The National Research Council Report on the Prevention of Reading Difficulties in Young Children and the Process of Dubitation

The author examines two significant issues, the adjudication of evidence and the architecture of instruction in the context of research on beginning reading. In particular, he reflects on his participation as a member of the National Research Council's committee that published the recent report entitled Preventing Reading Difficulties in Young Children (1998). The National Academy of Sciences panel of experts process is contrasted with a more explicit process for codifying scientific evidence and including quantitative experimental research as the primary source of evidence. In addition, the author argues for the importance of attending to the architecture of instruction in beginning reading.     

Changing explanatory frameworks in the U.S. government’s attempt to define research misconduct

Nearly two decades of debate have not settled the definition of research misconduct. The literature provides four explanatory frameworks for misconduct. The paper examines these frameworks and maps them onto efforts by the U.S. Public Health Service to define research misconduct and subsequent responses to these efforts by the scientific community. The changing frameworks suggest that closure will not be achieved without an authoritative effort, which may occur through the Research Integrity Panel’s recent attempt to create a government-wide definition.     

大学生学习体验与学习结果的关系：学生投入的中介作用

选取3063名大学二年级本科生（平均年龄19.76 ± 0.73岁）为被试,考察大学生投入在学习体验（课堂学习体验和课外学习体验）和学习结果（学业成就、共通能力和学习满意度）间的中介作用。结果发现：（1）大学生投入在学习体验和学业成就间起部分中介作用;（2）大学生投入在学习体验和共通能力间起完全中介作用;（3）大学生投入在学习体验和满意度间起部分中介作用。     

The Stories We Tell: Introduction to the Special Issue on Ethical Challenges in Community Psychology Research and Practice

This Special Issue examines ethical challenges in community psychology research and practice. The literature on ethics in community psychology has remained largely abstract and aspirational, with few concrete examples and case studies, so the goal of this Special Issue was to expand our written discourse about ethical dilemmas in our field. In these articles, researchers and practitioners share stories of specific ethical challenges they faced and how they sought to resolve them. These first‐person narratives examine how ethical challenges come about, how community psychology values inform ethical decision making, and how lessons learned from these experiences can inform an ethical framework for community psychology.     

面孔吸引力观察者参照:“角度效应”的眼动研究

以标准的黑白面孔图片作为实验材料,让41名大学生观看不同倾斜角度(左倾、竖直和右倾)的面孔图片,并对之进行面孔吸引力的评价,同时用眼动仪记录被试的眼动数据。结果显示:(1)被试观看左倾和右倾面孔的平均瞳孔大小显著小于观看竖直面孔的平均瞳孔大小,观看左倾面孔的平均瞳孔大小显著大于右倾面孔;(2)被试对左倾和右倾面孔的平均注视时间显著短于对竖直面孔的平均注视时间,同时对左倾面孔的注视时间显著长于右倾面孔;(3)被试对左倾和右倾面孔的平均注视次数显著少于对竖直面孔的平均注视次数。实验结果表明,面孔的倾斜角度很可能是影响面孔吸引力的一个重要因素,在面孔吸引力的审美偏好中存在"角度效应",即竖直面孔的吸引力高于倾斜面孔的吸引力,左倾面孔的吸引力高于右倾面孔的吸引力。     

多时点结果跨期选择的决策效应及其心理机制

多时点结果跨期选择涉及两个及两个以上多个时点结果的权衡, 正日益成为跨期选择的研究重点。现有研究主要从两时点结果和序列结果两方面深入探讨了多时点结果跨期选择中的诸多决策效应, 包括：隐藏的零效应、象征效应、额外金额效应、前端金额效应以及序列效应, 并运用序列模型和权衡模型对上述决策效应进行阐释。未来还应深入探索同时涉及损益结果混合的多时点结果跨期选择, 运用决策过程追踪技术揭示决策效应的过程机制。
