Contractarians aim to derive moral principles from the dictates of instrumental rationality alone. But it is well-known that contractarian moral theories struggle to identify normative principles that are both uniquely rational and morally compelling. Michael Moehler's recent book, *Minimal Morality* seeks to avoid these difficulties by developing a novel "two-level" social contract theory, which restricts the scope of contractarian morality to cases of deep and persistent moral disagreement. Yet Moehler remains ambitious, arguing that a restricted version of Kant's categorical imperative (...) is a uniquely rational principle of conflict resolution. We develop a formal model of Moehler's informal game-theoretic argument, which reconstructs a valid argument for Moehler's conclusion. This model, in turn, enables us to expose how a successful argument for Moehler's contractarian principle rests on assumptions that can only be justified by subtle yet significant departures from the standard conception of rationality. We thus extend our understanding of familiar contractarian difficulties by showing how they arise even if we restrict the scope of contractarian morality to a domain where its application seems both promising and necessary. We show that the problem lies not in contractarians' immodest ambitions but in the modest resources rationality can offer to satisfy them. (shrink)

While psychotherapists are trained to improve their clients’ quality of life, little work has examined the quality of life experienced by psychotherapist trainees themselves. Yet their life satisfactions and stresses would plausibly affect both their ability to learn new skills and conduct psychotherapy. Therefore, in the Society for Psychotherapy Research Interest Section on Psychotherapist Development and Training study, we investigated the patterns of self-reported life quality and their correlates in a multinational sample of 1,214 psychotherapist trainees. A comprehensive questionnaire was (...) used at the outset of trainings to assess trainees’ professional background, current life situation, personal characteristics, family background, and social and national origin. The findings indicated 54.3% of trainees’ lives could be characterized as fortunate or happy, whereas 14.3% could be characterized as clearly distressed or troubled. The strongest correlates of high life stress, a contributor to poor life quality, were economic insecurity, self-protectiveness, and attachment-related anxiety in relationships, and economic or psychological hardship in childhood. In turn, greater wellbeing was most strongly associated with a warm and open interpersonal style, being married, having sufficient economic means, and material and emotional security in childhood. While the results indicate the majority of therapists experience a relatively good quality of life, the findings also suggest potential targets for increasing trainees’ life quality when it may be deficient, such as those on a societal level, training program level, and individual level, in order to promote effective learning and therapy practice.

Resumen El artículo se propone mostrar cómo, en El can de Kant, la filosofía llega a ser cuestionada por la literatura, y qué tipo de operación crítica o deconstructiva esta última posibilita. Muestra en particular que los problemas de la imaginación y del tiempo en Kant están enfocados a partir de la experiencia de la memoria y de la traducción en Borges. Finalmente, se sugiere que, mientras la imaginación posibilita la conformación de objetos, y por ende la posibilidad de tener (...) a un perro, la literatura abre a otras formas de territorialidad, de relaciones y de asunción del cuerpo.This article aims to show how in Kant’s Dog philosophy can be questioned by literature, and what kind of critical or deconstructive operation the later enables. In particular, it shows that the problem of imagination and time in Kant are focused on the experience of memory and translation in Borges. Finally, the article suggests that while imagination enables the conformation of objects, and therefore the possibility of having a dog, the literature opens to other forms of territorialities, of relationships, and of assumption of the body.

This article investigates the claims made in the dedicatory epistle to Girolamo Manfredi’s De homine to have effected an Italian translation of various earlier works. First published in 1474, the De homine is strongly dependent on the pseudo-Aristotelian Problems, for which several translations into Latin were available by Manfredi’s time as well as the highly influential commentary by Pietro d’Abano. Focusing on one particular section of the De homine, on voice, this article offers an analysis of the various sources used (...) and of the extent to which Manfredi is indeed offering a translation or something different. This study concludes that Manfredi closely followed the translation by Bartolomeo da Messina and the commentary by Pietro d’Abano; it finds no clear evidence of his use of the translations by George of Trebizond or Theodore Gaza. Other sources used include especially Rhazes’ Ad Almansorem. (shrink)

Previous research on the interpersonal effects of emotions in negotiation suggested that bargainers obtain higher outcomes expressing anger, when it is not directed against the counterpart as a person and it is perceived as appropriate. Instead, other studies indicated that successful negotiators express positive emotions. To reconcile this inconsistency, we propose that the direction of the effects of emotions depends on their perceived target, that is, whether the negotiators’ emotions are directed toward their opponent’s proposals or toward their own ‘exit (...) option’. An ultimatum game scenario experiment showed that negotiators who express positive emotion rather than negative, in addition to benefits in terms of relationship fortification, received better offers when participants perceived the negotiators’ emotions directed toward their own ‘exit option’. These findings indicate that positive emotions may signal the availability of better ‘exit option’, suggesting that happiness expressions can be strategically used to maximize both material and relational outcomes.

This paper recognizes a specific correspondence between biological evolution and technological development and on this basis tries to set up a semioticapproach to the evolutionary phenomenon of exaptation. To do this, the existence of a historical-structural and pragmatic analogy between organs and tools is shown, which in turn implies on a communicative ground the dissolution of some of their traditional distinctive att ributes. Finally, a philosophical-analytical approach to natural and cultural functions is applied to define three types of exaptations.

The so-called transparency of experience (TE) is the intuition that, in introspecting one’s own experience, one is only aware of certain properties (like colors, shapes, etc.) as features of (apparently) mind-independent objects. TE is quite popular among philosophers of mind and has traditionally been used to motivate Representationalism, i.e., the view that phenomenal character is in some strong way dependent on intentionality. However, more recently, others have appealed to TE to go the opposite way and support the phenomenal intentionality view (...) (PIV), according to which intentionality is in some strong way dependent on phenomenal character. If this line of argument succeeds, then not only TE does not speak in favor of Representationalism, but it actually speaks against it, contrary to the philosophical common-sense of the last two decades. Moreover, the representationalist project of naturalizing phenomenal character turns out to be seriously undermined on the same intuitive grounds that were supposed to make it plausible. In this paper, I reconstruct and discuss the line of argument from TE to PIV and argue that our introspective intuitions (TE) do not push us in the direction of PIV. On the contrary, the line of argument from TE to PIV is (at best) simply too weak to force us to conclude that intentionality depends on phenomenal character in the sense required for PIV to be true.

In this paper we show that axiomatic extensions of H. Wansing’s connexive logic $$\textsf{C}$$ ( $$\textsf{C}^{\perp }$$ ) are algebraizable (in the sense of J.W. Blok and D. Pigozzi) with respect to sub-varieties of $$\textsf{C}$$ ( $$\textsf{C}^{\perp }$$ )-algebras. We develop the structure theory of $$\textsf{C}$$ ( $$\textsf{C}^{\perp }$$ )-algebras, and we prove their representability in terms of twist-like constructions over implicative lattices (Heyting algebras). As a consequence, we further clarify the relationship between the aforementioned classes. Finally, taking advantage of (...) the above machinery, we provide some preliminary remarks on the lattice of axiomatic extensions of $$\textsf{C}$$ ( $$\textsf{C}^{\perp }$$ ) as well as on some properties of their equivalent algebraic semantics.

Although brain size and the concept of intelligence have been extensively used in comparative neuroscience to study cognition and its evolution, such coarse-grained traits may not be informative enough about important aspects of neurocognitive systems. By taking into account the different evolutionary trajectories and the selection pressures on neurophysiology across species, Logan and colleagues suggest that the cognitive abilities of an organism should be investigated by considering the fine-grained and species-specific phenotypic traits that characterize it. In such a way, we (...) would avoid adopting human-oriented, coarse-grained traits, typical of the standard approach in cognitive neuroscience. We argue that this standard approach can fail in some cases, but can, however, work in others, by discussing two major topics in contemporary neuroscience as examples: general intelligence and brain asymmetries.

During the first wave of the COVID-19 pandemic in Italy, practitioners had to make tragic decisions regarding the allocation of scarce resources in the ICU. The Italian debate has paid a lot of attention to identifying the specific regulatory criteria for the allocation of resources in the ICU; in this paper, however, we argue that deciding such criteria is not enough for the implementation of fair and transparent allocative decisions. In this respect, we discuss three ethical issues: (a) in the (...) Italian context, the treating physician, rather than a separate committee, was generally the one responsible for the allocation decision; (b) although many allocative guidelines have supported moral equivalence between withholding and withdrawing treatments, some health professionals have continued to consider it a morally problematic aspect; and (c) the health workers who have had to make the aforementioned decisions or even only worked in ICU during the pandemic often experienced moral distress. We conclude by arguing that, even if these problems are not directly related to the above-mentioned issues of distributive justice, they can nevertheless directly affect the quality and ethics of the implementation of allocative criteria, regardless of those chosen.

Baker claims to provide an example of mathematical explanation of an empirical phenomenon which leads to ontological commitment to mathematical objects. This is meant to show that the positing of mathematical entities is necessary for satisfactory scientific explanations and thus that the application of mathematics to science can be used, at least in some cases, to support mathematical realism. In this paper I show that the example of explanation Baker considers can actually be given without postulating mathematical objects and thus (...) cannot be used by the mathematical realist. I also show that, despite this, mathematics keeps playing an important methodological role in the explanation and does not reduce to a merely computational or descriptive framework. (shrink)

Lo studio sonda l’incidenza della Völkerpsychologie di Lazarus e Steinthal nei primi testi filosofici di Croce . A partire da quest’angolo prospettico propone un’analisi del complesso atteggiamento del filosofo verso i plessi tematici della Prelezione labrioliana prevalentemente ispirati dalla psicologia dei popoli. Croce non solo interpreta diversamente da Labriola la Völkerpsychologie, rigettandola in quanto illegittimo tentativo di fondazione psicologica degli studi storici maturato nel clima positivistico della seconda metà dell’Ottocento, ma respinge anche il piano generale e le linee strutturanti la (...) filosofia della storia di Labriola, in cui la psicologia dei popoli perde la paradossalità della ricerca di leggi del corso storico per diventare un’analisi delle forme di categorizzazione del fatto storico. Da questo confronto emerge, infine, il compito di classificazione trascendentale assegnato da Croce, nella sua produzione giovanile, alla filosofia. (shrink)

Some philosophers have argued that a standard of correctness is constitutive of the concept or the essence of belief. By this claim they mean, roughly, that a mental state is a belief partially in virtue of being correct if and only if its content is true. In this paper I provide a new argument in support of the constitutivity of the correctness standard for belief. I first argue that the standard expresses a conceptual necessity. Then I argue that, since conceptual (...) necessities are such in virtue of some concept, the standard must also be necessary in virtue of some concept. Finally, I provide an argument by exclusion to the effect that the standard is necessary in virtue of the concept of belief. (shrink)

The article is aimed at pointing out the correctness of the basic assumptions of Maurizio Ferraris’ documental theory of social reality, illustrating the results of a case study research. The theoretical analysis leads to an argument that shows that only the reference to the role of writing (and to a broad and diversified conception of Documentality) makes it possible to clarify the phenomenon of social and historical iteration of intellectual heritage. This latter represents an intangible heritage which is neither part (...) of the external perceivable world, nor of a conjectural platonic reality, since – though possessing abstract essence – it stems from a specific point in time.

Institutions are committed to a constant work aimed at classifying cultural heritages, in order to preserve selected objects from decay or disappearing. In this domain of policy, a significant role is played by architecture and by the preservation of the architectural heritage of cities. How is it possible, however, to determine the value in the field of architectural heritages? What are the criteria for evaluation and the degree of objectivity these classifications are based upon? Is architectural worth immanent to objects (...) or does it reside outside them? These are fundamental questions for the science of preservation and the legislation on cultural heritages. By closely examining a controversial case occurred in the European Union, e.g. England, the paper tackles analytically some of these issues, and it exploits also concepts borrowed from social ontology and ontology of art.

In the debate about Michael Oakeshott’s philosophy there is very little agreement on the theoretical and historical meaning of his skepticism. Starting from the assumption that skepticism is not a fixed theory but a tradition of ideas, this article draws on both published texts and archival materials to contend that Oakeshott developed his thought by confronting himself with, and even merging, different strands of skepticism: the ancient, the modern, as represented by Hobbes and Montaigne, and the idealist, as conceived by (...) F. H. Bradley. The article firstly shows Oakeshott’s awareness of ancient skepticism, even though its impact on his thought is contested and controversial. With regard to modern skepticism, it looks at how Oakeshott defines Hobbes’s skepticism in his “Introduction to Leviathan.” It also examines the relevance of Montaigne to Oakeshott’s image of conversation, his idea of human agency and conception of politics. Finally, the article illustrates the influence of Bradley’s skepticism on Oakeshott’s conception of philosophy and reveals the consistency between Oakeshott’s skepticism and idealism. What emerges is a complex picture, in which Oakeshott’s skepticism is a constellation of elements taken from a variety of sources. (shrink)

We initiate a geometric stability study of groups of the form G/G00, where G is a 1-dimensional definably compact, definably connected, definable group in a real closed field M. We consider an enriched structure M′ with a predicate for G00 and check 1-basedness or non-1-basedness for G/G00, where G is an additive truncation of M, a multiplicative truncation of M, SO2(M) or one of its truncations; such groups G/G00 are now interpretable in M′. We prove that the only 1-based groups (...) are those where G is a sufficiently “big” multiplicative truncation, and we relate the results obtained to valuation theory. In the last section we extend our results to ind-hyperdefinable groups constructed from those above. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:diacritics 30.2 (2000) 113-126 [Access article in PDF] Dissenting Words:A Conversation with Jacques Rancière 1 Davide Panagia:In your writings you highlight the political efficacy of words. In The Names of History, for instance, this emphasis is discussed most vividly in terms of what you refer to as an "excess of words" that marks the rise of democratic movements in the seventeenth century. Similarly, in On The Shores of (...) Politics, you begin your discussion with an excursus on the end of politics as the end of the promise. Finally, in Dis-agreement you speak of "the part of those who have no-part" as voicing a "wrong" for the sake of equality.In each of these instances, however, your treatment of words (and language more generally) is very different from those thinkers of the "linguistic turn" in political philosophy who expound on an ethics of deliberation as the first virtue of modern democracies. For that matter, your approach is quite different from those thinkers who focus on the aporias of language as such.Could you discuss this thematic of the proliferation of words in your thinking about democratic politics?Would it be fair to characterize your research on and exposition of democratic thinking as a "poetics of politics"?Rancière's Reply:In order to address your question adequately, it would be wise to enlarge the sense of "linguistic turn" you invoke. In its most generally accepted sense, the linguistic turn in philosophy consists in ascribing to linguistic processes certain phenomena and specifiable modes of relating objects attributed, in a previous instance, either to factual processes or lines of thought. This approach is not limited to the two figures you invoke in your question. The linguistic turn also has two stages of development that, from my experience, have been more noticeable in France than in the United States. The first phase, then, emerged with Lévi-Strauss and his structural approach to social relations founded on a linguistic model of relationality, subsequently reprised in Lacan's psychoanalytic notion that "the unconscious is structured like a language" that, in its turn, conjoins the energetic mental processes Freud discusses to linguistic practices. The primacy of "the linguistic" thus granted language all the properties of the Freudian unconscious [End Page 113] along with those of a Marxist notion of infrastructure. The Saussurian opposition between langue and parole provided a privileged status to a linguistic model whose role was that of a general law that unconsciously structures the behavior of individuals and societies. It is on the basis of these parameters that the structuralist moment of the linguistic turn was constituted. At one and the same time, the analysis of speech acts became first and foremost a "symptomatic" analysis of those procedures of misrecognition that linguistically structured both the behavior of individuals and social relations. When we "read" Le Capital with Althusser, the interpretive and methodological schema for linguistic phenomena operated like a kind of "policing of the enunciated": that is, a search for those unsuccessful (i.e., inadequate) modes of expression that exemplify such symptomatic procedures of misrecognition.The second phase of the linguistic turn constituted itself more ambiguously. For those who shared intellectual experiences similar to my own, this version involved a critique of the langue/infrastructure model; that is, a further and more favorable consideration of the value of the political and the linguistic games therein that, according to the Althusserian/Marxist model (and, indeed, with structuralism more generally), were to be treated as ideological artifacts. In a very real sense, it all began with the May '68 assertion that "we are all German Jews"--an entirely ideological statement, the validity of which, if analyzed at the level of its content, one finds to rest entirely on the capacity to overturn the political relationship between the order of designations and that of events by emphasizing the gap that separates subject and predicate. From there, an entire field of understanding speech acts as political gestures opened up: a field that reconfigured the division between words and things while rearranging the distinction between legitimate...

Inspired by some logical considerations, the paper proposes a novel perspective on the use of two-players zero-sum games in abstract argumentation. The paper first introduces a second-order modal logic, within which all main Dung-style semantics are shown to be formalizable, and then studies the model checking game of this logic. The model checking game is then used to provide a systematic game theoretic proof procedure to test membership with respect to all those semantics formalizable in the logic. The paper discusses (...) this idea in detail and illustrates it by providing a game for the so-called skeptical preferred and skeptical semi-stable semantics. (shrink)

This paper contributes to the growing discussion about how to mitigate pharmaceutical pollution, which is a threat to human, animal, and environmental health as well as a potential driver of antimicrobial resistance. It identifies market approval of pharmaceuticals as one of the most powerful ways to shape producer behavior and highlights that applying this tool raises ethical issues given that it might impact patients’ access to medicines. The paper identifies seven different policy options that progressively give environmental considerations increased priority (...) in the approval process, identifies ethically relevant interests affected by such policies, and makes explicit tensions and necessary tradeoffs between these interests. While arguing that the current European regulation gives insufficient weight to environmental considerations, the paper highlights concerns with the strongest policy options, on the grounds that these may very well endanger patients’ access to effective medication.

Individuals sit on the board of directors and set organizational goals, individuals make the product, push new marketing campaigns, make tough decisions, create new products, and so on. What is the role of social responsibility (SR) in their thinking? Do individuals need to behave responsibly to live in a social environment? Could this be grounded in their cognition? Furthermore, is there room for SR in our cognitive processes? And then, how can this analysis help studies on socially responsible business? The (...) article presents how the distributed cognition approach provides a viable explanation for SR in human thinking. The exploitation of external – both social and nonsocial – resources shapes cognitive processes such that the idea of the “isolated brain” is definitely abandoned. Our social cognition uses responsibility as a support mechanism that sustains or discharges distributive processes. The article uses the notion of docility to keep cognition and social behavior together. The conclusion is that SR is (1) a mechanism that allows individuals to maintain cognitive advantages and (2) it emerges when the same social channel is exploited for extended periods of time.

Peano's axiomatizations of geometry are abstract and non-intuitive in character, whereas Peano stresses his appeal to concrete spatial intuition in the choice of the axioms. This poses the problem of understanding the interrelationship between abstraction and intuition in his geometrical works. In this article I argue that axiomatization is, for Peano, a methodology to restructure geometry and isolate its organizing principles. The restructuring produces a more abstract presentation of geometry, which does not contradict its intuitive content but only puts it (...) into a particular form. (shrink)

Believing in free will may arise from a biological need for control. People induced to disbelieve in free will show impulsive and antisocial tendencies, suggesting a reduction of the willingness to exert self-control. We investigated whether undermining free will affects two aspects of self-control: intentional inhibition and perceived self-control. We exposed participants either to anti-free will or to neutral messages. The two groups then performed a task that required self-control to inhibit a prepotent response. No-free will participants showed less intentional (...) inhibitions than controls, suggesting a reduction of self-control. We assessed perceived self-control by asking participants whether the response resulted from a deliberate intention or from an impulsive reaction. Perceived self-control was lower in the no-free will group than in control group. Our findings show that undermining free will can degrade self-control and provide insights into how disbelieving in free will leads to antisocial tendencies. (shrink)

This paper aims to perform a multi-level analysis of the Irish public discourse on Covid-19. Despite widespread agreement that Ireland’s response was rapid and effective, the country’s journey through the pandemic has been no easy ride. In order to contain the virus, the Government’s emergency legislation imposed draconian measures including the detention and isolation of people deemed to be even “a potential source of infection” and a significant extension of An Garda Síochána’s power of arrest. In April 2020, journalists John (...) Waters and Gemma O’Doherty initiated judicial review proceedings before the High Court to challenge such legislation, which they defined as unconstitutional, “disproportionate” and based on “fraudulent science”. The proceedings attracted widespread media coverage in what soon became a debate on the legitimacy of emergency legislation and the notion of ‘fake news’ itself. After a brief survey of the legislative background to Ireland’s Covid response, the argumentative strategy is analysed through which the High Court eventually dismissed Mr Waters and Ms O’Doherty’s challenge. Focusing on the process of justification of the judicial decision, the paper provides a descriptive account of the argument structure of the Court’s decision. This sheds light on the pattern of multiple argumentation through which the Court interpreted relevant norms in the Constitution and at once re-established the primacy of “facts” informing political decision-making at a time of national emergency.

I introduce and defend a view about knowledge that I call Moderate Skeptical Invariantism. According to this view, a subject knows p only if she is practically certain that p, where practical certainty is defined as the confidence a rational subject would have to have for her to believe that p and act on p no matter the stakes.

This paper examines the ethological notion of ritualization from the perspective of zoosemiotic studies. Instead of moving within the horizon of traditional semiotic approaches to this phenomenon, my aim is to propose an alternative attempt of modelling based on the linguistic and semiotic concepts of context and contextuality. At the same time, the paper identifies ritualization as a case of exaptation, suggesting the extension of the context-based model within evolutionary biology and the agenda of its semiotic description, namely biosemiotics. At (...) lenght, a potential application of the model is suggested with respect to human ritualization, essentially as a means to prevent inadequate adaptationist considerations. (shrink)

The concept of authority crosses many social sciences, but there is a lack of common taxonomy and definitions on this topic. The aims of this review are: to define the basic characteristics of the authority relationship, reaching a definition suitable for the different domains of social psychology and social sciences; to bridge the gap between individual and societal levels of explanation concerning the authority relationship, by proposing an interpretation within the framework of social representations. The authority relationship can be conceived (...) as a negotiation of meanings and it is closely linked to shared value orientation and the attribution of meanings negotiated within a society. We assume that the authority relationship is socially constructed and represents both a shared representation of society and a normative principle of social life. A multidisciplinary approach is adopted, crossing definitions and studies provided in sociology, political science, law and social psychology. (shrink)

In _The Poetics of Political Thinking_ Davide Panagia focuses on the role that aesthetic sensibilities play in theorists’ evaluations of political arguments. Examining works by thinkers from Thomas Hobbes to Jacques Rancière, Panagia shows how each one invokes aesthetic concepts and devices, such as metaphor, mimesis, imagination, beauty, and the sublime. He argues that it is important to recognize and acknowledge these poetic forms of representation because they provide evaluative standards that theorists use in appraising the value of ideas—ideas (...) about justice, politics, and democratic life. An investigation into the intertwined histories of aesthetic and political accounts of representation—such as Panagia presents here—sheds light on how modes of poetic thinking delimit the questions of unity and diversity that continue to animate contemporary political theory. Panagia not only illuminates the structure of much contemporary political theory but also shows why understanding the poetics of political thinking is vital to contemporary society. Drawing on Gilles Deleuze’s critique of negation and his privileging of paradox as the source of political thought, Panagia suggests that a non-teleological concept of difference might generate insight into pressing questions about foreignness and citizenship. Turning to the liberal/poststructural debate that dominates contemporary political theory, he compares John Rawls’s concept of justice to Rancière’s ideas about political disagreement in order to demonstrate how, despite their differences, both thinkers comprehend aesthetic and moral reasoning as part and parcel of political writing. Considering the writings of William Hazlitt and Jürgen Habermas, he describes how the essay has become the exemplary genre of what is considered rational political argument. _The Poetics of Political Thinking_ is a compelling reappraisal of the role of representation within political thought.

Convolutional neural networks, which automatically learn features from raw data to approximate functions, are being increasingly applied to the end-to-end analysis of electroencephalographic signals, especially for decoding brain states in brain-computer interfaces. Nevertheless, CNNs introduce a large number of trainable parameters, may require long training times, and lack in interpretability of learned features. The aim of this study is to propose a CNN design for P300 decoding with emphasis on its lightweight design while guaranteeing high performance, on the effects of (...) different training strategies, and on the use of post-hoc techniques to explain network decisions. The proposed design, named MS-EEGNet, learned temporal features in two different timescales in an efficient and optimized way, and was validated on three P300 datasets. The CNN was trained using different strategies and was compared with several state-of-the-art algorithms. Furthermore, variants of the baseline MS-EEGNet were analyzed to evaluate the impact of different hyper-parameters on performance. Lastly, saliency maps were used to derive representations of the relevant spatio-temporal features that drove CNN decisions. MS-EEGNet was the lightest CNN compared with the tested SOA CNNs, despite its multiple timescales, and significantly outperformed the SOA algorithms. Post-hoc hyper-parameter analysis confirmed the benefits of the innovative aspects of MS-EEGNet. Furthermore, MS-EEGNet did benefit from transfer learning, especially using a low number of training examples, suggesting that the proposed approach could be used in BCIs to accurately decode the P300 event while reducing calibration times. Representations derived from the saliency maps matched the P300 spatio-temporal distribution, further validating the proposed decoding approach. This study, by specifically addressing the aspects of lightweight design, transfer learning, and interpretability, can contribute to advance the development of deep learning algorithms for P300-based BCIs.

Background: In the present study, we aimed to better investigate attention system profile of Parkinson's disease-Mild Cognitive Impairment patients and to determine if specific attentional deficits are associated with 123I-FP-CIT SPECT.Methods: A total of 44 de novo drug-naïve PD patients [ with normal cognition and 17 with MCI ], 23 MCI patients and 23 individuals with subjective cognitive impairment were recruited at the Clinical Neurology Unit of Santa Chiara hospital. They were assessed by a wide neuropsychological battery, including Visual Search (...) Test measuring selective attention. Performances among groups were compared by non-parametric tests. Further, Spearman's rank correlations were performed to explore the association between neuropsychological variables and 123I-FP-CIT SPECT data in PD subgroup.Results: PD-MCI patients performed worse on VST than patients with PD-NC, patients with MCI and individuals with SCI. The performance of PD-MCI patients on VST significantly correlated with caudate nucleus 123I-FP-CIT SPECT uptake, whereas a negative correlation between such test and 123I-FP-CIT SPECT uptake in the left putamen was found in PD-NC patients.Conclusions: We suggest that selective attention deficit might be a trigger of cognitive decay in de novo PD-MCI patients. The VST should be routinely used to detect attentional deficits in hospital clinical practice, in the light of its closely association with dopamine depletion of basal ganglia in mildly impaired PD patients.
