We report a novel task designed to elicit transient attention-lapse induced alienation of agency experiences in normal participants. When attention-related action slips occur during the task, participants reported substantially decreased self control as well as a high degree of perceived agency attributed to the errant hand. In addition, participants reported being surprised by, and annoyed with, the actions of the errant hand. We argue that ALIA experiences occur because of constraints imposed by the close and precise temporal relations between intention (...) formation and a contrary action employed in this paradigm. We note similarities between ALIA experiences and anarchic hand sign and argue that, despite important differences, both ALIA experiences and AHS phenomenology reflect failures of executive control to intervene and cancel contrary affordance-driven habitual motor plans.

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability (...) and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values. (shrink)

Previously we reported a three-factor structure for hallucinations accompanying sleep paralysis . These earlier analyses were, however, based on retrospective accounts. In a prospective study, 383 individuals reported individual episodes online providing further evidence for the three-factor structure as well as clearer conceptually meaningful relations among factors than retrospective studies. In addition, reports of individual episodes permitted a more fine-grained analysis of the internal structure of factors to assess predictions based on the hypothesis that a sensed or felt presence is (...) a core experience affecting other SP hallucinations. Results were generally consistent with this hypothesis. In particular, associations among, and temporal stability of, sensory hallucinations were largely explained by their common association with FP. The findings are consistent with REM initiation of a threat activated vigilance system with pervasive effects on the SP experience and suggest a potential model for the thematic organization of nightmares and dreams more generally.

A 'sensed presence' often accompanies hypnagogic and hypnopompic hallucinations associated with sleep paralysis. Qualitative descriptions of the sensed presence during sleep paralysis are consistent with the experience of a monitoring, stalking predator. It is argued that the sensed presence during sleep paralysis arises because of REM-related endogenous activation of a hypervigilant and biased attentive state, the normal function of which is to resolve ambiguities inherent in biologically relevant threat cues. Given the lack of disambiguating environmental cues, however, the feeling of (...) presence persists as a protracted experience that is both numinous and ominous. This experience, in turn, shapes the elaboration and integration of the concurrent hallucinations that often take on supernatural and daemonic qualities. The sense of presence considered here is an 'other' that is radically different from, and hence more than a mere projection of, the self. Such a numinous sense of otherness may constitute a primordial core consciousness of the animate and sentient in the world around us. (shrink)

Nielsen [Nielsen, T. . Felt presence: Paranoid delusion or hallucinatory social imagery? Consciousness and Cognition, 16, 975–983.] raises a number of issues and presents several provocative arguments worthy of discussion regarding the experience of the felt presence during sleep paralysis . We consider these issues beginning with the nature of FP and its relation to affective-motivational systems and provide an alternative to Nielsen’s reduction of FP to a purely spatial hallucination. We then consider implications of the “normal social imagery” model. (...) We can find only one specific empirical hypothesis articulated within this framework and it turns out to be one that we explicitly addressed in our original paper. We also review our position regarding the possible relation of FP during SP to a number of related anomalous experiences and contrast FP to anomalous vestibular-motor phenomena. We review our position that the neuromatrix concept, in the light of available evidence, is more appropriately applied to V-M experiences than FP. Finally, we pursue speculations, raised in Nielsen’s commentary, on the wider implications of FP. (shrink)

In two studies of a GO–NOGO task assessing sustained attention, we examined the effects of altering speed–accuracy trade-offs through instructions and auditory alerts distributed throughout the task. Instructions emphasizing accuracy reduced errors and changed the distribution of GO trial RTs. Additionally, correlations between errors and increasing RTs produced a U-function; excessively fast and slow RTs accounted for much of the variance of errors. Contrary to previous reports, alerts increased errors and RT variability. The results suggest that standard instructions for sustained (...) attention tasks, emphasizing speed and accuracy equally, produce errors arising from attempts to conform to the misleading requirement for speed, which become conflated with attention-lapse produced errors and auditory alerts have complex, and sometimes deleterious, effects on attention. We argue that instructions emphasizing accuracy provide a more precise assessment of attention lapses in sustained attention tasks. (shrink)

Rhythm is the fundamental pulse that animates poetry, music, and dance across all cultures. And yet the recent explosion of scholarly interest across disciplines in the aural dimensions of aesthetic experience--particularly in sociology, cultural and media theory, and literary studies--has yet to explore this fundamental category. This book furthers the discussion of rhythm beyond the discrete conceptual domains and technical vocabularies of musicology and prosody. With original essays by philosophers, psychologists, musicians, literary theorists, and ethno-musicologists, The Philosophy of Rhythm opens (...) up wider-and plural-perspectives, examining formal affinities between the historically interconnected fields of music, dance, and poetry, while addressing key concepts such as embodiment, movement, pulse, and performance. Volume editors Peter Cheyne, Andy Hamilton, and Max Paddison bring together a range of key questions: What is the distinction between rhythm and pulse? What is the relationship between everyday embodied experience, and the specific experience of music, dance, and poetry? Can aesthetics offer an understanding of rhythm that helps inform our responses to visual and other arts, as well as music, dance, and poetry? And, what is the relation between psychological conceptions of entrainment, and the humane concept of rhythm and meter? Overall, The Philosophy of Rhythm appeals across disciplinary boundaries, providing a unique overview of a neglected aspect of aesthetic experience. (shrink)

An analytic cognitive style denotes a propensity to set aside highly salient intuitions when engaging in problem solving. We assess the hypothesis that an analytic cognitive style is associated with a history of questioning, altering, and rejecting supernatural claims, both religious and paranormal. In two studies, we examined associations of God beliefs, religious engagement, conventional religious beliefs and paranormal beliefs with performance measures of cognitive ability and analytic cognitive style. An analytic cognitive style negatively predicted both religious and paranormal beliefs (...) when controlling for cognitive ability as well as religious engagement, sex, age, political ideology, and education. Participants more willing to engage in analytic reasoning were less likely to endorse supernatural beliefs. Further, an association between analytic cognitive style and religious engagement was mediated by religious beliefs, suggesting that an analytic cognitive style negatively affects religious engagement via lower acceptance of conventional religious beliefs. Results for types of God belief indicate that the association between an analytic cognitive style and God beliefs is more nuanced than mere acceptance and rejection, but also includes adopting less conventional God beliefs, such as Pantheism or Deism. Our data are consistent with the idea that two people who share the same cognitive ability, education, political ideology, sex, age and level of religious engagement can acquire very different sets of beliefs about the world if they differ in their propensity to think analytically.

According to the truthmaker theory that we favour, all contingent truths are made true by existing facts or states of affairs. But if that is so, then it appears that we must accept the existence of the negative facts that are required to make negative truths (such as 'There is no hippopotamus in the room.') true. We deny the existence of negative facts, show how negative truths are made true by positive facts, point out where the (reluctant) advocates of negative (...) facts (Russell, Armstrong, et al.) went wrong, and demonstrate the superiority of our solution to the alternatives.

Book Information The Indispensability of Mathematics. By Mark Colyvan. Oxford University Press. New York. 2001. Pp. 172. Hardback, £30.00.

A brief self-report scale was developed to assess everyday performance failures arising directly or primarily from brief failures of sustained attention . The ARCES was found to be associated with a more direct measure of propensity to attention lapses and to errors on an existing behavioral measure of sustained attention . Although the ARCES and MAAS were highly correlated, structural modelling revealed the ARCES was more directly related to SART errors and the MAAS to SART RTs, which have been hypothesized (...) to directly reflect the lapses of attention that lead to SART errors. Thus, the MAAS and SART RTs appear to directly reflect attention lapses, whereas the ARCES and SART errors reflect the mistakes these lapses are thought to cause. Boredom proneness was also assessed by the BPS, as a separate consequence of a propensity to attention lapses. Although the ARCES was significantly associated with the BPS, this association was entirely accounted for by the MAAS, suggesting that performance errors and boredom are separate consequences of lapses in attention. A tendency to even extraordinarily brief attention lapses on the order of milliseconds may have far-reaching consequences not only for safe and efficient task performance but also for sustaining the motivation to persist in and enjoy these tasks.

Since the beginning of the new millennium, initiatives known as roundtables have been developed to create voluntary sustainability standards for agricultural commodities. Intended to be private and voluntary in nature, these initiatives claim their legitimacy from their ability to ensure the participation of all categories of stakeholders in horizontal participatory and inclusive processes. This article characterizes the political and material instruments employed as the means of formulating agreement and taking a variety of voices into consideration in these arenas. Referring to (...) the specific case of the “Roundtable on Sustainable Palm Oil”, I undertake a detailed analysis of the tensions relating to different forms of participation, which create a gap between “local minority voices” and international stakeholders—either non-governmental organizations or industries. Local communities and small-scale farmers face difficulties when making their voices heard in the form of debate proposed. Firstly, some participants attempt to re-impose a vertical hierarchical relationship between small-scale farmers or affected communities and company managers/directors in order to deprive the former of their powers of representation and of being able to transform reality. Secondly, the liberalism of interest groups in the roundtable accords value to experts, global knowledge, strategy, and detachment, at the expense of other capabilities of rooted or attached people who come to defend their real lives with a desire to raise critical issues of injustice. In this context, I highlight the capacity of local NGOs to relieve some of those tensions and to help locally affected communities and small-scale farmers introduce public stages for debates, by accommodating other forms of participation apart from the liberal one. By being close to and by restoring their dignity through a specific work of solicitude and care, local NGOs prepare affected people for public speaking. (shrink)

We examined the affective consequences of everyday attention lapses and memory failures. Significant associations were found between self-report measures of attention lapses , attention-related cognitive errors , and memory failures , on the one hand, and boredom and depression , on the other. Regression analyses confirmed previous findings that the ARCES partially mediates the relation between the MAAS-LO and MFS. Further regression analyses also indicated that the association between the ARCES and BPS was entirely accounted for by the MAAS-LO and (...) MFS, as was that between the ARCES and BDI-II. Structural modeling revealed the associations to be optimally explained by the MAAS-LO and MFS influencing the BPS and BDI-II, contrary to current conceptions of attention and memory problems as consequences of affective dysfunction. A lack of conscious awareness of one’s actions, signaled by the propensity to experience brief lapses of attention and related memory failures, is thus seen as having significant consequences in terms of long-term affective well-being.

Hypnagogic and hypnopompic experiences (HHEs) accompanying sleep paralysis (SP) are often cited as sources of accounts of supernatural nocturnal assaults and paranormal experiences. Descriptions of such experiences are remarkably consistent across time and cultures and consistent also with known mechanisms of REM states. A three-factor structural model of HHEs based on their relations both to cultural narratives and REM neurophysiology is developed and tested with several large samples. One factor, labeled Intruder, consisting of sensed presence, fear, and auditory and visual (...) hallucinations, is conjectured to originate in a hypervigilant state initiated in the midbrain. Another factor, Incubus, comprising pressure on the chest, breathing difficulties, and pain, is attributed to effects of hyperpolarization of motoneurons on perceptions of respiration. These two factors have in common an implied alien ''other'' consistent with occult narratives identified in numerous contemporary and historical cultures. A third factor, labeled Unusual Bodily Experiences, consisting of floating/flying sensations, out-of-body experiences, and feelings of bliss, is related to physically impossible experiences generated by conflicts of endogenous and exogenous activation related to body position, orientation, and movement. Implications of this last factor for understanding of orientational primacy in self-consciousness are considered. Central features of the model developed here are consistent with recent work on hallucinations associated with hypnosis and schizophrenia. (shrink)

The Quine/Putnam indispensability argument is regarded by many as the chief argument for the existence of platonic objects. We argue that this argument cannot establish what its proponents intend. The form of our argument is simple. Suppose indispensability to science is the only good reason for believing in the existence of platonic objects. Either the dispensability of mathematical objects to science can be demonstrated and, hence, there is no good reason for believing in the existence of platonic objects, or their (...) dispensability cannot be demonstrated and, hence, there is no good reason for believing in the existence of mathematical objects which are genuinely platonic. Therefore, indispensability, whether true or false, does not support platonism. (shrink)

A number of multi-stakeholder initiatives and commodity roundtables have been created since the 1990s to respond to the growing criticism of agriculture’s environmental and social impacts. Driven by private and global-scale actors, these initiatives are setting global standards for sustainable agricultural practices. They claim to follow the new standard-making virtues of inclusiveness and consensus and base their legitimacy on their claim of balanced representation of, and participation by, all categories of stakeholders. This principle of representing a wide range of interests (...) with a balance of power is at the heart of a new type of action that forms part of a broader political liberal model for building coalitions of interest groups. The intention of this symposium is to assess the nature of processes and outcomes of this model while paying particular attention to the forms of inclusion and exclusion they generate. In this introduction, we highlight the differences in theoretical approaches to analyzing MSIs and the manifestation of power through them. We distinguish between more traditional political–economy approaches and approaches concerned with ideational and normative power, such as convention theory. We discuss some of the main paradoxes of MSIs related to their willingness to be “inclusive” and at the same time their exclusionary or “closure” effects due in part to interactions with existing political economic contexts and embedded power inequalities, as well as more subtle manifestations of power linked to the favoring of some forms of knowledge and engagement over others.

According to platonists, entities such as numbers, sets, propositions and properties are abstract objects. But abstract objects lack causal powers and a location in space and time, so how could we ever come to know of the existence of such impotent and remote objects? In Knowledge, Cause, and Abstract Objects, Colin Cheyne presents the first systematic and detailed account of this epistemological objection to the platonist doctrine that abstract objects exist and can be known. Since mathematics has such a central (...) role in the acquisition of scientific knowledge, he concentrates on mathematical platonism. He also concentrates on our knowledge of what exists, and argues for a causal constraint on such existential knowledge. Finally, he exposes the weaknesses of recent attempts by platonists to account for our supposed platonic knowledge. This book will be of particular interest to researchers and advanced students of epistemology and of the philosophy of mathematics and science. It will also be of interest to all philosophers with a general interest in metaphysics and ontology. (shrink)

‘PHILOSOPHY, or the doctrine and discipline of ideas’, as S. T. Coleridge understood it, is the theme of this book. It considers the most vital and mature vein of Coleridge’s thought to be ‘the contemplation of ideas objectively, as existing powers’. A theory of ideas emerges in critical engagement with thinkers including Plato, Plotinus, Böhme, Kant, and Schelling. A commitment to the transcendence of reason, central to what he calls ‘the spiritual platonic old England’, distinguishes him from his German contemporaries. (...) The book also engages with Coleridge’s poetry, especially in a culminating chapter dedicated to the ‘Limbo’ sequence. This book pursues a theory of contemplation that draws from discussions of imagination and the ‘Ideas of Reason’ in Coleridge’s published texts and extensively from his unpublished works, fragments, letters, and notebooks. He posited a hierarchy of cognition from basic sense intuition to the apprehension of scientific, ethical, and theological ideas. The structure of the book follows this thesis, beginning with sense data, moving upwards into aesthetic experience, imagination, and reason, with final chapters on formal logic and poetry that constellate the contemplation of ideas. Coleridge’s Contemplative Philosophy is not just a work of intellectual history, it addresses a figure whose thinking is of continuing interest, arguing that contemplation of ideas and values has consequences for everyday morality and aesthetics, as well as metaphysics. The volume will be of interest to philosophers, intellectual historians, scholars of religion, and of literature. (shrink)

On 18–19 May 2018, a symposium was held in the Research Institute of Irish and Scottish Studies at the University of Aberdeen to commemorate the tenth anniversary of the death of Ronald W. Hepburn (1927–2008). The speakers at this event discussed Hepburn’s oeuvre from several perspectives. For this book, the collection of the revised versions of their talks has been supplemented by the papers of other scholars who were unable to attend the symposium itself. Thus this volume contains contributions from (...) eighteen notable scholars of different disciplines, ranging from contemporary aesthetics and art theory through to philosophical approaches to religion, education and social anthropology. It also includes a bibliography of Hepburn’s writings. The essays were first published in two special issues of the Journal of Scottish Thought, vols. 10–11 (2018–2019). -/- Ronald William Hepburn was born in Aberdeen on 16 March 1927. He went to Aberdeen Grammar School, then he graduated with an M.A. in Philosophy (1951) and obtained his doctorate from the University of Aberdeen (1955). His tutor at Aberdeen was Donald MacKinnon (1913– 1994), a Scottish philosopher and theologian, the author of A Study in Ethical Theory (1957) and The Problem of Metaphysics (1974). Hepburn taught as Lecturer at the Department of Moral Philosophy at Aberdeen (1956–60), and he was also Visiting Associate Professor of Philosophy at New York University (1959–60). He returned from the United States as Professor of Philosophy at Nottingham University. In 1964, he was appointed as a Chair in Philosophy at the University of Edinburgh and between 1965 and 1968 he was also Stanton Lecturer in the Philosophy of Religion at the University of Cambridge. From 1975 until his retirement in 1996, he held the Professorship of Moral Philosophy at Edinburgh. He died in Edinburgh on 23 December 2008. His philosophical interests ranged from theology and the philosophy of religion through moral philosophy and the philosophy of education to art theory and aesthetics. Notably, Hepburn is widely regarded as the founder of modern environmental and everyday aesthetics as a result of the influence of papers in the 1960s which pioneered a new approach to the aesthetics of the natural world.

Alan Musgrave has consistently defended two positions that he regards as commonsensical: critical realism and critical rationalism. In this volume a group of internationally-renowned authors discuss themes that are relevant in one way or another to Musgrave’s work. Rather than a standard celebratory festschrift, this book offers a new examination of topics of current interest in philosophy. The contributory essays are followed by responses from Alan Musgrave himself.

Furthermore, they claim that these objects differ radically from the concrete objects (trees, cats, stars, molecules) which inhabit the material world. We take the standard platonistic position to include the claim that platonic objects lack spatio-temporal location and causal powers. Many (perhaps most) mathematical platonists subscribe to this view.1 But some who call themselves (or might be called) mathematical platonists.. (shrink)

The interplay between computability and randomness has been an active area of research in recent years, reflected by ample funding in the USA, numerous workshops, and publications on the subject. The complexity and the randomness aspect of a set of natural numbers are closely related. Traditionally, computability theory is concerned with the complexity aspect. However, computability theoretic tools can also be used to introduce mathematical counterparts for the intuitive notion of randomness of a set. Recent research shows that, conversely, concepts (...) and methods originating from randomness enrich computability theory.The book covers topics such as lowness and highness properties, Kolmogorov complexity, betting strategies and higher computability. Both the basics and recent research results are desribed, providing a very readable introduction to the exciting interface of computability and randomness for graduates and researchers in computability theory, theoretical computer science, and measure theory.

Situating Samuel Taylor Coleridge’s thought on historically actualized ideas with reference to a range of classical thinkers, this article examines his intriguing philosophical theory about how ideas become progressively actualized in history. This cultural growth can be understood as contemplation-in-action, although it occurs through mainly fumbling – or else overenthusiastic – human agents. I distinguish Coleridgean first-order, transcendent ideas (such as God, infinity, the good, the soul) from second-order, historical ones (such as church, state, the constitution). It has been argued (...) that Coleridge’s theory of ideas develops from Bacon’s inductive method for discovering laws of nature through experiment and natural law through common law. I further claim that Coleridge upholds the reality of “Forms” in science, and of rights in ethics and politics; that his later political thought is inherently more progressive than is generally admitted; and that his account differs from Schelling’s and Hegel’s respective theories by maintaining the transcendence of ideas above the immanence of their evolving historical actualizations. Coleridge’s philosophy is therefore, whether political or metaphysical, ultimately an ontological defence of the transcendence of ideas above the immanence of their progressive but imperfect actualization.

ABSTRACT: In this essay I characterize arguments by analogy, which have an impor- tant role both in philosophical and everyday reasoning. Arguments by analogy are dif- ferent from ordinary inductive or deductive arguments and have their own distinct features. I try to characterize the structure and function of these arguments. It is further discussed that some arguments, which are not explicit arguments by analogy, nevertheless should be interpreted as such and not as inductive or deductive arguments. The result is that (...) a presumed outcome of a philosophical dispute will have to be reconsidered. (shrink)

But what are functions? Here, 15 leading scholars of philosophy of psychology and philosophy of biology present new essays on functions.

More and more organisations formulate a code of conduct in order to stimulate responsible behaviour among their members. Much time and energy is usually spent fixing the content of the code but many organisations get stuck in the challenge of implementing and maintaining the code. The code then turns into nothing else than the notorious "paper in the drawer", without achieving its aims. The challenge of implementation is to utilize the dynamics which have emerged from the formulation of the code. (...) This will support a continuous process of reflection on the central values and standards contained in the code. This paper presents an assessment method, based on the EFQM model, which intends to support this implementation process. (shrink)

It is widely believed that medically inert treatments (“placebos”) can bring about therapeutic benefits. There is also evidence that medically active treatments may also have “placebo” effects. Since anything that has the potential to benefit patients ought to be exploited, subject to appropriate ethical standards, it has been suggested that more should be done to investigate and exploit the power of the placebo for therapeutic benefit. I explore the acute epistemic and ethical constraints that such exploitation is likely to face, (...) and conclude that effective exploitation is unlikely. (shrink)

Mathematics is about numbers, sets, functions, etc. and, according to one prominent view, these are abstract entities lacking causal powers and spatio-temporal location.

Threat themes are clearly over-represented in dreams. Threat is, however, not the only theme with potential evolutionary significance. Even for hypnagogic and hypnopompic hallucinations during sleep paralysis, for which threat themes are far commoner than for ordinary dreaming, consistent non-threat themes have been reported. Revonsuo's simulation hypothesis represents an encouraging initiative to develop an evolutionary functional approach to dream-related experiences but it could be broadened to include evolutionarily relevant themes beyond threat. It is also suggested that Revonsuo's evolutionary re-interpretation of (...) dreams might profitably be compared to arguments for, and models of, evolutionary functions of play. [Revonsuo]. (shrink)

Current work in language models (LMs) helps us speed up or even skip thinking by accelerating and automating cognitive work. But can LMs help us with critical thinking -- thinking in deeper, more reflective ways which challenge assumptions, clarify ideas, and engineer new concepts? We treat philosophy as a case study in critical thinking, and interview 21 professional philosophers about how they engage in critical thinking and on their experiences with LMs. We find that philosophers do not find LMs to (...) be useful because they lack a sense of selfhood (memory, beliefs, consistency) and initiative (curiosity, proactivity). We propose the selfhood-initiative model for critical thinking tools to characterize this gap. Using the model, we formulate three roles LMs could play as critical thinking tools: the Interlocutor, the Monitor, and the Respondent. We hope that our work inspires LM researchers to further develop LMs as critical thinking tools and philosophers and other 'critical thinkers' to imagine intellectually substantive uses of LMs. (shrink)

According to standard mathematical platonism, mathematical entities (numbers, sets, etc.) are abstract entities. As such, they lack causal powers and spatio-temporal location. Platonists owe us an account of how we acquire knowledge of this inaccessible mathematical realm. Some recent versions of mathematical platonism postulate a plenitude of mathematical entities, and Mark Balaguer has argued that, given the existence of such a plenitude, the attainment of mathematical knowledge is rendered non-problematic. I assess his epistemology for such a profligate platonism and find (...) it unsatisfactory because it lacks an adequate semantics, in particular, an adequate account of reference. (shrink)

IN the last decade deliberative democracy has developed rapidly from a “theoretical statement” into a “working theory.”1 Scholars and practitioners have launched numerous initiatives designed to put deliberative democracy into practice, ranging from deliberative polling to citizen summits.2 Some even advocate deliberation as a new “revolutionary now.”3 Deliberative democracy has also experienced the beginning of an empirical turn, making significant gains as an empirical (or positive) political science. This includes a small, but growing body of literature tackling the connection between (...) the normative standards of deliberation, how well they are met, and the empirical consequences of meeting them.4 This trend has, for instance, included the use of methods and frameworks borrowed from other fields, such as political and social psychology. Such studies suggest that cases approaching ideal deliberation are rare, but that group interaction sometimes works surprisingly well according to such ideals.5. (shrink)

Frühgeborene im Grenzbereich der Lebensfähigkeit befinden sich in einer prognostischen Grauzone. Das bedeutet, dass deren Prognose zwar schlecht, aber nicht hoffnungslos ist, woraus folgt, dass nach Geburt lebenserhaltende Behandlungen nicht obligatorisch sind. Die Entscheidung für oder gegen lebenserhaltende Maßnahmen ist wertbeladen und für alle Beteiligten enorm herausfordernd. Sie sollte eine zwischen Eltern und Ärzt*innen geteilte Entscheidung sein, wobei sie unbedingt mit den Präferenzen der Eltern abgestimmt sein sollte. Bei der pränatalen Beratung der Eltern legen die behandelnden Ärzt*innen üblicherweise numerische Schätzungen (...) der Prognose vor und nehmen in der Regel an, dass die Eltern ihre Behandlungspräferenzen davon ableiten. Inwieweit probabilistische Daten die Entscheidungen der Eltern in prognostischen Grauzonen tatsächlich beeinflussen, ist noch unzureichend untersucht. In der hier vorliegenden Arbeit wird eine Studie reflektiert, in welcher die Hypothese geprüft wurde, dass numerisch bessere oder schlechtere kindliche Prognosen die Präferenzen werdender Mütter für lebenserhaltende Maßnahmen nicht beeinflussen. In dieser Studie zeigte sich, dass die elterlichen Behandlungspräferenzen eher von individuellen Einstellungen und Werten als von Überlegungen zu numerischen Ergebnisschätzungen herzurühren scheinen. Unser Verständnis, welche Informationen werdende Eltern, die mit einer extremen Frühgeburt konfrontiert sind, wünschen und brauchen, ist noch immer unvollständig. Bedeutende medizinische Entscheidungen werden keineswegs nur rational und prognoseorientiert gefällt. In der vorliegenden Arbeit wird diskutiert, welchen Einfluss der Prozess der Entscheidungsfindung auf das Beratungsergebnis haben kann und welche Implikationen sich aus den bisher vorliegenden Studienergebnissen ergeben – klinisch-praktisch, ethisch und wissenschaftlich.
