Saints-protectors from Snake Bite: A Short Overview and a Tentative Analysis

A short overview of several saints, including Peter, Paul, John, George, Hilarius, Hubert, and Gaudentius, venerated in Christian tradition as protectors from snake bite, is offered as an introduction to a more substantial debate on the factors determining the choice of protectors in folk medicine, as well as on the possible adjuvant effect of (auto)suggestive therapy obtained by the invocation of saints.     

归因过程“背景效应假设”的初步实验研究

通过两个实验考证了归因过程的“背景效应假设”：实验1表明,当要求活动者和观察者采用同样的背景事件时．他们之间的归因差异消失了;实验2表明,当有其它的背景信息可供参考时,被试就不再完全按照Kelley所假定的一致性和区别性信息进行归因推断。     

老年原发性高血压晨峰现象与靶器官损害临床研究

应用24h动态血压监测(ABPM)了解老年原发性高血压晨峰现象对主要靶器官结构及功能的潜在损害。114例老年原发性高血压患者根据24h动态血压监测分为晨峰组和非晨峰组,均常规检查血脂谱,空腹血糖,放免法测定尿微量白蛋白,计算体重指数(BMI)、左室质量指数(LVMI)、颈总动脉(CCA-IMT)和颈内动脉内膜中层厚度(ICA-IMT)、心电图测量计算QT离散度(QTcd)。晨峰组的24h、白昼、夜间平均收缩压均显著高于非晨峰组动态血压监测水平(P<0.05),而且晨峰组的睡-谷晨峰变异幅度增高有统计学意义(P<0.05)。晨峰组的LVMI、CCA-IMT、ICA-IMT、QTcd和尿微量白蛋白指标均高于非晨峰组(P<0.01)。两组在BMI、血脂谱、血糖差异无统计学意义。清晨高血压是老年原发性高血压病的一个不可忽视的潜在危险因素。长期晨间血压负荷升高使得机体全天处于血压高负荷状态,更易使心肌重构肥厚和心电生理特征改变,增加心律失常发生率;加速动脉粥样硬化斑块形成。因此遏制老年原发性高血压患者的晨峰高反应是降压达标和减缓靶器官损害的关键环节。     

Searching for two categories of target in dynamic visual displays impairs monitoring ability

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in both contiguous and discrete spatial configurations. Response time (RT) and accuracy were recorded, and evidence of predictive monitoring was assessed via first fixations and refixations of target‐predictive stimuli. RTs to target onsets and evidence of predictive monitoring were reduced in dual‐target, relative to single‐target, conditions. Further, predictive monitoring did not speed RTs but was influenced by display configuration. In particular, discrete displays impaired monitoring for number targets in the dual‐target condition. Implications exist for real‐world visual tasks involving multiple target categories and for visual display design.
