In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

Abstract‘The Future of Legal Gender’ project has assessed the potential implications for feminist legal scholarship and activism of decertifying sex/gender. Decertification refers to the state moving away from officially determining or registering sex/gender. This article explores the potential impact of such moves on equal pay law and gender pay gap reporting. Equal pay and gender pay gap reporting laws provide an important focus for the project because they aim to address structural dynamics associated with persistent pay inequality that women experience (...) across occupations in the United Kingdom. These legal measures illuminate gendering as a large-scale social problem widely understood to operate structurally and systemically. What effect, then, could decertifying sex/gender have on the law and conceptual power of equal pay? Might decertification undermine the structure of equal pay law, with all hard-won gains it has brought for women? Or is it possible to imagine that decertification could accompany a more inclusive and effective legal architecture for equal pay? (shrink)

Physicists are increasingly beginning to take seriously the possibility of laws outside the traditional time-evolution paradigm; yet many popular definitions of determinism are still predicated on a time-evolution picture, making them manifestly unsuited to the diverse range of research programmes in modern physics. In this article, we use a constraint-based framework to set out a generalization of determinism which does not presuppose temporal evolution, distinguishing between strong, weak and delocalised holistic determinism. We discuss some interesting consequences of these generalized notions (...) of determinism, and we show that this approach sheds new light on the long-standing debate surrounding the nature of objective chance.

This book draws its inspiration from Hilbert, Wittgenstein, Cavaillès and Lakatos and is designed to reconfigure contemporary philosophy of mathematics by making the growth of knowledge rather than its foundations central to the study of mathematical rationality, and by analyzing the notion of growth in historical as well as logical terms. Not a mere compendium of opinions, it is organised in dialogical forms, with each philosophical thesis answered by one or more historical case studies designed to support, complicate or question (...) it. The first part of the book examines the role of scientific theory and empirical fact in the growth of mathematical knowledge. The second examines the role of abstraction, analysis and axiomatization. The third raises the question of whether the growth of mathematical knowledge constitutes progress, and how progress may be understood. Readership: Students and scholars concerned with the history and philosophy of mathematics and the formal sciences. (shrink)

Canada’s Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans mandates that all research involving human subjects be reviewed and approved by a research ethics board . We have little evidence on how researchers are dealing with this requirement in multisite studies, which involve more than one REB. We retrospectively examined 22 REB submissions for two minimal-risk, multisite studies in leading Canadian institutions. Most REBs granted expedited review to the studies, while one declared the application to be exempt from review. (...) Time between submission and approval ranged greatly, from four to 546 days. We received a total of 155 REB queries for changes and clarifications, most of which asked for further information, clarification, or additional documents. Less than a third of the REB queries were requests for specific changes, and a vast majority had a very limited impact on the research projects. Institutions also varied broadly in their description of what was required of local principal investigators. We conclude that the organizational and practical challenges these results imply could deter researchers from embarking on multisite research projects, and that recently proposed changes to the TCPS will not solve these problems.

There is little agreement about Aristotle’s philosophy of geometry, partly due to the textual evidence and partly part to disagreement over what constitutes a plausible view. I keep separate the questions ‘What is Aristotle’s philosophy of geometry?’ and ‘Is Aristotle right?’, and consider the textual evidence in the context of Greek geometrical practice, and show that, for Aristotle, plane geometry is about properties of certain sensible objects—specifically, dimensional continuity—and certain properties possessed by actual and potential compass-and-straightedge drawings qua quantitative and (...) continuous. For their part, the objects of stereometry are potential sensible three-dimensional figures qua quantitative and continuous. (shrink)

Abstract:Vulnerability is an important criterion to assess the ethical justification of the inclusion of participants in research trials. Currently, vulnerability is often understood as an attribute inherent to a participant by nature of a diagnosed condition. Accordingly, a common ethical concern relates to the participant’s decisionmaking capacity and ability to provide free and informed consent. We propose an expanded view of vulnerability that moves beyond a focus on consent and the intrinsic attributes of participants. We offer specific suggestions for how (...) relational aspects and the dynamic features of vulnerability could be more fully captured in current discussions and research practices. (shrink)

Emerging demonstrations of the malleability of distance perception in affective situations require an organizing structure. These effects can be predicted by approach and avoidance orientation. Approach reduces perceptions of distance; avoidance exaggerates perceptions of distance. Moreover, hedonic valence, motivational intensity, and perceiver arousal cannot alone serve as organizing principles. Organizing the literature based on approach and avoidance can reconcile seeming inconsistent effects in the literature, and offers these motives as psychological mechanisms by which affective situations predict perceptions of distance. Moreover, (...) this perspective complements functional models of perception claiming perceptions of distance serve adaptive responding, and in so doing suggests why perceptions of distance respond to affective situations. This review contributes to the building of a broader theory of motivated distance perception. (shrink)

With the normative demand to attend to social difference and an absence of universal evaluative terms with which to do so, recent theory has increasingly turned to the study of the affective rather than epistemological conditions of ethical encounter. This I call a “dispositional ethics” that construes responsibility as responsiveness. Recent articulations of such an ethics, notably in the most current work of Judith Butler, James Tully, Jade Larissa Schiff, and Ella Myers, highlight its connection to situated practices of concrete (...) bodies-in-relation, but often stop short of developing an account of what such embodied practices might be. Based on interviews with thirteen experts who take the body as their primary vocational and intellectual field and characterize their practice as an art of listening, I distinguish three dimensions of a dispositional ethics in practice and some of the specific strategies available to cultivate the conditions for responsiveness in political life.

In this article we report relevant data that shed light on the topic of hope and patients’ expectations in the use of DBS, for standard, approved, and established indications, based on a broader qualitative study on the ethical and social challenges that healthcare providers face in the field of DBS.

I assess various proposals for the source of the intuition that there is something problematic about contextuality, ultimately concluding that contextuality is best thought of in terms of fine-tuning. I then argue that as with other fine-tuning problems in quantum mechanics, this behaviour can be understood as a manifestation of teleological features of physics. Finally I discuss several formal mathematical frameworks that have been used to analyse contextuality and consider how their results should be interpreted by scientific realists. In the (...) course of this discussion I obtain several new mathematical results—I demonstrate that preparation contextuality is a form of fine-tuning, I show that measurement contextuality can be explained by appeal to a global constraint forbidding closed causal loops, and I demonstrate how negative probabilities can arise from a classical ontological model together with an epistemic restriction.

Everyday ethics refers to those issues which have a sometimes unrecognized moral dimension and that arise regularly within healthcare and research. These issues are often contrasted to dramatic ethics issues (i.e. issues that have seemingly higher stakes such as those arising in acute care situations or with invasive or life-threatening interventions). Claims have been made that scholarly bioethics tends to focus on dramatic ethics to the detriment of everyday ethics discussions. However, empirical evidence showing this has been lacking. Our own (...) research investigating bioethics discussions in the Parkinson’s disease literature suggested this trend. Consequently, we decided to characterize the context and content of the Parkinson’s disease bioethics literature to empirically test the hypothesis that everyday ethics is under discussed. We conducted a broad literature search using the keywords “Parkinson’s disease” AND (“ethics” OR “bioethics”) and classified results inductively based on the context in which the bioethics discussion occurred. In line with our hypothesis and initial observations, we found that there is indeed a greater focus on dramatic ethics where topics such as deep brain stimulation and neuronal cell transplantations, dominated bioethics discussions. Given the potential utility of everyday ethics in improving healthcare and research, this mismatch in focus ought to be addressed. There is a clear need for further understanding and discussion of everyday ethical issues in scholarly bioethics. (shrink)

Over the course of human life, health care decision‐making is often interdependent. In this article, we use “interdependence” to refer to patients’ engagement of nonclinicians—for example, family members or trusted friends—to reach health care decisions. Interdependence, we suggest, is common for patients in all stages of life, from early childhood to late adulthood. This view contrasts with the common bioethical assumption that medical decisions are either wholly independent or dependent and that independence or dependence is tightly coupled with a person's (...) decision‐making capacity. In this article, we array various approaches to decision‐making along a continuum of interdependence. An appreciation of this continuum can empower patients and elucidate ethical challenges that arise when people transition between different kinds of interdependence across the life span. (shrink)

Decolonization requires critical attention to settler logics that reinforce settler-colonialism, yet settler communities, as a rule, operate without a collective sense of identity and history. This article, provoked by Māori protocols of encounter, explores the necessity of developing a sense of collective identity as precursor to meeting in settler-Indigenous politics. It argues that the ability, desire, and experience of being unmarked as a social group—apparent in paradigmatic approaches to engaging social difference in settler communities—is at the heart of the particularity (...) of settler group identity and also stands at the heart of countless failures to meet in settler-Indigenous politics. This essay thus seeks to mark the particular ground of this unmarkedness of settler identity in Western philosophies that set being unmarked as both ontology and ideal; the dominance of settler communities in places of settlement; and the willful forgetting of the colonial histories brought about by such dominance.

In the article “Nudging and Informed Consent”, Cohen argues that the use of “nudging” by physicians in the clinical encounter may be ethically warranted because it results in an informed consent where obligations for beneficence and respect for autonomy are both met. However, the author's overenthusiastic support for nudging and his quick dismissal of shared decision-making leads him to assume that “soft” manipulation is un-problematic and that “wisdom” on the side of medical professionals will suffice to guard against abuse. Opposing (...) this view, we propose that: 1) patient preferences and values should not be boiled down to rational or irrational decisions based on cognitive reasoning alone, 2) potential threats to the physician-patient must be mitigated and could be minimized by employing alternative strategies that acknowledge the impact of cognitive heuristics in shaping decision-making but maintain transparency and trust, and 3) patient preferences and values can be legitimately influenced only under specific circumstances. The latter include: (1) exhaustion of other means; (2) evidence that nudging is effective in a specific context; (3) evidence of clear and active public misinformation (e.g., industry promoting smoking); (4) explicit pubic dialogue between various stakeholders including medical professional societies about nudging; (5) upholding shared decision-making as a preferred approach; and (6) a rich understanding of clinical reality beyond the simple dichotomy of beneficence-autonomy.

This book deals with a topic that has been largely neglected by philosophers of science to date: the ability to refer and analyze in tandem. On the basis of a set of philosophical case studies involving both problems in number theory and issues concerning time and cosmology from the era of Galileo, Newton and Leibniz up through the present day, the author argues that scientific knowledge is a combination of accurate reference and analytical interpretation. In order to think well, we (...) must be able to refer successfully, so that we can show publicly and clearly what we are talking about. And we must be able to analyze well, that is, to discover productive and explanatory conditions of intelligibility for the things we are thinking about. The book’s central claim is that the kinds of representations that make successful reference possible and those that make successful analysis possible are not the same, so that significant scientific and mathematical work typically proceeds by means of a heterogeneous discourse that juxtaposes and often superimposes a variety of kinds of representation, including formal and natural languages as well as more iconic modes. It demonstrates the virtues and necessity of heterogeneity in historically central reasoning, thus filling an important gap in the literature and fostering a new, timely discussion on the epistemology of science and mathematics.

Just as the nation is imagined and produced through everyday rhetoric and maps and flags, it is also constructed on the skin, and through bodies, by different types of corporeal `flagging'. In this article, I use two examples of contemporary surgical procedures to explore these dynamics. Aesthetic surgeries on `white' subjects are not often interrogated for their racializing effects, but I use the concept of `flagging' to explore how these surgeries work in the UK to align `white' bodies with a (...) white nation. US media coverage of Iraq invasion veterans with prosthetic limbs circulates narratives of heroism and patriotism, and I explore how the apparent `visibility' of these limbs works to re-embed notions of the US as a transcendent Christian nation. In these two examples of corporeal modification, the nation is `flagged' on the skin, reiterating relationships of belonging that echo practical and conceptual links with property. Propertied belonging — possessive and constitutive — unfolds through bodies, producing whiteness not only as property itself, but also as unmarked, habitual terrain. (shrink)

Some fictions seem to involve branching time, where one time series ‘splits’ into two or two time series ‘fuse’ into one. We provide a new framework for thinking about these fictional representations: not as representations of branching time series but rather as branching representations of linear time series. We explain how branching at the level of the representation creates a false impression that the story describes a branching of the time series in the fictional world itself. This involves explaining away (...) the illusion of various causal connections which may at first appear essential to understanding the story as a unified whole. This provides a more accurate account of the relationship between the representation and what is represented, which in turn reveals the extent to which it is legitimate to draw conclusions about actual time from fictional representations.

Empirical psychology documents widespread evidence of bias in the ways that people select, interpret, and selectively interpret evidence in forming and revising their beliefs. These biases can function to create and perpetuate epistemologies of ignorance. I argue that virtue epistemology can help us explain what goes epistemically wrong in these cases, and can offer positive advice, orienting us toward ways to right it. In particular, I defend the virtue approach from epistemic situationist worries about the empirical plausibility of individual agents' (...) ability to develop corrective virtues. I argue that situational virtues are genuine responsibilist virtues, and are one of the tools at our disposal for overcoming epistemologies of ignorance. (shrink)

Lower respiratory tract infections are a leading cause of paediatric morbidity and mortality worldwide. Children in low-income countries are disproportionately affected. This is in large part due to limitations in healthcare resources and medical technologies. Mechanical ventilation can be a life-saving therapy for many children with acute respiratory failure. The scarcity of functioning ventilators in low-income countries results in countless preventable deaths. Some hospitals have attempted to adapt to this scarcity by using hand-bag ventilation, as either a bridge to a (...) mechanical ventilator, or until clinical improvement occurs rendering mechanical ventilation no longer necessary. In instances of hand-bag ventilation, an endotracheal tube is first placed. Family members are then asked to play the role of a ventilator, manually compressing a bag repeatedly to inflate the child’s lungs. This approach is fraught with numerous ethical challenges. A careful examination of the data and a nuanced approach to the ethical considerations are imperative. Ethical arguments in support of and in opposition to allowing parental hand-bag ventilation are explored, including the best interests of the child, the child’s right to an open future, beneficence and parental protection, legitimising substandard care, and finally, contextual concerns. An algorithmic, potentially ethically permissible approach to parental participation in manual ventilation is proposed. (shrink)

With so much attention on the issue of voice in democratic theory, the inverse question of how people come to listen remains a marginal one. Recent scholarship in affect and neuroscience reveals that cognitive and verbal strategies, while privileged in democratic politics, are often insufficient to cultivate the receptivity that constitutes the most basic premise of democratic encounters. This article draws on this scholarship and a recent case of forum theatre to examine the conditions of receptivity and responsiveness, and identify (...) specific strategies that foster such conditions. It argues that the forms of encounter most effective in cultivating receptivity are those that move us via affective intensity within pointedly mediated contexts. It is this constellation of strategies—this strange marriage of immersion and mediation—that enabled this performance to surface latent memory, affect and bias, unsettle entrenched patterns of thought and behaviour, and provide the conditions for revisability. This case makes clear that to lie beyond the domain of cognitive and verbal processes is not to lie beyond potential intervention, and offers insight to how such receptivity might be achieved in political processes more broadly.

Most discussions of Leibniz's metaphysics of time and space begin and end with the correspondence between Leibniz and Samuel Clarke, Newton's friend and defender. But Leibniz's ideas about time and space are far richer than this exchange suggests, and Michael Futch shows that the study of those investigations will enhance current discussion among philosophers and cosmologists. Futch's scholarly attention to a wide range of texts is matched by his philosophical acuity. His detailed expositions of texts are not tedious or pedantic (...) because he never fails to bring out their philosophical interest and pertinence. So, too, the book's bibliography is especially valuable.The book opens with a discussion of Newton's substantivalism, which treats time and space as substance-like structures that exist independent of the objects located in them, versus Leibniz's reductionism, which holds time and space to be merely relations, ontologically dependent on the things that exist: space is the order of coexistences, time the order of successions. Futch gives useful historical background that explains why the debate takes the form that it does and what. (shrink)

Surgeries inevitably raise questions of bodily integrity: how the post-surgical body reframes (or does not reframe) its experiences of functionality to incorporate new features. Nevertheless, when we try to define or delimit the concept of bodily integrity, it becomes increasingly important to think about how the physical and social unease caused by some forms of surgeries sits alongside the more transformative potential of surgical bodily modification. This article focuses on aesthetic genital surgeries on infants with disorders of sex development (DSD, (...) previously termed ‘intersex’ conditions). Using the work of Pierre Bourdieu and Elizabeth Freeman on time, bodies and ‘chrononormativity’, this article excavates not only the temporalities that produce what I would term ‘chrono-abnormalities’ of sex development, but also the temporalized medical responses, including surgeries, which retrieve ‘abnormal’ bodies into more normative time-lines. My conclusion is that when DSD-affected individuals experience aesthetic genital surgeries as painful and full of social unease this is not necessarily because the pre-surgical body was the ‘natural’, ‘whole’ or ‘intact’ body prior to surgery. Instead, it is because these surgeries interrupt what Bourdieu would term a sense of corporeal ‘immersion into the forthcoming’; an immersion which, in his theory of time as social action, is intimately linked with social power and possibilities.

The authors conducted a qualitative analysis of thirty-seven issues of The DDU Review, a newsletter produced by residents of the Dual Diagnosis Unit, a residential unit for people who had diagnoses of developmental disability and serious mental illness in the Central State Hospital. The analysis of the newsletters produced between September 1988 and June 1992 revealed three major themes: 1) the mundane; 2) good behavior; and 3) advocacy. Contrary to the authors’ expectations, the discourse of medicalization—such as relations with physicians, (...) diagnoses, and medications—receive little attention. Instead, the patient-journalists focus on prosaic aspects of institutional life. The patients used their writing as a form self-definition and advocacy. The authors argue that even though it is tempting to consider the patients’ emphasis on good behavior as evidence of institutional control, internalized discipline, and medicalization, a more nuanced interpretation, which focuses on how the patients’ understood their own experiences, is warranted. Researchers must also recognize the ways in which The DDU Review reveals the patient-journalists’ experience of an institutional life that includes non-medical staff, varied social relationships among patients, and negotiated freedoms.

Tree-chopping in the Aeneid has long been seen as a disturbingly violent symbol of the Trojans' colonization of Italy. The paper proposes a new reading of the poem which sees Aeneas as progressive extirpator not just of foreign rivals but also of his own Trojan relatives. Although the Romans had no family “trees” as such, their genealogical stemmata (“garlands”) had “branches” (rami) and “stock” (stirps), and their vocabulary of family relationships takes many of its metaphors from planting, adoption, and uprooting, (...) while plant life is often described in human metaphors. Imperial historians use the growth and collapse of trees to mark the rise and fall of dynasties; natural historians like Columella and Pliny use metaphors of adoption, abortion, and adultery to characterize the perversions of agriculture and horticulture. It is thus no coincidence that Aeneas' encounters with Hector, Priam, Deiphobus, and others often take place against a background of real or metaphorical trees (tree similes, headless or mutilated human trunks, ancient trees and woods). These encourage us to see an element of dynastic encroachment in scenes that look pious and peaceable but confirm Aeneas' ascendancy and claim to Trojan succession. The Polydorus episode in particular can be read not just as a grotesque interlude but as a nightmare about endlessly reproducing heirs; one loose strand from Priam's house is allowed to remain, while Virgil deals imperfectly with the problem of Aeneas' own successors. The paper ends by re-examining Virgil's account of grafting in Georgics 2 and arguing that it is viewed positively, perhaps in order to cast Augustus' adoption of heirs as a miracle solution.

This article draws on in-depth interviews with nine white, middle-class, male-to-female transsexuals to examine how they produce and experience bodily transformation. Interviewees’ bodywork entailed retraining, redecorating, and reshaping the physical body, which shaped their feelings, role-taking, and self-monitoring. These analyses make three contributions: They offer support for a perspective that embodies gender, further transsexual scholarship, and contribute to feminist debate over the sex/gender distinction. The authors conclude by exploring how viewing gender as embodied could influence medical discourse on transsexualism and (...) have personal and political consequences for transsexuals. (shrink)

Birdsong is widely analysed and discussed by people coming from both musical and scientific backgrounds. Both approaches provide valuable insight, but I argue that it is only through combining musical and scientific points of view, as well as perspectives from more tangentially related fields, that we can obtain the best possible understanding of birdsong. In this paper, I discuss how my own training as a musician, and in particular as a composer, affects how I listen to and parse birdsong. I (...) identify nine areas of overlap between human music and birdsong, which may serve as starting points both for musical and scientific analysis, as well as for interdisciplinary analysis as practiced in the developing field of “zoomusicology.” Using the hermit thrush (Catharus guttatus) as an example, I discuss how the song of a single species has been described by writers from a variety of disciplines, including music, literature, and the sciences, as well as how we can contextualise these varied perspectives in terms of broader cultural thought trends. I end with discussion of how combining approaches from multiple fields can help us to figure out new questions to ask, can help us identify how our own cultural biases may affect how we hear birdsong, and ultimately can help us develop richer and more nuanced understandings of the songs themselves.

Contemporary hormonal therapy for the menopause has its conceptual origins in the ancient tradition of organotherapy. The popular but pharmacologically inactive precursors of hormonal therapy were developed as part of a resurgence of interest in organotherapy in the 19th century, which coincided with increasing medicalization of the menopause and the view that the ovaries were responsible for the ‘feminine’ identity and wellbeing of women. The subsequent chemical identification of oestrogens allowed the development of pharmacologically active hormonal therapy for the menopause, (...) which was probably first used clinically in the late 1920s. Around this time, emphasis shifted from the ovaries to oestrogen as being responsible for femininity and health, with the menopause and ageing increasingly defined as oestrogen deficiency diseases. Hormonal therapy for the menopause was first used predominantly for women who had a premature menopause. In the 1960s, universal prescription was increasingly promoted as a way of preventing diseases of later life and the perceived ‘defeminization’ of women by menopause. Scientific evidence regarding the risks and benefits of hormonal therapy for the menopause has been accruing over the last 70 years; its interpretation has been affected by background beliefs regarding the effects of oestrogen and the menopause on women.

The central issues raised in much of feminist literary theory's early scholarship remain prescient: how does narrative engage with the social‐historical? In what ways does it codify existing structures? How does it resist them? Whose stories are not being told, or read? In this article I use Doris Lessing's novel The Fifth Child (1988) as a text with which to begin to address the above questions by reading with attention to the mother story but also the ‘other’ stories operating both (...) within and outside of the novel; in particular I am concerned with the convergence of maternity, disability and narrative. The novel's co-implication of sexual difference and corporeal difference reveals the ways in which the mother's story is both made possible and authorized by the disabled body of her child, and by his inability to tell his own story. Yet, if The Fifth Child is a horror story that uses the disabled child's body as its ground, it is also about the horror of maternity, in its conception and attendant choices. In this fictional story as well as in the social‐historical narrative circulating at the time of its publication in the late 1980s, both child and mother are indicted in their otherness and it is ultimately impossible to separate one from the other.

Lee and Schwarz propose grounded procedures of separation as a domain-general mechanism underlying cleansing effects. One strong test of domain generality is to investigate the ontogenetic origins of a process. Here, we argue that the developmental evidence provides weak support for a domain-general grounded procedures account. Instead, it is likely that distinct separation procedures develop uniquely for different content domains.

In this essay, I consider the use of mathematical statistics in the study of biological systems in the field, using as case studies the work of Ruth Geyer Shaw and her colleagues at the University of Minnesota. To address practical issues, like how to enhance prairie restoration, and how to prepare for (and perhaps prevent) the effect of rapid climate change, she and her colleagues combine mathematical modeling and intensive data collection in the field. Using ANOVA and the more versatile (...) approach of Aster Models, they show the effects of inbreeding (which follows from the fragmentation of prairie) to lower the fitness of plant populations. They study the genetic variance of plants in stable populations, which is important when that population must deal with changing conditions. And they study the consequences of rapid climate change: even good genetic variance and initial fitness may not save a given population from extinction. This leads to a new alliance of science with local, state, federal and global politics. (shrink)

Developmental Coordination Disorder and Attention-Deficit/Hyperactivity Disorder are unique neurodevelopmental disorders with overlaps in executive functions and motor control. The conditions co-occur in up to 50% of cases, raising questions of the pathological mechanisms of DCD versus ADHD. Few studies have examined these overlaps in adults with DCD and/or ADHD. Therefore, to provide insights about executive functions and motor control between adults with DCD, ADHD, both conditions, or typically developed controls, this study used a stop-signal task and parallel EEG measurement. We (...) assessed executive performance via go accuracy and go reaction time, as well as motor response inhibition via stop-signal reaction time. This was complemented with analysis of event-related potentials. Based on existing investigations of adults with DCD or ADHD, we expected groups would not differ in behavioral performance on stop and go trials, but differences in ERPs, particularly in components N200 and P300 would be evident. The sample included N = 50 adults with DCD, ADHD, DCD + ADHD, and control participants. We replicated that there were no between-group differences for behavioral-level executive performance and motor response inhibition. However, on a physiological level, ERP components N200 and P300 differed between groups, particularly during successful response inhibition. These ERPs reflect potential endophenotypic differences not evident in overt behavior of participants with ADHD and/or DCD. This suggests a disorder specific employment of inhibition or general executive functions in groups of adults with DCD, DCD + ADHD, ADHD, or control participants. (shrink)
