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.     

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.     

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.     

过度自信的跨文化差异

过度自信是指个体过高地估计自身判断的精确度,其经典的研究范式是常识问题及常识问题的变式现实情境问题。使用常识问题的研究一致发现,东方人显著比西方人更过度自信;使用现实情景问题的研究则发现,西方人比东方人更过度自信或两者无显著性差异。对“东方人比西方人过度自信”的解释包括认知习惯和教育系统两种主流观点。最后对出现不同研究结果的原因进行讨论,并进一步探讨解释的有效性和“西方人比东方人过度自信”的原因。     

知识经验与顿悟：来自认知神经科学的证据

知识经验对于顿悟问题解决是一把双刃剑,强势知识会阻碍顿悟问题解决,弱势知识才是顿悟问题解决的关键。强势知识引导的组块效应、约束效应和固着效应等心理定势现象,“帮助”问题解决者以惯用方案来理解、思考和解决问题。之所以会这样,可能是因为大脑内存在一套具有优先级差的层级加工系统,赋予惯用方案的优先级最高。不过,惯用方案不仅不能够解决顿悟问题,而且还会通过注意竞争和注意失灵方式来阻碍新异方案的探索和执行,所以,问题解决者往往都会进入思维僵局。僵局的打破和顿悟的实现,需要抑制住强势知识及其相关的惯用方案、激活弱势知识和新异方案,这违反了大脑的认知加工惯性,是很难以自发发生的。但是,可以通过激活扩散来增强弱势知识的激活水平,或者是拓宽注意范围、提高注意灵活性来增加弱势知识激活的可能性,从而促进顿悟问题解决。     

Defining Creativity: Don't We Also Need to Define What Is Not Creative?

I argue that any attempt to define creative ideas cannot fully succeed without also defining uncreative ideas. This argument begins by defining three parameters that characterize a potentially creative thought: the idea's initial probability (p), the final utility (u), and the creator's prior knowledge of that utility (v). The three parameters then lead to a three‐criterion multiplicative definition of personal creativity, namely, c = (1 ? p)u(1 ? v), where the first factor indicates originality and the third factor surprise. Although creativity can only maximize as originality, utility, and surprise all approach unity, the same definition indicates that there are seven different ways that creativity can minimize. These alternatives were identified as (a) routine, reproductive, or habitual ideas, (b) fortuitous response bias, (c) irrational perseveration, (d) problem finding, (e) rational suppression, (f) irrational suppression, and (g) blissful ignorance. If the third parameter v is omitted, then the number of creative and noncreative outcomes reduces to just four, making creativity indistinguishable from irrational suppression. The alternative outcomes are then illustrated using the classic two‐string problem. Besides providing a more finely differentiated conception of creativity failures, the definition has critical implications regarding the processes and procedures required to generate highly creative ideas.     

Intact Procedural Knowledge in Patients with Alzheimer's Disease: Evidence from Golf Putting

Can Alzheimer's disease (AD) patients efficiently learn to perform a complex motor skill when relying on procedural knowledge? To address this question, the authors compared the golf-putting performance of AD patients, older adults, and younger adults in 2 different learning situations: one that promotes high error rates (thus increasing the reliance on declarative knowledge) or one that promotes low error rates (thus increasing the reliance on procedural knowledge). Motor performance was poorer overall for AD patients and older adults relative to younger adults in the high-error condition but equivalent between similar groups in the low-error condition. Also, AD patients in the low-error condition had better performance at the final putting distance relative to those in the high-error condition. This performance facilitation for AD patients likely stems from intact procedural knowledge.     

The Effects of Differing Knowledge Transfer Strategies on Group Decision Making and Performance

Encouraging reflection on one's existing knowledge in a group setting increases shared understanding, makes information available for problem solving, and makes it easier for members to show and to be shown the merit of others' preferences. However, it is also possible that attempting to constrain the process by which problem solvers manage this reflection process may prevent them from effectively tailoring their approach to different problems. The current research focuses on how the nature of different knowledge transfer strategies impacts problem solving processes and outcomes by examining manipulations of, or constraints to, problem solvers' approach to knowledge transfer. Participants were directed to generate associated knowledge in preparation for answering a series of estimation items, either in a group or individually. We found that groups using a shared reflection process (as opposed to reflecting at an individual member level) were able to give more weight to the inputs of their more expert members and that groups outperformed individuals. We discuss the process of promoting knowledge transfer in a group context relative to an individual context and relate this to the concept of task demonstrability.

Knowing Versus Caring: The Role of Affect and Cognition in Political Perceptions

This paper examines the importance of political knowledge in shaping accurate perceptions of the political world—specifically, how levels of general political knowledge influence the accuracy of specific political judgments, how those judgments might also be shaped by "wishful thinking," and how political knowledge attenuates the impact of wishful thinking on political judgments. Predictions of who would win the U.S. presidential election in 1984, 1988, 1992, and 1996, as surveyed in the National Election Studies conducted in those years, were used as a measure of the accuracy of political perceptions. Analysis of these data reveals that both political knowledge and wishful thinking are important determinants of the accuracy of people's perceptions; in addition, the impact of wishful thinking on perceptions is attenuated by political knowledge.
