century, the methods of cultural studies have improved dramatically in the depth of the research questions posed. However, most contemporary research on cultural issues is conducted from a single perspective, which fails to account for the holistic and extensive nature of culture.

Article Synopsis
  • A study was conducted to investigate the effectiveness of different edge designs for occlusal veneers on maxillary first molars, emphasizing the need for standardized clinical protocols due to varying research outcomes.
  • The research involved creating 3D models of teeth and testing three edge designs (SFL, CFL, SCI) with varying thicknesses (0.5 mm and 1.0 mm), using finite element analysis to assess stress distribution under bite forces.
  • Results showed that increased veneer thickness raised stress in SFL and CFL designs, while SCI saw reduced stress; however, SCI also risked exceeding adhesive strength, suggesting potential issues with this design in clinical settings.*

Article Synopsis
  • Studies show the brain's empathic response is stronger for those within the same racial group compared to others, but the role of oxytocin in this response is unclear.
  • Functional MRI scans were used to explore neural activities in response to racial ingroup bias while considering oxytocin's effects; participants were given either oxytocin or a placebo and judged painful stimuli in same-race and other-race scenarios.
  • Results indicated that genetic variations in the oxytocin receptor influenced brain activity in regions connected to empathy, with higher activity linked to interpersonal trust levels and intentions for revenge in low-trust situations.

Bacterial biofilm is a three-dimensional matrix composed of a large number of living bacterial individuals. The strong bio-interaction between the bacteria and its self-secreted matrix environment strengthens the mechanical integrity of the biofilm and the sustainable resistance of bacteria to antibiotics. As a soft surface, the biofilm is expected to present different dynamical wetting behavior in response to shear stress, which is, however, less known.

This paper provides a unique perspective for understanding cultural differences: representation similarity-a computational technique that uses pairwise comparisons of units to reveal their representation in higher-order space. By combining individual-level measures of trust across domains and well-being from 13,823 participants across 15 nations with a measure of society-level tightness-looseness, we found that any two countries with more similar tightness-looseness tendencies exhibit higher degrees of representation similarity in national interpersonal trust profiles. Although each individual's trust profile is generally similar to their nation's trust profile, the greater similarity between an individual's and their society's trust profile predicted a higher level of individual life satisfaction only in loose cultures but not in tight cultures.

An astonishing cultural phenomenon is where, far away from or close to a city center, people in different societies localize cemeteries that function as both sites of memory of lost ones and symbols of mortality. Yet a psychological account of such differences in behavioral responses to symbols of mortality is lacking. Across five studies ( = 1,590), we tested a psychological model that religious afterlife beliefs decrease behavioral avoidance of symbols of mortality (BASM) by developing and validating a word-position task for quantifying BASM.

Both monetary loss and pain have been studied for decades, but evidence supporting the relationship between them is still lacking. We conducted a meta-analysis to explore the overlapping brain regions between monetary loss and pain, including physical pain and social pain. Regardless of the type of pain experienced, activation of the anterior insula was a shared neural representation of monetary loss and pain.

As the weakest links in information security defense are the individuals in an organizations, it is important to understand their information security behaviors. In the current study, we tested whether the neural variability pattern could predict an individual's intention to engage in information security violations. Because cognitive neuroscience methods can provide a new perspective into psychological processes without common methodological biases or social desirability, we combined an adapted version of the information security paradigm (ISP) with functional magnetic resonance imaging (fMRI) technology.

With the deepening of internationalization, the population's mobility has greatly increased, which can impact people's intergroup relationships. The current research examined the hypothesis that residential mobility plays a crucial role in racial in-group bias in empathy (RIBE) with three studies. By manipulating the residential mobility/stability mindset and measuring subjective pain intensity ratings (Study 1) and event-related potentials (ERPs, Study 2) of Chinese adults on painful and neutral expressions of Asian and Caucasian faces, we found that the RIBE in subjective ratings and N1 amplitudes increased and P3 amplitudes decreased in the stability group.

Although research in the field of cultural psychology and cultural neuroscience has revealed that culture is an important factor related to the human behaviors and neural activities in various tasks, it remains unclear how different brain regions organize together to construct a topological network for the representation of individual's cultural tendency. In this study, we examined the hypothesis that resting-state brain network properties can reflect individual's cultural background or tendency. By combining the methods of resting-state magnetic resonance imaging and graph theoretical analysis, significant cultural differences between participants from Eastern and Western cultures were found in the degree and global efficiency of regions mainly within the default mode network and subcortical network.

Rationale: Oxytocin has been found to play an important role in human social cognition and social interaction. Over the last two decades, surge studies have been conducted to investigate how oxytocin impacts other-oriented processes, such as trust and generosity (Zak et al. in PLoS ONE 2(11):e1128, 2007); however, the examination of the effect of oxytocin on self-related processes was relatively inadequate.

With the internationalization of human society, population mobility has greatly increased, which can affect people's psychological states and behaviors. Research on residential mobility is burgeoning, but few studies have linked this topic to decision making, particularly temporal discounting, in which individuals generally discount future gains and losses. In Study 1, we manipulated individuals' residential mobility and stability and found that residential mobility heightened temporal discounting.

Resilience, a psychological trait conceptualized as the ability to recover from setbacks, can be weakened by childhood maltreatment, which comprises childhood abuse and childhood neglect. The current study aimed to investigate whether childhood maltreatment could increase automatic negative thoughts (ANT), thus weakening resilience. Furthermore, as psychological characteristics are commonly subject to the moderating effects of cultural context and biology, the study also explored whether and how cultural and genetic factors separately interact with childhood maltreatment to predict resilience.

Social norms are essential, but they vary across cultures and societies. With the internationalization of human society, population mobility has greatly increased, especially in developing countries, which can have an impact on people's psychological states and behaviors and result in sociocultural change. The current research used three studies to examine the hypothesis that residential mobility plays a crucial role in the perception of social norm violations.
