We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the elderly an increased improvement (...) after a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

In the article, through the prism of the existential philosophy of S. Kierkegaard, K. Jaspers, G.-G. Gadamer and J.-P. Sartre, as well as the theory of ideology of K. Manheim, the personality of the main character of M. Y. Lermontov's drama "Masquerade" – Arbenin is analyzed. The author of the article claims that Arbenin is in a state of existential despair and finds himself in a borderline situation. At the same time, in the drama "Masquerade", the ideals of Romanticism are (...) reduced to a post-Romantic ideology. Lermontov does this intentionally in order to condemn the ideological perversion of the ideals of romantic culture. The drama also focuses on the general cultural border situation: how to protect yourself from the temptations of ideology at a time when existing ideals and values are disappearing. The author of the article comes to the conclusion that in "Masquerade" Lermontov praises the romantic ideals of rebellious spirit and will, transcendent love and insight, even when he shows the dangers of turning these ideals into ideology. But "Masquerade" is not a romantic drama. This is a drama about romanticism, that is, about how the ideals of romantic culture can be perverted into an ideology that deceives and destroys people, destroying their unique existence, instead of elevating them. "Masquerade" is a variant of Lermontov's reaction to the difficulties that arose in his post–romantic, transitional time. Conveying his admiration for the ideals of romantic culture, Lermontov embodies one of the types of reaction to the realization of the decline of these ideals – the stereotypical reduction of the romantic worldview and values to a set of ideological concepts. But by portraying Arbenin, Lermontov hints at the possibility of recognizing that the worldview and values of Romanticism are losing their authority and integrity and that turning them into an ideology does not compensate for this loss. We need to find a new worldview, new values, new ideals. (shrink)

This paper attempts to put some order among the different notions of pain that are to be found in the Nietzschean philosophical corpus. It tries to show that there is a mutation of the Nietzschean concept of pain, from the notion of pain as evaluation to that of pain as localization of a commotion. Therefore pain is not in itself the source of a reaction, but is actually a consequence of a commotion that a reaction has already addressed (...) by the time of the appearance of pain. A deeper notion of pain is therefore sketched here, one that depicts it as an illusory reaction, destined at separating the global commotion of the organism from its alleged localized cause, thus separating the action from the agent and postponing the facing of the global effect of the commotion. It is for this reason that pain becomes a kind of “matrix” for the understanding of our interior life for Nietzsche, as well as a philosophical indicator of his theoretical adversaries. Finally, the end of this article attempts to show that certain positive indications for a different status of pain might serve as guiding lines for the uncovering of a Nietzschean theory of action.

Imagine a character, Mary Analogue, who has a complete theoretical knowledge of her subject matter: the illusory nature of self. Suppose that when presenting her paper on no self at a conference she suffers stage-fright – a reaction that implies she is under an illusion of the very self whose existence she denies. Might there be something defective about her knowledge of no self? The Buddhist tradition would claim that Mary Analogue, despite her theoretical omniscience, lacks deep ‘insight (...) knowledge’ into the reality of no self. The only way for her to gain insight, and thereby improve her epistemic status, would be to divest her mind of the self-illusion. In this paper, I offer an analysis of what could be epistemically involved in the process of acquiring such insight knowledge whereby one becomes, in Buddhist parlance, ‘awakened’. (shrink)

Science promises benefits, some true and some illusory. Consider a scientific agnostic who thinks that to reap the true benefits of a scientific theory he does not have to believe in its theoretical posits. Instead, it is enough if he believes that the theory successfully predicts the behavior of the observables, as ultimately only such predictions matter. -/- Say, however, that given the results of her thorough research, a psychologist proposes a theory describing a psychological mechanism underlying a certain (...) class of normative judgments. Moreover, the mechanism seems unfit for the task—once you see the details of the mechanism, you will realize that this is not the way they should be produced. Therefore, if the psychologist is right, it seems that these normative judgments should not inform one's normative theorizing or one's actions (Greene 2008, 2014, Kelly 2014). And say that the agnostic accepts the psychologist's theory, trusting that it makes correct predictions about, for example, fMRI images and subjects' reaction times, as they are observable. He also thinks that if the psychologist's description of the mechanism is correct, the judgments should not be trusted. Yet, since the mechanism posited by the theory is not observable, the agnostic is agnostic about it. He thus cannot be convinced that these judgments are produced in a flawed way and, consequently, has no reason to distrust them. -/- Scientific agnosticism comes, therefore, at the cost of dismissing normative arguments that invoke unobservable posits of psychological models. The ability to make such arguments is a true (rather than illusory) benefit of science, despite the agnostic's promise that his philosophical theory leaves intact benefits that genuinely matter.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.1 (2003) 99-102 [Access article in PDF] Living with Contested Knowledge and Partial Jennifer Clegg and Richard Lansdall-Welfare THESE CAREFUL AND CONSTRUCTIVE comments bring grist to our mill. Before responding to them, we observe first that they offer no substantive challenge to our thesis: ambiguities associated with meaning in the disabled life make it more likely that professional service providers will make dogmatic responses to (...) bereavement, and perhaps other essentially contested topics, responses that are defended by isolationism.Some welcome ideas came from left field to refresh our thinking, such as Colman's observations on the gendered nature of care. She reminded us that although the audit from which these cases came was established to investigate bereavement in general among adults with intellectual disability, its rough and ready sampling failed to ensure the expected range of bereavement types. Somehow the bereavements constructed as relevant for audit all transpired to concern the death of mothers. Moreover, of the six relatives who agreed to be interviewed concerning these bereavements, two were stepfathers and four were sisters. Colman underlines the invisibility of care work usually done by female family members: how wise or less wise decisions create the conditions for bereavement reactions, and how changes to care arrangements following bereavement fall most heavily on them. Traustadottir (2002) discussed the way new care initiatives often put pressure on female family members and staff to do more unpaid work. For example, Circles of Support encourages them to include people with intellectual disability in their personal social networks, without considering the personal costs. Such observations have yet to emerge from the umbrella of feminist research. Separatism has served feminism well, but issues of women and care do need to find their place in mainstream reviews.Another useful reminder from Colman is that the person with intellectual disability is not the only concern to families, although only a few adult services manage to hold wider systemic factors in mind (Clegg and Burnham 2000). If the person may make naïve comments at a funeral that would devastate family members whose needs take priority, the person will be excluded.The potency of bereavement was discussed twice. Casenave suggests that because "disability is a loss experience" bereavement resonates with it, casting some doubt onto the suggestion that our thesis generalizes to other contested topics. Reinders criticizes clinicians for being purblind to the tragic. The anonymous reviewer who questioned [End Page 99] the relevance of our discussion of the quality of "presence," a quality Reinders considers highly relevant, illustrates the point better than we can. Recognizing the way clinicians have little "patience with the notion of the tragic" encourages reflection on what other human experiences fail to capture our attention.Although these are all potentially valuable directions, we focus here on comments that may enhance our ability to work without dogma. Since at least the 1980s, clinicians in intellectual disability have criticized the discipline for using linear and univariate rather than complex and multivariate theories, and for a naïve search for magic answers (reviewed in Clegg 1993). It is our contention that little has changed, and that uncertain meaning and normalization combine to create ideal conditions for dogma. Reinders' exposition of the various uses of meaning in our article and in different linguistic and historical traditions develops a vital but neglected topic in intellectual disability, which we consider in some detail. We conclude by arguing that developments require us to distance ourselves from the universality and commonality inherent to normalization, and create new ways to appreciate particularity and diversity.The gist of Reinders' complex argument appears to be that the problems we identify in managing bereavement in intellectual disability stem from a modernist understanding of meaning that is erroneous. Implicitly, those who eschew its pursuit demonstrate the greater wisdom, because neither dialogue nor activities such as reflection can generate meaning that is unattainable. If we understand his position correctly, he contrasts two principal understandings of meaning: comprehension and apprehension.Comprehension is the illusory modernist idea that humans are agents who make sense of themselves...

The traditional business of Aesthetics has been the study of the aesthetic experience and activity of mankind, in order to show what it is and how it can be distinguished from other experiences and activities. The assumption commonly made is that we ourselves, like others before us, have had a specifically aesthetic experience in the enjoyment of art or the beauty of nature, or have been engaged in the making of something unquestionably artistic. This basic assumption has been challenged recently (...) by I. A. Richards, who calls aesthetic experience “a phantom.” His view is shared by other contemporary philosophers, who also maintain that there is no appreciable difference between an aesthetic reaction and any other frame of mind, or between artistic behaviour and other forms of creative work. We can certainly appeal to experience for the support of a postulate usually taken for granted and say that most artists, authors, and ordinary people in fact regard their aesthetic experience as something entirely distinct from what they do or feel at other times. Analysis will show whether this common-sense opinion is illusory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Imitation, Violence, and ExchangeGirard and MaussPer Bjørnar Grande (bio)RECIPROCAL VIOLENCE AND THE DESIRE FOR WHAT THE OTHER DESIRESIn this article, I would like to draw attention to the potentially violent outcome of exchange interactions between individuals and groups. Both Girard and Mauss examine violence in a wider social and political process.1 According to Mauss, the smallest difference, such as a lack of reciprocity, may evoke a desire for retribution. (...) Understanding reactions when there is a lack of symmetry, real or illusory, can give us an important insight into the generative mechanisms behind violence. This is why traditional societies tried, often very successfully, to protect individuals through prohibitions and taboos. These prohibitions and taboos were directed against any kind of activity that could possibly result in violent rivalries among the population. The killing of adulterers, thieves, and foreigners can be seen as a way of ridding society of people perceived as having undesirable traits and ridding it of the potential imitation of their bad desires. In this way, a society's violence may function in a protective [End Page 221] and anti-mimetic way. The violence against transgressors is a kind of mimetic anti-mimesis, a way of telling people to follow the rules of society so that they will become mimetically immune to the forces that threaten society.Violent victimizing appears to fulfill a generative function by preventing transgressions, moral cleansing, and restoration of peace. At the same time, however, it bears (unconsciously for the participants) a similarity to what one wishes to expel, namely, the feared violence and negative influence of the person or persons who are victimized. Despite attempts to expel violent transgressions, the attempts themselves are quite similar to the violence they are trying to exorcise. Both Freud and Girard argue that those who conduct a rite of sacrifice are projecting onto the sacrificial victim qualities that reflect some of their own innermost concerns.2 Sacrificial violence, seen from a modern, nonsacrificial standpoint, is a kind of suicide. By killing the other, one also kills something in oneself.In demolishing the victim they are symbolically annihilating aspects of themselves. What is destroyed is destructiveness itself: the feelings of violence and hostility that lie behind attempts to carry out violent activities. Such feelings are antithetical to the ties of friendship that bond a community together, and feelings of violence towards one's peers and associates must be banished if a closely knit community—such as a tribal brotherhood, a spiritual fellowship, or a modern nation—is to survive.3Modern societies are full of these projections of one's own desires onto the other, which expose the modern variant of what is sacrifice, and which are often less physically but instead psychologically violent, yet still victimizing in their attitude of projecting. Terms such as "imitation," "identification," and "comparison" do not have to turn out to be violent—even when a great deal of competition is involved. In this respect, I disagree with some Girardians who claim that imitative desire must be violent and who look back to an insight going back to Heraclitus that violence is the source of all.4 The all-decisive factor is the gradual shift from competition to rivalry, from being allies to becoming enemies. The transition from being competitive friends to rivals comes as a result of imitation. Seen in this way, imitative desire is the generative force behind violence, the snake that turns friends and lovers into rivals.This Freudian act of projection resembles an act of doubling, an intense mimesis of the other that creates doubles. From a Girardian perspective, it is the clash of desire that leads to doubling, and later to violence.5 The imitation of each other's desires will sooner or later cause some kind of violence.6 This doubling does not only have to involve two people; it can be groups, even countries. [End Page 222] But the effect is always negative. Raymund Schwager explains it in the following terms:Whoever is desirous has to expect that the others will too. Whoever succumbs to rivalry arouses the same passion in others. Whoever resorts to violence is imitated in his or... (shrink)

We design a double-or-quits game to compare the speed of learning one’s specific ability with the speed of rising confidence as the task gets increasingly difficult. We find that people on average learn to be overconfident faster than they learn their true ability and we present an intuitive-Bayesian model of confidence which integrates confidence biases and learning. Uncertainty about one’s true ability to perform a task in isolation can be responsible for large and stable confidence biases, namely limited discrimination, the (...) hard–easy effect, the Dunning–Kruger effect, conservative learning from experience and the overprecision phenomenon if subjects act as Bayesian learners who rely only on sequentially perceived performance cues and contrarian illusory signals induced by doubt. Moreover, these biases are likely to persist since the Bayesian aggregation of past information consolidates the accumulation of errors and the perception of contrarian illusory signals generates conservatism and under-reaction to events. Taken together, these two features may explain why intuitive Bayesians make systematically wrong predictions of their own performance. (shrink)

A fair share of change problematics in organizations can be led back to the human factor. In earlier days the problem used to be that the worker was considered as a mechanical element, as ‘a pair of hands’ (Henry Ford). Nowadays we know that people want to be taken seriously and, if so, in general perform better. But when you concentrate on the worker’s sense of meaning for the sake of better achievements, do you really take him seriously? Or does (...) he get, be it in a subtle way, again enlisted in other man’s target schemes? The widespread cynicism about what happens in organizations, in spite of extensive Human Resource Management, and the high percentage of failing change trajectories call for a closer examination of man in organizations and his resistance. -/- For such an examination this thesis turns to the philosophy of Emmanuel Levinas, namely to his treatment of rationality. Rational thought according to Levinas has the merit of making the world lucid and controllable. But at the same time it strips things and people of their identity and incorporates them in a homogenized rational order. Illusory, but nonetheless oppressive. Rationality’s totalitarian character can provoke resistance and grief with people who are enlisted by it. This can lead to a shameful confrontation in which the thinker is being confronted with his victim’s resistance and sees himself and his thinking made questionable. By proceeding along this route, thinking can be brought to self-criticism and to revision of standpoints. -/- This description by Levinas of rational thinking shows similarity to what managers do in organizations. They make their business controllable, but at the same time with their planning and schemes they create a totalitarian straitjacket. This similarity suggests that also the reactions to imperialistic rationality from Levinas’ description ought to be found in organizations. Is it indeed possible to indicate there the kind of resistance and grief Levinas speaks about? Does that give rise to confrontations between managers and their co-workers who are supposed to subordinate to their schemes? Do managers then feel shame? And do those shameful confrontations consequently lead to self-reflection and change? -/- Desk research suggests that the above elements are partly to be found in the literature of management theory. Interviews with managers show that Levinas’ line of thought can also be found in its completeness within organizations. At the same time it becomes clear that becoming conscious of the elements of that line of thought – that rationality is all-conquering, that it provokes resistance, that that can lead to shame as well as to a new beginning – this is a difficult path to travel. The related experiences are easily forgotten and sometimes difficult to excavate. Translation of Levinas’ thinking into terms of management and organization can help us spot them where they play their role in organizations. (shrink)

This commentary argues that the “illusion” to which Wegner refers in The Illusion of Conscious Will is actually the illusion that our conscious experience of mentally causing certain behaviors explains the behavior in question: It is not the subjective experience itself that is illusory, but the implied causal explanation. The experience of “mental effort” is cited as another example of this sort of illusion. Another significant example is the experience that properties of the representation of our mental images are (...) responsible for certain patterns of behavior observed in mental imagery experiments. Examples include the increase in reaction time found when details are reported from smaller images or when attention is switched between different places and features (imagined as further apart than they are) within a single image. These examples illustrate the nature of the “illusion” involved: It is the illusion that certain observed regularities occur because of the content of the experience, as opposed to the converse – that experience has the content it does because of what the person figures out would happen in the imagined situation.

Linear mixed-effect models (LMMs) are being increasingly widely used in psychology to analyse multi-level research designs. This feature allows LMMs to address some of the problems identified by Speelman and McGann ( 2013 ) about the use of mean data, because they do not average across individual responses. However, recent guidelines for using LMM to analyse skewed reaction time (RT) data collected in many cognitive psychological studies recommend the application of non-linear transformations to satisfy assumptions of normality. Uncritical adoption (...) of this recommendation has important theoretical implications which can yield misleading conclusions. For example, Balota et al. ( 2013 ) showed that analyses of raw RT produced additive effects of word frequency and stimulus quality on word identification, which conflicted with the interactive effects observed in analyses of transformed RT. Generalized linear mixed-effect models (GLMM) provide a solution to this problem by satisfying normality assumptions without the need for transformation. This allows differences between individuals to be properly assessed, using the metric most appropriate to the researcher's theoretical context. We outline the major theoretical decisions involved in specifying a GLMM, and illustrate them by reanalysing Balota et al.'s datasets. We then consider the broader benefits of using GLMM to investigate individual differences. (shrink)

Biological reproduction is a material process of intertwined, recursive propagule generation and development, assuming that development produces simple life cycles. Most organisms, however, have more or less complex life cycles. Here, I attempt to reconcile recent articulations of a reproducer account with traditional approaches to complex life cycles by generalizing genetic demarcation criteria for life cycle generations in terms of the “scaffolded” development of hybrid reproducers. I argue that scaffolding provides a general method for identifying developmental bottlenecks and suggests in (...) turn a new way of understanding developmental reaction norms. (shrink)

Stories about corporate social responsibility have become very frequent over the past decade, and managers can no longer ignore their impact on firm value. In this paper, we investigate the extent and the determinants of the stock market’s reaction following ordinary news related to environmental, social and governance issues—the so-called ESG factors. To that purpose, we use an original database provided by Covalence EthicalQuote. Our empirical analysis is based on about 33,000 ESG news, targeting one hundred listed companies over (...) the period 2002–2010. On average, firms facing negative events experience a drop in their market value of 0.1%, whereas companies gain nothing on average from positive announcements. We find also that market participants are responsive to the media, but they do not react to firms’ press releases or to NGOs’ disclosures. Moreover, our results indicate that sector’s reputation mitigates the loss and that cultural proximity and lexical contents of ESG disclosures play a significant role in the magnitude of the impact.

Einstein regarded as one of the triumphs of his 1915 theory of gravity - the general theory of relativity - that it vindicated the action-reaction principle, while Newtonian mechanics as well as his 1905 special theory of relativity supposedly violated it. In this paper we examine why Einstein came to emphasise this position several years after the development of general relativity. Several key considerations are relevant to the story: the connection Einstein originally saw between Mach's analysis of inertia and (...) both the equivalence principle and the principle of general covariance, the waning of Mach's influence owing to de Sitter's 1917 results, and Einstein's detailed correspondence with Moritz Schlick in 1920.

Across the globe, radical conservative political forces and ideas are influencing and even transforming the landscape of international politics. Yet IR is remarkably ill-equipped to understand and engage these new challenges. Unlike political theory or domestic political analyses, conservatism has no distinctive place in the fields’ defining alternatives of realism, liberalism, Marxism, and constructivism. This paper seeks to provide a point of entry for such engagement by bringing together what may seem the most unlikely of partners: critical theory and the (...) New Right. Important parts of today’s New Right represent self-conscious appropriations of Critical themes and thinkers—turning them to self-declared “reactionary” ends. Developing outside the confines of the academy, these forms of thought have woven insights from across Critical theory into new and mobilizing forms of conservative ideology, seeking to link that ideology to social forces that play increasingly active roles in global politics. Our intention here is not to somehow blame Critical perspectives for the ideas of the New Right, either directly or by association. Rather, we seek to show how an engagement with Critical theory helps us understand the New Right, while also demonstrating some of the direct challenges the New Right poses for critical perspectives.

The search for the best wellness practice has promoted the development of devices integrating different technologies and guided meditation. However, the final effects on the electrical activity of the brain remain relatively sparse. Here, we have analyzed of the alpha and theta electroencephalographic oscillations during the realization of the arrest reaction when a chromotherapy session performed in a dedicated room [Rebalance device], with an ergonomic bed integrating pulsed-wave light stimulation, guided breathing, and body scan exercises. We demonstrated that the (...) PWL induced an evoked-related potential characterized by the N2-P3 components maximally recorded on the fronto-central areas and accompanied by an event-related synchronization of the delta–theta–alpha oscillations. The power of the alpha and theta oscillations was analyzed during repeated ARs testing realized along with the whole RB session. We showed that the power of the alpha and theta oscillations was significantly increased during the session in comparison to their values recorded before. Of the 14 participants, 11 and 6 showed a significant power increase of the alpha and theta oscillations, respectively. These increased powers were not observed in two different control groups who stayed passively outside or inside the RB room but without any type of stimulation. These preliminary results suggest that PWL chromotherapy and guided relaxation induce measurable electrical brain changes that could be beneficial under neuropsychiatric perspectives. (shrink)

We present an approach to understanding the origin of inertia involving the electromagnetic component of the quantum vacuum and propose this as a step toward an alternative to Mach's principle. Preliminary analysis of the momentum flux of the classical electromagnetic zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to acceleration attributed to inertia may be at least in part a force of opposition originating in the vacuum. This analysis avoids the ad hoc (...) modeling of particle-field interaction dynamics used previously by Haisch, Rueda, and Puthoff (Phys. Rev. A 49, 678, (1994)) to derive a similar result. This present approach is not dependent upon what happens at the particle point, but on how an external observer assesses the kinematical characteristics of the zero-point radiation impinging on the accelerated object. A relativistic form of the equation of motion results from the present analysis. Its manifestly covariant form yields a simple result that may be interpreted as a contribution to inertial mass. We note that our approach is related by the principle of equivalence to Sakharov's conjecture (Sov. Phys. Dokl. 12, 1040, (1968)) of a connection between Einstein action and the vacuum. The argument presented may thus be construed as a descendant of Sakharov's conjecture by which we attempt to attribute a mass-giving property to the electromagnetic component—and possibly other components—of the vacuum. In this view the physical momentum of an object is related to the radiative momentum flux of the vacuum instantaneously contained in the characteristic proper volume of the object. The interaction process between the accelerated object and the vacuum (akin to absorption or scattering of electromagnetic radiation) appears to generate a physical resistance (reaction force) to acceleration suggestive of what has been historically known as inertia.

This paper investigates the stochastically exponential stability of reaction-diffusion impulsive stochastic cellular neural networks. The reaction-diffusion pulse stochastic system model characterizes the complexity of practical engineering and brings about mathematical difficulties, too. However, the difficulties have been overcome by constructing a new contraction mapping and an appropriate distance on a product space which is guaranteed to be a complete space. This is the first time to employ the fixed point theorem to derive the stability criterion of reaction-diffusion (...) impulsive stochastic CNN with distributed time delays. Finally, an example is provided to illustrate the effectiveness of the proposed methods. (shrink)

Ludwik Fleck’s Genesis and Development of a Scientific Fact is an extended argument for the inclusion of social factors in the history and philosophy of science. Fleck uses the history of syphilis as his case study, which falls into two parts. In the first two chapters of his book, Fleck presents a history of the change of the concept of syphilis as a “carnal scourge with strong moralistic connotations” in the middle ages to the modern concept of syphilis as an (...) infectious disease (1979, 77). In the second part of the book, he presents a detailed account of the development of a serum test for syphilis, the Wasserman reaction. Fleck also argues that perception is theory-laden, for example, in his comparative study of anatomical drawings, and for the importance of social pressures on the development of science, for example, in his discussion of the rivalry between nations to first develop a cure for syphilis, as demanded by politicians (1979, 133 ff. and 68).

The goal of this paper is to critically examine the objections of John Locke’s contemporaries against the theory of substance or substratum. Locke argues in Essay that substratum is the bearer of the properties of a particular substance. Locke also claims that we have no knowledge of substratum. But Locke’s claim about our ignorance as to what substratum is, is contentious. That is, if we don’t know what substratum is, then what is the point of proposing it as a bearer (...) of properties? This question underlies the criticism Locke’s contemporaries raise against the notion of substratum. In section I, I lay out the context for Locke’s theory of substratum by pointing out his main motivation in proposing his theory. In section II, I give a brief analysis of the theory of substratum. In section III, I discuss the objections of Locke’s contemporaries against the theory of substratum.1 I focus on Edward Stillingfleet, Lee Henry, G. W. Leibniz and John Sergeant. In section IV, I conclude that there is no warrant to dismiss Locke’s theory of substance. (shrink)

A mechanistic explanation is a desired outcome in many studies of perception. Such explanations require discovering the processes that contribute to the realization of a perceptual phenomenon at different levels of information processing. The present analysis aims at investigating the obstacles to develop such mechanistic explanations and their potential solutions in the context of psychopathology. Geometric-Optical Illusions (GOIs) are among perceptual phenomena that have been studied to understand psychopathology in various clinical populations. In the present analysis, the GOIs will be (...) discussed as a methodological tool in the investigation of the mechanistic approach to understanding perception in such populations. I will argue that the fact that most such studies are mainly focused on the investigation of susceptibility to GOIs can only lead to classifying such phenomena or to reporting some correlations between different aspects of such phenomena with certain brain activities, without formulating a mechanistic explanation. The investigation of the variables that mediate perceptual phenomena at earlier stages of information processing is required for the formulation of such explanations. Thus, the objective of the present analysis is twofold: 1) showing how ignoring such variables have prevented the formulation of mechanistic explanations of responses to GOIs in clinical populations, such as schizophrenia and autism, 2) analyzing the methodological aspects of an effective approach in which a top-down guidance based on phenomenological insights (the first-person data) along with the insights provided by the existing theories help overcome obstacles in developing mechanistic explanations of GOIs.

This article discusses the reasons why illusory contours are likely to result from adaptive perceptual mechanisms that have evolved across species to promote behavioral success.

Behavioral intervention techniques leveraging reactive responses have gained popularity as tools for promoting ethical behavior. Choice architects, for example, design and present default opt-out options to nudge individuals into accepting preselected choices deemed beneficial to both the decision-maker and society. Such interventions can also employ mild financial incentives or affective triggers including joy, fear, empathy, social pressure, and reputational rewards. We argue, however, that ethical competence is achieved via reflection, and that heavy reliance on reactive behavioral interventions can undermine the (...) development of ethical competence over the long term. Specifically, drawbacks may occur through motivational displacement, dependency, moral crowding out, loss of personal autonomy, and reactance. We introduce complementary cognitive boosting techniques designed to stimulate reflective cognition, as a more promising long-term strategy for instilling ethical behavior. One such approach is the Moral Self-Awareness (MSA) motivational construct, which incrementally leads agents to increasing levels of ethical reflection. We explain why ethical boosting approaches present more edifying and durable alternatives to reactive behavioral interventions and offer suggestions for social and organizational policy. (shrink)

This article addresses the physical chemical processes underlying biological self-organisation by which a homogenous solution of reacting chemicals spontaneously self-organises. Theoreticians have predicted that self-organisation can arise from a coupling of reactive processes with molecular diffusion. In addition, the presence of an external field, such as gravity, at a critical moment early in the process may determine the morphology that subsequently develops. The formation, in-vitro, of microtubules, a constituent of the cellular skeleton, shows this type of behaviour. The preparations spontaneously (...) self-organise by reaction-diffusion and the morphology that develops depends upon the presence of gravity at a critical bifurcation time early in the process. Here, we present numerical simulations of a population of microtubules that reproduce this behaviour. Microtubules can grow from one end whilst shrinking from the other. The shrinking end leaves behind a chemical trail of high tubulin concentration. Neighbouring microtubules preferentially grow into these regions, whilst avoiding regions of low tubulin concentration. The chemical trails produced by individual microtubules thus activate and inhibit the formation of neighbouring microtubules and this progressively leads to self-organisation. Gravity acts by way of its directional interaction with the macroscopic density fluctuations present in the solution arising from microtubule disassembly. (shrink)

Studies of implicit learning have shown that individuals exposed to a rule-governed environment often learn to exploit 'rules' which describe the structural relationship between environmental events. While some authors have interpreted such demonstrations as evidence for functionally separate implicit learning systems, others have argued that the observed changes in performance result from explicit knowledge which has been inadequately assessed. In this paper we illustrate this issue by considering one commonly used implicit learning task, the Serial reaction time task, and (...) outline what we see as an important problem associated with each of the commonly used methods used to assess explicit knowledge. This is that each measure requires a form of response which is dependent on the subjects having some knowledge of the serial-order of the sequence. We argue that such methods, or more specifically their analyses, seriously underestimate other sources of knowledge, which may be available to subjects during their performance of the SRT task. In support of this argument we demonstrate that subjects' serial-order knowledge can, in principle, be independent of subjects' knowledge of the statistical structure of the sequence, and we propose an alternative method for analysing performance on the Generate task which avoids this problem.
