The present study used masked repetition priming to examine whether face representations can be accessed without attention. Two experiments using a face recognition task presented masked repetition and control primes in spatially unattended locations prior to target onset. Experiment 1 used the same images as primes and as targets and Experiment 2 used different images of the same individual as primes and targets. Repetition priming was observed across both experiments regardless of whether spatial attention was cued to the location of (...) the prime. Priming occurred for both famous and non-famous targets in Experiment 1 but was only reliable for famous targets in Experiment 2, suggesting that priming in Experiment 1 indexed access to view-specific representations whereas priming in Experiment 2 indexed access to view-invariant, abstract representations. Overall, the results indicate that subliminal access to abstract face representations does not rely on attention. (shrink)

This article considers the different kinds of learning that are appropriate for the rapidly expanding range of writing that constitutes an everyday part of most people's working lives. It discusses the importance and demands of everyday writing in work, and the role of formal education in preparing people for the localised learning about writing that is necessary upon entering work. It considers the issue of the transfer of knowledge, and argues that both metacognitive and conceptual understandings about writing are crucial (...) elements in enabling people to transfer and adapt foundation literacy skills to the workplace.

Australia is second only to Israel in being the world’s most culturally diverse nation, based largely on high levels of immigration in the second part of the 20th century. From the 1970s onwards, Australia formally recognized the massive social changes brought about by postwar immigration, and provided legislation to incorporate cultural diversity into everyday lives. One such ‘legislative’ enactment saw the establishment of multicultural broadcasting in Australia, as arguably a world-first, both in its comprehensiveness and diversity. Today, Australia has a (...) public sector corporation, the Special Broadcasting Service, administering five radio services in 68 languages. Also, the Community Radio sector produces multicultural programming in 100 languages through a number of its 330 broadcast and 207 narrowcast stations. This article examines the relationship between radio and its communities. It argues that despite the ‘profile’ of SBS television, radio is much closer to its constituent communities, and therefore plays a greater role in enabling those communities to speak their own histories, beyond the confines of a consensual Anglophile paradigm.

In higher-level cognitive tasks, older compared to younger adults show a bias towards positive emotion information and away from negative information (a positivity effect). It is unclear whether this effect occurs in early perceptual processing. This issue is important for determining if the positivity effect is due to automatic rather than controlled processing. We tested this with older and younger adults on a positive/negative face emotion valence classification task using masked priming. Positive (happy) and negative (angry) face targets were preceded (...) by masked repetition or valence primes with neutral face baselines. In Experiment 1, 30 younger and 30 older adults were tested with 50 ms primes. Younger adults showed repetition priming for both positive and negative targets. Older adults showed repetition priming for positive but not negative targets. Neither group showed valence priming. In Experiment 2, 30 older and 29 younger adults were tested with longer duration primes. Younger adults showed repetition priming for both positive and negative emotions, and no valence priming. Older adults only showed repetition and valence priming for positive targets. We proposed older adults’ lack of angry face priming was due to an early attention orienting strategy favouring happy expressions at the expense of angry ones. (shrink)

A growing body of evidence shows that brain oscillations track speech. This mechanism is thought to maximise processing efficiency by allocating resources to important speech information, effectively parsing speech into units of appropriate granularity for further decoding. However, some aspects of this mechanism remain unclear. First, while periodicity is an intrinsic property of this physiological mechanism, speech is only quasi-periodic, so it is not clear whether periodicity would present an advantage in processing. Second, it is still a matter of debate (...) which aspect of speech triggers or maintains cortical entrainment, from bottom-up cues such as fluctuations of the amplitude envelope of speech to higher level linguistic cues such as syntactic structure. We present data from a behavioural experiment assessing the effect of isochronous retiming of speech on speech perception in noise. Two types of anchor points were defined for retiming speech, namely syllable onsets and amplitude envelope peaks. For each anchor point type, retiming was implemented at two hierarchical levels, a slow time scale around 2.5 Hz and a fast time scale around 4 Hz. Results show that while any temporal distortion resulted in reduced speech intelligibility, isochronous speech anchored to P-centers (approximated by stressed syllable vowel onsets) was significantly more intelligible than a matched anisochronous retiming, suggesting a facilitative role of periodicity defined on linguistically motivated units in processing speech in noise.

In November 2018, the practice of health care ethics consultation crossed a major threshold when 138 candidates took the inaugural Healthcare Ethics Consultant Certification Examination. This accomplishment, long in the making, has had and continues to have both advocates and critics. The Healthcare Ethics Consultant Certification Commission, a functionally autonomous body created and funded by the American Society for Bioethics and Humanities, was charged with overseeing creation of the certification process, developing the exam, and formulating certification standards and policies to (...) assess candidates’ qualifications. In this essay, as members of the commission, we describe the process of developing, administering, and scoring the certification examination as well as the historical context and the outlook for certification. By detailing the decisions and actions of the commission, we aim to provide a transparent account of the commission's efforts to develop a psychometrically sound, reliable, and secure examination through a deliberative, fair, and data‐driven process.

We investigate the causal effects of religious service attendance on prosocial behaviours using longitudinal data from a nationally representative sample of 33,198 New Zealanders collected between 2018 and 2021. Our study innovates in three ways: (1) we use longitudinal rather than cross-sectional data; (2) we incorporate measures of help received alongside self-reported giving; and (3) our statistical models are designed to address causal questions, rather than simply to describe change over time. We model causal contrasts for three hypothetical interventions – (...) increasing, decreasing, or maintaining religious service attendance – and assess their effects on eight distinct prosocial domains. Study 1 focuses on self-reported charitable donations and volunteering. Studies 2 and 3 examine receiving help – both personal and financial – from family, friends, and the wider community. Across all analyses, we find that the causal effects of religious service attendance are notably smaller than cross-sectional correlations suggest. However, even modest increases in regular attendance would result in charitable donations equivalent to approximately 4% of the New Zealand Government’s annual spending – a considerable public benefit. By applying robust methods for causal inference to national-scale panel data, our study provides insights that can inform public policy about the social functions of religious participation and advances a methodological framework for investigating the social consequences of cultural practices.

COVID-19 is unique in that it is the first global pandemic occurring amidst a crowded information environment that has facilitated the proliferation of misinformation on social media. Dangerous misleading narratives have the potential to disrupt ‘official’ information sharing at major government announcements. Using an interrupted time-series design, we test the impact of the announcement of the first UK lockdown on short-term trends of misinformation on Twitter. We utilise a novel dataset of all COVID-19-related social media posts on Twitter from the (...) UK 48 hours before and 48 hours after the announcement. We find that while the number of tweets increased immediately post announcement, there was no evidence of an increase in misinformation-related tweets. We found an increase in COVID-19-related bot activity post-announcement. Topic modelling of misinformation tweets revealed four distinct clusters: ‘government and policy’, ‘symptoms’, ‘pushing back against misinformation’ and ‘cures and treatments’. (shrink)

Background There is a need for interdisciplinary research to better understand how pedagogical approaches in primary physical education (PE) can support the linked development of physical, cognitive and affective aspects of physical literacy and physical activity behaviors in young children living in deprived areas. The Skill Acquisition Methods fostering Physical Literacy in Early-Physical Education (SAMPLE-PE) study aims to examine the efficacy of two different pedagogies for PE, underpinned by theories of motor learning, to foster physical literacy. Methods SAMPLE-PE will be (...) evaluated through a cluster-randomized controlled trial targeting 5–6 year old children from schools located in areas of high deprivation in Merseyside, North-West England. Schools will be randomly allocated to one of three conditions: Linear Pedagogy, Non-linear Pedagogy, or Control. Non-linear and Linear Pedagogy intervention primary schools will receive a PE curriculum delivered by trained coaches over 15 weeks, while control schools will follow their usual practice. Data will be collected at baseline (T0), immediately post-intervention (T1), and 6 months after the intervention has finished (T2). Children’s movement competence is the primary outcome in this trial. Secondary outcomes include physical activity, perceived competence, motivation, executive functions, and self-regulation. An extensive process evaluation will also examine implementation factors such as intervention context, reach, dose, fidelity and acceptability. Discussion The SAMPLE-PE project will enable better understanding surrounding how to operationalise physical literacy through enrichment of PE practices in early PE. The study will provide robust scientific evidence regarding the efficacy of underpinning PE pedagogy with theories of motor learning to promote the development of physical literacy.

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false.

This paper develops and defends a novel version of a relatively neglected category of theory of the nature of happiness: the desire-satisfaction theory. My account is similar in its fundamentals to Wayne Davis’s theory of happiness-as-subjective-desire-satisfaction. After arguing that this is the best general way to proceed for the desire-based approach, I develop an improved version of subjective desire satisfactionism in light of recent arguments in the happiness literature.

The use of $Nepomnja\check{s}\check{c}i\check{i}'s$ Theorem in the proofs of independence results for bounded arithmetic theories is investigated. Using this result and similar ideas, it is shown that at least one of S1 or TLS does not prove the Matiyasevich-Robinson-Davis-Putnam Theorem. It is also established that TLS does not prove a statement that roughly means nondeterministic linear time is equal to co-nondeterministic linear time. Here S1 is a conservative extension of the well-studied theory IΔ0 and TLS is a theory for (...) LOGSPACE reasoning. (shrink)

There remains a concern in philosophy of education circles to assert that teaching is a social practice. Its initiation occurs in a conversation between Alasdair MacIntyre and Joe Dunne which inspired a Special Issue of the Journal of Philosophy of Education. This has been recently utilised in a further Special Issue by Chris Higgins. In this article I consider two points of conflict between MacIntyre and Dunne and seek to resolve both with a more nuanced understanding of the implications (...) of applying the concept ‘social practice’ to teaching. I critique both Dunne's and Higgins' focus on schools and school teaching. It is their focus on school teaching, rather than a broader account of teaching, that leads them astray. The result is that Dunne and Higgins have not shown that teaching is a social practice. School teaching is not a complex activity, but a complex set of different activities co-located in one place and engaged in by the same agents. In a final section I offer an account of ‘school teaching’ as a multi-practice activity which is consistent with MacIntyre's approach, and argue that schoolteachers have both an institutional and an educative role.

Western philosophy’s relationship with prisons stretches from Plato’s own incarceration to the modern era of mass incarceration. Philosophy Imprisoned: The Love of Wisdom in the Age of Mass Incarceration draws together a broad range of philosophical thinkers, from both inside and outside prison walls, in the United States and beyond, who draw on a variety of critical perspectives (including phenomenology, deconstruction, and feminist theory) and historical and contemporary figures in philosophy (including Kant, Hegel, Foucault, and Angela Davis) to think (...) about prisons in this new historical era. All of these contributors have experiences within prison walls: some are or have been incarcerated, some have taught or are teaching in prisons, and all have been students of both philosophy and the carceral system. The powerful testimonials and theoretical arguments are appropriate reading not only for philosophers and prison theorists generally, but also for prison reformers and abolitionists. (shrink)

Revised version of the author's dissertation--Emory University, 2011.

Heidegger's writings are among the most formidable in the philosophy. The pivotal concepts of his thought are for many the source of both fascination and frustration. This title includes chapters that introduce and explain a key Heideggerian concept, or a cluster of closely related concepts.

A fundamental cognitive function found across a wide range of species and necessary for survival is the ability to navigate complex environments. It has been suggested that mobility may play an important role in the development of spatial skills. Despite evolutionary arguments offering logical explanations for why sex/gender differences in spatial abilities and mobility might exist, thus far there has been limited sampling from nonindustrialized and subsistence-based societies. This lack of sampling diversity has left many unanswered questions regarding the effects (...) that environmental variation and cultural norms may have in shaping mobility patterns during childhood and the development of spatial competencies that may be associated with it. Here we examine variation in mobility, performance on large-scale spatial skills, and performance on small-scale spatial skills among Twa forager/pastoralist children whose daily lives have been dramatically altered since settlement and the introduction of government-funded boarding schools. Unlike in previous findings among Twa adults, boys and girls show similar patterns of travel on all measures of mobility. We also find no significant differences in spatial task performance by gender for large- or small-scale spatial skills. Further, children performed as well as adults did on mental rotation, and they outperformed adults on the water-level task. We discuss how children’s early learning environments may influence the development of both large- and small-scale spatial skills. (shrink)

To understand the prospects for global order and progress in the coming years, we explore the joint implications of three premises: (1) states advantaged by the current international order have stakes in its regularity and predictability, and thus in moving to counter or prevent threats to those stakes; (2) along impure public and club goods lines, they are more likely to make efforts to do so when some private or club benefits result; and (3) public opinion provides a bounded policy (...) acceptance envelope offering incentives and disincentives to national political elites to act as envisioned by the first two premises. We present a mosaic of public opinion in major OECD countries (the US, Japan, and major EU members) on three policy areas that contain international public goods elements. Actual contribution tendencies in those areas found in our previous work largely conform to the public opinion patterns reported here. Within the limits of available data, domestic political incentives as represented by public opinion warrant neither extreme optimism nor pessimism about the prospects for continuing contributions by OECD states to sustaining orderly functioning of the current world system.

This paper proposes that the meanings of some natural language expressions should be thought of as functions on their own continuations. Continuations are a well-established analytic tool in the theory of programming language semantics; in brief, a continuation is the entire default future of a computation. I show how a continuation-based grammar can unify several aspects of natural language quantification in a new way: merely stating the truth conditions for quantificational expressions in terms of continuations automatically accounts for scope displacement (...) and scope ambiguity. To prove this claim, I exhibit a simple finite context-free grammar with a strictly compositional semantics in which quantificational NPs are interpreted in situ but take semantic scope over larger constituents. There is no Quantifier Raising (nor any use of a level of Logical Form distinct from overt syntax), no Cooper Storage (or similar mechanisms used in many recent HPSG, Categorial, or Type-logical treatments), and no need for type-shifting (as in Hendriks' Flexible Types account). Continuations also provide a natural account of generalized coordination that does not require either type-shifting or type polymorphism. Compositionality issues are discussed in some detail.

Wayne Davis presents a highly original approach to the foundations of semantics, showing how the so-called "expression" theory of meaning can handle names and other problematic cases of nondescriptive meaning. The fact that thoughts have parts ("ideas" or "concepts") is fundamental: Davis argues that like other unstructured words, names mean what they do because they are conventionally used to express atomic or basic ideas. In the process he shows that many pillars of contemporary philosophical semantics, from twin earth (...) arguments to the necessity of identity, are unfounded. (shrink)

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

BackgroundThere has been no in-depth research of public attitudes on withholding or withdrawing life-prolonging treatment, euthanasia, assisted suicide and physician assisted suicide in Croatia. The aim of this study was to examine these attitudes and their correlation with sociodemographic characteristics, religion, political orientation, tolerance of personal choice, trust in physicians, health status, experiences with death and caring for the seriously ill, and attitudes towards death and dying. MethodsA cross-sectional study was conducted on a three-stage random sample of adult citizens of (...) the Republic of Croatia, stratified by regions, counties, and locations within those counties. In addition to descriptive statistics, ANOVA and Chi-square tests were used to determine differences, and factor analysis, correlation analysis and multiple regression analysis for data analysis.Results38.1% of the respondents agree with granting the wishes of dying people experiencing extreme and unbearable suffering, and withholding life-prolonging treatment, and 37.8% agree with respecting the wishes of such people, and withdrawing life-prolonging treatment. 77% of respondents think that withholding and withdrawing procedures should be regulated by law because of the fear of abuse. Opinions about the practice and regulation of euthanasia are divided. Those who are younger and middle-aged, with higher levels of education, living in big cities, and who have a more liberal worldview are more open to euthanasia. Assisted suicide is not considered to be an acceptable practice, with only 18.6% of respondents agreeing with it. However, 40.1% think that physician assisted suicide should be legalised. 51.6% would support the dying person’s autonomous decisions regarding end-of-life procedures.ConclusionsThe study found low levels of acceptance of withholding or withdrawing life-prolonging treatment, euthanasia, assisted suicide and physician assisted suicide in Croatia. In addition, it found evidence that age, level of education, political orientation, and place of residence have an impact on people’s views on euthanasia. There is a need for further research into attitudes on different end-of-life practices in Croatia. (shrink)

An urgent account of the state of our oceans today--and what we must do to protect them The ocean sustains life on our planet, from absorbing carbon to regulating temperatures, and, as we exhaust the resources to be found on land, it is becoming central to the global market. But today we are facing two urgent challenges at sea: massive environmental destruction and spiraling inequality in the ocean economy. Chris Armstrong reveals how existing governing institutions are failing to respond (...) to the most pressing problems of our time, arguing that we must do better. Armstrong examines these crises--from the fate of people whose lands will be submerged by sea level rise to the exploitation of people working in fishing to the rights of marine animals--and makes the case for a powerful World Ocean Authority capable of tackling them. A Blue New Deal presents a radical manifesto for putting equality, democracy, and sustainability at the heart of ocean politics. (shrink)

Over the past decade, the number of clinical trials registered with the Food and Drug Administration has increased dramatically. The business of clinical research has become more diverse, involving academic institutions, clinician-researchers in community settings, pharmaceutical companies, and contract research organizations. This growth has been accompanied by increasing concerns about the ethical conduct of research. Much of this concern has been directed to procedural issues including institutional review board review, data monitoring, and informed consent forms. However, the protection of human (...) subjects cannot be achieved by relying solely on procedural safeguards. There are more nuanced issues related to recruitment and retention of subjects, and to the process of informed consent, that are generated during the interaction between study staff and subjects. It is only through an examination of these relationships that one can more fully define and understand the challenges of protecting subjects in research. (shrink)

J. S. Mill is typically thought of as a liberal utilitarian disciple of Jeremy Bentham, and in other readings as a modern Socratic or even a modern Epicurean. Mill and the Epicureans are alike in several respects: they theorize personal freedom and active character versus determinism and passivity, they oppose excessive love and praise friendship, and they are critical of traditional religiosity. In spite of these similarities, Mill and the Epicureans have a different conception of active character and citizenship, stemming (...) from a difference in first principles. Mill's philosopher does not share the Epicurean aim of untroubledness (ataraxia), and Mill accepts the demanding task of educating and regenerating a mass democratic society. Below, I assess Mill's troubled hedonism, that is, his acceptance of often intense and long-term mental perturbations, justified by a decidedly non-Epicurean social reform project. (shrink)
