To let humanoid robots behave socially adequate in a future society, we started to explore laughter as an important para-verbal signal known to influence relationships among humans rather easily. We investigated how the naturalness of various types of laughter in combination with different humanoid robots was judged, first, within a situational context that is suitable for laughter and, second, without describing the situational context. Given the variety of human laughter, do people prefer a certain style for a robot’s laughter? And (...) if yes, how does a robot’s outer appearance affect this preference, if at all? Is this preference independent of the observer’s cultural background? Those participants, who took part in two separate online surveys and were told that the robots would laugh in response to a joke, preferred one type of laughter regardless of the robot type. This result is contrasted by a detailed analysis of two more surveys, which took place during presentations at a Japanese and a German high school, respectively. From the results of these two surveys, interesting intercultural differences in the perceived naturalness of our laughing humanoids can be derived and challenging questions arise that are to be addressed in future research.

Grodzinsky's general approach to the neuroscience of language is interesting, but the evidence currently available has problems with pragmatic infelicity in experiments involving Japanese scrambling and the interpretation of experimental results on Japanese indirect passives. I will suggest a more direct way of testing the Trace-Deletion Hypothesis (TDH).

The famous Japanese novelist offers his personal interpretation of a classic work on samurai ethics, everyday life, and spiritual salvation.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 59-69 [Access article in PDF] Buddhist Views on Ritual Pactice Protestant Character of Modern Buddhist Movements Yukio MatsudoUniversity of HeidelbergWhat is the relationship between ritual and ethical activities in Nichiren Buddhism, as practiced in the Soka Gakkai (SG)? SG is a lay Buddhist organization which is, as such, involved extensively in secular affairs, specifically in the field of educational, cultural, social, and peace-promoting programs. (...) The question is, therefore, not at all whether there is a connection of religious practice and ethical activities. Rather it begs an explanation regarding its ideological background. In this respect a further reflection on a metareflection level would be useful to clarify the "modern" character of SG, which may be discussed in relation to Christian Protestantism since it has been regarded as a spiritual background for the formation of modern ethos such as individualism, egalitarianism, and social engagement. Thus, I will depict the fundamental feature of Nichiren Buddhism as "reformative Buddhism," which makes the practice of Buddhism congruent with "modern" understanding of religious roles in daily life as well as social engagement. On the other hand, I will also discuss some problems being inherent to the Western acculturation of the reformed and "engaged Buddhism." 1 The Ethical Activities of the SG in the World Ethical and Social Aspects of the Movement It is generally well known that the lay Buddhist organization, SG, as a whole has initiated wide and multifaceted activities even in an international level in order to transform its religious ideals into social reality, specifically in the field of educational, cultural, social, and peace-promoting programs. For this purpose it established educational institutes ranging from kindergartens to universities as well as research [End Page 59] institutes such as the Institute of Oriental Philosophy (founded 1961), the Boston Research Center for the 21st Century (founded 1993), the Toda Institute for Global Peace and Policy Research (founded 1996), and other centers for ecological researches. For promoting mutual respect and understanding through cultural expressions and exchanges several institutes have been established, like the Min-On Concert Association (founded 1963), the Tokyo Fuji Art Museum (founded 1991), and La Maison Littéraire de Victor Hugo in Bièvre, France (founded 1992). On a global level, its political involvement is, for a large part, situated as a NGO in the frame of the UNO and the UNESCO. With the help of the UNO, SG has organized all over the world expositions translating its concerns for peace, e.g., "Nuclear War: Threat to our World" and "War and Peace." With the Simon Wiesenthal Center it organized an exhibition "The Courage to Remember: Anne Frank and the Holocaust Exhibition." The issue of human rights is another of its major concerns. Commemorating the forty-fifth anniversary of the United Nations' adoption of the Universal Declaration of Human Rights, SG held an exhibition entitled "Toward the Century of Humanity: An Overview of Human Rights in Today's World" at the UN office in Geneva. Also, money received from fund-raising activities has been donated to the Office of the United Nations High Commissioner for Refugees and related agencies to provide medical supplies and food, and to support educational programs in the areas concerned. To expose the horrors of war, SG has also published life histories written by members about their sufferings in war: "Women against War," "Cries for Peace," and "Peace is our Duty." Segmental Differentiation of Organizational Structure To meet the requirements of functional differentiation of today's modern societal life SG is organized in a segmental and hierarchical structure. The basic structure is the regional units, organized in a hierarchical model, and all members are integrated "in each group" in their residence area. At the same time each member belongs to a specific "division" which is organized according to gender, age, and occupation. There are the four divisions of men, women, young men, and young women. Additionally there are divisions for school boys and girls, university students, as well as divisions according to occupation such as artists, lawyers, medical doctors, academics, and so on. These divisional differentiations reflect the need... (shrink)

Determinants of synesthetic color choice for the Japanese logographic script, Kanji, were studied. The study investigated how synesthetic colors for Kanji characters, which are usually acquired later in life than other types of graphemes in Japanese language , are influenced by linguistic properties such as phonology, orthography, and meaning. Of central interest was a hypothesized generalization process from synesthetic colors for graphemes, learned prior to acquisition of Kanji, to Kanji characters learned later. Results revealed that color choices for Kanji characters (...) depend on meaning and phonological information. Some results suggested that colors are generalized from Hiragana characters and Arabic digits to Kanji characters via phonology and meaning, respectively. Little influence of orthographic information was observed. The findings and approach of this study contributes to a clarification of the mechanism underlying grapheme-color synesthesia, especially in terms of its relationship to normal language processing.

Free will in intentional consciousness is exposed to skeptics since it was found that subconscious neural activities, what is called readiness potential, precedes the intention to an action. The question of whether free will is an authentic illusion has been argued not only in psychology but physics and philosophy. Most of scientists, however, think that the intentional consciousness who believes to have his/her own free will, is determined by readiness potential in advance, and that free will cannot coexist with determinism. (...) We here point out that knowing to be determined in advance cannot be verified till local event at a local site can be known from a different local site without disturbing the event. That is the assumption of locality. We here show that determinism, free will and locality are three essential elements in consciousness, and show that they constitute trilemma. The fact that one of three elements must be abandoned can lead to three types of consciousness. Absence of free will can constitute type I consciousness which is consistent with symptoms in autism spectrum disorder such as weakened theory of mind. Absence of determinism can constitute type II consciousness which is consistent with symptoms in schizophrenia such as thought insertion, self-other integration. Absence of locality can constitute type III consciousness which is consistent with typical people. We can find the entanglement of intentional consciousness with unconsciousness including readiness potential only in type III consciousness. Finally, we show that sense of agency and free will cannot be established until consciousness as an entanglement is implemented. (shrink)

Floridi’s infosphere consisting of informational reality is estimated and delineated by introducing the new notion of Typ-Ken, an undifferentiated amalgam of type and token that can be expressed as either type or token dependent on contingent ontological commitment. First, we elaborate Floridi’s system, level of abstraction (LoA), model, and structure scheme, which is proposed to reconcile ontic with epistemic structural reality, and obtain the duality of type and token inherited in the relationship between LoA and model. While we focus on (...) the ontological commitment that can negotiate and emphasize the discrepancy between type and token, we show that most research focusing on different hierarchical layers (type and token) has converged onto the flattened perspective of type and token to clarify the role of ontological commitment. We propose the idea of Typ-Ken to avoid this flattening. In addition, we elaborate Taddeo and Floridi’s criticism of approaches to the symbol grounding problem and show that their criticism based on the zero semantical commitment condition is specific to the agents affected by the flattening. We then take bird flocks as a metaphor for the living infosphere as if it had one mind. The knowledge recently yielded by image analysis indicates that it is difficult for previous flock models based on agents equipped with the flattening of local (token) and global (type) to show the special feature of a flock of the scale-free proportion (SFP). We show here that agents based on the Typ-Ken can reveal the SFP, which is the essential characteristic of the living infosphere. In other words, Typ-Ken is an expression for informational reality (LoA and model with ontological commitment) that can reveal seamless local and global interactions in the functioning of a flock or infosphere.

Determinants of synesthetic color choice for Japanese phonetic characters were studied in six Japanese synesthetes. The study used Hiragana and Katakana characters, which represent the same set of syllables although their visual forms are dissimilar. From a palette of 138 colors, synesthetes selected a color corresponding to each character. Results revealed that synesthetic color choices for Hiragana characters and those for their Katakana counterparts were remarkably consistent, indicating that color selection depended on character-related sounds and not visual form. This Hiragana–Katakana (...) invariance cannot be regarded as the same phenomenon as letter case invariance, usually reported for English grapheme-color synesthesia, because Hiragana and Katakana characters have different identities whereas upper and lower case letters have the same identity. This involvement of phonology suggests that cross-activation between an inducer brain region and that of the concurrent area in grapheme-color synesthesia is mediated by higher order cortical processing areas.

A modified form of Mach's principle is proposed, and its consequences are discussed.

Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict.
