Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments (...) about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task. (shrink)

Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target . Using this new measure, (...) we found that target misses were subjectively indistinguishable from physical absence when contrast reduction, backward masking and flash suppression were used, whereas confidence was appropriately modulated when dual task, attentional blink and spatial uncertainty methods were employed. These results show that failure of visual perception can be identified as either a result of perceptual or attentional blindness depending on the circumstances under which visual awareness was impaired.

This study developed an emotional vulnerability scale and examined its reliability and validity with a sample of university students. In health psychology, a measurement of emotional pain can contribute to the prevention and improvement of physical and mental health problems in daily life. We collected data from 361 Japanese university students. From preliminary interviews with 20 participants, 42 semantic units were extracted. For scale development, a questionnaire survey was conducted using the 42 extracted categories, and exploratory and confirmatory factor analyses (...) were performed. Four factors emerged, which were both reliable and valid: “vulnerability toward criticism or denial,” “vulnerability toward worsening relationships,” “vulnerability toward interpersonal discord,” and “vulnerability toward procrastination and emotional avoidance.” This scale can be useful to understand vulnerability in everyday situations and grasp the vulnerable conditions experienced by individuals. This can help prevent stress responses and mental health problems, which are valuable contributions to health psychology. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Reception of Husserl’s Phenomenology in Japanese PhilosophyShinji HamauzuWhen we talk about the influence of Husserl’s phenomenology, we should discuss in advance what can justify this talk. When we mention keywords— for instance, intuition of essence, intentionality, inner time-consciousness, rigorous science, natural attitude, phenomenological reduction, transcendental phenomenology, noesis-noema, my living body, genetic phenomenology, empathy, intersubjectivity, life-world, and so on—which keywords should we use when talking about the influence Husserl’s (...) phenomenology had on Japanese philosophy? But we should also ask the following question as well: Which of Husserl’s texts could be available for scholars of Japanese philosophy? Interestingly, there were few works, beyond attending Husserl’s lectures, that one could access, because he only published six books and six articles while he was alive. After Husserl died in 1938, many manuscripts were rescued from the Nazi’s hands and placed at Leuven University in Belgium where the Husserl Archive was first established. The manuscripts were edited and published as Husserliana beginning in 1950 (which now has 42 volumes). Given this, we can think of Husserl’s work as consisting of two periods: the period before and the period after the publication of Husserliana.I myself am interested in the problem of “intersubjectivity” within Husserl’s phenomenology. It is on the one hand the problem of “other-experience (Fremderfahrung)”—i.e., “how I experience the other”—which is the problem of other-experience in the empirical dimension. But it is on the other hand the problem of “intersubjective constitution”—i.e., “how the objective world is the correlate of intersubjective constitution through other-experience,”1 which is the problem of how the other participates in the transcendental dimension. It is characteristic of Husserl’s phenomenology that these two problems are discussed together inseparably. [End Page 1]The manuscripts on the problem of “intersubjectivity” from 1905 to 1935 are collected in volumes XIII to XV of Husserliana. Although the fifth meditation of Cartesian Meditations (first published in French translation in 1931) is often mentioned as the representative work on this theme, it is no more than the tip of the iceberg after Husserl struggled for many years on this problem. The genesis of this theme in the manuscripts dates back to 1905 when terms such as “other” (ein Anderer) and “foreign” (fremd) appeared in manuscript 1, or terms such as “empathy” (Einfühlung) and “intersubjective” appeared in manuscript 2. Husserl wrote later that he had discussed this theme to a relatively large extent in the lecture Fundamental Problems of Phenomenology (Hua XIII) in 1910–1911. In the period of 1905–1910, after the “problem of intersubjectivity” was first introduced, we can also find the idea of “phenomenological reduction” appear for the first time in the literature. This tells us that the problem of intersubjectivity and the idea of phenomenological reduction were born as two sides of the same coin.When Husserl’s phenomenology was first introduced to Japan, Japanese scholars were already reading the first volume of Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy, where the “intersubjective world” is thought to refer to a “correlate of experience mediated by empathy,”2 and so the task is to clarify the “intersubjective constitution of the objective world.”3 However, when we consider Husserl’s influence in the history of Japanese philosophy and examine whether the problem of intersubjectivity is discussed as a fundamental problem of philosophy, it can be doubted, in my opinion, whether or not there were any researchers who ever faced this problem seriously. In what follows, I survey several generations of philosophers in Japan who engaged with Husserl’s rehabilitation, to investigate the problem of intersubjectivity in his reception and extent of his influence.Nishida Kitarō’s Interest in PhenomenologyNishida Kitarō (1870–1945) looked back at the revision of his first book in 1936 and wrote,The standpoint of this book [An Inquiry into the Good (1911)] is that of consciousness, which might be thought of as a kind of psychologism... I came to realize that it is not that experience exists because there is an individual, but that an individual exists because there is experience. I... (shrink)

While there are many studies that address how well Japanese companies have adopted explicit CSR practices, our understanding of their own views on such practices is still limited, particularly of the difference in their views before and after the process of making implicit CSR explicit. The present research thus aims to address this apparent change by providing comparative case studies of two Japanese companies selected from two different time periods. The findings indicate there is a continuity observable in the mindset (...) of these companies not a change. This contradicts existing literature and suggests that the process of making CSR explicit has not been accompanied by any real change in their mindset. The result shows that ethically questionable practices have been going on behind the explicitly articulated CSR policies and implies the difficulties of delegating the power to address societal issues to business organisations. This is important particularly now when the expectations of the public regarding the responsibilities of business towards society are on the rise. (shrink)

Business Ethics: A European Review, EarlyView.

The ignorance of Helsinki declaration is continuing in Japan for approximately 20 years. More than 400 children including preschoolers with developmental conditions including temper tantrums, hyperactivity, and/or autistic characteristics have been already operated. The cranioplasty for isolated mild trigonocephaly had been empirically introduced by a physician to re-establish the brain spatial environment, and a government-granted and multi-centered clinical observation study is now in operation without scientific verification of the procedure’s validity. The characteristic of the skull shape are too mild and (...) sometimes too subtle to be recognized by the parents and health checkup doctors. A physician may tentatively and extraordinarily use an unproven procedure in exceptional circumstances where proven and effective interventions do not exist. However, the intervention must as soon as possible be subjected to scientific scrutiny according to ethical principles in order to stop the utilization in case of misprediction. (shrink)

近代日本において一様に捉えきれない多様な「悪」の姿と、それがどのように扱われたのかを、イデオロギーと実践の双方の面から描く。.

Since the collapse of Japan's bubble economy in the early 1990' s, the Japanese economy has only recovered slightly. This has direct implications for employment. Both the seniority wage system and the lifetime employment system, which were popular during the period of economic growth in Japan, unavoidably changed to an outcome-wage system. Now there is greater mobility in employment, increased use of nonregular employees, and diversed working patterns. The problem of karoshi – a potentially fatal syndrome resulting from long work (...) hours – has been known since the early 1980s. This problem has become more serious in recent years. The purpose of this article is to provide an overview of the economic and employment conditions in Japan, as well as to examine the working lifestyle of Japanese men and its connection to "karoshi." It is argued that the long work hours are not the preference of individuals, but rather the result of the adaptation to the work environment, and; solving this problem requires re-conceptualization of workers' human rights on the part of both companies and the society as a whole.

In The Human Condition, Hanna Arendt explained the rise of the social realm during the early modern period from the ancient dichotomy between the public and the private domains. For her, the rise was relevant to the establishment of political economy. This establishment was also linked with the intellectual change of a non-Western region. When Japanese intellectuals began importing Western political economy, they confronted a problem of how to fit that science to the Japanese situation, which they saw as having (...) no public realm composed of equal citizens. Although scholars have studied the reception of political economy in Japan, how the intellectuals transformed their understanding of society remains a research gap. I argue that some intellectuals in Japan thought that in order to provide space for the concept of political economy, they needed to create both a public and a social realm, and this caused some tension – a tension different from that in the European context. Indeed, Japanese people had a unique reception of Adam Smith’s political economy. Especially after Westernization (or the Meiji Restoration) began in 1868, the concept of political economy began to spread throughout Japan. Yukichi Fukuzawa (1835–1901), the most influential Enlightenment thinker in the Meiji era, denied the traditional, neo-Confucian view of economics and declared that the pursuit of wealth should be the goal of society; he thus introduced space for the concept of political economy into Japan. This space was regarded as troublesome, and Shigeki Nishimura (1828–1902), an advocate of national morality, challenged the concept, arguing that society should be based on ethics, not on the pursuit of wealth.

More attention needs to be given to Adam Smith's view of South America. Although scholars have elucidated Smith's view of colonization, these studies have not fully clarified how Smith was influenced by the depiction of societies in South America from travel books. Though he read travel books on South America, Smith does not necessarily follow their original description of the societies found there. Instead, he sometimes distorted the original in consideration of the effects of colonization. To evaluate the impact of (...) colonization, he supposed that societies in South America were not civilized, so colonized societies could be seen as part of the process of civilization. However, he did not belittle precolonial societies. He emphasized the moral quality of the so-called savage people. As I argue in this paper, he had at least two criteria in evaluating society. In addition to economic development, Smith also recognized moral degradation as part of social development. Smith evaluated s... (shrink)

Intersectionality is a travelling theory; now enjoying significant contemporary visibility and popularity in the feminist blogosphere, it has moved across disciplines and borders in ways that are quite distinct from the scholarly critique developed by Kimberlé Crenshaw some time ago. In this article, I consider how intersectionality is translated, and retheorised, as an intertwined set of everyday knowledges and associated governmental practices that both echo and diverge from some of the complexities and politics of its wide-ranging scholarly uptake. Drawing on (...) interviews with self-identifying feminists in a pilot project mapping contemporary Australian digital feminisms, this article explores two overarching patterns in intersectionality’s mobilisation. First, the shift to understanding intersectionality as an everyday conceptual grid plotting women’s differences along one axis, and measuring relative privilege and disadvantage on the other, recentring whiteness and liberal multicultural models of diversity and inclusion. Second, the transformation of intersectionality into an abstract, individualistic model of conduct, involving the citation and classification of ‘white feminist’ behaviour elsewhere, in frequent judgments on US celebrity culture. As such, intersectionality, while seemingly popular, often remained curiously ‘theoretical’ and divorced from embodied, everyday practices. I suggest in what follows that such a model of intersectionality raises questions of the commercial, racialised, political and mediated conditions that shape the theory’s visibility and materialisation.

Theories of institutions can be classified into two broad approaches: institutions-as-rules and institutions-as-equilibria. According to the first approach, institutions are conceived as rules that guide the actions of individuals engaged in social interactions. On the other hand, the second approach views institutions as behavioral patterns. In order to have a complete picture of institutions, we need to take both approaches into consideration. Individuals construct mental models to produce expectations about institutions, while institutions make individual expectations relatively compatible. The main purpose (...) of this paper is to develop a general framework within which it is possible to analyze coevolution of individual mental models and institutions. (shrink)

Variation in decision-making about end-of-life care among ethnic groups creates clinical conflicts. In order to understand changes in preferences for end-of-life care among Japanese who immigrate to the United States, we conducted 18 focus groups with 122 participants: 65 English-speaking Japanese Americans, 29 Japanese-speaking Japanese Americans and 28 Japanese living in Japan.Negative feelings toward living in adverse health states and receiving life-sustaining treatment in such states permeated all three groups. Fear of being meiwaku, a physical, psychological or financial caregiving burden (...) on loved ones, was a prominent concern. They preferred to die pokkuri (popping off) before they become end stage or physically frail. All groups preferred group-oriented decision-making with family. Although advance directives were generally accepted, Japanese participants saw written directives as intrusive whereas Japanese Americans viewed them mainly as tools to reduce conflict created by dying person's wishes and a family's kazoku no jo– responsibility to sustain the dying patient. These findings suggest that in the United States Japanese cultural values concerning end-of-life care and decision-making process are largely preserved. (shrink)

Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is ‘diagnostic’. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate (...) whether they had seen the images during the study phase. Surprisingly, performance was better for greyscale than for coloured images, and this difference is due to the higher false alarm rate for both natural and man-made coloured scenes. We hypothesized that this increase in false alarm rate was due to a shift from scrutinizing details of the image to recognition of the gist of the image. A second experiment, utilizing images without a nameable gist, confirmed this hypothesis as participants now performed equally on greyscale and coloured images. In the final experiment we specifically targeted the more detail-based perception and recognition for greyscale images versus the more gist-based perception and recognition for coloured images with a change detection paradigm. The results show that changes to images are detected faster when image-pairs were presented in greyscale than in colour. This counterintuitive result held for both natural and man-made scenes and thus corroborates the shift from more detailed processing of images in greyscale to more gist-based processing of coloured images.

Then there exists a generic extension M [ G ] in which $\kappa =\lambda^+$ and $\kappa$ carries a non-trivial $\kappa$ -complete ideal I which is completive but not $\kappa^+$ -saturated. (shrink)

In this article, we shall show the generalized notions of distributivity of Boolean algebras have essential relations with several axioms and properties of set theory, say the Axiom of Choice, the Axiom of Dependence Choice, the Prime Ideal Theorems, Martin's axioms, Lebesgue measurability and so on.
