A hallmark of intelligent behavior is rationality – the disposition and ability to think analytically to make decisions that maximize expected utility or follow the laws of probability. However, the question remains as to whether rationality and intelligence are empirically distinct, as does the question of what cognitive mechanisms underlie individual differences in rationality. In a sample of 331 participants, we assessed the relationship between rationality and intelligence. There was a common ability underpinning performance on some, but not all, rationality (...) tests. Latent factors representing rationality and general intelligence were strongly correlated (r =.54), but their correlation fell well short of unity. Rationality correlated significantly with fluid intelligence (r =.56), working memory capacity (r =.44), and attention control (r =.49). Attention control fully accounted for the relationship between working memory capacity and rationality, and partially accounted for the relationship between fluid intelligence and rationality. We conclude by speculating about factors rationality tests may tap that other cognitive ability tests miss, and outline directions for further research. (shrink)

Humans are learning agents that acquire social group representations from experience. Here, we discuss how to construct artificial agents capable of this feat. One approach, based on deep reinforcement learning, allows the necessary representations to self-organize. This minimizes the need for hand-engineering, improving robustness and scalability. It also enables “virtual neuroscience” research on the learned representations.

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

What inductive biases must be incorporated into multi-agent artificial intelligence models to get them to capture high-fidelity imitation? We think very little is needed. In the right environments, both instrumental- and ritual-stance imitation can emerge from generic learning mechanisms operating on non-deliberative decision architectures. In this view, imitation emerges from trial-and-error learning and does not require explicit deliberation.

Researchers are often faced with attempting to estimate a correlation based on the aggregation of sample rs either from several samples or from repeated measures within a single sample. The usual approach is either to average the observed correlations or to average the Fisher’s z- transformed rs and to back-transform the average z value. This note describes a minimum-variance unbiased estimator for the situation that is superior to either approach and is also simple to compute.

The dorsal anterior cingulate cortex is a key node in the human salience network. It has been ascribed motor, pain-processing and affective functions. However, the dynamics of information flow in this complex region and how it responds to inputs remain unclear and are difficult to study using non-invasive electrophysiology. The area is targeted by neurosurgery to treat neuropathic pain. During deep brain stimulation surgery, we recorded local field potentials from this region in humans during a decision-making task requiring motor output. (...) We investigated the spatial and temporal distribution of information flow within the dACC. We demonstrate the existence of a distributed network within the anterior cingulate cortex where discrete nodes demonstrate directed communication following inputs. We show that this network anticipates and responds to the valence of feedback to actions. We further show that these network dynamics adapt following learning. Our results provide evidence for the integration of learning and the response to feedback in a key cognitive region. (shrink)

The E-Z Reader model (Reichle et al. 1998; 1999) provides a theoretical framework for understanding how word identification, visual processing, attention, and oculomotor control jointly determine when and where the eyes move during reading. In this article, we first review what is known about eye movements during reading. Then we provide an updated version of the model (E-Z Reader 7) and describe how it accounts for basic findings about eye movement control in reading. We then review several alternative models of (...) eye movement control in reading, discussing both their core assumptions and their theoretical scope. On the basis of this discussion, we conclude that E-Z Reader provides the most comprehensive account of eye movement control during reading. Finally, we provide a brief overview of what is known about the neural systems that support the various components of reading, and suggest how the cognitive constructs of our model might map onto this neural architecture. Key Words: attention; eye-movement control; E-Z Reader; fixations; lexical access; models; reading; regressions; saccades. (shrink)

Paradoxes evoke astonishment, confusion, and delight in the extraordinary. But that is not all: They point to fundamental problems of philosophy, mathematics, and the natural sciences. This volume presents a number of the most important paradoxes from an analytical-philosophical perspective. -/- German abstract: Paradoxien rufen Staunen, Verwirrung und die Lust am Außergewöhnlichen hervor. Aber nicht nur das: Es sind Paradoxien, die bis heute auf Grundprobleme der Philosophie, der Mathematik sowie der Naturwissenschaften hinweisen und uns zu revolutionären Lösungsvorschlägen herausfordern. -/- Einige (...) Paradoxien markieren dabei vielleicht sogar unüberwindbare Grenzen unseres Wissens. Dieser Band stellt eine Reihe der wichtigsten Paradoxien – Paradoxien der Wahrheit, des Infiniten, der Bestätigung, der Vagheit, der Quantenmechanik, der Zeit, des Visuellen und des Auditiven – sowie Überlegungen zu allgemeinen Lösungswegen aus einer analytisch-philosophischen Perspektive vor. Dabei richtet er sich an interessierte Einsteiger in die Thematik, ohne den Gegenstand dabei zu sehr zu verkürzen. (shrink)

The standard $\mathbb{U}(1)$ “gauge principle” or “gauge argument” produces an exact potential A=dλ and a vanishing field F=d 2 λ=0. Weyl (in Z. Phys. 56:330–352, 1929; Rice Inst. Pam. 16:280–295, 1929) has his own gauge argument, which is sketchy, archaic and hard to follow; but at least it produces an inexact potential A and a nonvanishing field F=dA≠0. I attempt a reconstruction.

Chinese readers' eye movements were simulated in the context of the E-Z Reader model, which was developed to account for the eye movements of readers of English. Despite obvious differences between English and Chinese, the model did a fairly good job of simulating the eye movements of Chinese readers. The successful simulation suggests that the control of eye movements in reading Chinese is similar to that in an alphabetic language such as English.

The issues the commentators have raised and which we address, include: the debate over how attention is allocated during reading; our distinction between early and late stages of lexical processing; our assumptions about saccadic programming; the determinants of skipping and refixations; and the role that higher-level linguistic processing may play in influencing eye movements during reading. In addition, we provide a discussion of model development and principles for evaluating and comparing models. Although we acknowledge that E-Z Reader is incomplete, we (...) maintain that it provides a good framework for systematically trying to understand how the cognitive, perceptual, and motor systems influence the eyes during reading.

In answering the question “who is the subject of music,” we argue that it is a subject of excess and emergence, and we rely on the definition and development of these terms by Žižek and Björk. Such a subject is movement and activity; it exceeds the experiences, objects, others and symbolic order that make it who it is; and it emerges through desire and drive, and resonance and animation. We open with a brief discussion of Žižek’s subject of excess, which (...) we then relate to his approach to subjectivity in music. After an analysis of Björk’s music, centered on the piece “Black Lake” and from a perspective informed by Žižek’s account of subjectivity, we shift our attention to Björk’s thoughts on music in order to find elements that allow for the development of a subject of emergence. While the elements of excess and emergence are present in both accounts of the subject, Žižek’s and Björk’s respective focus on one of these concepts allow us to develop a fuller picture of subjectivity, particularly but not exclusively as it is engaged with in musical activities.

Unlike most anthologies in aesthetics and the philosophy of art, the present selection does not try to collect representative extracts from the writings of most, or even many, important aestheticians throughout the ages. It aims for depth rather than width and tries to do as much justice as possible to those aestheticians which it does include, without bothering much about those left out. The result is really impressive. No less than 138 pages are devoted to Plato and Aristotle alone, where (...) the reader may find not only the usual passages from the Poetics and the Rhetoric but also relevant material from De Partibus Animalium and Politica. Such an anthology, so it seems, must be an opinionated one. Thus, while it contains some 70 pages of Dewey's Art as Experience, there is not a single line of Santayana in it. Although I disagree with the choice made in this case, I cannot but admire the courage it took to make it. Another surprise is the inclusion of the relatively obscure mediaeval thinker, Marsilio Ficino, in an anthology which excludes Baumgarten, Lessing, Burke, Schiller, Coleridge, Bosanquet and Alexander, to mention but few, and whose sole contemporary representative is Heidegger. The extracts from Ficino's commentary on Plato prove, however, to be highly interesting and relatively original, too. Thus, even if Ficino is not as great as some of the aestheticians not included in this volume, I, for one, would not regret this mark of personal, off-beat, taste. The last selection, Heidegger's "The Origin of the Work of Art," appearing for the first time in English translation, comes as special bonus to the reader. The editors' introductions to each selection are generally concise, precise, and very helpful. Sometimes, however, one may find an exception: in their introduction to the Heidegger translation, the editors characterize the Kehre as a "reversal... from the stress on anxiety, nothingness... to a stress on more affirmative moods." This is, to say the least, a grossly misleading remark, which is likely to confuse the student of the later Heidegger rather than help him.—E. M. Z. (shrink)

We investigate the problem of punctual (fully primitive recursive) presentability of algebraic structures up to primitive recursive and computable isomorphism. We show that for mono-unary structures and undirected graphs, if a structure is not punctually categorical then it has infinitely many punctually non-isomorphic punctual presentations. We also show that the punctual degrees of any computably almost rigid structure as well as the order ($$\mathbb {Z},<$$ Z, < ) are dense. Finally we characterise the Boolean algebras which have a punctually 1-decidable (...) presentation that is computably isomorphic to a 1-decidable presentation. (shrink)

Although the individual mandate was upheld and the Commerce Clause may have been cabined, the decision to strike down a significant element of the “Medicaid expansion” may prove to be the most significant aspect of the Supreme Court’s decision in NFIB v. Sebelius. Under the Affordable Care Act (ACA), States were required to extend Medicaid coverage to all individuals under the age of 65 with incomes below 133 percent of the poverty line, a new “essential health benefits” package was required (...) for all new Medicaid recipients, and the increased costs due to the expansion would be entirely covered by the Federal government through 2016, with the Federal payment gradually decreasing to a minimum of 90 percent of the total cost from the expanded coverage. The element found to be unconstitutional was §1396c of the ACA, which permitted the withdrawal of all Federal Medicaid funds from those States that did not comply with the ACA’s requirements for Medicaid expansion. The effect on access to health care may be significant: roughly half of those expected to gain coverage under the ACA were going to gain it through the Medicaid expansion; it is unclear how many States will choose to opt into that expansion in the absence of §1396c.1 Additionally, the argument offered by the Court to strike down that provision might be used to attack other federal programs—concerning transportation, social services, environmental protection, and others—that have a similar structure. This paper will demonstrate that the argument rests on a theoretical mistake concerning the relationships between coercion, compulsion, and political accountability and that, further, this mistake is not one legally forced upon the Court.

This article reviews the possible role of the universal basic income in the transformation of experience in gender and age perspectives. The universal basic income has been particularly hotly debated in recent decades. Regardless of the position, the common tone of the debates is the imperative “we must experiment.” Such a close interest in the universal basic income derives from the fact that it threatens to change the “generic” for humans situation of finiteness of resources and the need to work. (...) Thus, it is able to change the experience of what it means to be human. Since the universal basic income allows to separate labor from income, it is likely that its introduction will return value to the currently stigmatized or devalued types of labor, such as child care, elderly care or domestic work. It creates opportunities for experience redistribution in gender perspective: care and leaving, affective connection, and sensitivity could become the business of both parents, not just mothers. Another experience redistribution is possible in age perspective. Along with automation of labor, population ageing is a universal process that will sooner or later affect all the countries. Alarmist narratives that present this process as a threat and a problem now prevail. They are largely based on outdated ideas about old age and what it means to be old. However, in fact, ageing is the maturation of the population as a whole. With a proper re-evaluation of the meaning and significance of old age, the introduction of the universal basic income could create material conditions for the transfer of experience from the elderly to the younger – for the first time since traditional societies.

To figure out whether the main empirical question “Is our brain hardwired to believe in and produce God, or is our brain hardwired to perceive and experience God?” is answered, this paper presents systematic critical review of the positions, arguments and controversies of each side of the neuroscientific-theological debate and puts forward an integral view where the human is seen as a psycho-somatic entity consisting of the multiple levels and dimensions of human existence (physical, biological, psychological, and spiritual reality), allowing (...) consciousness/mind/spirit and brain/body/matter to be seen as different sides of the same phenomenon, neither reducible to each other. The emergence of a form of causation distinctive from physics where mental/conscious agency (a) is neither identical with nor reducible to brain processes and (b) does exert “downward” causal influence on brain plasticity and the various levels of brain functioning is discussed. This manuscript also discusses the role of cognitive processes in religious experience and outlines what can neuroscience offer for study of religious experience and what is the significance of this study for neuroscience, clinicians, theology and philosophy. A methodological shift from “explanation” to “description” of religious experience is suggested. This paper contributes to the ongoing discussion between theologians, cognitive psychologists and neuroscientists. (shrink)

Mandelstam’s criticism of the Rayleigh theory of the blue color of the sky (1907) and his polemic with M. Planck (1907–1908) did not become notable events in the history of physics. However, the method of their coverage in the Soviet and in the post-Soviet physics literature is remarkable. Most of Soviet physicists and historians of physics supported Mandelstam's point of view in his criticism of both Raleigh and Planck. The situation changed only at the beginning of the 21st century: in (...) the Russian literature the publications appeared emphasizing that in the Raleigh–Mandelstam and Planck–Mandelstam controversies Mandelstam was not right, Raleigh and Planck were closer to the truth. Which presumptions of this trend can be noted? This was patriotism of the scientific school peculiar to Mandelstam’s graduate students and the former graduate students, the patriotism connected with solidarity which helped Mandelstam’s community to survive in the Soviet totalitarian regime and in the totalitarian organization of science. This was also progressionism which was popular among academics and among men in the street. The phenomenon of common knowledge, mutual knowledge among the members of a scientific community should be taken under consideration. Common knowledge is connected with the non-thematized anonymous inclusion of the ideological terminology into scientific discourse. (shrink)

Leech et al.'s analysis adds to an emerging consensus of the role of priming in analogy-making. However, their model cannot scale up to adult-level performance because not all relations can be cast as functions. One-size-fits-all accounts cannot capture the richness of analogy. Proportional analogies and transitive inferences can be made by nonstructural mechanisms. Therefore, these tasks do not generalize to tasks that require structure mapping.

There has long been tension between bioethicists whose work focuses on classical philosophical inquiry and those who perform empirical studies on bioethical issues. While many have argued that empirical research merely illuminates current practices and cannot inform normative ethics, others assert that research-based work has significant implications for refining our ethical norms. In this essay, I present a novel construct for classifying empirical research in bioethics into four hierarchical categories: Lay of the Land, Ideal Versus Reality, Improving Care, and Changing (...) Ethical Norms. Through explaining these four categories and providing examples of publications in each stratum, I define how empirical research informs normative ethics. I conclude by demonstrating how philosophical inquiry and empirical research can work cooperatively to further normative ethics. (shrink)

In the Soviet scientific literature of 1920‒30 the concept of probability was holly debated. The frequency concept which was proposed by R. von Mises became popular among Soviet physicists belonging to the L.I. Mandelstam community. Landau and Lifshitz were also close to this concept in their famous course of theoretical physics. A.Khinchin, a mathematician who cooperated with Kolmogorov, opposed to the frequency conception. In this paper we try to demonstrate that the frequency position was connected with the anthropomorphous approach to (...) physics, whereas Khinchin’s positions implied the criticism of anthropomorphism and put forward the ideal of objective knowledge.
