Error-related electroencephalographic signals have been widely studied concerning the human cognitive capability of differentiating between erroneous and correct actions. Midfrontal error-related negativity and theta band oscillations are believed to underlie post-action error monitoring. However, it remains elusive how early monitoring activity is trackable and what are the pre-response brain mechanisms related to performance monitoring. Moreover, it is still unclear how task-specific parameters, such as cognitive demand or motor control, influence these processes. Here, we aimed to test pre- and post-error EEG (...) patterns for different types of motor responses and investigate the neuronal mechanisms leading to erroneous actions. We implemented a go/no-go paradigm based on keypresses and saccades. Participants received an initial instruction about the direction of response to be given based on a facial cue and a subsequent one about the type of action to be performed based on an object cue. The paradigm was tested in 20 healthy volunteers combining EEG and eye tracking. We found significant differences in reaction time, number, and type of errors between the two actions. Saccadic responses reflected a higher number of premature responses and errors compared to the keypress ones. Nevertheless, both led to similar EEG patterns, supporting previous evidence for increased ERN amplitude and midfrontal theta power during error commission. Moreover, we found pre-error decreased theta activity independent of the type of action. Source analysis suggested different origin for such pre- and post-error neuronal patterns, matching the anterior insular cortex and the anterior cingulate cortex, respectively. This opposite pattern supports previous evidence of midfrontal theta not only as a neuronal marker of error commission but also as a predictor of action performance. Midfrontal theta, mostly associated with alert mechanisms triggering behavioral adjustments, also seems to reflect pre-response attentional mechanisms independently of the action to be performed. Our findings also add to the discussion regarding how salience network nodes interact during performance monitoring by suggesting that pre- and post-error patterns have different neuronal sources within this network.

Introduction: The potential therapeutic efficacy of real-time fMRI Neurofeedback has received increasing attention in a variety of psychological and neurological disorders and as a tool to probe cognition. Despite its growing popularity, the success rate varies significantly, and the underlying neural mechanisms are still a matter of debate. The question whether an individually tailored framework positively influences neurofeedback success remains largely unexplored.Methods: To address this question, participants were trained to modulate the activity of a target brain region, the visual motion (...) area hMT+/V5, based on the performance of three imagery tasks with increasing complexity: imagery of a static dot, imagery of a moving dot with two and with four opposite directions. Participants received auditory feedback in the form of vocalizations with either negative, neutral or positive valence. The modulation thresholds were defined for each participant according to the maximum BOLD signal change of their target region during the localizer run.Results: We found that 4 out of 10 participants were able to modulate brain activity in this region-of-interest during neurofeedback training. This rate of success is consistent with the neurofeedback literature. Whole-brain analysis revealed the recruitment of specific cortical regions involved in cognitive control, reward monitoring, and feedback processing during neurofeedback training. Individually tailored feedback thresholds did not correlate with the success level. We found region-dependent neuromodulation profiles associated with task complexity and feedback valence.Discussion: Findings support the strategic role of task complexity and feedback valence on the modulation of the network nodes involved in monitoring and feedback control, key variables in neurofeedback frameworks optimization. Considering the elaborate design, the small sample size here tested impairs external validity in comparison to our previous studies. Future work will address this limitation. Ultimately, our results contribute to the discussion of individually tailored solutions, and justify further investigation concerning volitional control over brain activity. (shrink)

Este artigo tem como objetivo promover uma reflexão sobre as potências de performances protagonizadas por mulheres gordas na rede social digital Instagram, a partir de pesquisas bibliográfica, documental e de campo. Faz-se uma leitura multidisciplinar de corpos gordos, particularmente o de mulheres, em imagens postadas por elas na rede, no sentido de pensarmos formas outras de representação e de re-existência daqueles corpos que são tratados como doentes, feios, fracassados e distantes do ideal de feminilidade, no seio social e propagado também (...) pela mídia hegemônica. Articulam-se saberes de forma transdisciplinar em prol da discussão sobre corpos, performances e problematizações do eu no espaço artístico e comunicacional, bem como refletindo acerca de caminhos possíveis na comunicação e cultura visual em perspectivas em gênero.

Autonomous weapons are systems that, once activated, can identify, select and engage targets by themselves. Scharre (2018. Army of None: Autonomous Weapons and the Future of War. New York: Norton) has given a definition of autonomy based on three dimensions: the automatized tasks, the relationship with the human user and the sophistication of the machine’s decision-making process. Based on this definition of autonomy, this article provides an overview of systematic biases that may occur in each of these three dimensions. Before (...) the deployment of autonomous systems in war it is important to know how various biases can affect the functioning of the machines and how these biases can be compensated for. (shrink)

A critical analysis of Kelsen’s theory leads to a broad concept of custom, which covers diverse types of customary norms, where the always required conviction of legal bindingness depends on different types of factual and normative reasons. In it we should include a strict concept of custom or legal usage, derogating custom, custom of general international law, custom that establishes an unwritten constitution, custom that establishes a new written constitution, judicial custom which creates a rule of precedent and custom newly (...) expressed in the judicial application of customary rules. The basic norm could be formulated as a constitutive norm: ‘If the norms created through the first historical constitution are effective, then the first historical constitution are valid.’ It is thus a customary constitutive rule that recognizes the first historical constitution as valid law. Norms which establish sources of law are constitutive rules, they can be customary norms or legislated norms, but if they are legislated, they have their validity recognized by, directly or indirectly, a constitutive customary norm. By using a broad concept of custom as a conventional practice, Hart implies that general recognition of a customary rule, together with the practice that accompanies it, are sufficient conditions of validity. A doctrine of recognition that is arrived at by means of criticism and a rational reconstruction of the doctrines of Kelsen and Hart regains the essential theses of the traditional recognition theory of Bierling and Engisch.

Open peer commentary on the article “Design Research as a Variety of Second-Order Cybernetic Practice” by Ben Sweeting. Upshot: I claim that the parallels between design research, second-order cybernetics and second-order science, as discussed by Sweeting in the target article, are more explicit in digital design. The discussion of SOC and SOS can point towards the creation of an epistemological foundation to digital design, where self-reflexivity and the inclusion of the observer are central questions.

In both biology and psychology, the notion of an individual is indispensable yet puzzling. It has played a variety of roles in diverse contexts, ranging from philosophical problems of personal identity to scientific questions about the immunological mechanisms for telling ‘self’ from ‘non-self.’ There are notorious cases in which the question of individuality is difficult to settle — ant hill, slime mold, or beehive, for instance. Yet the notion of an individual organism, both dependent on and independent of other individuals (...) in specific ways, is crucial to our conception of life itself. It is also crucial to our notion of mentality, and hence to other concepts — moral and social — which must be explicated in terms of individual mentality. (Think, for example, of the importance of the quality and nature of individual consciousness to debates about abortion and euthanasia.). (shrink)

During its century-long unfolding, spreading in numerous directions, Husserlian phenomenology while loosening inner articulations, has nevertheless maintained a somewhat consistent profile. As we see in this collection, the numerous conceptions and theories advanced in the various phases of reinterpretations have remained identifiable with phenomenology. What conveys this consistency in virtue of which innumerable types of inquiry-scientific, social, artistic, literary – may consider themselves phenomenological? Is it not the quintessence of the phenomenological quest, namely our seeking to reach the very foundations (...) of reality at all its constitutive levels by pursuing its logos? Inquiring into the logos of the phenomenological quest we discover, indeed, all the main constitutive spheres of reality and of the human subject involved in it, and concurrently, the logos itself comes to light in the radiation of its force (Tymieniecka).

En este artículo se desarrolla la hipótesis de que el conocimiento de la sustancia pensante en las Meditaciones sobre la filosofía primera y en Objeciones y Respuestas no es claramente explicitado por René Descartes. Se entiende que tal exposición es necesaria para una comprensión integral delestatus de la filosofía cartesiana en el momento de redactar las Meditaciones y, principalmente, paraasimilar cómo concebía Descartes el conocimiento de la sustancia pensante en los años 1641 y 1642.El conocimiento de la sustancia pensante es, (...) como se sabe, un elemento fundamental para toda la filosofía cartesiana. Para ello, se recurre, primeramente, a los dos modos en que Descartes presentael conocimiento de la sustancia pensante en las Meditaciones, destacando los problemas que cadauno de estos conlleva. Posteriormente, a partir de las Objeciones y Respuestas, principalmentela quinta y la séptima, se presenta las críticas de Pierre Gassendi y Pierre Bourdin sobre elconocimiento de la sustancia pensante. Tanto Gassendi como Bourdin subrayan que el texto deMeditaciones no es suficiente para esclarecer de qué manera la sustancia pensante es conocida. En este sentido, Gassendi y Bourdin cuestionan la posibilidad de este conocimiento, destacando la ambiguedad y oscuridad de las respuestas cartesianas. Se concluye que en las Meditaciones,Descartes enfrenta una brecha insalvable entre la ontología de la sustancia y su conocimiento, loque lo llevará a desarrollar y explicar mejor su teoría en escritos posteriores.

A sala de aula era clara, arejada, ampla e comportava vinte e cinco crianças de 6 anos de idade. Elas moravam num bairro da periferia da cidade, onde estava localizada a escota. Eram, portanto, crianças filhas de famílias de baixa renda. A professora era jovem, entusiasmada, democrática, residia perto da escola, fazendo parte da mesma comunidade das crianças. Ela estava fortemente incorporada pelo trabalho pedagógico fundamentado em Freinet. A classe era dividida em "ateliers", que as crianças chamavam de "caninhos", distribuídos (...) da seguinte maneira: o cantinho da Construção, cujos materiais eram blocos de madeira, caixas de papelão em diversos tamanhos e paus de vassoura coloridos, grandes, médios e pequenos; o das Artes continha tintas, pincéis, giz, giz de cera, lápis de cor, "a caixa de carimbos", papel jornal, roupas usadas de adulto, maquiagem, cola, tesoura e material de sucata; o cantinho da Escrita guardava o quadro-negro, lápis, cadernos de desenho grandes, folhas de papel de computador, papel pardo e papel sulfit; no da Biblioteca estavam os livros de estória e revistas diversas; o do Museu era identificado por objetos curiosos trazidos de casa pelas crianças, tais como pedras consideradas por elas diferentes e bonitas, vidros contendo areia colorida trabalhada artisticamente.

O ensaio teórico-reflexivo tem como objeto de discussão uma reflexão sobre a relação entre a alfabetização de jovens e adultos e o sentido da educação emancipatória a partir dos postulados de Paulo Freire, educador brasileiro que trouxe uma nova visão de educação, caracterizada como revolucionária. Uma análise das políticas públicas de EJA, com destaque para a alfabetização de adultos na década de 1990 até os dias atuais, é apresentada com o objetivo de compreender como a descontinuidade e fragilidade de tais (...) políticas têm sido um entrave para o desenvolvimento de projetos educativos de escolarização inicial e continuada, cúmplices do compromisso da formação e emancipação dos sujeitos. Destaca-se no texto o significado de emancipação em Freire como humanização do oprimido e superação dos seus condicionamentos históricos. Apresenta a educação de jovens e adultos pautada no diálogo e problematização como um ato político, agente de conscientização e potencializadora da emancipação do ser. (shrink)

Haraway understands that the social space is not homogenous, and that the three dimensions that Harding detects: generic symbolism, partner-sexual division of the work and processes of gendered individual identity, they are intercepted in multiple dimensions.

A pergunta pelo ser do homem é a origem da antropologia tanto filosófica quanto pedagógica. Neste horizonte, pode-se resumir a resposta à pergunta dizendo: o ser humano não só é efeito do diálogo, mas humaniza e se humaniza por meio do diálogo. Quando se planeja ambientes orientados a desenvolver as potências anímicas do diálogo em todos, e em cada um dos participantes da cena pedagógica, igualmente se está tanto em meio a uma antropologia pedagógica quanto a uma didática antropológica. Esta (...) foi a tradição que Christoph Wulf, na segunda metade do século XX e no começo do século XXI, sistematizou. Dentro desta corrente de pensamento se enquadra a investigação intitulada Diálogo: condição de formação. Assim, pode-se afirmar que este projeto se baseia na tradição alemã que põe a Bildung no centro, como uma categoria que, ao mesmo tempo, tem uma fundamentação filosófica e alguns efeitos tanto na concepção quanto na ação pedagógica.

Taking literally the concept of emotional truth requires breaking the monopoly on truth of belief-like states. To this end, I look to perceptions for a model of non-propositional states that might be true or false, and to desires for a model of propositional attitudes the norm of which is other than the semantic satisfaction of their propositional object. Those models inspire a conception of generic truth, which can admit of degrees for analogue representations such as emotions; belief-like states, by contrast, (...) are digital representations. I argue that the gravest problem-objectivity-is not insurmountable. /// [Adam Morton] It is accuracy rather than truth itself that is valuable. Emotional truth is a dubious though attractive notion, but emotional accuracy is much easier to make sense of. My approach to accuracy goes via an account of what makes a story accurate. Stories can be accurate but not true, and emotions can be accurate whether or not they are true. The capacity for emotional accuracy, for emotions that fit a person's situation, is an aspect of emotional intelligence, which is as important an aspect of rational human agency as the intelligent formation of beliefs and desires.
