Myhill-Shepherdson property in recursive function theory states that extensional effective program transformations determine continuous operations on partial functions. Case showed that this property fails to characterize acceptability of numberings of partial recursive functions. In this note we present a higher type analogue to Myhill-Shepherdson property. Our purpose is to show that higher type Myhill-Shepherdson property characterizes weak acceptability under a natural condition.

Every acceptable numbering of an effective domain is complete. Hence every effective domain admits the 2nd recursion theorem of Eršov[1]. On the other hand for every effective domain, the 1st recursion theorem holds. In this note, we establish that for effective domains, the 2nd recursion theorem is strictly more general than the 1st recursion theorem, a generalization of an important result in recursive function theory.

This paper reports our research efforts on social robots that recognize interpersonal relationships. These investigations are carried out by observing group behaviors while the robot interacts with people. Our humanoid robot interacts with children by speaking and making various gestures. It identifies individual children by using a wireless tag system, which helps to promote interaction such as the robot calling a child by name. Accordingly, the robot is capable of interacting with many children, causing spontaneous group behavior from the children (...) around it. Here, group behavior is associated with social relationships among the children themselves. For example, a child may be accompanied by his or her friends and then play together with them. We propose the hypothesis that our interactive robot prompts a child’s friends to accompany him or her; thus, we can estimate their friendship by simply observing their accompanying behaviors. We conducted a field experiment for two weeks in a Japanese elementary school to verify this hypothesis. In the experiment, two “Robovie” robots were placed where children could freely interact with them during recesses. As a result, we found that they mostly prompted friend-accompanying behavior. Moreover, we could estimate some of their friendly relationships, in particular among the children who often appeared around the robot. For example, we could estimate 5% of all friendships with 80% accuracy, and 15% of them with nearly 50% accuracy. Thus, this result basically supports our hypothesis on friendship estimation from an interactive humanoid robot. We believe that this ability to estimate human relationships is essential for robots to behave socially. (shrink)

This paper presents a cross-cultural study on peoples’ negative attitude toward robots. 467 participants from seven different countries filled in the negative attitude towards robots scale survey which consists of 14 questions in three clusters: attitude towards the interaction with robots, attitude towards social influence of robots and attitude towards emotions in interaction with robots. Around one half of them were recruited at local universities and the other half was approached through Aibo online communities. The participants’ cultural background had a (...) significant influence on their attitude and the Japanese were not as positive as stereotypically assumed. The US participants had the most positive attitude, while participants from Mexico had the most negative attitude. The participants from the online community were more positive towards robots than those not involved. Previous experience in interacting with Aibo also had a positive effect, but owning an Aibo did not improve their attitude. (shrink)

To investigate whether people with social anxiety have less actual and “anticipatory” anxiety when interacting with a robot compared to interacting with a person, we conducted a 2 × 2 psychological experiment with two factors: social anxiety and interaction partner. The experiment was conducted in a counseling setting where a participant played the role of a client and the robot or the confederate played the role of a counselor. First, we measured the participants’ social anxiety using the Social Avoidance and (...) Distress Scale, after which, we measured their anxiety at two specific moments: “anticipatory anxiety” was measured after they knew that they would be interacting with a robot or a human confederate, and actual anxiety was measured after they actually interacted with the robot or confederate. Measurements were performed using the Profile of Mood States and the State–Trait Anxiety Inventory. The results indicated that participants with higher social anxiety tended to feel less “anticipatory anxiety” and tension when they knew that they would be interacting with robots compared with humans. Moreover, we found that interaction with a robot elicited less tension compared with interaction with a person regardless of the level of social anxiety. (shrink)

Negative attitudes toward robots are considered as one of the psychological factors preventing humans from interacting with robots in the daily life. To verify their influence on humans‘ behaviors toward robots, we designed and executed experiments where subjects interacted with Robovie, which is being developed as a platform for research on the possibility of communication robots. This paper reports and discusses the results of these experiments on correlation between subjects’ negative attitudes and their behaviors toward robots. Moreover, it discusses influences (...) of gender and experience of real robots on their negative attitudes and behaviors toward robots. (shrink)

We found that children sometimes abused a social robot placed in a shopping mall hallway. They verbally abused the robot, repeatedly obstructed its path, and sometimes even kicked and punched the robot. To investigate the reasons for the abuse, we conducted a field study in which we interviewed visiting children who exhibited serious abusive behaviors, including physical contact. We analyzed interview contents to determine whether the children perceived the robot as human-like, why they abused it, and whether they thought that (...) the robot would suffer from their abusive behavior. We obtained valid interviews from 23 children over 13 days of observations. We found that 1) the majority of the children engaged in abuse because they were curious about the robot’s reactions or enjoyed abusing it and considered it human-like, and 2) about half of them believed the robot was capable of perceiving their abusive behaviors.

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.

In this philosophical exploration, we investigate the concept of robotic moral environment interaction. The common view understands moral interaction to occur between agents endowed with ethical and interactive capacities. However, recent developments in moral philosophy argue that moral interaction also occurs in relation to the environment. Here conditions and situations of the environment contribute to human moral cognition and the formation of our moral experiences. Based on this philosophical position, we imagine robots interacting as moral environments—a novel conceptualization of human–robot (...) moral interaction with an inherent capacity for moral augmentation. To explicate this idea, we first define moral environments as moral systems providing moral affordances. We then intuit and explicate two constitutive conditions of moral environments: the environment’s moral ambiance and its moral atmosphere and compare them with real-life cases of moral environments—the moral landmarks. Based on these explications, we construct several explanatory cases to illustrate robots interacting as moral environments. Lastly, we set to evaluate the ethical challenges and wider social ramifications of using moral environment robots in the public space. (shrink)

This study investigates the influence of a robot's speech rate. In human communication, slow speech is considered boring, speech at normal speed is perceived as credible, and fast speech is perceived as competent. To seek the appropriate speech rate for robots, we test whether these tendencies are replicated in human-robot interaction by conducting an experiment with four rates of speech: fast, normal, moderately slow, and slow. Our experimental results reveal a rather surprising trend. Participants prefer normal and moderately slow speech (...) to fast speech. A robot that provides normal or moderately slow speech is perceived as competent. We further study how context affects this perception. In a situation where the robot and participants talk while walking, we found that slow speech was the most comprehensible. In addition, slow speech is subjectively perceived as good as moderately slow and normal speech. Keywords: Human-robot interaction; speech rate. (shrink)

Young children generally learn words from other people. Recent research has shown that children can learn new actions and skills from nonhuman agents. This study examines whether young children could learn words from a robot. Preschool children were shown a video in which either a woman or a mechanical robot labeled novel objects. Then the children were asked to select the objects according to the names used in the video. The results revealed that children in the human condition were more (...) likely to select the correct objects than those in the robot condition. Nevertheless, the five-year-old children in the robot condition performed significantly better than chance level, while the four-year olds did not. Thus there is a developmental difference in children’s potential to learn words from a robot. The results contribute to our understanding of how children interact with non-human agents. Keywords: developmental cybernetics; word learning; social cognition; cognitive development. (shrink)

A great deal of research has been performed recently on robots that feature functions for communicating with humans in daily life, i.e., communication robots. We consider it important to develop methods to measure humans’ attitudes and emotions that may prevent them from interaction with communication robots, as indices to study short-term and long-term interaction between humans and communication robots. This study is aimed at exploring the influence of negative attitudes toward robots, focusing on applications of communication robots to daily-life services. (...) First, a scale of negative attitudes toward robots consisting of three subordinate scales, “negative attitudes toward situations of interaction with robots,” “negative attitudes toward the social influence of robots,” and “negative attitudes toward emotions in interaction with robots,” was developed based on a data sample comprising of 263 Japanese university students. This scale was administered to 240 Japanese university students to confirm its validity and reliability. In this paper, we report on the results of analyses of these data samples. Moreover, we discuss some future problems including a comparison of attitudes toward robots between nations. (shrink)

In order to investigate the influence of participants’ age on their image of robots in Japan, a pilot research was completed by 371 visitors at a robot exhibition held at a commercial facility in Japan, based on the questionnaire consisting of four open-ended questions. The comparison of younger, adult, and elderly groups, found that: in the younger age group, images of robots are ambiguous about near future assumptions, preferences, and antipathy, the adult group assumes that communication robots will appear in (...) the near future, but actually expects robots to function in non-communication tasks such as household duties and dangerous tasks, and experiences great anxiety and fear about social relationships between robots and humans, the elderly group assumes that both communication and non-communication robots will appear in the near future, but actually expects robots to function in communication tasks such as service in public settings and providing care at home or in welfare facilities, and is very concerned about the physical and ecological damage that robots may cause. Although the pilot study had a problem of sample bias on participant selection and distributions of gender and age, it can lead to some predictions on social acceptance of robots in Japan.

Previous research has shown that although infants follow the gaze direction of robots, robot gaze does not facilitate infants’ learning for objects. The present study examined whether robot gaze affects infants’ object learning when the gaze behavior was accompanied by verbalizations. Twelve-month-old infants were shown videos in which a robot with accompanying verbalizations gazed at an object. The results showed that infants not only followed the robot’s gaze direction but also preferentially attended to the cued object when the ostensive verbal (...) signal was present. Moreover, infants showed enhanced processing of the cued object when ostensive and referential verbal signals were increasingly present. These effects were not observed when mere nonverbal sound stimuli instead of verbalizations were added. Taken together, our findings indicate that robot gaze accompanying verbalizations facilitates infants’ object learning, suggesting that verbalizations are important in the design of robot agents from which infants can learn.

This paper reports the results of questionnaire-based research conducted at an exhibition of interactive humanoid robots that was held at the Osaka Science Museum, Japan. The aim of this exhibition was to investigate the feasibility of communication robots connected to a ubiquitous sensor network, under the assumption that these robots will be practically used in daily life in the not-so-distant future. More than 90,000 people visited the exhibition. A questionnaire was given to the visitors to explore their opinions of the (...) robots. Statistical analysis was done on the data of 2,301 respondents. It was found that the visitors’ opinions varied according to age; younger visitors did not necessarily like the robots more than elderly visitors; positive evaluation of the robots did not necessarily conflict with negative evaluations such as anxiety; there was no gender difference; and there was almost no correlation between opinions and the length of time spent near the robots.

In this paper, we move toward offering psychological benchmarks to measure success in building increasingly humanlike robots. By psychological benchmarks we mean categories of interaction that capture conceptually fundamental aspects of human life, specified abstractly enough to resist their identity as a mere psychological instrument, but capable of being translated into testable empirical propositions. Nine possible benchmarks are considered: autonomy, imitation, intrinsic moral value, moral accountability, privacy, reciprocity, conventionality, creativity, and authenticity of relation. Finally, we discuss how getting the right (...) group of benchmarks in human–robot interaction will, in future years, help inform on the foundational question of what constitutes essential features of being human.

BackgroundThis study aimed to determine the elements and the extent of information that child participants and their parents would like to read in an informed assent form /informed consent form of a pediatric drug trial.MethodsA descriptive survey was conducted to determine the perceived importance of each element of the ICF content from child participants and their parents who underwent informed assent/consent of a multi-center pediatric drug trial. The respondents were asked to indicate the level of importance of each item in (...) a questionnaire, by giving a rating scale from 1 to 5.ResultsA total of 22 families, 17 child participants with the diagnosis of hematology or oncology diseases and 27 parents, were enrolled. Among 30 items, risk–benefit aspects were perceived to be of most concerning items from both child participants’ and parents’ viewpoint. None of the items were considered ‘slightly important’ or lower by more than 20% of the respondents.ConclusionsFor pediatric drug trials, risk–benefit information should be made a salient feature of an IAF/icf. This empirical data could help related stakeholders arrange essential information in order of importance and tailor an IAF/icf to better suit child participants’ and parents’ needs, particularly for pediatric drug trials involving children with the diagnosis of hematology or oncology diseases.

Young children often treat robots as social agents after they have witnessed interactions that can be interpreted as social. We studied in three experiments whether four-year-olds from three cultures and adults from two cultures will attribute ownership of objects to a robot that engages in social gaze with a human. Participants watched videos of robot-human interactions, in which objects were possessed or new objects were created. Children and adults applied the same ownership rules to humans and robots – irrespective of (...) whether the robot engaged in social gaze or not. However, there was cultural variation in the types of ownership rules used. In Experiment 3, we removed further social cues, finding that just showing a pair of self-propelled robot-arms elicited ownership attributions. The role of social gaze in social attributions to robots and cross-cultural differences in ownership understanding are discussed. (shrink)

It will be seen how in place of the wealth and poverty of political economy come the rich human being and rich human need. The rich human being is simultaneously the human being in need of totality of human life-activities — the man in whom his own realization exists as an inner necessity, as need. Marx, Economic and Philosophical Manuscripts of 1844 Svetaketu abstained from food for fifteen days. Then he came to his father and said, `What shall I say?' (...) The father said: `Repeat the Rik, Yagus, and Saman verses.' He replied, `They do not occur to me, Sir.' The father said to him... `Go and eat! Then wilt thou understand me.' Then Svetaketu ate, and afterwards approached his father. And whatever his father asked him, he knew it all by heart....

This essay offers a fresh interpretation of Bhartr̥hari’s concept of “insight”, and of its identification as the object of a sentence in the second kāṇḍa of the Vākyapadīya. Earlier scholars dealing with this topic disagreed on three main points: whether an epistemologically rigorous concept of insight can be found in Bhartr̥hari’s work, or if the notion remains irrevocably vague and equivocal; whether the concept of pratibhā primarily belongs to linguistics, or to action theory; whether Bhartr̥hari’s identification of insight as the (...) object of a sentence should be taken literally or figuratively. Starting from a close analysis of all passages in Bhartr̥hari’s work mentioning pratibhā, I identify, first of all, a univocal understanding of insight, valid throughout the Vākyapadīya, as immediate cognition informed by verbal transmission, in other words as a form of practical knowledge, non-representational yet essentially productive and dynamic. Showing, on this basis, how Bhartr̥hari’s understanding of language at the level of sentences is pragmatic rather than referential, I demonstrate, against the view prevalent in the late grammatical tradition, that a literal interpretation of his provocative statement on pratibhā as vākyārtha remains perfectly plausible. This thesis is further corroborated by the consideration of post-Bhartr̥hari philosophical sources elaborating on his ideas, which allow us better to understand in what sense pratibhā can legitimately be thought of as cognition “without an object”.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.1 (2001) 161-181 [Access article in PDF] Translating Liberty in Nineteenth-Century Japan Douglas Howland A concept of liberty was but one element of the Japanese engagement with western political theory after the Perry intrusion of 1853, when United States warships led by Commodore Matthew Perry forced Japan to negotiate a commercial treaty with the U.S. This scandal, which ultimately led to the Meiji (...) Restoration of 1867, immediately reorganized scholarly priorities among those intellectuals interested in western knowledge and technology. Western learning under the "feudal" Tokugawa regime (1603-1867) was organized as "Dutch studies" because the Dutch were the sole European trading partner of Japan from 1641 to 1854. Dutch studies paid particular attention to European mathematics, astronomy, geography, natural history, and the Dutch language. The Perry intrusion, however, prompted the rise of "western learning": language study quickly expanded to include English, French, and German; and the content of learning emphasized European law and political philosophy. But the concepts that defined this content of western thought did not translate well; they did not fit naturally with existing Japanese concepts. Hence the translation of western political theory necessitated the invention of new terminology with which to engage the new political language. Accordingly, Japanese efforts to translate western political theory must be understood as both problems of language, the creation and circulation of new concepts, as well as problems of action, and the usage of new concepts in debates about the programs and policies to be implemented in a "westernizing" Japan. 1 [End Page 161]The scholars who figure in this essay--Kato Hiroyuki, Tsuda Mamichi, Nishi Amane, Kanda Takahira, Fukuzawa Yukichi, and Nakamura Keiu--were all key figures in the intellectual passage from Tokugawa to Meiji, from Dutch studies to western learning. They began their careers in the Tokugawa institute for Dutch studies; most traveled to Holland, England, or the United States during the 1860s; and after the Meiji Restoration they became intellectual and educational leaders under the new administration. 2 In addition to founding private academies or filling prominent government posts, they created the first literary society, the Meiji Six Society (named after the year of its founding, the sixth year of the Emperor Meiji's reign, 1873), which sponsored public debates, published these proceedings in the Meiji Six Journal, and so hoped to promote enlightenment among the Japanese people. In addition to introducing public debate to Japan, this transitional intelligentsia was involved in the fundamental work of creating the language in which to raise issues of constitutional form or personal freedoms. In their translations of western texts and original texts about western law and political philosophy they created the neologisms to translate western concepts and participated in the standardization of terminology that made western knowledge coherent.The two concepts discussed in this essay, which were among the first to figure prominently in intellectual debates of the early 1870s, were "liberty" and "religion," the pairing of which in the debate over freedom of religion from 1872 to 1874 was crucial in defining a Japanese conception of liberty. Although religious liberty arose in western Europe as a result of the conflict between church and state authorities, the issue in Japan was a direct challenge to the new central government's attempt to decree a national Shinto doctrine in 1868. As the sole case of unanimous support for personal liberty among the transitional intelligentsia, the debate over freedom of religion determined key distinctions between private and public behavior that defined the Japanese conception of "liberty" for the duration of Japan's imperial constitution (to 1945). As a right of individuals, liberty resided in the exclusively private domain of thought, conscience, and religious faith. As a public matter the people's liberty necessarily gave way to government maintenance of public order.In part this essay responds to the work of Japanese philologists who study the translation and standardization of modern Japanese vocabulary. Much of this work is based on dictionaries; a word is said to have become standard as it appears in greater numbers of Japanese-Chinese, Japanese... (shrink)
