This study seeks to demystify one of a niche subculture of extreme female fans and mavens known as “Fujoshi” who get really into animation, comic, novel and so on. They call themselves self-mocking term “Fujoshi” and are willing to draw⁄read fanzines that are an underground hobby focused on romantic or homosexual relationships between male characters from various media texts. In this paper, I describe how they construct their identities and social relations through narrative and practice. First I frame this work as an effort to think the differentiation between “self” and &ldquoidentity”. Then I show the core characteristic of “Fujoshi” groups is the issue of hiding identity. The assumption has been in subcultural studies that the embodied external identity display in the face of mainstream culture is foundational. But “Fujoshi” culture does it differently. Although they make their identities invisible in everyday lives, that hiding practice paradoxically makes their identities visible in “Fujoshi” community. The other area that I found interesting was their ironical communication. Because they believe that “Fujoshi” activities are considered to be inferior to the &ldquonormal” females, they express their identities self-deprecatingly. I think this practice is a defensive communication against prejudice and is also a strategy to present their identities paradoxically.

Processing fluency influences judgment as metacognitive cue. Laham, Koval, & Al-<br>ter (2012) demonstrated name-pronunciation effect whereby easy-to-pronounce (i.e.,<br>easy-to-process) names were judged more positively. In their study, however, the "pro-<br>nouncability" was not defined by objective criteria, which may cast doubt on the inter-<br>nal validity of the effect. To overcome this limitation, the present study replicated the<br>name-pronunciation effect by manipulating two objectively defined and well-established<br>pronouncability factors: within-item phonological similarity and phonotactic frequency<br>of the name. Phonological similarity is manipulated by making the constituent morae<br>share the same vowel or not. Phonotactic frequency is defined by a composite score of<br>mora, bi-mora and position-mora frequency. We asked participants to rate impression<br>of names, presenting nonwords as names of foreign person who would come to their of-<br>fice. The result indicated independent effects of phonological similarity and phonotactic<br>frequency with phonologically similar and low phonotactic frequency names being rated<br>negatively. The present study confirmed the internal validity of the name-pronunciation<br>effect in the previous study.

As the proverb “two heads are better than one” says, people often expect that collaborative activities bring about emergence of knowledge or ideas. In order to confirm whether there is actually the possibility of emergence through collaboration, the authors investigated actual collaborative activities in research & development processes based on the hierarchical interview method. First, a case study of developing a new impactful detergent was made in detail. As a result, three kinds of collaboration (interdepartmental collaboration, interdisciplinary one between two teams, and interdisciplinary one between two individual members) were observed. Especially, an interdepartmental collaboration was clarified to be significant in the case. Second, some cases of collaboration which were brought about in a relatively short time span were analyzed and, as a result, collaborative interactions in organizational knowledge creation were classified into three types. This study indicates that new ideas or knowledge can be emerged through collaboration in actual research & development processes.

Previous studies suggest, contrary to our naive understanding that ideas for innovation are generated by supply-side such as product developers, that the ideas can be actually generated by consumers, especially the users called “early adopters” who keep some distance from product developers in product adoption and knowledge. This research tested, through two experiments for idea generation, which was more important to idea generation for innovation; information, i.e. preceding ideas about new usage of a product, or individual cognitive feature, i.e. innovator or early adopter. One experiment was conducted with general consumers, taking as an example idea generation for new products and services related to information technology, and the other was done with R&D members in a real company. The results suggest that information, i.e. preceding ideas about new usage of a product, was important to generation of creative ideas for innovation and, at the same time, that it was early adopters rather than innovators who could make effective use of the information in the idea generation: This is considered to call for a rethink of “sticky information hypothesis” by von Hippel (1994), which claims the dominant role of information in innovation. This research also suggests, through an additional experiment for information retrieval, that tendencies of innovators to avoid communication with people other than innovators and to think much of function and spec that a product has may degrade their performance in creative idea generation.

This study investigated the effect of moral foundation and feeling of disgust toward acriminal case on non-professional legal decisions. Three hundred and sixty participantswere asked to read a fictional story about a murder attempt case and rated a possi-bility that a defendant, who had denied all charges against the case, would be judgedas guilty. Participants were also rated a degree of regrets about their decision if thetruth would be either guilty or not guilty. The degree of physical injury of a victim wasvaried in accordance with three conditions (i.e., minor, heavy, and permanent damage).The analysis revealed that participants who put much value on not harming others feltdisgust toward the criminal case, and that resulted in higher ratings of possibility thatthe defendant would be judged as guilty. In addition to that, as the degree of physi-cal injury of the victim got severer, the ratings of the possibility also got higher, andparticipants felt less regrets of their decision even if the defendant was actually nota real perpetrator and thus they made Type II error. We discussed characteristics ofnon-professional legal decisions from both theoretical and practical perspectives.

Some people with pervasive developmental disorder (PDD) can hardly express their own thoughts in language. Sometimes, they have been considered as a communication disorder. However, since the word “communication” is usually defied as an interaction between at least two persons, it is doubtful to attribute problems happened within a particular communication to one side. In this study, I collected text data from a mi-croblog of one person who has been diagnosed as PDD and having difficulty to express her own thoughts in language, in order to investigate how the microblog had changed the way of communications. The results of the text data analysis showed that the par-ticipant expressed what she wanted to say by referring and utilizing remarks of others. The possibility and implications of removing the difficulties from their communication through the process of “curation” was discussed.

Children with autistic spectrum disorders (ASD) are diagnosed by deficits in social interaction and linguistic skills, and restricted interests and stereotypic pattern of behavior. They have difficulties in motor, perceptual, cognitive, linguistic functions. In the present article, we proposed the comprehensive view point for understanding children with ASD; Relationships between various psychological functions, interaction between individual and environment, developmental mechanisms and developmental change by the appropriate intervention. We first described the profiles of ASD, prevalence, diagnostic criteria and resent assessment measures with the possibilities for very earlier screening in one year. Recent advancement of early intervention studies and the guideline for the application showed that early intensive treatment, pivotal behavior treatment, structured environment and parent-support program were effective for promoting the development of children with ASD. The developmental mechanism and treatment curriculum were analyzed in positive social interaction, joint attention, imitation, auditory comprehension, vocal production, verbal behavior and conversation. Children with high-functioning autism and Asperger syndrome have deficits in understanding ambiguous context, higher-ordered linguistic rules, social interaction and other's “mind”. We reviewed the treatment studies for these difficulties and found that the effective treatment included the “visualized” procedures, because children with ASD have “strength” in visual thinking. Video modeling and in-vivo role playing were effective for generalizing the acquired social skills to everyday life situation. We, as scientist ⁄ practitioner, discussed the future direction of evidence-based studies for developing children with ASD.

There are some children with reading difficulties in the regular class. They seem to have some problems in their perceptual or cognitive skills involved with reading process. In this study, we developed the multi-media learning support system “Touch & Read” for assisting their reading process. The system can zoom up the text, highlight the line in it, and read out it to present the information auditorily. Introducing this system to the regular class, we investigated the way of the learning support for the children with reading difficulties. Ahead of the introduction, we conducted the test to survey the children's decoding skills and visuoperceptual functions and identified the causes of reading difficulties. We provided the Touch & Read to children for their learning in the regular class, and observed how the children with reading difficulties used the system. As a result, it was suggested that children could use the system to compensate their perceptual or cognitive skills and achieve more efficient learning outcomes.

This paper analyzes the relationship between participation and learning represented in ethnographic case studies of ten informants aged 23-59 participating in a common-based peer production site, the FabLab Kamakura community. Digital-based personal fabrication is a new wave culture of mavens, who are devoted to alternatives to massproduction, and are on a mission “to make (almost) anything”. FabLab Kamakura is a valuable venue for exchanging information about, for example, digital tools, Arduino,crafts, textiles, and so on. First we frame this work as an effort to think about their participation and learning using the concept of “wildfire activity theory”(Engeström,2009) and “legitimate peripheral participation (LPP)”from Lave and Wenger (1991). Then we argue an overview of FabLab culture in Japan and at FabLab Kamakura. Us-ing SCAT methodology (Otani, 2011), we group our findings in two different categories:(1) learning through participation in FabLab Kamakura, (2) the visualization of weakties and mobility through participation in wildfire activities. We conclude that partic-ipants at FabLab Kamakura are producing and designing available artifacts for their lives and works, and in doing so, what they are designing is the physical manifestation of their very thoughts.

People often lose their way when they are trying to find a particular place. In Japan we call such a person “houkou onchi”. This is a common Japanese expression which means to have no sense of direction. Whether people are “houkou onchi” or not seems to be related to the quality of their cognitive maps, their ability to navigate and the navigation processes they employ. This research aims to reveal what “houkou onchi” is. To investigate this, I have focused on the difference between the navigation processes of people who are good and poor at navigating.The subjects undertook a series of tasks which involved watching video films of routes (taken from a moving car). I have analyzed their learning processes and their navigation simulation performance to understand how they interact with the environment they are moving through, while they are acquiring and using information. I have observed a number of features of houkou onchi. Such people do not interact well with the environment during route learning and navigation. They do not always focus on the relevant information required for navigation when they learn the route. Moreover, they cannot form useful cognitive maps after they have learnt the route, and they cannot effectively use such cognitive maps to navigate in space they have already visited. I have observed various kinds of interaction with the environment, and I will discuss the importance of this interaction to navigation.

This study investigated the creative expertise of artists who had been making art for many years. In an initial study, we interviewed four artists at different stages of their careers about their previous artworks to investigate how they made them and how they changed in the course of their making. We asked, for instance, about their concept of each artwork, when and how a new series of artworks emerged, and so on. It was revealed that experienced artists formed their artistic vision (i.e., their long-term intention or main theme related to making art) after changing series of artwork several times, and then created artworks based on it. On the other hand, younger artists did not recognize their artistic vision yet, making artworks based on their temporary interests. In a second study, nine professional artists with more than 10 years of experience were interviewed about their whole body of artworks to identify how they became creative experts and how their artistic vision was formed. As a result, it appeared that there are three periods in creative expertise: the first is “being constrained to external criteria”; the second is “forming their own internal criteria”; and the third is “generating harmonious creations with the artistic vision.” In sum, when the artists were young, they made artworks based on external criteria. Later on, they recognized the limitations of this approach, and started to focus on internal criteria. Finally, on average about 13 years after beginning their artistic careers and creating several series of artworks, artists formed a personal artistic vision. At that point they were confidently able to make original artworks.

This commentary gave some additional findings and implications for “symmetrical bias (or bidirectional relation)” from a viewpoint of Contextual Behavioral Science, in particular, Relational Frame Theory and Acceptance and Commitment Therapy. The given findings were related with a) the transformation of stimulus function through bidirectional relation in persons with specific phobia or mental disorder, b) the emergence or non-emergence of bidirectional relation influenced by baseline-training reversals or protocols in matching-to-sample procedure, and c) the emergence or non-emergence of bidirectional relation in infants or nonhuman subjects. Furthermore, the given implications were related with d) necessity of balancing between abduction and induction, particularly identifying and cumulating the manipulable variables inductively, e) prevention of confusing explanation with cause through symmetrical biases, and f) clarification of own ”purpose and value”, in pursuing symmetry bias or bidirectional relation as one of most fundamental processes in human cognition.

Previous studies (Cosmides, 1989, Cosmides & Tooby, 1989) have shown the Cheater Detection Module (CDM) to be an adaptive heuristic within social environments, and how it can improve human reasoning in many social exchange contexts. The purpose of this study is to examine the effects of the CDM on problem solving. To that aim, the ‘30 dollar room’ problem (Isaak & Just, 1992) is employed, which involves a social exchange context. Generally speaking, we use heuristics to efficiently solve normal problems. However, this particular problem can be considered to be a typical insight problem. While heuristics can function effectively in practical contexts, they can be obstacles to solving insight problems (Knoblich, 1999; Hiraki & Suzuki, 1998). We hypothesize that the CDM will make it difficult to find the correct answer for this insight problem. In order to investigate this hypothesis, we compare solution rates for the standard ‘30 dollar room’ problem with isomorphic problems that do not involve ‘social exchange’ contexts. The results indicate that the solution rates for the isomorphic problems were higher than for the standard version of the problem. The results are supportive of our hypothesis. The results indicate that there are situations in which the CDM, a cognitive system that has emerged in adaptation to social environments, has a negative influence as a cognitive constraint.
