In this article we study how members of an interdisciplinary research team use an online forum for communicating about their research project. We use the concepts of "community of practice" and "connectivity" to consider the online interaction within a wider question of how people from different academic traditions "do" interdisciplinarity. The online forum for this Grey and Pleasant Land project did not take off as hoped, even after a series of interventions and amendments, and we consider what the barriers (...) were and how they might be overcome. Barriers to involvement included participants' expectations of interaction and collaboration--expectation that real interaction happens elsewhere, tensions between academic discourse and forum talk norms, unfamiliarity with the technology, and different conceptions of appropriate academic discussion. We suggest that common academic practice does not prepare us well for creating interdisciplinary research communities through online collaboration tools, whereas such tools are our best bet currently for including geographically dispersed members in collaborative projects. Therefore, careful planning and competence building would be necessary if such tools are to be used in collaborative research. Suggested interventions, based on our experience, include providing a more focused forum, making technical support easily available, and setting up particular tasks or items to debate, within a preset, synchronous timeframe, focusing on issues relevant to the project at that time.

Interactomics aims to characterize all interactions formed between molecules that comprise our body. Although it emerged from quantitative biophysics, it has devolved into a predominantly qualitative field of science over the past decades. Due to technical limitations at its onset, almost all tools in interactomics are qualitative, which persists in defining the discipline. Here, we argue that interactomics needs to return to a quantitative direction because the technical achievements of the last decade have overcome the original limitations that forced its (...) current path. In contrast to qualitative interactomics which is constrained to charting lists of observed interactions, quantitative interactomics can also uncover answers to key questions such as the strength of interactions or how many of certain complexes can form in cells, thus providing researchers with more immediate proxies for understanding and predicting biological processes.

Research on brain or cognitive/affective processes, culture, social interaction, and structural analysis are overlapping but often independent ways humans have attempted to understand the origins of their evolution, historical, and contemporary development. Each level seeks to employ its own theoretical concepts and methods for depicting human nature and categorizing objects and events in the world, and often relies on different sources of evidence to support theoretical claims. Each level makes reference to different temporal bandwidths (milliseconds, seconds, minutes, hours, days, (...) months, years, decades, and centuries) and focuses on different spatio-temporal activities and controlled and non-controlled stimulus conditions. Biological mechanisms and environmental pressures for survival simultaneously created a gradual intersection and enhancement of cognitive/affective skills, cultural practices, and changes in collaborative social interaction and communicative skills. The evolution of a given level of analysis is assumed to have been incremental and overlapping. These innovative and independent ways humans have learned to characterize their brain or cognitive/affective and social/economic/political life often depend on unexamined, representational re-descriptions or cognitive/affective and socio-cultural devices and forms of communication that facilitate the depiction of practices and beliefs we attribute to respondents or subjects and research colleagues.

Coastal environments are widely recognized as valuable public health resources and therapeutic landscapes. However, limited research has examined how specific coastal interactions that foster close connections with nature influence health outcomes. This study investigates the relationship between the frequency of engaging in high-nature-interaction coastal activities―e.g., beach walking, wildlife spotting, water sports, mountain biking, spending time on the beach, beach sports, watching the sunset, seagoing, and shell collecting― and health outcomes among visitors to the Belgian coast. Using a dataset of (...) 1,939 responses, we analyze how the frequencies of these activities over the past year are associated with self-reported mental and general health. Grounded in the Granular Interaction Thinking Theory (GITT) and employing Bayesian GITT Framework analytics, the study identifies distinct patterns in these associations. While frequent engagement in activities, e.g., beach walking and beach sports, is positively linked to both mental and general health, spending time on the beach and shell collecting are unexpectedly associated with negative health outcomes. Watching the sunset is negatively associated with general health, while mountain biking and water sports show negative associations with mental health. In contrast, wildlife spotting exhibits a positive association with mental well-being. These findings highlight the complex interplay of environmental factors, visitor perceptions, and biophysical-psychological interactions in shaping health outcomes. The study emphasizes the need for targeted coastal management strategies to enhance the therapeutic benefits of blue spaces and calls for further research to elucidate the mechanisms underlying these associations.

Computational modeling and eye-tracking were used to investigate how phonological and semantic information interact to influence the time course of spoken word recognition. We extended our recent models to account for new evidence that competition among phonological neighbors influences activation of semantically related concepts during spoken word recognition . The model made a novel prediction: Semantic input modulates the effect of phonological neighbors on target word processing, producing an approximately inverted-U-shaped pattern with a high phonological density advantage at an intermediate (...) level of semantic input—in contrast to the typical disadvantage for high phonological density words in spoken word recognition. This prediction was confirmed with a new analysis of the Apfelbaum et al. data and in a visual world paradigm experiment with preview duration serving as a manipulation of strength of semantic input. These results are consistent with our previous claim that strongly active neighbors produce net inhibitory effects and weakly active neighbors produce net facilitative effects. (shrink)

This article explicates the interaction between implicit and explicit processes in skill learning, in contrast to the tendency of researchers to study each type in isolation. It highlights various effects of the interaction on learning (including synergy effects). The authors argue for an integrated model of skill learning that takes into account both implicit and explicit processes. Moreover, they argue for a bottom-up approach (first learning implicit knowledge and then explicit knowledge) in the integrated model. A variety (...) of qualitative data can be accounted for by the approach. A computational model, CLARION, is then used to simulate a range of quantitative data. The results demonstrate the plausibility of the model, which provides a new perspective on skill learning. (PsycINFO Database Record (c) 2012 APA, all rights reserved). (shrink)

Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions Under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrasts associated with color contrast interact with relative height in the visual field, partial occlusion, and interposition in determining the probability that a given figure is perceived as ‘‘nearer’’ than another. Latencies of ‘‘near’’ responses were analyzed to test for effects of (...) attentional selection. Figures in a pair were supported by luminance contrast or isoluminant color contrast and combined with one of the three geometric cues. The results of Experiment 1 show that luminance contrasts associated with hue, when it does not interact with other hues, produces the same effects as achromatic luminance contrasts: The probability of‘‘near’’ increases with luminance contrast while the latencies for ‘‘near’’ responses decrease. Partial occlusion is found to be a strong enough pictorial cue to support a weaker red luminance contrast. Interposition cues lose out against cues of spatial position and partial occlusion. The results of Experiment 2, with isoluminant displays of varying color contrast, reveal that red color contrast on a light background supported by any of the three geometric cues wins over green or white supported by any of the three geometric cues. On a dark background, red color contrast supported by the interposition cue loses out against green or white color contrast supported by partial occlusion. These findings reveal that color is not an independent depth cue, but is strongly influenced by luminance contrast and stimulus geometry. Systematically shorter response latencies for stronger ‘‘near’’ percepts demonstrate that selective visual attention reliably detects the most likely depth cue combination in a given configuration.

The focus of this article is on nursing students' perceptions of interactional justice during student—staff nurse encounters. A descriptive survey using a combined questionnaire on interactional justice was used to collect the data. Reliability analysis for the theoretical dimensions of interactional justice revealed a Cronbach's alpha value greater than 0.70. The student nurses perceived staff nurses to be interactionally unjust during their contact with them. Significant differences were observed between interactional justice and some demographic characteristics of students. Fourth year students (...) perceived staff to provide better justifications for decisions that affect them than third and second year students. Although black students, in contrast to white students, perceived clinical staff as significantly more truthful, these results are inconclusive. Students who engage for longer periods of time in the clinical learning context perceived their relationships and how they are treated by clinical staff as more just. Recommendations for further research are made. (shrink)

This article examines how a molecular "solution" to an important biological problem-how is antibody diversity generated? was obtained in the 1970s. After the primarily biological clonal selection theory (CST) was accepted by 1967, immunologists developed several different contrasting theories to complete the SCST. To choose among these theories, immunology had to turn to the new molecular biology, first to nucleic acid hybridization and then to recombinant DNA technology. The research programs of Tonegawa and Leder that led to the "solution" are (...) discussed, and some of their strategies and heuristics are broadly characterized: (1) to what extent does the new recombinant DNA technology provide what the scientists claim is "direct evidence," what does that term mean, and what are the implications of that claim for biological "realism," and (2) is this episode one of reduction, partial reduction, or explanatory extension, and what do these terms mean in the context of a successful molecular "solution" to a biological problem.

In attempting to solve a wide variety of tasks, people naturally seek to modify their external environment such that the physical space in which they work is more amenable or ‘congenial’ to achieving a desired outcome. Attempts to determine the effectiveness of certain artifacts or spatial reorganizations in aiding reasoners solve problems must be relativised to the difficulty of the task and the cognitive abilities of the reasoners. These factors were examined using a simple word production task with letter tiles. (...) Two sets of tiles that differed in terms of word production difficulty were selected. Participants were asked to produce as many words as they could within a finite time period for each letter set. In one group, participants were encouraged to rearrange or touch the tiles when producing words, and in the other group, participants could not interact with or point to the tiles. Participants were further split in a low and high verbal fluency group as a function of their score on the Thurstone word fluency test taken at the end of the experiment. In the high fluency group, letter rearrangement did not improve the participants’ ability to generate words. In contrast, in the low verbal fluency group, letter rearrangement significantly enhanced the ability to produce new words from both the hard and easy letter set. For these participants, the task was more taxing and the opportunity to restructure the letter set substantially elevated their performance. The advantages of a distributed cognition analysis of this and other reasoning tasks are discussed. (shrink)

In the established space-time coordinate-transformation (STCT) interpretation of special relativity theory, relativistic changes are consequent upon the Lorentz transformation of coordinate clocks and rods between relatively moving systems. In the proposed alternative interpretation, relativistic changes occur only in association with physical interactions, and are direct alterations in the variables of the observed system. Since space-time and momentum-energy are conjugate four-vectors, transformation of a space or time variable of a system is to be expected only if there is a concomitant transformation (...) of the corresponding momentum or energy variable. The Lorentz invariance of the scalar entropy functionS supports the interaction interpretation; timet=f(S) of a macroscopic, entropy clock should give a Lorentz-invariant time measure, and an illustrative entropy clock is discussed. Noninteracting physical processes may be called Clausius processes, in contrast to Lorentz processes for which there is interaction and associated Lorentz transformation. Changes of energy and frequency, withE=hv, are instances of the parallel relativistic transformations. Likewise, the variation with velocity in decay time of mesons follows directly from the relativistic energy transformation of decay products; this relationship is shown for muons by a simple calculation with β-decay theory.

Problem solving in a materially rich environment requires interacting with chance. Sixty-four participants were invited to solve 5-letter anagrams presented as movable tiles in conditions that either allowed the participants to move the tiles as they wished or only allowed random shuffling (without rearranging the tiles post shuffling) thus contrasting pure luck with an interactive model. We hypothesised that shuffling would break unhelpful mental sets and introduce beneficial unplanned problem-solving trajectories. However, participants performed significantly worse when shuffling, which suggests luck (...) plays less of a role than has been previously suggested. Granular analysis of seven critical cases revealed arbitrary path dependency across both conditions and moments of missed luck. It also questions current models of non-agentic luck and the ability to separate agent and luck. This research has implications for fostering better problem solving in an uncertain and fluid world.

Category-specific impairments of object recognition and naming are among the most intriguing disorders in neuropsychology, affecting the retrieval of knowledge about either living or nonliving things. They can give us insight into the nature of our representations of objects: Have we evolved different neural systems for recognizing different categories of object? What kinds of knowledge are important for recognizing particular objects? How does visual similarity within a category influence object recognition and representation? What is the nature of our semantic knowledge (...) about different objects? We review the evidence on category-specific impairments, arguing that deficits even for one class of object cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients. The same apparent pattern of impairment can be produced by damage to different loci. According to a new processing framework for object recognition and naming, the hierarchical interactive theory, we have a hierarchy of highly interactive stored representations. HIT explains the variety of patients in terms of lesions at different levels of processing and different forms of stored knowledge used both for particular tasks and for particular categories of object. Key Words: category-specific deficits; functional imaging; hierarchical models; interactive activation models; neuropsychology; object recognition; perceptual and functional knowledge. (shrink)

One may distinguish between three broad conceptions of linguistic meaning. One conception, which I will call “logical”, views meaning as given in reference (for words) and truth (for sentences). Another conception, the “monological” one, seeks meaning in the cognitive capacities of the single mind. A third, “dialogical”, conception attributes meaning to interaction between individuals and personal perspectives. In this chapter I directly contrast how well these three approaches deal with the evidence brought forth by fictive interaction. I (...) examine instances of fictive interaction and argue that intersubjectivity in these instances cannot be reduced to either referential-logical or individual-cognitive semantic notions. It follows that intersubjectivity must belong to the essence of linguistic meaning. (shrink)

Context: Distributed language and interactivity are central members of a set of concepts that are rapidly developing into rigorous, exciting additions to 4E cognitive science. Because they share certain assumptions and methodological commitments with enactivism, the two have sometimes been confused; additionally, while enactivism is a well-developed paradigm, interactivity has relied more on methodological development and on a set of focal examples. Problem: The goal of this article is to clarify the core conceptual commitments of both interactivity-based and enactive approaches (...) to cognitive science by contrasting the two and highlighting their differences in assumptions, focus, and explanatory strategies. Method: We begin with the shared commitments of interactivity and enactivism - e.g., antirepresentationalism, naturalism, interdisciplinarity, the importance of biology, etc. We then give an overview of several important varieties of enactivism, including sensorimotor and anti-representationalist enactivism, and then walk through the history of the “core” varieties, taking care to contrast Maturana’s approach with that of Varela and the current researchers following in Varela’s footsteps. We then describe the differences between this latter group and interactivity-based approaches to cognitive science. Results: We argue that enactivism’s core concepts are explanatorily inadequate in two ways. First, they mis-portray the organization of many living systems, which are not operationally closed. Second, they fail to realize that most epistemic activity depends on engagement with non-local resources. Both problems can be dealt with by adopting an interactivity-based perspective, in which agency and cognition are fundamentally distributed and involve integration of non-local resources into the local coupling of organism and environment. Implications: The article’s primary goal is theoretical clarification and exposition; its primary implication is that enactive concepts need to be modified or extended in some way in order to explain fully many aspects of cognition and directed biological activity. Or, read another way, the article’s primary implication is that interactivity already provides a rich set of concepts for doing just that, which, while closely allied with enactivism in several ways, are not enactivist concepts. Constructivist content: The article consists entirely of a comparison between two constructivist fields of theory. Key Words: Interactivity, enactivism, distributed language, radical embodied cognitive science, ecological psychology, autonomy. (shrink)

We argue that progress in our scientific understanding of the ‘social mind’ is hampered by a number of unfounded assumptions. We single out the widely shared assumption that social behavior depends solely on the capacities of an individual agent. In contrast, both developmental and phenomenological studies suggest that the personal-level capacity for detached ‘social cognition’ is a secondary achievement that is dependent on more immediate processes of embodied social interaction. We draw on the enactive approach to cognitive science (...) to further clarify this strong notion of ‘social interaction’ in theoretical terms. In addition, we indicate how this interaction theory could eventually be formalized with the help of a dynamical systems perspective on the interaction process, especially by making use of evolutionary robotics modeling. We conclude that bringing together the methods and insights of developmental, phenomenological, enactive and dynamical approaches to social interaction can provide a promising framework for future research. Keywords: theory of mind; cognitive science; phenomenology; embodied cognition; dynamical systems theory; enactive approach; social cognition; interaction theory; evolutionary robotics. (shrink)

Meetings differ from ordinary conversation in that they have an agenda that specifies in advance the topics to be addressed during the meeting. However, the introduction of these topics needs to be locally accomplished and recognized by the participants as agenda items. This article presents some characteristic practices used for introducing agenda-based topics. It shows that they rely on the known-in-advance status of the items, and are presented by the chair as unilateral announcements. They exploit and invoke the written agenda (...) in several ways. The announcements are often short phrasal constructions, just citing the written title of the agenda point. Furthermore, a gaze down at the written document is used as a public display that the introduction is related to the agenda. In contrast to this practice of introducing agenda items, topics not specified by the agenda are introduced by suggestions and questions that present the introduction as contingent on acceptance by the co-participants. The analysis sheds light on the ways in which institutional talk-in-interaction is permeated by the formulations and logic of written documents. (shrink)

Rom Harré has recently proposed that there is a difference between the driving force behind the early and the later Wittgenstein. According to Harré, in the early work, the major inspiration came from science, while, in the later, it came from religion. I show that only Harré’s first proposal is fully justified. In section one of my paper, I examine the picture theory, the theory of truth-functions, the meaning of propositions, and Tractatus §6.3. In section two, about the Philosophical Investigations, (...) I show that Harré is misleading. In a first step, I argue that science plays the same role in this later work as in the Tractatus, namely the role of source of inspiration. In a second step, I show that science plays also the role of a contrast against which the rich world of meaning can be discerned. I examine this contrastive role not only as regards religion, but also as regards psychology, and as regards the repercussions of Wittgenstein’s later work on science-studies. My final proposal is that the distinction between science as source of inspiration and science as a contrast goes beyond Wittgenstein: it characterises much twentieth century philosophical work in this area.

The structure of traditional fiction is essentially linear or serial. No matter how complex a given work may be, it presents information to its reader successively, one element at a time, in a sequence determined by its author. By contrast, interactive fiction is parallel in structure or, more accurately, dendritic or tree-shaped. Not one, but several possible courses of action are open to the reader. Further, which one actually happens depends largely, though not exclusively, upon the reader’s own choices. (...) To be sure, the author is still in overall control, since it is she who has set up the particular nexus of events, but the route up the narrative tree, the actual sequence of events, is generally affected, if not completely determined, by the reader’s responses to that particular reader’s specific situation. In an adventure, the sequence of action frequently depends upon the reader’s decision to go in one geographical direction rather than another. In the eliza sample, the content of the “story” depends on such particulars as whether this reader has a brother or not, whether she fears her father, and why she has consulted the terminal. In general, the text presented to the eliza-reader depends on what that reader has already said and how the computer has interpreted and stored it, and this is generally true of interactive fiction.Further, interactive fiction is, in principle , open-ended—infinite. A conversation with eliza could go on for as long as one with Woody Allen’s psychoanalyst—in principle, forever. It has no necessary terminus. The program will go one writing texts and answers on the screen as long as the reader or player chooses to supply responses. Further, the computer can act as a metafictional narrator like John Barth or Thomas Pynchon who can create a story within a story or a story that generates another story within itself which generates another story within itself and so on, fictions dizzying and dazzling. One senses one’s essential humanity wobbling in the midst of the infinite paradoxes of existence and meaning. Anthony J. Niesz, assistant professor of German at Yale University, is the author of Dramaturgy in German Drama: From Gryphius to Goethe .

Modulation of visual attention in the Visual World Paradigm relies on parallel processing of linguistic and visual information. Previous studies have argued that the human linguistic capacity includes an aspect of anticipation of upcoming material. Such anticipation can be triggered by both lexical and grammatical/morphosyntactic cues. In this study, we investigated the relationship between comprehension and prediction by testing how subtle changes in visual representations can affect the processing of grammatical case cues in Russian by Russian-German bilingual children (n = (...) 49, age 8−13). The linguistic manipulation followed previous designs, contrasting SVO and OVS sentences, where the first NP (NP1) was marked with nominative or accusative case, respectively. Three types of visual displays were compared: (i) individual referents (potential agent/theme); (ii) pairs of referents (NP1 + potential agent/theme); and (iii) events (representing interactions between the referents). Participants were significantly more sensitive to the case manipulation when presented with events compared to the other two types of visual display. This suggests that they were able to quickly integrate the thematic role information signaled by grammatical case in the event representations. However, they were less likely to use the case information to anticipate upcoming arguments when the target pictures represented individual referents or pairs of noninteracting referents. We hypothesize that the process of argument anticipation is mediated by the activation of syntactic templates (SVO or OSV, depending on the case marking on NP1). The relatively weak anticipation effect observed may be attributed to the absence, or weak representation, of the noncanonical OVS template in the bilingual children's long-term memory. (shrink)

Because the traditional social media fuzzy static image interactive three-dimensional (3D) reconstruction method has the problem of poor reconstruction completeness and long reconstruction time, the social media fuzzy static image interactive 3D reconstruction method is proposed. For preprocessing the fuzzy static image of social media, the Harris corner detection method is used to extract the feature points of the preprocessed fuzzy static image of social media. According to the extraction results, the parameter estimation algorithm of contrast divergence is used (...) to learn the restricted Boltzmann machine (RBM) network model, and the RBM network model is divided into input, output, and hidden layers. By combining the RBM-based joint dictionary learning method and a sparse representation model, an interactive 3D reconstruction of fuzzy static images in social media is achieved. Experimental results based on the CAD software show that the proposed method has a reconstruction completeness of above 95% and the reconstruction time is less than 15 s, improving the completeness and efficiency of the reconstruction, effectively reconstructing the fuzzy static images in social media, and increasing the sense of reality of social media images.

Introduction Social anxiety disorder (SAD) symptoms are maintained by cognitive biases, which are overestimations of the severity and likelihood of negative social events (cost/probability biases), and by sensitivity to rewards and punishments that are determined according to behavioral inhibition/behavioral activation systems (BIS/BAS). Cost/probability biases might activate the behavioral immune system and exacerbate the avoidance of social events. Earlier studies have proposed that low BIS or high BAS decrease SAD symptoms; BIS/BAS may even change the effects of cognitive biases on SAD (...) symptoms. Hence, the current study investigates the interaction effects of BIS/BAS and cost/probability biases on SAD symptoms. Method Seventy-six Japanese undergraduate students completed the Japanese version of the Liebowitz Social Anxiety Scale (LSAS), which comprises Fear and Avoidance subscales, the BIS/BAS Scale, and the Social Cost Probability Scale. Results A multiple regression analysis was performed to examine whether cost/probability biases, BIS/BAS, and their interactions affected SAD symptoms; following this, the main effects of cost bias and BIS were determined for LSAS-Fear (β =.64, p <.001; β =.33, p <.01) and LSAS-Avoidance (β =.49, p <.001; β =.35, p <.01). The interaction effect between cost bias and BAS was significant for LSAS-Avoidance (β = −.32, p <.05). Simple slope analysis showed that the slope of cost bias was significant for low-BAS individuals (β =.77, p <.001) but not for high-BAS individuals (β = −.21, n.s.). The interaction effect between probability bias and BAS was significant for LSAS-Avoidance (β =.40, p <.01) as well. Further, simple slope analysis revealed that the slope of probability bias was significant for low-BAS individuals (β = −.53, p <.05) but not for high-BAS individuals (β =.17, n.s.). Discussion The study found interesting results with respect to the avoidance of social events. Low-BAS individuals with high cost or low probability biases regarding social events may have a tendency to avoid social events. In contrast, if high-BAS individuals overestimate the cost of social events or underestimate the probability of social events, their anticipation of rewards might prevent them from avoiding social events.

Open peer commentary on the article “Interactivity and Enaction in Human Cognition” by Matthew Isaac Harvey, Rasmus Gahrn-Andersen & Sune Vork Steffensen. Upshot: Enaction is a diverse research program and some of its texts can be interpreted in terms of a critical contrast to interactivity. Yet much of the former has already started to move in a direction favored by the latter: toward systematic studies of how human activity is shaped by social, cultural, and technological influences. Interactivity could therefore (...) help enaction to provide a better account of such highly mediated and augmented forms of sense-making. (shrink)

Large tracts of European rural land, mostly in the less favored areas (LFA), are devoted to low-inputs and large scale grazing systems (LSGS) with potential environmental and social functions. Although these LSGS may provide harbor for a good part of European nature values, their continuity is facing contrasting threats of intensification and abandonment. These areas, however, may be characterized by particular grazing structures and social dynamics of change that should be unveiled prior to attempts to devise rural development strategies or (...) to adapt policy frameworks in general. To wit, stakeholder interactions and legal and institutional processes are described and analyzed for the cereal-sheep system of Castile-La Mancha (CLM) in the central Iberian plain. Farmers and pastoralists still share the use of the land, but their roles and interests have changed over time, and particularly in the last 50 years. Arable farming, mainly cereal cropping, has followed an intensification path, partially tempered by the environmental constraints of the Castilian plain. Extensive pastoralism is still a secondary option of land use; in the main, sheep farmers depend on, and look to, the management practices of arable farmers. A mixed cereal and sheep operation may deliver environmental and economic benefits, but successful implementation of this strategy is only possible when the system serves the needs of both types of stakeholders. Paradoxically, the main drivers of change in the countryside overall are arrayed against this sensible and traditional agricultural system. We argue that the recent legal and institutional frameworks do not favor social cohesion and that policy-support schemes of the European Union (EU) have been, and continue to be, devised without taking into account the particular structures and social dynamic of the farming system.

We propose a model of reference that contrasts with standard linguistic approaches in that it focuses on the role of interaction in reference, arguing that referring expressions in conversations are not designed for interchangeable audiences but rather exploit the common ground between partners. Our model also differs from psycholinguistic approaches in that it uses conversational data, since critical aspects of natural conversations are absent from laboratory tasks used so far and thus are not captured by current models. Examples from (...) conversations are presented to demonstrate that speakers often try to manage the accessibility of a problematic referent to an addressee by presenting a context for it as well as a referring expression, even at the cost of syntactic orthodoxy. We also present examples demonstrating that partners negotiate as to what representation is good enough for present purposes and whether that has been achieved. While strategies may vary as to explicitness, we believe these negotiations underlie all formulations of referring expressions. (shrink)

Over the lifetime of Conversation Analysis (CA), scholars have discovered many systems of action organisation (machineries) describing how conversational turns occur, what actions are expected, and how intersubjectivity in conversation is maintained. However, when John Heritage proposed a new machinery that examines the knowledge orientation of participants in interactions, a debate broke out between conversation analysts in which Michael Lynch and his colleagues in radical ethnomethodology descend upon on epistemics. The controversy begins with Lynch accusing Heritage of cognitivism and the (...) extra-situational nature of epistemics, while research on ethnomethodology and conversation analysis has traditionally focused on situated action. The discussion of epistemics points to an internal tension in CA as to where the boundaries of situations lie and what, therefore, can be the focus of CA. This article reactualises the problem of situationality in CA by analysing the arguments in the debate on epistemics. The authors show that epistemics and the debates surrounding it constitute a serious test for CA, revealing a conceptual problem that has hitherto been obscured - the relation and potential hierarchy of different machineries. Turning to the origins of the concept of situationality in the writings of Goffman and Sacks, the authors demonstrate that for opposing sides, the localisation of phenomena within situations is an analytical decision about what can be seen in empirical data. In contrast, distinguishing between the position of the analyst and the participant in the interaction shifts the analyst's attention to how the machineries become relevant to the interactants, that is, how their omnirelevance is realised. The authors argue that this is a more productive formulation of the question than that of the boundaries of the situation. (shrink)

L(ow) tone in Mandarin Chinese causes both downstep and post-low-bouncing. Downstep refers to the lowering of a H(igh) tone after a L tone, which is usually measured by comparing the H tones in a “H…HLH…H” sentence with a “H…HHH…H” sentence (cross-comparison), investigating whether downstep sets a new pitch register for the scaling of subsequent tones. Post-low-bouncing refers to the raising of a H tone after a focused L tone. The current study investigates how downstep and post-low-bouncing interact with focus and (...) phrasing in Mandarin Chinese. In the experiment, we systematically manipulated (a) the tonal environment by embedding two syllables with either LH or HH tone (syllable X and Y) sentence-medially in the same carrier sentences containing only H tones; (b) boundary strength between X and Y by introducing either a syllable boundary or a phonological phrase boundary; and (c) information structure by either placing a contrastive focus in the HL/HH word (XF), syllable Y (YF), or the sentence-final word (ZF). A wide-focus condition served as the baseline. With systematic control of focus and boundary strength around the L tone, the current study shows that the downstep effect in Mandarin is quite robust, lasting for 3–5 H tones after the L tone, but eventually levelling back again to the register reference line of a H tone. The way how focus and phrasing interact with the downstep effect is unexpected. Firstly, sentence-final focus has no anticipatory effect on shortening the downstep effect; instead, it makes the downstep effect lasts longer as compared to the wide focus condition. Secondly, the downstep effect still shows when the H tone after the L tone is on-focus (YF), in a weaker manner than the wide focus condition, and is overridden by the post-focus-compression. Thirdly, the downstep effect gets greater when the boundary after the L tone is stronger, because the L tone is longer and more likely to be creaky. We further analyzed downstep by measuring the F0 drop between the two H tones surrounding the L tone (sequential-comparison). Comparing it with F0 drop in all-H sentences (i.e., declination), it showed that the downstep effect was much greater and more robust than declination. However, creaky voice in the L tone was not the direct cause of downstep. At last, when the L tone was under focus (XF), it caused a post-low-bouncing effect, which is weakened by a phonological phrase boundary. Altogether, the results showed that although intonation is largely controlled by informative functions, the physical-articulatory controls are relatively persistent, varying within the pitch range of 2.5 semitones. Downstep and post-low-bouncing in Mandarin Chinese thus seem to be mainly due to physical-articulatory movement on varying pitch, with the gradual tonal F0 change meeting the requirement of smooth transition across syllables, and avoiding confusion in informative F0 control.

This chapter begins with an empirical analysis of attitudes towards the law, which, in turn, inspires a philosophical re-examination of the moral status of the rule of law. In Section 2, we empirically analyse relevant survey data from the US. Although the survey, and the completion of our study, preceded the recent anti-police brutality protests sparked by the killing of George Floyd, the relevance of our observations extends to this recent development and its likely reverberations. Consistently with prior studies, we (...) find that people’s ascriptions of legitimacy to the legal system are predicted strongly by their perceptions of the procedural justice and lawfulness of police and court officials’ action. Two factors emerge as significant predictors of people’s compliance with the law: (i) their belief that they have a (content-independent, moral) duty to obey the law (which is one element of legitimacy, as defined here); and (ii) their moral assessment of the content of specific legal requirements (‘perceived moral content of laws’). We also observe an interactive relationship between these two factors. At higher levels of perceived moral content of laws, felt duty to obey is a better predictor of compliance. And, similarly, perceived moral content of laws is a better predictor of compliance at higher levels of felt duty to obey. This suggests that the moral content incorporated in specific laws interacts with the normative force people ascribe to legal authorities by virtue of other qualities, specifically here procedural justice and lawfulness. In Section 3, the focus shifts to a philosophical analysis, whereby we identify a parallel (similarly interactive) modality in the way that form and content mutually affect the value of the rule of law. We advocate a distinctive alternative to two rival approaches in jurisprudential discourse, the first of which claims that Lon Fuller’s eight precepts of legality embody moral qualities not contingent on the law’s content, while the second denies any independent moral value in these eight precepts, viewing them as entirely subservient to the law’s substantive goals. In contrast, on the view put forward here, Fuller’s principles possess (inter alia) an expressive moral quality, but their expressive effect does not materialise in isolation from other, contextual factors. In particular, the extent to which it materialises is partly sensitive to the moral quality of the law’s content. (shrink)

In the past, notions of embodiment have been applied to robotics mainly in the realm of very simple robots, and supporting low-level mechanisms such as dynamics and navigation. In contrast, most human-like, interactive, and socially adept robotic systems turn away from embodiment and use amodal, symbolic, and modular approaches to cognition and interaction. At the same time, recent research in Embodied Cognition (EC) is spanning an increasing number of complex cognitive processes, including language, nonverbal communication, learning, and social (...) behavior.This article suggests adopting a modern EC approach for autonomous robots interacting with humans. In particular, we present three core principles from EC that may be applicable to such robots: (a) modal perceptual representation, (b) action/perception and action/cognition integration, and (c) a simulation-based model of top-down perceptual biasing. We describe a computational framework based on these principles, and its implementation on two physical robots. This could provide a new paradigm for embodied human–robot interaction based on recent psychological and neurological findings. (shrink)

Standard models of concept learning generally focus on deriving statistical properties of a category based on data (i.e., category members and the features that describe them) but fail to give appropriate weight to the contact between people's intuitive theories and these data. Two experiments explored the role of people's prior knowledge or intuitive theories on category learning by manipulating the labels associated with the category. Learning differed dramatically when categories of children's drawings were meaningfully labeled (e.g., “done by creative children”) (...) compared to when they were labeled in a neutral manner. When categories are meaningfully labeled, people bring intuitive theories to the learning context. Learning then involves a process in which people search for evidence in the data that supports abstract features or hypotheses that have been activated by the intuitive theories. In contrast, when categories are labeled in a neutral manner, people search for simple features that distinguish one category from another. Importantly, the final study suggests that learning involves an interaction of people's intuitive theories with data, in which theories and data mutually influence each other. The results strongly suggest that straight‐forward, relatively modular ways of incorporating prior knowledge into models of category learning are inadequate. More telling, the results suggest that standard models may have fundamental limitations. We outline a speculative model of learning in which the interaction of theory and data is tightly coupled. The article concludes by comparing the results to recent artificial intelligence systems that use prior knowledge during learning. (shrink)

Academic bioethics does not appear to be interested in communication and its ethical concerns unless communication is to do with issues such as capacity, consent, truth telling and confidentiality. In contrast practitioners are interested in actually communicating with their patients and they are often particularly perplexed when it comes to people with profound disabilities where communication appears disrupted. Although some new and not so new communication strategies, and especially intensive interaction, are available, little has been written on either (...) the ethical concerns these may present or the deeper concepts that underpin them. This article explores the practical applications of some of these communication strategies. By engaging these strategies with theology, and specifically Pope John Paul’s Theology of the Body, this article identifies and addresses some significant ethical issues that may arise, notably the risk of dualism and of objectifying the human person. Moreover it provides communication strategies with a rationale that goes beyond practicalities to one based on respect for human dignity, justice and solidarity. (shrink)

Background: The classical symptom specificity hypothesis (Blatt, 1974) links obsessional symptoms to autonomous interpersonal behavior. Inconsistent findings from cross-sectional group studies on symptom specificity have previously been associated with several conceptual and methodological limitations intrinsic to nomothetic research. Previous empirical case research reported ambivalences between autonomous and dependent interpersonal behavior in obsessional pathology. Aim and Method: The present ‘theory-building’ case study specifically aims at further refinement of the classical symptom specificity hypothesis by testing specific operationalizations within an empirical single case (...) design. Consensual Qualitative Research for Case studies is used to quantitatively and qualitatively describe the longitudinal, clinical interplay between obsessional symptoms and interpersonal dynamics throughout the process of a psychodynamic therapy. Interpersonal functioning is assessed by means of the Core Conflictual Relationship Theme method. The classical symptom specificity hypothesis is contrasted to an alternative hypothesis of interpersonal ambivalences as determinants of obsessional symptoms. Results: Close associations between obsessions and interpersonal dynamics are observed. Findings predominantly affirm the ambivalence hypothesis rather than the classical symptom specificity hypothesis. Psychodynamic interventions focusing on interpersonal conflicts are related to symptomatic changes. Conceptual and methodological considerations, limitations and future research indications are discussed. (shrink)

Philosophical and sociological approaches in technology have increasingly shifted toward describing AI (artificial intelligence) systems as ‘(moral) agents,’ while also attributing ‘agency’ to them. It is only in this way – so their principal argument goes – that the effects of technological components in a complex human-computer interaction can be understood sufficiently in phenomenological-descriptive and ethical-normative respects. By contrast, this article aims to demonstrate that an explanatory model only achieves a descriptively and normatively satisfactory result if the concepts (...) of ‘(moral) agent’ and ‘(moral) agency’ are exclusively related to human agents. Initially, the division between symbolic and sub-symbolic AI, the black box character of (deep) machine learning, and the complex relationship network in the provision and application of machine learning are outlined. Next, the ontological and action-theoretical basic assumptions of an ‘agency’ attribution regarding both the current teleology-naturalism debate and the explanatory model of actor network theory are examined. On this basis, the technical-philosophical approaches of Luciano Floridi, Deborah G. Johnson, and Peter-Paul Verbeek will all be critically discussed. Despite their different approaches, they tend to fully integrate computational behavior into their concept of ‘(moral) agency.’ By contrast, this essay recommends distinguishing conceptually between the different entities, causalities, and relationships in a human-computer interaction, arguing that this is the only way to do justice to both human responsibility and the moral significance and causality of computational behavior.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families (...) in Kikaikelaki, Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

In this paper I draw apart two different contexts of Freirean pedagogical practice that I label interactional and institutional. The interactional refers to the immediate learning environment with relation to the interaction between the students and the teacher. In contrast, the institutional refers to how the institutions of education are managed, constructed, and organised and how they relate to the individuals those institutions are composed of. I begin by presenting a brief overview of Freire’s argument in favour of (...) a revolutionary pedagogy. I then highlight how this project is represented at both interactional and institutional levels with a particular focus upon the practice of the revolutionary leaders and their role in the development of the humanisation of the oppressed. In presenting the interactional and institutional elements of Freire’s pedagogy separately the tension between the individual and the state is made plain and the limitations of his politico-educational project are drawn out. I argue that due to an inconsistent application of the relationship between means and ends in Freire’s politico-educational project an incoherence between the interactional and institutional levels of education is highlighted. In responding to this limitation of Freire’s politico-educational project with a thoroughly interconnected relationship of means and ends I show that there remains a necessary conflict between the interests of the individual and the state. As a result of this a door is opened for the development of an argument in favour of the disestablishment of education and state from a Freirean perspective. (shrink)

Taste is a central sense for humans and animals, and it has been largely studied either from physiological and neurological approaches or from socio-cultural ones. This paper adopts another view, focused on the activity of tasting rather than on the sense of taste, approached within the perspective of ethnomethodology and multimodal conversation analysis. This view addresses the activity of tasting as it is interactionally organized in specific social settings, observed in a naturalistic way, on the basis of video recordings. Focusing (...) on video recorded improvised tastings of cheese in gourmet shop encounters, the paper offers a systematic analysis of the way in which tasting is orderly achieved in an intersubjective way. It follows the various steps characterizing tasting, from the invitation to taste, to the grasping of a bit to taste, which is put in the mouth, chewed, and swallowed; it details how an interactional moment offering the taster a priviledged, individual, focused space in which to devote exclusive attention to the object tasted is actively tailored by all parties. By contrast, the completion of tasting is marked by a return to mutual gaze, the animation of facial expressions and nods, and the final production of a judgment of taste. By offering a systematic reconstruction of how these tasting moments are organized, the paper invites to a multimodal approach of sensoriality in social interaction. (shrink)

There is considerable debate among scholars over whether Descartes allowed for genuine body–body interaction. I begin by considering Michael Della Rocca’s recent claim that Descartes accepted such interaction, and that his doctrine of the creation of the eternal truths indicates how this interaction could be acceptable to him. Though I agree that Descartes was inclined to accept real bodily causes of motion, I differ from Della Rocca in emphasizing that his ontology ultimately does not allow for them. (...) This is not the end of the story, however, since two of Descartes’s successors offered incompatible ways of developing his conflicted account of motion. I contrast the occasionalist view of Nicolas Malebranche that changes in motion derive directly from divine volitions with the non-occasionalist claim of Pierre-Sylvain Regis that such changes derive from a nature distinct from God. In light of Della Rocca’s interpretation, it is noteworthy that the issue of eternal truths is relevant to both alternative accounts. Indeed, Regis took the doctrine that such truths are created to provide crucial support for his alternative to an occasionalist account of body–body interaction. What does not help Della Rocca, however, is that Regis’s view of motion requires a fundamental revision of Descartes’s ontology. Author Keywords: Descartes; Malebranche; Regis; Causation; Motion; Eternal Truths. (shrink)

Albert and De Ruiter provide an introduction to the Conversation Analytic approach to ‘repair’: the ways in which people detect and deal with troubles in speaking, hearing and understanding in conversation. They explain the basic turn‐taking structures involved, provide examples, explain recent developments in the field and highlight some important points of contact and contrast with work in the Cognitive Sciences.

Research has suggested that nostalgia is a mixed, albeit predominantly positive emotion. One proposed function of nostalgia is to attenuate the negative consequences of loneliness. This restorative effect of nostalgia, however, has been demonstrated with cross sectional and experimental methods that lack ecological validity. In studies that have measured nostalgia in daily life, however, nostalgia has been negatively related to well-being. We propose an alternative theory that posits that the effect of nostalgia on well-being depends on the event or experience (...) that elicits nostalgia. We tested this theory by measuring daily states of nostalgia, loneliness, and affect across five daily diary studies (N = 504; 6,004 daily reports) that lasted for 14 days. Using multilevel modeling, we found that nostalgia and loneliness were negatively related to positive affect and positively related to negative affect. The negative effects of nostalgia on affective well-being were significantly stronger on days when people felt more lonely as opposed to less lonely. Viewed alternatively, the negative effects of loneliness on affective well-being were stronger on days when people felt more vs. less nostalgic. Thus, in contrast to experimental findings, nostalgia did not attenuate, but rather exaggerated the negative effects of loneliness on affective well-being. These findings support a theoretical account that proposes that the effect of nostalgia on well-being depends on the natural context in which nostalgia is elicited. (shrink)

Concerning any object of philosophical analysis, we can ask several questions, including the two posed in the title of this paper. Despite difficulties in formulating a precise criterion to distinguish causal processes from pseudoprocesses, and causal interactions from mere spatiotemporal intersections, I argue that Salmon answered the first of these questions with extraordinary clarity. The second question, by contrast, has received very little attention. I will present two problems: in the first, it seems that Salmon has provided exactly the (...) conceptual resources needed to solve the problem; in the second, it is difficult to see how causal processes and interactions may be used to shed any light. In general, the way to carry Salmon's program forward will be to demonstrate that these resources can be made to do real philosophical work. (shrink)

First published in 2005, Economics and Social Interaction is a fresh attempt to overcome the traditional inability of economics to deal with interpersonal phenomena that occur within the sphere of markets and productive organizations. It makes use of traditional economic concepts for understanding interpersonal events, while venturing beyond those concepts to give a better account of personalised interactions. In contrast to other books, Economics and Social Interaction offers the reader a rigorous effort at extending economic analysis to (...) a difficult field in a consistent manner, sensitive to insights from other behavioural and social sciences. This collection represents an important contribution to a growing research agenda in the social sciences. (shrink)

In this paper, I propose a framework that supports both free will and anomalous mind-matter interaction (psychokinesis). I begin by considering the argument by the physicist Sean Carroll that the laws of physics as we understand them rule out psychokinesis (and other modes of psi). I find Carroll’s claims problematic, in part due to what I believe are misunderstandings of arguments borrowed from David Hume. I proceed to consider a more dispositional notion of causality (in contrast to one (...) characterized by universal and necessary laws) which I argue is more hospitable to both psychokinesis and free will. I then incorporate recent work from the philosophy of mind and science to arrive at a framework that supports both real volition and psychokinesis, which I argue are intimately linked. This approach is fundamentally dispositional, but grounded in an ontologically prior field of awareness and potentiality. I also consider that the regularities (or causal natures) we observe in our physical world are ultimately supported by what we might term teleological “intentions” within a nonlocal, mind-like quantum ground.

This article examines the practice of "co-participant completion" in Japanese conversation, and explores what kinds of resources are mobilized to provide the opportunity to complete another participant's utterance-in-progress. It suggests the following observations as potential characteristics of Japanese co-participant completion: (i) Syntactically-defined two-part formats (e.g. [If X] + [then Y]) may not play as prominent a role as in English; (ii) The majority of cases of co-participant completion take the form of 'terminal item completion;' (iii) Locally emergent structures like ' (...) class='Hi'>contrast' and 'list' as well as 'unprojected' features of turn construction often play an important role in enhancing the opportunity for completing another participant's utterance-in-progress. The article then discusses the implications of these findings for the investigation of the mutual bearing of grammar and social interaction. In particular, the discussion focuses on what we can learn from the practice of co-participant completion about how projection of turn-shapes is accomplished in Japanese conversation. (shrink)

Hilary Putnam’s influential analysis of the ‘division of linguistic labour’ has a striking application in the area of doctor–patient interaction: patients typically think of themselves as consumers of technical medical terms in the sense that they normally defer to health professionals’ explanations of meaning. It is at the same time well documented that patients tend to think they are entitled to understand lay health terms like ‘sickness’ and ‘illness’ in ways that do not necessarily correspond to health professionals’ understanding. (...) Drawing on recent philosophical theories of concept possession, the article argues that this disparity between medical and lay vocabulary implies that it is, in an important range of cases, easier for doctors to create a communicative platform of shared concepts by using and explaining special medical expressions than by using common lay expressions. This conclusion is contrasted with the view that doctors and patients typically understand each other when they use lay vocabulary. Obviously, use of expressions like ‘sickness’ or ‘illness’ does not necessarily lead to poor communication, but it is important that doctors have an awareness of how patients interpret such terms.
