自然数码奇象记忆法记忆复杂数字的神经机制

本研究采用学习-再认范式和复杂数字记忆材料,考察自然数码奇象记忆法相对于机械记忆法在记忆提取上的优势及神经机制。行为结果表明,自然数码奇象记忆法比机械记忆法的再认准确率更高。事件相关电位分析结果显示,再认提取阶段奇象记忆条件下诱发的N400和N700波幅显著更低,这说明奇象记忆提取更容易。在自然数码奇象记忆条件下,正确再认旧数字诱发的前额区、左顶枕叶区及中顶枕叶区N700成分与使用自然数码奇象记忆有关。本研究表明,采用自然数码奇象记忆可以减少或跨越语义加工,从而提高个体对材料的记忆效率。     

Attentional characteristics of different types of individuals with high self-esteem in self-threatening situations

The high self-esteem (HSE) heterogeneity hypothesis provides a new research perspective for investigating differences in the quantity and quality of different types of self-esteem. The present study adopted the emotional Stroop paradigm and the odd-one-out search task to explore how individuals with different types of self-esteem process social information in self-threatening situations. The results showed that individuals with different types of self-esteem had an attentional bias toward negative information and had different attentional biases toward angry faces in self-threatening situations. Individuals with fragile HSE and low self-esteem showed facilitated attention to angry faces and had difficulty drawing attention away from them; secure HSE individuals only showed difficulty disengaging attention from angry faces.

     

Inhibitory control and set shifting describe different pathways from behavioral inhibition to socially anxious behavior

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top‐down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent‐reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent‐reported inhibitory control or lower levels of parent‐reported set shifting. These data reinforce the notion that top‐down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence.     

Majority world successes and European and American failure to contain COVID‐19: Cultural collectivism and global leadership

United Nations and World Health Organization data show a positive correlation, r = .53, p < .0001, N = 189, between COVID‐19 infection rates and the human development index (HDI). Less wealthy, less educated countries with lower life spans were also more successful in maintaining lower fatality rates, r = .46, p < .0001, N = 189 whereas 9 of the top‐10 countries in the world in per capita fatalities due to COVID‐19 were Western societies high in HDI. Similar positive correlations were found between COVID‐19 infection and fatality rates and a smaller sample of 76 countries measured on Schwartz intellectual autonomy (or individualism), and negative correlations of similar magnitude were found for embeddedness (or collectivism). East Asia was a global leader in preventing the spread of COVID‐19 because of a vigilant public concerned for public safety and compliant with public safety measures. African Union leaders coordinated their responses, and bought into a continent‐wide African Medical Supplies Platform that prevented panicked competition for scare supplies. Western global media and scholars have not paid attention to the successes of East Asia, Africa, and the South Pacific in fighting the pandemic. It is worth asking why this should be the case; understand the weaknesses of extreme individualism in fighting a pandemic requiring coordinated and unified public response, and consider the lessons for global scholars from the pandemic for doing research in the future.     

Selfish power and unselfish status in Chinese work situations

The present research explored the selfishness of power and status as well as the mechanism in Chinese work situations. By using experimental and survey methods, two studies were designed to investigate the relationships among power, status, and self‐interested behaviour (SIB) as well as the mediating effect of perspective‐taking (PT). Results of the two studies consistently indicated that power increases whereas status reduces SIB. These opposing behavioural effects are partially attributed to the fact that power reduces whereas status increases PT. In addition, our results showed an interaction between power and status on SIB in Study 1 (interaction as a mental function), and a positive correlation between perceived power and status in Study 2 (correlation as a mental perception). Through the discussion from the perspective of the self/other‐orientation trait, as well as the stable effects of power and status on SIB in the two studies, we conclude that power is selfish and status is unselfish in Chinese work situations.     

EDITORIAL Building bridges with mixed methods research?

Mixed methods refers to the use of both qualitative and quantitative approaches and methods in one study or sequentially in two or more studies. Without a mixed methods approach there is – to our minds ‐ a risk that only part of a phenomenon or experience is being explored. Our own involvement in mixed methods research has grown out of a shared interest in the concept ‘research‐practitioner’. Psychotherapy is a notoriously complex and ever‐developing field, and our growing sense has been that mixed methods research can contribute to a more complete – both broad and deep ‐ sense of knowledge and understanding.     

从端粒和端粒酶探析冥想对压力的缓解作用

冥想是一种维持自我注意的身心调节技术,是缓解因压力所致的抑郁、焦虑等消极情绪的有效方法。端粒是维持染色体稳定和完整的DNA片段,大量有关冥想对端粒及端粒酶活性影响的研究阐明,通常情况下压力人群经过冥想训练能提高端粒长度并增加端粒酶活性,这种改变与压力缓解密切相关。这一积极效果主要得益于皮质醇和炎症等生物因素及心理和环境等非生物因素。未来可以通过对比不同冥想练习的效果、增加追踪研究、多学科联合及扩大样本等找到最有利于提高端粒长度和端粒酶活性的冥想方式。

Effects of fluprazine (DU 27716) upon aggressive and sexual behavior of testosterone-treated female rats

Female rats, chronically treated with Testosterone Propionate (TP), were injected with Fluprazine (DU 27716) or saline and tested for social aggression, masculine and feminine sexual behavior. Fluprazine-treated females were less aggressive than saline-treated females, as indicated by a shift from offensive to less offensive parameters of aggression. At the same time, mounting in Fluprazine-treated females was almost totally abolished, both in aggression tests and in tests for sexual behavior. Feminine sexual responses increased during aggressive encounters but were slightly inhibited when females were confronted with sexually active males. Females treated with Fluprazine and tested for mounting with a receptive female showed a substantial increase of offensive aggression directed at the receptive stimulus female. It is concluded that Fluprazine does not selectively inhibit offensive aggression in TP-treated female rats.
