A Historical Overview of Liberation Theology Some Implications for the Christian Educator

What is it about the language of liberation theology that can inform and enrich our understanding of curriculum, leading to a pedagogical practice of hope and liberation? To understand that question, we must have an appreciation and realization of the historical roots of how liberation theology unfolded in the course of history in Latin America. To that end, this article gives a historical overview of the circumstances that led to the language and action of liberation theology. The article discusses how the theological praxis of liberation theology can inform the Christian educator, particularly when working with the poor.     

论数学问题解决的生态模式

随着教育学和心理学生态化研究的兴起,以及数学教育改革的理论发展与实践诉求,从生态观的角度来审视数学问题解决具有重要的理论意义和实践价值。文章以数学问题解决的生态观为基础,从理论上构建了一个关于数学问题解决的生态模式,并论述了该生态模式的5个内部系统(即,数学文化、数学问题、数学知识、问题解决者和问题解决程序)的相互关系及其作用机制。     

Everyday Problem Solving and Emotion: An Adult Developmental Perspective

ABSTRACT— Despite cognitive declines that occur with aging, older adults solve emotionally salient and interpersonal problems in more effective ways than young adults do. I review evidence suggesting that older adults (a) tailor their strategies to the contextual features of the problem and (b) effectively use a combination of instrumental and emotion-regulation strategies. I identify factors of problem-solving contexts that affect what types of problem-solving strategies will be effective. Finally, I discuss how this identification of factors affects what we know about developmental differences in everyday problem-solving competence.     

Marijuana: A Review of Medical Research With Implications for Adolescents

Recent medical evidence indicates that marijuana is more harmful than had previously been suspected. A review of recent research in the following areas is presented: tolerance and persistence, reproductive system, respiratory system, immune system, central nervous system, genetic and chromosomal effects, and behavioral effects. Implications for mental health professionals are discussed.     

Evidence-Based Ethical Problem Solving: An Idea Whose Time Has Come

This is an account of the evolution of ideas and the confluence of support and vision that has eventuated in the founding of the Journal of Empirical Research on Human Research Ethics (JERHRE). Many factors have contributed to the creation of this rather atypical academic journal, including a scientific and administrative culture that finally saw the need for it, modern electronic technology, individuals across the world who were committed to somehow finding common ground between researchers and those charged with ethical oversight of research, a network of helpful colleagues, and a university whose administration gave moral support to the endeavor in a time of fiscal austerity. Perhaps equally important were the decisions to make JERHRE a nonprofit undertaking, to emphasize the implications of empirical research for specific best practices, to serve the educational needs of those concerned with human research, and to seek to stimulate the interest of students in gaining an evidence-based understanding of the research contexts in which they decide to work. This article explores the ‘chemistry’ that has made it possible to develop a somewhat unorthodox journal and set of related activities.     

Research Integration for Psychologists: An Overview of Approaches1

This article encourages psychologists to learn about and apply nontraditional (quantitative) approaches to research integration. Various research integration approaches (literary, vote-counting, combining significance levels, and meta-analytic) are summarized. Also discussed are the advantages of meta-analytic approaches to research integration and some of the problems posed by the use of such quantitative procedures. Implications for psychology include more complete reporting of research results, integration of research in areas of interest to psychologists, and identification of research gaps.

Cognitive Abilities Involved in Insight Problem Solving: An Individual Differences Model

This study investigated individual differences in cognitive abilities that contribute to solving insight problems. A model is proposed describing three types of cognitive ability that contribute independently to insight: convergent thinking, divergent thinking, and breaking frame. The model was tested in a large sample (N = 108) by regressing insight problem solving performance on measures of these three abilities. This analysis demonstrated that all three abilities predicted insight independently. Convergent thinking was further broken down into verbal intelligence and working memory, which also predicted insight independently of each other and of divergent thinking and breaking frame. Finally, when pitted against noninsight problem solving as a predictor in regression, only insight problem solving was uniquely associated with divergent thinking and breaking frame. The model is suggested as a potentially useful taxonomy for the study of ill-defined problems and cognitive abilities.     

An Evaluation of Interventions to Facilitate Algebra Problem Solving

Three participants were trained on 6 target algebra skills and subsequently received a series of 5 instructional interventions (cumulative practice, tiered feedback, feedback plus solution sequence instruction, review practice, and transfer training) in a multiple baseline across skills design. The effects of the interventions on the performance of 5 problem-solving tasks that required novel combinations of 2 or more of the target skills were evaluated. Results showed that cumulative practice of the skills and a combination of feedback with solution sequence instruction led to limited performance increases on some of the problem-solving tasks, with one task meeting the mastery criterion following the solution sequence intervention. The introduction of the transfer training resulted in more consistent improvements across tasks such that participants achieved the performance criterion on all remaining problem-solving tasks during a final baseline condition. The findings suggest that a structured intervention designed to transfer stimulus control from previously established discriminative stimuli to more complex, novel stimuli can facilitate problem solving without extensive direct instruction on the higher-level skills.

Gender Research in Spanish Psychology: An Overview for International Readers

In the last decades, many political and socioeconomic transformations occurred in Western countries with a considerable impact on gender equality. In this special issue, we aim to show how these transformations can generate changes in gender research by presenting Spain as an example of remarkable growth in gender studies, following the intense societal advancement of the country toward gender equality policies. In particular, we examine the evolution of gender research in Spain analyzing the presence of Spanish gender research in international journals, national journals, book reviews, and conferences. This first volume also includes a presentation of several original studies covering three specific research areas: gender stereotypes, gender violence, and gender issues at work. Finally, we discuss how the unique socioeconomic scenario created in this country may serve for international readers and gender researchers.     

Herbaceuticals: An Overview for Counselors

As more and more people are using unregulated herbaceuticals worldwide, counselors need to be alert to the types of herbs clients may be taking; the effects, side effects, and drug interactions associated with different herbaceuticals; and the ethical implications of treating a client who is taking herbaceuticals. This article provides an overview of the psychological, physiological, cultural, and legal issues associated with herbaceuticals and introduces some of the emerging ethical issues.     

顿悟问题思维僵局早期觉察的脑电研究

思维僵局不仅是顿悟问题有别于常规问题的重要要素, 而且是顿悟赖以实现的基础。先前研究虽对顿悟瞬间的脑认知活动进行了较充分的探讨, 但却较少对思维僵局的有关过程进行研究。思维僵局究竟是源于早期的知觉阶段还是晚期的问题加工阶段至今仍是未解之谜, 但它却是人们认识顿悟过程所必需的。只有充分认识和理解了该过程, 才可能更全面地理解顿悟究竟建立在怎样的脑认知表征的基础之上。研究运用ERPs技术, 采用猜谜任务范式对顿悟中思维僵局产生的阶段及其脑认知活动进行了探讨。研究发现, 在120~210 ms和620~800 ms内, “有僵局”谜题较之“无僵局”谜题在额-中央区分别诱发了一个更正的P170和晚期LPC。其中, P170主要反映人脑对思维僵局的早期觉察, LPC则主要表征人脑经过一定解题尝试后对前期预评估僵局的修正和有意识反思。这些结果挑战了传统的思维僵局的晚期产生假说, 支持思维僵局的“早期产生机制”假说, 表明人脑在早期知觉阶段就能直觉地觉察思维僵局的存在。     

问题解决策略的元认知研究

本研究旨在了解大学生对问题解决策略的理解。通过测试57名大学生对五种问题解决策略(自由产生、类推、逐步分析、形象化重构和整合)在三种情景(人际交往、实际生活和学习过程)三个维度(经常使用、有效性、易于使用)下的评估,发现大学生使用类推策略最多,自由产生策略最少。他们普遍认为这五种策略最适宜于用在学习情景中,在人际交往中的用处不大。这种结果在性别上没有显著性差异。另外．大学生认为几乎每一种策略都需要综合、分析、判断和推理四种思维能力,其中自由产生策略需要用到更多的能力,包括创造能力。     

Gender Differences in Problem Solving: Expectancy and Problem Context

In this study, we investigated gender differences in problem solving as a function of problem context and expectations for success. Subjects were 90 women and 56 men from introductory psychology classes who were administered a set of mathematical problems varying in gender context under male-expectancy, female-expectancy, and neutral-expectancy conditions. No significant gender differences or interaction of gender with problem context were found. However, significant effects of problem context and expectancy were found. Both male and female subjects made higher scores on female-context problems and lower scores in the female-expectancy condition. When mathematics aptitude was used as a covariate, an interaction of gender with expectancy was found. Men in the female-expectancy condition made significantly lower scores than either men or women in the male-expectancy condition.
