Synchronized movements with external periodic rhythms, such as dancing to a beat, are commonly observed in daily life. Although it has been well established that some vocal learning species (including parrots and humans) spontaneously develop this ability, it has only recently been shown that monkeys are also capable of predictive and tempo-flexible synchronization to periodic stimuli. In our previous study, monkeys were trained to make predictive saccades for alternately presented visual stimuli at fixed stimulus onset asynchronies (SOAs) to obtain a (...) liquid reward. The monkeys generalized predictive synchronization to novel SOAs in the middle of trained range, suggesting a capacity for tempo-flexible synchronization. However, it is possible that when encountering a novel tempo, the monkeys might sample learned saccade sequences from those for the short and long SOAs so that the mean saccade interval matched the untrained SOA. To eliminate this possibility, in the current study we tested monkeys on novel SOAs outside the trained range. Animals were trained to generate synchronized eye movements for 600 and 900-ms SOAs for a few weeks, and then were tested for longer SOAs. The accuracy and precision of predictive saccades for one untrained SOA (1200 ms) were comparable to those for the trained conditions. On the other hand, the variance of predictive saccade latency and the proportion of reactive saccades increased significantly in the longer SOA conditions (1800 and 2400 ms), indicating that temporal prediction of periodic stimuli was difficult in this range, similar to previous results on synchronized tapping in humans. Our results suggest that monkeys might share similar synchronization mechanisms with humans, which can be subject to physiological examination in future studies. (shrink)

In April 1991, a general meeting of the Japanese Medical Conference was held in Kyoto and attracted 32,500 participants, the largest number ever. The theme of the meeting was “Medicine and Health Care in Transition,” and the program Included panel discussions on “How to Promote the Quality of Health Care” and “How Terminal Care Should Be Provided” and symposia on “Diagnosis of Brain Death and Its Problems,” “The Propriety of Organ Transplantation,” and “Brain Death and Organ Transplantation.” These titles reveal (...) not only how medical professionals in Japan perceive the present situatior healthcare but also the Issues that most concern them.

James Mill's views on peace and war have yet to be examined in detail. Only a few scholars have paid any attention to this aspect of his thought. Edmund Silberner was the first to give any extensive account of Mill's opposition to war and his proposals for universal peace, but chiefly from an economic point of view. He rightly pointed out that Mill's opposition to war was grounded mainly on his belief that war always obstructs the progress of national wealth, (...) and also that Mill regarded the acquisition and possession of colonies as one of the major causes of war. F. H. Kinsley summed up the leading ideas of Mill's article on the ‘Law of Nations’, but only to show how far Bentham influenced Mill's thinking in this specific area. (shrink)

0 From Sansui to Keshiki My subject here is the nature of landscape. The word “landscape” is to be understood in what follows in the aesthetic sense: I wish to clarify what we experience in landscape as a typical scene of natural beauty. For most people, the nature of this experience may be so transparent that its analysis is superfluous. I don’t, however, find the matter so straightforward. The fact that “a landscape” can also signify a landscape painting would seem (...) to indicate that landscap... (shrink)

Examining the interconnections between genes and culture is crucial for a more complete understanding of psychological processes. Genetic predispositions may predict different outcomes depending on one's cultural context, and culture may predict different outcomes depending on genetic predispositions - that is, genes and culture interact. Less is understood, however, about how genes and culture interact, or the psychological mechanisms through which gene–culture interactions occur. In this Element, Joni Y. Sasaki and Heewon Kwon review key findings and theories in gene–culture (...) interaction research. They then go on to discuss current issues and future directions in gene–culture research that may illuminate the path toward an explanatory framework. (shrink)

This paper describes the situation of philosophy in Japan with respect to the question of internationalism. For more than a hundred years, Japan took Western culture as its model and European philosophy as the authentic philosophy. This tendency was paradoxically strengthened by the post‐war humanism. It gave us Japanese philosophers a clear discipline to work in but cut us off from our own native culture, history, and philosophical traditions. In wishing to recover this loss, I argue that it is necessary (...) to distinguish between two forms of internationalism: humanistic and merely fashionable. The latter in fact derives from domestic reasons. (shrink)

In this paper, we discuss semantical properties of the logic $\textbf{GL}$ of provability. The logic $\textbf{GL}$ is a normal modal logic which is axiomatized by the the Löb formula $\Box (\Box p\supset p)\supset \Box p$, but it is known that $\textbf{GL}$ can also be axiomatized by an axiom $\Box p\supset \Box \Box p$ and an $\omega$ -rule $(\Diamond ^{*})$ which takes countably many premises $\phi \supset \Diamond ^{n}\top$ $(n\in \omega )$ and returns a conclusion \(\phi \supset (...) \bot \). We show that the class of transitive Kripke frames which validates $(\Diamond ^{*})$ and the class of transitive Kripke frames which strongly validates $(\Diamond ^{*})$ are equal, and that the following three classes of transitive Kripke frames, the class which validates $(\Diamond ^{*})$, the class which weakly validates $(\Diamond ^{*})$, and the class which is defined by the Löb formula, are mutually different, while all of them characterize $\textbf{GL}$. This gives an example of a proof system _P_ and a class _C_ of Kripke frames such that _P_ is sound and complete with respect to _C_ but the soundness cannot be proved by simple induction on the height of the derivations in _P_. We also show Kripke completeness of the proof system with $(\Diamond ^{*})$ in an algebraic manner. As a corollary, we show that the class of modal algebras which is defined by equations $\Box x\le \Box \Box x$ and $\bigwedge _{n\in \omega }\Diamond ^{n}1=0$ is not a variety. (shrink)

Using anthropological theory, this paper examines human–android interactions (HAI) as an emerging aspect of android science. These interactions are described in terms of adaptive learning (which is largely subconscious). This article is based on the observations reported and supplementary data from two studies that took place in Japan with a teleoperated android robot called Telenoid in the socialization of school children and older adults. We argue that interacting with androids brings about a special context, an interval, and a space/time for (...) reflection and imagination that was not there before. During the interaction something happens. There is adaptive learning and as a result, both children and older adults accepted Telenoid, and the children and older adults accepted each other. Using frames of play and ritual, we make sense and ‘capture’ moments of adaptive learning, and the feedback that elicits a social response from all study participants that results in self-efficacy and socialization. While “ritual” refers to the application of what has been learned and “play” means that there are no obvious consequences of what has been learned. This analysis illuminates new understanding about the uncanny valley, cultural robotics and the therapeutic potential of HAI. This has implications for the acceptance of androids in ‘socialized roles’ and gives us insight into the subconscious adaptive learning processes that must take place within humans to accept androids into our society. This approach aims to provides a clearer conceptual basis and vocabulary for further research of android and humanoid development. (shrink)

We introduce a Gentzen style formulation of Basic Propositional Calculus(BPC), the logic that is interpreted in Kripke models similarly tointuitionistic logic except that the accessibility relation of eachmodel is not necessarily reflexive. The formulation is presented as adual-context style system, in which the left hand side of a sequent isdivided into two parts. Giving an interpretation of the sequents inKripke models, we show the soundness and completeness of the system withrespect to the class of Kripke models. The cut-elimination theorem isproved (...) in a syntactic way by modifying Gentzen's method. Thisdual-context style system exemplifies the effectiveness of dual-contextformulation in formalizing various non-classical logics. (shrink)

Objective:This study aimed to investigate the effect of robot-assisted gait training therapy combined with non-invasive brain stimulation on lower limb function in patients with stroke and spinal cord injury.Data sourcesPubMed, Cochrane Central Register of Controlled Trials, Ovid MEDLINE, and Web of Science were searched.Study selectionRandomized controlled trials published as of 3 March 2021. RCTs evaluating RAGT combined with NIBS, such as transcranial direct current stimulation and repetitive transcranial magnetic stimulation, for lower limb function and activities in patients with stroke and (...) SCI were included.Data extractionTwo reviewers independently screened the records, extracted the data, and assessed the risk of bias.Data synthesisA meta-analysis of five studies and risk of bias were conducted. Pooled estimates demonstrated that RAGT combined with NIBS significantly improved lower limb function [standardized mean difference = 0.52; 95% confidence interval = 0.06–0.99] but not lower limb activities. Subgroup analyses also failed to find a greater improvement in lower limb function of RAGT with tDCS compared to sham stimulation. No significant differences between participant characteristics or types of NIBS were observed.ConclusionThis meta-analysis demonstrated that RAGT therapy in combination with NIBS was effective in patients with stroke and SCI. However, a greater improvement in lower limb function and activities were not observed using RAGT with tDCS compared to sham stimulation. (shrink)

Here, we provide a detailed description of the mutual relation of formulas with finite propositional variables p1, …, pm in modal logic S4. Our description contains more information on S4 than those given in Shehtman (1978) and Moss (2007); however, Shehtman (1978) also treated Grzegorczyk logic and Moss (2007) treated many other normal modal logics. Specifically, we construct normal forms, which behave like the principal conjunctive normal forms in the classical propositional logic. The results include finite and effective methods to (...) find a normal form equivalent to a given formula A by clarifying the behavior of connectives and giving a finite method to list all exact models.

Are mechanisms for social attention influenced by culture? Evidence that social attention is triggered automatically by bottom-up gaze cues and is uninfluenced by top-down verbal instructions may suggest it operates in the same way everywhere. Yet considerations from evolutionary and cultural psychology suggest that specific aspects of one's cultural background may have consequence for the way mechanisms for social attention develop and operate. In more interdependent cultures, the scope of social attention may be broader, focusing on more individuals and relations (...) between those individuals. We administered a multi-gaze cueing task requiring participants to fixate a foreground face flanked by background faces and measured shifts in attention using eye tracking. For European Americans, gaze cueing did not depend on the direction of background gaze cues, suggesting foreground gaze alone drives automatic attention shifting; for East Asians, cueing patterns differed depending on whether the foreground cue matched or mismatched background cues, suggesting foreground and background gaze information were integrated. These results demonstrate that cultural background influences the social attention system by shifting it into a narrow or broad mode of operation and, importantly, provides evidence challenging the assumption that mechanisms underlying automatic social attention are necessarily rigid and impenetrable to culture.
