A variety of theoretical frameworks predict the resemblance of behaviors between two people engaged in communication, in the form of coordination, mimicry, or alignment. However, little is known about the time course of the behavior matching, even though there is evidence that dyads synchronize oscillatory motions (e.g., postural sway). This study examined the temporal structure of nonoscillatory actions—language, facial, and gestural behaviors—produced during a route communication task. The focus was the temporal relationship between matching behaviors in the interlocutors (e.g., facial (...) behavior in one interlocutor vs. the same facial behavior in the other interlocutor). Cross-recurrence analysis revealed that within each category tested (language, facial, gestural), interlocutors synchronized matching behaviors, at temporal lags short enough to provide imitation of one interlocutor by the other, from one conversational turn to the next. Both social and cognitive variables predicted the degree of temporal organization. These findings suggest that the temporal structure of matching behaviors provides low-level and low-cost resources for human interaction. (shrink)

Whether computational algorithms such as latent semantic analysis (LSA) can both extract meaning from language and advance theories of human cognition has become a topic of debate in cognitive science, whereby accounts of symbolic cognition and embodied cognition are often contrasted. Albeit for different reasons, in both accounts the importance of statistical regularities in linguistic surface structure tends to be underestimated. The current article gives an overview of the symbolic and embodied cognition accounts and shows how meaning induction attributed to (...) a specific statistical process or to activation of embodied representations should be attributed to language itself. Specifically, the performance of LSA can be attributed to the linguistic surface structure, more than special characteristics of the algorithm, and embodiment findings attributed to perceptual simulations can be explained by distributional linguistic information.

Recent theories of cognition have argued that embodied experience is important for conceptual processing. Embodiment can be contrasted with linguistic factors such as the typical order in which words appear in language. Here, we report four experiments that investigated the conditions under which embodiment and linguistic factors determine performance. Participants made speeded judgments about whether pairs of words or pictures were semantically related or had an iconic relationship. The embodiment factor was operationalized as the degree to which stimulus pairs were (...) presented in the spatial configurations in which they usually occur (i.e., an iconic configuration, e.g., attic presented above basement). The linguistic factor was operationalized as the frequency of the stimulus pairs in language. The embodiment factor predicted error rates and response time better for pictures, whereas the linguistic factor predicted error rates and response time better for words. These findings were modified by task, with the embodiment factor being strongest in iconicity judgments for pictures and the linguistic factor being strongest in semantic judgments for words. Both factors predicted error rates and response time for both semantic and iconicity judgments. These findings support the view that conceptual processing is both linguistic and embodied, with a bias for the embodiment or the linguistic factor depending on the nature of the task and the stimuli.

In an evolutionary perspective Louwerse elaborates the Symbol Interdependency Hypothesis (Louwerse, 2011), arguing that language has evolved such that it maps onto the perceptual system, allowing to bootstrap meaning also when grounding is limited. The author concludes that in principle the processing of abstract and concrete words is the same and that in both cases language users tend to rely anyway on indexical relationships that words entertain with other words.

Population counts and longitude and latitude coordinates were estimated for the 50 largest cities in the United States by computational linguistic techniques and by human participants. The mathematical technique Latent Semantic Analysis applied to newspaper texts produced similarity ratings between the 50 cities that allowed for a multidimensional scaling (MDS) of these cities. MDS coordinates correlated with the actual longitude and latitude of these cities, showing that cities that are located together share similar semantic contexts. This finding was replicated using (...) a first‐order co‐occurrence algorithm. The computational estimates of geographical location as well as population were akin to human estimates. These findings show that language encodes geographical information that language users in turn may use in their understanding of language and the world. (shrink)

Two eye-tracking experiments investigated how and when pointing gestures and location descriptions affect target identification. The experiments investigated the effect of gestures and referring expressions on the time course of fixations to the target, using videos of human gestures and human voice, and animated gestures and synthesized speech. Ambiguous, yet informative pointing gestures elicited attention and facilitated target identification, akin to verbal location descriptions. Moreover, target identification was superior when both pointing gestures and verbal location descriptions were used. These findings (...) suggest that gesture not only operates as a context to verbal descriptions, or that verbal descriptions operate as a context to gesture, but that they complement one another in reference resolution.

Spatial mental representations can be derived from linguistic and non‐linguistic sources of information. This study tested whether these representations could be formed from statistical linguistic frequencies of city names, and to what extent participants differed in their performance when they estimated spatial locations from language or maps. In a computational linguistic study, we demonstrated that co‐occurrences of cities in Tolkien’s Lord of the Rings trilogy and The Hobbit predicted the authentic longitude and latitude of those cities in Middle Earth. In (...) a human study, we showed that human spatial estimates of the location of cities were very similar regardless of whether participants read Tolkien’s texts or memorized a map of Middle Earth. However, text‐based location estimates obtained from statistical linguistic frequencies better predicted the human text‐based estimates than the human map‐based estimates. These findings suggest that language encodes spatial structure of cities, and that human cognitive map representations can come from implicit statistical linguistic patterns, from explicit non‐linguistic perceptual information, or from both.

Computational techniques comparing co-occurrences of city names in texts allow the relative longitudes and latitudes of cities to be estimated algorithmically. However, these techniques have not been applied to estimate the provenance of artifacts with unknown origins. Here, we estimate the geographic origin of artifacts from the Indus Valley Civilization, applying methods commonly used in cognitive science to the Indus script. We show that these methods can accurately predict the relative locations of archeological sites on the basis of artifacts of (...) known provenance, and we further apply these techniques to determine the most probable excavation sites of four sealings of unknown provenance. These findings suggest that inscription statistics reflect historical interactions among locations in the Indus Valley region, and they illustrate how computational methods can help localize inscribed archeological artifacts of unknown origin. The success of this method offers opportunities for the cognitive sciences in general and for computational anthropology specifically. (shrink)

What role do linguistic cues on a surface and contextual level have in identifying the intention behind an utterance? Drawing on the wealth of studies and corpora from the computational task of dialog act classification, we studied this question from a cognitive science perspective. We first reviewed the role of linguistic cues in dialog act classification studies that evaluated model performance on three of the most commonly used English dialog act corpora. Findings show that frequency‐based, machine learning, and deep learning (...) methods all yield similar performance. Classification accuracies, moreover, generally do not explain which specific cues yield high performance. Using a cognitive science approach, in two analyses, we systematically investigated the role of cues in the surface structure of the utterance and cues of the surrounding context individually and combined. By comparing the explained variance, rather than the prediction accuracy of these cues in a logistic regression model, we found that (1) while surface and contextual linguistic cues can complement each other, surface linguistic cues form the backbone in human dialog act identification, (2) with word frequency statistics being particularly important for the dialog act, and (3) the similar trends across corpora, despite differences in the type of dialog, corpus setup, and dialog act tagset. The importance of surface linguistic cues in dialog act classification sheds light on how both computers and humans take advantage of these cues in speech act recognition. (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)

The Overview Effect is the commonly reported experience of astronauts viewing planet Earth from space, and the subsequent reflection on, and processing of this experience. The Overview Effect is associated with feelings of awe, self-transcendence, and a change of perspective and identity that manifest themselves in taking steps towards protecting the fragile ecosystem. In the current study, we investigated whether the Overview Effect can be obtained in school children when simulated using virtual reality and whether the effect has a positive (...) impact on learning gains. Using questionnaires and attention data in an existing simulation environment used in the school system, we showed that the virtual reality simulation elicits an Overview Effect experience. Moreover, the experience yields learning gains in the domain of astrophysics. These findings are in line with past evidence regarding the positive impact of awe on learning and can be used to support further investigations of the relation between the Overview Effect and behavioral changes, specifically for educational purposes.

In lieu of an abstract, here is a brief excerpt of the content:149. RELATIVE IDEAS REJECTED Hume's claim that ideas copy impressions seems to provide prima facie evidence for the interpretation that he also believed that all thought is restricted to images. Clearly such a view would be fatal to Hume's epistemological framework for at least two reasons. The first reason is quite simply that images are not a necessary element for thought, since we rarely think in images or pictures. (...) The second reason is that the imagistic interpretation prevents the possibility of universal a priori knowledge; since images only represent particulars they can never permit the inference from knowledge of particular instances to knowledge of universal cases. Yolton's paper, "Hume's Ideas", is a valiant effort to save Hume from the crippling imagistic interpretation. Although Yolton presents a reading of the Treatise that might avoid this interpretation, he fails to provide a sufficiently detailed account of any one counter-example to the imagistic view of Hume. However, such a counter-example has been worked out in Flage's 2 recent paper "Hume's Relative Ideas". Although the search for non-picturable ideas in Hume's system, and subsequent destruction of the imagistic interpretation is an admirable path for investigation, I intend to show that Flage's attempt to produce a Humean theory of non3 picturable "relative" ideas is entirely misguided. I shall argue that Flage has produced a theory without application in Hume's framework, a theory actually based on a distinction between relative ideas and relations of ideas, that Hume never intends. Flage argues that Hume has a theory of relative ideas, and that the application of this theory can produce intelligible concepts of essentially imperceptible 150. objects. A relative idea is obtained by an inference, of sorts, from the relations of ideas obtained from impressions; or in Flage' s words, a relative idea "singles out an unperceived entity on the basis of its relations to a perceived entity, i.e. a positive [picturable] idea" (HS 56). Flage admits that "Hume often regarded epistemic claims based upon relative ideas with at least a modicum of scepticism" (HS 55). He also realizes that no such theory of relative ideas can be used to justify ontological claims of the unperceivable objects (HS 63), but that "the doctrine of relative ideas at least accounts for the intelligibility of various concepts" (HS 59). Flage applies the theory of relative ideas to three concepts that Hume discusses in an effort to demonstrate how this theory can make these concepts intelligible. The three concepts are substratum, the missing shade of blue, and the idea of a thousandth part of a grain of sand; however, Flage fails to realize that Hume successfully argues against the intelligibility of these concepts. I shall present the arguments that Hume gives to show that Flage' s theory of relative ideas does not apply in the cases he argues for. Hopefully this will show that Flage has created a theory that lacks application; however, this is not Flage' s only failing. "Relative" ideas are obtained from relations of ideas (HS 56), and by this description Flage has implicitly distinguished between Hume's use of "relative" and the philosophical "relations of ideas!', a distinction that Hume never intends. In the latter part of this paper I shall show that Hume uses "relative" to refer to the relations of ideas, and that Flage has simply located and produced a theory on the basis of a distinction that has no real difference. In the discussion of substance, Flage correctly points out that Hume distinguishes three definitions of substance in the fourth part of book I of the Treatise (HS 63-4). 151. Flage also correctly points out that at least two of these definitions are unintelligible (HS 64). The definition of substance, as an autonomous object that is distinct from dependent qualities, fails to properly 4 distinguish substance from qualities (T 233), and substance defined as the "subject of inhesion" fails because there is no empirical evidence to justify the claim that qualities inhere in a substance J(T 234). However, Flage incorrectly argues that Hume asserts that the idea of substance as "the entity that is simple and identical through time... (shrink)

Music comprises a diverse category of cognitive phenomena that likely represent both the effects of psychological adaptations that are specific to music (e.g., rhythmic entrainment) and the effects of adaptations for non-musical functions (e.g., auditory scene analysis). How did music evolve? Here, we show that prevailing views on the evolution of music – that music is a byproduct of other evolved faculties, evolved for social bonding, or evolved to signal mate quality – are incomplete or wrong. We argue instead that (...) music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. Specifically, we propose that (1) the production and reception of coordinated, entrained rhythmic displays is a co-evolved system for credibly signaling coalition strength, size, and coordination ability; and (2) the production and reception of infant-directed song is a co-evolved system for credibly signaling parental attention to secondarily altricial infants. These proposals, supported by interdisciplinary evidence, suggest that basic features of music, such as melody and rhythm, result from adaptations in the proper domain of human music. The adaptations provide a foundation for the cultural evolution of music in its actual domain, yielding the diversity of musical forms and musical behaviors found worldwide. (shrink)

We discuss approaches to the study of the evolution of music (sect. R1); challenges to each of the two theories of the origins of music presented in the companion target articles (sect. R2); future directions for testing them (sect. R3); and priorities for better understanding the nature of music (sect. R4).

Metastatic spread of tumor cells is one of the most common causes of death in cancer patients. Therefore, elucidation of the molecular mechanisms that underlie the formation of metastatic colonies has been one of the major objectives of cancer research during the last two decades. In this review we will mainly discuss the mechanisms that cause a malignant cell to grow at a given site rather than at other possible sites, taking into account experimental and clinical evidence published on the (...) subject. As a whole this evidence tends to confirm the hypothesis that organ‐specific colonization by malignant cells often follows very specific and close interactions between the cancer cell and the target organ, either in terms of specific cellular adhesion or growth promotion. In this paper we would like to underscore the fact that cellular adhesion, either specific or unspecific, is a necessary but, by itself, insufficient condition for the development of metastases. It is the ability of the tumor cells to grow at the site where they arrested that ultimately determines whether a metastatic colony develops or fails to develop at that site. (shrink)

The book "Philosophical Foundations of Neuroscience" is an engaging criticism of cognitive neuroscience from the perspective of a Wittgensteinian philosophy of ordinary language. The authors' main claim is that assertions like "the brain sees" and "the left hemisphere thinks" are integral to cognitive neuroscience but that they are meaningless because they commit the mereological fallacy—ascribing to parts of humans, properties that make sense to predicate only of whole humans. The authors claim that this fallacy is at the heart of Cartesian (...) dualism, implying that current cognitive neuroscientists are Cartesian dualists. Against this claim, we argue that the fallacy cannot be committed within Cartesian dualism either, for this doctrine does not allow for an intelligible way of asserting that a soul is part of a human being. Also, the authors' Aristotelian essentialistic outlook is at odds with their Wittgensteinian stance, and we were unconvinced by their case against explanatory reductionism. Finally, although their Wittgensteinian stance is congenial with radical behaviorism, their separation between philosophy and science seems less so because it is based on a view of philosophy as a priori. The authors' emphasis on the a priori, however, does not necessarily commit them to rationalism if it is restricted to conceptual or analytical truths. (shrink)

Previous studies have shown that object properties are processed faster when they follow properties from the same perceptual modality than properties from different modalities. These findings suggest that language activates sensorimotor processes, which, according to those studies, can only be explained by a modal account of cognition. The current paper shows how a statistical linguistic approach of word co-occurrences can also reliably predict the category of perceptual modality a word belongs to (auditory, olfactory–gustatory, visual–haptic), even though the statistical linguistic approach (...) is less precise than the modal approach (auditory, gustatory, haptic, olfactory, visual). Moreover, the statistical linguistic approach is compared with the modal embodied approach in an experiment in which participants verify properties that share or shift modalities. Response times suggest that fast responses can best be explained by the linguistic account, whereas slower responses can best be explained by the embodied account. These results provide further evidence for the theory that conceptual processing is both linguistic and embodied, whereby less precise linguistic processes precede precise simulation processes.

Max Picard (1888-1965) was a Swiss-German writer, who converted to Catholicism from Judaism. A doctor and psychologist, Picard worked in Berlin but retired in the 1920s to Switzerland. He is often regarded as a "wisdom thinker," and his rich and penetrating writings continue to speak to us in the twenty-first century. The Flight from God is an incisive, profound description of many of the problems facing modern culture, and its analysis resonates with us more today than when first published in (...) 1934. Picard illustrates that modern culture is essentially in Flight, and so the individual is under pressure to make a choice; in earlier generations only an individual could be in flight because the culture itself was not in flight but in Faith. The flight does not require courage or guilt; yet it is to be found in, and is often destructive of, many facets of life including human relationships, art, economics, science, entertainment, even religion. Because of this it leaves many in anguish, from which we seek alternative avenues of structure and meaning. Yet, in every person there is a residue that will not yield itself to the flight, and this is bound up with love, which reminds us of God. Picard shows how God is always somehow present in the flight--just when we think we are arriving from the flight, we find that God is already there. Picard's identification and discussion of the roots of the distresses of modern culture, and its attempts to grapple with the spiritual dimension of human experience, along with tensions created by freedom and individuality, are clearly still of the greatest relevance for us today.

Writing from a scientifically and philosophically informed perspective, the authors provide a critical overview of the conceptual difficulties encountered in many current neuroscientific and psychological theories.

This paper explores the influence of social categories on the perceived trade-off between a relatively bad but equal distribution of resources between two parties and a profit maximizing yet unequal one. Studies 1 and 2 showed that people prefer to maximize profits when interacting within their social category, but chose not to maximize individual and joint profits when interacting across social categories. Study 3 demonstrated that outside observers, who were not members of the focal social categories, also were less likely (...) to maximize profits when resources were distributed across social category lines. Study 4 showed that the transaction utility of maximizing profits required greater compensation when resources were distributed across, in contrast to within social categories. We discuss the ethical implications of these decision making biases in the context of organizations. (shrink)

This Introduction to a Journal of Consciousness Studies Special Issue on Monist Alternatives to Physicalism summarises some of the basic problems of Physicalism and common fallacies in arguments for its defence that are found in the philosophical and scientific literature. It then introduces six monist alternatives: 1) a form of emergent panpsychism developed by William Seager; 2) a novel introduction to the process philosophy of A.N. Whitehead by Anderson Weekes; 3) a review of current developments in Russellian Monism by Torin (...) Alter and Yujin Nagasawa; 4) an analysis of dual-aspect monism and its relation to quantum mechanics originally proposed developed by Pauli and Jung and given a modern interpretation by Harald Atmanspacher; 5) a form of processing monism that might help to resolve ontological differences in Indian philosophy and psychology between dualist Samkya Yoga and nondualist Advaita Vedanta by K. Ramakrisna Rao; and 6) an account of Reflexive Monism, which, viewed as a global system, can incorporate many of the seemingly opposed “isms” that currently populate Consciousness Studies by Max Velmans. Whatever the fundamental nature of Nature might be, it must have the power to give rise to its observable manifestations. Consequently, all the papers in this issue are concerned to give a “natural” account of the relationships among consciousness, mind, and the material world that is entirely consistent with the findings of science, and they all accept that for a unified understanding, mind, consciousness and the material world must have a common base. The aim of the Special Issue is to contribute to a deeper understanding of that base, and to stimulate novel thinking about its nature. (shrink)
