It is well known that the Penrose–Banzhaf index of a weighted game can differ starkly from corresponding weights. Limit results are quite the opposite, i.e., under certain conditions the power distribution approaches the weight distribution. Here we provide parametric examples that give necessary conditions for the existence of limit results for the Penrose–Banzhaf index.

This paper has a twofold scope. The first one is to clarify and put in evidence the isomorphic character of two theories developed in quite different fields: on one side, threshold logic, on the other side, simple games. One of the main purposes in both theories is to determine when a simple game is representable as a weighted game, which allows a very compact and easily comprehensible representation. Deep results were found in threshold logic in the sixties and seventies for (...) this problem. However, game theory has taken the lead and some new results have been obtained for the problem in the past two decades. The second and main goal of this paper is to provide some new results on this problem and propose several open questions and conjectures for future research. The results we obtain depend on two significant parameters of the game: the number of types of equivalent players and the number of types of shift-minimal winning coalitions. (shrink)

A main goal of the neuroscience of consciousness is: find the neural correlate to conscious experiences (NCC). When have we achieved this goal? The answer depends on our operationalization of “NCC.” Chalmers (2000) shaped the widely accepted operationalization according to which an NCC is a neural system with a state which is minimally sufficient (but not necessary) for an experience. A deeper look at this operationalization reveals why it might be unsatisfactory: (i) it is not an operationalization of a correlate (...) for occurring experiences, but of the capacity to experience; (ii) it is unhelpful for certain cases which are used to motivate a search for neural correlates of consciousness; (iii) it does not mirror the usage of “NCC” by scientists who seek for unique correlates; (iv) it hardly allows for a form of comparative testing of hypotheses, namely experimenta crucis. Because of these problems (i–iv), we ought to amend or improve on Chalmers's operationalization. Here, I present an alternative which avoids these problems. This “NCC2.0” also retains some benefits of Chalmers's operationalization, namely being compatible with contributions from extended, embedded, enacted, or embodied accounts (4E-accounts) and allowing for the possibility of non-biological or artificial experiencers.

Ground Representationism is the position that for each phenomenal feature there is a representational feature that accounts for it. Against this thesis, Ned Block (The Puzzle of Phenomenal Precision, 2015) has provided an intricate argument that rests on the notion of “phenomenal precision”: the phenomenal precision of a percept may change at a different rate from its representational counterpart. If so, there is then no representational feature that accounts for a specific change of this phenomenal feature. Therefore, Ground Representationism cannot (...) be generally true. -/- Although the notion of phenomenal precision is intuitive, it is admittedly in need of clarification. Here I reconstruct Block’s argument by suggesting a way of estimating phenomenal precision that is based on the assumption that parts of perceptual wholes can share phenomenal features independently of their place in the whole. Understood like this, the overall argument shows what it is supposed to show. -/- A more thorough look at the notion of phenomenal precision suggests tension with Block’s other work: in order to be non-trivial, we have to accept that some of our phenomenality is not concrete, but only generic. Such “solely generic phenomenology”, however, is a position mainly held by opponents to Block’s Access- vs. Phenomenal Consciousness-distinction. Interpreting phenomenal imprecision as constituted by introspective imprecision does not suffice as a way out. It seems that phenomenal precision is either trivial, self-contradictory, or incompatible with Block’s position elsewhere. So some additional elucidation on this crucial notion is needed. (shrink)

This compelling book contains a comprehensive analytical treatment of the theory of production in a long-period framework. Although the authors take a 'Classical' approach to their subject, the scope of investigation and methods employed should interest all economic theorists. Professors Kurz and Salvadori explore economic systems that are characterised by a particular kind of primary input in the production process, such as different kinds of labour and natural resources. These systems and the corresponding prices can be understood to reflect (...) characteristic features of a capitalist market economy in an ideal way: they express the pure logic of the relationship between value and distribution in an economic system. Specific chapters deal with prices and income distribution, economic growth, joint production, fixed capital, scarce natural resources, and heterogeneous labour. The historical origins of the concepts used are also discussed in considerable detail. (shrink)

Over the past 12 years, I’ve had the good fortune of collaborating with others to create a project which challenges and complicates the dominant biopsychiatric model of mental illness. The Icarus Project, founded in 2002, not only critiqued the terms and practices central to the biopsychiatric model, it also inspired a new language and a new community for people struggling with mental health issues in the 21st century. The Icarus Project believes that humans are meaning makers, that meaning is created (...) through developing intrapersonal and interpersonal narratives, and that these narratives are important sites of creativity, struggle, and growth. The Icarus counter narrative and the community it fostered has been invaluable for people around the world dealing with psychic diversity—particularly for people alienated by mainstream approaches. But, despite the numbers of people who have been inspired by this approach, the historical background of the Icarus Project is hard to find. It exists primarily in oral history, newspaper articles, unpublished or self-published Icarus documents, and in internet discussion forums. As the co-founder of the Icarus Project, I use this article to make my understanding of that history and its key documents more widely available. (shrink)

The violation of Bell inequalities by quantum physical experiments disproves all relativistic micro causal, classically real models, short Local Realistic Models (LRM). Non-locality, the infamous “spooky interaction at a distance” (A. Einstein), is already sufficiently ‘unreal’ to motivate modifying the “realistic” in “local realistic”. This has led to many worlds and finally many minds interpretations. We introduce a simple many world model that resolves the Einstein Podolsky Rosen paradox. The model starts out as a classical LRM, thus clarifying that the (...) many worlds concept alone does not imply quantum physics. Some of the desired ‘non-locality’, e.g. anti-correlation at equal measurement angles, is already present, but Bell’s inequality can of course not be violated. A single and natural step turns this LRM into a quantum model predicting the correct probabilities. Intriguingly, the crucial step does obviously not modify locality but instead reality: What before could have still been a direct realism turns into modal realism. This supports the trend away from the focus on non-locality in quantum mechanics towards a mature structural realism that preserves micro causality. (shrink)

Chris Letheby argues in Philosophy of Psychedelics that psychedelics and knowledge are compatible. Psychedelics may cause new mental states, some of which can be states of knowledge. But the influence of psychedelics is largely psychological, and not all psychological processes are epistemic. So I want to build on the distinction between processes of discovery and processes of justification to criticise some aspects of Letheby’s epistemology of psychedelics. Unarguably, psychedelics can elicit processes of discovery. Yet, I hold, they can hardly contribute (...) either to the epistemic success of a mental state or to processes of justification. As these are central for a mental state to be a state of knowledge and are largely uninfluenced by psychedelics, the contributions of psychedelics to knowledge are rather indirect than direct: The heavy epistemic lifting—what turns a mental state into a state of knowledge—is, in its epistemic aspects, independent of any influence of psychedelics on our psyche. Positively, while the mechanisms that Letheby points to need not be associated with knowledge, they do provide crucial epistemic benefits if they are associated with understanding. Reading them as facilitating understanding covers also those cases where truth or justification is missing and thereby provides a broader picture of the epistemic contributions of psychedelics.

This study investigates the distinct and joint effects of corporate social performance, firm size, and visibility on a company’s decision to disclose sustainability-related information through sustainability reports. It seeks to provide more nuanced explanations for why certain companies tend to extensively report on their sustainability performance. First, while prior studies have predominantly focused on environmental reporting, the current analysis considers comprehensive sustainability reports that include both environmental and social issues. Second, the article argues that the effects of two important antecedents (...) of legitimacy pressure—firm size and organizational visibility—should be analyzed separately rather than restricting the analysis on the effects of legitimacy pressure per se. Third, it argues that the hypothesized effects are nonlinear because the marginal costs and benefits of sustainability reporting vary with a company’s CSP level, its size, and its visibility in the public. Finally, although there is a strong link between CSP and sustainability reporting, the strength of this link depends on its size and visibility. The study of 280 companies in environmentally and socially sensitive industries provides considerable support for these hypotheses, including evidence that size and visibility independently affect sustainability reporting and that the shape of the CSP/sustainability reporting link is contingent upon firm size and visibility.

On some accounts, prostitution is just another form of casual sex and as such not particularly harmful in itself, if regulated properly. I claim that, although casual sex in general is not inher-ently harmful, prostitution in fact is. To show this, I defend an account of sex as joint action characteristically aimed at sexual enjoyment, here understood as a tangible experience of com-munity among partners, and argue that prostitution fails to achieve this good by incentivizing partners to mistreat each other. (...) To substantiate this claim, I explore ways in which prostitution fails on the virtues of temperance, respect, and sincerity. (shrink)

Wittgenstein took literature extremely seriously and did not consider it of secondary importance. However, academic philosophy often shies away from the literary inflection of his philosophy. This is the first book to provide detailed discussions of his engagement with individual authors, such as Dostoevsky, Goethe, and Shakespeare. The book is essential for the cultural contextualizationfor Wittgenstein scholars and scholars of literature.

In serial verb constructions (SVCs), multiple independent lexical verbs are combined in a mono-clausal construction. SVCs express a range of grammatical meanings and are attested in numerous spoken languages all around the world. Yet, to date only few studies have investigated the existence and functions of SVCs in sign languages. For the most part, these studies—including a previous study on Sign Language of the Netherlands (NGT)—relied on elicited data. In this article, we offer a cross-modal typological contribution to the study (...) of SVCs by investigating the phenomenon based on naturalistic corpus data from NGT. A search of the Corpus NGT yielded 41 mono-clausal utterances in which one of a closed set of verbs—namely go, give, take, and call —combines with another lexical verb. While the combinations we found are in important respects reminiscent of SVCs described for spoken languages, our data also confirm the previous finding that the fixed verb in the SVC serves to express agreement (by means of spatial modulation) when the other verb cannot do so. In addition, we identified some novel uses of the verbs go and give: (i) go functioning as a future tense marker and (ii) give functioning as a light verb. We will also discuss aspects of the grammaticalization of SVCs in NGT: from lexical verb to light verb to auxiliary, again offering some comparison to grammaticalization paths described for spoken languages.

The prevention of sexual violence is a major goal of sexual health. In cases of accused sexual offenders, the assessment of diminished criminal responsibility of the accused is one of the most important procedures undertaken by experts in the German legal system. This assessment follows a two-stage method assessing first the severity of a paraphilic disorder and then second criteria for or against diminished capacity. The present study examines the predictive validity of two different sets of criteria for the assessment (...) of criminal responsibility in the context of paraphilic disorders combined with sexual offending. Two exemplary case vignettes of two suspected sexual offenders were developed to assess the criteria. For each participant, one of the two exemplary case vignettes was randomly presented. The presentation of the two different sets of criteria was also randomized, so that each participant was assigned only one of the two criteria sets to rate one of the presented cases. N = 349 participants from different professional backgrounds completed their assessments and were included in the data analysis. The data were evaluated using logistic regression. Results show that the more recently published criteria set predicts both the severity of the disorder as well as the diminished capacity twice as good as the older criteria set of Boetticher et al. currently used regularly for forensic court reports. In preliminary conclusion, the new criteria of Briken and Müller form an empirically based assessment of criminal responsibility. However, the proposed criteria cannot replace an extensive exploration of the accused person and a careful file analysis. Validity and reliability of the results are also limited due to the methodical choice of a vignette study. (shrink)

Although the relationship between Charles Sanders Peirce and German philosophy was a very close one, it remained rather one-sided for a long time. This story would make for a philosophical tragicomedy in three acts, but in what follows I will keep it as sober and short as possible. * 1. As is well known, Peirce came into contact with philosophy via Kant and German Idealism (especially Schelling and Hegel). He read Kant in German from the age of 14 on and (...) his own philosophical works – the earl... (shrink)

The philosophical allegation of imposture levelled by the Radical Enlightenment at Moses, Jesus, and Muhammad – the three founders of the monotheistic religions – has a complex theological history. Strange as it may sound, it is an idea closely connected to some of the “dangerous” debates conducted by scholastic theologians. Some of these theologians described divine omnipotence in a manner that prompted the vexed question of whether God can deceive us. Of course, no theologian doubted that God could and yet (...) would not deceive us. However, for some scholastics, God permitted the Devil to deceive men. After the Reformation, the Devil assumed a central role in debates between the Christian denominations. Depending on one’s confessional allegiance, the Devil could be the Pope or Luther or Calvin. In this way, the churches of post-Reformation Europe contributed to a process by which the Devil was transformed into the human figure of the “impostor,” preparing the ground, as this article shows, for later, more radical criticisms of religion per se.

This paper describes the affinities between Socinian and Unitarian materialism. Based on different philosophical traditions, the Socinian Christoph Stegmann and the Unitarian Joseph Priestley developed a strong “system of materialism” which fit very well with Christian doctrines and the Bible. The conviction that the whole man is material and therefore mortal became the common basis for these radical thinkers. Stegmann formulated within the Aristotelian tradition a “non-reductive” materialism in which matter, not form, became the fundamental principle of all living things. (...) Priestley, on the other hand, created his “absolute” materialism by developing a new understanding of the concept of matter according to the philosophical rules of Isaac Newton. The paper will discuss the affinities and differences between these two different concepts of materialism. The idea of a thinking matter, most prominently formulated by John Locke, will serve as a link between them. (shrink)

A central objection to McDowell’s conceptualism about empirical content concerns the fine-grained phenomenology of experience, which supposedly entails that the actual content of experience cannot be matched in its particularity by our concepts. While McDowell himself has answered this objection in recourse to the possibility of demonstrative concepts, his reply has engendered a plethora of further objections and is widely considered inadequate. I believe that McDowell’s critics underestimate the true force of his reply because they tend to read unrecognized empiricist (...) presuppositions into his account of experience. To show this, I introduce a new hylomorphic reading of McDowell’s account of experience and argue that the objections to his reply all rest on a specific empiricist assumption, which is untenable because it conflates the form of experience with its content. Consequently, conceptualism so understood can resist all of these objections, as I attempt to show by systematizing and answering them. (shrink)

In intuitions concerning semantic coherence participants are able to discriminate above chance whether a word triad has a common remote associate or not . These intuitions are driven by increased fluency in processing coherent triads compared to incoherent triads, which in turn triggers a brief and short positive affect. The present work investigates which of these internal cues, fluency or positive affect, is the actual cue underlying coherence intuitions. In Experiment 1, participants liked coherent word triads more than incoherent triads, (...) but did not rate them as being more fluent in processing. In Experiment 2, participants could intuitively detect coherence when they misattributed fluency to an external source, but lost this intuitive ability when they misattributed affect. It is concluded that the coherence-induced fluency by itself is not consciously experienced and not used in the coherence intuitions, but the fluency-triggered affective consequences. (shrink)

How to model non-egoic experiences – mental events with phenomenal aspects that lack a felt self – has become an interesting research question. The main source of evidence for the existence of such non-egoic experiences are self-ascriptions of non-egoic experiences. In these, a person says about herself that she underwent an episode where she was conscious but lacked a feeling of self. Some interpret these as accurate reports, but this is questionable. Thomas Metzinger, Rocco Gennaro, and Charles Foster have hinted (...) at the self-defeating nature of such statements if we take them to be genuine reports: Apparently, the reporter explicitly denies her existence during the selfless experience, but implicitly affirms her existence as a witness to that selfless experience in order to give a first-person report about it. So the content of such a report conflicts with the pragmatics of reporting. If all self-ascriptions of non-egoic experiences are self-defeating in this way, then they cannot count as evidence for the existence of non-egoic experiences. Here, I map out why such strong conclusions do not directly follow: What look like self-ascriptions of non-egoic experiences may occur for a number of reasons. Only some explanations for such utterances rely on a change in consciousness. Of those that do rely on a change in consciousness, only one is incoherent. But its alternatives do not lead to contradictions. I argue that the most likely change in phenomenality that leads to self-ascriptions of non-egoic experiences is not one where a felt self disappears, but where it expands. (shrink)

Sceptics vis-à-vis introspection often base their scepticism on ‘phenomenological disputes’, ‘introspective disagreement’, or ‘introspective disputes’ (Kriegel, 2007; Bayne and Spener, 2010; Schwitzgebel, 2011): introspectors massively diverge in their opinions about experiences, and there seems to be no method to resolve these issues. Sceptics take this to show that introspection lacks any epistemic merit. Here, I provide a list of paradigmatic examples, distill necessary and sufficient conditions for IDs, present the sceptical argument encouraged by IDs, and review the two main strategies (...) to reject such a scepticism. However, both types of strategies are unsatisfactory. In order to save introspection from the looming sceptical threat, I advocate a deflationary strategy, based on either an ‘Argument from Perceptual Kinship’ or an ‘Argument from Ownership’. In the end, there cannot be any genuine IDs, for nothing can fulfil the reasonable conditions for IDs. What looks like IDs may instead be indicators of phenomenal variation. Debates that look like IDs may then arise even if introspection were a perfect method to know one’s mind. Thus, scepticism vis-à-vis introspection based on IDs rests on shaky grounds. (shrink)

At least two distinct modeling frameworks contribute to the view that mind and brain are Bayesian: Bayesian Rational Analysis (BRA) and Hierarchical Predictive Coding (HPC). What is the relative contribution of each, and how exactly do they relate? In order to answer this question, we compare the way in which these two modeling frameworks address different levels of analysis within Marr’s tripartite conception of explanation in cognitive science. Whereas BRA answers questions at the computational level only, many HPC-theorists answer questions (...) at the computational, algorithmic, and implementational levels simultaneously. Given that all three levels of analysis need to be addressed in order to explain a behavioral or cognitive phenomenon, HPC seems to deliver more complete explanations. Nevertheless, BRA is well-suited for providing a solution to the dark room problem, a major theoretical obstacle for HPC. A combination of the two approaches also combines the benefits of an embodied-externalistic approach to resolving the dark room problem with the idea of a persisting evidentiary border beyond which matters are out of cognitive reach. For this reason, the development of explanations spanning all three Marrian levels within the general Bayesian approach may require combining the BRA and HPC modeling frameworks. (shrink)

With the Internet’s integration into mainstream society, online technologies have become a significant economic factor and a central aspect of everyday life. Thus, it is not surprising that news providers and social scientists regularly offer media-induced visions of a nearby future and that these horizons of expectation are continually expanding. This is true not only for the Web as a traditional media technology but also for 3D printing, which has freed modern media utopianism from its stigma of immateriality. Our article (...) explores the fundamental semantic structures and simplification patterns of popular media utopias and unfolds the thesis that their resounding success is based on their instantaneous connectivity and compatibility to societal discourses in a broad variety of cultural, political, or economic contexts. Further, it addresses the social functions of utopian concepts in the digital realm. (shrink)

The present paper aims to contribute to the substantivalism versus relationalism debate and to defend general relativity (GR) against pseudoscientific attacks in a novel, especially inclusive way. This work was initially motivated by the desire to establish the incompatibility of any ether theories with accelerated cosmic expansion and inflation (motto: where would a hypothetical medium supposedly come from so fast?). The failure of this program is of interest for emergent GR concepts in high energy particle physics. However, it becomes increasingly (...) important to guard scientific results against their misrepresentation by fundamentally anti-scientific agendas. We therefore argue that although it is not known whether the perceived space-time is fundamental (rather than a condensed state or a particular membrane), in a fundamental theory, space-time must be abstract relational: fundamental space-time is the consistent spatial-temporal arrangement of events. To pursue its own goals, this work should be accessible to a wide audience: physicists, philosophers of science, those being tempted by anti-relativity theories, but also those who vigorously defend some orthodox relativity that is not actually supported by GR. It must thus be extensive in order to satisfy the different parties’ desire to have included and understood their respective positions. (shrink)

There is tension between commonly held views concerning phenomenal imagery on the one hand and our first-person epistemic access to it on the other. This tension is evident in many individual issues and experiments in philosophy and psychology (e.g. inattentional and change blindness, the speckled hen, dream coloration, visual periphery). To dissolve it, we can give up either (i) that we lack full introspective access to the phenomenal properties of our imagistic experiences, or (ii) that phenomenal imagery is fully determined, (...) or (iii) that phenomenal imagery does not exist. Which option is preferable? I explore the feasibility of option (ii) in more details by distinguishing between di erent kinds of indeterminacy. One of the most often proclaimed versions of indeterminacy is tied to Representationalism. However, I argue that in this context, Representationalism appears to be the least satisfying option, for which I give ten reasons. By abduction, we should reject Representationalism in favour of (i) or (iii)—the most parsimonious option being eliminativism, and the most conservative being the rejection of privileged access. The decision between these two, however, should be made on a case-by-case basis, depending on which is most adequate given the data. I illustrate this with the comparison between visual agnosia and Charles-Bonnet-Syndrome. (shrink)

This review presents a systematic reading of Peter Sloterdijk’s Spheres trilogy, as part of a larger project to develop a techno-social ontology of place/s. Arguing against universalising theories of time and space, including Sloterdijk’s own conception of Spheres as ‘Being and Space’, this essay reads the trilogy through a ‘platial’ framework. While commenting on some of the shortcomings of the official English translations, the three volumes are being worked through methodically – Bubbles (micro spherology), Globes (macro spherology) and Foams (plural (...) spherology) – by placing particular emphasis on the third book, where Sloterdijk’s logic of spheres converges. The essay concludes by pointing out the limitation of Spheres as (philosophical) anthropology. (shrink)

L’omission de clitiques sujets préverbaux en frioulan : méthodologie et analyse à base de contraintesEn frioulan, les clitiques sujets en position préverbale sont omis en général quand le verbe est précédé de la particule négative, d’un clitique objet ou d’un pronom réfléchi. Toutefois, les conditions précises de cette omission n’ont pas été analysées jusqu’à présent de manière approfondie. Dans cet article, je propose une analyse dans le cadre de la théorie de l’optimalité fondée sur des données empiriques. L’analyse est basée (...) sur des jugements de grammaticalité de 52 locuteurs représentant les trois principales variétés frioulanes. Les données sont aussi comparées à celles d’un autre corpus, une bible frioulane. L’article conclut que l’omission des clitiques sujets est déterminée par la phonologie et par une stratégie visant à éviter les syncrétismes. (shrink)

This article shows how research on the social structure of markets may contribute to the analysis the growing income inequality in contemporary capitalist economies. The author proposes a theoretical link between embeddedness and social stratification by discussing the role of institutions and networks in markets for the distribution of economic profits between firms. The author claims that we must understand profit and free competition as opposites, as economic theory does. In the main part of the article the author illustrates six (...) typical mechanisms of rent extraction from networks or formal and symbolic rules that embed markets. They emerge from material as well as symbolical access to and influence on the orientation of other market actors. Social structures in markets lead to unequal chances for rent extraction, even if actors produce them for coordination rather than for accumulation purposes. This is how market sociology and theory of capitalism can be linked more closely. (shrink)

Thomas Metzinger has diagnosed the need for a Bewusstseinskultur, a ‘consciousness culture’: a culturally implemented way in which a society as a whole engages with the dawning natural science of consciousness, with phenomenal experiences themselves, and with our increasing capability to manipulate them. A Bewusstseinskultur is an achievement, built by a society-wide orientation on empirical evidence, thorough scientific theorizing and rational deliberation. It affects a broad range of issues from animal ethics, drug policy, end-of-life-care, and robo-ethics to post-humanism. However, this (...) notion has not yet been presented in English, and is so far unconnected to other discussions in philosophy. Here, I remedy this: I present Metzinger's notion of a Bewusstseinskultur and connect it to discussion on transformative experiences, Parfit's meta-hedonic states, and the Access vs. Phenomenal Consciousness distinction.

In der Diskussion um personale Identität nehmen die einflussreichen Arbeiten Derek Parfits eine Sonderstellung ein, insofern Parfit nicht bestrebt ist, eines der gängigen Identitätskriterien zu verteidigen, sondern vielmehr behauptet, dass unsere alltäglichen wie philosophischen Vorstellungen von personaler Identität unrettbar inkohärent sind und deshalb aufgegeben werden sollten. In seinem Beitrag beleuchtet Sascha Settegast die verschiedenen Argumente, die Parfit für diese provokante These vorbringt, und unternimmt insbesondere den Versuch einer systematischen Dekonstruktion der wichtigsten Gedankenexperimente Parfits, die zeigen soll, dass sich diese (...) Gedankenexperimente auf eine Weise auflösen lassen, die unsere alltäglichen Intuitionen über personale Identität intakt belässt. Settegast entwickelt dabei die Grundzüge einer Konzeption personaler Identität, die sich einerseits von den gängigen neo-lockeanischen und animalistischen Ansätzen abgrenzt und andererseits bewusst an den zeitgenössischen Neo-Aristotelismus in der Ethik anknüpft, wie er etwa bei Philippa Foot und Michael Thomp-son anzutreffen ist. Die diachrone numerische Identität menschlicher Personen gründet nach Settegasts Auffassung darin, dass der Verlauf ihres Lebens eine zeitliche Einheit aufweist, die dadurch bedingt ist, dass ihre Lebensführung die menschliche Lebensform auf eine individuell charakteristische Weise exemplifiziert. Insofern dies aber nur durch Kultivierung der Tugen-den zu erreichen ist, handelt es sich laut Settegast bei personaler Identität letztlich nicht um eine Tatsache, die einfach vorliegt oder nicht, sondern um eine Aufgabe, die uns als Menschen gegeben ist und wesentlich darin besteht, in bewusster Orientierung auf das gute Leben hin ein stabiles, sich zeitlich durchhaltendes Selbst allererst auszubilden.

Biographical note: Sascha Bru, Genth University, Belgium; Peter Nicholls, University of Sussex, UK.

To process information selectively and to continuously fine-tune selectivity of information processing are important abilities for successful goal-directed behavior. One phenomenon thought to represent this fine-tuning are conflict adaptation effects in interference tasks, i.e. reduction of interference after an incompatible trial and when incompatible trials are frequent. The neurocognitive mechanisms of these effects are currently only partly understood and results from brainimaging studies so far are mixed. In our study we validate and extend recent findings by examining adaption to recent (...) conflict in the classical Stroop task using functional magnetic resonance imaging. Consistent with previous research we found increased activity in a fronto-parietal network comprising the medial prefrontal cortex, ventro-lateral prefrontal cortex, and posterior parietal cortex when contrasting incompatible with compatible trials. These areas have been associated with attentional processes and might reflect increased cognitive conflict and resolution thereof during incompatible trials. While carefully controlling for non-attentional sequential effects we found smaller Stroop interference after an incompatible trial (conflict adaptation effect). These behavioral conflict adaptation effects were accompanied by changes in activity in visual color-selective areas (V4, V4α), while there was no modulation by previous trial compatibility in a visual word-selective area (VWFA). Our results provide further evidence for the notion, that adaptation to recent conflict seems to be based mainly on enhancement of processing of the task-relevant information. (shrink)
