Your Face Says It All: Closeness and Perception of Emotional Expressions Among Females

The purpose of the present investigation was to assess whether interpersonal closeness facilitates earlier emotion detection as the emotional expression unfolds. Female undergraduate participants were either paired with a close friend or an acquaintance (n = 92 pairs). Participants viewed morphed movies of their partner and a stranger gradually shifting from a neutral to either a sad, angry, or happy expression. As predicted, findings indicate a closeness advantage. Close friends detected the onset of their partners’ angry and sad expressions earlier than acquaintances. Additionally, close friends were more accurate than acquaintances in identifying angry and sad expressions at the onset, particularly in non-vignette conditions when these expressions were void of context. These findings suggest that closeness does indeed facilitate emotional perception, particularly in ambiguous situations for negative emotions.     

When the poor excel: Poverty facilitates procedural learning

Recent research has shown that poverty directly impeded cognitive functions because the poor could be easily distracted by monetary concerns. We argue that this effect may be limited to functions relying on working memory. For functions that rely on proceduralized processes however, monetary concerns elicited by reminding of financial demands would be conducive rather than harmful. Our results supported this hypothesis by showing that participants with lower income reached the learning criterion of the information‐integration categorization task faster than their more affluent counterparts after reminding of financial demands.     

Individual-based relative deprivation (IRD) decreases prosocial behaviors

Five studies investigated the relationship between individual-based relative deprivation (IRD) and prosocial behaviors. Study 1 found that income satisfaction, a concept closely related to IRD, was negatively associated with prosocial values across cultures. Study 2 found a negative association between IRD and prosocial aspirations among a sample of Chinese university students. Study 3 revealed a negative association between IRD and volunteer behaviors. In Studies 4 and 5, we found that laboratory-induced IRD decreased undergraduate students’ prosocial values and behaviors. Moreover, Study 5 also found that the tendency to prioritize self-interest over others’ mediated the effect of IRD on prosocial behaviors. Implications of these findings are discussed.     

The divergent effects of fear and disgust on unconscious inhibitory control

Previous studies have shown that negative emotional distracters impair conscious inhibitory control. Recent research has shown that inhibitory control can be triggered unconsciously; therefore, in Experiment 1, we aimed to investigate whether negative emotional distracters affect unconscious inhibitory control. Furthermore, in Experiment 2, we examined whether fearful and disgusting distracters have differential effects on unconscious inhibitory control. Participants were instructed to perform a masked Go/No-Go task superimposed on a negative or neutral image cue (Experiment 1) or on a fearful, disgusting or neutral image cue (Experiment 2). Results showed that negative emotional distracters impaired unconscious inhibitory control; furthermore, disgusting distracters impeded unconscious inhibitory control when compared to fearful ones. This study is the first to provide evidence that fear and disgust may affect unconscious inhibitory control differently. These results expand the understanding of the relationship between emotions and inhibitory control.     

Retention and thermal desorption of helium in pure tungsten

Tungsten (W) is cited as a candidate first-wall material in fusion reactors owing to its outstanding thermal properties and erosion resistance. An important issue is that the energetic isotopes of hydrogen, tritium (T) and deuterium (D) and helium (He) particles damage the surface of W in fusion reactors. He particles cause more notable damage than D or T because the binding energy of defects and He is larger than that of defects and D or T. In this study, well-annealed W specimens were implanted with 5 keV He ions at room temperature and irradiation dosages of 1.0 × 10²⁰ and 2.5 × 10²¹ ions/m². Then, thermal desorption spectroscopy analysis was performed by heating the samples to 1973 K at a ramping rate of 0.5 K/s. Thermal desorption of He in the sample irradiated with a low dosage occurred at 1400 and 1960 K, whereas that in the sample irradiated with a high dosage occurred at 740, 1050 and 1500 K. According to the microstructures observed using transmission electron microscopy, both peaks in the former case were attributed to He de-trapping from irradiation to nduced helium-vacancy clusters of different sizes, whereas the peaks in the latter case were attributed to He de-trapping from surface defects, irradiation-induced dislocation loops and tiny helium-vacancy clusters, respectively.     

On the role of Ag in enhanced age hardening kinetics of Mg–Gd–Ag–Zr alloys

The addition of Ag to the age hardenable Mg–Gd–Zr alloy system dramatically enhances early stage age hardening kinetics. Using atom probe tomography (APT), Ag-rich clusters were detected in a Ag-containing Mg–Gd–Zr alloy immediately after solution treatment and water quenching. During subsequent isothermal ageing at 200 °C, a high density of basal precipitates was observed during the early stages of ageing. These basal precipitates were enriched with Ag and Gd, as confirmed by APT. It is posited that Ag-rich clusters in the context of quenched-in vacancies can attract Gd atoms, increasing diffusion kinetics to facilitate the formation of the Ag + Gd-rich basal precipitates. The rapid formation of Ag + Gd-rich precipitates was responsible for accelerated ageing.     

“发现”康德先天观念综合与商品交换关系现实抽象的关联——索恩-雷特尔《脑力劳动与体力劳动》初解

索恩-雷特尔第一次明确提出用历史唯物主义的方式重新解读康德的"认识论革命",在他这里,康德的认识论构架本身是商品生产中发生的特定历史结果,知识的形式能够先验于感性世界,恰恰因之于脑力劳动从体力劳动中的历史性挣脱和分离。这种分离遮蔽了劳动创造性关系在商品交换活动的现实抽象所生成的一种构序社会存在的客观的社会先验性,而这种社会先验才是康德-黑格尔先验观念的真正根据。索恩-雷特尔第一次指认了商品交换中发生的现实抽象并不仅仅是主观思维的活动机制,作为概念生成的真正劳作工地是发生于社会存在中的一种客观抽象,恰恰是这种现实抽象建构了先验的社会生活形式,并由此规制了思维形式的主观抽象活动以生成思维形式。     

The Influence of Family Socio-economic Status on Learning Burnout in Adolescents: Mediating and Moderating Effects

According to family investment theory, a family’s socio-economic status can have a noteworthy impact on the academic performance and future lives of adolescents. However, the mechanism for this remains poorly understood. We examined the mediating and moderating effects of family emotional and cultural environment on the relations between family socio-economic status and learning burnout. Specifically, we investigated whether different family emotional environments have a moderating effect on the relationship between family socio-economic status and learning burnout and on the mediating effect of family cultural environment. A sample of 1181 junior and senior high school students completed multidimensional measures of family socioeconomic status, family emotional and cultural environment, and learning burnout. A regression analysis showed that socio-economic status significantly predicted learning burnout. The achievement, cultural, and recreational dimensions of family cultural environment were all mediators of this relationship. Moreover, cultural dimension was moderated by the family conflicts factor of family emotional environment.
