The electron double-slit interference is re-examined from the point of view of temporal topos. Temporal topos (or t-topos) is an abstract algebraic (categorical) method using the theory of sheaves. A brief introduction to t-topos is given. When the structural foundation for describing particles is based on t-topos, the particle-wave duality of electron is a natural consequence. A presheaf associated with the electron represents both particle-like and wave-like properties depending upon whether an object in the site (t-site) is specified (...) (particle-like) or not (wave-like). It is shown that the localization of the electron at one of the slits is equivalent to choosing a particular object in the t-site and that the electron behaves as a wave when it passes through a double-slit because there are more than one object in the t-site. Also, the single-slit diffraction is interpreted as a result of the possibility of many different ways of factoring a morphism between two objects. (shrink)

The theory stating that oxidative stress is at the root of several diseases is extremely popular. However, so far, no antioxidant is recommended or offered by healthcare systems neither approved as therapy by regulatory agencies that base their decisions on evidence-based medicine. This is simply because, so far, despite many preclinical and clinical studies indicating a beneficial effect of antioxidants in many disease conditions, randomised clinical trials have failed to provide the evidence of efficacy required for drug approval. In (...) this review, we discuss the levels of evidence required to claim causality in preclinical research on OS, the weakness of the oversimplification associated with OS theory of disease and the importance of the narrative in its popularity. Finally, from a more translational perspective, we discuss the reasons why antioxidants acting by scavenging reactive oxygen species might not only prevent their detrimental effects but also interfere with essential signalling roles. We propose that ROS have a complex metabolism and are generated by different enzymes at diverse sites and with different timing. Aggregating this plurality of systems in a single theory of disease may not be the best way to develop new drugs, and future research may need to focus on specific oxygen-toxifying pathways rather than on non-specific ROS scavengers. Finally, similarly to what is nowadays required for clinical trials, we recommend making unpublished data available in repositories, as this will allow big data approaches or meta-analyses without the blinders of the publication bias.

It is argued that some elusive “entropic” characteristics of chemical bonds, e.g., bond multiplicities (orders), which connect the bonded atoms in molecules, can be probed using quantities and techniques of Information Theory (IT). This complementary perspective increases our insight and understanding of the molecular electronic structure. The specific IT tools for detecting effects of chemical bonds and predicting their entropic multiplicities in molecules are summarized. Alternative information densities, including measures of the local entropy deficiency or its displacement relative to (...) the system atomic promolecule, and the nonadditive Fisher information in the atomic orbital resolution(called contragradience) are used to diagnose the bonding patterns in illustrative diatomic and polyatomic molecules. The elements of the orbital communication theory of the chemical bond are briefly summarized and illustrated for the simplest case of the two-orbital model. The information-cascade perspective also suggests a novel, indirect mechanism of the orbital interactions in molecular systems, through “bridges” (orbital intermediates), in addition to the familiar direct chemical bonds realized through “space”, as a result of the orbital constructive interference in the subspace of the occupied molecular orbitals. Some implications of these two sources of chemical bonds in propellanes, π-electron systems and polymers are examined. The current–density concept associated with the wave-function phase is introduced and the relevant phase-continuity equation is discussed. For the first time, the quantum generalizations of the classical measures of the information content, functionals of the probability distribution alone, are introduced to distinguish systems with the same electron density, but differing in their current(phase) composition. The corresponding information/entropy sources are identified in the associated continuity equations. (shrink)

Walker's target article proposes a refinement of the well known two-stage model of memory formation to explain the positive effects of sleep on consolidation. After a first stage in which a labile memory representation is formed, a further stabilisation of the memory trace takes place in the second stage, which is dependent on (REM) sleep. Walker has refined the latter stage into a stage in which a consolidation-based enhancement occurs. It is not completely clear what consolidation-based enhancement implies and how (...) it can be dissociated from a stage for memory-stabilisation. A more serious consideration, however, is whether a second stage in memory consolidation that is solely dependent on sleep, is really necessary. The classical, passive, interference theory is able to explain adequately the findings related to the effects of sleep and memory, and can lead perhaps better to an understanding of the highly variable data in this field.

Spatial aspects of words are associated with their canonical locations in the real world. Yet little research has tested whether spatial associations denoted in language comprehension generalize to their corresponding images. We directly tested the spatial aspects of mental imagery in picture and word processing (Experiment 1). We also tested whether spatial representations of motion words produce similar perceptual-interference effects as demonstrated by object words (Experiment 2). Findings revealed that words denoting an upward spatial location produced slower responses to (...) targets appearing at the top of the display, whereas words denoting a downward spatial location produced slower responses to targets appearing at the bottom of the display. Perceptual-interference effects did not obtain for pictures or for words lacking a spatial relation. These findings provide greater empirical support for the perceptual-symbols system theory (Barsalou, 1999, 2008). (shrink)

We present a detailed process theory of the moment‐by‐moment working‐memory retrievals and associated control structure that subserve sentence comprehension. The theory is derived from the application of independently motivated principles of memory and cognitive skill to the specialized task of sentence parsing. The resulting theory construes sentence processing as a series of skilled associative memory retrievals modulated by similarity‐based interference and fluctuating activation. The cognitive principles are formalized in computational form in the Adaptive Control of (...) Thought–Rational (ACT–R) architecture, and our process model is realized in ACT–R. We present the results of 6 sets of simulations: 5 simulation sets provide quantitative accounts of the effects of length and structural interference on both unambiguous and garden‐path structures. A final simulation set provides a graded taxonomy of double center embeddings ranging from relatively easy to extremely difficult. The explanation of center‐embedding difficulty is a novel one that derives from the model' complete reliance on discriminating retrieval cues in the absence of an explicit representation of serial order information. All fits were obtained with only 1 free scaling parameter fixed across the simulations; all other parameters were ACT–R defaults. The modeling results support the hypothesis that fluctuating activation and similarity‐based interference are the key factors shaping working memory in sentence processing. We contrast the theory and empirical predictions with several related accounts of sentence‐processing complexity. (shrink)

Classical (Bayesian) probability (CP) theory has led to an influential research tradition for modeling cognitive processes. Cognitive scientists have been trained to work with CP principles for so long that it is hard even to imagine alternative ways to formalize probabilities. However, in physics, quantum probability (QP) theory has been the dominant probabilistic approach for nearly 100 years. Could QP theory provide us with any advantages in cognitive modeling as well? Note first that both CP and QP (...) theory share the fundamental assumption that it is possible to model cognition on the basis of formal, probabilistic principles. But why consider a QP approach? The answers are that (1) there are many well-established empirical findings (e.g., from the influential Tversky, Kahneman research tradition) that are hard to reconcile with CP principles; and (2) these same findings have natural and straightforward explanations with quantum principles. In QP theory, probabilistic assessment is often strongly context- and order-dependent, individual states can be superposition states (that are impossible to associate with specific values), and composite systems can be entangled (they cannot be decomposed into their subsystems). All these characteristics appear perplexing from a classical perspective. However, our thesis is that they provide a more accurate and powerful account of certain cognitive processes. We first introduce QP theory and illustrate its application with psychological examples. We then review empirical findings that motivate the use of quantum theory in cognitive theory, but also discuss ways in which QP and CP theories converge. Finally, we consider the implications of a QP theory approach to cognition for human rationality. (shrink)

It has often been claimed that without drastic conceptual innovations a genuine explanation of quantum interference effects and quantum randomness is impossible. This book concerns Bohmian mechanics, a simple particle theory that is a counterexample to such claims. The gentle introduction and other contributions collected here show how the phenomena of non-relativistic quantum mechanics, from Heisenberg's uncertainty principle to non-commuting observables, emerge from the Bohmian motion of particles, the natural particle motion associated with Schrödinger's equation. This book will (...) be of value to all students and researchers in physics with an interest in the meaning of quantum theory as well as to philosophers of science. (shrink)

Modern mainstream ethical theories with its overemphasis on autonomy and non-interference have failed to adequately respond to contemporary social problems. A new ethical perspective is very much needed. Thanks to Carol Gilligan's 1982 groundbreaking work, 'In a Different Voice' , we now not only have virtue and communitarian ethicists, but also a group of feminist philosophers, charting a new direction for ethics that tempers modern ethics' obsession with autonomy, contractual rights, and abstract rules. Nel Noddings, in her 'Caring: A (...) Feminine Approach to Ethics and Moral Education', further contributed to this important discussion. In this work, Noddings proposes a new kind of moral ideal. She calls it "caring." Noddings defines "caring," as a direct, felt concern and action from the one-caring toward the well-being of the cared-for. In other words, care is a state of mental engrossment and motivational displacement that impels caring actions for the happiness of the cared-for and it transcends any rule-bound moral judgment. A caring attitude is best manifest in the spontaneous emotive bond of love between a mother and a child. This human relation of unscrutinized maternal love and care should be the model of ethics. Noddings's theory evokes a vigorous debate concerning whether or not the model can withstand rigorous philosophical scrutiny as a stand-alone ethical theory. This paper first discusses the strengths and weaknesses of a pure care ethics. Secondly, it demonstrates why both the Kantian and the Aristotelian attempts are unsatisfactory, and it offers a Confucian solution to the problems of care ethics. It argues that notwithstanding gender-oppressive practices that are at times associated with Confucianism, Confucian ethics of 'ren' (humaneness) is both more compatible with care ethics and is better equipped with conceptual resources than Kantian liberalism or Aristotelian virtue ethics to handle the moral predicament of the postmodern world. The paper demonstrates that care is an inherent element of Confucian 'ren' but that 'ren' is more than Noddings's care. It examines three essential principles that can be extracted from philosophical classical Confucianism: (1) an affectionate and particularistic approach to persons, (2) the mutual conditioning of the two prominent Confucian virtues -- humaneness (ren) and ritual propriety (li), and (3) the inseparability of the familial and the political self. The last section of the paper applies Confucian care ethics to concrete cases such as the geriatric care crisis and the problem of poverty. (shrink)

The Joint International Conference on Logic Programming, sponsored by the Association for Logic Programming, is a major forum for presentations of research, applications, and implementations in this important area of computer science.

Previous studies using the dot-perspective task postulated that people automatically take into account others' perspective even when it prevents them from achieving their own goals. This human ability may be of key importance for the ascription of mental states and social interactions. The cognitive and emotional determinants of automatic perspective taking is still matter of debate. To address this issue, we examined the performance in the Samson et al. APT task in 91 healthy adults who underwent a detailed neuropsychological testing (...) including assessment of their general intelligence, attention and impulsivity, alexithymia, and measures of affective empathy and explicit theory of mind. Univariate and multiple linear regression models were used to explore the association between mean reaction times in the APT task, and the CPT-II parameters, WAIS global score, TAS, and GeSoCS and mini-SEA scores. Only the CPT-II parameters were significantly associated with the mean reaction times. Increased omissions, commissions, and detectability as well as hit reaction time standard error in CPT-II were all related to worse performances both in Self and Other conditions. The mean number of errors was negatively associated with the GeSoCS score. Among the variables studied, only CPT-II parameters had a significant impact on egocentric and altercentric interference. Neither global intelligence nor alexithymia have an effect on dot-perspective task performance. The present findings suggest that people with lower attentional resources and increased impulsivity display worse performances in the APT task and are less responsive to both egocentric and altercentric interference.

This article, addressed to Yoga Therapists, sorts out the historical roots of our idea of Yoga, elucidates the colonial interference and distortion of Yoga, and shows that trauma and therapy are the primary focus of Yoga. However, unlike most philosophies of therapy, Yoga's solution is primarily moral philosophical---Yoga itself being a basic ethical theory, in addition to Virtue Theory, Consequentialism and Deontology. This article goes some way to elucidating that it is quite ironic (and absurd) that many (...) feel the need to bring being “trauma-informed” into the title of Yoga education. That’s like the vacuous “chai tea” moniker (“chai” being the Hindi word for tea). Decolonizing our understanding of Yoga involves retrieving the original theory as the primary explanation of the topic, which allows us to understand how various activities, called "yoga," can be ways of practicing the moral philosophy of Yoga. The idea that "yoga" means many things and projects relies upon a contra logical methodology of interpretation which violates constraints of basic reasoning. Putting aside interpretation for explication is part of critical thinking but also our own self therapy.

A two-body quantum correlation is calculated for a particle reflecting from a moving mirror. Correlated interference results when the incident and reflected particle substates and their associated mirror substates overlap. Using the Copenhagen interpretation of measurement, an asynchronous joint probability density, which is a function both of the different positions and different times at which the particle and mirror are measured, is derived assuming that no interaction occurs between each measurement. Measurement of the particle first, in the correlated (...) class='Hi'>interference region, results in a splitting of the mirror substate into ones which have and have not reflected the particle. An analog of the interference from the Doppler effect for only measurements of the particle, in this two-body system, is shown to be a consequence of the asynchronous measurement. The simplification obtained for a microscopic particle reflecting from a mesoscopic or macroscopic mirror is used to illustrate asynchronous correlation interferometry. In this case, the small displacement between these mirror states can yield negligible environmental decoherence times. In addition, interference of these mirror states does not vanish in the limit of large mirror mass due to the small momentum exchange in reflecting a microscopic particle. (shrink)

Subtle bodily sensations such as itching or fluttering that occur in the absence of any external trigger may serve to locate the spatial boundaries of the body. They may constitute the normal counterpart of extreme conditions in which body-related hallucinations and perceptual aberrations are experienced. Previous investigations have suggested that situations in which the body is spontaneously experienced as being deformed are related to the ability to perform own-body transformations, i.e., mental rotations of the body requiring disembodiment. We therefore decided (...) to consider whether the perception of SPS might relate to embodiment as assessed through the ability to perform own-body transformations and schizotypal traits, since high degrees of schizotypy in the general population have been associated with more vivid perceptions and aberrant perceptual experiences. Then participants completed a standard SPS task. Our analysis revealed that the slower the response time in the OBT task, the more frequent the perception of SPS. This suggests that difficulties in disembodying and mentally transforming one’s own body facilitate feeling oneself. Furthermore, a greater number of correct responses in the OBT task was associated with less frequent perception of SPS. This suggests that finding it easier to disembody and perform mental own-body transformations interferes with the ability to sense oneself. The results also show that higher schizotypal traits, as assessed through the SPQ, are associated with more frequent perception of SPS. Taken together, these results provide a coherent picture and suggest that embodiment is required in order to correctly feel oneself, as expressed through the perception of SPS. The ability to easily experience disembodiment reduces the sense of feeling oneself, and proneness to schizotypal traits produces body misperceptions that enhance and amplify this feeling. The results are discussed in the light of current knowledge and theories about body representations, taking into account attention and interoception as factors that influence body awareness. We offer explanations for perceptual aberrations, body-related delusions, and hallucinations based on misperceived or misinterpreted SPS, and we discuss possible mechanisms that may contribute to feeling and misperceiving oneself.

Philosophy and Memory Traces defends two theories of autobiographical memory. One is a bewildering historical view of memories as dynamic patterns in fleeting animal spirits, nervous fluids which rummaged through the pores of brain and body. The other is new connectionism, in which memories are 'stored' only superpositionally, and reconstructed rather than reproduced. Both models, argues John Sutton, depart from static archival metaphors by employing distributed representation, which brings interference and confusion between memory traces. Both raise urgent issues about (...) control of the personal past, and about relations between self and body. Sutton demonstrates the role of bizarre body fluids in moral physiology, as philosophers from Descartes and Locke to Coleridge struggled to control their own innards and impose cognitive discipline on 'the phantasmal chaos of association'. Going on to defend connectionism against Fodor and critics of passive mental representations, he shows how problems of the self are implicated in cognitive science. (shrink)

In this article, the author aims to demonstrate how Agamben’s concept of Homo Sacer is ideally epitomized by a soldier in war. A soldier in war holds a peculiar position, as killing of soldiers is considered neither illegal by laws nor immoral by ethics, and so a soldier is not considered to be legally or morally “guilty” in the usual sense of the word if he or she kills another soldier in war. The author analyzes the notion of Homo Sacer (...) – a figure representing a human that can be killed without the killer being punished, but at the same time someone who cannot be sacrificed – and further demonstrates that a soldier in war can be said to hold precisely such a status. The reason why a soldier cannot be sacrificed resides in the fact that he has already been “sacrificed to war” by his own society, in exchange for the safety of all other members of society. Perceiving a soldier as Homo Sacer provides a novel explanation and an additional argument for the moral symmetry of combatants, one of the pillars of non-revisionist Just War Theory, as all soldiers can be understood as persons sacrificed by their own societies.

Philosophy and Memory Traces, the book to which this is the preface, defends two theories of autobiographical memory. One is a bewildering historical view of memories as dynamic patterns in fleeting animal spirits, nervous fluids which rummaged through the pores of brain and body. The other is new connectionism, in which memories are ‘stored’ only superpositionally, and are reconstructed rather than reproduced. Both models depart from static archival metaphors by employing distributed representation, which brings interference and confusion between memory (...) traces. Both raise urgent issues about control of the personal past, and about relations between self and body. The book’s historical argument is anchored by a reinterpretation of Descartes’ dynamic physiology of memory and strange philosophy of the body. English critics of Descartes’ view of memories as motions complained that mechanistic neurophilosophy could not guarantee order in memory, and instead sought techniques for controlling the brain. In a new account of 18th-century philosophers’ fears of confusion in remembering, the author demonstrates the role of bizarre body fluids in moral physiology, as philosophers from Locke to Reid and Coleridge struggled to control their own innards and impose cognitive discipline on ‘the phantasmal chaos of association’. Finally, in a defence of connectionism against Jerry Fodor and against phenomenological and Wittgensteinian critics of passive mental representations, the author shows how problems of the self are implicated in contemporary sciences of mind. The book is an experiment in historical cognitive science, based on a belief that the interdisciplinary study of memory can exemplify the simultaneous attention to brain, body, and culture towards which psychological sciences must aim.

The processes mediating dynamic and flexible responding to rapidly changing task-environments are not well understood. In the present research we employ a Stroop procedure to clarify the contribution of context-sensitive control processes to online performance. In prior work Stroop interference varied as a function of probe location context, with larger Stroop interference occurring for contexts associated with a high proportion of congruent items [Crump, M. J., Gong, Z., & Milliken, B. . The context-specific proportion congruent stroop effect: location (...) as a contextual cue. Psychonomic Bulletin & Review, 13, 316–321.] Here, we demonstrate that this effect does not depend on awareness of the context manipulation, but that it can depend on attention to the predictive context dimension, and on the relative salience of the target and predictive context dimensions. We discuss the implications of our results for current theories of cognitive control. (shrink)

Recently a new attempt to go beyond quantum mechanics (QM) was presented in the form of so called prequantum classical statistical field theory (PCSFT). Its main experimental prediction is violation of Born’s rule which provides only an approximative description of real probabilities. We expect that it will be possible to design numerous experiments demonstrating violation of Born’s rule. Moreover, recently the first experimental evidence of violation was found in the triple slit interference experiment, see Sinha, et al. (Foundations (...) of Probability and Physics-5. American Institute of Physics, Ser. Conference Proceedings, vol. 1101, pp. 200–207, 2009). Although this experimental test was motivated by another prequantum model, it can be definitely considered as at least preliminary confirmation of the main prediction of PCSFT. In our approach quantum particles are just symbolic representations of “prequantum random fields,” e.g., “electron-field” or “neutron-field”; photon is associated with classical random electromagnetic field. Such prequantum fields fluctuate on time and space scales which are essentially finer than scales of QM, cf. ’t Hooft’s attempt to go beyond QM (see ’t Hooft arXiv:hep-th/0105105, 2001; arXiv:quant-ph/0212095, 2002; arXiv:quant-ph/0701097, 2007). In this paper we elaborate a detection model in the PCSFT-framework. In this model classical random fields (corresponding to “quantum particles”) interact with detectors inducing probabilities which match with Born’s rule only approximately. Thus QM arises from PCSFT as an approximative theory. New tests of violation of Born’s rule are proposed. (shrink)

A conservation principles tell us that some quantity, quality, or aspect remains constant through change. Such principles appear already in ancient and medieval natural philosophy. In one important strand of Greek cosmology, the rotatory motion of the celestial orbs is eternal and immutable. In optics, from at least the time of Euclid, the angle of reflection is equal to the angle of incidence when a ray of light is reflected. According to some versions of the medieval impetus theory of (...) motion, impetus remains in a projected body (and the associated motion persists) permanently unless the body is subject to outside interference. These examples could be multiplied. But it was in the seventeenth century that conservation principles began to play an absolutely central role in scientific theories. Each of Galileo Galilei, René Descartes, Christiaan Huygens, Gottfried Leibniz, and Isaac Newton founded his approach to physics upon the principle of inertia—that unless interfered with a body will undergo uniform rectilinear motion. A multitude of other conservation principles gained currency during the seventeenth century—some still with us, some long ago left behind. Descartes provides an interesting example of an author who attempted to derive all of his physical principles from conservation laws (Principles of Philosophy, see especially articles 36 to 42 of Part II). Descartes believed that the principles of his physics could be derived from the immutability of God, supplemented only by very weak assumptions about the existence of change in the world. He claims, in fact, that we ought to postulate the strongest conservation laws consistent with such change. These include. (shrink)

This chapter challenges the common claim that vicious forms of argumentative practice, like interpersonal arrogance and discursive polarisation, are caused by martial metaphors, such as ARGUMENT AS WAR. I argue that the problem isn’t the metaphor, but our wider practices of metaphorising and the ways they are deformed by invidious cultural biases and prejudices. Drawing on feminist argumentation theory, I argue that misogynistic cultures distort practices of metaphorising in two ways. First, they spotlight some associations between the martial and (...) argumentative domains while occluding others, resulting in a sort of myopia. Second, those cultures interfere with a phenomenon I label normative isomorphism – the capacity of some structural metaphors to enable (and often encourage) a transfer of normative chracater traits from the source domain to the target domain. Crucially, the normative status of character trait often changes across domains—traits that are virtuous in the martial domain are often vicious in the argumentative domain, and vice versa. Sexist myopia tends to deform practices of metaphorising by interfering with normative isomorphism by privileging the transfer across domains of traits that recapitulate invidious cultural constructions of masculinity in terms of aggression, domination, and violence. Basically, the problem isn’t the metaphors, but the cultures. (shrink)

This paper presents two studies on the development and validation of a ten-item scale of epistemic vice and the relationship between epistemic vice and misinformation and fake news. Epistemic vices have been defined as character traits that interfere with acquiring, maintaining, and transmitting knowledge. Examples of epistemic vice are gullibility and indifference to knowledge. It has been hypothesized that epistemically vicious people are especially susceptible to misinformation and conspiracy theories. We conducted one exploratory and one confirmatory observational survey study on (...) Amazon Mechanical Turk among people living in the United States (total _N_ = 1737). We show that two psychological traits underlie the range of epistemic vices that we investigated: indifference to truth and rigidity. Indifference manifests itself in a lack of motivation to find the truth. Rigidity manifests itself in being insensitive to evidence. We develop a scale to measure epistemic vice with the subscales indifference and rigidity. The Epistemic Vice Scale is internally consistent; has good convergent, divergent, and discriminant validity; and is strongly associated with the endorsement of misinformation and conspiracy theories. Epistemic vice explains additional variance in the endorsement of misinformation and conspiracy theories over and above demographic and related psychological concepts and shows medium to large effect sizes across outcome measures. We demonstrate that epistemic vice differs from existing psychological constructs, and show that the scale can explain individual differences in dealing with misinformation and conspiracy theories. We conclude that epistemic vice might contribute to “postfactive” ways of thinking. (shrink)

The statistical aspects of quantum explanation are intrinsic to quantum physics; individual quantum events are created in the interactions associated with observation and are not describable by predictive theory. The superposition principle shows the essential difference between quantum and non-quantum physics, and the principle is exemplified in the classic single-photon two-slit interference experiment. Recently Mandel and Pfleegor have done an experiment somewhat similar to the optical single-photon experiment but with two independently operated lasers; interference is obtained even (...) with beam intensity so small that only one photon is in the apparatus at a time. The result can be understood in terms of the superposition of states; or, in terms of the Uncertainty Principle, which is found to forbid the determination of which of the two lasers is the source of a given photon (if conditions for interference are to obtain). The Mandel-Pfleegor experiment gives a physical argument against the continuous localization of a photon that is assumed in the hidden variable theories and therefore gives further support for the generally accepted view that an observed entity (observed state) is created in the observation event. This aspect of quantum physics implies a subjectivism on the level of individual quantum-level occurrences, since there is in quantum theory no basis for asserting the existence of the event independently of observation of it. Extension of this subjectivism to large scale, non-quantum phenomena falls within the principles of quantum theory; counter considerations that argue against such an extension are noted. (shrink)

We show that local realism applied to states characterized by a single quantum equally and coherently shared between a number of qubits (so-called W states) produces predictions incompatible with quantum theory. The origin of this incompatibility is shown to originate from the destructive interference of amplitude probabilities associated with nonlocal states, a phenomenon that has no classical analog.

Current views of the control of complex, purposeful movements acknowledge that organizational processes must reconcile multiple concerns. The central priority is of course accomplishing the actor's goal. But in specifying the manner in which this occurs, the action plan must accommodate such factors as the interaction of mechanical forces associated with the motion of a multilinked system (classical mechanics) and, in many cases, intrinsic bias toward preferred movement patterns, characterized by so‐called “coordination dynamics.” The most familiar example of the latter (...) is the symmetry constraint, where spatial trajectories and/or temporal landmarks (e.g., reversal points) of concurrentlymoving body segments (limbs, digits, etc.) exhibit mutual attraction. The natural coordination tendencies that emerge through these constraints can facilitate or hinder motor control, depending on the degree of congruency with the desired movement pattern. Motor control theorists have long recognized the role of classical mechanics in theories of movement organization, but an appreciation of the importance of intrinsic interlimb bias has been gained only recently.Although detailed descriptions of temporal coordination dynamics have been provided, systematic attempts to identify additional salient dimensions of interlimb constraint have been lacking. We develop and implement here a novel method for examining this problem by exploiting two robust principles of psychomotor behavior, the symmetry constraint and the Two‐Thirds Power Law. Empirical evidence is provided that the relative spatial patterns of concurrently moving limbs are naturally constrained in much the same manner as previously identified temporal constraints and, further, that apparent velocity interference is an indirect, secondary consequence of primary spatial assimilation. The theoretical implications of spatial interference are elaborated with respect to movement organization and motor learning. The need to carefully consider the appropriate dimensions with which to characterize coordination dynamics is also discussed. (shrink)

The classical liberal doctrine of free expression asserts the priority of speech as an extension of the freedom of thought. Yet its critics argue that freedom of expression, itself, demands the suppression of the so-called “silencing speech” of racists, sexists, and so on, as a threat to the equal expressive rights of others. This essay argues that the claim to free expression must be distinguished from claims to equal speech. The former asserts an equal right to express one’s thoughts without (...) interference; the latter the right to address others, and to receive a hearing and consideration from them, in turn. I explore the theory of equal speech in light of the ancient Athenian practice of isegoria and argue that the equality demanded is not distributive but relational: an equal speaker’s voice should be counted as “on a par” with others. This ideal better captures critics’ concerns about silencing speech than do their appeals to free expression. Insofar as epistemic and status-harms provide grounds for the suppression and exclusion of some speech and speakers, the ideal of equal speech is more closely connected with the freedom of association than of thought. Noticing this draws attention to the continuing—and potentially problematic—importance of exclusion in constituting effective sites of equal speech today. (shrink)

This book focuses on the challenges associated with effective choice over time. In particular, it considers the challenges raised by cyclic preferences and by incomplete preferences, both of which interfere with the agent's neatly ordering her options, and which make the agent susceptible to self-defeating patterns of choice in which the agent is drawn into taking each of a series of steps that collectively lead her to a result that she deems unacceptable. The book's guiding questions are the following: What (...) is an agent to do if she finds herself with cyclic preferences or with incomplete preferences? Is an agent or group of agents with such preferences necessarily irrational? It is argued that the answer to the latter question is "no"; rationality does not invariably prohibit disorderly preferences, but it does (to get back to the first question) prompt us to proceed with caution and with a readiness to show restraint, based on an awareness of larger dynamics, when our preferences are disorderly. Theories of rational choice often dismiss or abstract away from the sorts of disorderly preferences at issue here. They assume that rational agents can and should have neat preferences over their options; but this assumption is problematic. Rationality can validate certain disorderly preference structures while also protecting us from self-defeating patterns of choice. Rationality can thus handle quite a lot of messiness, which is important, since rationality wouldn't be all that helpful if, whenever messiness threatened, we could not turn to it for guidance.

We present a novel variant of decision making based on the mathematical theory of separable Hilbert spaces. This mathematical structure captures the effect of superposition of composite prospects, including many incorporated intentions, which allows us to describe a variety of interesting fallacies and anomalies that have been reported to particularize the decision making of real human beings. The theory characterizes entangled decision making, non-commutativity of subsequent decisions, and intention interference. We demonstrate how the violation of the Savage’s (...) sure-thing principle, known as the disjunction effect, can be explained quantitatively as a result of the interference of intentions, when making decisions under uncertainty. The disjunction effects, observed in experiments, are accurately predicted using a theorem on interference alternation that we derive, which connects aversion-to-uncertainty to the appearance of negative interference terms suppressing the probability of actions. The conjunction fallacy is also explained by the presence of the interference terms. A series of experiments are analyzed and shown to be in excellent agreement with a priori evaluation of interference effects. The conjunction fallacy is also shown to be a sufficient condition for the disjunction effect, and novel experiments testing the combined interplay between the two effects are suggested. (shrink)

Achievement flow involves total absorption in an activity, high concentration without effort and merging of thought and action. The authors propose that achievement flow is facilitated by dynamic alternatives between low positive affect (“seeing difficulty”) and high positive affect (“mastering difficulty”). Consistent with this hypothesis, three studies showed that traits associated with reduced positive affect (avoidant adult attachment, schizoid-like personality style, introversion) and traits supportive of restoring positive affect (mastery orientation) predicted achievement flow, as assessed with a new operant motive (...) test (OMT). Achievement flow motives were further found to be associated with flow experiences in achievement tasks (Study 1), intrinsic motivation in an academic context (Study 2), and volitional facilitation as assessed by removal of Stroop interference after experimentally induced difficulty and positive affect (Study 3). These findings offer converging evidence that flow experiences arise from dynamic changes in positive affect. (shrink)

In light of a gap found by Krupiński, we give a new proof of associativity for the Morley product of invariant measures in NIP theories.
