Belief in altruistic human nature and prosocial behavior: a serial mediation analysis

According to the theory of internal working model, belief in altruistic human nature positively influences prosocial behavior. However, the precise influencing mechanism remains unclear. Based on the determinants of human behavior theory and self-efficacy theory, we hypothesized that belief in altruistic human nature indirectly influences prosocial behavior through causally linked multiple mediators of prosocial attitude and prosocial self-efficacy. The results of the current research supported our hypothesis and demonstrated that this serial mediation model could be generalized across individualistic and collectivistic cultures.     

依恋焦虑对大学生囤积行为的影响:无法忍受不确定性与经验性回避的序列中介作用

为探讨依恋焦虑、无法忍受不确定性、经验性回避与大学生囤积行为的关系，本研究构建了一个序列中介模型。采用问卷法对黑龙江等地高校的610名大学生进行调查研究。结果发现：（1）无法忍受不确定性和经验性回避在依恋焦虑与大学生囤积行为之间均起部分中介作用；（2）无法忍受不确定性和经验性回避在依恋焦虑和大学生囤积行为之间构成序列中介，即依恋焦虑个体通过增强无法忍受不确定性，从而提高经验性回避倾向，进而增加大学生的囤积行为。研究进一步从认知和应对手段角度来考察依恋焦虑对大学生囤积行为的作用机制，对囤积行为的预防和干预具有启示意义。     

Do better stories make better memories? Narrative quality and memory accuracy in preschool children

The present study examines how the quality of children's narratives relates to the accuracy of those narratives. Sixty‐one 3‐ to 5‐year‐olds played a novel game with a researcher in their schools. Children were questioned in an interview that included an open‐ended free recall prompt followed by a series of directed questions. Children's narratives were coded for volume, complexity and cohesion as well as for accuracy. Correlational results showed that overall, narrative skills enable the reporting of more information, while decreasing the proportion of information that was accurate. These results appeared to be driven by a quantity‐accuracy trade‐off; in an ensuing regression analysis with all narrative variables entered into the model, volume was associated with decreases in accuracy while narrative cohesion was associated with increases in accuracy. We discuss the results in terms of their relationship to the development of autobiographical memory as well as implications for forensic contexts. Copyright © 2007 John Wiley & Sons, Ltd.     

Looking at the past through a telescope: adults postdated their earliest childhood memories

ABSTRACT

Our previous studies have consistently shown a telescoping error in children’s dating of earliest childhood memories. Preschool children through adolescents systematically date their earliest memories at older ages, in comparison with the age estimates provided by their parents or by themselves previously. In the current study, we examined the dating of earliest childhood memories in two samples of college adults and collected independent age estimates from their parents. Consistent with our findings with children, adults significantly postdated their earlier memories by approximately 12 months (Study 1) and 6 months (Study 2). The actual age of earliest memories was 2.5 years after adjusted for telescoping errors, 1 year earlier than what is commonly believed at 3.5 years. These findings challenge commonly held theoretical assumptions about childhood amnesia and highlight critical methodological issues in the study of childhood memory.     

Log Data Analysis with ANFIS: A Fuzzy Neural Network Approach

This study explores the use of the Adaptive Neuro-Fuzzy Inference System (ANFIS), a neuro-fuzzy approach, to analyze the log data of technology-based assessments to extract relevant features of student problem-solving processes, and develop and refine a set of fuzzy logic rules that could be used to interpret student performance. The log data that record student response processes while solving a science simulation task were analyzed with ANFIS. Results indicate the ANFIS analysis could generate and refine a set of fuzzy rules that shed lights on the process of how students solve the simulation task. We conclude the article by discussing the advantages of combining human judgments with the learning capacity of ANFIS for log data analysis and outlining the limitations of the current study and areas of future research.     

教学条件下中学生物学概念形成的实验研究

本实验借助假设检验模型对学生在习得条件下生物学概念形成过程进行探究,实验结果表明:1、学生生物学概念的形成存在高起点、缓增长、平台振荡的特点,没有突破现象;2、探究教学更有利于概念的形成.尤其利于发掘学生后程的学习潜力;3、学生对概念的掌握可能存在一个统计学意义上的阈值,相同条件下探究教学比讲授法较更利于学生达到该阈值.
