Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

Das Netz der Kultur bildet eine kommunikative Medialität, in der sich Freiheitsspielräume des menschlichen Lebens eröffnen.

Zu den bedeutendsten Leistungen der Friedensschrift Kants für die Entwicklung der Völkerrechtsidee gehört die Zurückweisung der bisherigen Leitvorstellung eines ius ad bellum. Unmißverständlich formuliert er: „Bei dem Begriffe des Völkerrechts, als eines Rechts zum Kriege, läßt sich eigentlich gar nichts denken“ . Eine internationale Rechtsordnung müsse dem Ziele dauerhafter Friedenssicherung dienen, und in einem Bund freier Völker soll dieser zwischenstaatliche Konsens institutionalisiert werden.

This paper explores structuralism as a way to model theories from scientific practice. As a case study I analyzed a theory about the dynamics of the basal ganglia, a part of the brain that is involved in Parkinson's disease. After introducing the case study I explore how to structurally represent qualitative assumptions about disease, intervention and dynamical systems in general. I further explicate the structure of the basal ganglia theory in detail, how it explains Parkinson's disease and how it implies (...) treatments. I close with a consideration of how a structuralist representation could be useful in practice to explore and develop theories with the aid of a computer. (shrink)

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

Fiodor Dostoievski rasga el alma humana hasta dejarla herida por el sufrimiento, la culpa y el aislamiento. Y, sin embargo, la derrota no gana la batalla. La escritora sureña estadounidense Carson McCullers escribe sobre la soledad y la miseria del sur de los Estados Unidos con una mirada atenta a los paisajes desolados de la Rusia de Fiodor Dostoievski, no sólo físicos sino esencialmente metafísicos. Esta autora que ya leyó al maestro ruso a los 13 años explora las entrañas humanas (...) desde un terreno rural, desolador, inhóspito y desafortunado, con diferencias raciales, sobreexposición de alcohol y con un concepto de bien moral interno que aparece como una pulsión constante e inagotable. En esta aproximación queremos destacar cómo el misterio del mal, pero también el acto de la voluntad y la incomunicación, son aspectos que unen a ambos autores, especialmente en dos de sus obras maestras, Crimen y Castigo y El corazón es un cazador solitario, respectivamente.

Substantial advances in our understanding of the neural bases of emotional processing have been made over the past decades. Overall, studies in humans and other animals highlight the key role of the amygdala in the detection and evaluation of stimuli with affective value. Nonetheless, contradictory findings have been reported, especially in terms of the exact role of this structure in the processing of different emotions, giving rise to different neural models of emotion. For instance, although the amygdala has traditionally been (...) considered as exclusively involved in fear (and possibly anger), more recent work suggests that it may be important for processing other types of emotions, and even nonemotional information. A review of the main findings in this field is presented here, together with some of the hypotheses that have been put forward to interpret this literature and explain its inconsistencies. (shrink)

Research on Augmented Reality in education has demonstrated that AR applications designed with diverse components boost student motivation in educational settings. However, most of the research conducted to date, does not define exactly what those components are and how these components positively affect student motivation. This study, therefore, attempts to identify some of the components that positively affect student motivation in mobile AR learning experiences to contribute to the design and development of motivational AR learning experiences for the Vocational Education (...) and Training level of education. To identify these components, a research model constructed from the literature was empirically validated with data obtained from two sources: 35 students from four VET institutes interacting with an AR application for learning for a period of 20 days, and a self-report measure obtained from the Instructional Materials Motivation Survey. We found that the following variables: use of scaffolding, real-time feedback, degree of success, time on-task and learning outcomes are positively correlated with the four dimensions of the ARCS model of motivation: Attention, Relevance, Confidence, and Satisfaction. Implications of these results are also described. (shrink)

Vera Zasulich’s shooting of Trepov, a governor of St Petersburg who had ordered the flogging of a political prisoner, in January 1878, catapulted her to international fame as a revolutionary heroine, a reputation that she put to good use by becoming one of the five ‘founding parents’ of Russian Marxism that created the ‘Group for the Emancipation of Labour’ in 1883. But her act of self-sacrifice also triggered, to her dismay, the institutionalisation of individual terrorist tactics in the Russian Populist (...) movement with the creation of the ‘People’s Will’ (Narodnaya Volya) Party in 1879. The organisation went into decline after the killing of Tsar Alexander II in 1881, and Populism itself was increasingly superseded by Marxism as the hegemonic force on the left with the rise of the Russian Social Democratic Labour Party (RSDLP). But individual terrorist tactics reappeared with the creation of the Socialist Revolutionary Party in 1902, prompting Zasulich to write an article for Die neue Zeit, the theoretical organ of German Social Democracy, in which she both condemned the Neo-Populist tendency as deleterious to the rising labour movement and supported the organisational plans for the RSDLP sponsored by the Iskra group, developed at length by Lenin in his book What Is to Be Done?, published in March 1902. This article provides the background to Vera Zasulich’s article ‘The Terrorist Tendency in Russia’ (December 1902), setting it against the history of the Russian revolutionary movement from 1878 to 1902.

Hannah Arendts politischer Theorie liegt eine relationale Ontologie zugrunde, in der Pluralität und singuläre Freiheit in einem wechselseitigen Bedingungsverhältnis stehen. Das politische Zusammenhandeln setzt freie Individuen voraus, die sich im Netzwerk sozialer Beziehungen differenzieren und identifizieren. Freiheit verwirklicht sich als Partizipation an öffentlicher Verständigung, in der die lebensweltliche Begrenztheit der eigenen Perspektive durch die Auseinandersetzung mit anderen Perspektiven überschritten wird. Darin liegt die kommunikative Basis posttraditioneller politischer Gemeinschaft. Politisches Handeln ist Selbstverwirklichung öffentlicher Beziehungsnetze, die sich als Wir-Identitäten begreifen können. Ebensowenig (...) wie die Individuen stehen die Netzwerke in atomistischer Isolation. Die partikularen politischen Bewegungen sind Teil eines globalen Handlungszusammenhangs. Neben die Pluralität als politischer Leitidee stellt Arendt den integrativen Impuls einer globalen Weltverantwortung. Die partikular-kulturellen Kontexte werden im Sinne der kantischen erweiterten Denkungsart auf einen menschheitlich-universalen Handlungskontext bezogen. Der Perspektivenvielfalt steht eine regulative Universalität der Weltverantwortung gegenüber, die der reflektierenden Urteilskraft überantwortet ist. So verbindet Arendt den republikanischen Partikularismus mit kantisch-universellem Weltbürgertum. (shrink)

Las primeras imágenes cinematográficas rodadas por los estadounidenses en Cuba se remontan a la Guerra Hispano cubana norteamericana, anterior al surgimiento de Hollywood y su consolidación como industria del espectáculo. Los filmes producidos en esta etapa constituyen el preámbulo del denominado cine de propaganda política que, según el historiador Román Gubern, ha llegado hasta la actualidad y, sobre todo, develan el carácter manipulador que desde sus inicios ha tenido el lenguaje cinematográfico. Entre las décadas del `30 y `40 los filmes (...) realizados por Hollywood en la isla han proyectado una imagen exótica y estereotipada sobre la identidad cubana. No solo se ha desvirtuado nuestra memoria histórica, sino también nuestros valores identitarios, imagen que se ha extendido hasta el contexto actual.En la extensa historia del cine hollywoodense no son pocas las cintas que han abordado aspectos de nuestra historia. Independientemente de la calidad de la gran mayoría de estos filmes, no se puede minimizar su importancia en el obsesivo intento por construir una imagen creíble y veraz sobre Cuba. Aunque la gran mayoría de las cintas realizadas por cineastas estadounidenses sobre la isla se encuentran limitadas por el hecho de haberse rodado en espacios y locaciones de otras naciones con semejanzas geográficas y culturales con Cuba, dicha limitación no es sinónimo de pobreza artística. El objetivo fundamental de este ensayo radica en el análisis de la representación de la imagen e identidad de Cuba en la industria de Hollywood, a partir del estallido de la Guerra Hispano-cubana-norteamericana el 15 de febrero de 1898 hasta la administración del presidente Barack Obama, período histórico conocido como el Deshielo, porque ambas naciones decidieron restablecer relaciones diplomáticas interrumpidas en plena Guerra Fría, específicamente en 1961.

Metaphysics as the foundation of science, philosophy as an exact method to discover this foundation: These are central themes in the Kant-Friesian philosophy which, at the beginning of the 20th century, Leonard Nelson, using the methods of mathematical axiomatics, further developed into interdisciplinary research programmes. Nelson carried out this research programme in his ethics but his untimely death prevented a systematic presentation of his natural philosophy and his doctrine of method. The present volume contains four transcripts of his seminars on (...) natural philosophy which he held over a period of 15 years. The transcripts, which may be taken as a comparatively complete presentation of Nelson's natural philosophy, supplement the writings published during his lifetime and convey a representative picture of his natural philosophy. // Metaphysik als Fundament der Wissenschaften, Philosophie, eine exakte Disziplin, die dieses Fundament offenlegt: Leitmotive des Kant-Fries’schen Denkgebäudes, die Leonard Nelson zu Beginn des 20. Jahrhunderts in interdisziplinäre Forschungsprogramme umsetzt. Die dabei angewandten – an der mathematischen Axiomatik ausgerichteten – Methoden haben nichts an Aktualität eingebüßt. Kann Nelson dieses Vorhaben bezüglich seiner Ethik verwirklichen, so verhindert sein früher Tod eine systematische Darstellung seiner Naturphilosophie und Methodenlehre. Der vorliegende Band enthält vier Mitschriften von Lehrveranstaltungen Nelsons. Diese Schriften, die die zu seinen Lebzeiten veröffentlichten Arbeiten zur Naturphilosophie ergänzen und erweitern sollen, decken einen Zeitraum von ca. 15 Jahren ab und geben somit einen repräsentativen Einblick in Nelsons naturphilosophisches Schaffen. Die vorliegende Zusammenstellung naturphilosophischer Nachlassschriften darf als verhältnismäßig vollständig gelten. (shrink)
