Though we see the potential for benefits from the development of process-oriented approaches, we argue that it falls prey to many of the same critiques raised about the existing construct level of analysis. The construct-level approach will likely dominate motivation research until we develop computational models that are not only accurate, but also broadly usable.

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

The modern ethical framework demands informed consent for research participation that includes disclosure of material information, as well as alternatives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (COVID-19) results in illness that often involves rapid deterioration. Despite the urgent need to find therapy, obtaining informed consent for COVID-19 research is needed. The current pandemic presents three types of challenges for investigators faced with obtaining informed consent for research participation: (1) uncertainty over key information to informed consent, (2) time (...) and pressure constraints, and (3) obligations regarding disclosure of new alternative therapies and re-consent. To mitigate consenting challenges, primary investigators need to work together to jointly promote urgent care and research into COVID-19. Actions they can take include (1) prior plan addressing ways to incorporate clinical research into clinical practice in emergency, (2) consider patients vulnerable with early deliberation on the consent process, (3) seek Legally Authorized Representatives (LARs), (4) create a collaborative research teams, (5) aim to consent once, despite evolving information during the pandemic, and (6) aim to match patients to a trial that will most benefit them. The COVID-19 pandemic both exacerbates existing challenges and raises unique obstacles for consent that require forethought and mindfulness to overcome. While research teams and clinician-investigators will need to be sensitive to their own contexts and adapt solutions accordingly, they can meet the challenge of obtaining genuinely informed consent during the current pandemic.

We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

The collected essays and consensus statements of the second round of the National Evangelical-Catholic Dialogue, and the second book of the series on Evangelicals and Catholics in dialogue. The essays address the Christian ideal of life lived in pursuit of the good that is God, and the witness and imitation of God's action in Christ, as a pathway to fruitful dialogue between Catholics and Evangelicals.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a unique psychopharmacological model that leverages the profound effects of the psychedelic experience. That experience is characterized by strong dependency on two key factors: participant mindset and the therapeutic environment. As such, therapeutic models that utilize psychedelics reflect the need for careful design that promotes (...) an open, flexible, trusting mindset and a supportive setting. To meet this need, the PP model is increasingly supplemented by auxiliary methods, including meditation, relaxation, visualization or spiritual practices. We suggest virtual reality (VR) as a full-spectrum tool able to capitalize on and catalyze the innately therapeutic aspects of the psychedelic experience, such as detachment from familiar reality, alteration of self-experience, augmentation of sensory perception and induction of mystical-type experiences. This is facilitated by VR’s evidenced capacity to: aid relaxation and reduce anxiety; buffer from external stimuli; promote a mindful presence; train the mind to achieve altered states of consciousness (ASC); evoke mystical states; enhance therapeutic alliance and encourage self-efficacy. While these unique VR features appear promising, VR’s potential role in PP remains speculative due to lack of empirical evidence on the combined use of VR and PP. Given the increased commercial interest in this synergy there is an urgent need to evaluate this approach. We suggest specific VR models and their role within PP protocols to inspire future direction in scientific research, and provide a list of potential disadvantages, side effects and limitations that need to be carefully considered. These include sensory overstimulation, cyber-sickness, triggering memories of past traumatic events as well as distracting from the inner experience or strongly influencing its contents. A balanced, evidence-based approach may provide continuity across all phases of treatment, support transition into and out of an ASC, deepen acute ASC experiences including mystical states and enrich the psychotherapeutic process of integration. We conclude that the potential application of VR in modulating psychedelic-assisted psychotherapy demands further exploration and an evidence-based approach to both design and implementation.

Though almost forty years have elapsed since its first publication, it is a testament to the philosophical acumen of its author that 'The Matter of Chance' contains much that is of continued interest to the philosopher of science. Mellor advances a sophisticated propensity theory of chance, arguing that this theory makes better sense than its rivals (in particular subjectivist, frequentist, logical and classical theories) of ‘what professional usage shows to be thought true of chance’ (p. xi) – in particular ‘that (...) chance is objective, empirical and not relational, and that it applies to the single case’ (ibid.). The book is short and dense, with the serious philosophical content delivered thick and fast. There is little by way of road-mapping or summarising to assist the reader: the introduction is hardly expansive and the concluding paragraph positively perfunctory. The result is that the book is often difficult going, and the reader is made to work hard to ensure correct understanding of the views expressed. On the other hand, the author’s avoidance of unnecessary use of formalism and jargon ensures that the book is still reasonably accessible. In the following, I shall first summarise the key features of Mellor’s propensity theory, and then offer a few critical remarks. (shrink)

ABSTRACT: McDowell argues that the shortcomings of recent theories of experience are the product of the modern scientistic conception of nature. Reconceive nature, he suggests, and we can explain how perceptual experience can be an external constraint on thought that, moreover, has conceptual import. In this article I argue that McDowell’s project is unsuccessful. Those wishing to construct normative theories, including theories of perceptual experience, face the normative trilemma—they must choose one of three styles of theory, each of which exhibits (...) a distinctive weakness. If we view McDowell’s approach in light of this choice, we see that he cannot adequately explain the link between experience and the world itself. I conclude that the real problem with theories of experience flows not from scientistic naturalism, but rather from the inconsistent demands we place on normative theories in general.RÉSUMÉ: McDowell soutient que les défauts des théories récentes sur l’expérience sont engendrés par la position scientifique moderne sur la nature. En reconcevant la nature, suggère-t-il, on est en mesure d’expliquer comment l’expérience sensorielle peut être une contrainte extérieure sur la pensée, contrainte qui joue, de plus, un rôle conceptuel. Je soutiens dans cet article que le projet de McDowell se solde par un échec. Ceux qui souhaitent élaborer des théories normatives, y compris des théories sur l’expérience sensorielle, font face au trilemme normatif — ils doivent choisir un type de théorie parmi trois types qui trahissent tous une faiblesse particulière. Si l’on envisage la démarche de McDowell dans la perspective de ce choix, on s’aperçoit qu’il ne peut expliquer de manière satisfaisante le lien entre l’expérience et le monde lui-même. J’en conclus que le véritable problème des théories sur l’expérience ne découle pas du naturalisme scientifique, mais plutôt des exigences incohérentes auxquelleson soumet les théories normatives en général.

What are the relationships between doubt and truth, thinking and writing in Montaigne’s Essais? We usually see Montaigne’s doubt through the lens of ancient schools of Scepticism and yet he notes that the Pyrrhonians ‘ne peuvent exprimer leur generale conception en aucune maniere de parler’: these philosophers describe their doubtful thought in negative affirmations but these are affirmations – ‘propositions affirmatives’ – all the same. This thesis approaches Montaigne’s doubt differently: I investigate the Essais not as an attempt to indicate (...) or describe doubtful, ‘double et divers’ thought but as a tool for thinking doubtfully in writing. Montaigne’s literary use of language is therefore central to my analysis. Irony, ambiguity, the practices of rewriting and overwriting, the ‘polyphony’ of cited authors who advocate different positions: these afford ways of thinking that sustain duality and doubt. I focus on Montaigne’s engagement with Seneca and Plutarch, ancient authors who are, superficially, unrelated to doubt: the Essais constitute a particular form of humanistic engagement with ancient texts, concerned with practices and forms of writing as much as, if not more than, with philosophical concepts. These ‘dogmatic’ authors – they defend philosophical positions of certainty – were, counter-intuitively, seen by Montaigne to have a ‘forme d’escrire douteuse et irresolue’. This doubtful ‘forme’ shaped Montaigne’s own and it was, I argue, in working with and on these authors – reading, writing, and thinking with them – that he constructed a way of writing doubtful in both form and thought: a text that is double, unresolved, ambiguous, and yet ‘truthful’ in its capacity to perform and make legible the complex, multiple nature of his thought and his thinking.

This Ph.D. thesis explores a novel way of thinking about computation in cognitive science. It argues for what I call ‘the mechanistic account of wide computationalism’, or simply wide mechanistic computation. The key claim is that some cognitive and perceptual abilities are produced by or are the result of computational mechanisms that are, in part, located outside the individual; that computational systems, the ones that form the proper units of analysis in cognitive science, are particular types of functional mechanisms that, (...) on occasion, spread out across brain, body, and world. Wide mechanistic computation is the result of bringing together two distinct strands of thinking about computation: ‘wide’ views, which hold that computational systems can, on occasion, include parts of the surrounding environment; and ‘mechanistic’ views, which hold that computational explanation is a species of mechanistic explanation, and that computational mechanisms are a special type of functional mechanism. I argue that wide mechanistic computation draws support from several sources. First, I examine research on animal and human psychology and show that several organisms’ behaviours are properly treated as being the output of wide computational mechanisms. Second, I defend the view from several philosophical charges, including worries about its explanatory parsimony and empirical testability. Finally, I argue for the view’s theoretical credentials by showing that it can help resolve specific problems that have recently troubled 4E cognition. The result is an argument for not only the coherence but also empirical plausibility of wide mechanistic computation. On route to its main objective, the thesis also accomplishes a number of related tasks, including: providing a framework for organising and conceptualising different views of computation, securing the conceptual foundations of mechanistic computation by addressing an outstanding challenge called the ‘abstraction problem’, sounding a cautionary note about recent predictive processing accounts of extended cognition and arguing against a particular conception of levels often used within cognitive science, what is labelled the ‘hierarchical correspondence view of levels’.

The popularization of neuroscientific ideas about learning—sometimes legitimate, sometimes merely commercial—poses a real challenge for classroom teachers who want to understand how children learn. Until teacher preparation programs are reconceived to incorporate relevant research from the neuro- and cognitive sciences, teachers need translation and guidance to effectively use information about the brain and cognition. Absent such guidance, teachers, schools, and school districts may waste time and money pursuing so called brain-based interventions that lack a firm basis in research. Meanwhile, the (...) success of our schools will continue to be narrowly defined by achievement standards that ignore knowledge of the neural and cognitive processes of learning. To achieve the goals of neuroeducation, its proponents must address unique ethical issues that neuroeducation raises for five different groups of individuals: a) practicing teachers, b) neuroscience researchers whose work could inform education, c) publishers and the popular media, d) educational policy-makers, and e) university-level teacher educators. We suggest ways in which these ethical challenges can be met and provide a model for teacher preparation that will enable teachers themselves to translate findings from the neuro-and cognitive sciences and use legitimate research to inform how they design and deliver effective instruction.

In her article on ‘translating ngaka’ (diviner-healer), Musa Dube argues that in the writings of Robert Moffat and subsequently in his translation of the Bible into Setswana, the person of the ngaka, rather than being portrayed as occupying a central and positive role in Setswana culture, is relegated to a marginal position and is even depicted as evil and an imposter. The article seeks to argue that firstly, there is a fundamental connection between ngaka and bogwera in Setswana tradition. This (...) is because ngaka performed the rite of initiation and was a central figure in the circumcision (rupa) of those undergoing the rite of imitation. Secondly, in his 1857 English–Setswana Bible Moffat alters the word bogwera in Luke 2:21. In representing and translating bogwera as circumcision in Luke 2:21 Moffat rewrites and reorders the political, economic and religious beliefs of Batswana. It is in the transmogrification of bogwera in Luke 2:21 that an act of hybridisation and creolisation takes place through the ordering of the Batswana cosmology and culture. I would further argue that not only did this marginalisation colour the perceptions of the Batswana regarding bogwera, but also that the translated text was used as a tool to disrupt, marginalise, replace, subvert and colonise the spiritual spaces of the Batswana. Furthermore, the article attempts to critically engage with the translated text from an ideological criticism within postcolonial theory, engaging with the fundamental question: why did Moffat translate and alter bogwera as circumcision rather than using the proper word which is rupa (circumcision)? Selected letters published in the newspaper Mahoko a Becwana (Words of Batswana) are quoted and discussed, as it is in these letters that we are confronted with an act of hybridisation and creolisation. The letters also point to the effects of such a translation and transmogrification as a discursive tool to reorder and to pervert the Batswana cosmology and culture. In translating and altering circumcision as bogwera Moffat performs an act of mutation of meaning. It is in this morphing of bogwera into something that is charged with negativity in order to reorder and rewrite through an exercise of transmutation that Moffat attempts to subvert and to indoctrinate, resulting in the subversion of the spiritual spaces of Batswana.

In his 1840 translation of the Gospel of Luke from English into Setswana, Robert Moffat transfers Western numerals, geographic words and biblical names to Setswana. In this article, it is argued that in this translation, we see the beginning of the colonisation of Setswana. Furthermore, it is argued that in this translation, Moffat used epistemic privilege and the performance of power to facilitate the process of epistemicide on the linguistic heritage of Batswana and its indigenous knowledge system through an (...) act of colonisation.Contribution: The article applies an intersection of theoretical lenses, namely decoloniality and the Foucauldian notion of power, as its frames of reference in analysing the 1840 English–Setswana Gospel of Luke.

The 1840 gospel of Luke as translated by Moffat presents us with the cultural and imperial surveillance performed by a patriarchal system through the institutionalisation of motherhood and womanhood (bosadi). Motherhood or womanhood (bosadi) as a patriarchal institution has been a space in which patriarchal discursive practices have been realised through an act of politicising motherhood or womanhood. At the centre of this act of politicisation of motherhood or womanhood (bosadi) is the ability to carry and bear children (pelegi). (...) The institution of motherhood or womanhood has facilitated a binary between motherhood (bosadi) and bareness (moopa). The womb/popelo as a symbol of fertility becomes the space of mothering women, of labelling, categorising and naming women that the system locates as moopa or barren. The article seeks to reread the narrative on childbearing in the 1840 gospel of Luke from a decolonial framework. I will argue that childbearing, as a patriarchal institution, has been a space in which the gaze of patriarchy has been produced to subjugate women through cultural and imperial masculinist gaze. I will also argue that there is a need to decolonise and liberate such a space (womb) as not a determinant of motherhood. (shrink)
