北京大学生多元自尊的解析

该研究试图考察北京大学生的整体自尊、多元自尊的特点,探讨整体自尊的结构,考察它与抑郁等消极情绪的关系。研究采用华人多元自尊量表、华人整体自尊量表,在北京地区18所高校中,随机选取300名大学生施测。结果显示:1)多元自尊存在性别差异和年级差异;2)在北京大学生的多元自尊中,个人独立与能力自尊、人际关系与人缘自尊以及家世背景与经济自尊是自尊结构中的主要维度,能够有效预测整体自尊;3)整体自尊与焦虑、抑郁、以及消极情绪的强度与频率都存在显著的负相关。     

风水先生总是“有理”

我的老家在毛主席诗词“五岭逶迤腾细浪,乌蒙磅礴走泥丸”的那个五岭之一的萌堵岭之南麓,在旧社会,那里山高路远,交通闭塞,直到解放初期还是只有一条砂石土路通到县城,科学进不去,延绵了数千年的封建迷信却在那里繁衍生殖,颇为兴旺。小小的一个山区县城,什么巫婆、道士、神汉和风水先生应有尽有。人们求神拜佛讲风水的风气也很浓。记得,当时有一个陈姓街民,外号叫“活神仙”,三十挂零,尚未娶妻成家立业,又不会做耕田种地的活,因此空闲时间也特别多。每天吃饱饭没事做,便在县城周围的大山小岭、沟沟岔岔间闲逛。真是功夫不负有心人,数年下来,…

注意瞬脱对视觉空间关系判断的影响

将RSVP范式和视觉空间关系研究范式相结合,以两个实验探讨了注意瞬脱对视觉空间关系判断的影响。结果发现,类别和数量空间关系判断之间出现了实验性分离:类别空间关系判断表现出较大的注意瞬脱效应,数量空间关系判断只有轻度注意瞬脱效应。这说明,类别和数量空间关系加工子系统具有不同信息加工特性:前者依赖实时注意资源,其编码过程更多涉及控制性加工;后者较少依赖实时注意资源,其编码过程更多涉及自动加工。另外,还运用注意瞬脱理论对结果进行了解释。     

Work attitudes,career success and health: Evidence from China

Research on the determinants and implications of career success, and in particular on how they are related to health among Chinese workers is scarce. This research explores the impact and relevance of individual attitudes of trust and organizational citizenship behavior on objective and subjective career success, and their relevance to physical and mental health. Further, we explore the moderating role of a career system on the relationships between work attitudes and career success. Using a random sample of 10,372 people in China we used multi-level linear regression methodology to explore a mediation–moderation model based on organizational theories. We found support for the impact of organizational citizenship behaviors and trust, for both objective and subjective career success as mediators of mental and physical health, and for a career system as a moderator, with significant differences emerging between workers employed in the public and private sectors. The results are important as they shed light on the relationship between work and life attitudes on outcomes of high relevance at national level. The original contribution would be of interest to policy makers at both organizational and national level.

Cocaine-but not methamphetamine-associated memory requires de novo protein synthesis

Context-induced drug craving and continuous drug use manifest the critical roles of specific memory episodes associated with the drug use experiences. Drug-induced conditioned place preference (CPP) in C57BL/6J mouse model, in this regard, is an appropriate behavioral paradigm to study such drug use-associated memories. Requirement of protein synthesis in various forms of long-term memory formation and storage has been phylogenetically demonstrated. This study was undertaken to study the requirement of protein synthesis in the learning and memory aspect of the conditioned place preference induced by cocaine and methamphetamine, two abused drugs of choice in local area. Since pCREB has been documented as a candidate substrate for mediating the drug-induced neuroadaptation, the pCREB level in hippocampus, nucleus accumbens, and prefrontal cortex was examined for its potential participation in the formation of CPP caused by these psychostimulants. We found that cocaine (2.5 and 5.0 mg/kg/dose)-induced CPP was abolished by the pretreatment of anisomycin (50 mg/kg/dose), a protein synthesis inhibitor, whereas methamphetamine (0.5 or 1.0 mg/kg/dose)-induced CPP was not affected by the anisomycin pretreatment. Likewise, cocaine-induced CPP was mitigated by another protein synthesis inhibitor, cycloheximide (15 mg/kg/injection) pretreatment, whereas methamphetamine-induced CPP remained intact by such pretreatment. Moreover, anisomycin treatment 2h after each drug-place pairing disrupted the cocaine-induced CPP, whereas the same treatment did not affect methamphetamine-induced CPP. An increase of accumbal pCREB level was found to associate with the learning phase of cocaine, but not with the learning phase of methamphetamine. We further found that intraaccumbal CREB antisense oligodeoxynucleotide infusion diminished cocaine-induced CPP, whereas did not affect the methamphetamine-induced CPP. Taken together, these data suggest that protein synthesis and accumbal CREB phosphorylation are essential for the learning and consolidation of the cocaine-induced CPP, whereas methamphetamine-induced CPP may be unrelated to the synthesis of new proteins.

Individual attitudes and perceived social norms: Reports on HIV/AIDS‐related stigma among service providers in China

This study examined HIV/AIDS‐related stigma among Chinese service providers by comparing their personal attitudes toward people living with HIV/AIDS with their perception of social norms related to people living with HIV/AIDS. We randomly selected three provincial hospitals, four city/prefecture hospitals, 10 county hospitals, 18 township health clinics, and 54 village clinics from Yunnan, China. Doctors and nurses were randomly sampled proportionally to the doctor–nurse ratio of each hospital or clinic. Lab technicians were over‐sampled in order to include an adequate representation in the analysis. A total of 1,101 service providers participated in a voluntary, anonymous survey where demographic characteristics, individual attitude and perceived social norms toward people living with HIV/AIDS, discrimination intent at work, general prejudicial attitude and knowledge on HIV/AIDS were measured. A majority of the sample demonstrated a similarity between their personal views and what they thought most people in society believe. Multiple logistic regressions revealed that participants who were younger or reported personal contact with people living with HIV/AIDS were significantly more likely to report personal attitudes toward the population that were more liberal than their perceived social norms. Holding a more liberal personal attitude toward people living with HIV/AIDS than perceived social norms was significantly and negatively related to the level of discrimination intent at work, perceived discrimination at interpersonal level and the level of general prejudicial attitude toward people living with HIV/AIDS. Results underscored the importance of understanding social norms and personal attitudes in studying HIV‐related stigma and called for the incorporation of existing human capital into future HIV stigma reduction programs.     

Posttraining infusion of cholinergic drugs into the ventral subiculum modulated memory in an inhibitory avoidance task: Interaction with the bed nucleus of the stria terminalis

The ventral subiculum (vSUB), a hippocampal efferent target implicated in learning and stress coping, receives cholinergic input and sends glutamatergic output to the bed nucleus of the stria terminalis (BNST). This study examined the roles of vSUB muscarinic activation and its interaction with BNST N-methyl-d-aspartate and noradrenergic receptors in formation of aversive memory. Male Wistar rats with cannulae implanted into the vSUB or BNST were trained on a step-through inhibitory avoidance task. Shortly after training, they received cholinergic drugs infused into the vSUB and/or glutamatergic or noradrenergic drugs infused into the BNST. Results of the 1-day retention tests showed that intra-vSUB infusion of oxotremorine (0.01 μg) or scopolamine (0.3 or 3.0 μg) enhanced or impaired retention, respectively. Both effects were dose- and time-dependent, and 0.001 μg oxotremorine attenuated the amnesia induced by 3.0 μg scopolamine. The oxotremorine-induced memory enhancement was blocked by intra-BNST infusion of dl-2-amino-5-phosphonovaleric acid or propranolol at a dose not affecting retention; the amnesia induced by scopolamine was blunted by intra-BNST infusion of glutamate or norepinephrine at a dose with a negligible effect on retention. These data suggest that in an inhibitory avoidance task muscarinic activation of the vSUB modulated memory formation by interacting with the BNST glutamatergic and noradrenergic functions.
