风险决策和跨期决策的过程比较：以确定效应和即刻效应为例

风险决策和跨期决策与人类生存发展密切相关, 且两类决策在理论发展、行为效应及神经基础等方面具有相似性。为检验二者是否具有共同过程机制, 本研究以风险决策中的确定效应和跨期决策中的即刻效应为例, 采用眼动追踪技术比较了它们的局部、整体过程及模型拟合。辅以贝叶斯因子分析实验数据表明：二者的主要过程特征均相似, 且更符合非折扣模型假设; 二者在加工复杂程度等少数特征上有所不同; 确定和即刻信息在加工方向等特征上存在特异性。这表明二者可能具有共同的核心决策规则：两类决策更可能遵循非折扣模型预期的简捷、启发式规则, 而不是折扣模型所假设的补偿性、基于选项规则。本研究为建立两类决策的共同解释框架做出了有益尝试, 并为决策比较研究方法提供新的方向。     

教学设计中的成绩表现和心流体验:基于认知负荷视角

教学设计是为优化教学效果而形成的教学实施方案。为提高学习表现,认知负荷理论认为在组织教学设计时需考虑内、外认知负荷两大因素,但少有研究关注学生在学习过程中的体验。本研究通过单词复合性操纵内在负荷,通过呈现方式操纵外在负荷,探究两类负荷对心流体验及表现的影响。结果发现,内在负荷对心流及表现均有影响,外在负荷仅在低水平组表现出对心流及表现的影响,另外内外负荷在低水平组的表现上存在交互作用。结果表明,教学设计中的内在负荷是影响心流及表现的稳定因素,外在负荷不仅受知识水平影响,其对表现的有效性还受内在负荷的调节。     

Socioeconomic and sociocultural determinants of psychological distress and quality of life among patients with psoriasis in a selected multi-ethnic Malaysian population

Patients with psoriasis may have increased risk of psychological comorbidities. This cross-sectional study aimed at determining associations between sociocultural and socioeconomic factors with the Depression Anxiety Stress Scale (DASS) scores and the Dermatology Life Quality Index (DLQI) scores. Adult patients with psoriasis were recruited from a Dermatology outpatient clinic via convenience sampling. Interviews were conducted regarding socio-demographic factors and willing subjects were requested to complete the DASS and DLQI questionnaires. The Pearson χ² test, Fisher’s exact test and multivariate logistic regression were used for statistical analysis to determine independent predictors of depression, anxiety, stress and severe impairment of quality of life. Unadjusted analysis revealed that depression was associated with Indian ethnicity (p = .041) and severe impairment of quality of life was associated with Indian ethnicity (p = .032), higher education (p = .013), higher income (p = .042), and employment status (p = .014). Multivariate analysis revealed that Indian ethnicity was a predictor of depression (p = .024). For stress, tertiary level of education (p = .020) was an independent risk factor while a higher monthly income was a protective factor (p = .042). The ethnic Indians and Malays were significantly more likely than the ethnic Chinese to suffer reduced quality of life (p = .001 and p = .006 respectively) and subjects with tertiary education were more likely to have severe impairment of quality of life (p = .002). Our study was unique in determining sociocultural influences on psychological complications of psoriasis in a South East Asian population. This has provided invaluable insight into factors predictive of adverse effects of psoriasis on psychological distress and quality of life in our patient population. Future studies should devise interventions to specifically target at risk groups in the development of strategies to reduce morbidity associated with psoriasis.     

Putting It on the Line: Telephone Counseling for Adolescent Smokers

Adolescent smokers need cessation help, but the question of how best to intervene remains unanswered. This article describes the empirically validated protocol of an established, well‐utilized adolescent telephone counseling program for smoking cessation, tailored to adolescent developmental needs and shown to increase clients' 6‐month prolonged abstinence rate significantly. Clinical issues addressed include client assessment, motivation, self‐efficacy, familial and social support, planning, coping, relapse‐sensitive call scheduling, and self‐image. Counselor training considerations are also discussed.     

大学生弱势群体的伦理社会处境分析与思考

随着高校招生规模的不断扩大,大学生中弱势群体的绝对数量也大大增加,成为高校必须正视、重视和关注的特殊群体.从共性角度对这一特殊群体面临的两大伦理困境:挫折感强和社会认同感弱进行了深层解析;从类特性的角度对其他伦理问题进行了有益的探究和思考.     

学习者生成图解对说明文阅读理解和应用的效果

在112名大学生被试阅读难度不同的两种材料并解答相关的理解题和应用题时,按照阅读时是否要求生成图解与答题时是否允许生成图解两个条件将他们平均分为四个小组,探讨阅读画图与答题画图对被试理解和应用不同难度材料的影响。结果表明,阅读时学习者生成的图解可显著促进对难度较高材料的理解;答题时学习者生成的图解可显著促进对难度较低材料的应用;阅读时是否画图与答题时是否画图对理解和应用所学习材料没有显著交互作用。     

重新构建先天性心脏病的学科新模式

现有先天性心脏病防治模式存在明显不足.为了更加有利于患者的治疗及先心病的学科发展,建议重新构建先心病学科新模式,将先心病独立成科,内外科融为一体,使先心病学科向专业化发展.     

Are people always more risk averse after disasters? Surveys after a heavy snow‐hit and a major earthquake in China in 2008

China suffered both a heavy snow‐hit and a major earthquake in 2008. To investigate the effects of disasters on risky decision making, opportunity samples were obtained by recruiting residents in both devastated and non‐devastated areas. In a survey (Study 1) conducted shortly after the heavy snow‐hit, we found that people were not always more risk averse after a disaster as previous studies had claimed and that they were inclined to approach an option with ‘low probability associated gain’ and to avoid an option with ‘low probability associated loss’. These findings were replicated in a consecutive survey (Study 2) conducted after the Wenchuan earthquake. It was further found that the popularity of both insurance and lottery, which presumably contributed to overweighing of small probabilities, was detected to have been enhanced with substantial exposure to the earthquake disaster. The implications of these findings for risk education and government policy making were discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

天水“卦台山”与伏羲易学文化——从人文地理学和民俗学视角的探讨

天水市三阳川的卦台山是伏羲“仰观俯察”观物取象(则之)和创造原始易学的历史缩影.由于后人的不断附会,卦台山被人格化,周围的山、水和村庄被赋予了生命,三阳川卦台山下的十二村庄和二十四个自然村也被喻为十二生肖和二十四节气,从而构成了一幅美妙的原始天象(文)图.《周易》作为中华民族的源头文化,在天水时空上的重合,表明《周易·系辞下》所说伏羲”仰观天文,俯察地理”而画八卦的描述以及史书记载的伏羲诞生于成纪(天水)并不是空穴来风,应该是历史因子、口传史和实物的契合.     

当代农民工感知社会支持、自尊和主观幸福感的关系

本研究以600名农民工为被试,采用自编的农民工感知社会支持情景问卷以及修订的自尊量表、农民工主观幸福感问卷,以探讨农民工感知社会支持、自尊与主观幸福感的关系,并考查农民工自尊在其感知社会支持与主观幸福感之间的中介作用。结果表明：（1）高自尊水平农民工的主观幸福感及其各维度、感知社会支持都极其显著地高于低自尊农民工;（2）自尊水平与主观幸福感及各维度、感知社会支持水平之间存在极其显著的正相关关系;（3）感知社会支持、自尊与主观幸福感显著两两正相关;（4）自尊在感知社会支持基础上对主观幸福感及两个维度回归效应显著,为二者之间重要的中介变量。
