运动员情绪调节心率变异性的影响因素

以183名运动员为被试,以心率变异性为指标,考察不同情绪状态、不同情绪调节策略下运动员自主神经反应的性别、运动年限、运动等级特点。结果发现：（1）快乐情绪状态下的心率变异性显著高于悲伤情绪状态下;表达抑制的心率变异性显著高于认知重评;短运动年限运动员的心率变异性显著高于长运动年限运动员;男性运动员的心率变异性显著高于女性运动员。（2）在快乐情绪状态下采用表达抑制策略时,低运动等级运动员的心率变异性显著高于高运动等级运动员;在悲伤情绪状态下,高运动等级运动员采用表达抑制策略比认知重评策略产生更高的心率变异性     

从思辨理性局限性看待中西医之争

中西医之争自西医进入中国以来不曾停止,分析解决此争执须从哲学入手。康德哲学首创将知性与理性区分,提出思辨理性超越经验的界限将产生二律背反,这种超越在各种旷日持久的大争论中经常出现,中西医之争是典型代表,而实践理性可化解此矛盾。思辨理性的局限性还表现在中医内部,中医学和中药学发展过程中都曾受到超越经验界限的思辨的影响,其中阴阳家和儒家学说表现较为突出,一定程度上阻碍了中医学发展。中医学早期在实践当中形成,现在需要也正在以新的实践方式发展,而无意义的中西医思辨理性之争应当抛弃。

     

从古今医学观论昼寝与身心健康

昼寝,最早出自于《论语》的“宰予昼寝”,谓当昼而寐,即意为日间小憩。中医学非常肯定睡眠的作用, 昼寝的传统中医理论包括阴阳睡眠学说、营卫睡眠学说和神主睡眠学说。结合目前的研究证据从心理和生理两方面概述了昼寝对人体健康的影响。昼寝在心理层面能改善主观的困倦和疲劳程度,还能改善认知能力和记忆能力,提高注意力、警觉性。在生理层面,昼寝与否及昼寝时长与一些心脑血管疾病、内分泌疾病、呼吸系统疾病患病风险密切相关。研究发现昼寝对人体健康的影响存在两面性,应根据身体状态、作息习惯等因人制宜。

     

Just Annexation

Fabre defends a human rights‐focused cosmopolitan theory of peace. One would expect that, given this view, she would be in favour of human rights‐promoting annexations by liberal states. However, she distances herself from this view, adopting the common‐sense view that annexing states ‘act ultra vires’. I argue that her core cosmopolitan view motivates a different and, in principle, much more positive view of four types of annexations. In the course of defending this view, I take a critical look at her appeal to perverse moral incentives and the notion of a cosmopolitan ethos.     

Kierkegaard on Existential Kenosis and the Power of the Image: Fear and Trembling and Practice in Christianity

What is the role of the image in faith? How should we relate to Abraham and Christ? Through new readings of two of Kierkegaard’s rarely compared texts, this article locates the religious power of the image in its ability to cleanse the subject of received mis‐images of Christianity, and suggests that Kierkegaard was inspired by elements of Rheno‐Flemish mysticism. Kierkegaard not only identifies this inward existential kenosis as the correct form of imitation, he narratively induces this in his reader. As well as examining this textual performativity and the imagination’s role of kenotically preparing the subject for her subsequent upbuilding, this article identifies the movement of kenosis as constitutive of faith – a task that involves suffering, but a suffering that is always accompanied and tempered by love.     

Contextual Integration in Multiparty Audience Design

Communicating with multiple addressees poses a problem for speakers: Each addressee necessarily comes to the conversation with a different perspective—different knowledge, different beliefs, and a distinct physical context. Despite the ubiquity of multiparty conversation in everyday life, little is known about the processes by which speakers design language in multiparty conversation. While prior evidence demonstrates that speakers design utterances to accommodate addressee knowledge in multiparty conversation, it is unknown if and how speakers encode and combine different types of perspective information. Here we test whether speakers encode the perspective of multiple addressees, and then simultaneously consider their knowledge and physical context during referential design in a three‐party conversation. Analyses of referential form—expression length, disfluency, and elaboration rate—in an interactive multiparty conversation demonstrate that speakers do take into consideration both addressee knowledge and physical context when designing utterances, consistent with a knowledge‐scene integration view. These findings point to an audience design process that takes as input multiple types of representations about the perspectives of multiple addressees, and that bases the informational content of the to‐be‐designed utterance on a combination of the perspectives of the intended addressees.     

Self‐Priming in Production: Evidence for a Hybrid Model of Syntactic Priming

Syntactic priming in language production is the increased likelihood of using a recently encountered syntactic structure. In this paper, we examine two theories of why speakers can be primed: error‐driven learning accounts (Bock, Dell, Chang, & Onishi, 2007; Chang, Dell, & Bock, 2006) and activation‐based accounts (Pickering & Branigan, 1999; Reitter, Keller, & Moore, 2011). Both theories predict that speakers should be primed by the syntactic choices of others, but only activation‐based accounts predict that speakers should be able to prime themselves. Here we test whether speakers can be primed by their own productions in three behavioral experiments and find evidence of structural persistence following both comprehension and speakers’ own productions. We also find that comprehension‐based priming effects are larger for rarer syntactic structures than for more common ones, which is most consistent with error‐driven accounts. Because neither error‐driven accounts nor activation‐based accounts fully explain the data, we propose a hybrid model.     

Cognitive Offloading: Structuring the Environment to Improve Children's Working Memory Task Performance

Research has shown that adults can engage in cognitive offloading, whereby internal processes are offloaded onto the environment to help task performance. Here, we investigate an application of this approach with children, in particular children with poor working memory. Participants were required to remember and recall sequences of colors by placing colored blocks in the correct serial order. In one condition the blocks were arranged to facilitate cognitive offloading (i.e., grouped by color), whereas in the other condition they were arranged randomly. Across two experiments (total N = 166) the ordered condition improved task performance for children with low working memory ability. In addition, participants in Experiment 2 rated the difficulty of the two arrangements and performed a further condition in which they were given an opportunity to freely arrange the blocks before completing the task. Despite performing better in the ordered condition, children with low working memory ability did not rate the ordered arrangement as easier, nor did they choose an ordered arrangement when given the opportunity to do so. This research shows that cognitive offloading can also be a useful process in populations other than typical adults, and the implications of this work for supporting children with poor working memory are discussed.
