The development of young infants' intuitions about support

Previous research has shown that 3-month-old infants, like adults, expect a box to be stable when it is in full contact with a platform, and to fall when it loses all contact with the platform. Do young infants also have expectations about what should happen when the box is only in partial contact with the platform? The present research was designed to address this question. In Experiment 1, 6.5-month-old infants saw two test events: a full-contact and a partial-contact test event. In both events, the infants watched the extended finger of a gloved hand push a box along the top of a platform. In the full-contact event, the box was pushed until its leading edge reached the end of the platform. In the partial-contact event, the box was pushed until only 15% or 70% of its bottom surface remained on the platform. The infants looked reliably longer at the partial-than at the full-contact event when 15%, but not 70%, of the box rested on the platform. These results suggested that the infants were able to judge how much contact was needed between the box and the platform for the box to be stable. A control condition provided evidence for this interpretation. In Experiment 2, 5.5- to 6-month-old infants were found to look equally at the full- and the partial-contact events, even when only 15% of the box's bottom surface remained on the platform. This result suggested that prior to 6.5 months of age infants perceive any amount of contact between the box and the platform to be sufficient to ensure the box's stability. Interpretations of this developmental sequence are considered in the Conclusion.     

Ernest Becker and the Psychology of Worldviews

Sheldon Solomon, Jeff Greenberg, and Tom Pyszczynski offer experimental confirmation for Ernest Becker's claim that the fear of death is a powerful unconscious motive producing polarized worldviews and scapegoating. Their suggestion that their findings also prove Sigmund Freud's theory of repression, with worldviews as its irrational products, is questionable, although Becker's own statements about worldviews as "illusions" seem to invite such interpretation. Their basic theory does not depend on this, however, and abandoning it would enable them to take better advantage of their finding that worldviews incorporating the values of rationality and tolerance tend to counteract polarization effects.     

Individuation and paideia

This article attempts to discover an important historical precedent for the concept of individuation in the idea of paideia , which today, mistakenly, is often understood to have been simply the form of 'education' practised in ancient Greece. Paideia , however, was not limited to the instruction of youth and was based on no fixed programmes. It was conceived as continuing throughout the life of the individual, and as a development of natural, in-born potential. Paideia articulated a notion of 'inner culture', or cultura animi , which has since receded from Western civilization, with its anti-psychological emphasis on progress, specialization and extra-version, and with its notion that a civilization's 'culture' is primarily defined by its social structures and material tools. Present-day interest in the Jungian concept of individuation can thus be seen as a return of the repressed. An analysis of the Telemachy - the opening cantos of the Odyssey - in which Odysseus' son, Telemachus, accomplishes his passage to adulthood, reveals the need for the realization of natural potential to be an innate and archetypal ideal. Homeric poetry is then seen to have furnished a unified canon for the whole human being, whereas the subsequent course of European civilization, starting with the Greek Sophists and an ever more specialized notion of philosophy, is seen to have fostered a unilateral mode of maturation. It is argued that nostalgia for paideia indirectly reasserts itself through the widespread cultural interest in the idea of individuation.

Effects of a physical education intervention programme for ninth-graders on physical activity-related health competence: Findings from the GEKOS cluster randomised controlled trial

The main purpose of this cluster randomised controlled trial was to investigate the effects of a physical education (PE) intervention programme combining theoretical and practical components on students' knowledge, skills, abilities and motivation related to competence for a healthy active lifestyle. The intervention used learning tasks to combine theory on health and physical fitness with either running/jumping activities or small-sided ball games and was compared to regular PE classes. Forty-eight PE classes were randomly assigned to intervention (IG-run, IG-game play; 27 classes) and control (CG-run, CG-game play; 21 classes) groups. Overall, 841 ninth-graders (51.1% girls, M_age = 14.20, SD = 0.51) were tested before and after the six-week intervention and in an eight-to-twelve-week follow-up. Students completed a health-related fitness knowledge test, questionnaires on control competence for physical training, health- and fitness-related interest and attitudes, and physical fitness tests. Regressions in structural equation models revealed positive treatment effects of the game play intervention on students' knowledge (β_StdY = 0.33, 99.6% CI [0.12, 0.55]) and control competence for physical training (β_StdY = 0.26, 99.6% CI [0.02, 0.50]) at the post-test. No significant effects were found at the follow-up test. Treatment effects were independent of gender. The results indicate the short-term effectiveness of learning tasks combining theory with ball games in order to develop knowledge and control competence for physical training in PE. Further studies have to clarify how to sustain effects over time and address students' physical fitness and health- and fitness-related interest and attitudes in interventions combining theory and practice.Trial registrationThis study was retrospectively registered with the German Clinical Trials Register (DRKS), DRKS-ID: DRKS00016349.     

Canadian athletes' perspectives of mental health care and the importance of clinicians' sport knowledge: A multi-method investigation

The purpose of this inquiry was to explore Canadian competitive athletes' perspectives on their mental health care experiences using a sequential multi-method design. The overarching aims of the study were to explore athletes' self-reported reasons for seeking mental health care, their awareness of their clinician's knowledge of sport, and the importance they placed on their clinician having knowledge of the sport context. A sequential mixed methods design was employed in which two studies were conducted to address these aims. In study one, 70 current and former Canadian athletes completed a short survey assessing basic demographics, athletes' reasons for seeking treatment, and the importance they placed on their clinician having sport knowledge for effective care. In study two, ten athletes participated in individual semi-structured interviews in which similar topics were explored. Fifty-six percent of surveyed athletes reported that their clinicians' knowledge of sport did not impact their treatment experience, however only 29% reported being aware of their clinician having such knowledge. Thematic analysis of the interview data suggested that the connectedness of athletes' mental health issues and sport participation played a role in the importance they placed on their clinician having sport knowledge. Key components of a successful therapeutic alliance included the clinician validating the importance of sport, normalizing athlete mental health challenges, and understanding the demands of the competitive sport culture. Conclusions of this inquiry include that assessing how inter-related an athlete perceives their mental health challenges and sport participation to be, and demonstrating an understanding of the importance of sport in competitive athletes' lives, are likely helpful strategies in working clinically with this population even if a clinician does not have specific experience with the sport context.     

先前知识和样例设计对学习分数乘法规则的影响

研究通过3个实验,以6年级学生为被试,考察了先前知识在分数乘法规则单、双内容样例学习中的作用以及“标记法”、“标记+注释法”样例设计方法对低先前知识学生学习双内容样例的促进效果。结果发现：（1）高先前知识学生学习两种样例的迁移成绩无显著差异,且均好于低先前知识学生的成绩;（2）低先前知识学生学习单内容样例的迁移成绩明显优于双内容样例;（3）与学习普通样例相比,低先前知识学生学习“标记法”双内容样例的后测成绩无显著差异,但学习“标记+注释法”设计的样例的成绩明显更好。结果表明,学生单、双内容样例的学习效果受其先前知识水平的影响;低先前知识学生未能从“标记法”设计的双内容样例中获益,但学习“标记+注释法”设计的样例效果更佳。     

SCIENCE AND RELIGION: AN ORIGINS STORY

In recent scholarship, the science and religion debate has been historicized, revealing the novelty of the concepts of science and religion and their complex connections to secularization and the birth of modernity. This article situates this historicist turn in the history of philosophy and its connections to theology and Scripture, showing that the science and religion concept derives from philosophy's earlier tension with theology as it became an academic discipline centered in the medieval, then research university, with the centrality of Scripture changing under the influence of historical criticism. Looking at Thomas Aquinas and Friedrich Schleiermacher on theology and Scripture's connection to science, it offers a new framework for theorizing science and religion as part of the history of philosophy.     

EAST ASIA AND HUMAN KNOWLEDGE—A PERSONAL QUEST

This essay is a reflection on the ways we understand East Asia, as well as how East Asia is related to our knowledge construction. In spite of the personal tone, which I use strategically to formulate arguments in a carefully designed narrative flow, the article remains critical throughout and its conclusion is clear: exploration of the essence of East Asian civilization can constitute a meaningful effort to reevaluate and even restructure our current world of knowledge.
