Dialog is a joint action at different levels. At the highest level, the goal of interlocutors is to align their mental representations. This emerges from joint activity at lower levels, both concerned with linguistic decisions (e.g., choice of words) and nonlinguistic processes (e.g., alignment of posture or speech rate). Because of the high‐level goal, the interlocutors are particularly concerned with close coupling at these lower levels. As we illustrate with examples, this means that imitation and entrainment are particularly pronounced during (...) interactive communication. We then argue that the mechanisms underlying such processes involve covert imitation of interlocutors’ communicative behavior, leading to emulation of their expected behavior. In other words, communication provides a very good example of predictive emulation, in a way that leads to successful joint activity. (shrink)

This chapter examines the role of the situation model in referential processing and how it can link what appear to be incompatible results from studies of monologue and dialogue as well as studies of reading and visual-world eye tracking. It shows that data from experiments on pronoun resolution in reading indicate a two-step model, in which candidate antecedents for an anaphor are first identified on the basis of gender matching and number matching, then evaluated with respect to the overall situation (...) model. In similar visual-world studies, these stages are seemingly collapsed together, which can be explained in terms of differences in how the situation model is related to the text versus the visual display of potential referents. The chapter suggests that comparing these different types of studies can elucidate the processes of reference resolution. (shrink)

It has been suggested that iconic graphical signs evolve into symbolic graphical signs through repeated usage. This article reports a series of interactive graphical communication experiments using a ‘pictionary’ task to establish the conditions under which the evolution might occur. Experiment 1 rules out a simple repetition based account in favor of an account that requires feedback and interaction between communicators. Experiment 2 shows how the degree of interaction affects the evolution of signs according to a process of grounding. Experiment (...) 3 confirms the prediction that those not involved directly in the interaction have trouble interpreting the graphical signs produced in Experiment 1. On the basis of these results, this article argues that icons evolve into symbols as a consequence of the systematic shift in the locus of information from the sign to the users' memory of the sign's usage supported by an interactive grounding process.

This paper contrasts two influential theoretical accounts of language change and evolution – Iterated Learning and Social Coordination. The contrast is based on an experiment that compares drawings produced with Garrod et al’s ‘pictionary’ task with those produced in an Iterated Learning version of the same task. The main finding is that Iterated Learning does not lead to the systematic simplification and increased symbolicity of graphical signs produced in the standard interactive version of the task. A second finding is (...) that Iterated Learning leads to less conceptual and structural alignment between participants than observed for those in the interactive condition. The paper concludes with a comparison of the two accounts in relation to how each promotes signs that are effi cient, systematic and learnable. (shrink)

Our target article proposed that language production and comprehension are interwoven, with speakers making predictions of their own utterances and comprehenders making predictions of other people's utterances at different linguistic levels. Here, we respond to comments about such issues as cognitive architecture and its neural basis, learning and development, monitoring, the nature of forward models, communicative intentions, and dialogue.

Pierre Viret (1511–1571), one of the leaders of the Calvinist Reformation, claims that the natural theology of his Instruction Chrestienne (1564) dedicated to the Faculty of Medicine of Montpellier, is a spiritual medicine. This paper shows that such spiritual medicine amounts to a specific expression of Calvinist pastoralism. Viret's natural theology uses natural-historical data as moral examples, thus transforming them into the material fit for his pastoral cure. This cure consists in exhorting his audience to bear the trials of divine (...) Providence by meditating on their own sinful state: such medicine asserts the limits of human reason. (shrink)

Foundations of Language sets out to reconcile generative accounts of language structure with psychological accounts of language processing. We argue that Jackendoff's “parallel architecture” is a particularly appropriate linguistic framework for the interactive alignment account of dialogue processing. It offers a helpful definition of linguistic levels of representation, it gives an interesting account of routine expressions, and it supports radical incrementality in processing.

Since P. Thielscher, in Philologus, 1907, pp. 117, 128, supplies us with information about the Manilian MS. Palatinus 1711 , the importance of which he himself does not seem to comprehend, I should like to point out what an interesting MS. this is. ‘It is to be suspected,’ says Thielscher, ‘that it offers interpolated readings.’ It is not a matter of ‘suspicion’ at all. If Thielscher did not know it for himself, he could have learnt from Scaliger , from Bentley, (...) from Jacob, that the readings of P long ago received sufficient publicity to enable scholars to assign it to the ‘ interpolated’ class of MSS. The Variae Lectiones of Junius is mostly occupied with the readings of P, and tells us all about P that we need know, save what Thielscher has himself added. From Thielscher we for the first time learn that P belonged to ‘Johannes Archiepiscopus Strigoniensis,’ and that it contains this subscription: ‘legi et emendaui cum magistro Galeotto 1469.’ Now just as Thielscher seems to know nothing of Junius, so he seems to have no idea who Johannes Strigoniensis is, though the reference to Galeotto and the year 1469 should at once have told him. If he had troubled to look at Schmitt's Archiepiscopi he would have found that, while Schmitth enumerates no less than six archbishops of Gran who bore the name John, yet the only one of them who fits the date 1469 is John IV. And John IV. is a famous person, being none other than that leader of the Hungarian Renaissance whom we commonly call Vitezius. (shrink)

In the Classical Quarterly, vol. ii. No. 2, reviewing Breiter's recent text of the Astronomica, together with Housman's edition of Book i, I made a number of suggestions of my own on some of the principal difficulties in the text and interpretation of Manilius. I did not, however, bring my notes down beyond Book i. In the present paper I propose to traverse some of the more thorny places of ii. and iii. I shall try to make what I have (...) to say to some extent a continued review of Breiter. (shrink)

My paper, written in 1911, was something of a ballon d'essai, and I acknowledge frankly one or two mistakes. Thus I did not know that Euripides wrote a Thyestes; and again one or two of my references were wrong: in excuse I may perhaps plead that I have not had access to a Latin book for nearly two years. Apart from this I will now make only two observations:1. I set aside the evidence of Cod. Paris. Lat. 7530 because I (...) was dealing with evidence of saec. i.-iv. Cod. Paris. Lat. 7530 shows that some persons at the end of saec. viii. ascribed the Thyestes to L. Varius Rufus. So did persons in saec. iv. In addition, Cod. Paris. Lat. 7530 gives a date for the Thyestes. To Mr. Housmanthis date is certain; if it is uncertain a large part of his argument comes to nothing. But who can think it certain ? It comes to us from the end of the eighth century. If it came to us from Jerome's Chronicle we could still not think it certain, though we should know whence Jerome derived it. We do not now whence Cod. Paris. Lat. 7530 derived it. The reference to Actium may have no better source than the wish to connect a great literary and a great political event: and the gossip about the playwright's profits seems to me in itself suspicious.2. The main contention of the early part of my paper was that the evidence of the relevant MSS. as between Vari and Varii, etc., amounts to nothing either way. I do not think Mr. Housman is prepared seriously to contest this proposition. (shrink)

A good edition of the Catalepton has long been wanted: and Birt's recently Published ‘Erklärung,’ despite some obvious defects, may fairly be regarded as good book. It is at any rate fresh, interesting, and stimulating. The text is the whole, though not always, sensible. The commentary is full without being too full. But, more valuable still, both commentary and introduction constantly bring home to one the probability that nearly all the poems in this collection are genuinely Vergilian— ‘Jugendverse und Heimatpoesie (...) Vergils.’ No editor before Birt has brought before us so clearly the environment out of which these poems came. (shrink)

Desmosomes are junctions involved in intercellular adhesion of epithelial cells and hemidesmosomes are junctions involved in adhesion of epithelia to basement membranes. Both are characterised at the ultrastructural level by dense cytoplasmic plaques which are linked to the intermediate filament cytoskeleton of the cells. The plaques strongly resemble each other suggesting a relationship between the two kinds of junctions, as implied by their names. Recent characterisation of the molecular components of the junctions shows they are, in fact, quite unrelated implying (...) that structural similarity is fortuitous. The molecular biology raises many fascinating problems relating to their structure and function. (shrink)

Many authors have recently highlighted the importance of prediction for language comprehension. Pickering & Garrod (P&G) are the first to propose a central role for prediction in language production. This is an intriguing idea, but it is not clear what it means for speakers to predict their own utterances, and how prediction during production can be empirically distinguished from production proper.

Interactive theories of lexical retrieval in language production assume that activation cascades from earlier to later processing levels, and feeds back in the reverse direction. This commentary invites Pickering & Garrod (P&G) to consider whether cascading and feedback can be seen as a form of forwarding modeling within a hierarchical production system.

Pickering & Garrod's (P&G's) mechanistic theory of dialogue attempts to detail the psychological processes involved in communication that are lacking in Clark's theory. By relying on automatic priming and alignment processes, however, the theory falters when it comes to explaining much of dialogic interaction. We argue for the inclusion of less automatic, though not completely conscious and deliberate, processes to explain such phenomena.

Although applauding Pickering & Garrod's (P&G's) attempt to ground language use in the ideomotor perception-action link, which provides an of embodied social interaction, we suggest that it needs to be complemented by an additional control mechanism that modulates its operation in the service of the language users' communicative intentions. Implications for intergroup relationships and intercultural communication are discussed.

Starting from the conceptual premises of Garrod, who as long ago as 1902 spoke of chemical individuality, and of Burnet (1949), who recognized as self one's own molecular antigenic structures (as opposed to the antigenic alien: the non- self), the discovery and understanding of HLA antigens and of their extraordinarily individual and differentiated polymorphisms have gained universal recognition. Transplant medicine has now dramatically stressed, within man's knowledge of himself, the characteristic of his biological uniqueness. Today man, having become aware (...) of being a biological antigenic-molecular individuality which is unique and different from that of all of his fellow men (except for monozygotic twins), can therefore easily consider himself a true biological Ego.

A historically-informed account of the lasting importance of embodied thought in the intellectual trajectory of René Descartes, still remembered today as the founding father of dualism.

Currently, production and comprehension are regarded as quite distinct in accounts of language processing. In rejecting this dichotomy, we instead assert that producing and understanding are interwoven, and that this interweaving is what enables people to predict themselves and each other. We start by noting that production and comprehension are forms of action and action perception. We then consider the evidence for interweaving in action, action perception, and joint action, and explain such evidence in terms of prediction. Specifically, we assume (...) that actors construct forward models of their actions before they execute those actions, and that perceivers of others' actions covertly imitate those actions, then construct forward models of those actions. We use these accounts of action, action perception, and joint action to develop accounts of production, comprehension, and interactive language. Importantly, they incorporate well-defined levels of linguistic representation. We show how speakers and comprehenders use covert imitation and forward modeling to make predictions at these levels of representation, how they interweave production and comprehension processes, and how they use these predictions to monitor the upcoming utterances. We show how these accounts explain a range of behavioral and neuroscientific data on language processing and discuss some of the implications of our proposal. (shrink)

Traditional mechanistic accounts of language processing derive almost entirely from the study of monologue. Yet, the most natural and basic form of language use is dialogue. As a result, these accounts may only offer limited theories of the mechanisms that underlie language processing in general. We propose a mechanistic account of dialogue, the interactive alignment account, and use it to derive a number of predictions about basic language processes. The account assumes that, in dialogue, the linguistic representations employed by the (...) interlocutors become aligned at many levels, as a result of a largely automatic process. This process greatly simplifies production and comprehension in dialogue. After considering the evidence for the interactive alignment model, we concentrate on three aspects of processing that follow from it. It makes use of a simple interactive inference mechanism, enables the development of local dialogue routines that greatly simplify language processing, and explains the origins of self-monitoring in production. We consider the need for a grammatical framework that is designed to deal with language in dialogue rather than monologue, and discuss a range of implications of the account. Key Words: common ground; dialogue; dialogue routines; language comprehension; language production; monitoring; perception-behavior link. (shrink)

How might a human communication system be bootstrapped in the absence of conventional language? We argue that motivated signs play an important role (i.e., signs that are linked to meaning by structural resemblance or by natural association). An experimental study is then reported in which participants try to communicate a range of pre-specified items to a partner using repeated non-linguistic vocalization, repeated gesture, or repeated non-linguistic vocalization plus gesture (but without using their existing language system). Gesture proved more effective (measured (...) by communication success) and more efficient (measured by the time taken to communicate) than non-linguistic vocalization across a range of item categories (emotion, object, and action). Combining gesture and vocalization did not improve performance beyond gesture alone. We experimentally demonstrate that gesture is a more effective means of bootstrapping a human communication system. We argue that gesture outperforms non-linguistic vocalization because it lends itself more naturally to the production of motivated signs. (shrink)

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants’ horizontal, pair‐wise interactions led (...) “bottom up” to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community‐evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.

Epithelia can be defined morphologically as tissues that line surfaces, and ultrastructurally with reference to their cells' apico‐basal polarity and possession of specific cell‐cell junctions. Defining the epithelial phenotype at a molecular level is more problematic ‐ while it is easy to name proteins (e.g. keratins) expressed by a “typical” epithelium, no known molecules are expressed by every epithelium but by no other tissues. Cells can differentiate to and from the epithelial state as part of normal development, as a response (...) to disease or when manipulated in culture. Many factors (matrix components, adhesion molecules, growth factors, transcription factors) have been identified that can trigger these transitions of phenotype in specific cases, but to date no general master regulators of the epithelial state have been found. The epithelial state may therefore be controlled by multiple regulatory genes so that there is no single molecule responsible for all of the diverse types of epithelium that exist in higher animals.
