Boundary extension is a memory phenomenon in which an individual reports seeing more of a scene than they actually did. We provide the first examination of boundary extension in individuals diagnosed with depression, hypothesising that an overemphasis on pre-existing schema may enhance boundary extension effects on emotional photographs. The relationship between boundary extension and overgeneralisation in autobiographical memory was also explored. Individuals with (n = 42) and without (n = 41) Major Depressive Disorder completed a camera paradigm task utilising positive, (...) negative, and neutral stimuli. Across all participants, positive (d = 0.37) and negative (d = 0.66) stimuli were extended more than neutral stimuli. This effect did not differ between depressed and never-depressed participants. Across all participants, images containing objects were extended more than images containing faces. An association was also evident between extension effects in memory for perceptual space and extensions of autobiographical memory across time. (shrink)

Detailed and in-depth investigation of the important but often unappreciated work done by science technicians, in this case in the context of paleontology.

In this paper, Caitlin Murphy Brust and Rebecca Taylor examine the responsibilities of college educators to resist conditions of epistemic injustice within their institutions. Pedagogy alone cannot bring about epistemic justice in higher education, for no individual epistemic agent can single-handedly transform their epistemic environment. The roots of such injustices are structural and thus require structural interventions. However, college educators do retain some agency to engage in epistemic resistance. Brust and Taylor argue that they can and should take steps (...) to foster just relations within the epistemic communities of their classrooms — calling for pedagogy that both recognizes the unjust features of the broader epistemic environment and responds to the unique forms of epistemic injustice that manifest in the classroom, with particular attention to seminar-style courses.

Philosophers of science are well aware that theories are underdetermined by data. But what about the data? Scientific data are selected and processed representations or pieces of nature. What is useless context and what is valuable specimen, as well as how specimens are processed for study, are not obvious or predetermined givens. Instead, they are decisions made by scientists and other research workers, such as technicians, that produce different outcomes for the data. Vertebrate fossils provide a revealing case of this (...) data-processing, because they are embedded in rock that often matches the fossils’ color and texture, requiring an expert eye to judge where the fossil/context interface is. Fossil preparators then permanently define this interface by chiseling away the material they identify as rock. As a result, fossil specimens can emerge in multiple possible forms depending on the preparator’s judgment, skill, and chosen tools. A prepared fossil then is not yet data but potential data, following Leonelli’s relational framework in which data are defined as evidence that scientists have used to support a proposed theory. This paper draws on ethnographic evidence to assess how scientists overcome this underdetermination of specimens, as potential data, in addition to the underdetermination of theories and of data, to successfully construct specimen-based knowledge. Among other strategies, paleontology maintains a division of labor between data-makers and theory-makers. This distinction serves to justify the omission of preparators’ nonstandard, individualized techniques from scientific publications. This separation has benefits for both scientists and technicians; however, it restricts knowledge production by preventing scientists from understanding how the pieces of nature they study were processed into researchable specimens.

This commentary on Haueis and Colaço's 'Metabolic considerations for cognitive modeling' emphasizes the importance of how we individuate cognitive capacities, operations, and vehicles. It challenges the target article’s reliance on mechanistic notions of computation and medium-independence, and uses examples from the memory literature to suggest that the role played by metabolic considerations in cognitive models will depend on questions of taxonomy and cognitive ontology.

Whether neurons represent or play a mere causal role is a foundational issue in philosophy of neuroscience. Evidence that neurons perform a representational role is weakened by the possibility of explaining experimental results by appeal to brute causal processes alone. Despite this, neuroscientists ascribe representational content to patterns of neural activity to explain experimental results. An important problem with this practice is determining which content to ascribe to the neural representation. One view is that researchers are only warranted in ascribing (...) the content determined by particular experimental results. An alternative view is that researchers are warranted in appealing to the broader research domain to determine the content of a putative neural representation. In this paper, I argue that both are warranted; either alone is insufficient. Using optogenetics research on memory engrams as a case study, I show how researchers ascribe content to neural representations and justify their approach. Whether a particular content ascription is warranted depends on particular experimental results, the broader research domain that is appealed to, and how results from various animal models, probes, and experimental paradigms are generalized.

Human development takes place in a social context. Two pervasive sources of social information are faces and hands. Here, we provide the first report of the visual frequency of faces and hands in the everyday scenes available to infants. These scenes were collected by having infants wear head cameras during unconstrained everyday activities. Our corpus of 143 hours of infant-perspective scenes, collected from 34 infants aged 1 month to 2 years, was sampled for analysis at 1/5 Hz. The major finding (...) from this corpus is that the faces and hands of social partners are not equally available throughout the first two years of life. Instead, there is an earlier period of dense face input and a later period of dense hand input. At all ages, hands in these scenes were primarily in contact with objects and the spatio-temporal co-occurrence of hands and faces was greater than expected by chance. The orderliness of the shift from faces to hands suggests a principled transition in the contents of visual experiences and is discussed in terms of the role of developmental gates on the timing and statistics of visual experiences.

This book proposes guidelines for constructing and evaluating definitions of terms, i.e. words or phrases of general application. The guidelines extend to adoption of nomenclature. The book is meant to be a practical guide for people who find themselves in their daily lives or their employment producing or evaluating definitions of terms. It can be consulted rather than being read through. The book’s theoretical framework is a distinction, due to Robert H. Ennis, of three dimensions of definitions: the act of (...) the definer, the content of the definition, and its form. The act of a definer is what the definer does in defining a term; the book distinguishes, following Ennis, three basic acts of defining: reporting, stipulating, and advocating. The content of a definition is in one sense the information that the definition conveys and in another sense the words in its defining part. The form of a definition is the way it is expressed, for example as a definition by genus and differentia. (shrink)

Much of the philosophical literature on causation has focused on the concept of actual causation, sometimes called token causation. In particular, it is this notion of actual causation that many philosophical theories of causation have attempted to capture.2 In this paper, we address the question: what purpose does this concept serve? As we shall see in the next section, one does not need this concept for purposes of prediction or rational deliberation. What then could the purpose be? We will argue (...) that one can gain an important clue here by looking at the ways in which causal judgments are shaped by people‘s understanding of norms. (shrink)

The processes of producing scientific knowledge rely on the temporality of data, yet they also obscure this relationship. Scientists hope that knowledge claims can stand relatively independent from their context of production. Instead, a more realistic and trustworthy view would be to embrace data’s history and “journey” (Leonelli and Tempini 2020) as a component of the knowledge claims that these data inspire. These journeys describe how data and people interact and thereby influence each other’s identity and epistemic worth. In this (...) paper, I propose a model to help philosophers and other analysts pay closer attention to the people who work with scientific data, specifically by considering how these practitioners conceptualize time. I argue that how practitioners experience time reflects the personal, professional, epistemic, and ethical values that guide their decisions about how to do science. These conceptions of time differ by profession, career stage, identity, institutional context, and other factors specific to practitioners’ lives as well as their scientific or disciplinary culture. I draw from two case studies of vertebrate fossils to illustrate how various conceptions of time co-exist for practitioners, as indicators of the values that guide practitioners’ decisions as they do scientific work.

New technologies can upset scientific workplaces’ established practices and social order. Scientists may therefore prefer preserving skilled manual work and the social status quo to revolutionary technological change. For example, digital imaging of rock-encased fossils is a valuable way for scientists to “see” a specimen without traditional rock removal. However, interviews in vertebrate paleontology laboratories reveal workers’ skepticism toward computed tomography imaging. Scientists criticize replacing physical fossils with digital images because, they say, images are more subjective than the “real thing.” (...) I argue that these scientists are also implicitly supporting rock-removal technicians, who are skilled and trusted experts whose work would be made obsolete by widespread implementation of CT scanning. Scientists’ view of CT as a sometimes useful tool rather than a universal new approach to accessing fossils preserves the laboratory community’s social structure. Specifically, by privileging “real” specimens and trusted specimen-processing technicians over images and imaging experts, scientists preserve the lab community’s division of labor and skill, hierarchy between scientists and technicians, and these groups’ identity and mutual trust.

This book brings together in one place David Hitchcock’s most significant published articles on reasoning and argument. In seven new chapters he updates his thinking in the light of subsequent scholarship. Collectively, the papers articulate a distinctive position in the philosophy of argumentation. Among other things, the author:• develops an account of “material consequence” that permits evaluation of inferences without problematic postulation of unstated premises.• updates his recursive definition of argument that accommodates chaining and embedding of arguments and allows (...) any type of illocutionary act to be a conclusion. • advances a general theory of relevance.• provides comprehensive frameworks for evaluating inferences in reasoning by analogy, means-end reasoning, and appeals to considerations or criteria.• argues that none of the forms of arguing ad hominem is a fallacy.• describes proven methods of teaching critical thinking effectively.

This paper defines and analyzes the processes of “othering” as they manifest in the practice and praxis of nursing education. Othering is bound up in the establishment and reinforcement of norms, and shores up power inequities that negatively impact faculty, students, and patients. While previous analyses have addressed othering in nursing more broadly, this paper adds a consideration of the multiple processes of othering that operate within the context of nursing education spaces. Cases from recent nursing education literature are interpreted (...) through the frameworks of exclusionary, inclusionary, and structural othering, and provide specific illustrations of the concepts described. The paper concludes by arguing for an application of norm‐critical pedagogical practice to counteract, disrupt and dismantle othering processes within nursing education. (shrink)

A research community must share assumptions, such as about accepted knowledge, appropriate research practices, and good evidence. However, community members also hold some divergent assumptions, which they—and we, as analysts of science—tend to overlook. Communities with different assumed values, knowledge, and goals must negotiate to achieve compromises that make their conflicting goals complementary. This negotiation guards against the extremes of each group’s desired outcomes, which, if achieved, would make other groups’ goals impossible. I argue that this diversity, as a form (...) of value pluralism, regularly influences scientific practice and can make scientific evidence and knowledge more useful and more reliable. As an example, I examine vertebrate paleontology laboratories, which house a variety of workers with different training and priorities, particularly about the meaning of time. Specifically, scientists want to study fully prepared fossils immediately, conservators want to preserve fossils for future use, and preparators mediate between the other groups’ conflicting goals. After all, one cannot study a fossil encased in rock, and one cannot remove that rock without removing information from that specimen. In response, these coworkers articulate their assumptions in everyday deliberations about how scientific evidence should be made and used. I argue that this exchange of assumptions is crucial for a research community to achieve mutually beneficial compromises that benefit current and future knowledge construction. (shrink)

In this paper, Caitlin Murphy Brust and Hannah Widmaier begin with the assumption that highly selective institutions of higher education in the United States have a duty to promote civic equality. They employ Wendy Salkin's theory of informal political representation to examine how highly selective institutions should go about promoting civic equality. According to Salkin's theory, someone serves as an informal political representative (IPR) when they speak or act on behalf of others, without having been selected to do so (...) via a systematized selection procedure. Brust and Widmaier argue that as part of their civic educational missions, highly selective institutions should educate their students for informal political representation, and this includes equipping students to (1) serve as effective IPRs, (2) be responsible audience members to others' informal political representation, and (3) deliberate carefully and with open-mindedness about when they should or should not take on the role of IPR. Brust and Widmaier examine two types of injustice that students from marginalized communities face at highly selective institutions, and they explore how education for informal political representation might ameliorate those injustices. The authors conclude by offering some practical suggestions to institutional policymakers and educators. (shrink)

Background Over the last decade, the return of results (ROR) in precision medicine research (PMR) has become increasingly routine. Calls for individual rights to research results have extended the “duty to report” from clinically useful genetic information to traits and ancestry results. ROR has thus been reframed as inherently beneficial to research participants, without a needed focus on who benefits and how. This paper addresses this gap, particularly in the context of PMR aimed at increasing participant diversity, by providing investigator (...) and researcher perspectives on and questions about the assumed value of ROR in PMR.Methods Semi-structured interviews with a purposive sample of investigators and researchers across federally funded PMR studies in three national consortia, as well as observations of study activities, focused on how PM researchers conceptualize diversity and implement inclusive practices across research stages, including navigating ROR.Results Interviewees (1) validated the value of ROR as a benefit of PMR, while others (2) questioned the benefit of clinically actionable results to individuals in the absence of sufficient resources for translating findings into health care for diverse and disadvantaged populations; (3) expressed uncertainties in applying the presumed value of ROR as a benefit for non-clinical results; and (4) and debated when the promise of the value of ROR may undermine trust in PMR, and divert efforts to return value beyond ROR.Conclusions Conceptualizations of diversity and inclusion among PM researchers and investigators raise unique ethical questions where unexamined assumptions of the value of ROR inform study recruitment efforts to enroll minoritized and under-represented populations. A lack of consideration for resources and infrastructure necessary to translate ROR into actionable information may hinder trustworthy community-research relationships. Thus, we argue for a more intentional interrogation of ROR practices as an offer of benefit and for whom. (shrink)

an observation to formulate a theory, it is no surprise that the resulting theory accurately captures that observation. However, when the theory makes a novel prediction—when it predicts an observation that was not used in its formulation—this seems to provide more substantial confirmation of the theory. This paper presents a new approach to the vexed problem of understanding the epistemic difference between prediction and accommodation. In fact, there are several problems that need to be disentangled; in all of them, the (...) key is the concept of overfitting. We float the hypothesis that accommodation is a defective methodology only when the methods used to accommodate the data fail to guard against the risk of overfitting. We connect our analysis with the proposals that other philosophers have made. We also discuss its bearing on the conflict between instrumentalism and scientific realism.

Following Dretske (1977), there has been a considerable body of literature on the role of contrastive stress in causal claims. Following van Fraassen (1980), there has been a considerable body of literature on the role of contrastive stress in explanations and explanation-requesting why-questions. Amazingly, the two bodies of literature have remained almost entirely disjoint. With an understanding of the contrastive nature of ordinary causal claims, and of the linguistic roles of contrastive stress, it is possible to provide a unified account (...) of both phenomena. I provide such an account from within the framework of a probabilistic theory of causation. Relations of screening-off, long familiar to researchers in probabilistic causality, play a central role in this account. (shrink)

A major challenge in neuroscience is to understand what happens to a brain as it ages. Such insights could make it possible to distinguish between individuals who will undergo typical aging and those at risk for neurodegenerative disease. Over the last quarter century, thousands of human brain imaging studies have probed the neural basis of age-related cognitive decline. “Aging” studies generally enroll adults over the age of 65, a historical precedent rooted in the average retirement age of U.S. wage-earners. A (...) consequence of this research tradition is that it overlooks one of the most significant neuroendocrine changes in a woman’s life: the transition to menopause. The menopausal transition is marked by an overall decline in ovarian sex steroid production – up to 90% in the case of estradiol – a dramatic endocrine change that impacts multiple biological systems, including the brain. Despite sex differences in the risk for dementia, the influence that biological sex and sex hormones have on the aging brain is historically understudied, leaving a critical gap in our understanding of the aging process. In this Perspective, we highlight the influence that endocrine factors have on the aging brain. We devote particular attention to the neural and cognitive changes that unfold in the middle decade of life, as a function of reproductive aging. Next, we consider emerging evidence from animal and human studies that other endocrine factors occurring earlier in life (e.g. pregnancy, hormonal birth control use) also shape the aging process.

One of the motivations for Salmon's (1984) causal theory of explanation was the explanatory irrelevance exhibited by many arguments conforming to Hempel's covering-law models of explanation. However, the nexus of causal processes and interactions characterized by Salmon is not rich enough to supply the necessary conception of explanatory relevance. Salmon's (1994) revised theory, which is briefly criticized on independent grounds, fares no better. There is some possibility that the two-tiered structure of explanation described by Salmon (1984) may be pressed into (...) service, but more work would have to be done. Ironically, Salmon's difficulties are similar to those suffered by his seventeenth-century predecessors. (shrink)

How do children acquire beliefs from testimony? In this chapter, we discuss children's trust in testimony, their sensitivity to and use of defeaters, and their appeals to positive reasons for trusting what other people tell them. Empirical evidence shows that, from an early age, children have a tendency to trust testimony. However, this tendency to trust is accompanied by sensitivity to cues that suggest unreliability, including inaccuracy of the message and characteristics of the speaker. Not only are children sensitive to (...) evidence of unreliability, but they are also sensitive to the positive reasons a speaker may have for the reliability of their testimony. This evidence is discussed in relation to reductivist and non-reductivist viewpoints. (shrink)

There are many ways of attaching two objects together: for example, they can be connected, linked, tied or bound together; and the connection, link, tie or bind can be made of chain, rope, or cement. Every one of these binding methods has been used as a metaphor for causation. What is the real significance of these metaphors? They express a commitment to a certain way of thinking about causation, summarized in the following thesis: ‘In any concrete situation, there is an (...) objective fact of the matter as to whether two events are in fact bound by the causal relation. It is the aim of philosophical inquiry to analyze this objective relation.’ Through a variety of examples, I hope to cast doubt on this seemingly innocuous thesis. The problem lies not with the word ‘objective’, but with the word ‘the’.

Background Nigeria is an emerging hub of biomedical research, requiring additional trained bioethicists for ethical oversight of research studies. There are currently two graduate-level health research ethics programs in Nigeria. However, both are in the southern part of the country and no such training programs exist in the north. Strengthening the health research ethics skills and knowledge of Nigerian researchers across the country is necessary given the growing genetics research infrastructure. Methods To inform the creation of a Master of Science (...) in Health Research Ethics program in northern Nigeria, we conducted a needs assessment comprised of semi-structured interviews with nine Nigerian bioethics experts. We used the Interpretative Phenomenological Analysis (IPA) method to analyze interview transcriptions. Two authors independently read and coded each respondent’s transcript to identify emergent themes that represented each respondent’s answers. Within these overarching themes, the data points were grouped into subthemes. Results Four primary themes emerged with ten subthemes. Respondents believed that the program can fill a gap and strengthen capacity in health research ethics. They emphasized that the curriculum should be developed with an interdisciplinary lens and locally contextualized, and that students should be taught how to think critically through ethical scenarios. Respondents stressed that program leaders should recruit faculty and students locally who have the bandwidth to participate in the program. Finally, respondents noted the program should have university support to be sustainable. Conclusion Our findings will guide the creation of a master’s degree program that aims to build capacity in health research ethics in northern Nigeria and enhance the country’s growing prominence in global biomedical research. Through our needs assessment, we identified structural and content factors that can guide us in leveraging the strengths of the local institution and leaders in health research ethics while mitigating challenges in establishing this program.

The purpose of this paper is to examine the linkages and relationships between the officially prescribed school ethos and that which emerges from social interaction. Qualitative data drawn from one Grant-Maintained-Integrated and one Catholic primary school in Northern Ireland show how school ethos, defined as the observed practices and interactions of school members, often departs considerably from school ethos defined as those values and beliefs which the school officially supports. On the basis of the data it is argued that much (...) of what we understand of school ethos is superficial and contradictory.

Drawing on Donna Haraway’s cyborg theory and Black feminist thought, the part-time cyborg reclaims rest and refusal as strategies for survival and defiance. The article argues that mundane authoritarianism operates through small, everyday demands that normalize compliance, particularly for Black women, whose bodies have long been sites of scrutiny and control. By turning off (...) a camera or withdrawing from hypervisibility, the part-time cyborg disrupts these systems, asserting autonomy in the face of extractive logics.

“Probabilistic Causation” designates a group of theories that aim to characterize the relationship between cause and effect using the tools of probability theory.

A variety of issues within, and objections to, probabilistic theories of causation will also be discussed.

The amygdala is a key brain area regulating responses to stress and emotional stimuli, so improving our understanding of how it is regulated could offer novel strategies for treating disturbances in emotion regulation.

In addition, it appears that the microbiota is necessary for normal development of (...) the amygdala at both the structural and functional levels. While further investigations are needed to elucidate the exact mechanisms of microbiota-to-amygdala communication, ultimately, this work raises the intriguing possibility that the gut microbiota may become a viable treatment target in disorders associated with amygdala dysregulation, including visceral pain, post-traumatic stress disorder, and beyond. Also see the video abstract here: https://youtu.be/O5gvxVJjX18 The amygdala plays a central role in regulating many aspects of behavior in rodents and humans, from pain responding to social interaction and psychiatric function.

The disciplines of ethics, science, and the law often conflict when it comes to determining the limits and boundaries of embryo research. Under current Australian law and regulations, and in various other jurisdictions, research conducted on the embryo in vitro is permitted up until day fourteen, after which, the embryo must be destroyed.

It it tempting to think that if an outcome had some probability of not occurring, then we cannot explain why that outcome in fact occurred. Despite this intuition, most philosophers of science have come to admit the possibility of indeterministic explanation.

I argue that this is an untenable compromise: if indeterministic explanation is possible, then (...) indeterministic contrastive explanation is possible too.

I advance a new theory of causal relevance, according to which causal claims convey information about conditional probability functions. This theory is motivated by the problem of disjunctive factors, which haunts existing probabilistic theories of causation. After some introductory remarks, I present in Section 3 a sketch of Eells's (1991) probabilistic theory of causation, which provides the framework for much of the discussion. Section 4 explains how the problem of disjunctive factors arises within this framework. After rejecting three proposed solutions, (...) I offer in Section 6 a new approach to causation that avoids the problem. Decision-theoretic considerations also support the new approach.

In many actual arguments, the conclusion seems intuitively to follow from the premisses, even though we cannot show that it follows logically. The traditional approach to evaluating such arguments is to suppose that they have an unstated premiss whose explicit addition will produce an argument where the conclusion does follow logically. But there are good reasons for doubting that people so frequently leave the premisses of their arguments unstated. The inclination to suppose that they do stems from the belief that (...) the only way in which an argument's conclusion can follow definitely from its premisses is to follow logically. I argue that this belief is mistaken. I propose a revision of the current generic conception of logical consequence, and its variant specifications, to avoid the paradoxes of strict implication. The revised conception can then be naturally extended to include also what we might call 'enthymematic consequence'. This concept is a kind of consequence, whose properties merit investigation.

BackgroundReturning neuroimaging incidental findings may create a challenge to research participants’ health literacy skills as they must interpret and make appropriate healthcare decisions based on complex radiology jargon. Disclosing IF can therefore present difficulties for participants, research institutions and the healthcare system. The purpose of this study was to identify the extent of the health literacy challenges encountered when returning neuroimaging IF. We report on findings from a retrospective survey and focus group sessions with major stakeholders involved in disclosing IF.MethodsWe (...) surveyed participants who had received a radiology report from a research study and conducted focus groups with participants, parents of child participants, Institutional Review Board members, investigators and physicians. Qualitative thematic analyses were conducted using standard group-coding procedures and descriptive summaries of health literacy scores and radiology report outcomes are examined.ResultsAlthough participants reported high health literacy skills, 67 % did not seek medical care when recommended to do so; and many participants in the focus groups disclosed they could not understand the findings described in their report. Despite their lack of understanding, participants desire to have information about their radiology results, and the investigators feel ethically inclined to return findings.ConclusionsThe language in clinically useful radiology reports can create a challenge for participants’ health literacy skills and has the potential to negatively impact the healthcare system and investigators conducting imaging research. Radiology reports need accompanying resources that explain findings in lay language, which can help reduce the challenge caused by the need to communicate incidental findings. (shrink)
