Prediction is essential for the efficiency of many cognitive processes; however, this process is not always perfect. Predictive coding theory suggests that the brain generates and updates a prediction to respond to an upcoming event. Although an electrophysiological index of prediction, the stimulus preceding negativity, has been reported, it remains unknown whether the SPN reflects the prediction accuracy, or whether it is associated with the prediction error, which corresponds to a mismatch between a prediction and an actual input. Thus, the (...) present study aimed to investigate this question using electroencephalography. Participants were asked to predict the original pictures from pictures that had undergone different levels of pixelation. The SPN amplitude was affected by the level of pixelation and correlated with the subjective evaluation of the prediction accuracy. Furthermore, late positive components were negatively correlated with SPN. These results suggest that the amplitude of SPN reflects the prediction accuracy; more accurate prediction increases the SPN and reduces the prediction error, resulting in reduced LPC amplitudes.

This paper will address one of the “unsolved” problems that has traditionally been called the “form/content” dualism. Husserl writes in Ideas I: “This remarkable duality and unity of sensory hyle and intentional morphe plays a dominant role in the whole phenomenological sphere (in the whole sphere, namely within the stage of constituting temporality, which can be constantly verified)” (Hua III, 192). To be sure, Husserl has defined the sensory hyle “descriptively” as the really immanent [reell] part of consciousness with differences (...) of color, sound, touch and so on, as well as “functionally” as something that can become an adumbration or an aspect of objects through the animating apprehension of active consciousness. But the constitution of an object in his later analysis is clarified more and more in terms of noematic unification (Holenstein, 93), which obscures the function of hyle in the process of constitution.

Shigeto Tsuru is one of Japan's most respected senior economists. In these lectures, he provides a reappraisal of institutionalism as a school of thought and discusses its relevance for the issues which the economic profession today must tackle. Tsuru reconsiders Marxian political economy as an 'institutionalist school', which provides a context for the following discussion of J. M. Keynes, Joseph Schumpeter and Thorstein Veblen. He goes on to present the four key elements of modern institutionalism - i.e., the open-system (...) character of the economy; the problem of planning; the evolutionary process of modern economics; and the normative character of economics - by way of an examination of three present-day institutionalists, Gunnar Myrdal, John K. Galbraith, and K. William Kapp. Tsuru concludes with an evaluation of modern institutionalism and the future of institutional economics. (shrink)

資本主義が混迷を深めるいま、経済学はどんな役割を果たせるか!社会保障の後退、環境問題、金融「カジノ化」から「市場経済と計画経済」等の理論問題までを、縦横に説き明かす。人生哲学も語る。.

'Glocal Public Philosophy' means a practical philosophy that deals with universal public issues from the particular public world or place where each individual lives and acts. Taking historical changes of the nature of public philosophy, as well as of academic situations from the 19th century onwards into consideration, the author tries to develop this idea in view of contemporary philosophies both in Western countries and in Japan. This book provides, not only new knowledge about modern Japanese public philosophies, but also (...) inspiration for a new role of philosophy for the realization of a more peaceful and just societies.

It is often assumed that the reaction time of a saccade toward visual and/or auditory stimuli reflects the sensitivities of our oculomotor-orienting system to stimulus saliency. Endogenous factors, as well as stimulus-related factors, would also affect the saccadic reaction time. However, it was not clear how these factors interact and to what extent visual and auditory-targeting saccades are accounted for by common mechanisms. The present study examined the effect of, and the interaction between, stimulus saliency and audiovisual spatial congruency on (...) the SRT for visual- and for auditory-target conditions. We also analyzed pre-target pupil size to examine the relationship between saccade preparation and pupil size. Pupil size is considered to reflect arousal states coupling with locus-coeruleus activity during a cognitive task. The main findings were that the pattern of the examined effects on the SRT varied between visual- and auditory-auditory target conditions, the effect of stimulus saliency was significant for the visual-target condition, but not significant for the auditory-target condition, Pupil velocity, not absolute pupil size, was sensitive to task set, and there was a significant correlation between the pre-saccade absolute pupil size and the SRTs for the visual-target condition but not for the auditory-target condition. The discrepancy between target modalities for the effect of pupil velocity and between the absolute pupil size and pupil velocity for the correlation with SRT may imply that the pupil effect for the visual-target condition was caused by a modality-specific link between pupil size modulation and the SC rather than by the LC-NE system. These results support the idea that different threshold mechanisms in the SC may be involved in the initiation of saccades toward visual and auditory targets. (shrink)

Understanding whether the long and elaborate songs of male gibbons have syntax and hierarchical structures is an interesting question in the evolution of language, because gibbons are near humans in the phylogenetic tree and a hierarchically organized syntax is considered to be a basic component of human language. We conducted field research at Danum Valley Conservation Area in northern Borneo to test the hypothesis that gibbon songs have syntax and chunks. We followed one Mueller’s gibbon group for 1 week in (...) the dry and rainy seasons every year from 2001 to 2009, collecting vocal and behavioral data. Results show that songs emitted by the studied male gibbon were governed by combinatory rules. Some context-dependent songs had different combinatory rules, although they overlapped with the songs whose contexts were uncertain. The male Mueller’s songs had characteristics that suggest existence of chunk structure. These results provided an important perspective in the study of language origin. (shrink)

Mueller's gibbons ( Hylobates muelleri ) sing both sex-specific and duet songs. These songs are thought to be involved in territory maintenance, as well as the maintenance of pair or family bonds. However, few observational studies have examined how gibbons interact with their neighbors through song in the wild. We have been conducting field observations of wild gibbon groups in northeast Borneo since 2001. In the Borneo Rainforest Lodge (BRL) and Danum Valley Field Center (DVFC) at the Danum Valley Conservation (...) Area (DVCA), we observed seven episodes of alternating songs between males. Here, we describe the process of song exchange between males. During male interactions, song bouts rarely overlapped and were alternately emitted. Several studies have reported antiphonal vocalizations in New World and Old World primate species, but rarely in apes. Our observations of antiphonal songs in gibbons indicate that gibbons not only unilaterally advertise information, but also interactively communicate with neighbors and family members through songs. Since gibbons are phylogenetically similar to humans, and turn-taking has an important role in human conversation, our research on gibbon communication may provide insight into the evolution of human language.

By Katrin Amell. Studia Missionalia Upsaliensia LXX. Uppsala: The Swedish Institute of Missionary Research, 1998. 245 pp. ISBN 91-85424-50-1. The Ground (...) We Share: Everyday Practice, Buddhist and Christian. By Robert Aitken and David Steindl-Rast. Edited by Nelson Foster. Boston and London: Shambala, 1996. xviii + 233 pp. ISBN 1-57062-219-1. $15.00. Here are two meritorious and well-produced works devoted to the dialogue between Buddhism and Christianity. They also have in common a certain desultoriness which left me reflecting on the limits of the rhetoric of 'dialogue.' Having taken over from 'liberation' as a theological buzzword, 'dialogue' seems by now to have exhausted its usefulness. William James remarked that everything genuine will somewhere become a sham. Lip service to a vague ideal of dialogue becomes a substitute for the unmet challenge of Buddhist-Christian thought, and the less the dialogue is practiced the more its importance is verbally celebrated. The retention of the word 'dialogue' may even serve to keep the religious other at a comfortable distance: it is more reassuring to say, "Of course we are in dialogue with the Buddhists" than to say "We are facing up to the challenge Buddhist thought poses to Christian theology," for in the former statement the Buddhists remain conveniently located others, sitting across the table, rather than a troublesome, potentially subversive presence within our own intellectual world. [End Page 315]In their submission to the recent Roman synod of Asian bishops, the Japanese bishops made much of their commitment to interreligious dialogue, and this was acclaimed with enthusiasm. But the impression left by Karin Amell's book (a doctoral thesis in missiology) is that not very much is going on in this area in Japan, the country seen as "the promised land of dialogue" after Vatican II (p. 119). "One has the impression that it is an activity for a few specialists" (p. 145), leaving the ordinary faithful largely untouched. Amell apparently does not read Japanese, so there may be much that she has missed, yet for my part I can think of nothing to add to the factual content of her account. For the spiritual side of the encounter she focuses on three Japanese pioneers, now in their seventies (pp. 150-191): Kadowaki Kakichi, SJ, Okumura Ichiro, OCD, and Oshida Shigeto, OP. To what extent these men have succeeded in creating a widespread Catholic Zen culture remains unclear, but Amell believes the "dialogue of religious experience" is the most widespread form of Buddhist-Catholic interaction in Japan (p. 146). As to scholarship, which is not Amell's direct concern, one has the impression that everyone is too busy with church and university affairs to devote their time to this. The scholarly labors of Heinrich Dumoulin, for example, have not been continued by anyone else. Despite the work of a powerful Catholic foundation, the Nanzan Institute for Religion and Culture (p. 141), Buddhism does not seem to excite Catholic intellectuals in Japan. Japanese Catholics are a small community, numbering about half a million. But given the high number of theologians, clergy and religious (p. 137), one would expect a more intensive interaction with local religious traditions. Instead the focus of theological interest remains fixed on Western sources. It is not so much that the situation of a small church in the midst of secularized-polytheistic-Buddhist Japan fails to give food for thought as that people seem afraid to think out its implications. Those engaged in contemplative sharing with Buddhists seem to avoid intellectual issues. Amell is uneasy with the insistence on intuition and the latent anti-intellectualism she finds in the intermonastic dialogue (discussed in the first half... (shrink)
