We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

The COVID-19 crisis has served not just to instil fear in the populace but to highlight the importance of fear as a motivating dynamic in politics. The gradual emergence of political-philosophical approaches calling for concern for ‘positive’ emotions may have made sense under non-pandemic conditions. Now, however, describing fear in the face of a deadly pandemic as ‘irrational’ or born of ‘ignorance’ seems ‘irrational’ and ‘ignorant’. In this article, we draw upon the work of John Gray and behavioural science to (...) present a defence of fear. We show how the pandemic has highlighted deficits in the work of four thinkers highly critical of fear: Martha Nussbaum, Zygmunt Bauman, Hannah Arendt and Sara Ahmed. We argue that, if such approaches are to be of value in anything other than optimal conditions, then they have to acknowledge the fundamental role of fear in helping human beings to pursue fundamental interests.

Empirical evidence from dialogue, both corpus and experimental, highlights the importance of interaction in language use – and this raises some questions for Christiansen & Chater's proposals. We endorse C&C's call for an integrated framework but argue that their emphasis on local, individual production and comprehension makes it difficult to accommodate the ubiquitous, interactive, and defeasible processes of clarification and repair in conversation.

With over 2 billion people lacking medicines for treatable diseases and 14 million people dying annually from infectious disease, there is undeniable need for increased access to medicines. There has been an increasing trend to benchmark the pharmaceutical industry on their corporate social responsibility (CSR) performance in access to medicines. Benchmarking creates a competitive inter-business environment and acts as incentive for improving CSR. This article investigates the corporate feedback discourses pharmaceutical companies make in response to criticisms from benchmarking reports. It (...) determines whether these responses are part of a healthy process in increasing access to medicines or a barrier to improvement. A qualitative analysis on the feedback the industry provided was performed, and the responses seen in these statements were grouped by analysing the language used, the ideas portrayed and attitudes of the companies. Increasing transparency through benchmarking is a powerful tool which reveals the industry's shortfalls to the public, affects the decisions of socially responsible investors, and is a risk to their financial bottom line. This article demonstrates the importance of benchmarking and transparency in creating inter-business competition and the translation of these responses to actual access to medicine practices.

In this paper we make a proposal for reforming biomedical research that is aimed to align re-search more closely with the so-called fair-share principle according to which the proportions of global resources as-signed to different diseases should agree with the ratios of human suffering associated with those diseases.

Good reasoning can lead to success; bad reasoning can lead to catastrophe. Yet, it's not obvious how we reason, and why we make mistakes. This new book by one of the pioneers of the field, Philip Johnson-Laird, looks at the mental processes that underlie our reasoning. It provides the most accessible account yet of the science of reasoning.

The hypothesis of extended cognition (HEC) claims that the cognitive processes that materially realise thinking are sometimes partially constituted by entities that are located external to an agent’s body in its local envi- ronment. We show how proponents of HEC need not claim that an agent must have a central nervous system, or physically instantiate processes organised in such a way as to play a causal role equivalent to that of the brain if that agent is to be capable of (...) cognition. Focusing on the case of spatial memory, we make our argument by taking a close look at the striking example of Physarum Polycephalum plasmodium (i.e., slime mould) which uses self- produced non-living extracellular slime trails to navigate its environment. We will argue that the use of exter- nalized spatial memory by basal organisms like Physarum is an example of extended cognition. Moreover, it is a possible evolutionary precursor to the use of internal spatial memory and recall in animals thus demonstrating how extended cognition may have emerged early in evolutionary history.

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

It has recently been suggested that the type/token theorist concerning musical works cannot come up with an adequate semantic theory of those sentences in which we purport to talk about such works. Specifically, it has been claimed that, since types are abstract entities, a type/token theorist can only account for the truth of sentences such as “The 1812 Overture is very loud” and “Bach's Two Part Invention in C has an F-sharp in its fourth measure” by adopting an untenable semantic (...) claim: namely, that the predicates in such sentences, once applied to musical works, undergo a systematic shift in their meanings. This article is a sustained explanation of why our talk about musical works in fact provides no problem for the type/token theorist. First, we demonstrate that the aforementioned “meaning shift” approach to the sentences’ predicates is well motivated and very credible. Second, we explain how the type/token theorist can adopt the best available version of an alternative, generic quantificational approach to such sentences. Third, we establish that other semantic theories, presented as undermining the type/token theory by giving us a reason for adopting eliminativism about types, are much less theoretically virtuous than the two theories that a type/token theorist can freely adopt.

During the last few decades, most cultural critics have come to agree that the division between "high" and "low" art is an artificial one, that Beethoven's Ninth and "Blue Suede Shoes" are equally valuable as cultural texts. In Who Needs Classical Music?, Julian Johnson challenges these assumptions about the relativism of cultural judgements. The author maintains that music is more than just "a matter of taste": while some music provides entertainment, or serves as background noise, other music claims (...) to function as art. This book considers the value of classical music in contemporary society, arguing that it remains distinctive because it works in quite different ways to most of the other music that surrounds us. This intellectually sophisticated yet accessible book offers a new and balanced defense of the specific values of classical music in contemporary culture. Who Needs Classical Music? will stimulate readers to reflect on their own investment (or lack of it) in music and art of all kinds. (shrink)

Miscommunication phenomena such as repair in dialogue are important indicators of the quality of communication. Automatic detection is therefore a key step toward tools that can characterize communication quality and thus help in applications from call center management to mental health monitoring. However, most existing computational linguistic approaches to these phenomena are unsuitable for general use in this way, and particularly for analyzing human–human dialogue: Although models of other-repair are common in human-computer dialogue systems, they tend to focus on specific (...) phenomena, missing the range of repair and repair initiation forms used by humans; and while self-repair models for speech recognition and understanding are advanced, they tend to focus on removal of “disfluent” material important for full understanding of the discourse contribution, and/or rely on domain-specific knowledge. We explain the requirements for more satisfactory models, including incrementality of processing and robustness to sparsity. We then describe models for self- and other-repair detection that meet these requirements and investigate how they perform on datasets from a range of dialogue genres and domains, with promising results.

Research on personality psychology is making important contributions to psychological science and applied psychology. This second edition of The Cambridge Handbook of Personality Psychology offers a one-stop resource for scientific personality psychology. It summarizes cutting-edge personality research in all its forms, including genetics, psychometrics, social-cognitive psychology, and real-world expressions, with informative and lively chapters that also highlight some areas of controversy. The team of renowned international authors, led by two esteemed editors, ensures a wide range of theoretical perspectives. Each research (...) area is discussed in terms of scientific foundations, main theories and findings, and future directions for research. The handbook also features advances in technology, such as molecular genetics and functional neuroimaging, as well as contemporary statistical approaches. An invaluable aid to understanding the central role played by personality in psychology, it will appeal to students, researchers, and practitioners in psychology, behavioral neuroscience, and the social sciences.

Despite the incremental nature of Dynamic Syntax, the semantic grounding of it remains that of predicate logic, itself grounded in set theory, so is poorly suited to expressing the rampantly context-relative nature of word meaning, and related phenomena such as incremental judgements of similarity needed for the modelling of disambiguation. Here, we show how DS can be assigned a compositional distributional semantics which enables such judgements and makes it possible to incrementally disambiguate language constructs using vector space semantics. Building on (...) a proposal in our previous work, we implement and evaluate our model on real data, showing that it outperforms a commonly used additive baseline. In conclusion, we argue that these results set the ground for an account of the non-determinism of lexical content, in which the nature of word meaning is its dependence on surrounding context for its construal.

I highly recommend Philosophy of Psychedelics by Chris Letheby to both the public and academics who want to dig deeper into the modern therapeutic science of psychedelics. In this piece, I will draw attention to key topics covered in the book that I judge as particularly compelling and likely to influence psychedelic therapy and our understanding of it going forward. Clearly, the importance of philosophy in the modern psychedelic therapy renaissance will increase, and Letheby’s Philosophy of Psychedelics will hold a (...) place as a foundational work helping to shape this future.

This dialogue discusses a proposal for the legalization of torture under specific circumstances and contrasts it with arguments for a total ban on torture. We consider three types of objection: first, that the difficulty of having adequate knowledge renders the stock “ticking bomb” scenario such a low-probability hypothetical as to present no realistic threat to a policy banning all torture; second, that empirically the information gleaned from torture is so unlikely to be reliable that it could not justify the moral (...) risk; and third, that sanctioning torture, even if only under the most extreme circumstances, would generate a ‘culture of torture,’ hence undermining fragile advances in international human rights rooted in unwavering commitment to human dignity. Compelling as these arguments appear, not all the conversants are wholly convinced by them; to this extent the dialogue ends aporetically. (shrink)

In a fictional conversation designed to appeal to both working teachers and social philosophers, three educators take up the question of whether critical thinking itself can, or should, be taught independently of an explicit consideration of issues related to social justice. One, a thoughtful but somewhat traditional Enlightenment rationalist, sees critical thinking as a neutral set of skills and dispositions, essentially unrelated to the conclusions of morality, problems of social organization, or the content of any particular academic discipline. A second (...) interlocutor, steeped in “critical” pedagogy of Paulo Freire, insists that the problem is the pose of neutrality itself. On this view, all honest and effective approaches to teaching must confront the hegemony of unjust relationships, institutions, and conceptual schemes. The third character attempts to resolve the tension between these two opposed camps. (shrink)

How do people make deductions? The orthodox view in psychology is that they use formal rules of inference like those of a “natural deduction” system.Deductionargues that their logical competence depends, not on formal rules, but on mental models. They construct models of the situation described by the premises, using their linguistic knowledge and their general knowledge. They try to formulate a conclusion based on these models that maintains semantic information, that expresses it parsimoniously, and that makes explicit something not directly (...) stated by any premise. They then test the validity of the conclusion by searching for alternative models that might refute the conclusion. The theory also resolves long-standing puzzles about reasoning, including how nonmonotonic reasoning occurs in daily life. The book reports experiments on all the main domains of deduction, including inferences based on prepositional connectives such as “if” and “or,” inferences based on relations such as “in the same place as,” inferences based on quantifiers such as “none,” “any,” and “only,” and metalogical inferences based on assertions about the true and the false. Where the two theories make opposite predictions, the results confirm the model theory and run counter to the formal rule theories. Without exception, all of the experiments corroborate the two main predictions of the model theory: inferences requiring only one model are easier than those requiring multiple models, and erroneous conclusions are usually the result of constructing only one of the possible models of the premises.

This article provides an account of the ethical issues that arise when digital technologies and online spaces are structured by Big Data algorithms. We show that although the uses of Big Data may be new, traditional theological and ethical categories are still applicable, including “the sins of the fathers” from hamartiology and the scholastic concept of haecceity. Using these resources, we map the overall ecosystem in which digital technologies are developed and used, identifying the relationships between the individuals and organizations (...) involved. We show how these relationships are often characterized by various kinds of harm. We then argue for a reorientation of the tech ecosystem toward co‐liberation—and ultimately, joy. (shrink)

This article outlines a theory of naive probability. According to the theory, individuals who are unfamiliar with the probability calculus can infer the probabilities of events in an extensional way: They construct mental models of what is true in the various possibilities. Each model represents an equiprobable alternative unless individuals have beliefs to the contrary, in which case some models will have higher probabilities than others. The probability of an event depends on the proportion of models in which it occurs. (...) The theory predicts several phenomena of reasoning about absolute probabilities, including typical biases. It correctly predicts certain cognitive illusions in inferences about relative probabilities. It accommodates reasoning based on numerical premises, and it explains how naive reasoners can infer posterior probabilities without relying on Bayes's theorem. Finally, it dispels some common misconceptions of probabilistic reasoning. (shrink)

At a time of COVID-19 pandemic, universal basic income (UBI) has been presented as a potential public health ‘upstream intervention’. Research indicates a possible impact on health by reducing poverty, fostering health-promoting behaviour and ameliorating biopsychosocial pathways to health. This novel case for UBI as a public health measure is starting to receive attention from a range of political positions and organisations. However, discussion of the ethical underpinnings of UBI as a public health policy is sparse. This is depriving policymakers (...) of clear perspectives about the reasons for, restrictions to and potential for the policy’s design and implementation. In this article, we note prospective pathways to impact on health in order to assess fit with Rawlsian, capabilities and perfectionist approaches to public health policy. We suggest that Raz’ pluralist perfectionist approach may fit most comfortably with the prospective pathways to impact, which has implications for allocation of resources. (shrink)

RESUMEN Una vez que el foco de la reflexión pasa de las teorías ideales a la aplicación de la justicia social, centrada en las instituciones de las sociedades democráticas, se requiere prestar especial atención a los estilos de vida. Estos tienen una alta incidencia en cómo la justicia es realizada y afectan tanto a la desigualdad económica como a la disponibilidad de los recursos naturales. En nuestras sociedades es posible establecer restricciones a los estilos de vida, especialmente en aquellos casos (...) en que, por el efecto de algunas dinámicas sociales, aquellos se desacoplan de las concepciones del bien. Se defiende que, en tales casos, la base normativa que permite exigir el respeto a los estilos de vida se disuelve y por ello es posible justificar su restricción. ABSTRACT Now that the focus of reflection has shifted from ideal theories to the application of social justice, centered on the institutions of democratic societies, it is necessary to pay special attention to lifestyles, since they not only influence the realization of justice, but also have an effect on economic inequality and the availability of natural resources. In our societies, it is possible to place restrictions on lifestyles, especially in those cases in which, influenced by certain social dynamics, they disengage from conceptions of the good. The article argues that, in those cases, the normative base grounding the demand that lifestyles be respected is dissolved, thus justifying their restriction. (shrink)

We report three experimental studies of reasoning with double conditionals, i.e. problems based on premises of the form: If A then B. If B then C. where A, B, and C, describe everyday events. We manipulated both the logical structure of the problems, using all four possible arrangements (or ''figures" of their constituents, A, B, and C, and the believability of the two salient conditional conclusions that might follow from them, i.e. If A then C , or If C then (...) A . The experiments showed that with figures for which there was a valid conclusion, the participants more often, and more rapidly, drew the valid conclusion when it was believable than when it was unbelievable. With figures for which there were no valid conclusions, the participants tended to draw whichever of the two conclusions was believable. These results were predicted by the theory that reasoning depends on constructing mental models of the premises. (shrink)

We live in a world that is increasingly shaped by and bathed in science, with most scientific progress occurring in the past century, and much of it in the past few decades. Yet, several authors have puz- zled over the observation that modern societies are also characterized by a high degree of belief in a variety of pseudoscientific claims that have been thoroughly debunked or otherwise discarded by scientists (Anonymous, 2001; Ede, 2000).

The authors outline a theory of conditionals of the form If A then C and If A then possibly C. The 2 sorts of conditional have separate core meanings that refer to sets of possibilities. Knowledge, pragmatics, and semantics can modulate these meanings. Modulation can add information about temporal and other relations between antecedent and consequent. It can also prevent the construction of possibilities to yield 10 distinct sets of possibilities to which conditionals can refer. The mental representation of a (...) conditional normally makes explicit only the possibilities in which its antecedent is true, yielding other possibilities implicitly. Reasoners tend to focus on the explicit possibilities. The theory predicts the major phenomena of understanding and reasoning with conditionals. (shrink)

The doctrines and teachings of the Church of Jesus Christ of Latter-day Saints support and even demand a strong environmental ethic. Such an ethic is grounded in the inherent value of all souls and in God’s commandment of stewardship. Latter-day Saint doctrine declares that all living organisms have souls and explicitly states that the ability of creatures to know some degree of satisfaction and happiness should be honored. God’s own concern for the well-being and progress of all life, and His (...) sacrifice through Jesus Christ, illustrate the generous way that He expects His children to exercise their brief stewardship of this world. In addition, the important role nature has played in the religious lives of Latter-day Saint members, from the Prophet Joseph Smith to the present day, argues strongly for wilderness preservation as a spiritual resource for future generations.

Abstract Theories of induction in psychology and artificial intelligence assume that the process leads from observation and knowledge to the formulation of linguistic conjectures. This paper proposes instead that the process yields mental models of phenomena. It uses this hypothesis to distinguish between deduction, induction, and creative forms of thought. It shows how models could underlie inductions about specific matters. In the domain of linguistic conjectures, there are many possible inductive generalizations of a conjecture. In the domain of models, however, (...) generalization calls for only a single operation: the addition of information to a model. If the information to be added is inconsistent with the model, then it eliminates the model as false: this operation suffices for all generalizations in a Boolean domain. Otherwise, the information that is added may have effects equivalent (a) to the replacement of an existential quantifier by a universal quantifier, or (b) to the promotion of an existential quantifier from inside to outside the scope of a universal quantifier. The latter operation is novel, and does not seem to have been used in any linguistic theory of induction. Finally, the paper describes a set of constraints on human induction, and outlines the evidence in favor of a model theory of induction. (shrink)
