正确认识免疫抑制剂治疗风湿病的双刃剑作用

免疫抑制剂治疗风湿病疗效显著,但由于其免疫抑制的作用机理,临床应用会引起很多的副作用。由于患者的个体差异,治疗作用与副反应不尽相同。所以,在治疗的时候应该尽量扩大治疗作用减少副作用,并向患者阐明药物的双重性。     

The state of the psychological contract and its relation with employees' psychological health

In the present paper the role of the state of the psychological contract to predict psychological health results is studied in a sample of 385 employees of different Spanish companies. Results indicate that the state of the psychological contract significantly predicts life satisfaction, work-family conflict and well-being beyond the prediction produced by the content of the psychological contract. In addition, trust and fairness, two dimensions of the state of psychological contract, all together contribute to explain these psychological health variables adding value to the role as predictor of fulfillment of the psychological contract. The results support the approach argued by Guest and colleagues.     

Role of Sexual Orientation and Gender-Related Traits in Disordered Eating

This study was designed to examine the role of both sexual orientation and gender-related personality traits in disordered eating attitudes and behavior, including body dissatisfaction. Self-report measures assessing negative and positive gender traits,body dissatisfaction, drive for thinness, dietary restraint, and bulimic symptoms were administered to 266 participants (64 lesbians, 73 heterosexual women, 69 gay men, and 60 heterosexual men; 85% Anglo-Australian Caucasians, 15% Caucasians from Non-English-speaking backgrounds). Consistent with previous research, gay men scored significantly higher than heterosexual men on body dissatisfaction and dietary restraint, whereas lesbians scored significantly lower in comparison to the heterosexual women on body dissatisfaction, drive for thinness, dietary restraint, and bulimia. For men, the additional amount of variance accounted by the gender traits was significantly higher than that accounted for by sexual orientation. For the women, the gender traits also accounted for an additional significant amount of variance; however, overall the amount of variance accounted for by sexual orientation was greater. However, for both men and women, irrespective of their sexual orientation, it was higher scores on negative femininity that predicted higher levels of disordered eating. These results are consistent with previous studies that have found support for the femininity hypothesis in disordered eating.     

道德概念垂直空间隐喻理解中的映射:双向性及不平衡性

通过4个实验考察道德概念垂直空间隐喻理解中的映射机制和特征。实验1采用空间Stroop范式,发现被试判断完道德词后,对判断随后呈现在屏幕上方或下方字母的反应时的差异不显著,没有发现词汇类型对空间位置的影响。实验2采用有意识迫选法,要求被试出声读出屏幕中央的道德词后,对屏幕上方或下方的希腊语非词进行二择一迫选,发现被试读出道德词后倾向于选择屏幕上方的非词,读出不道德词后倾向于选择屏幕下方的非词。实验3仍采用Stroop范式,发现被试做出空间"上"的判断后,对随后道德词的词义判断反应时显著快于不道德词,做出空间"下"的判断后,对不道德词的反应时显著快于道德词。实验4探讨空间位置是否会对判断人物的道德性产生影响,结果发现被试倾向于认为屏幕上方的人物是道德的,而屏幕下方的人物是不道德的。4个实验的结果表明,在道德概念垂直空间隐喻的理解中,映射的方式是灵活的、双向的,既可以由始源域向目标域映射,也可以由目标域向始源域映射,但两个方向上的映射力量是不平衡的。     

错误信息效应的主要理论与影响因素的述评与展望

个体对原始信息的记忆受到随后错误信息的影响而产生错误记忆被称为错误信息效应.通过对新近研究的梳理与归纳,发现错误信息效应的研究热点集中于解释效应产生机制的理论研究以及效应的影响因素研究.因此,本文重点归纳和述评了错误信息效应的五种理论和三类影响因素.未来的研究建议从以下几方面开展:第一,错误信息产生机制和理论研究;第二...     

Gender Traits and Self-Concept as Indicators of Problem Eating and Body Dissatisfaction Among Children

The present study was designed to examine the role of gender traits, body mass index (BMI), and self-concept in predicting levels of problem eating and body dissatisfaction among both girls and boys aged between 8 and 10 (85% were Anglo-Australian Caucasian, 15% were Caucasians from non-English backgrounds). Two hundred and two children completed questionnaires, which examined problem-eating attitudes and behaviors, body dissatisfaction, gender traits, and self-concept. Children's height and weight were measured to determine children's BMI. Gender traits predicted problem eating for boys but not for girls. Self-concept was found to predict problem eating for both boys and girls. BMI was also a predictor of problems for girls. The only predictor of body dissatisfaction for boys and girls was BMI. The findings are discussed in light of previous research, which has been conducted, on adolescents. Further studies are needed to understand more fully the development of problem eating and body dissatisfaction before the onset of puberty and adolescence.     

Professionalism Among Chinese Engineers: An Empirical Study

反馈相关负波与成瘾

反馈相关负波(feedback-related negativity, FRN)是反馈加工诱发的脑电成分, 体现了个体对奖赏的敏感性。成瘾分为物质成瘾和行为成瘾, 两类个体的反馈加工都呈现病理性模式。相对于普通反馈物(如金钱), 物质成瘾个体在加工成瘾物质时诱发的FRN波幅显著增大; 在与非成瘾被试的对照研究中, 物质成瘾者加工金钱反馈时的FRN也表现出与成瘾相关的异常模式; 在行为成瘾个体中亦观察到与物质成瘾个体类似的FRN失调现象。但以往多数研究中对成瘾类型的区分还不够详细, 未来研究应进一步考虑成瘾不同亚型的特点; 且成瘾个体往往伴随其他精神障碍(如抑郁、焦虑), 将来的研究要区分共病因素的影响, 揭示成瘾独特的奖赏加工机制问题。     

情绪对联合行动中共同表征能力的影响机制

采用联合Simon任务通过3个实验探究不同情绪维度对联合任务中共同表征能力的影响机制。实验1a、1b分别考察在高、低唤醒度条件下不同效价对个体共同表征能力的影响; 实验2在此基础上进一步探索动机维度在其中的作用。结果发现：无论效价高低, 高唤醒度都是提高个体共同表征能力的关键因素, 且动机强度在其中起一定调节作用; 而在低唤醒度条件下, 高效价会起一定补偿作用。上述结果很好地支持了参照编码假说, 也澄清了情绪不同维度对联合动作表征的影响机制。
