儿童状态社会创造性的跨文化研究:基于中美文化的比较

从中国和美国中部地区选取小学儿童236人,采用状态社会创造性开放问卷和教师领导方式结构式问卷考察了儿童状态社会创造性的文化差异及其与教师领导方式的关系。结果表明:(1)总体上,美国儿童在社会性问题解决中表现出较强的流畅性和变通性等创造性思维品质,但中国儿童表现出较强的适当性、有效性和冒险性等社会适应和人格状态;(2)状态社会创造性总体上存在着国别与年级之间的交互作用,美国的四年级儿童状态社会创造性得分显著高于五年级儿童;(3)教师领导方式的各个维度均不存在显著的预测作用。中美儿童的状态社会创造性既有相似之处又有不同之处。     

负面评价恐惧的性别差异:基于内隐和外显测量的比较

从内隐和外显两种角度探讨负面评价恐惧的性别差异。采用简式内隐联系测验(BIAT)和简明负面评价恐惧量表(BFNES)两种测量方法,实验共72名被试,每名被试先进行简式内隐联系测验,再完成简明负面评价恐惧量表,并借鉴不同方法对两种测量结果进行分析。结果发现:(1)被试的内隐负面评价恐惧与外显负面评价恐惧不存在显著相关,结果产生实验性分离;(2)负面评价恐惧不存在显著性别差异;(3)但有趣的是,不同性别被试内隐和外显负面评价恐惧的分离状况存在显著差异,其中男性的外显负面评价恐惧低于内隐负面评价恐惧,而女性的结果刚好相反,其外显负面评价恐惧高于内隐负面评价恐惧。这些结果表明被试的内隐和外显负面评价恐惧虽然不存在显著性别差异,但不同性别被试的内隐负面评价恐惧和外显负面评价恐惧内部存在不同的组合状况。     

Expressive writing promotes self‐reported physical,social and psychological health among Chinese undergraduates

The present study examines the efficacy of expressive writing among Chinese undergraduates. The sample comprised of 74 undergraduates enrolled in a 9‐week intervention (35 in experimental class vs. 39 in control class). The writing exercises were well‐embedded in an elective course for the two classes. The 46‐item simplified Chinese Self‐Rated Health Measurement Scale, which assesses psychological, physical and social health, was adopted to measure the outcome of this study. Baseline (second week) and post‐test (ninth week) scores were obtained during the classes. After the intervention on the eighth week, the self‐reported psychological, social and physical health of the experimental class improved. Psychological health obtained the maximum degree of improvement, followed by social and physical health. Furthermore, female participants gained more psychological improvement than males. These results demonstrated that the expressive writing approach could improve the physical, social and psychological health of Chinese undergraduates, and the method can be applied in university psychological consulting settings in Mainland China.     

The associations between parenting styles and proactive and reactive aggression in Hong Kong children and adolescents

Previous research suggests that reactive and proactive aggression may be differentially related to family contextual (e.g. parenting practices) factors. However, the existing research has focused largely on children and adolescents from Western countries, and no study has examined the parenting–aggression association using a parenting style measure sensitive to Asian culture. In this study parenting styles (i.e. warmth, control and guan/training) and proactive and reactive aggression were assessed in a large sample of school children in Hong Kong, China (N = 4,175, mean age = 11.75). We found that: (a) both low warmth (in boys only) and guan (i.e. high expectation and close supervision, in both boys and girls) were associated with elevated parent‐reported proactive aggression, (b) high restrictive control (i.e. dominating and rejecting) was associated with high reactive aggression (in both boys and girls) based on parent‐ or child‐report data, and with high proactive aggression (in boys only) based on parent‐report data, and (c) guan was also positively associated with parent‐reported reactive aggression. Findings provide more information about the Parenting Inventory using a large Asian sample, and extend existing research on familial correlates of different types of aggression.     

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.
