REM sleep behaviour disorder is a REM sleep-related parasomnia which may be considered a “dissociated state of wakefulness and sleep”, given that conflicting elements of REM sleep and of wakefulness coexist during the episodes, leading to motor and behavioural manifestations reminiscent of an enacted dream. RBD has been reported in association with α-synucleinopathies: around a third of patients with Parkinson’s disease have full-blown RBD.Recent data indicate that PD patients with RBD are more prone to hallucinations than PD patients without this (...) parasomnia. However it is still not clear why RBD in PD is associated with an increased prevalence of VHs.Data exist which suggest that visual hallucinations in PD may be the result of untimely intrusions of REM visual imagery into wakefulness. RBD, which is characterised by a REM sleep dissociation pattern, might be a condition that particularly favours such intrusions. However, other hypotheses may be advanced. In fact, deficits in attentional, executive, visuoperceptual and visuospatial abilities have been documented in RBD and found to occur far more frequently in PD with RBD than in PD without RBD. Neuropsychological deficits involving visual perception and attentional processes are thought to play an important role in the pathophysiology of VHs. On this basis, RBD in PD could be viewed as a contributory risk factor for VHs. (shrink)

We-thinking theories allow groups to deliberate as agents. They have been introduced into the economic domain for both theoretical and empirical reasons. Among the few scholars who have proposed formal approaches to illustrate how we-thinking arises, Bacharach offers one of the most developed theories from the game theoretic point of view. He presents a number of intuitions, not always mutually consistent and not fully developed. In this article, I propose a way to complete Bacharach’s theory, generalizing the interdependence hypothesis and (...) building on his intuition about vacillation. It is a simple model of vacillation between the I and we-modes of reasoning, as a way in which we-thinking can come to mind in the face of a decision problem. The vacillation model makes we-reasoning more easily usable in game theory. (shrink)

It is a common opinion that chance events cannot be understood in causal terms. Conversely, according to a causal view of chance, intersections between independent causal chains originate accidental events, called “coincidences”. Firstly, this book explores this causal conception of chance and tries to shed new light on it. Such a view has been defended by authors like Antoine Augustine Cournot and Jacques Monod. Second, a relevant alternative is provided by those accounts that, instead of acknowledging an intersection among causal (...) lines, claim to track coincidences back to some common cause. Third, starting from Herbert Hart and Anthony Honoré’s view of coincidences (Causation in the Law. Clarendon Press, Oxford, 1959). This book provides a more detailed account of coincidences, according to which coincidental events are hybrids constituted by ontic (physical) components, which is the intersection between independent causal chains, plus epistemic aspects, including but not limited to, access to information, expectations, relevance, significance, desires, which in turn are psychological aspects. -/- The main target of the present work is to show that the epistemic aspects of coincidences are, together with the independence between the intersecting causal chains, a constitutive part of coincidental phenomena. This book aims to introduce and discuss recent work in psychology concerning one’s judgment about coincidences; this data offers further materials and reasons to reflect upon our understanding of coincidences and to refine our hybrid conception.

The exponential rise in transgender self-identification invites consideration of what constitutes an ethical response to transgender individuals’ claims about how best to promote their well-being. In this paper, we argue that ‘accepting’ a claim to medical transitioning in order to promote well-being would be in the person’s best interests iff at the point of request the individual is correct in their self-diagnosis as transgender (i.e., the distress felt to reside in the body does not result from another psychological and/or societal (...) problem) such that the medical interventions they are seeking will help them to realise their preferences. If we cannot assume this—and we suggest that we have reasonable grounds to question an unqualified acceptance in some cases—then ‘acceptance’ potentially works against best interests. We propose a distinction between ‘acceptance’ and respectful, in-depth exploration of an individual’s claims about what promotes their well-being. We discuss the ethical relevance of the unconscious mind to considerations of autonomy and consent in working with transgender individuals. An inquisitive stance, we suggest, supports autonomous choice about how to realise an embodied form that sustains well-being by allowing the individual to consider both conscious and unconscious factors shaping wishes and values, hence choices.

In this chapter I show that idealizing assumptions can obscure conversational dynamics because they neglect power differentials that are crucial enablers of the successful performance of some speech acts (see, Sbisà, 2020). I examine how silencing is promoted by conversational norms that would defeasibly entitle linguistic agents to presume that silence indicates acceptance. I focus on Goldberg’s (2020) discussion of these phenomena. Goldberg argues in support of a norm of no silent rejections claiming that silencing is partly the result of (...) the misapplication of this norm. He further defends the view that the norm itself is part of the solution to the problem of silencing. In the chapter I argue that Goldberg is mistaken on these points. Instead, drawing inspiration from Sbisà (2020), I argue that norms of no silent rejection are temporarily enacted by means of speech acts that function as exercitive assertions. (shrink)

Logical metonymy resolution (begin a book begin reading a book or begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post-lexical access to world knowledge. We propose that recent work within the words-as-cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self-paced (...) reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause-final target verb (Der Konditor begann die Glasur Der Konditor begann, die Glasur aufzutragen/The baker began the icing The baker began spreading the icing). Longer reading times at the target verb position in a high-typicality condition (baker + icing spread ) compared to a low-typicality (but still plausible) condition (child + icing spread) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high-typicality or a low-typicality metonymic sentence (Der Konditor begann die Glasur AUFTRAGEN/The baker began the icing SPREAD), we obtain an analogous effect of typicality at 100 ms interstimulus interval.

Combining philosophy and literature, this book considers distraction not as an imperfection, but as a mental state with political and aesthetic potential.

After more than three centuries, Molyneux's question continues to challenge our understanding of cognition and perceptual systems. Locke, the original recipient of the question, approached it as a theoretical exercise relevant to long-standing philosophical issues, such as nativism, the possibility of common sensibles, and the empiricism-rationalism debate. However, philosophers were quick to adopt the experimentalist's stance as soon as they became aware of recoveries from congenital blindness through ophtalmic surgery. Such recoveries were widely reported to support empiricist positions, suggesting that (...) the question had found its empirical answer. Contrary to this common view, we argue that studies of patients recovering from early blindness through surgery cannot provide an answer. In fact, because of the very nature of such ophtalmological interventions it is impossible to test the question in the empirical conditions outlined by Molyneux. Thus we propose that Molyneux's question be treated as an early thought experiment of a specific kind. Although thought experiments of this kind cannot be turned into actual experimental conditions, they provide a conceptual restructuring of theories. Such restructuring in turn leads to new predictions that can then be tested by normal experiments. In accord with this interpretation, we show that Molyneux's question can be analyzed into a hierarchy of specific questions about vision in its phenomenal and sensory-motor components. Some of these questions do lead to actual experimental conditions that could be studied empirically. (shrink)

Samson Abramsky’s wide-ranging contributions to logical and structural aspects of Computer Science have had a major influence on the field. This book is a rich collection of papers, inspired by and extending Abramsky’s work. It contains both survey material and new results, organised around six major themes: domains and duality, game semantics, contextuality and quantum computation, comonads and descriptive complexity, categorical and logical semantics, and probabilistic computation. These relate to different stages and aspects of Abramsky’s work, reflecting its exceptionally broad (...) scope and his ability to illuminate and unify diverse topics. Chapters in the volume include a review of his entire body of work, spanning from philosophical aspects to logic, programming language theory, quantum theory, economics and psychology, and relating it to a theory of unification of sciences using dual adjunctions. The section on game semantics shows how Abramsky’s work has led to a powerful new paradigm for the semantics of computation. The work on contextuality and categorical quantum mechanics has been highly influential, and provides the foundation for increasingly widely used methods in quantum computing. The work on comonads and descriptive complexity is building bridges between currently disjoint research areas in computer science, relating Structure to Power. The volume also includes a scientific autobiography, and an overview of the contributions. The outstanding set of contributors to this volume, including both senior and early career academics, serve as testament to Samson Abramsky’s enduring influence. It will provide an invaluable and unique resource for both students and established researchers. (shrink)

En los manuscritos de la novela Trento, de Leónidas Lamborghini, los comentarios sobre el espectador evidencian la fuerza que adquiere la dimensión teatral y narrativa en toda su obra, no solo en cuanto a técnicas tomadas prestadas de lo dramático sino sobre todo en cuanto a las consideraciones con respecto a los géneros y sus bordes. La organización del Fondo Lamborghini ha permitido un exhaustivo análisis de los aspectos que comparten sus obras narrativas con los “textos dramáticos” de Trentoen cuanto (...) a didascalias o préstamos de formatos escénicosy, sobre todo, de la concepción de espectador/lector presente en algunas de sus obras. Una edición genética basada en la búsqueda de los itinerarios que van y vienen a través de las fronteras genéricas entre novela y teatro presenta aspectos de interés para pensar no solo esta particular obra de Leónidas Lamborghini sino también todo su trabajo poético y narrativo, dado que los procedimientos y trabajos formales de reescritura son persistentes a lo largo de su creación.

We show unintended consequences of quota regulations to get women on boards. Board members may have different characteristics, and even among women, there are variations. We assume that the characteristics of the board members have an influence on their contributions to boards, to businesses as well as to society. In this paper, we argue that different types of societal pressure to get women on boards have an influence on the social capital characteristics of the women getting multiple board memberships. The (...) paper is drawing on institutional theory and social capital theory, and we distinguish between mimetic, normative, and coercive types of pressure. Through a cluster analysis of 58 Italian “golden skirts”, we show that different types of societal pressure may lead to differences in social capital characteristics. The study has implications for the ongoing international debate about women and diversity on boards, and we propose developing a pressure theory for getting women on boards. (shrink)

It is a familiar experience to perceive a material object as maintaining a stable shape even though it projects differently shaped images on our retina as we move with respect to it, or as maintaining a stable color throughout changes in the way the object is illuminated. We also perceive sounds as maintaining constant timbre and loudness when the context and the spatial relations between us and the sound source change over time. But where does this perceptual invariance ‘come from’? (...) What is it about our perceptual systems that makes them able to ‘transform’ incoming unstable and fluctuating sensory inputs into generally stable and coherent conscious experiences? And what exactly do we experience as invariant in cases like those described above? There are two main approaches to the Problem of Perceptual Invariance: the Local-Inferential approach and the Global-Structural approach. Although both approaches include an account of the sub-personal perceptual mechanisms ‘stabilizing’ variant and invariant components in incoming sensory stimulation and a proposal regarding the phenomenology of perceptual invariance, in this paper I argue that the latter provides a better solution to the problem overall.

Word learning is basic to foreign language acquisition, however time consuming and not always successful. Empirical studies have shown that traditional (visual) word learning can be enhanced by gestures. The gesture benefit has been attributed to depth of encoding. Gestures can lead to depth of encoding because they trigger semantic processing and sensorimotor enrichment of the novel word. However, the neural underpinning of depth of encoding is still unclear. Here, we combined an fMRI and a behavioral study to investigate word (...) encoding online. In the scanner, participants encoded 30 novel words of an artificial language created for experimental purposes and their translation into the subjects’ native language. Participants encoded the words three times visually, audiovisually, and by additionally observing semantically related gestures performed by an actress. Hemodynamic activity during word encoding revealed the recruitment of cortical areas involved in stimulus processing. In this study, depth of encoding can be spelt out in terms of sensorimotor brain networks that grow larger the more sensory modalities are linked to the novel word. Word retention outside the scanner documented a positive effect of gestures in a free recall test in the short-term. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Why Is the Gorgias so Bitter?1Alessandra FussiMihi in oratoribus irridendis ipse esse orator summus videbatur.-Cicero, De Oratore 1.471. The hand of an apprentice?Commentators have often responded with uneasiness to Plato's Gorgias. E. R. Dodds speaks of the "disillusioned bitterness" of the criticisms leveled against Athenian politics and politicians and of the tragic tone of the dialogue's last part, which culminates in a prediction of Socrates' condemnation (1959, 19). F. (...) M. Cornford observes that the discussion between Socrates and Callicles "is marked by a bitterness of tone rarely found elsewhere in the dialogues" (1945, 21). A. E. Taylor is more explicitly irritated: "Personally-he writes-I cannot help feeling that, with all its moral splendor, the dialogue is too long: it 'drags.' The Plato of the Protagoras or Republic, as I feel, would have known how to secure the same effect with less expenditure of words; there is a diffuseness about our dialogue which betrays the hand of a prentice, though the prentice in this case is Plato" (1960, 103). Many readers of the Gorgias have a similar emotional response, yet the feeling that this is a bitter dialogue is never analyzed, accounted for, or adequately justified.While assessing various hypotheses on the date of composition of the Gorgias, Dodds speculates that its "disillusioned bitterness" may suggest that Plato wrote the dialogue right after Socrates' death and under the impact of the event. The Gorgias is so bitter, the reasoning goes, because Plato was enraged with the Athenians when he wrote it. Dodds goes on to discard the hypothesis of such an early date of composition, but he does not revise his view that this is indeed a bitter dialogue. Why, then, does the [End Page 39] Gorgias sound so bitter? Instead of relying on external factors, I suggest it would be more profitable to turn to the dialogue itself for an answer. After all, the impression of bitterness is a function of the emotional impact that the dialogue has on its readers. A well-constructed chain of arguments can hardly sound bitter. The Gorgias contains many arguments, but its emotional impact must lie elsewhere. So where?In the dialogue, Socrates is involved in three discussions of increasing length and complexity with interlocutors who, in one way or another, defend the power of rhetoric and the superiority of political life over philosophical life. The discussions cannot, however, be characterized as mere exercises in abstract reasoning, or urbane conversations on different views of the good life; the Gorgias is a "fighting dialogue," as indicates its opening sally, "to war and battle" (447a1).2 As the saying goes, these are fighting words, since Callicles is basically accusing Socrates of being a coward.Even if we abstract from the themes evoked in the Gorgias, it is difficult to ignore the peculiarity of its dramatic movement. First, we are plunged in medias res, with no clear indication as to the time and place of the dialogue's unfolding. We then proceed through a tour de force of conversations that begin, are immediately interrupted, start again, and continue through refutations, repeated interruptions, fits of anger, and bad temper. If we expected Socrates to win against his nonphilosophical interlocutors, we are sorely disappointed. The further the conversations proceed, the more they are infiltrated by anger and misunderstanding, and the more we come to feel that, though Socrates' interlocutors may well be silenced, they will remain unpersuaded. Indeed, toward the end of the dialogue, Callicles simply refuses to respond to Socrates, who is finally reduced to performing a monologue. The dialogue ends with a myth addressed to Callicles in the stated conviction that the young man will dismiss it as an old wives' tale (527a5-b3). The invocation of Callicles' name, which concludes the dialogue, is significantly and poignantly left hanging.Besides the points just mentioned, I think that several aspects of the dramatic setting contribute significantly to the dialogue's peculiar emotional impact on its readers. I will try to show this, first, by considering eight dramatic devices Plato uses in the Gorgias and, second, by contrasting these devices with their counterparts in the Protagoras. The two dialogues... (shrink)

Notini et al 1 offer a timely addition in the wake of a significant increase in young people identifying as transgender and gender diverse. The authors focus specifically on the case of 18-year-old Phoenix’s request for ongoing puberty suppression to affirm a non-binary gender identity. A central issue raised by Phoenix’s predicament, and that I suggest we can extend to ethical consideration of requests for other types of medical intervention by binary and non-binary TGD individuals, is whether we should ‘affirm’ (...) the claims made by TGD young people about what promotes their well-being. As a clinician working with TGD young people who have undergone a range of medical interventions to align their bodies with their gender identity, my starting presumption is that it is important to respect what people think will help them: there are some TGD young people for whom, all things considered, medical interventions to affirm gender identity promote their well-being. Well-being has become an important conceptual currency in ethical debates and lies at the core of the authors’ analysis of Phoenix’s case. While the authors do not ground their argument in favour of OPS in a specific theory of well-being, welfarist considerations 2 appear to underpin …. (shrink)
