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)

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.

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

Pan es un dios peculiar en muchos aspectos. Al contrario que los restantes dioses del panteón griego, él no es antropomorfo, sino que tiene patas, cola y cuernos de carnero. Un dios con características tan arcaicas sólo puede sobrevivir confinado a la Arcadia, una región que conserva numerosos arcaísmos religiosos. Sin embargo, a partir del 490 a.C. en que se instaura su culto en Atenas, el dios comienza a cambiar. En su evolución, Pan se asimila cada vez más a Dioniso. (...) El acercamiento entre ambas figuras deja su huella en el mito, pero sobre todo en el culto. Así, un dios que en Arcadia era venerado en santuarios construidos por la mano del hombre, en el resto de Grecia recibe culto en parajes agrestes, fundamentalmente cuevas. No parece casual el hecho de que también fuera de Arcadia la gruta sea el lugar reservado a los cultos mistéricos, incluidos los dionisíacos Pan is a god peculiar in many respects. In contrast to the other gods of the Greek pantheon, he is not anthropomorphic, but he has the legs, tail and horns of a goat. These features show his age. A god like Pan can only survive in Arcadia, a region that preserves many religious archaisms. However, from 490 BC, when his cult is established in Athens, this god begins to change. In his evolution, Pan becomes increasingly assimilated the god Dionysus. The rapprochement between the two gods left his mark on the mythology, but especially in the cult of Pan. Thus, a god who was worshiped in Arcadia in sanctuaries built by men, in the rest of Greece is worshiped in wild shrines, mainly caves. Out of Arcadia, the grotto also is the place reserved for the mystery cults, including the Dionysian ones. Does not seem a coincidence. (shrink)

RESUMEN El presente trabajo de revisión expone cómo las prácticas de gestión en la anestesiología deben ser modificadas para encarar las cambiantes necesidades de pacientes, otros profesionales y sistemas sanitarios, a fin de mantener una función significativa en la atención sanitaria. Los servicios de anestesia han adoptado una amplia variedad de modelos para hacer frente a las necesidades del medio local, la relación entre los anestesiólogos y la comunidad, y los papeles desempeñados por los anestesiólogos en el tratamiento perioperatorio. El (...) sistema sanitario cubano se encuentra inmerso en un proceso de permanente adecuación de sus servicios a los problemas, demandas y necesidades de la población cubana y sus determinantes. Por ello, objetivo es exponer consideraciones teóricas en función del perfeccionamiento del servicio de Anestesiología y Reanimación. ABSTRACT This review paper presents how anesthesiology management practices must be modified in order to deal with the changing needs patients, other professionals and health systems have, in order to maintain a significant function in health care. Anesthesiology services have adopted a wide variety of models to face up to the needs the city, the relationship between anesthesiologists and the community and the role anesthesiologists play in perioperative treatment have. The Cuban health system services are in a process of permanent adaptation to the problems, demands and needs the Cuban population and its determinants have. For that reason, this paper aims at presenting theoretical considerations towards the improvement of the Anesthesiology and Resuscitation service. (shrink)

La gestión del aprendizaje es una obra que refleja el quehacer educacional de los educadores que tienen la responsabilidad de formar al ser humano en la sociedad del conocimiento, bajo la óptica de la educación críti-reflexiva que permita al humano insertarse en la sociedad eficientemente. La condición cambiante del mundo contemporáneo hace que el concepto de aprendizaje tome una dimensión más amplia y que se maneje en función del cambio en el significado de la experiencia, para que puedan desarrollarse los (...) humanos con comportamientos a la altura de los tiempos en que vivimos y no a los anteriores, en que el aprendizaje era el símbolo del que más sabía. El aprendizaje es hoy algo que esta en estrecha vinculación con la formación cognitiva, afectiva, valórica y motriz, a partir de la visión holística que se requiere para poder mirar los fenómenos desde una óptica más global que nos permita ver el proceso ante nosotros como una complejidad justo en la medida de lo que es. La gestión del aprendizaje es lo que se requiere para lograr estos propósitos. (shrink)

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)

We designed an experiment to explore the learning effectiveness of three different ways of practicing dance movements. To our surprise we found that partial modeling, called marking in the dance world, is a better method than practicing the complete phrase, called practicing full-out; and both marking and full-out are better methods than practicing by repeated mental simulation. We suggest that marking is a form of practicing a dance phrase aspect-by-aspect. Our results also suggest that prior work on learning by observation (...) and learning by mental practice may not scale up to complex movements. (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)

Resumen: Este trabajo investiga las traducciones realizadas por Aphra Behn a partir de la clasificación tripartita que estableció John Dryden entre metáfrasis, paráfrasis e imitación. Behn cultiva la metáfrasis principalmente en sus traducciones de La Rochefoucauld, la paráfrasis en las versiones de Cowley o Tallemant, entre otros; mientras que aplica la imitación a las Fábulas de Esopo. Se constata que Behn rompe con la tradición de traducir principalmente a los autores clásicos, ensanchando los cauces de entrada de literatura moderna en (...) Inglaterra y ampliando las posibilidades de la traducción literaria. Analizando unas muestras, se infiere la manipulación del texto original que la autora realiza en ocasiones, en consonancia con su ideario creativo, generando un texto meta provisto de nuevas resonancias de género y políticas contextualizadas en su época. Asimismo, se deduce que la escritora profesional de la Restauración cultiva la traducción movida, entre otros motivos, por los gustos del naciente mercado literario en cuanto a las novedades del país galo y, por tanto, motivada por un afán comercial.: This paper examines the translations by Aphra Behn based on the tripartite classification that John Dryden established between metaphrase, paraphrase and imitation. Behn employs mainly metaphrase in her translations of La Rochefoucault; paraphrase in her versions of Cowley and Tallemant, among others; while applying the imitation to Aesop's Fables. It is found that Behn breaks with the tradition of translating principally classical authors, broadening channels for the entrance of modern literature into England and expanding the possibilities of literary translation. Analyzing the samples, the author's occasional manipulation of the original text is identified, consonant with her creative ideas and generating a metatext featuring new political and gender resonances contextualized in her era. It is also concluded that the professional writer of the Restoration employs translation spurred by the tastes of the burgeoning literary market, among other factors, shaped by recent developments in France and, as such, motivated by commercial interests.

Whether the prefrontal cortex is part of the neural substrates of consciousness is currently debated. Against prefrontal theories of consciousness, many have argued that neural activity in the prefrontal cortex does not correlate with consciousness but with subjective reports. We defend prefrontal theories of consciousness against this argument. We surmise that the requirement for reports is not a satisfying explanation of the difference in neural activity between conscious and unconscious trials, and that prefrontal theories of consciousness come out of this (...) debate unscathed.

Cognitive dysfunction in Alzheimer’s disease is caused by disturbances in neuronal circuits of the brain underpinned by synapse loss, neuronal dysfunction and neuronal death. Amyloid beta and tau protein cause these pathological changes and enhance neuroinflammation, which in turn modifies disease progression and severity. Vagal nerve stimulation, via activation of the locus coeruleus, results in the release of catecholamines in the hippocampus and neocortex, which can enhance synaptic plasticity and reduce inflammatory signalling. Vagal nerve stimulation has shown promise to enhance (...) cognitive ability in animal models. Research in rodents has shown that VNS can have positive effects on basal synaptic function and synaptic plasticity, tune inflammatory signalling, and limit the accumulation of amyloid plaques. Research in humans with invasive and non-invasive VNS devices has shown promise for the modulation of cognition. However, the direct stimulation of the vagus nerve afforded with the invasive procedure carries surgical risks. In contrast, non-invasive VNS has the potential to be a broadly available therapy to manage cognitive symptoms in early AD, however, the magnitude and specificity of its effects remains to be elucidated, and the non-inferiority of the effects of non-invasive VNS as compared with invasive VNS still needs to be established. Ongoing clinical trials with healthy individuals and patients with early AD will provide valuable information to clarify the potential benefits of non-invasive VNS in cognition and AD. Whether invasive or non-invasive VNS can produce a significant improvement on memory function and whether its effects can modify the progression of AD will require further investigation. (shrink)

In 1944 Hans Reichenbach developed a three-valued propositional logic (RQML) in order to account for certain causal anomalies in quantum mechanics. In this logic, the truth-value _indeterminate_ is assigned to those statements describing physical phenomena that cannot be understood in causal terms. However, Reichenbach did not develop a deductive calculus for this logic. The aim of this paper is to develop such a calculus by means of First Degree Entailment logic (FDE) and to prove it sound and complete with respect (...) to RQML semantics. In Section 1 we explain the main physical and philosophical motivations of RQML. Next, in Sections 2 and 3, respectively, we present RQML and FDE syntax and semantics and explain the relation between both logics. Section 4 introduces \(\varvec{\mathcal {Q}}\) calculus, an FDE-based tableaux calculus for RQML. In Section 5 we prove that \(\varvec{\mathcal {Q}}\) calculus is sound and complete with respect to RQML three-valued semantics. Finally, in Section 6 we consider some of the main advantages of \(\varvec{\mathcal {Q}}\) calculus and we apply it to Reichenbach’s analysis of causal anomalies. (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.
