The Einstellung effect occurs when the first idea that comes to mind, triggered by familiar features of a problem, prevents a better solution being found. It has been shown to affect both people facing novel problems and experts within their field of expertise. We show that it works by influencing mechanisms that determine what information is attended to. Having found one solution, expert chess players reported that they were looking for a better one. But their eye movements showed that they (...) continued to look at features of the problem related to the solution they had already thought of. The mechanism which allows the first schema activated by familiar aspects of a problem to control the subsequent direction of attention may contribute to a wide range of biases both in everyday and expert thought - from confirmation bias in hypothesis testing to the tendency of scientists to ignore results that do not fit their favoured theories.

Computational models of learning provide an alternative technique for identifying the number and type of chunks used by a subject in a specific task. Results from applying CHREST to chess expertise support the theoretical framework of Cowan and a limit in visual short-term memory capacity of 3–4 looms. An application to learning from diagrams illustrates different identifiable forms of chunk.

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level, players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong enough to override general expertise—players remembering positions and solving problems from their area of specialization performed at around the level of players 1 standard deviation (SD) above them in general skill. (...) Their problem‐solving strategy also changed depending on whether the problem was within their area of specialization. When it was, they searched more in depth and less in breadth; with problems outside their area of specialization, the reverse. The knowledge that comes from familiarity with a problem area is more important than general purpose strategies in determining how an expert will tackle it. These results demonstrate the link in experts between problem solving and memory of specific experiences and indicate that the search for context‐independent general purpose problem‐solving strategies to teach to future experts is unlikely to be successful.

In this study we use a computational model of language learning called model of syntax acquisition in children (MOSAIC) to investigate the extent to which the optional infinitive (OI) phenomenon in Dutch and English can be explained in terms of a resource-limited distributional analysis of Dutch and English child-directed speech. The results show that the same version of MOSAIC is able to simulate changes in the pattern of finiteness marking in 2 children learning Dutch and 2 children learning English as (...) the average length of their utterances increases. These results suggest that it is possible to explain the key features of the OI phenomenon in both Dutch and English in terms of the interaction between an utterance-final bias in learning and the distributional characteristics of child-directed speech in the 2 languages. They also show how computational modeling techniques can be used to investigate the extent to which cross-linguistic similarities in the developmental data can be explained in terms of common processing constraints as opposed to innate knowledge of universal grammar.

In this commentary, we discuss an important pattern of results in the literature on the neural basis of expertise: decrease of cerebral activation at the beginning of acquisition of expertise and functional cerebral reorganization as a consequence of years of practice. We show how these two results can be integrated with the neural reuse framework.

The original book chapter does not have an abstract. However, I have written an abstract for this repository: Religious life encompasses a wide diversity of situations for which the emotional tone is on a continuum from extreme euphoria to extreme dysphoria. In this book chapter, we propose the novel hypothesis that euphoria and dysphoria have distinctly separate functional consequences for religious evolution and survivability. This is due to the differential cognitive states that are created in euphoric and dysphoric situations. Based (...) on readings from religious studies and cognitive psychology, we propose that euphoria in religion is conducive to social bonding and situations needing lateral thinking and creativity; whereas dysphoria in religion is conducive to situations where precision and analogical reasoning are necessary.

This paper develops the very basic notions of analysis in a weak second-order theory of arithmetic BTFA whose provably total functions are the polynomial time computable functions. We formalize within BTFA the real number system and the notion of a continuous real function of a real variable. The theory BTFA is able to prove the intermediate value theorem, wherefore it follows that the system of real numbers is a real closed ordered field. In the last section of the paper, we (...) show how to interpret the theory BTFA in Robinson's theory of arithmetic Q. This fact entails that the elementary theory of the real closed ordered fields is interpretable in Q. (shrink)

Cet ouvrage se veut une lecture rhétorique de quelques problèmes-clés ayant marqué la période qui s'étend des débuts de la révolution scientifique du XVIIe siècle jusqu'au moment où, au XIXe, une autre se prépare. Une telle sorte d'analyse se fonde sur le fait qu'avant d'intervenir dans les efforts de persuasion, certains schèmes " poétiques " sont déjà présents et actifs dans la formation et l'acceptation de toute représentation nouvelle. C'est pourquoi la " rhétorique profonde " que nous propose ici (...) class='Hi'>Fernand Hallyn ne se contente nullement d'éclairer les procédés de la science qui interviennent dans la communication de positions, de démarches ou de résultats, mais vise d'abord à étudier ses formes d'invention et de découverte. Saisir la démarche scientifique en train de se faire comme un cas particulier de la problématique générale de la créativité - bref explorer plus avant la voie ouverte dans La Structure poétique du mande - tel est donc l'enjeu de ce volume.

Analyse : Esquisse des théories politiques de Constant.

Benzodiazepines and antidepressants have been shown to change responses to unfairness; however, the effects of their combined use on unfairness evaluation are unknown. This study examines the effects of concomitant benzodiazepines and antidepressants long-term use on the evaluation of fair and unfair offers. To analyze behavioral changes on responses to unfairness, we compared the performance of medicated participants and healthy controls in the Ultimatum Game, both in the proposer and in the respondent role. The results showed that long-term psychotropic users (...) had the worse economic strategy by accepting less offers than control subjects. However, in the proposer role, the unfair offers made by participants were similar between groups. The present results suggest that long-term use of psychotropic medication, specifically the combination of benzodiazepines and antidepressants, may increase the sensitivity to unfairness, resulting in higher rejection rates in conditions where this strategy is the most disadvantageous.

Este artigo se propõe a pensar a fenomenologia dos fenômenos: intuição categorial, evidência,verdade e ser, através da interpretação de textos de Husserl e Heidegger. Num primeiromomento mostra a intuição em sua maior pregnância, a percepção, como experiência daevidência da presença do ente mesmo como autodatidade originária. Num segundo momento,partindo da regionalidade e da universalidade da evidência na vida intencional da consciência,trata-se da razão, de seu ordenamento para a evidência e de sua correlação com a verdade e oser. Num terceiro momento (...) se realiza uma interpretação fenomenológica da doutrinatradicional da verdade como adequação e se intenta mostrar que esta concepção de verdade éderivada e se deixa reconduzir à verdade como manifestação do ser do ente. Num quartomomento discorre-se a respeito de dois significados de ser: ser no significado de serverdadeiroe ser na função da cópula. Por último, tenta-se acenar para a evidência do ser epara o relacionamento humano em face dela. (shrink)

Electron microscopic examination of the non‐granulated cells of the adenohypophysis of several species has evidenced a unity of structure amongst vertebrates. Efforts to correlate structure and function have been made, but they have often been hampered by the scarcity or absence of direct experimental methods for the investigation of their function. Yet often the evidence in favor of a given role has been circumstantial, relying on coincidences between changes in the secretory activity of the gland and changes in the ultrastructure (...) of the non‐granulated cells or in colloid production. At the present time, the prevailing hypothesis is that, in addition to a possible role in mechanical support within the gland, the non‐granulated cells seem to be important with respect to the secretory process of the endocrine cells and/or to the metabolism of the adenohypophysis.

Reichenbach explains temporally asymmetric phenomena by appeal to entropy and ‘branch structure’. He explains why the entropic gradients of isolated subsystems are oriented towards the future and not the past, and why we have records of the past and not the future, by appeal to the fact that the universe is currently on a long entropic upgrade with subsystems that branch off and become quasi-isolated. Reichenbach’s approach has been criticised for relying too closely on entropy. The more popular approach nowadays (...) is to appeal instead to a particular low-entropy initial state—Albert’s ‘Past Hypothesis’. I’ll argue that this neglect of Reichenbach’s approach is unwarranted. A Reichenbachian account has important advantages over Albert’s: it correctly identifies the minimal temporally asymmetric posit needed to derive key temporally asymmetries and it offers a more adequate account of the record asymmetry. While a Reichenbachian account needs to be supplemented, it provides the right foundations for explaining temporally asymmetric phenomena and what we might ultimately mean by ‘the direction of time’.

Com este artigo pretende-se argumentar pela possibilidade de uma escrita historiográfica em instância memorial, fazendo valer argumentos já esgrimidos por Ortega y Gasset, agora revistos criticamente desde uma base pragmatista. Pretende-se igualmente dar uma primeira resposta ao problema da relação de prioridade entre a história e a vida, mostrando que a vida tem desde logo um sentido historial.

El presente artículo desea reflexionar, por un lado, sobre la necesidad de una formación integral de los agentes sanitarios, que contemple la dimensión espiritual; y, por otro lado, sobre la necesidad de una mejor preparación de los agentes religiosos que trabajan en hospitales y centros de salud, para que en sus intereses y preocupaciones por los enfermos, se eviten las dicotomías en nombre de la fe o en nombre de la razón. La promoción del diálogo entre razón y fe reduce (...) la distancia entre las ciencias y evita el divorcio entre la praxis de la fe y la praxis de la ciencia, revelando que, a pesar de ser distintas por sus grados de certeza, pueden estar próximas por el objeto: la búsqueda de la verdad que libera al ser humano de todas las formas de injusticia y opresión, generadoras de malestar y enfermedades sicosomáticas. This paper intends to reflect, on one hand, the need for an integral education of healthcare agents, that addresses the spiritual dimension; and, on the other hand, the need for a better preparation of religious agents that work in hopitals and health centers, so that, in the interest and concern for sick people, dichotomies in the name of faith or in the name of reason are prevented. The promotion of dialogue between reason and faith shortens the distance between sciences and avoids a divorce between praxis of faith and praxis of science, showing that, despite the different degrees of certainty, may be close by the object: the search for the truth that liberates human beings of all forms of injustice and oppression, disease generators and psychosomatic illnesses.

In den Philosophischen Brocken kritisiert Kierkegaard die sokratische Präexistenzlehre wegen ihrer nihilistischen Konsequenzen für die Zeitlichkeit: Das geschichtliche Dasein des Menschen wäre überflüssig, wenn er a priori bereits vollendet wäre. Weil Kierkegaard in seiner christlichen Argumentation dennoch nicht umhin kann, selbst ein Analogon zum vorgeburtlichen Sein der Seele bei Platon vorauszusetzen, wendet er in der religiösen Schrift Die Krankheit zum Tode einen sophistischen Trick an, mit dessen Hilfe er die Präexistenzimplikation aus dem Bewusstsein des Lesers verdrängen will.

Si le tragique n'est pas le propre de la tragédie grecque mais bien celui de 'l'être au monde de l'homme', sa conceptualisation n'advient qu'avec Wilderlin lorsque celui-ci s'approprie la question 'Comment lit-on la tragédie?', non plus selon son acception poétique, mais en tant que forme philosophique. Et si l'on suit sa réflexion, à la question 'Qu'est-ce que le tragique?', on notera qu'il est une façon d'être au monde de manière spéculative. L'union des contraires, de la poésie et de la sagesse, (...) voilà ce qui a tant plu à Empédocle, Hölderlin et Nietzsche. Si Je est un autre, la pensée tragique représente l'individu conscient de lui-même dans sa totalité. Mais, un personnage tragique n'est-il pas destiné à exister dans l'Histoire? Pour ces trois poètes, il s'agissait de traduire le monde du symbole, de la parabole, ou de l'allégorie en une nouvelle langue. En relisant de cette manière le tragique du monde, se découvre un sens qu'Empédocle, Hölderlin ou Nietzsche illuminèrent de leur regard: la mort dans les esquisses d'une tragédie pour Hölderlin et Nietzsche, ou la chute du démon chez Empédocle, traduisent la relation des oppositions dans l'absolu de la disparition"--Page 4 of cover.

O presente trabalho visa discutir a política exterior brasileira no imediato pós-Segunda Guerra Mundial sob a ótica do conceito de imposição do alinhamento. O fim do conflito trouxe consigo uma nova configuração das relações internacionais. O posicionamento brasileiro durante o período foi alvo de diversas análises que buscavam compreender a maneira como o presidente Eurico Gaspar Dutra conduziu a política externa do país. O momento de disputa por áreas de influência entre Estados Unidos da América e União Soviética poderia lograr (...) vantagens ao Brasil. Entretanto, a postura do governo brasileiro não permitiu que o país alcançasse seus objetivos do ponto de vista da política internacional já que seu alinhamento aos norte-americanos foi automático, diferentemente do que defende a imposição do alinhamento. O conceito sustenta que o atendimento das expectativas do governo dos EUA não era simplesmente sinônimo de subserviência aos interesses estadunidenses, mas uma condição a que o Brasil estava sujeito.

In einer philosophischen Inhaltsangabe und Interpretation versuche ich, die Doppeldeutigkeit der Vergeltungsmetapher im Ijob-Buch herauszuarbeiten. Entgegen den geläufigen theologischen oder pessimistischen Deutungsvarianten ist dabei streng zwischen einer vorreflexiv-moralischen und metaphysischen Sinnebene zu unterscheiden. Während Ijobs Freunde über das Referat einer noch nicht vernünftig angeeigneten Tradition nicht hinauskommen, entwickelt sich der ,,Angefeindete" zweifelnd und philosophisch suchend zu einem geistigen Individuum, indem er die Einschränkungen eines endlichen Daseins letztlich als ermöglichende Bedingungen seiner Freiheit erkennt, sich aus dem Seinsgrund der Gerechtigkeit Gottes selbst (...) zu gestalten.
