The perseverance of numerical distance effect in attentional blink

In a number comparison task, it is easier to respond faster when the two numbers are further apart than when they are close. This inverse relationship between the size difference and the time to judge such difference is called the numerical distance effect (NDE). In this study we investigated whether attention plays a critical role in the surfacing of NDE and the way we process Arabic numbers. In experiments 1 and 2, with an attentional blink paradigm that was designed to modulate attention, we tested whether a limited or unlimited pool of attentional resources would have an impact on the performance and trend of NDE. The results showed a dissociable effect of attention that changed the overall accuracy but not the trend of NDE. In experiment 3 we examined whether the number priming effect, another phenomenon associated with the distance-related effect, would be affected during the attentional blink period. We found the pattern of number priming effect was not affected by attentional blink. An explanation of the role of attention in number distance processing, as well as how it interacts with Arabic number representation, is discussed.     

对骨折治疗"优化选择"与"合理选择"的理解和思考

从合理化角度回顾了当前几种重要的骨折治疗理论体系的发展与演变,认为骨折治疗的最优原则是一种理想状态,现实中没有绝对最优只有相对合理.只有建立以患者为中心的思维体系,加强医疗逻辑思维能力,用多维思考的方式寻找矛盾的合理平衡点,始终坚守医学伦理道德底线,才能真正做到为每一位骨折患者进行最合理的治疗.

Terror management among Taiwanese: Worldview defence or resigning to fate?

Terror management theory (TMT) proposes that people who are reminded of their mortality should be motivated to defend their cultural worldview. Studies 1 and 2 examined whether the TMT worldview defence‐buffering effect found in Western cultures could be generalized to Asians in Taiwan. No such effect was found in the present studies. This non‐significant result was robust when either a stronger distraction task was used (study 1) or when a subliminal manipulation of mortality salience was utilized (study 2). A meta‐analysis, including 24 TMT experiments in East Asia, was also conducted (study 3). The average effect size (d = 0.11, r = 0.055) of worldview defence among these experiments was not significantly different from zero. Study 4 found that mortality salience manipulation also did not change Taiwanese participants' view of reincarnation; however, it did make them more inclined to resign to fate, suggesting that they might be using this symbolic means to defend their anxiety of death. The issue of the generality of TMT to Asians was discussed.     

青少年网络成瘾人格特征研究

本研究采用问卷调查法,对某初级中学363名初中生的网络成瘾状况与人格特征进行研究。结论表明:初中生网络成瘾检出率为5.79%;初中生在网络成瘾存在性别差异,男生比女生更易成瘾。网络成瘾学生与非成瘾学生在《卡特尔十四种人格因素问题》中的忧虑性、自律性、适应性与焦虑性、孤独倾向、身体症状和冲动倾向等因子上差异显著。与非成瘾学生相比,成瘾学生的自制能力较差,成瘾学生可能更经常体验到孤独、焦虑和不满,并且在生活中较容易出现适应不良现象。     

面孔-词Stroop范式中的情绪冲突效应研究

为探究面孔-词Stroop范式中的情绪冲突效应,本实验给被试呈现两种时长（150ms或1500ms）的刺激,令其分别完成对面孔-词Stroop范式中的“面孔任务”和“词任务”。结果发现：只有“面孔任务”中出现Stroop效应,产生情绪冲突,而在“词任务”中未出现Stroop效应;当呈现时间为150ms时,情绪词影响情绪面孔加工从而引发个体的情绪冲突,出现Stroop效应;当呈现时间为1500ms时,“面孔任务”中的Stroop效应消失。这提示了呈现时间是影响面孔-词Stroop范式中情绪冲突效应的一个重要因素。     

45天-6°头低位卧床对个体额区EEG偏侧化和情绪的影响

考察了16名22~34岁男性被试在45天-6°头低位卧床模拟失重条件下, 在卧床前(第2天)、卧床期(第11, 20, 32, 40天)及卧床后(第8天)的额区EEG偏侧化变化趋势, 并采用贝克焦虑量表(BAI)和贝克抑郁量表(BDI)对主观情绪状态进行评估。研究发现EEG偏侧化指标呈现出明显的线性变化趋势。卧床期间个体的心境状态处于比较低的水平, 报告有较强的躯体焦虑感。在整个卧床期间, 个体为维持稳定的情绪状态而付出比较大的情绪调节努力。     

系统合理化何以形成——三种不同的解释视角

系统合理化理论认为, 人们会自然地将其所在的社会系统感知为公平合理的, 这一倾向即系统合理化。而系统合理化形成之原因, 一直是该领域理论和研究关注的重点。为此, 研究者先后提出了三种解释思路。认知失调视角认为, 系统合理化之所以产生是因为个体想要缓解因系统无法满足他们的需求而产生的焦虑。补偿性控制视角认为, 系统合理化源于个体自身控制感的缺乏。社会认知视角则认为人们固有的认知倾向特别是对于社会经济差异的内归因倾向是造成系统合理化的根源。未来可以考虑在同一个研究中包含来自于不同理论视角的解释变量, 借鉴相近领域的发现探索其他可能存在的系统合理化的形成机制, 探究中国文化特有的系统合理化的来源, 同时对积极的合理化与消极的合理化作出区分, 并在此基础上针对社会现实问题加强应用研究的开展。     

The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions.
