Training with anxiety has a positive effect on expert perceptual–motor performance under pressure

In two experiments, we examined whether training with anxiety can prevent choking in experts performing perceptual–motor tasks. In Experiment 1, 17 expert basketball players practised free throws over a 5-week period with or without induced anxiety. Only after training with anxiety did performance no longer deteriorate during the anxiety posttest. In Experiment 2, 17 expert dart players practised dart throwing from a position high or low on a climbing wall, thus with or without anxiety. Again, only after training with anxiety was performance maintained during the anxiety posttest, despite higher levels of anxiety, heart rate, and perceived effort. It is concluded that practising under anxiety can prevent choking in expert perceptual–motor performance, as one acclimatizes to the specific processes accompanying anxiety.     

The rise of information in an evolutionary universe

This paper outlines the grand scenario of cosmic evolution by examining the ongoing changes among radiation, matter and life in standard, big‐bang cosmology. Using aspects of non‐equilibrium thermodynamics and information science, we argue that it is the contrasting temporal behavior of various energy densities that have given rise to the environments needed for the emergence of galaxies, stars, planets, and life forms. We furthermore argue that a necessary (though perhaps not sufficient) condition—a veritable prime mover—for the emergence of such ordered structures of growing complexity is the expansion of the Universe itself. Neither demon‐strably new science nor appeals to non‐science are needed to explain the impressive hierarchy of developmental change, from quark to quasar, from microbe to mind.

Happy Danes and Deep Incarnation

The new Copenhagen School of Deep Incarnation posits that, in Jesus Christ, God has become incarnate and therefore present “in, with, and under” all physical and biological processes. This claim raises the issue of “compatibilism,” according to which divine action and creaturely action are compatible, and “incompatibilism,” according to which divine action must be absent to allow for free creaturely action. Niels Henrik Gregersen, representing the Copenhagen School, affirms both compatibilism at the quantum level of physical activity and incompatibilism at the level of nature's self‐organization. This article points out the incoherence of this position along with the positions proffered by process theologians and kenotic theologians.     

Free Associations as a Measure of Stable Implicit Attitudes

Two studies explored the psychometric properties of free association methods for the assessment of attitudes. Even though the stability of the actual associations was rather low, psychometric properties of the valence estimates of the free associations were highly satisfactory. Valence estimates of associations were provided by independent judges who rated the valence of the associations that were generated by participants. Valence estimates of the associations showed satisfactory internal consistencies and retest reliabilities over three weeks. Additionally, valence estimates of the associations were significantly and independently related to both explicit self‐reported attitudes and implicit attitudes that were assessed with an Ossi–Wessi Implicit Association Test. Free association methods represent a useful complement to the family of implicit measures and are especially suitable for the assessment of non‐relative attitudes towards single attitude objects.

《齐物论》与竹林玄学

《庄子》作为“三玄”之一,在魏晋玄学中大行其道。阮籍和嵇康是两位在任自然的旗帜下发挥庄子思想的名士。分析发现,阮籍对庄子的理解,大致来自《齐物论》。然《齐物论》对他的意义是双重的：既排遣其对现实的不满,又给因对现实的无能为力而游戏人生的生活态度提供掩饰。嵇康学理上的表现在于,其“声无哀乐”的见解,以乐论的形式,对《齐物论》中齐是非的观点作独特的补充,同时,却又在讨论人格的公（诚）私（伪）之分时,把它同是非问题联系起来,从而显露自己无法掩饰的价值立场。阮、嵇无论是言还是行的矛盾,都与庄子齐是非的悖论有关。     

A critique of Vihvelin's Three-fold Classification

In this essay, I argue for the rejection of Vihvelin's ‘Three-fold Classification’ (3-FC), a nonstandard taxonomy of free-will compatibilism, incompatibilism, and impossibilism. Vihvelin is right that the standard taxonomy of these views is inadequate, and that a new taxonomy is needed to clarify the free-will debate. Significantly, Vihvelin notes that the standard formal definition of ‘incompatibilism’ does not capture the historically popular view that deterministic laws pose a threat to free will. Vihvelin's proposed solution is to redefine ‘incompatibilism.’ However, Vihvelin's formal definition of ‘incompatibilism’ is flawed according to her own arguments. In addition, Vihvelin's characterization of ‘compatibilism’ is (at best) incomplete, and at least two important free-will views are missing from her proposed taxonomy. Given the problems with Vihvelin's arguments for 3-FC, her novel view of the dialectic between the major free-will views lacks support.     

Segregation of copper in an Fe–Cu alloy under pulsed electric current

Effect of electric current on the segregation of copper precipitates in the Fe–13.6Cu alloy is evaluated. Results of this approach present two stages of segregation, namely, grain-boundary segregation during the solidification and interphase-boundary segregation during the decomposition of a solid solution. The segregation becomes apparent not only because the thermodynamic barrier for segregation is decreased, but also because the diffusion is greatly enhanced. Based on the thermodynamic and kinetic aspects, the segregation process under electric current would be of great interest and of physical importance because this kind of electric current-induced segregation was much stronger than the thermal diffusion segregation.     

A Wandering Mind is Not Always a Creative Mind: How Thought Dynamics Explain the Relationship between Mind Wandering and Creativity

A wandering mind is not always a creative mind. Anecdotes about ideas spontaneously entering awareness during walks, showers, and other off-task activities are plenty. The science behind it, however, is still inconclusive. Creativity might result from how thought context—whether thoughts are on-task or off-task—relates to thought dynamics—how thoughts unfold. To explore this, study 1 (n = 85) surveyed creative professionals about a single idea they had earlier in the day. The spontaneity of thoughts positively correlated with self-reported creativity, whereas off-task thoughts or doing something else did not. Study 2 (n = 180) replicated these findings in a student sample during an idea generation task and added that free movement of thoughts also correlates with self-reported originality during idea generation. As indicated by expert ratings, no relationship of thought dynamics and thought context was found with population-level creativity. Herewith, this study suggests that thought dynamics, rather than thought context, explain the often suggested relationship between mind wandering and creativity.     

Ensuring Liberties: Understanding State Restrictions on Religious Freedoms

Promises of religious freedoms have become the standard in national constitutions. Yet, despite these assurances, religious freedoms are routinely denied. Combining new data collections with expanded theoretical explanations, this research explores how dimensions of governance and measures of the religious economy contribute to government restrictions on religion. Consistent with recent work on the judicialization of politics, we find that the absence of an independent judiciary is an important predictor of government restrictions on religious freedoms, whereas free elections and government effectiveness are insignificant in our full models. Consistent with the religious economy theory, we find that social restrictions and government favoritism toward a religion(s) are persistent predictors of the government's restrictions. Although the proportion of the population Muslim holds a strong bivariate association with government restrictions (r = .57), the relationship is reduced to insignificance in our full models. We briefly discuss the implications of these findings.
