Pretend play is generally considered to be a developmental landmark in Theory of Mind acquisition. The aim of the present paper is to offer a new account of the role of pretend play in Theory of Mind development. To this end I combine Hutto and Gallagher’s account of social cognition development with Matravers’ recent argument that the cognitive processes involved in engagement with narratives are neutral regarding fictionality. The key contribution of my account is an analysis of pretend play as (...) interaction with fictions. I argue that my account offers a better explanation of existing empirical data on the development of children’s pretend play and Theory of Mind than the competing theories from Leslie, Perner and Harris.

Background and purpose: The functional understanding and examination of competitive anxiety responses as temporal events that unfold as time-to-competition moves closer has emerged as a topical research area within the domains of sport psychology. However, little is known from an inclusive and interaction oriented perspective. Using the multidimensional anxiety theory as a framework, the present study examined the temporal patterning of competitive anxiety, focusing on the dimensions of intensity, direction, and frequency of intrusions in athletes across gender and skill (...) level. Methods: Elite and semi-elite Table Tennis athletes from the Ghanaian league (N= 90) completed a modified version of Competitive State Anxiety Inventory-2 (CSAI-2) with the inclusion of the directional and frequency of intrusion scales at three temporal phases (7 days, two days and 1 hour) prior to a competitive fixture. Results: MANOVA repeated measures with follow-up analyses revealed significant interactions for between-subjects factors on all anxiety dimensions (intensity, direction and frequency). Notably, elite (international) female athletes were less cognitively anxious, showed more facilitative interpretation towards somatic anxiety symptoms and experienced less frequency of somatic anxiety symptoms than their male counterparts. However, both elite groups displayed appreciable level of self-confidence. For time-to-event effects, both cognitive and somatic anxiety intensity fluctuated whereas self-confidence showed a steady rise as competition neared. Somatic anxiety debilitative interpretation slightly improved 1 hour before competition whereas cognitive anxiety frequencies also increased progressively during the entire preparatory phase. Conclusions: Findings suggest a more dynamic image of elite athletes’ pre-competitive anxiety responses than suggested by former studies, potentially influenced by cultural differences. The use of psychological skills interventions that require effective structure, content, and timing in a composite manner is suggested. (shrink)

In "Playing with Sound," Karen Collins examines video game sound from the player's perspective.

The combination of logic and game theory provides a fine-grained perspective on information and interaction dynamics, a Theory of Play. In this paper we lay down the main components of such a theory, drawing on recent advances in the logical dynamics of actions, preferences, and information. We then show how this fine-grained perspective has already shed new light on the long-term dynamics of information exchange, as well as on the much-discussed question of extensive game rationality.

My aim in this chapter is to use Marina Sbisà’s idea of interactional negotiation to consider what it is for conversing agents to follow illocutionary conventions or, as John L. Austin would put it, what it is for an illocutionary act to be done as conforming to a convention. The chapter is organized into two parts. In the first one, I use the Austinian notions of uptake and response as well as the Lewisian concept of accommodation to discuss a few (...) examples of force negotiation and develop a model of its underlying mechanisms. In the second part, I suggest that interactional negotiation plays a key role in the functioning of all language conventions—phatic, rhetic, illocutionary, etc.—construed along the Millikanian lines, i.e., as families or lineages of linguistic precedents. My contention is that the ideas I propose in this chapter are compatible with Sbisà’s theory of speech acts and can be regarded as its possible extension. (shrink)

Gupta has proposed a definition of strategic rationality cast in the framework of his revision theory of truth. His analysis, relative to a class of normal form games in which all players have a strict best reply to all other players’ strategy profiles, shows that game-theoretic concepts have revision-theoretic counterparts. We extend Gupta’s approach to deal with normal form games in which players’ may have weak best replies. We do so by adapting intuitions relative to Nash equilibrium refinements to the (...) revision-theoretic framework. We prove that there is a precise equivalence between trembling-hand perfect equilibria in two-player normal games and a revision-theoretic property. We then introduce lexicographic choice of action as a way to represent players’ expectations, which allows our analysis to reach full generality. Finally, we provide an example of the versatility of revision theory as applied to strategic interaction by formalizing a risk-and-compensation procedure of strategic choice in the revision-theoretic framework.

This article explores and compares cross-gender interactions of first and third graders in one child care center. Three prevalent forms of interaction are discussed: teasing, disputing, and playing. The author argues that these three forms of interaction are related to the use of space: Teasing often occurs when space is constricted, disputing is often the result of invaded space, and playing requires shared space and varying levels of cooperation. By focusing on the relationship between space and interaction, (...) important power asymmetries appear. Since boys are more likely to initiate invasions and more likely to determine the rules and terms of the play, they maintain a greater amount of power and control. (shrink)

The flow state – an experience of complete absorption in an activity – is linked with less self-referential processing and increased arousal. We used the heart-evoked potential, an index representing brain–heart interaction, as well as indices of peripheral physiology to assess the state of flow in individuals playing a video game. 22 gamers and 21 non-gamers played the video game Thumper for 25 min while their brain and cardiorespiratory signals were simultaneously recorded. The more participants were absorbed in the (...) game, the less they thought about time and the faster time passed subjectively. On the cortical level, the fronto-central HEP amplitude was significantly lower while playing the game compared to resting states before and after the game, reflecting less self-referential processing while playing. This HEP effect corresponded with lower activity during gameplay in brain regions contributing to interoceptive processing. The HEP amplitude predicted the level of absorption in the game. While the HEP amplitude was overall lower during the gaming session than during the resting states, within the gaming session the amplitude of HEP was positively associated with absorption. Since higher absorption was related to higher performance in the game, the higher HEP in more absorbed individuals reflects more efficient brain–heart interaction, which is necessary for efficient game play. On the physiological level, a higher level of flow was associated with increased overall sympathetic activity and less inhibited parasympathetic activity toward the end of the game. These results are building blocks for future neurophysiological assessments of flow. (shrink)

This paper addresses the concept of play concerning human formation, especially as manifested in the philosophies of Gadamer and Schiller. Gadamer depicted understanding as an organic motion that unfolds through seeing differences and characterized play as a flexible back-and-forth movement or interplay between possibilities and transformations. Schiller structured play as the playful impulse similarly as an interactive moving force that connects the two seemingly oppositional impulses of reason and sensation and lets the two affect the other dialogically. Both Gadamer (...) and Schiller suggest that play, as in essence an inter-play, orients us into seeing more possibilities of making a refreshing sense of our intellectual and perceptual abilities and thereby transfiguring our living being into richer and fuller meaningfulness.

Using anthropological theory, this paper examines human–android interactions (HAI) as an emerging aspect of android science. These interactions are described in terms of adaptive learning (which is largely subconscious). This article is based on the observations reported and supplementary data from two studies that took place in Japan with a teleoperated android robot called Telenoid in the socialization of school children and older adults. We argue that interacting with androids brings about a special context, an interval, and a space/time for (...) reflection and imagination that was not there before. During the interaction something happens. There is adaptive learning and as a result, both children and older adults accepted Telenoid, and the children and older adults accepted each other. Using frames of play and ritual, we make sense and ‘capture’ moments of adaptive learning, and the feedback that elicits a social response from all study participants that results in self-efficacy and socialization. While “ritual” refers to the application of what has been learned and “play” means that there are no obvious consequences of what has been learned. This analysis illuminates new understanding about the uncanny valley, cultural robotics and the therapeutic potential of HAI. This has implications for the acceptance of androids in ‘socialized roles’ and gives us insight into the subconscious adaptive learning processes that must take place within humans to accept androids into our society. This approach aims to provides a clearer conceptual basis and vocabulary for further research of android and humanoid development. (shrink)

Simulations, in which healthcare professionals are observed in dialogue with role-played patients, are widely used for assessing professional skills. Medical education research suggests simulations should be as authentic as possible, but there remains a lack of linguistic research into how far such settings authentically reproduce talk. This article presents an analysis of a corpus of general practice simulations in the United Kingdom, comparing this to a dataset of real-life general practitioner consultations. Combining corpus linguistic and conversation analytic methodologies, key interactional (...) features of the simulations are identified, particularly those associated with successful/unsuccessful performance in terms of the examiner’s grading. The corpus analysis identifies various forms of the phrase ‘tell me more about’ to occur significantly more frequently in the simulations compared to real GP consultations, typically in the opening sequences and most frequently in successful cases. It falls to a conversation analysis of the data, examining this phrase within the interactional context of these opening sequences, to better understand the actions it performs. Successful candidates in the simulations are found to perform a consistent sequential pattern, often incorporating this phrase. Although simulated, these interactions have real professional consequences for those being assessed. Linguistic findings about what constitutes successful interaction or differences to real-life practice therefore have important implications for professional education and assessment. (shrink)

In ethical reflections on new technologies, a specific type of argument often pops up, which criticizes scientists for “playing God” with these new technological possibilities. The first part of this article is an examination of how these arguments have been interpreted in the literature. Subsequently, this article aims to reinterpret these arguments as symbolic arguments: they are grounded not so much in a set of ontological or empirical claims, but concern symbolic classificatory schemes that ground our value judgments in the (...) first place. Invoking symbolic arguments thus refers to how certain new technologies risk undermining our fundamental symbolic distinctions by which we organize and evaluate our interactions with the world and in society. Such symbolic distinctions, moreover, tend to be resilient against logical argumentation, mainly because they themselves form the basis on which we argue in the cultural and ethical sphere in the first place. Therefore, effective strategies to evaluate and counter these arguments require another approach, showing that these technologies either do not challenge these classifications or, if they do, how they can be accompanied by the proper actions to integrate these technologies into our society.

In the context of interspecies play involving humans, we find limitations when it comes to understanding most species. One reason for this may be the fact that we tend to anthropomorphize the other to be able to empathize with it. In light of this, how can we infer communication signs of other species so we are able to connect with the nonhuman world? We look for answers to this question by adopting a phenomenological approach that allows us to decentre from (...) the anthropocentric perspective. We highlight animal studies, especially those that extend to them the notion of play, and the studies on interspecies playful interaction conducted in the context of animal‐computer interaction. In addition, we propose considering empathy as an interspecies dialogical bridge with nonhumans. Finally, we argue about an expansion of the field of interaction design as an approach to the connection with the nonhuman world. (shrink)

An important shift is taking place in social cognition research, away from a focus on the individual mind and toward embodied and participatory aspects of social understanding. Empirical results already imply that social cognition is not reducible to the workings of individual cognitive mechanisms. To galvanize this interactive turn, we provide an operational definition of social interaction and distinguish the different explanatory roles – contextual, enabling and constitutive – it can play in social cognition. We show that interactive processes (...) are more than a context for social cognition: they can complement and even replace individual mechanisms. This new explanatory power of social interaction can push the field forward by expanding the possibilities of scientific explanation beyond the individual. (shrink)

From the grotesque pavilions hidden in sixteenth century Italian gardens to the temporary structures in public space in the 70s and recent digitally augmented environments, architectures of play have long been designed to engage explorative experiences. The uncertainty of play allows us to probe new behaviors, to poke into the boundaries of subjectivity and to interact with people, things and systems in unexpected and unfamiliar ways. In this essay, we explore how an interactive system, situated in public space, may foster (...) explorative activities and enable the transformative power of play. Through the analysis of several computer-augmented architectures, we examine what interactive qualities might enhance the transformative power of play. Beginning with the Fun Palace, an early attempt to use cybernetics in order to encourage visitors to experiment with their habits, we move to contemporary projects including some of the author’s own work. The latter takes the advantage of existing public locations in order to insert exploratory play into everyday life. Through analysis of these projects, we discuss whether such environments raise our responsibility toward others within our surroundings; whether they enable us to transform our own established behaviors; and whether they empower us to reclaim public space.

Knowledge of the context and development of playful expressions in chimpanzees is limited because research has tended to focus on social play, on older subjects, and on the communicative signaling function of expressions. Here we explore the rate of playful facial and body expressions in solitary and social play, changes from 12- to 15-months of age, and the extent to which social partners match expressions, which may illuminate a route through which context influences expression. Naturalistic observations of seven (...) chimpanzee infants ( Pan troglodytes ) were conducted at Chester Zoo, UK ( n = 4), and Primate Research Institute, Japan ( n = 3), and at two ages, 12 months and 15 months. No group or age differences were found in the rate of infant playful expressions. However, modalities of playful expression varied with type of play: in social play, the rate of play faces was high, whereas in solitary play, the rate of body expressions was high. Among the most frequent types of play, mild contact social play had the highest rates of play faces and multi-modal expressions (often play faces with hitting). Social partners matched both infant play faces and infant body expressions, but play faces were matched at a significantly higher rate that increased with age. Matched expression rates were highest when playing with peers despite infant expressiveness being highest when playing with older chimpanzees. Given that playful expressions emerge early in life and continue to occur in solitary contexts through the second year of life, we suggest that the play face and certain body behaviors are emotional expressions of joy, and that such expressions develop additional social functions through interactions with peers and older social partners.

Ken Binmore's previous game theory textbook, Fun and Games, carved out a significant niche in the advanced undergraduate market; it was intellectually serious and more up-to-date than its competitors, but also accessibly written. Its central thesis was that game theory allows us to understand many kinds of interactions between people, a point that Binmore amply demonstrated through a rich range of examples and applications. This replacement for the now out-of-date 1991 textbook retains the entertaining examples, but changes the organization to (...) match how game theory courses are actually taught, making Playing for Real a more versatile text that almost all possible course designs will find easier to use, with less jumping about than before. In addition, the problem sections, already used as a reference by many teachers, have become even more clever and varied, without becoming too technical. Playing for Real will sell into advanced undergraduate courses in game theory, primarily those in economics, but also courses in the social sciences, and serve as a reference for economists.

Textbooks have played the leading role in academic education for centuries and their form has evolved, adapting to the needs of students, teachers and technological possibilities. Advances in technology have caused educators to look for new sources of knowledge development, which students could use inside and outside the classroom. Today’s sophisticated learning tools range from virtual environments to interactive multimedia resources, which can be called e-textbooks. Different types of new educational materials that go beyond printed books are now used to (...) support the academic curriculum, with the most interesting ones exemplified in this article to show their value in medical and life sciences education. Certain interesting attempts by Polish publishers at applying technology to support both self-paced and tutor-paced student learning in the medical profession and related areas are presented. The data was collected through a review of literature, discussions with e-learning specialists and medical students, as well as an analysis of examples of good practices. The article also discusses the results of a countrywide survey on the use of e-textbooks to enhance medical education. The research investigates the targeted academic staff’s attitudes towards the use of e-textbooks, the limitations of their implementation, and the character of e-resources currently used by Polish higher education medical institutions.

Recent philosophy of science has seen a number of attempts to understand scientific models by looking to theories of fiction. In previous work, I have offered an account of models that draws on Kendall Walton’s ‘make-believe’ theory of art. According to this account, models function as ‘props’ in games of make-believe, like children’s dolls or toy trucks. In this paper, I assess the make-believe view through an empirical study of molecular models. I suggest that the view gains support when we (...) look at the way that these models are used and the attitude that users take towards them. Users’ interaction with molecular models suggests that they do imagine the models to be molecules, in much the same way that children imagine a doll to be a baby. Furthermore, I argue, users of molecular models imagine themselves viewing and manipulating molecules, just as children playing with a doll might imagine themselves looking at a baby or feeding it. Recognising this ‘participation’ in modelling, I suggest, points towards a new account of how models are used to learn about the world, and helps us to understand the value that scientists sometimes place on three-dimensional, physical models over other forms of representation.

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

This paper explores how preschools can be purposefully designed to aid cultural learning through guided play practices. In recent literature, there has been a renowned interest in the role of the exogenous environment in psychological processes, including learning. The idea that the design of preschools can meaningfully be seen as cultural niche construction and that guided play practices in these environments can aid the preparation for cultural action, is promoted, and a theoretical framework is presented. The empirical data draw from (...) a synthesis from three ethnographic research sites in multilingual communities, and data are used to explore how cultural affordances are used in designed environments as part of guided play practices. The results indicate how niche construction of affordances aid cultural learning and is achieved through both direct guided play interaction between teachers and children, but also in the way of the indirect design of environments that is incorporated in children’s peer play. It is discussed what this means for play research as well as for guided play practices that aim to promote cultural learning. (shrink)

Recent research shows – somewhat astonishingly – that people are willing to ascribe moral blame to AI-driven systems when they cause harm [1]–[4]. In this paper, we explore the moral- psychological underpinnings of these findings. Our hypothesis was that the reason why people ascribe moral blame to AI systems is that they consider them capable of entertaining inculpating mental states (what is called mens rea in the law). To explore this hypothesis, we created a scenario in which an AI system (...) runs a risk of poisoning people by using a novel type of fertilizer. Manipulating the computational (or quasi-cognitive) abilities of the AI system in a between-subjects design, we tested whether people’s willingness to ascribe knowledge of a substantial risk of harm (i.e., recklessness) and blame to the AI system. Furthermore, we investigated whether the ascription of recklessness and blame to the AI system would influence the perceived blameworthiness of the system’s user (or owner). In an experiment with 347 participants, we found (i) that people are willing to ascribe blame to AI systems in contexts of recklessness, (ii) that blame ascriptions depend strongly on the willingness to attribute recklessness and (iii) that the latter, in turn, depends on the perceived “cognitive” capacities of the system. Furthermore, our results suggest (iv) that the higher the computational sophistication of the AI system, the more blame is shifted from the human user to the AI system. (shrink)

The purpose of this article is to present a phenomenological description of how athletes in specific risk sports explore human interaction with natural elements. Skydivers play with, and surf on, the encountering air while falling towards the ground. Kayakers play on the waves and with the stoppers and currents in the rivers. Climbers are ballerinas of the vertical, using cracks and holds in the cliffs to pull upwards against gravity forces. The theoretical background for the description is found in (...) the phenomenology of Heidegger and Merleau-Ponty. The phenomenology of Husserl focused on the theoretical intentionality of the transcendental ego. With Heidegger the human being's concrete and practical interaction with the environing world moved to the foreground. Heidegger's analyses of ?equipmentality? also throw important light on equipmentality in sports and how we deal with tools and equipment in sports. However, in Heidegger's analyses the body resides in the background both as subject and object. The importance of the active body-subject is well documented in the work of Merleau-Ponty, and also Todes. The human being is a bodily ?being-in-the-world? and the body is the active medium through which the world is grasped. The body is however also situated and aligned with the fundamental dimensions of the world, with vertical gravity and with horizontal action space. In this article I show in a concrete way how in some sports we use fundamental characteristics of the environing world in a mode of playfulness. In these sports human beings play in an extreme way with fundamental elements of nature. The article thus puts phenomenology to a test. It should be able to move from general characteristics to specific features of our bodily human involvement with the environing world. (shrink)

Our article aims to show, on the one hand, the preeminence of the interactive paradigm as a determining element in the process of constitution of logical meaning and, on the other hand, to examine the contents of the linguistic expressions of pragmatic semantics. To do this, we expose three major figures of the logic of mathematical obedience in particular those of Gottfreid Leibniz, George Boole and Gottlob Frege. If this approach to mathematical logic has seen meritorious progress, it should be (...) pointed out that it does not favor the emphasis on epistemic and interactive aspects in the notions of logical consequences and inference. Our contribution is therefore to demonstrate that these weaknesses can be solved with the revolutionary approach of Robert Brandom based on the framework that promotes the interactive game of supply and demand of reasons. This analysis leads to the idea that interactive play is the basis of contemporary logical approaches. (shrink)

The aim of this article is to argue that what is distinctive about aesthetic experiences has to do with what we do -- not with our perception or evaluation, but with our action and, more precisely, with our interaction with whatever we are aesthetically engaging with. This view goes against the mainstream inasmuch as aesthetic engagement is widely held to be special precisely because it is detached from the sphere of the practical. I argue that taking the interactive nature (...) of aesthetic experiences seriously can help us to understand some of the most important features of aesthetic experiences and the role they play in our life: their normativity, their crucial role in the ways in which the aesthetic domain looms large in our self-image and in the social dimension of aesthetic engagement.

Interactions of fathers and their children with autism1 The aim of the present study was to compare the activity of fathers and their children with autism with those of children with Down syndrome, and normally developing children during the father-child interaction. Participants were 14 children with autism and their fathers, 15 children with Down syndrome and their fathers, and 16 normally developing children and their fathers. The age of subjects was between 3.0 and 6.0 years old. The study consisted (...) of one 15-minute free-play session in the father-child diad, taking place in the experiment room. Differences between the groups of fathers were found in terms of three variables under analysis: frequency of looking at the child, physical contact with the child and suggesting play. Children with autism brought objects to their fathers or pointed out objects and directed their fathers' attention by vocalising less frequently than children with Down syndrome and normally developing children. Moreover, children with autism exhibited the fewest vocalisations combined with looking at the father and exhibited many more behaviours involving running and moving about the room than normally developing children. Self-stimulating behaviours were the most frequent in children with autism, with no differences in that respect found between children with Down syndrome and normally developing children. The analysis of fathers' behaviour demonstrates that fathers of children with developmental disorders focus on observing their children and attempt to keep close contact with them to a larger extent than fathers of normally developing children. The pattern of differences in the activity of fathers of children with autism and children with Down syndrome does not paint a clear picture. In general, fathers from both groups actively sought to maintain contact with their children. Differences in the activity during play between children with autism and the other subjects in the study are consistent with the clinical features of autism. (shrink)

An interaction between the ways morality and society develop in the face of the challenges they are exposed to seems consistent with empirical evidence. However, within this frame man's instinct of self preservation and his individualism seem to play an important part. The former by its influence on the evolution of what I refer to as 'our social morality'. The latter by finding its expression in conservative and radical ideologies whose political confrontation appears to give rise to an evolutionary (...) develop ment. The paper draws attention to the fact that in the face of contemporary challenges the evolutionary development of our morals may determine whether the corresponding evolutionary development of our societies will approach the patterns of those of insects, or whether our highly developed individual istic traits will result in new moral trends creating a society which is better suited to the present characteristics of humankind. It is also argued that the present growth of international organizations for cooperation and peaceful co-existence should make it possible to build a society worthy of the human race, but that it could be done only if we are able to develop a sufficient sense of responsibility to deliberately keep over-consumption and human population within a natural balance.

This study investigates interpersonal processes underlying dialog by comparing two approaches, interactive alignment and interpersonal synergy, and assesses how they predict collective performance in a joint task. While the interactive alignment approach highlights imitative patterns between interlocutors, the synergy approach points to structural organization at the level of the interaction—such as complementary patterns straddling speech turns and interlocutors. We develop a general, quantitative method to assess lexical, prosodic, and speech/pause patterns related to the two approaches and their impact on (...) collective performance in a corpus of task-oriented conversations. The results show statistical presence of patterns relevant for both approaches. However, synergetic aspects of dialog provide the best statistical predictors of collective performance and adding aspects of the alignment approach does not improve the model. This suggests that structural organization at the level of the interaction plays a crucial role in task-oriented conversations, possibly constraining and integrating processes related to alignment.

In this book, Ted Peters explores the fallacies of the "gene myth" and presents a resounding array of arguments against this kind of all-encompassing genetic determinism. On the scientific side, he correctly points out that genetic influences on behavior are in most instances relatively modest. Does anyone deny that identical twins are still able to practice individual free will? After dispatching some of the sweepingly deterministic conclusions of the "science" of evolutionary psychology with a particularly effective set of rebuttals, Peters (...) arrives at the conclusion that the nature of humanness is an interaction of three things- not one, not two, but three: genetics, environment, and free will. Neglecting any one of these three leads down a path of fuzzy thinking and dangerous consequences. (shrink)

Lysosomal positioning is an important factor in regulating cellular responses, including autophagy. Because proteins encoded by disease‐responsible genes are involved in lysosomal trafficking, proper intracellular lysosomal trafficking is thought to be essential for cellular homeostasis. In the past few years, the mechanisms of lysosomal trafficking have been elucidated with a focus on adapter proteins linking motor proteins to lysosomes. Here, we outline recent findings on the mechanisms of lysosomal trafficking by focusing on adapter protein c‐Jun NH2‐terminal kinase‐interacting protein (JIP) 4, (...) which plays a central role in this process, and other JIP4 functions and JIP family proteins. Additionally, we discuss neuronal diseases associated with aberrance in the JIP family protein. Accumulating evidence suggests that chemical manipulation of lysosomal positioning may be a therapeutic approach for these neuronal diseases. (shrink)

The burgeoning field of studies in expertise and experience is a useful theoretical approach to complex problems. In light of SEE, examination of the controversial and well known case study of dolphin bycatch in the US tuna fishery, reveals that effective problem-solving was hindered by institutional tensions in respect of decision-making authority and difficulties with the integration of different expertises. Comparing the profiles of four individuals, who played distinct roles in the problem-solving process, I show that to address a complex (...) problem, a suite of contributory expertises—rarely found in one individual—may be required; formal credentials are not a reliable indicator of who possesses these necessary expertises; interactional expertise and interactive ability are useful tools in combining the contributory expertises of others to yield a desirable collective outcome; and the concepts of contributory expertise and no expertise are useful tools for understanding the actual contribution of various parties to the problem-solving process.Keywords: Expertise and experience; Bycatch; Tuna-dolphin; Invention; Conservation technology; Interactional expertise.

Participatory Technology Assessment initiatives have usually been analyzed as if they existed in a social and political vacuum. This article analyzes the linkages that occur, in both directions, between the microcosm set up by a pTA exercise and the real world outside. This dual-dynamics perspective leads to a new way of understanding the function and significance of pTA initiatives. Rather than viewing them as a means to create the ideal conditions for real public debate, they are viewed here as an (...) additional public arena in which sociotechnical controversies are played out. This perspective is developed from the analysis of an interactive technology assessment exercise conducted by the French National Institute for Agricultural Research, on the topic of genetically modified vines.

This article addresses keep-fit culture not as a collection of commercial images or as the product of broader cultural values, but as a set of situated body practices, that is practices taking place within specific institutions where these images and values are reinterpreted in locally prescribed ways and, to some extent, filtered. Relying on fieldwork, fitness gyms are revealed to be experienced as places with their own rules, pleasures and identity games. The ideal of the fit body is shown to (...) be filtered from its wider, typically gender- and class-specific charges, transformed into a pure instrument of training, a machine which does not bear resemblance to the organic body of the changing rooms, an objectified utility which is beyond any social role specification. Social roles and their body requirements are both important for individual clients' structural chances to join the gym and locally neutralized or reduced to tension-release mechanisms. Similarly, the cultural ideals of a fit and toned body contribute to the legitimation of the gym; yet the actual capacity to train is less the result of the direct grip of culture, than the outcome of clients' adjustment to playing a particular game of involvement with and detachment from the mechanistic and abstract exercise body. Body definitions are not simply imposed on clients, but continuously negotiated and transformed. (shrink)

It can hardly be denied that play is an important tool for the development and socialisation of children. In this article we argue that, through dramaturgical play in combination with pedagogical tools such as the Community of Inquiry (CoI), in the tradition of Philosophy for Children (P4C), students can creatively think, reflect and be more aware of the impact their gestures (Schmid 2000b) have on others. One of the most fundamental aspects of the embodied human life is human interaction (...) that is based on expressions, what Schmid calls gestures. Through self-reflection, one’s set of gestures can be developed into a deliberate ‘life-performance’; a conscious, selected and coherent work of art (Schmid, 2000b, p. 332). Drawing on Nietzsche’s idea of living artistically, we explore how Schmid’s philosophy of the art of living, P4C and the liberal arts, with a focus on drama education, can work together to develop (self-) reflective, reasonable citizens who are able to develop their own art of living while respecting and supporting the development of the good and beautiful life of others.
