Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

Recently a role for the vagus nerve in conditioning food preferences was established in rodents. In a prospective controlled clinical trial in humans, invasive vagus nerve stimulation shifted food choice toward lower fat content. Here we explored whether hedonic aspects of an orally sampled food stimulus can be modulated by non-invasive transcutaneous vagus nerve stimulation (tVNS) in humans. In healthy participants (n= 10, five women, 20–32 years old, no obesity) we tested liking and wanting ratings of food samples with varying (...) fat or sugar content with or without tVNS in a sham-controlled within-participants design. To determine effects of tVNS on food intake, we also measured voluntary consumption of milkshake. Spontaneous eye blink rate was measured as a proxy for dopamine tone. Liking of low-fat, but not high-fat puddings, was higher for tVNS relative to sham stimulation. Other outcomes showed no differences. These findings support a role for the vagus nerve promoting post-ingestive reward signals. Our results suggest that tVNS may be used to increase liking of low-calorie foods, which may support healthier food choices. (shrink)

En estas páginas hemos presentado varios argumentos para defender que existe una conexión entre el empleo de heurísticas y los procesos de deliberación. En lugar de caracterizar las heurísticas en función de las disciplinas, los campos y/o los ámbitos en que se emplean—tal y como hace, por ejemplo, el grupo ABC, i.e. racionalidad ecológica—las hemos proyectado sobre nuestros enclaves deliberativos, esto es, sobre un espacio eminentemente retórico y político. En dichos enclaves, tal y como solía recordarnos Quintín Racionero, la téchne (...) de la persuasión se nos presenta como parte del órganon de la filosofía práctica porque está aplicada a un espacio ontológico fundado por la comunicación humana. Y es en el seno de dicha comunicación como cabe entender la proliferación de razonamientos heurísticos encaminados al cálculo, la estimación y/o la ponderación, con ayuda de los cuales no sólo se orienta la acción colectiva sino las mismas fases de la deliberación.

La oposición a una estricta separación entre las dimensiones dialéctica y retórica de la actividad argumentativa es una de las aportaciones más destacadas y peculiares de la denominada escuela holandesa sobre argumentación. Frans H. van Eemeren y Peter Houtlosser reaccionaron contra una separación estricta entre dialéctica y retórica en varios trabajos, pero uno de los más inspiradores es sin duda su artículo “William the Silent’s argumentative discourse” (1998) presentado en la ciudad de Ámsterdam con ocasión de la cuarta conferencia organizada (...) por la International Society for the Study of Argumentation (ISSA). Sobre este tema siguieron investigando para presentar un análisis de la perspectiva dialéctica inherente al caso de Guillermo I de Orange en un congreso de la Japan Debate Association en Tokio (van Eemeren y Houtlosser, 2000).

Even when they are defined with precision, one can often read and hear judgments about the vagueness of heuristics in debates about heuristic reasoning. This opinion is not just frequent but also quite reasonable. In fact, during the 1990s, there was a certain controversy concerning this topic that confronted two of the leading groups in the field of heuristic reasoning research, each of whom held very different perspectives. In the present text, we will focus on two of the papers published (...) in Psychological Review, wherein the arguments of each of these groups were presented:. (shrink)

El estudio y análisis de las argumentaciones cotidianas entendidas como interacciones discursivas e intencionales encaminadas a dar cuenta de algo con el fin de lograr que aquello que se sostiene sea aceptado, sería inconcebible sin la aparición de la teoría de los actos de habla de Austin (1962), la propuesta de Searle (1969), el trabajo de Grice sobre la teoría de la conversación (1975) y el importante estudio sistemático de Hamblin sobre el argumento falaz (1970). Como una reelaboración de dichas (...) obras cabe entender la teoría pragmadialéctica de la argumentación propuesta inicialmente por Frans H. van Eemeren y Rob Grootendorst (1984). Algunos autores (Blair, 2006: 11; Woods, 1992) creen ver en ella, más que una teoría, una amalgama de varias teorías y una particular versión de la teoría pragmadialéctica de la argumentación, entendiendo ésta bajo una acepción más general. Otros consideran que ni es útil ni tampoco especulativamente productivo sostener que de toda argumentación pueda buscarse un modelo según el cual ésta buscaría resolver una diferencia de opinión (Goodwin, 1999).

This article explores the extent to which our deliberative culture determines our capacity to recognize relevant knowledge, to select and value epistemic authority, or to recognize the importance of individual and/or collective epistemic achievements in a deliberative context. This investigation is especially relevant in a moment in which the formation of public opinion no longer depends exclusively on political parties. This leads to a paradoxical situation in which the diffuse energy issued by the electorate is not easily subjected to the (...) discipline of party-oriented proposals or by media disputes that, despite their projection, may be ignored by many people. Thus, it is unclear in which sense social networks act as an alternative to the traditional system of intermediation set up by trade unions and pressure groups. By combining the approaches of deliberative democracy and social cognition theories, this essay sustains the relevance of what is defined here as ‘cooperative cognition’ in order to face this challenge.

Take the strong rhetoric! This expression comes to mind as we set in order the ideas and impressions prompted by Sandra Harding’s “An Organic Logic of Research: A Response to Posey and Navarro”.

Concepts as reasonable doubt, cognitive biases and emotions are now a theoretical problem for the practice of law, and the law understood as legal argumentation. From a theoretical point of view, the screenplay written by Reginald Rose, Twelve Angry Men, is an outstanding example to analyze some of these concepts, and its influence on procedural stage. Cognitive biases and informal fallacies are theoretical challenge to legal argumentation.

Der Begriff der Toleranz in der Moderne wurde erdacht mit dem Ziel, Gesellschaften zu organisieren, die sich im Umbruch befanden auf Grund des plötzlichen Eindringens von Glaubensunterschieden in die politische Raumordnung. Die Definition der Toleranz als Tugend, die auf der Nachgiebigkeit gegenüber dem Andersartigen basiert, ist ein Pseudobegriff. Die hermeneutische Veranlagung, die mit der Philosophie einhergeht, zeigt, dass die Toleranz keine schlichte moralische Tugend sein kann, sondern vielmehr eine der Beschaffenheiten der Möglichkeit rationaler Handlungen (die Arten des Seins und des (...) Sagens fallen in der Vielfältigkeit ihrer Formen zusammen). Die Geschichte der Hermeneutik zeigt seit ihren Anfängen – die exegetische Arbeit war hierbei grundlegend – die Zwickmühlen der Existenzformen der Rationalität und lässt nur ein Denken an der Grenze zu, welche ihre Grundlage ist: Es gibt keine Tatsachen, sondern Interpretationen.

One of the challenges related to the discursive practices of argumentative agents is to get to know if those interactions have an institutional effect. In this article, it is argued that in the new institutionalism, theoretical approaches and deterministic analysis are outlined to investigate argumentative practices that take place in processes of legitimation and recognition. Here a double socio-institutional and discursive or constructivist approach to the argumentation theory is defended, and it is argued that this perspective could be extended to (...) a research program aimed at interpreting argumentative processes in the public sphere that act as calculation mechanism and conformation of social capital.

Este artículo muestra la conexión entre heurísticas sociales y deliberación. En lugar de caracterizar las heurísticas según disciplinas o campos, aquí se proyectan sobre nuestros enclaves deliberativos. La autora sostiene que el empleo de heurísticas sociales orienta el flujo de la información y la participación en las distintas fases deliberativas, y es necesario analizarlas para establecer indicadores con los que medir grados de deliberación. Esta hipótesis da lugar a una visión pluralista sobre la función social de las heurísticas entendidas como (...) caja de herramientas con nuevos instrumentos y utilidades sociales. Según dicha perspectiva, habría que integrar este tipo de razonamiento en un plan de acción más amplio que explicara en qué sentido las heurísticas son recursos que producen conocimiento, al tiempo que un tipo de conocimiento ya producido.

«Fortaleza» y «debilidad» son dos adjetivos que se han utilizado prolijamente en la literatura científica sobre institucionalismo para describir la permanencia o, por el contrario, la porosidad y maleabilidad de las reglas y principios rectores en los que están atrincheradas las instituciones que sobreviven en equilibrio y, por tanto, no son alteradas unilateralmente.

Uno de los conceptos fundamentales del área de las Ciencias humanas y sociales es el de «cognición social». Este término se suele utilizar para referir teorías, categorías y principios que explican e interpretan fenómenos relacionados con el conocimiento que los seres humanos poseen sobre el mundo social.

Las definiciones de argumentación son tan variadas como las distintas posiciones existentes en torno a la pregunta de qué hacemos exactamente cuando argumentamos y cuándo estamos, de hecho, argumentando. Incluso el mismo autor puede ofrecer más de una definición de lo que entiende por argumentación; en parte, porque el problema de la argumentación no se circunscribe a un solo ámbito, ni del conocimiento ni de la vida práctica.

En este artículo se analiza el planteamiento de Reinhart Koselleck en torno a la Begriffsgeschichte desde el punto de vista de la productividad de la historia, el tiempo y la productividad propia de la dialéctica de los conceptos. Para ello se traen a colación aspectos muy precisos de la filosofía de Aristóteles, Hegel y Gadamer. La reflexión concluye extrayendo algunas aportaciones que podrían enriquecer la investigación de Koselleck.

The relationship between the necessity to ensure that information is shared in the stages of deliberation and the overcoming of what Dryzek (2001) called constriction of deliberative economy is directly related to the proponents and opponents’ propensity to submit and add information differently, in a plural manner. This article describes the salient features of the deliberative turn in order to defend that this propensity is not individual. The evolution of the public space in science and in politics are both paradigmatic (...) examples to appreciate that individual deliberation, and even mere aggregation of opinions, are consistently interpreted only if they are part of social practices and collective institutions aimed at defending tolerance towards positions, beliefs and interpretations that are different or even confronted. This paper argues that the so called model of contestatory deliberative democracy contributes to the acquisition of knowledge precisely because it fosters a plurality of epistemic states associated with practices as consensus and dissent.

Lorenzo Peña y Gonzalo has developed a logic, a legal philosophy and a political thought of a deeply neo-Leibnizian nature. The neo-Leibnizian mark characterizes both his philosophical thesis and the terms has coined in his contributions to the theory of knowledge, theodicy, ontology, political philosophy, etc. Above all, this mark is present in his conception of Law and of the logic of legal situations. Under the light of the political problems and crossroads of the present time, this interview allows for (...) an approach to some of the intellectual findings in his work. (shrink)

In this article, the hypothesis according to which the institutional change is determined by the mobilization of social capital is exposed. It is analysed what consequences derived from this fact in relation to the processes of deinstitutionalization of the policy. It proposes an interpretation of academically relevant results about the meaning of the term ‘deinstitutionalization’, explains some of the most important antecedents on institutional theory and, fially, proposes some fundamental ideas to advance the philosophical reflction about the so-called new institutionalism.

When are we, in fact, arguing? Even one and the same author may offer more than one definition of what he understands by argumentation: this is partly because the problem of argumentation is not confined to a single area of knowledge or of practical life. Definitions of argumentation are as varied as the different positions taken on the question of what exactly we do when we argue. Be that as it may, we are struck by the fact that the problem (...) of argumentation (above all in its application to hypothetic-inductive methods) has not been analysed as a problem linked to interpretation.

The objective of this paper is to analyse, from a philosophical perspective, the 16th and 17th Century models of currency, as well as their influence on the types of society in which the models developed. For this, the author values the study by the French philosopher Michael Foucault Words and Things on this matter and the principal foundations of Ludwig von Bertalanffy´s systems theory. The 17th Century model of currency is based on the notion of a system of exchange. The (...) notion of a system of exchange represents a transformation of great significance, upon which the principal characteristics of our current globalised era are founded, not only in economic life, but also in relation to an understanding of the world that it implies. Furthermore, the notion of a system of exchange was the step before the current model of electronic payments of the digital era, in which large transactions (and also large data transfers) take place by pressing a button. The principal idea of the paper is that these economic practices hold the key to deepen a philosophical and historical comprehension of concepts such as globalisation. (shrink)

In this paper art history and visual studies, the disciplines that study visual culture, are presented as a field whose conjectural paradigm can be used to understand the epistemic problems associated with abduction. In order to do so, significant statements, concepts and arguments from the work of several specialists in this field have been highlighted. Their analysis shows the fruitfulness and potential for understanding the study of visual culture as a field that is interwoven with the assumptions of abductive cognition.

If the cultural variations concerning knowledge and research on ordinary reasoning are part of cultural history, what kind of historiographical method is needed in order to present the history of its evolution? This paper proposes to introduce the study of theories of reasoning into a historiographic perspective because we assume that the answer to the previous question does not only depend of internal controversies about how reasoning performance is explained by current theories of reasoning.

"Aranguren: filosofía en la vida y vida en la filosofía" llevó por nombre la exposición sobre la figura y el legado de José Luis L. Aranguren (Ávila 1909- Madrid 1996) que pudo verse desde el 4 de junio al 26 de julio de 2009 en el Pabellón Transatlántico de la Residencia de Estudiantes de Madrid con ocasión del centenario del nacimiento del filósofo abulense.

Benito Pérez Galdós encontró en la clase media una fuente de inspiración para la creación de una novela de costumbres con una destacada dimensión política: describir y hacer comprensibles los problemas de índole moral que hacían muy difícil concebir e implantar un orden social basado en la prosperidad individual y colectiva. Aunque su talante descriptivo, su técnica realista, costumbrista e incluso naturalista, como se ha dicho en alguna ocasión —sin que estemos aquí completamente de acuerdo con ello—,es una de las (...) más sobresalientes de las letras españolas, Galdós nunca renunció al uso de una poderosa voz narrativa con la que imprimió a su literatura un declarado afán de comprensión de la realidad social.

The administrative discretionary act differs from regulated act because while the latter refers to the simple execution of the law, the former refers to cases where there is some leeway for a further understanding and application of the rule. For example, discretionary is necessary when the law can provide two possible proceedings, none of which is mandatory. It is also necessary when legislation merely indicates its ends, without specifying the means to achieve them. When it is not dissociated from the (...) exercise of the discretion of a constituted authority, discretionary is the opposite of arbitrariness. After defining this important notion, this paper emphasizes two highlights of it, namely, that the foundation of its power lies in the law itself, and that the distinguishing feature of a discretionary act is the justification of the reasons for the decision.

Si concebimos el bienestar como condición para que se dé auténtica dignidad en la vida individual y/o colectiva, entre diferentes especies y generaciones de especies, lo cierto es que cabría colegir que la dignidad no tiene una única naturaleza ni, en relación a la que cupiera definir como la más conveniente o necesaria o justa, se instituye conforme a idénticos grados. La (esencia de la) dignidad sería, por consiguiente, relativa. Analicemos esto.

In 1685, in The Art of Discovery, Leibniz set down an extraordinary idea: "The only way to rectify our reasonings is to make them as tangible as those of the Mathematicians, so that we can find our error at a glance, and when there are disputes among persons, we can simply say: Let us calculate [calculemus], without further ado, to see who is right." Calculemus.

A cognitive bias is a pattern of deviation in our judgment or our processing of what we perceive. Its raison d'être is the evolutionary need to produce immediate judgments in order to adopt a position quickly in response to stimuli, problems, or situations that catch our attention for some reason. They have a social dimension because they are present in the interactions and decision-making processes of ordinary life. They can be understood to be an adaptive response to human inability to (...) process all of the available information that we receive and selectively filter through biased reasoning or through procedures and heuristic rules.

Understanding Information and Communication Technologies through the networks in which people get con¬nected, communicate and co-operate has been a constant feature in the work of researchers who have not dissociated their view of the meaning of technologies from new social movements. This paper maintains that Information and Communication Technologies are not only networks that people join individually, but they also act as social technologies. Their improvement depends both on the diversity of their functions (social, political, cognitive, etc.) and the flexibility (...) with which they adapt to functional diversity (for example, to life cycles, changing and fluctuating mobility or audiovisual perception thresholds). This idea is supported by the new technological challenge represented by portable devices, such as, personal area networks, high-use user interfaces, and systems designed for home care. These important changes will be explored in this paper in connection with their value for education. (shrink)

Information and Communication Technologies are intended to develop, maintain and administrate information using computer systems, communication networks, portable dispositives, etc. In addition to that, this paper deals with ICT’s power to create new contexts: what is called digital ambiences. According to the author the design and even the concept of these intelligent ambiences has problems that have to do both with the use of reasoning and the display of inferential and interpretative processes to interact with the social context in an (...) individual or a collective way. Solving these philosophical problems could guide the development and implantation of ubiquitous and embodied technologies that would be able to amplify the cognitive and motive capacity of people.

La lógica borrosa se ha definido como un sistema preciso de razonamiento, deducción y computación en el que los objetos del discurso se encuentran asociados a información que, por lo general, consideramos imprecisa, incompleta, incierta, poco fiable, parcialmente verdadera o parcialmente posible.

Some authors sustain that historical research is an effect of a specific historiographical context (Jenkins, 1991; González de Oleaga, 2009). An approach to the historiographical debate between constructivism and recontructivism is presented in this paper. Two theses are here defended. The first one affirms that the above mentioned debate is deeply related to epistemological questions (study of mental representations, different conceptions about historical reasoning functions, historical reasoning, cognitive bias, and informal falacies). The second thesis affirms that each historiographical conception can (...) be understood as the effect of assuming a specific perspective about these epistemic questions. As an evidence of this, some connections between historiography and epistemology will be analysed through the analogy between the reconstructivism vs. constructivism debate, and the epistemological debate detectivism vs. constitutivism (Finkelstein, 2003).
