The Effect of Perceived Advantage and Disadvantage on Performance: The Role of External Efficacy

This experiment examined how perceptions of advantage and disadvantage determine performance in a competitive context. We distinguished between internal and external efficacy, and manipulated external efficacy by inducing perceptions of advantaged or disadvantaged starting positions in a competition, keeping the actual positions equal. The treatment increased the performance of the advantaged party and decreased the performance of the disadvantaged party. In addition, measured external and internal efficacy had qualitatively different effects on performance. The results are explained by the idea that losses loom larger than gains.     

The Coherence of Luck Egalitarianism

One of the foremost egalitarian theories in recent years, luck egalitarianism, has recently been subjected to the charge that it is in fact incoherent. This charge is brought by David Miller who highlights two dimensions of luck egalitarianism: on the one hand a commitment to the justice of certain inequalities arising from responsible choices; on the other a commitment to injustice of brute inequalities. The putative incoherence emerges in cases where the inequalities that justice requires on the basis of individuals' responsible choices also entail brute luck inequalities for which there are the very same grounds of justice to condemn. Here I argue that the charge of incoherence against luck egalitarianism fails. In service of this I clarify the quite specific sense in which luck egalitarianism requires inequalities and demonstrate the coherence of this with its condemnation of other inequalities.     

Ethical Issues In Linguistic Fieldwork: An Overview

Ethical issues in linguistic fieldwork have received surprisingly little direct attention in recent years. This article reviews ethical models for fieldwork and outlines the responsibilities of linguists involved in fieldwork on endangered languages to individuals, communities, and knowledge systems, focusing on fieldwork in a North American context.     

WAIMH position paper: Infants’ rights in wartime

The World Association for Infant Mental Health (WAIMH) decided to compose a position paper on infants’ rights in wartime, as there is still a general lack of attention paid to the impact of war-related traumas on infants’ development and psychological health. Though there are numerous areas of violent conflicts around the globe, there have been few published studies that relate specifically to infants. Consequently, humanitarian aid programs tend to overlook infants’ psychological needs and to pay more attention to those of older children. This position paper first reviews the studies identified through a literature search, about the impact of war-related traumas during pregnancy and postnatal periods, then describes the existing recommendations that have been added to the Children Rights Convention and their implications for infant mental health clinicians.     

PRAYING TOGETHER: CORPORATE PRAYER AND SHARED SITUATIONS

In this article, we give much needed attention to the nature and value of corporate prayer by drawing together insights from theology, philosophy, and psychology. First, we explain what it is that distinguishes corporate from private prayer by drawing on the psychological literature on joint attention and the philosophical notion of shared situations. We suggest that what is central to corporate prayer is a “sense of sharedness,” which can be established through a variety of means—through bodily interactions or through certain environments. Second, we argue that corporate prayer, when understood as a kind of shared situation, enables common knowledge, as well as a kind of alignment between participants. Through this process, participants’ attention is focused on the same target and affiliation between participants increases. Thus, we suggest, one benefit of understanding corporate prayer as a shared situation is that it establishes and deepens a sense of community in such a way that common purposes and goals can be enacted more effectively.     

Functional Thought Experiments

The literature on thought experiments has been mainly concernedwith thought experiments that are directed at a theory, be it in aconstructive or a destructive manner. This has led somephilosophers to argue that all thought experiments can beformulated as arguments. The aim of this paper is to drawattention to a type of thought experiment that is not directed ata theory, but fulfills a specific function within a theory. Suchthought experiments are referred to as functional thoughtexperiments, and they are routinely used in applied statistics. An example is given from frequentist statistics, where a thoughtexperiment is required to establish the probability space. It isconcluded that (a) not all thought experiments can be formulated asarguments, and (b) the role of thought experiments is more generaland more important to scientific reasoning than has previouslybeen recognized.     

Einstein and the most beautiful theories in physics

Einstein's theories of special and general relativity are unanimously praised by scientists for their extraordinary beauty to the extent that some consider the latter to be the most beautiful theory in physics. The grounds for these assertions are assessed here and it is concluded that the beauty of Einstein's theories can be attributed to two of their aspects. The first is that they incorporate all possible ingredients that constitute the beauty of theories: simplicity, symmetry, invariance, unification, etc. The second concerns the perfect logical consistency of Einstein's theories, a crucial factor in the unanimous praise of their beauty. Theories other than Einstein's are also assessed here, namely, electromagnetism and the various quantum theories, and it is concluded that all these suffer from logical flaws. This has resulted in a lack of consensus among scientists with respect to their beauty. Consequently, the unanimous claim that Einstein's theories are of superior beauty as compared to other theories in physics is hereby substantiated.     

Are average and symmetric faces attractive to infants? Discrimination and looking preferences

Young infants prefer to look at faces that adults find attractive, suggesting a biological basis for some face preferences. However, the basis for infant preferences is not known. Adults find average and symmetric faces attractive. We examined whether 5-8-month-old infants discriminate between different levels of averageness and symmetry in faces, and whether they prefer to look at faces with higher levels of these traits. Each infant saw 24 pairs of female faces. Each pair consisted of two versions of the same face differing either in averageness (12 pairs) or symmetry (12 pairs). Data from the mothers confirmed that adults preferred the more average and more symmetric versions in each pair. The infants were sensitive to differences in both averageness and symmetry, but showed no looking preference for the more average or more symmetric versions. On the contrary, longest looks were significantly longer for the less average versions, and both longest looks and first looks were marginally longer for the less symmetric versions. Mean looking times were also longer for the less average and less symmetric versions, but those differences were not significant. We suggest that the infant looking behaviour may reflect a novelty preference rather than an aesthetic preference.     

Word production deficits in schizophrenia

Fronto-cerebellar circuitry is implicated in word production. Data suggest that the cerebellum is involved in word search, whereas the prefrontal cortex underlies the selection of words from among competing alternatives. We explored the role of search and selection processes in word production deficits in schizophrenia patients. In Experiment 1, patients were impaired in a verb generation task under both high and low selection conditions but were more impaired in the high selection condition. In Experiment 2, when the difficulty level of search and selection conditions was equated in a word stem completion task, patients were only impaired in the search condition. Word search deficits underlie word production problems in schizophrenia, and may involve fronto-cerebellar dysfunction.
