应激对中国地鼠糖尿病发生的影响

研究实验性应激、情绪性、笼架水平在中国地鼠糖尿病发生中的作用强度及其交互作用,以确定中国地鼠糖尿病发生危险因素。结果表明实验性应激(震动、旋转合并限制)能促使中国地鼠血糖水平显著升高,糖尿病发病率增加,发病年龄提前;高情绪性中国地鼠,随着实验时间延长,其发病率也逐渐升高,并稳定在一定水平;析因方差分析提示,实验性应激与动物情绪性的交互作用对实验后中国地鼠的血糖变化起主要作用。     

The two faces of fearless dominance and their relations to vocational success

We tested Lykken’s (1995) theory that the personality trait of fearless dominance (FD) can result in positive or negative life outcomes depending on whether the socialization process was successful or not. We tested FD’s predictive and moderated relations with vocational success over a time interval of 4 years. We found that the relations between FD and change in income were moderated by level of education. When educational level was high (low), there was a positive (negative) relation between FD and change in income. Change in income mediated the relation between FA and vocational satisfaction. Finally, FD directly predicted vocational satisfaction after 4 years. Implications and limitations are discussed.     

行动的认知表征水平

个体行动认知表征水平是与个人的行动而非一般心理功能具有特定关联的思维风格。它是一个80年代后兴起的研究领域。本文围绕行动认知表征水平研究的背景、认知表征水平与行动的交互作用以及行动认知表征水平的个体差异展开介绍。文章最后讨论了该研究的不足。     

CONTINGENT PAYMENT PROCEDURES FOR SMOKING REDUCTION AND CESSATION

We assessed the ability of a combined contingent reinforcement and intensive monitoring procedure to promote and sustain temporary smoking cessation among 34 hired research volunteers, and the ability of a smoking reduction test to predict the subsequent initiation of abstinence. During the 5-day cutdown test, subjects were paid from $0 to $6 per day depending on the extent of reduction from baseline CO levels. During the abstinence test, breath samples were obtained three times daily and subjects were paid $4 for each CO reading ≤11 ppm. Sixty-eight percent of subjects initiated abstinence. Of the breath samples collected during the abstinence test (91% of scheduled samples), 96.5% were ≤11 ppm and 80.5% were ≤8 ppm. Subjects who earned more money during the cutdown test were more likely to abstain (r = ?0.51, p < .001). Contingent reinforcement and intensive monitoring procedures appear to have usefulness for analog studies of smoking reduction and cessation.     

3─6岁儿童层级类概念发展的实验研究

以３－６岁儿童为被试,以７个常见物体种类的图片为实验材料,按概念水平（基本类概念及上级类概念）以及选择图与目标图的感知相似程度（高、中、低）将实验材料分为四种类型,对３－６岁儿童层级类概念的发展过程进行了研究。结果表明：（１）３岁幼儿已能按基本类概念标准进行正确的种类匹配;对于上级类概念,３－５岁儿童的匹配能力尚较差,６岁基本达到掌握水平。（２）实验材料的感知相似程度对３－５岁儿童的上级类概念匹配操作有显著性影响,６岁儿童才摆脱了这种制约作用。

The readability of educational materials written for parents of children with attention-deficit hyperactivity disorder

Health-care providers are relying increasingly on printed materials to educate patients and their families about varous aspects of their health or mental health conditions. For the target audience to be able to read and understand health brochures, they should be written at or about the 8th-grade level and incorporate variables that facilitate comprehension. The purpose of this study was to analyze brochures related to Attention-Deficit Hyperactivity Disorder to determine (a) if they were written at a level appropriate for the target audience, and (b) the extent to which they incorporated variables identified in the research literature as facilitating comprehension. The results showed that the brochures were written at a reading level beyond that of the target audience. Further, although the brochures incorporated a large number of variables which facilitate comprehension, many were not used to the extent necessary to ensure that readers would be able to understand the brochures. These results clearly indicated the need for health care materials to be written in such a way that they can be read and understood by the target audience.     

The association between team‐level social capital and individual‐level work engagement: Differences between subtypes of social capital and the impact of intra‐team agreement

The study explored the association between team‐level social capital and individual‐level work engagement. Questionnaire data were collected from six companies in the dairy industry. Seven hundred seventy‐two participants divided into 65 teams were included. In confirmatory factor analyses, we found a superior model fit to a four dimensional model of social capital: bonding social capital, bridging social capital and two types of linking social capital. The results showed a positive association between all subtypes of social capital at the team level and work engagement at the individual level. However, this association only remained significant for linking social capital in relation the workplace as a whole when we adjusted for psychosocial working conditions. The level of intra‐team agreement in social capital score did not moderate the association between social capital and work engagement. In conclusion, the results provide further support for previous findings suggesting a positive association between social capital and work engagement. They add to the existing knowledge by suggesting that linking social capital in relation to the workplace is the most important explanatory variable for work engagement, thus emphasizing the need to distinguish between subtypes of social capital in research and practice.     

糖尿病与睡眠的相互关系

人一生中有1／3的时间在睡眠中度过,睡眠质量直接关系到一个人的身体健康。睡眠时间过少或过多的人糖尿病患病率大大增加。糖尿病本身的病理、生理特点,严重影响患者的睡眠质量,睡眠质量又可以反过来影响糖尿病患者的血糖水平。有研究显示,糖尿病患者最佳睡眠时间为8小时。同时糖尿病患者中睡眠呼吸暂停综合征（OSAS）患病率高,0SA...     

文本阅读中数量比较信息整合的过程与内容

引入数量比较信息,采用移动窗口阅读技术对文本阅读中推理的过程与内容进行研究。实验1探讨当文本阅读中存在数量比较信息时,是否能够进行即时整合,实验2和实验3分别探讨了数量比较信息即时整合的过程与内容。结果发现:当文本阅读中存在数量比较信息时,读者能够进行即时的信息整合,这种整合是自下而上的,支持记忆基础文本加工理论,如果时间足够,这种整合能够达到量化程度。
