Desde 1980 têm-se feito discussões, na Universidade Federal de Uberlândia, para mudar o sistema de avaliação. Em diversas ocasiões, foram feitas consultas a diversas instância da comunidade sobre o quê e em que todas as vezes a discussão ficou retida em algum ponto sem que houvesse um progresso, nos passos seguintes. A rigor, a única mudança visível em todo esse período foi a eliminação das provas finais do semestre. A discussão sobre a alteração da nota mínima de aprovação, de 54 (...) para 60 ou 70 pontos foi marcada, em 83 e 84, por um artificialismo em torno de um valor aleatório que pudesse significar um maior rigor ou grau de exigência desejável. Um dos argumentos que emergiam, na época, foi o de que um aluno da UFU estaria em desigualdade de condições de competição, ao concorrer por uma vaga no mercado de trabalho, quando comparado com algum aluno de outra Universidade que tivesse um grau de exigência maior.

Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) (...) logic programs. It turns out that none of the existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle. (shrink)

O objectivo do presente artigo é apresentar as ideias que o físico teórico austríaco Ludwig Boltzmann (1844-1906) desenvolveu acerca da natureza e do papel das leis do pensamento. Muito influenciado por Charles Darwin, Boltzmann recusou-se a compreender as leis do pensamento segundo a filosofia de Kant. Em particular, Boltzmann defendeu uma concepção evolutiva das leis do pensamento. O artigo mostra de que forma a concepção das leis do pensamento aceite por Boltzmann impôs uma transformação da sua ideia sobre aquilo que (...) seria o próprio da filosofia. /// Aim of this article is to show some of the epistemological ideas developed by Ludwig Bolzmann (1844-1906). The author of the article considers in particular Bolzmann's view on the nature and role of the laws of reason in the construction of scientific theories. Moreover, he also analyses the influence of Charles Darwin on the Austrian theoretical physicist and how this influence can be viewed as the turning point for the definition of Boltzmann's conception of philosophy.

O objetivo deste ensaio consiste em argumentar, de maneira não conclusiva, em favor da tese que responsabiliza a física nuclear pela popularização, entre os físicos, do termo ‘modelo’. Apesar de este termo já ser usado desde, pelo menos, o início do século XX, foi com as investigações sobre a estrutura do núcleo atômico que ele se disseminou. Finalmente, este texto questiona se a popularização deste conceito não poderia ser também explicada pela sua capacidade de permitir a uma ciência tão especializada, (...) donde tão fragmentada, como a física a existência de canais de comunicação internos.

O tema central desta monografia é a noção de realidade, tal como esta foi entendida por alguns cientistas naturais da primeira metade do século XX. Os cientistas-filósofos escolhidos são: Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger e Max Born. À guisa de comentário introdutório, devo observar que o tema da realidade não é o único aqui abordado, e que a presente monografia pode ser tomada como uma primeira introdução às ideias e teses filosóficas dos seis cientistas referidos. (...) Ao escrever este trabalho, o meu principal objetivo foi o de fazer com que os estudantes de graduação dos cursos de filosofia tenham a possibilidade de ler um comentário geral sobre as ideias filosóficas – em particular, as metafísicas, portanto referentes à natureza da realidade – de alguns dos físicos mais importantes do século passado. Um segundo público alvo possível pode ser encontrado entre os estudantes do ensino médio. Finalmente, este texto pode, eventualmente, ser definido como paradidático, atraindo a atenção de professores, principalmente daqueles que atuam neste último segmento. (shrink)

Esta introdução descreve os mais importantes dados biográficos da vida e da obra do físico teórico austríaco Ludwig Boltzmann (1844-1906). As principais contribuições científicas de Boltzmann situam-se nos domínios da teoria cinética dos gases e mecânica estatística, da qual ele foi um dos fundadores. A tese de que as teorias científicas são representações dos fenômenos naturais é encontrada em todos os artigos de Boltzmann. No verbete "modelo", ela é apresentada de modo mais organizado, o que o torna uma peça fundamental (...) para a compreensão do pensamento filosófico do físico austríaco. O verbete, publicado na famosa enciclopédia Britannica, foi escrito para o público em geral. Ainda assim, Boltzmann não se eximiu de tomar partido em favor do uso de modelos. Estes últimos não apenas seriam inevitáveis, mas necessários, uma vez que tornavam possível o aperfeiçoamento contínuo da ciência. This introduction describes the most important biographical details of the life and work of the Austrian theoretical physicist Ludwig Boltzmann (1844-1906). The main scientific contributions of Boltzmann can be found in areas such as the kinetic theory of gases and statistical mechanics, of which he was one of the co-founders. The thesis that scientific theories are representations of natural phenomena is found in all philosophical articles by Boltzmann. In the entry "model", published in the celebrated Encyclopedia Britannica, the thesis is presented in a more organized way, making it the keystone to understand the philosophical thought of the Austrian physicist. Although the entry was written for the general public, in it Boltzmann did not refrain from taking sides as far as the use of models is concerned. According to him, the latter would not only be inevitable, but in fact necessary, since they would made possible the continuous improvement of science. (shrink)

Este artigo destina-se a introduzir a conferência de Heisenberg "A doutrina goethiana e newtoniana das cores à luz da física moderna", proferida em 1941, cuja tradução é aqui publicada. Analisa-se primeiramente o projeto filosófico de uma ordenação da realidade, desenvolvido pelo físico no início da década de 1940, o qual subjaz à discussão sobre as doutrinas das cores em Goethe e Newton. No segundo momento, faz-se uma exposição de algumas das implicações filosóficas da teoria quântica, com ênfase na interpretação da (...) assim denominada escola de Copenhague. Por fim, procura-se mostrar como a querela entre Goethe e Newton é utilizada para defender as abstrações da física teórica dos ataques da assim denominada "física ariana" e, ao mesmo tempo, preservar o valor das considerações intuitivas de Goethe. This paper aims at exposing the Heisenberg's conference "The teachings of Goethe and Newton on colors in the light of modern physics", presented in 1941, whose translation is presented here. In the first place the paper analyzes the philosophical project of an ordination of the reality, developed by the physicist in the early 1940s and which is the basis for the discussion of the "Teachings of Goethe and Newton on colors". Secondly it exposes some philosophical implications of the quantum theory by emphasizing the point of view of the Copenhagen school. Finally, it shows how the dispute between Goethe and Newton is exploited to defend the abstractions of the theoretical physics against the attacks of the so called "German physicists" and, at the same time, to preserve the worth of the Goethe's intuitive analysis.

This article defends the hypothesis that Ernst Mach employed naturalism — an attitude which has its origin in Mach’s acceptance of Darwinism — as a weapon against metaphysics, since the former would try to establish evalutions criteria, including those necessary to choose scientific theories, capable of being used by human beings.

The purpose of the article is to present the ideas that the Austrian physicist Ludwig Boltzmann developed on the role of classical mechanics in physics. He had elaborated them at a time when classical mechanics began to be considered as not being any more the ground for all other physical theories. Boltzmann never accepted this conclusion. He rejected it, developing at the same time some ideas on the epistemological nature of scientific theories. According to him, scientific theories are representations of (...) natural phenomena.

Este artigo pretende apresentar uma discussão sobre a possibilidade de identificarmos as possíveis contribuições das viagens de descobrimento, enfatizando as navegações portuguesas, para a construção do pensamento científico moderno. Por um lado, é analisado o valor da experiência direta valorizada pelos portugueses como critério de certeza acerca das afirmações sobre o mundo geográfico que acabaram por colocar em questão a concepção de mundo difundida a partir dos clássicos antigos – os gregos – e, por outro lado, é apresentado uma concepção (...) de ciência moderna que comporta as contribuições dos chamados homens práticos, como os navegadores, cuja atividade marítima promove um debate, no campo da geografia e cartografia sobre a própria constituição do mundo, sem, contudo, romper definitivamente com a tradição cosmológica. A nossa análise é realizada por meio de uma discussão crítica com a historiografia existente. (shrink)

O problema da causação descendente é um ponto central na formulação do fisicalismo não-redutivo e na compreensão da emergência de propriedades. Duas interpretações possíveis da causação descendente, nas quais a contribuição do pensamento aristotélico é importante, são examinadas. Os requisitos do programa de matematização da natureza na mecanica clássica, que levaram ao abandono de três dos modos causais aristotélicos, nao parecem igualmente importantes nas ciencias especiais. Isto sugere que a contribuição de Aristóteles pode ser, de certa maneira, retomada. Uma definição (...) de propriedade emergente é apresentada, sendo a causação descendente interprerada de acordo com os modos causais formal e funcional.The problem of downward causation is a key subject in the formulation of nonreductive physicalism as well as in the understanding of property emergence. Two possible interpretations of downward causation, to which Aristotelian thought is relevant, are examined. In the mathematical understanding of nature in classical mechanics, the principle of causality should meet requirements that entailed the rejection of three among the four Aristotelian causal modes. Those requirements do not seem equally important in the special sciences and one may suggest, then, that Aristotle’s contribution may be taken into account. A definition of an emergent property is proposed, in which downward causation is interpreted according to the formal and functional causal modes. (shrink)

O objectivo primário do presente artigo é estudar algumas das implicações, sobretudo epistemológicas, associadas com o auto-intitulado movimento da Física Ariana (Deutsche Physikj, movimento esse que aqui se considera como tendo sido iniciado pelos físicos, laureados com o Prémio Nobel, Philipp Lenard e Johannes Stark. Assim, em primeiro lugar, procura-se analisar questões como a da ligação entre ciência e raça, a da função do método experimental e do método dedutivo nas descobertas das ciências naturais, bem como a da relação entre (...) matemática e natureza, já para não mencionar a dimensão histórica da ciência. Em vez de recorrer a conceitos supostamente puros do que sejam ciência ou racionalidade em ordem a instaurar um tribunal da história, cujo veredicto seria a condenação da Física Ariana como irrisória anomalia epistemológica no corpo histórico da ciência, os autores do presente artigo procuram, antes de mais, traçar a origem do movimento a partir das biografias de Lenard e Stark, acreditando que o carácter profundamente conturbado de ambos, coadunado com a conflituosa situação política que antecedeu a ascensão de Hitler ao poder na Alemanha em 1933, seriam razões suficientes para a formação das doutrinas que atacavam a Física Teórica. Nesse sentido, depois de expor os princípios e as ideias defendidas pelos físicos arianos, os autores procuram evidenciar até que ponto uma análise restrita ao campo da física e dos seus documentos não é suficiente para uma compreensão cabal de tal movimento. Ao mesmo tempo, procuram mostrar também por que razão é necessário considerar que algumas objecções levantadas contra a física teórica se constituíam como problemas verdadeiramente relevantes, sendo que alguns deles foram também formulados por autores que não pactuavam com as convicções políticas de Lenard e Stark. Finalmente, o artigo comporta uma análise das posições defendidas por Werner Heisenberg em ordem a mostrar a seriedade com a qual as críticas dos físicos arianos foram recebidas por este autor, nelas reconhecendo algo digno de ser respondido, e isso não meramente por razões políticas, mas antes porque constituíam dilemas reais instalados na prática das ciências naturais. Ou seja, recorrendo aos argumentos esgrimidos por Werner Heisenberg, os autores do artigo pretendem demonstrar que a Física Ariana não merece atenção apenas na sua qualidade de aberração histórica, mas também pelo facto de ela ter levantado questões ainda hoje epistemologicamente relevantes. /// The primary aim of the present article is to study some of the implications, particularly the epistemological ones, associated with the movement of the so called German Physics (Deutsche PhysikJ, a movement that in this article is mainly associated with the work of the physicists, and Nobel laureates, Phillip Lenard and Johannes Stark. The article begins by analyzing questions related to the connection established between science and race, as well as to the function of the experimental and deductive methods in the discoveries of the natural sciences, not to mention the problems associated with the relation between mathematics and nature as well as the historical dimension of science. The goal, therefore, is not to take supposedly pure concepts about what science and rationality might be and establish them as judges in the tribunal of history, whose verdict would be the condemnation of the German Physics as an insignificant epistemological anomaly within the historical body of science. Rather, the authors of the article want to trace the origin of the movement of the German Physics by reading the biographies of Lenard and Stark, whereby it is assumed that the problematic character of these physicists together with the political situation that anteceded Hitlers ascension to power in Germany in 1933 would be reason enough for the formation of doctrines directed against theoretical physics. In this sense, after expounding the principles and the doctrines defended by the Arian physicists, the authors of the article show that an analysis circumscribed to the domain of physics would not be sufficient for a global understanding of this movement. At the same time, however, the authors also want to show the reason why it is necessary to consider some of the objections raised against theoretical physics as serious problems, even though some of them were also formulated by authors that did not share the political convictions of Lenard and Stark. Finally, the article contains an analysis of the positions defended by Werner Heisenberg in order to demonstrate the seriousness with which the criticisms of the Arian physicists were received by this most important author, so much so that he recognized in them something worth a response, and this not only for political reasons, but also because he recognized the problems raised as a dilemma situated at the very heart of the practice of the natural sciences. In other words, by a close reading of the arguments presented by Werner Heisenberg, the authors of the article want to demonstrate that the movement of German Physics is worth attention not only in its quality as an historical aberration, but also due to the fact that it raised questions that are still epistemologically relevant.

Este artigo descreve o modo pelo qual a noção de modelo começou a ingressar na ciência, em particular na física, no final do século XIX. Este é talvez o primeiro domínio científico a fazer uso explícito e consciente dessa noção, para o qual o uso de modelos significou o abandono de toda e qualquer tentativa de representar fielmente os fenômenos naturais. Em questão, estava a representação dos fenômenos elétricos e magnéticos por meio de analogias. This article describes the way in (...) which the idea of model began to be discussed in science, in particular in physics, towards the end of the 19th century. Physics is perhaps the first scientific domain that explicitly and consciously made use of models in a way that was understood to involve abandoning any attempt faithfully to represent natural phenomena. The representation of electromagnetic phenomena by means of analogies was in question. (shrink)

Through the analysis of the thought of Mach and Duhem, who have felt the need to re-evaluate the relationship between metaphysics and physics, we study in what measure the authors had a position relating to an eventual weakening of the traditional epistemic criteria, which were until their time used for the evaluation of scientific theories, and those criteria should respect the distinction between fact and value. We investigate the way each argues for a division between science and metaphysics, as well (...) as the reasons for this. For both authors, adopting mechanicism as the basis for modern science is in the origin of the emergence of the materialist metaphysics, which should now be abandoned. Every metaphysics built from physical results would be a disrespect to the distinction between fact and value. Duhem and Mach argue for a new role for the common sense, which should not be taken as the source of error anymore. (shrink)

Defendemos que o realismo os físicos, com diferentes graus de conhecimento e elaboração filosófica, assumem o realismo científico como seu pressuposto metafísico. Argumentamos que há uma imbricação entre pressupostos metafísicos e princípios axiológicos. Assim, o realismo científico não (...) se faz notar somente nas teorias físicas. Ele está presente também no nível das práticas e dos valores, ou seja, do ethos da comunidade dos físicos. (shrink)

The (...) chapters of this volume are forwarded by a general introduction, which aims to sketch not only the contents of the chapters, but it is conceived as a historical and conceptual guide to the development of the field in Brazil. The introduction intends to be useful to the reader, and not only to the specialist, helping them to evaluate the increase in production of this country within the international context. (shrink)

According to Steven Weinberg, it is the goal of elementary particle physics to search for the final laws of physics, i.e. a simple set of principles from which everything we know about physics can be derived. The main criterion that guides the search for such a set of principles is, according to the author, the sense of inevitability of physical theories, which Weinberg conflates with the idea of beauty. The theoretical physicists’ task is, in this sense, to look for constraining (...) principles, such as symmetries and renormalizability, that increase the sense of inevitability of physical laws. It is the goal of this paper to discuss Weinberg’s arguments in favor of reductionism, as well as his conception of final theory and the associated concept of “inevitability.”. (shrink)

Introduction: The actions taken by the government to deal with the consequences of the coronavirus diseases 2019 pandemic caused different levels of restriction on the mobility of the population. The need to continue offering physical exercise to individuals after stroke became an emergency. However, these individuals may have barriers to adhere to the programs delivered remotely. There is a lack of evidence related to adherence, attendance, safety, and satisfaction of remote exercise programs for this population.Objective: The aim was to evaluate (...) adherence and barriers to attend a remote physical exercise program for individuals after stroke. We aimed to identify adherence and attendance rate of the remote physical exercise program ; to identify the safety of a remote physical exercise program ; and to identify the overall experience to participate in a remote program.Materials and methods: This is a longitudinal study, including 36 stroke survivors who already attended a face-to-face physical exercise program prior to the COVID-19 pandemic. The remote physical exercise program included sessions for 2 days/week for a duration of 22 weeks, with a total of 44 sessions, which were delivered asynchrony via recorded video sessions. As outcome measures, we performed two questionnaires to identify attendance, barriers, safety, and overall experience related to the program.Results: The adherence rate was 86. The attendance rate was 19, with a total of 8 sessions. The main barriers for lower attendance rate were as follows: lack of motor skills and physical fitness to workout in 80 reports, followed by no exercise companion in 44 reports. The remote physical program has been shown to be safe, and the overall experience was positive from the perspectives of the participants and the family members.Conclusion: Although the adherence rate was high, the attendance rate was low on the remote physical exercise program. The main barriers to attending the program remotely reflect the need of tailoring individually an asynchrony mode of delivering the sessions to individuals after stroke. Our results also indicate how the COVID-19 impacted the health conditions of stroke survivors. The program was safe, and the overall experience indicated a change in the mental, physical, and social health of individuals after stroke and their family members. (shrink)

In this paper we will present the philosopher Friedrich Nietzsche’s main reflections on the scientific enterprise, its relation to the metaphysical tradition, and how the German author drew on the nineteenth century cosmological discussion to develop a worldview that ultimately endorses a dynamic and more creative form of science, whose representations and values should not be separated from human interests.

This article describes and discusses the ideas of Patrick Heelan about the nature of visual perception, which he argues as not being intrinsically Euclidian, but rather as being described both in Euclidian and not-Euclidian geometries. Another objective is to place Heelan’s ideas in the context of the attempts to grasp the nature of science from the hermeneutical standpoint, in agreement with the so called analytical philosophy of science, noticing that his philosophical perspective is determined by phenomenology, in particular that inspired (...) by Heidegger. Heelan’s phenomenology and philosophy of science are innovative and original deserving to be described and analysed. It is proposed that the investigation of Heelan’s project opens up new perspectives in both phenomenology and philosophy of science. (shrink)

Ionizing radiation is present in various situations in the contemporary world. Defining the quantities and units for this field is a complex scientific task, especially the quantities used in radiological protection (RP) to estimate the damage caused to individuals exposed to radiation (detriment). This article highlights the lack of consensus in the scientific RP community regarding the quantities and units employed in practice from the perspective of the philosophy of science. The basic concepts related to the system of quantities are (...) presented, followed by the problems and criticisms addressed by experts in the field. Several reasons for these problems are identified. The article discusses the scant interest on the part of philosophy of science in RP. The philosophy of science is still dominated by an analytical–conceptual perspective that pays little attention to the actual influence of certain structures better understood when considered from the institutional viewpoint, which is here exemplified by the International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA).

The growth of urban violence in Brazil, as in other countries, has led citizens to demand more severe and punitive measures to solve the problem of juvenile crime. One motion submitted to the Brazilian parliament, for instance, proposes to reduce the age of penal majority from 18 to 16 years. Our hypothesis is that popular opinions about this proposal are largely constrained by construal levels and psychological distance. Accordingly, we expect that the knowledge and proximity to the circumstances associated with (...) juvenile transgression will influence opinions about the proposal. To test this hypothesis, we evaluated how opinion against or for the proposal can be explained by psychological distance and moral development theory. We studied two samples, composed of people who do not have a deep experience with the subject and workers from a juvenile justice court. After collecting socio-demographic information from the subjects and their answer to moral dilemmas, the data was subjected to a multivariate analysis by multimodal logistic regression for socio-demographic characteristics, Kohlberg moral stages, and opinion on the reduction of APM as dependent variables. Our findings suggest that 1) opinion about the APM depends on psychological distance and 2) socioeconomic variables may influence the average construal level of adolescent transgressors in the public’s perspective.

Este artigo tem como objetivo discutir algumas das teses centrais do físico teórico e epistemólogo John Michael Ziman relativas à dimensão social da ciência. Ziman sustenta que, para um melhor entendimento das mudanças ocorridas na prática científica contemporânea, sobretudo das consequências geradas nas últimas décadas pelo que ele denominou de "ciência pós-acadêmica", é necessária uma abordagem que inclua aspectos não somente filosóficos, mas também sociológicos e históricos. Segundo Ziman, a supervalorização, na ciência pós-acadêmica, de valores ligados a uma cultura gerencial (...) tem como consequências, a curto prazo, a alteração do éthos mertoniano e dos princípios filosóficos utilizados historicamente pelos cientistas como ideais reguladores; e, a longo prazo, a redução da capacidade cognitiva da ciência de produzir "novos mapas" da realidade. Ao analisar alguns conceitos-chave da obra de Ziman, tais como "consensibilidade", "consensualidade", "conhecimento público" e "ciência pós-acadêmica", esperamos debater a concepção de ciência desse autor, ainda pouco citado no Brasil. The main objective of this article is to discuss some of the central theses on the work of the physicist and epistemologist John Michael Ziman concerned with the social dimension of science. Ziman supports the thesis that in order to have a better understanding of the recent changes in scientific practice, especially the consequences brought by a new mode of knowledge production, in the last decades, which he names "post-academic", it is necessary a new methodological approach is necessary that includes, not only philosophical aspects, but also sociological and psychological ones. According to Ziman, one of the consequences of the overvaluation of a managerial culture in post academic science is, in the short term, the deflation of the Mertonian ethos and also of the philosophical principles which were historically shared amongst scientists as regulatory ideals; and in the long run, the major consequence of post-academic science would be the reduction of cognitive capacity of science to produce "new maps" of the world. By the analysis of some key-concepts in Ziman's work, such as "consensibility", "consensuality", "public knowledge" and "post-academic science", we aim to make the Brazilian reader acquainted with his conception of science.

The use of transcranial Electrical Stimulation in the modulation of cognitive brain functions to improve neuropsychiatric conditions has extensively increased over the decades. tES techniques have also raised new challenges associated with study design, stimulation protocol, functional specificity, and dose-response relationship. In this paper, we addressed challenges through the emerging methodology to investigate the dose-response relationship of High Definition-transcranial Direct Current Stimulation, identifying the role of negative valence in tinnitus perception. In light of the neurofunctional testable framework and tES application, (...) hypotheses were formulated to measure clinical and surrogate endpoints. We posited that conscious pairing adequately pleasant stimuli with tinnitus perception results in correction of the loudness misperception and would be reinforced by concurrent active HD-tDCS on the left Dorsolateral Prefrontal Cortex. The dose-response relationship between HD-tDCS specificity and the loudness perception is also modeled. We conducted a double-blind, randomized crossover pilot study with six recruited tinnitus patients. Accrued data was utilized to design a well-controlled adaptive seamless Bayesian dose-response study. The sample size and optimum interims were anticipated for adaptive decision-making about efficacy, safety, and single session dose parameters. Furthermore, preliminary pilot study results were sufficient to show a significant difference within the longitudinally detected self-report tinnitus loudness between before and under positive emotion induction. This study demonstrated a research methodology used to improve emotion regulation in tinnitus patients. In the projected method, positive emotion induction is essential for promoting functional targeting under HD-tDCS anatomical specificity to indicate the efficacy and facilitate the dose-finding process. The continuous updating of prior knowledge about efficacy and dose during the exploratory stage adapts the anticipated dose-response model. Consequently, the effective dose range to make superiority neuromodulation in correcting loudness misperception of tinnitus will be redefined. Highly effective dose adapts the study to a standard randomized trial and transforms it into the confirmatory stage in which active HD-tDCS protocol is compared with a sham trial. Establishing the HD-tDCS intervention protocols relying on this novel method provides reliable evidence for regulatory agencies to approve or reject the efficacy and safety. Furthermore, this paper supports a technical report for designing multimodality data-driven complementary investigations in emotion regulation, including EEG-driven neuro markers, Stroop-driven attention biases, and neuroimaging-driven brain network dynamics.

AimTo evaluate the cognitive functioning of subjects practicing trance mediumship in Brazil.MethodThe study was based on the measurement of cognitive functions of 19 spirits mediums through neuropsychological tests such as the Brief Cognitive Screening Battery, the Verbal Fluency Test, the digit span test, the cube test, the five digit test and an evaluation of mental health through scales such as the Beck Depression Inventory, the Self-Report Questionnaire, and the Trauma History Questionnaire. The sample included the participation of spirit mediums divided (...) into two groups. The more experienced group with 11 subjects had more than 10 years of mediumistic practice, while the other less experienced group with 8 subjects had 1–5 years of experience. The inclusion criteria were psychophonic mediums with regular trance practices for at least one year. The data collected were analyzed using the SPSS statistical package.ResultsRegarding performance on the BCSB and digit span test, all subjects reached scores at the median or higher in comparison to standardized scores of Brazilians. Scores of 90% on the cube test and 42% on the FAS were reached in comparison to median or higher values, versus the median of standardized scores among Brazilians. On the FDT, we found statistical significance in the choice stage, with higher performance of subjects whose initial age of trance recognition occurred before 21 years old. On the BDI scale, no participant met the criteria for major depression. The SRQ showed an incidence of common mental disorders in 21% of the sample, which was more prevalent in the LEG.ConclusionThe cognitive functioning of subjects who practice trance mediumship in Brazil is associated with cognitive health. Executive dysfunction may be a tendency in LEG. However, an incidence of common mental disorders in the LEG was observed. Executive processing was higher in the subgroup with early practices of recognizing the phenomenon. (shrink)
