Systems for color naming across languages have been a fascinating topic for decades. Zaslavsky and colleagues challenge Gibson's argument that color names are shaped by patterns of communicative need. Using an information‐theoretic analysis, they show that color naming is shaped by both perceptual structure (as is usually argued) but also by communication need.

Learning to understand a single causal system can be an achievement, but humans must learn about multiple causal systems over the course of a lifetime. We present a hierarchical Bayesian framework that helps to explain how learning about several causal systems can accelerate learning about systems that are subsequently encountered. Given experience with a set of objects, our framework learns a causal model for each object and a causal schema that captures commonalities among these causal models. The schema organizes the (...) objects into categories and specifies the causal powers and characteristic features of these categories and the characteristic causal interactions between categories. A schema of this kind allows causal models for subsequent objects to be rapidly learned, and we explore this accelerated learning in four experiments. Our results confirm that humans learn rapidly about the causal powers of novel objects, and we show that our framework accounts better for our data than alternative models of causal learning.

Rogers & McClelland (R&M) criticize models that rely on structured representations such as categories, taxonomic hierarchies, and schemata, but we suggest that structured models can account for many of the phenomena that they describe. Structured approaches and parallel distributed processing (PDP) approaches operate at different levels of analysis, and may ultimately be compatible, but structured models seem more likely to offer immediate insight into many of the issues that R&M discuss.

In lieu of an abstract, here is a brief excerpt of the content:"General Rules" in Hume's Treatise THOMAS K. HEARN, JR. IT COULDBE CONFIDENTLYASSERTED in 1925 that Hume was "no longer a living figure." x Stuart Hampshire records that when he began his philosophy studies in 1933, Hume's conclusions were regarded at Oxford as "extravagances of scepticism which no one could seriously accept." 2 That virtually no Anglo-American philosopher would now share such opinions about Hume testifies not only to the (...) general change in the philosophical climate but, in addition, it reflects a transformation which has occurred in the interpretation of Hume's philosophy. In eitecting this transformation.much credit is due to the work of Norman Kemp Smith. Kemp Smith argued that preoccupation with Hume's empiricist heritage and his scepticism had blinded scholars to the fundamentally constructive intent of his philosophy, and, indeed, that only from the perspective of his positive achievement was it possible to grasp the nature and significance of Humean scepticism. This paper, in keeping with the basic orientation of Kemp Smith, sets out a central feature in the attempt to describe and assess Hume's constructive, nonsceptical point of view: Hume attributes to general rules "a mighty influence on our actions and understanding..." (374).4 This paper examines the Treatise to show that this was not just a casual comment. To discuss the "influence" of general rules requires an examination of their character and the various aspects of "action and understanding " in which such rules function. The thesis to be developed can be stated briefly. In Book I Hume introduces two sorts of general rules which must be distinguished carefully. One type of rule describes a propensity of the imagination to extend the scope This research was supported by a grant from the National Foundation on the Arts and Humanities. x Charles W. Hendcl, Studies in the Philosophy of David Hume (New York, 1963), p. 20. (First published in 1925.) For Professor Hendel's later comments on this statement, see pp. xxi ft. "Hume's Place in Philosophy" in David Hume, ed. D. F. Pears (London, 1963), p. 3. a Proper stress is due here to the phrase "basic orientation." There is much about Kemp Smith's understanding of Hume which is mistaken in my view. 9 The page references in parentheses refer to the Svlby-Bigge edition of A Treatise o/ Human Nature (Oxford, 1888). [4o5] 406 HISTORY OF PHILOSOPHY of judgments formed in one set of circumstances to other resembling but non-identical circumstances. The other type of general rule, the discussion of which largely occupies this paper, functions to correct certain natural propensities which result in erroneous belief or action if permitted to operate unchecked. The same pattern, a natural tendency requiring correction by general rules, is exhibited in all three books of the Treatise, and can be said to represent one of the basic ingredients in Hume's account of human nature and experience. It is somewhat surprising that in a book which patiently discusses almost evcxy theme in the Treatise, Kemp Smith's study contains no discussion at all of rules. This is the more puzzling as Kemp Smith clearly recognized that by reflection the understanding supplies principles which are normative for the interpretation of experience.5 Our aim in this study is to discuss what for Hume these principles are, and, as far as possible, how they fit into the Humean account of human nature. A fuller understanding of the nature and function of such reflective principles is required to spare Kemp Smith's interpretation from a seeming inconsistency. This apparent inconsistency arises because Kemp Smith takes the slavery of reason to the passions as the "key" to his understanding of Hume, but then develops the view that for Hume reason/s a passion, in Hume's words, "a wonderful and unintelligible instinct." (179)6 The inconsistency disappears when it is recognized that Kemp Smith's account of Hume requires a more subtle and complex understanding of the role of reason than that suggested by the emphasis on the "slavery of reason" especially in the early parts of the book. This study represents a way of supplying the broader and more const,ructive understanding of reason which... (shrink)

This paper reports laboratory data for games that are played only once. These games span the standard categories: static and dynamic games with complete and incomplete information. For each game, the treasure is a treatment in which behavior conforms nicely to predictions of the Nash equilibrium or relevant refinement. In each case, however, a change in the payoff structure produces a large inconsistency between theoretical predictions and observed behavior. These contradictions are generally consistent with simple intuition based on the interaction (...) of payoff asymmetries and noisy introspection about others’ decisions. (shrink)

If Bayesian Fundamentalism existed, Jones & Love's (J&L's) arguments would provide a necessary corrective. But it does not. Bayesian cognitive science is deeply concerned with characterizing algorithms and representations, and, ultimately, implementations in neural circuits; it pays close attention to environmental structure and the constraints of behavioral data, when available; and it rigorously compares multiple models, both within and across papers. J&L's recommendation of Bayesian Enlightenment corresponds to past, present, and, we hope, future practice in Bayesian cognitive science.

The increasing use of cluster randomised trials in low-resource settings raises unique ethical issues. The Ottawa Statement on the Ethical Design and Conduct of Cluster Randomised Trials is the first international ethical guidance document specific to cluster trials, but it is unknown if it adequately addresses issues in low-resource settings. In this paper, we seek to identify any gaps in the Ottawa Statement relevant to cluster trials conducted in low-resource settings. Our method is to analyse a prototypical cluster trial conducted (...) in a low-resource setting with the Ottawa Statement; to identify ethical issues in the design or conduct of the trial not captured adequately and to make recommendations for issues needing attention in forthcoming revisions to the Ottawa Statement. Our analysis identified six ethical aspects of cluster randomised trials in low-resource settings that require further guidance. The forthcoming revision of the Ottawa Statement should provide additional guidance on these issues: streamlining research ethics committee review for collaborating investigators who are affiliated with other institutions; the classification of lay health workers who deliver study interventions as health providers or research participants; the dilemma experienced by investigators when national standards seem to prohibit waivers of consent; the timing of gatekeeper engagement, particularly when researchers face funding constraints; providing ancillary care in health services or implementation trials when a routine care control arm is known to fall below national standards and defining vulnerable participants needing protection in low-resource settings.

Fractal structure is a ubiquitous property found in nature and biology, and has been observed in processes at different levels of organization, including rhythmic behavior and musical structure. A temporal process is characterized as fractal when serial long-term correlations and statistical self-similarity (scaling) are present. Previous studies of sensorimotor synchronization using isochronous (non-fractal) stimuli show that participants' errors exhibit persistent structure (positive long-term correlations), while their inter-tap intervals (ITIs) exhibit anti-persistent structure (negative long-term correlations). Auditory-motor synchronization has not been investigated (...) with anti-persistent stimuli. In the current study, we systematically investigated whether the fractal structure of auditory rhythms was reflected in the responses of participants who were asked to coordinate their taps with each event. We asked musicians and non-musicians to tap with 12 different rhythms that ranged from anti-persistent to persistent. The scaling exponents of the ITIs were strongly correlated with the scaling exponents of the stimuli, showing that the long-term structure of the participants' taps scaled with the long-term structure of the stimuli. Surprisingly, the performance of the musicians was not significantly better than that of the non-musicians. Our results imply that humans are able to readily adapt (rather than simply react) to the overall statistical structure of temporally fluctuating stimuli, regardless of musical skill. (shrink)

Distinctive aspects of a culture are often reflected in the meaning and usage of words in the language spoken by bearers of that culture. Keywords such as душа (soul) in Russian, hati (heart) in Indonesian and Malay, and gezellig (convivial/cosy/fun) in Dutch are held to be especially culturally revealing, and scholars have identified a number of such keywords using careful linguistic analyses (Peeters, 2020b; Wierzbicka, 1990). Because keywords are expected to have different statistical properties than related words in other languages, (...) we argue that a quantitative comparison of word usage across languages can help to identify cultural keywords. To support this claim, we describe a computational method that compares word frequencies across languages, and apply it to both linguistic corpora and word association data. The method identifies culturally specific words that range from “obvious” examples, such as Amsterdam in Dutch, to non‐obvious yet independently proposed examples, such as hati (heart) in Indonesian. We show in addition that linguistic corpora and word association data provide converging evidence about culturally specific words. Our results therefore show how computational analyses and behavioral experiments can supplement the methods previously used by linguists to identify culturally salient words across languages.

An advertising firm''s ethical culture (as defined by the firm''s managerial and peer ethical behaviors) may affect the employees'' comfort levels and ethical behaviors. In this research, scenarios were used to describe advertising firms with various ethical cultures. Respondents'' perceived comfort levels in working for the firms described in the scenarios and the respondents'' behavioral intentions when faced with various advertising situations were assessed. Results of the study indicate that peer ethical behavior exerts a strong influence on the comfort or (...) discomfort level and the ethical behavioral intentions of potential advertising employees. Further, the strong influence exerted by peers seems to transcend the ethical behavior of the manager and carry over to the attitude toward the entire corporate advertising environment. This study provides insights for firms and researchers interested in assessing the impact of an advertising firm''s ethical culture on potential employees. (shrink)

The gelsolin gene family encodes a number of higher eukaryotic actin-binding proteins that are thought to function in the cytoplasm by severing, capping, nucleating or bundling actin filaments. Recent evidence, however, suggests that several members of the gelsolin family may have adopted unexpected nuclear functions including a role in regulating transcription. In particular, flightless I, supervillin and gelsolin itself have roles as coactivators for nuclear receptors, despite the fact that their divergence appears to predate the evolutionary appearance of nuclear receptors. (...) Flightless I has been shown to bind both actin and the actin-related BAF53a protein, which are subunits of SWI/SNF-like chromatin remodelling complexes. The primary sequences of some actin-related proteins such as BAF53a exhibit conservation of residues that, in actin itself, are known to interact with gelsolin-related proteins. In summary, there is a growing body of evidence supporting a biological role in the nucleus for actin, Arps and actin-binding proteins and, in particular, the gelsolin family of actin-binding proteins.

BackgroundIt is commonly reported by editors that it has become harder to recruit reviewers for peer review and that this is because individuals are being asked to review too often and are experiencing reviewer fatigue. However, evidence supporting these arguments is largely anecdotal.Main bodyWe examine responses of individuals to review invitations for six journals in ecology and evolution. The proportion of invitations that lead to a submitted review has been decreasing steadily over 13 years (2003–2015) for four of the six (...) journals examined, with a cumulative effect that has been quite substantial (average decline from 56% of review invitations generating a review in 2003 to just 37% in 2015). The likelihood that an invitee agrees to review declines significantly with the number of invitations they receive in a year. However, the average number of invitations being sent to prospective reviewers and the proportion of individuals being invited more than once per year has not changed much over these 13 years, despite substantial increases in the total number of review invitations being sent by these journals—the reviewer base has expanded concomitant with this growth in review requests.ConclusionsThe proportion of review invitations that lead to a review being submitted has been declining steadily for four of the six journals examined here, but reviewer fatigue is not likely the primary explanation for this decline.

Beginning with Ronald Hepburn’s path-breaking essay, “Contemporary Aesthetics and the Neglect of Natural Beauty,” which helped establish the modern discipline of environmental aesthetics, philosophers have provided sketches of what, after Hegel, might be called “philosophical histories of the aesthetics of nature.” These histories are remarkably similar and can easily be blended together to create a “received history” of the discipline. This history has subtly influenced work in the field. Unfortunately, it is not completely accurate and, as a result, has had (...) a misleading effect. A more accurate and expanded alternative history calls into question the received history’s view both on the origins of the field in arts-based aesthetic theories and on the nature and value of the aesthetic categories, “the picturesque” and “the sublime.” These categories were not borrowed from philosophy of art and inappropriately applied to nature, but instead were developed to appraise landscapes, which unlike natural objects could only rarely be judged beautiful since they are almost never symmetrical or ordered.

Reduction has long been a favourite method of analysis in all areas of philosophy, but in recent years there has been a reaction against it. The contributors to this volume examine the motivations for such anti-reductionist views and assess their coherence and success in a number of fields.

One common objection to ethical vegetarianism—that is, vegetarianism for ethical reasons—concerns the morality of the predator-prey relationship. If it is morally acceptable for wolves to kill sheep for food, why is it wrong for human beings to eat meat? The objection raised here is sometimes called the “predation argument.” In this article, I critically examine three versions of the argument.

"In Getting Even, Charles Barton contends that revenge can be a form of justice that is constructive and healing for our society. Our current judiciary system, he explains, denies both victims and the accused an active role in the legal proceedings and resolution of their cases, reducing them to bystanders in what is essentially their own conflict. Barton does not argue for an individual's right to take the law into his own hands, but does show that the courts should (...) recognize the revenge motive as legitimate and rational within the rules of justice."--pub. desc.

Buddhism famously denies the existence of the self. This is usually understood to mean that Buddhism denies the existence of a substantial self existing over and above the flow of conscious experience. But what of the purely experiential self accepted by the phenomenological tradition? Does Buddhism deny the reflexive or first-personal character of conscious experience? In this paper, I argue that even the notion of an experiential self is ultimately incompatible with Buddhist teaching—in fact, deeply incompatible. According to Buddhism, I (...) am an objectively existing person (though not irreducibly real). However, when I conceive of myself as myself, I conceive of myself as having a subjective mode of existence. What Buddhism denies, then, is not that I exist, but that I exist in the subjective or first-person manner in which I conceive of myself as existing. The problem I take up in this paper is to understand how Buddhism can simultaneously affirm the reflexivity of conscious experience and yet deny that the experiential self is a self. (shrink)
