Human neural and behavioral activities have been reported to exhibit fractal dynamics known as 1/f noise, which is more aptly named 1/f scaling. Some argue that 1/f scaling is a general and pervasive property of the dynamical substrate from which cognitive functions are formed. Others argue that it is an idiosyncratic property of domain‐specific processes. An experiment was conducted to investigate whether 1/f scaling pervades the intrinsic fluctuations of a spoken word. Ten participants each repeated the word bucket over 1,000 (...) times, and fluctuations in acoustic measurements across repetitions generally followed the 1/f scaling relation, including numerous parallel yet distinct series of 1/f fluctuations. On the basis of work showing that 1/f scaling is a universal earmark of metastability, it is proposed that the observed pervasiveness of 1/f fluctuations in speech reflects the fact that cognitive functions are formed as metastable patterns of activity in brain, body, and environment.

The literature on coordination within and between individuals is reviewed, with an emphasis on the inherent transience of coordination patterns in behavioral activity. This transience is integral to understanding cognitive activity as flexible patterns of coordination in brain, body, and environment. Kello reviews the articles in this special issue as contributions to understanding the role of context in shaping or interpreting coordination patterns in human behavior.

The forms of words as they appear in text and speech are central to theories and models of lexical processing. Nonetheless, current methods for simulating their learning and representation fail to approach the scale and heterogeneity of real wordform lexicons. A connectionist architecture termed thesequence encoderis used to learn nearly 75,000 wordform representations through exposure to strings of stress‐marked phonemes or letters. First, the mechanisms and efficacy of the sequence encoder are demonstrated and shown to overcome problems with traditional slot‐based (...) codes. Then, two large‐scale simulations are reported that learned to represent lexicons of either phonological or orthographic wordforms. In doing so, the models learned the statistics of their lexicons as shown by better processing of well‐formed pseudowords as opposed to ill‐formed (scrambled) pseudowords, and by accounting for variance in well‐formedness ratings. It is discussed how the sequence encoder may be integrated into broader models of lexical processing. (shrink)

We discuss two problems for a general scientific understanding of language, sequences and synergies: how language is an intricately sequenced behavior and how language is manifested as a multidimensionally structured behavior. Though both are central in our understanding, we observe that the former tends to be studied more than the latter. We consider very general conditions that hold in human brain evolution and its computational implications, and identify multimodal and multiscale organization as two key characteristics of emerging cognitive function in (...) our species. This suggests that human brains, and cognitive function specifically, became more adept at integrating diverse information sources and operating at multiple levels for linguistic performance. We argue that framing language evolution, learning, and use in terms of synergies suggests new research questions, and it may be a fruitful direction for new developments in theory and modeling of language as an integrated system.

Sibley, Kello, Plaut, and Elman (2008) proposed the sequence encoder as a model that learns fixed‐width distributed representations of variable‐length sequences. In doing so, the sequence encoder overcomes problems that have restricted models of word reading and recognition to processing only monosyllabic words. Bowers and Davis (2009) recently claimed that the sequence encoder does not actually overcome the relevant problems, and hence it is not a useful component of large‐scale word‐reading models. In this reply, it is noted that the (...) sequence encoder has facilitated the creation of large‐scale word‐reading models. The reasons for this success are explained and stand as counterarguments to claims made by Bowers and Davis. (shrink)

Recent studies of naturalistic face‐to‐face communication have demonstrated coordination patterns such as the temporal matching of verbal and non‐verbal behavior, which provides evidence for the proposal that verbal and non‐verbal communicative control derives from one system. In this study, we argue that the observed relationship between verbal and non‐verbal behaviors depends on the level of analysis. In a reanalysis of a corpus of naturalistic multimodal communication (Louwerse, Dale, Bard, & Jeuniaux, ), we focus on measuring the temporal patterns of specific (...) communicative behaviors in terms of their burstiness. We examined burstiness estimates across different roles of the speaker and different communicative modalities. We observed more burstiness for verbal versus non‐verbal channels, and for more versus less informative language subchannels. Using this new method for analyzing temporal patterns in communicative behaviors, we show that there is a complex relationship between verbal and non‐verbal channels. We propose a “temporal heterogeneity” hypothesis to explain how the language system adapts to the demands of dialog. (shrink)

Recent studies of semantic memory have investigated two theories of optimal search adopted from the animal foraging literature: Lévy flights and marginal value theorem. Each theory makes different simplifying assumptions and addresses different findings in search behaviors. In this study, an experiment is conducted to test whether clustering in semantic memory may play a role in evidence for both theories. Labeled magnets and a whiteboard were used to elicit spatial representations of semantic knowledge about animals. Category recall sequences from a (...) separate experiment were used to trace search paths over the spatial representations of animal knowledge. Results showed that spatial distances between animal names arranged on the whiteboard were correlated with inter-response intervals during category recall, and distributions of both dependent measures approximated inverse power laws associated with Lévy flights. In addition, IRIs were relatively shorter when paths first entered animal clusters, and longer when they exited clusters, which is consistent with marginal value theorem. In conclusion, area-restricted searches over clustered semantic spaces may account for two different patterns of results interpreted as supporting two different theories of optimal memory foraging.

We describe an approach that enables a more complete evaluation of the validity of emotional intelligence measures. We argue that a source of evidence for validity is often overlooked by researchers and test developers, namely, evidence based on response processes. This evidence can be obtained through a definition of the ability, a description of the mental processes that operate when a person uses the ability, the development of a theory of response behaviour that links variation in the construct with variation (...) on the responses to the items of a measure, and a test of the theory of response behaviour through one or more strategies that we describe.

We begin by discussing some logical constraints on the psychological approach to personal identity. We consider a problem for the psychological approach that arises in fission cases. The problem engenders the need for a non-branching clause in a psychological account of the co-personality relation. We look at some difficulties in formulating such a clause. We end by rejecting a recently proposed formulation of non-branching. Our criticism of the formulation raises some interesting questions about the individuation of person stages.

Derek Parfit has offered numerous arguments in an attempt to establish that identity is not what matters. Jens Johannson has recently argued that Parfit's various arguments for the claim that identity is not what matters fail to establish what Parfit takes such arguments to establish. Johannson contends that this is due in part to the invalidity of one of Parfit's key arguments, and the fact that Parfit ignores a position that is compatible with the conclusions of his successful arguments and (...) the claim that identity is in fact what matters, namely, that I survive fission as either one of the fission products or the other, but it is indeterminate which one I survive as. I aim to establish here that both of Johannson's assertions are problematic. As a corollary of this task, I hope to shed some light on the relationship between indeterminacy and fission-based arguments for the claim that identity is not what matters. (shrink)

This chapter focuses on synaesthesia research in the 21st century. It begins by giving counts of publications and these are further broken down by type, focus, and measures used. Then, there is a review of major questions being addressed by current research in the area of synaesthesia. The amount of research being done in this area is growing rapidly, and is incorporating a number of different research approaches to address a wide variety of questions.

This article explores four topics raised by Eyal Zamir and Barak Medina's treatment of constrained deontology. First, it examines whether mathematical threshold functions are the proper way to think about limits on deontology, given the discontinuities of our moral judgments and the desired phenomenology of rule-following. Second, it asks whether constrained deontology is appropriate for public as well as private decision-making, taking issue with the book's conclusion that deontological options are inapplicable to public decision-making, whereas deontological constraints are applicable. Third, (...) it examines the issue of the relationship between deontology and efficiency, asking whether deontological constraints should yield in situations where everyone would expect to benefit from their suspension, either ex ante or ex post . Finally, the article concludes that constrained deontology is susceptible to political abuse because of the many degrees of freedom involved in identifying constrained actions and the point at which those constraints yield to consequentialist benefits.

_ Source: _Volume 5, Issue 1, pp 55 - 60 Peter Murphy has argued that effective skeptical scenarios all have the following feature: the subject involved in the scenario does not know that some ordinary proposition is true, even if the proposition is true in the scenario. So the standard “false belief” conception of skeptical scenarios is wrong, since the belief of the targeted proposition need not be mistaken in the scenario. Murphy then argues that this observation engenders a problem (...) for skeptical arguments: they require the KK principle. We respond to this criticism on behalf of the skeptic in our paper.

Based on the assumption that confrontation with one’s physical reflection can be aversive, we explored the appeal of possible “escape routes” when incidentally exposed to one’s mirror image. Compared to their no-exposure peers, individuals who felt less chronically “trapped” in their bodies showed increased interest in flow experiences and decreased interest in experiences involving low-level thinking or a subjective sense of meaning when exposed to their reflection. Mirror exposure also increased overall interest in “pure consciousness events,” wherein the transcendence of (...) space and time figures centrally. The aversive effects of even implicit confrontation with one’s reflection therefore seem more diverse than anticipated based on existing frameworks such as Objective Self-Awareness theory, so additional theoretical development seems warranted.

Buprenorphine is a form of opioid agonist treatment that has been demonstrated to be an effective medication for opioid addiction. It is available in different formulations and marketed under various trade names, including commonly as a buprenorphine/naloxone combination. This paper provides an overview of existing literature on the supply of buprenorphine treatment, the ability of people to access treatment with buprenorphine, and the quality of treatment received. We argue that better data for each of these aspects of treatment could inform (...) policy to expand effective treatment with buprenorphine, and we suggest steps to obtain and act on such data.

Those who endorse a knowledge-first program in epistemology claim that rather than attempting to understand knowledge in terms of more fundamental notions or relations such as belief and justification, we should instead understand knowledge as being in some sense prior to such concepts and/or relations. If we suppose that this is the correct approach to theorizing about knowledge, we are left with a residual question about the nature of those concepts or relations, such as justification, that were thought to be (...) first but are now second. Jonathan Jenkins Ichikawa has recently proposed that we understand justification in terms of potential knowledge. Ichikawa combines his view of knowledge and justification with what initially seems to be a natural complement, epistemological disjunctivism. While Ichikawa focuses on hallucination, I shift the focus to illusion. I argue that the combination of justification as potential knowledge and epistemological disjunctivism entails that perceptual beliefs that arise from illusions are not justified. (shrink)

To test whether emotional empathy is linked to altered perceptions of self in relation to other and/or context, participants read one of two tragic news stories and then completed a self-report empathy measure, as well as an abridged version of Hood’s Mysticism scale either before or after the article. Exposure to a needy other in the story tended to result in greater self-reported mystical experience. Men with a history of mystical experience reported more empathy, but the latter was disconnected from (...) on-line reports of mystical experience. Women’s history of mystical experience did not predict empathic responding overall, but their reported empathy was linked to on-line experiences of oneness, absorption into something larger, and space-time distortion with imputed religious significance. Directions for future research, including the possible facilitative role of oxytocin, are discussed. (shrink)

Both in the pre-war and the post-war period right-wing extremism was not very strong in Britain. Historians, political scientist and politicians have suggested a whole range of elements to explain this failure. In the light of this limited success the victory of the British National Party in an election of the Millwall district in the London Bourough of Tower Hamlets was indeed a surprise. lt raised the question whether this was the beginning of something similar to what happened earlier in (...) France, Germany, Belgium and the Netherlands. The very specific characteristics of the London East End and ofthe Millwall district in particular make the BNP victory however quite exceptional, and do not enable a generalization of the phenomenon. This is supported by the electoral results for the London Borough and District Council of May 5 1994. Yet one can still argue that the specific danger of the BNP is not its electoral potential, but the impact of its local activities on the relations between the ethnic groups in the neighbourhoods where it is present.

There is an apparent problem stemming from the factivity of knowledge that seems to afflict both contextualism and subject-sensitive invariantism . 1 In this article, we will first explain how the problem arises for each theory, and then we will propose a uniform resolution.1. The factivity problem for contextualismLet K t stands for X knows _ at t. Let h stand for S has hands. According to contextualism, ‘K t’ is true as uttered in some ordinary conversational contexts. Let O (...) be such a context. So we have ‘K t’ is true in O.Consider a demanding conversational context D . Let S* be a participant in D. We have ‘K t’ is not true in D.In prose: ‘S* knows at t that S has hands’ is not true in D. 2 , 3 Let us suppose that S* has a favourable epistemic status with respect to , as follows: ‘K t[S*,‘K t’ is true in O]’ is true in D. says that a certain sentence about S*'s epistemic status at t is true in D. S*'s epistemic status with respect to which proposition? A certain metalinguistic proposition concerning the truth in O of the sentence ‘K t’. That sentence in turn concerns S's epistemic status at t with respect to the proposition that S has hands. Got it? 4The factivity of ‘knows’ yields the following consequence : ‘K t’ is true in O → hThis metalinguistic factivity claim is licensed by the fact that any sentence of the …. (shrink)

We consider one of Eric Olson's chief arguments for animalism about personal identity: the view that we are each identical to a human animal. The argument was originally given in Olson's book The Human Animal . Olson's argument presupposes an epistemological premise which we examine in detail. We argue that the premise is implausible and that Olson's defense of animalism is therefore in trouble.

Non‐Interventionist Objective Divine Action (NIODA), introduced by Robert John Russell, is a model of divine action drawing upon insights from quantum mechanics. It presents an intriguing and significant challenge to classical conceptions of divine action with far‐reaching consequences. When applying NIODA to theistic evolution, however, significant questions emerge that require attention. We identify and assess two sets of concerns. The first relates to quantum physics, particularly whether and how quantum occurrences influence mutations and evolution. We argue that the current empirical (...) evidence is ambiguous in its support of the kinds of quantum action that Russell proposes, though emerging data from quantum biology look promising. The second set of concerns is metaphysical, especially concerning the problem of evil. NIODA gives Godextensive agency over evolution and genetics, which has adverse consequences for theodicy. We propose potential solutions to the problems highlighted in our article, both metaphysical and physical, to improve the viability of NIODA's application to theistic evolution. (shrink)

Kelly Becker has argued that in an externalist anti-luck epistemology, we must hold that knowledge requires the satisfaction of both a modalized tracking condition and a process reliability condition. We raise various problems for the examples that are supposed to establish this claim.
