Muscle Damaging Exercise Affects Isometric Force Fluctuation as well as Intraindividual Variability of Cognitive Function

Healthy untrained men (N = 11) were asked to perform 10 series of 12 repetitions of knee eccentric extension (EE) at 160° per second. Quadriceps muscle torques evoked by electrical stimulation at 20 Hz (P20) and 100 Hz (P100), maximal voluntary isometric contraction torque (MVC), maximal isokinetic concentric torque (IT) at 30° per second, voluntary activation index (VA), simple reaction time (RTs), complex reaction time (RTc), and torque variability at 30% of MVC were measured before EE, immediately after EE, and 60 min and 24 hr after EE. MVC, IT, P20, P100, and VA decreased significantly after EE and remained depressed 24 hr later. Torque variability increased significantly after EE. Average RTs and RTc did not change after EE, whereas intraindividual variability in RTs and RTc increased significantly after EE.     

Consequentializing and Underdetermination

The paper explores a new interpretation of the consequentializing project. Three prominent interpretations are criticized for neglecting the explanatory dimension of moral theories. Instead, it is argued that consequentializing leads to a phenomenon that is structurally analogous to one in science—the underdetermination of theory by evidence. This provides important insights into the consequentializing debate, and advances our general understanding of the moral domain.     

Object detection in natural scenes: Independent effects of spatial and category-based attention

Humans are remarkably efficient in detecting highly familiar object categories in natural scenes, with evidence suggesting that such object detection can be performed in the (near) absence of attention. Here we systematically explored the influences of both spatial attention and category-based attention on the accuracy of object detection in natural scenes. Manipulating both types of attention additionally allowed for addressing how these factors interact: whether the requirement for spatial attention depends on the extent to which observers are prepared to detect a specific object category—that is, on category-based attention. The results showed that the detection of targets from one category (animals or vehicles) was better than the detection of targets from two categories (animals and vehicles), demonstrating the beneficial effect of category-based attention. This effect did not depend on the semantic congruency of the target object and the background scene, indicating that observers attended to visual features diagnostic of the foreground target objects from the cued category. Importantly, in three experiments the detection of objects in scenes presented in the periphery was significantly impaired when observers simultaneously performed an attentionally demanding task at fixation, showing that spatial attention affects natural scene perception. In all experiments, the effects of category-based attention and spatial attention on object detection performance were additive rather than interactive. Finally, neither spatial nor category-based attention influenced metacognitive ability for object detection performance. These findings demonstrate that efficient object detection in natural scenes is independently facilitated by spatial and category-based attention.     

Lyotard’s performance

Starting with Lyotard’s characterisation of postmodernity as incredulity, this is related to another of his key concepts—that of ‘performativity’. Lyotard appears to deploy performativity to characterise those technologies that bring about the optimisation of efficient performance. However, there is another sense of performativity where it is linked to performance. Performance conditions the possibility of any and all performatives, or to put it another way, as performance is itself enabled by performativity, so too performativity is realised through its performance. Both senses of performativity and the linkage between them are clearly manifested in the space of knowledge production that is the contemporary university. This linkage is itself a feature of the semiotic process within which contemporary knowledge and knowledge production is located and which Lyotard himself recognised, albeit implicitly. The implication of this therefore is that Lyotard himself performs his text and in so doing both manifests and contributes to realising both senses of performativity.     

The rich are different: Unravelling the perceived and self‐reported personality profiles of high‐net‐worth individuals

Beyond money and possessions, how are the rich different from the general population? Drawing on a unique sample of high‐net‐worth individuals from Germany (≥1 million Euro in financial assets; N = 130), nationally representative data (N = 22,981), and an additional online panel (N = 690), we provide the first direct investigation of the stereotypically perceived and self‐reported personality profiles of high‐net‐worth individuals. Investigating the broad personality traits of the Big Five and the more specific traits of narcissism and locus of control, we find that stereotypes about wealthy people's personality are accurate albeit somewhat exaggerated and that wealthy people can be characterized as stable, flexible, and agentic individuals who are focused more on themselves than on others.     

Religious Schools and Discipline

Recently there has been a growing interest in faith-based schools (see e.g. The Times , No. 67060, 2 December 2001, pp. 1, 4). Politicians have indicated a willingness to support such schools on the assumption that religion may make a positive contribution to schooling. It is not at all self-evident that there is a clear inter-relationship between religion and education on which the assumption can be grounded. In what follows I shall seek to explore one sphere in which religion can have a bearing on schooling, notably on its understanding and practice of discipline. Before the specifically religious impact can be explored, the complex nature of discipline and reward/punishment in school is examined. The philosophy of behaviourism is rejected as inadequate for the processes of education, not least because of the insights of Nietzsche and Plato. The analysis leads to the identification of three very distinct forms of discipline, namely, authoritarian, moral and 'Socratic'. Whilst in practice schools may resort to all three, they would not necessarily do so in a coherent way as the authoritarian and moral forms of discipline are, in important respects, incompatible. The understanding of what religion is, is also shown to be of a varied nature. Differing views and features of religion can serve to reinforce the school as an authoritarian, moral or 'Socratic' community. Whilst the inherent authoritarianism of religion and the ethical dimension of religion are well known, a 'Kierkegaardian' view of religion would have strong affinities with 'Socratic' discipline and help to support the view of the school as a community for all.     

Temperance: with a consideration of evil,violence, and pedagogy

The article investigates the meaning of temperance by noting some cultural assumptions, raising the question as to why this classical virtue has largely disappeared from modern ethical discourse. By means of some historical notes temperance is identified as the unifying virtue in the person and in society. In its Christian form it is related to love of the transcendent goal of human life. By being similarly goal driven, education should consider the cardinal virtues and celebrate them through worship.     

Agency,Teleological Control and Robust Causation

I propose a compatibilist theory of agency and responsibility, according to which an agent is responsible for an effect, if and only if, she is the earliest source of robust causation over it, via an action she carried out in the service of her long term interests. This theory deploys a notion of teleological control, which is a type of guidance-control of the agent over the effect and it involves action plans and means-end reasoning. The theory makes room for degrees of responsibility, and accounts for the distinction between compulsion and determination. The teleological control view is informed by neuroscience and cognitive theory, and while it is indifferent to the distinction between determinism and indeterminism, it contends that the property of natural laws relevant to agency is the presence of successive stages of attractor and bifurcation dynamics. While the former grounds robust causation over effects of actions, the latter limits the temporal range of robustness, allowing us to characterize responsibility in terms of the earliest sources of robust causation.     

Don't trust anybody: Conspiracy mentality and the detection of facial trustworthiness cues

Conspiracy theories express mistrust in common explanations and epistemic authorities. Independent of concrete content, the extent of endorsing conspiracy theories has also shown associations with interpersonal mistrust. Arguing from an evolutionary and error-management perspective, this increased interpersonal mistrust could either represent an enhanced sensitivity to untrustworthiness cues, or a limited ability to recognize trustworthiness, or non-specific mistrust without differentiations between (un)trustworthiness cues. In two experimental studies (N = 563), we manipulated facial trustworthiness and tested the differentiation of trustworthiness evaluations as a function of conspiracy mentality. We found that conspiracy mentality was associated with a generalized tendency to perceive others as untrustworthy, independent of facial trustworthiness, speaking to non-specific manifestations of mistrust. However, the association between conspiracy mentality and trust became non-significant once age was accounted for in Study 1. We discuss how conspiracy mentality may be associated with an increased propensity to view the world as having malevolent intentions.     

When does procedural fairness promote organizational citizenship behavior? Integrating empowering leadership types in relational justice models

We examined how procedural fairness interacts with empowering leadership to promote employee OCB. We focused on two core empowering leadership types—encouraging self-development and encouraging independent action. An experiment revealed that leaders encouraging self-development made employees desire status information more (i.e., information regarding one’s value to the organization). Conversely, leaders encouraging independent action decreased employees’ desire for this type of information. Subsequently, a multisource field study (with a US and German sample) showed that encouraging self-development strengthened the relationship between procedural fairness and employee OCB, and this relationship was mediated by employees’ self-perceived status. Conversely, encouraging independent action weakened the procedural fairness-OCB relationship, as mediated by self-perceived status. This research integrates empowering leadership styles into relational fairness theories, highlighting that multiple leader behaviors should be examined in concert and that empowering leadership can have unintended consequences.
