What is behind the priority heuristic? A mathematical analysis and comment on Brandstätter, Gigerenzer, and Hertwig (2006)

Comments on the article by E. Brandst?tter, G. Gigerenzer, and R. Hertwig. The authors discuss the priority heuristic, a recent model for decisions under risk. They reanalyze the experimental validity of this approach and discuss how these results compare with cumulative prospect theory, the currently most established model in behavioral economics. They also discuss how general models for decisions under risk based on a heuristic approach can be understood mathematically to gain some insight in their limitations. They finally consider whether the priority heuristic model can lead to some understanding of the decision process of individuals or whether it is better seen as an as-if model.

关于恶性肿瘤发病年轻化的思考

恶性肿瘤的发病多在50岁以后,以中老年人常见。近年发现青年(≤40岁)患癌有增高趋势。从恶性肿瘤的高危因素及分子机制方面,探讨恶性肿瘤发病年轻化的可能原因。辩证地剖析机体内部和外界环境之间的关系,是研究恶性肿瘤发病年轻化的重要环节。     

倦怠问卷(BM)的结构研究

为了考察BM问卷在中国文化背景下的适应性,用修订的倦怠问卷(BM)和中文版的MBI-GS量表对363名中小学教师进行施测。探索性因素分析和验证性因素分析的结果表明在中国文化背景下,三因素模型得到最优拟合,分别命名为耗竭、士气消沉、动机丧失;BM问卷的内部一致性系数在0.7999-0.8768之间,区分效度和聚合效度在0.762-0.259之间,均达到了心理测量学的要求。     

Using eye-tracking to study audio-visual perceptual integration

Perceptual integration of audio-visual stimuli is fundamental to our everyday conscious experience. Eye-movement analysis may be a suitable tool for studying such integration, since eye movements respond to auditory as well as visual input. Previous studies have shown that additional auditory cues in visual-search tasks can guide eye movements more efficiently and reduce their latency. However, these auditory cues were task-relevant since they indicated the target position and onset time. Therefore, the observed effects may have been due to subjects using the cues as additional information to maximize their performance, without perceptually integrating them with the visual displays. Here, we combine a visual-tracking task with a continuous, task-irrelevant sound from a stationary source to demonstrate that audio-visual perceptual integration affects low-level oculomotor mechanisms. Auditory stimuli of constant, increasing, or decreasing pitch were presented. All sound categories induced more smooth-pursuit eye movement than silence, with the greatest effect occurring with stimuli of increasing pitch. A possible explanation is that integration of the visual scene with continuous sound creates the perception of continuous visual motion. Increasing pitch may amplify this effect through its common association with accelerating motion.     

勒维纳斯和利科的伦理学的异同

法国现代哲学把伦理学作为一个核心问题。在现象学的框架之下,勒维纳斯和利科重新思考了主体的自由及其责任。该文简单地介绍这两位哲学家的基本观念。勒维纳斯比较强调个人对他人的无限伦理责任,而利科更强调美德,把它当作为伦理生活的出发点。虽然这些伦理立场不同而很难协调,可是它们都提供很必要的资源来思考现代伦理生活所面的困境和它的未来的可能。     

藏传佛教文化对藏药的影响

藏族宗教文化对藏药的影响是深远的,处于特殊地域环境及浓郁宗教文化氛围中的藏药,从它的用药思想,到其理论体系的形成,再到具体的临床实践过程,都无不渗透着藏族宗教文化的影子.其中重视"天人合一"的思想理念贯穿在藏药用药规律的始终,同时这一理念也引发我们对人与环境之间和谐统一关系的重新审视与思考.

先苦后乐:英语乐学大学生在英语学习时情绪反应的脑认知特点

运用功能性磁共振成像(fMRI)技术探索了乐学英语的大学生在对中、英文材料的学习、记忆及成绩反馈过程中的情绪和脑活动特征。结果发现,被试学习英文较之学习中文积极情绪更少且伴随更强的前部脑岛的激活;但当他们获得关于英文成绩的正反馈时,中脑奖赏区的激活却明显高于获得中文成绩正反馈时的情形,且中脑激活与英语乐学呈正相关。这说明乐学是"苦中作乐",人们虽在学习时并未体验到更多快乐,但其成功却带来了更大的心理奖赏。     

我国贫困大学生心理健康变迁的横断历史研究:1998~2015

为探讨自1999年高校国家助学贷款政策出台以来,我国贫困大学生心理健康状况的变迁,本研究对106篇1998至2015年间采用SCL-90量表的研究进行了横断历史元分析,考察了贫困大学生心理健康状况随年代的变化趋势。结果表明：（1）SCL-90量表中9个因子的分数均值均与年代呈负相关,年代对各因子变异的解释在4%至16%之间;1998年到2015年这18年来,各因子均值平均下降范围（效果量d）在0.24至0.55个标准差之间,其中强迫、抑郁和精神病3个因子均值变化尤为明显。这表明贫困大学生整体心理健康的状况在缓慢提升。（2）与中部地区相比,东部和西部地区贫困大学生心理健康水平18年来提高更明显。（3）虽然不同性别贫困大学生各因子历年变化差异并不明显,但女生抑郁和精神病两方面改善略快。此外,普通元分析结果表明总体上贫困男大学生比女大学生心理健康状况要好。
