For a robot to cohabit with people, it should be able to learn people’s nonverbal social behavior from experience. In this paper, we propose a novel machine learning method for recognizing gestures used in interaction and communication. Our method enables robots to learn gestures incrementally during human–robot interaction in an unsupervised manner. It allows the user to leave the number and types of gestures undefined prior to the learning. The proposed method (HB-SOINN) is based on a self-organizing incremental neural network (...) and the hidden Markov model. We have added an interactive learning mechanism to HB-SOINN to prevent a single cluster from running into a failure as a result of polysemy of being assigned more than one meaning. For example, a sentence: “Keep on going left slowly” has three meanings such as, “Keep on (1)”, “going left (2)”, “slowly (3)”. We experimentally tested the clustering performance of the proposed method against data obtained from measuring gestures using a motion capture device. The results show that the classification performance of HB-SOINN exceeds that of conventional clustering approaches. In addition, we have found that the interactive learning function improves the learning performance of HB-SOINN. (shrink)

In his writings Philosophical Remarks, the Austrian-British Philosopher Ludwig Wittgenstein draws an octahedron with the words of pure colours such as “white”, “red” and “blue” at the corners and argues: “The colour octahedron is grammar, since it says that you can speak of a reddish blue but not of a reddish green, etc”. He uses the word “grammar” in such a specific way that the grammar or grammatical rules describe the meanings of words/expressions, in other words, how we use them (...) in our language. Accordingly, the colour octahedron can also be taken to represent grammatical rules about how we apply words of colour, e.g., that we can call a certain colour “reddish-blue”, but not “reddish-green”. In a different context, the Japanese philosopher Shūzō Kuki explores in his work The Structure of Iki what the Japanese word “iki” means. This word is often translated as “chic” or “stylistic” in English, but Kuki holds that it is an aesthetic Japanese concept that cannot be translated one-to-one, instead encompassing three aspects: “coquetry”, “pride and honour” and “resignation”. To explain the meanings of the word “iki” and other related words all of which Kuki calls “tastes”, he introduces a rectangular prism as a geometrical representation similar to Wittgenstein’s colour octahedron. In this paper, I argue that the rectangular prism does not solely explain how the modes of Japanese tastes are related to each other, but also has a grammatical character. On this score, I suggest that one can regard this rectangular prism as a description of the grammatical rules of the Japanese language. By appeal to the arguments of both philosophers and in comparison with them, I will not only clarify what they claim by geometrical representations but also examine what role this kind of representation plays as an explanation of grammar in general. Keywords: grammar, colour octahedron, rectangular prism, Shūzō Kuki, Wittgenstein. (shrink)

Recently Lafont [6] showed the finite model property for the multiplicative additive fragment of linear logic (MALL) and for affine logic (LLW), i.e., linear logic with weakening. In this paper, we shall prove the finite model property for intuitionistic versions of those, i.e. intuitionistic MALL (which we call IMALL), and intuitionistic LLW (which we call ILLW). In addition, we shall show the finite model property for contractive linear logic (LLC), i.e., linear logic with contraction, and for its intuitionistic version (ILLC). (...) The finite model property for related substructural logics also follow by our method. In particular, we shall show that the property holds for all of FL and GL - -systems except FL c and GL - c of Ono [11], that will settle the open problems stated in Ono [12]. (shrink)

Preliminary evidence suggests that daydreaming about other people has adaptive value in daily social lives. To address this possibility, we examined whether daydreaming plays a role in maintaining close, stable relationships using a 1-year prospective longitudinal study. We found that individuals’ propensity to daydream about their marital partner is separate to general daydreaming. In contrast to general daydreaming, which was associated with lower subsequent relationship investment size in the marital partner, partner-related social daydreaming led to a greater subsequent investment size. (...) Additionally, attachment styles moderated these effects. The effect of daydreaming regarding investment size was found only in securely attached individuals. This research advances the emerging field of social daydreaming and highlights self-generated thought as a critical tool that can help people navigate the complex social world. (shrink)

Narrative views of the self argue that we constitute our self in self-narratives. Embodied views hold that our self is shaped through embodied experiences. In that case, what is the relation between embodiment and narrativity in the process of self-constitution? The question demands a clear definition of embodiment, but existing studies remains unclear on this point (section 2). We offer a correction to this situation by drawing on Merleau-Ponty’s analysis of the body that highlights its habituality. On this account, the (...) body has an inherent tendency to cultivate an organization of habits through its history of engagement with the world (section 3). Next, we explore its role in narrative self-constitution by distinguishing between two aspects of the narrative self, the narrated I and the narrating I (section 4). We argue on phenomenological grounds that self-narratives are informed by bodily perspectives in both respects. Furthermore, a focus on the habituality of the body allows for a better explanation of self-constitution than those based on implicit self-narratives (section 5). For these phenomenological and theoretical reasons, we conclude that narrative self-constitution is an embodied and embedded practice (section 6). (shrink)

We present some ideas on logical process descriptions, using relations from the DIO (Drug Interaction Ontology) as examples and explaining how these relations can be naturally decomposed in terms of more basic structured logical process descriptions using terms from linear logic. In our view, the process descriptions are able to clarify the usual relational descriptions of DIO. In particular, we discuss the use of logical process descriptions in proving linear logical theorems. Among the types of reasoning supported by DIO one (...) can distinguish both (1) basic reasoning about general structures in reality and (2) the domain-specific reasoning of experts. We here propose a clarification of this important distinction between (realist) reasoning on the basis of an ontology and rule-based inferences on the basis of an expert’s view. (shrink)

Following on from Shaun Gallagher's influential 2005 book How the Body Shapes the Mind, this volume brings together leading experts from the fields of philosophy, neuroscience, psychology, and psychiatry in a productive dialogue, exploring key questions and debates about the relationship between body schema and body image.

To investigate the cognitive processes underlying creative inspiration, we tested the extent to which viewing or copying prior examples impacted creative output in art. In Experiment 1, undergraduates made drawings under three conditions: copying an artist's drawing, then producing an original drawing; producing an original drawing without having seen another's work; and copying another artist's work, then reproducing that artist's style independently. We discovered that through copying unfamiliar abstract drawings, participants were able to produce creative drawings qualitatively different from the (...) model drawings. Process analyses suggested that participants' cognitive constraints became relaxed, and new perspectives were formed from copying another's artwork. Experiment 2 showed that exposure to styles of artwork considered unfamiliar facilitated creativity in drawing, while styles considered familiar did not do so. Experiment 3 showed that both copying and thoroughly viewing artwork executed using an unfamiliar style facilitated creativity in drawing, whereas merely thinking about alternative styles of artistic representation did not do so. These experiments revealed that deep encounters with unfamiliar artworks—whether through copying or prolonged observation—change people's cognitive representations of the act of drawing to produce novel artwork.

We introduce subsystems WLJ and SI of the intuitionistic propositional logic LJ, by weakening the intuitionistic implication. These systems are justifiable by purely constructive semantics. Then the intuitionistic implication with full strength is definable in the second order versions of these systems. We give a relationship between SI and a weak modal system WM. In Appendix the Kripke-type model theory for WM is given.

Body image and body schema refer to two different yet closely related systems. Whereas BI can be defined as a system of perceptions, attitudes, and beliefs pertaining to one's own body, BS is a system of sensory-motor capacities that functions without awareness or the necessity of perceptual monitoring. Studies have demonstrated that applying the concepts of BI and BS enables us to conceptualize complex pathological phenomena such as anorexia, schizophrenia, and depersonalization. Likewise, it has further been argued that these concepts (...) play a crucial role in our ability to grasp our bodily experiences in the socio-cultural world according to various factors, such as gender, social class, and ethnicity. Referring to the insights of Frantz Fanon, the author of Black Skin, White Masks, this paper suggests that under certain conditions the BI can take over and reshape the BS. Based on an examination of Fanon’s writings, the paper suggests that not only the BI can truly remold the BS but that the gaze of the other can directly influence the BI. (shrink)

It is well known that the modal logic S5 can be embedded in the classical predicate logic by interpreting the modal operator in terms of a quantifier. Wajsberg [10] proved this fact in a syntactic way. Mints [7] extended this result to the quantified version of S5; using a purely proof-theoretic method he showed that the quantified S5 corresponds to the classical predicate logic with one-sorted variable. In this paper we extend Mints' result to the basic modal logic S4; we (...) investigate the correspondence between the quantified versions of S4 (with and without the Barcan formula) and the classical predicate logic (with one-sorted variable). We present a purely proof-theoretic proof-transformation method, reducing an LK-proof of an interpreted formula to a modal proof. (shrink)

The involvement of nitric oxide in cerebellar long-term depression is supported by the observation that nitric oxide is released by climbing fiber stimulation and by pharmacological tool usage. Two forms of long-term depression should be distinguished by their physiological relevance. [CRÉPEL et al.; LINDEN; VINCENT].

We treat a class of multi-person bargaining mechanisms based on games in coalitional form. For this class of games we identify properties of non-cooperative solution concepts, which are necessary and sufficient for the equilibrium outcomes to coincide with the core of the underlying coalitional form game. We view this result as a non-cooperative axiomatization of the core. In contrast to most of the literature on multi-person bargaining we avoid a precise specification of the rules of the game. Alternatively, we impose (...) properties of such games, which give rise to a large class of mechanisms, all of which are relevant for our axiomatization. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.4 (2003) 73-84 [Access article in PDF] Music-Picture:One Form of Synthetic Art Education"Music-picture (a picture drawn through musical perception)" has been widely accepted by art educators in Japan. The purpose of this essay is to propose the making of music-pictures as art education and to put it on afirm theoretical base. I first investigate three gestalt rules: adjacency, continuance, and resemblance, all of which (...) are applicable to the senses of both seeing and hearing. Next I present research on color hearing as one version ofsynaesthesia, which is the comprehensive faculty that binds the five senses in various ways. The well-organized music-picture program by Kaoru Sasaki 1 is introduced as an example. 2 The synthetic art-educational value of music-picture will become clearer through these examinations. The Interrelations between Visual Arts and Music It is exciting that the visual arts meet music in an art class, even if these subjects are entirely different in regard to media, expressive form, the category of perception, and mastery of techniques. Put simply, Picasso's works are visible, whereas Stravinsky's pieces are invisible. Nevertheless, both powerfully convey imaginative and often narrative messages. Relying on intuition alone, I firmly believe both are interchangeable.My research on common methods of organizing both recorded music and painting was my first observation of the mutual relationship between music and visual arts. 3 But what I considered then would not be applied to art class directly because the research was based on my practical experience. It did not have any educational goals. Now I recognize that instructive approaches are necessary to lay the foundation for art classes dealing with interaction between two distinct modalities.In Japan, the Ministry of Education and Science provides the government curriculum guidelines nearly every ten years. It contains descriptions on two subjects: The visual arts and music taught in these classes are at an elementary school level and a junior high school level, both located within a compulsory education system. The new version has been in force since April 2002 (the new school term starts in April in Japan). Objectives in the two educational fields are similar and ideas of what art and music education ought to be are almost the same. The aim common to both in the government curriculum guidelines: "Through expression and appreciation, we [End Page 73] cultivate students' sentiments" invites the linking of music and the visual arts across the curriculum.Many art educators in Japan are interested in this sort of idea and have actually put it into practice. 4 They are engaged in interrelating or even unifying music and the visual arts. Additionally I know other teachers who have designed and proposed many ideas toward this crossover. Listed below are general ideas that seek to combine visual arts with music in an art class.1) Music-picture: to make a pictorial description of impressions received from music.2) Sound map: to make a map of sounds heard at a given location. Each sound is visualized by simple marks like - - -, <<<, ~~~, ooo, and xxx.3) Graphic notation: to write a score which directs the details, whole form, and progression of music by graphics instead of staff notation. Using onomatopoeias or instructions by words are common. It can be improvised, based on intuitively translating visual impacts into sounds.4) Sound toy: to make an original musical instrument of familiar easil obtained materials. For instance, a corrugated cardboard ukulele whose strings are rubber bands, a pair of maracas made of empty cans and soybeans, and so forth.5) Sound sculpture: to make sculpture producing interesting sounds (sometimes noises like creak or clatter). Extensive genres: wood sculpture, metal construction, assemblage (junk arts), kinetic arts, and so on.6) Sound installation: to make a place where participants experience sounds generated by objects or equipment.7) Multimedia: in the broad sense, to mix visuals with music; noises like jingle, tap, and bang! in daily life, or natural environmental sounds like a pit-a-pat of falling rain, a whisper of leaves, or...

In the performing arts, such as music and dance performances, people actively interact with each other and show their exciting performances. Some studies have proposed that this interaction is a social origin of the performing arts. Some have further investigated this phenomenon based on the synchronization and coordination theory. Though the majority of these studies have focused on the collaborative context, several genres of the performing arts, such as jazz sessions and breakdance battles, have a competitive context. Several studies have (...) suggested that, in this competitive context, performers actively interact with each other and construct some correspondence. Moreover, a few recent studies focusing on competitive conversations, such as debates, have shown that, compared to people's interactions in collaborative conversations, people in competitive contexts frequently coordinate their behaviors in complicated ways. However, the interaction and coordination among performers in these competitive contexts have not been sufficiently investigated. Therefore, we investigated the coordination of expert breakdancers in battle scenes and measured their rhythmic movements using a motion capture system. We calculated the relative phase of the rhythmic movements between two dancers to investigate their coordination. The results showed that the dancers' rhythmic movements tended to synchronize in an anti-phase fashion, which means that there were similarities as well as differences between the two dancers' rhythmic movements. Furthermore, this pattern of coordination changed dynamically as time elapsed, from an in-phase synchronization or leader-follower relationships to an anti-phase synchronization and then leader-follower relationships.

Hobbes's unusual religious views in his classical work, Leviathan, are often seen as a product of his attempt to reconcile Christianity with his philosophical materialism. Yet given Hobbes's materialistic view in his earlier works too, this explanatory framework alone is not sufficient for grasping distinctive features of Leviathan. This article remedies this lacuna by paying close attention to an understudied aspect of the development of Hobbes's religious theory from The Elements of Law to Leviathan: his treatment of the supernatural and, (...) particularly, of matters of faith known by supernatural revelation as opposed to natural reason. I argue that over time Hobbes developed an epistemological analysis of supernatural revelation and refined his argument about the sense in which matters of faith are supernatural and about the extent to which they are found in the Bible. It was not materialism per se but the more sophisticated analysis of the supernatural in Leviathan that enabled Hobbes to admit the sphere of the supernatural to a much smaller extent than in De Cive and to discuss in detail what he sees as a matter of faith and beyond the scope of philosophy in De Cive.
