Brain-computer interface (BCI) systems were developed so that people can control computers or machines through their brain activity without moving their limbs. The P300 speller is one of the BCI applications used most commonly, as is very simple and reliable and can achieve satisfactory performance. However, like other BCIs, the P300 speller still has room for improvements in terms of its practical use, for example, selecting the best compromise between spelling accuracy and information transfer rate (ITR; speed) so that the (...) P300 speller can maintain high accuracy while increasing spelling speed. Therefore, seeking correlates of, and predicting, the P300 speller’s performance is necessary to understand and improve the technique. In this work, we investigated the correlations between rapid serial visual presentation (RSVP) task features and the P300 speller’s performance. Fifty-five subjects participated in the RSVP and conventional matrix P300 speller tasks and RSVP behavioral and electroencephalography (EEG) features were compared in the P300’s speller performance. We found that several of the RSVP’s event-related potential (ERP) and behavioral features were correlated with the P300 speller’s offline binary classification accuracy. Using these features, we propose a simple multi-feature performance predictor ( r = 0.53, p = 0.0001) that outperforms any single feature performance predictor, including that of the conventional RSVP T1% predictor ( r = 0.28, p = 0.06). This result demonstrates that selective multi-features can predict BCI performance better than a single feature alone. (shrink)

There are two main paradigms for brain-related science, with different implications for brain-focused intervention or advancement. The paradigm of homeostasis (“stability through constancy,” Walter Cannon), originating from laboratory-based experimental physiology pioneered by Claude Bernard, shows that living systems tend to maintain system functionality in the direction of constancy (or similitude). The aim of physiology is elucidate the factors that maintain homeostasis, and therapeutics aim to correct abnormal factor functions. The homeostasis paradigm does not formally recognize influences outside its controlled experimental (...) frames and it is variable in its modelling of neural contributions. The paradigm of allostatic orchestration (PAO) extends the principle of allostasis (“stability through change”) as originally put forth by Peter Sterling. The PAO originates from an evolutionary perspective and recognizes that biological set points change in anticipation of changing environments. The brain is the organ of central command, orchestrating cross-system operations to support optimal behavior at the level of the whole organism. Alternative views of blood pressure regulation and posttraumatic stress disorder illustrate differences between the paradigms. For the PAO, complexities of top-down neural effects and environmental context are foundational (not to be “factored out”), and anticipatory regulation is the principle of their interface. The allostatic state represents the integrated totality of brain-body interactions. Health itself is an allostatic state of optimal anticipatory oscillation, hypothesized to relate to the state of criticality, a mathematical point of poise between phases, on the border between order and disorder (or the “edge of chaos”). Diseases are allostatic states of impaired anticipatory oscillations, demonstrated as rigidifications of set points across the brain and body (disease comorbidity). Conciliation of the paradigms is possible, with “reactive homeostasis” resolved as an illusion stemming from anticipation of environmental monotony. Considerations are presented with respect to implications of the two paradigms for brain-focused intervention or advancement; the hypothesis that the state of criticality is a vehicle for evolutionary processes; concordance with a philosophy of freedom based on ethical individualism as well as self-creativity, non-obsolescence, empowerment, and citizenship; and concluding reflections on the science and ethics of the placebo, and the potential for virtuous cycles of brain-Anthropocene interactions.

We are typically near-future biased, prioritising our present and near-future interests over our own distant-future interests. This bias can be directed at others as well, prioritising their present and near-future interests over their distant-future interests. I here argue that, given these biases, and given a plausible limit on the extent to which we can permissibly prioritise our present interests over the present interests of strangers, we are morally required to prioritise the present interests of strangers over our distant-future interests. I (...) also argue that a similar conclusion holds even if we are near biased only towards ourselves, and regardless of whether this bias is rational. And I show that my conclusions have interesting implications for the ethics of charitable giving, because they generate moral pressure to donate to charity those funds that would otherwise have gone into our long-term savings.

This study analyses the types and frequencies of ethical dilemmas and the rationale of ethical decision making in student nurses; it also evaluates their decision making. One hundred senior student nurses who were enrolled in a two-credit course in nursing ethics were asked to provide an informal description of a dilemma that they had experienced during their clinical practice. The results were as follows. The ethical dilemmas identified fell into four categories and were of 27 types. Those most frequently experienced (...) were ‘family giving up on a patient because he or she could not be cured’, and ‘not telling the truth to the patient’. The Korean Nurses’ Code of Ethics was applied, in particular the preamble, and the third, fourth, seventh and tenth clauses. The most common rule of ethics and principle applied in these nurses’ ethical decision making were veracity and nonmaleficence. With regard to the moral reasoning process, the primary concern was the welfare of the patients. These students were equipped with the ability to exercise critical and reflective thought when they experienced ethical dilemmas. (shrink)

The technical term “ tarka ” in the Nyāya tradition is the object of the present investigation. Diverse texts including Buddhist ones exhibit a negative estimation of activities using tarka . In contrast, more often than not, later treatises dealing with logico-epistemic problems, especially certain Naiyāyika works, identify the methodological peculiarity of Nyāya with tarka . Such an ambivalent attitude toward tarka can be understood in a coherent way if the essential features of tarka that gave rise to it can (...) be grasped. Starting from the Nyāyasūtra 1.1.40 and the explanation given in the Nyāyabhāṣya on it, the present researcher sorted out three characteristic features of tarka in the early Nyāya tradition. These three features focus on the main feature of tarka : namely, reflective analysis without requiring further factual information on the object of investigation. Based on this, the present researcher critically reviewed what promoted an understanding of tarka as a reductio ad absurdum argument or an a priori reasoning. Furthermore, certain passages from the Nyāyamañjarī , Nyāyakalikā , and Tarkasaṅgraha were examined to demonstrate that the present researcher’s interpretative understanding of tarka was adequate for explaining the usage of this term in a broad sense, with positive connotations.

The main purpose of this study was to validate a scale to examine the moral sensitivity of Korean nurses. A pre-existing scale, the Moral Sensitivity Questionnaire (MSQ), developed by Lützén, was used after deletion of three items. The reliability and validity of the scale were examined by using Cronbach’s alpha and factor analysis, respectively. According to the results, reliability of the scale was adequate but its construct validity was not fully supported. Through discussion on evidence of validity, five subconstructs emerged. (...) In particular, unlike the factor structure of the MSQ, two subconstructs, patient-oriented care and professional responsibility, were newly extracted. It was assumed that the other three MSQ subconstructs, conflict, meaning and benevolence (expressed as nurses being ethically good), would not be sensitive to cultural background. Given these findings, interpretations about the meaning of moral sensitivity of Korean nurses are discussed. (shrink)

This article focuses on a psychological phenomenon discussed by the early Confucian: yuan 怨, which is often translated as “resentment”, “grievance”, “lament”, or “complaint”. I attempt to use the early Confucian discussions of yuan to shed light on an aspect of human psychology, namely, when one laments about certain conditions that obtain in such a way that she sees as beyond her control and negatively affects her. This is an unusual reactive attitude because one who has yuan takes the “passive (...) stance.” This paper has four main sections: the first section makes textual observations of “yuan” in the early Confucian texts; the second section proposes a Confucian-inspired account of yuan and highlights the psychological state in which one who has yuan sees oneself as object; the third section discusses the problematic dimensions of yuan; the final section discusses the negative implications of the passive stance with respect to contemporary concerns: vulnerability, moral repair, and self-respect.

Purpose: The purpose of this study was to verify the long-term effect of adverse childhood experiences, school disengagement, and the reasons for leaving school on adolescent delinquency while adjusting for sex.Methods: Data were collected from 663 teenagers [male 368, female 295; mean age = 16.81 ; age range = 13–19 years] through a Longitudinal Survey and Support Plan for Dropouts.Results: Multivariate latent growth modeling demonstrated that ACEs and school disengagement are positively associated with delinquency and the mediating effect of school (...) disengagement on association between ACEs and delinquency was verified. Teenagers who quit school for personal reasons reported fewer instances of delinquent behavior than adolescents who left because of school reasons.Conclusion: This study suggests that researchers and teachers need to consider ACEs and school disengagement as a warning index for delinquency with school dropout. In addition, the reason for leaving school should be considered to clarify the effect of school dropout on delinquency in adolescents who dropout. (shrink)

Most people have the intuition that, when we can save the lives of either a few people in one group or many people in another group, and all other things are equal, we ought to save the group with the most people. However, several philosophers have argued against this intuition, most famously John Taurek, in his article ‘Should the Numbers Count?’ They argue that there is no moral obligation to save the greater number, and that we are permitted to save (...) either the many or the few. I argue in this article that, even if we are almost completely persuaded by these ‘numbers sceptics’, we ought not to just save the few. If the choice is simply between saving the many or the few, we ought to save the many. (shrink)

In this paper, we devise a network that consists of argumentation schemes and critical questions that participants in debates can use to easily construct arguments that attack or support former arguments. As a prototype, we build a potential network of argumentation schemes and critical questions with a practical reasoning scheme at its center. The usefulness of a NASCQ in constructing and reconstructing complex arguments and in formal argumentation is also explored along with argumentation more broadly.

‘Tarka’ is a technical term that occupies a significant position in the logico-epistemological traditions in India. In this paper, it is attempted to expound the exact meaning of the term, in particular in the early Nyaya tradition, on the basis of the explanations found in the Nyayabhasya. The view that the essential feature of tarka consists in the differentiating approach (vibhaga) to the matter on discourse is substantiated, and with it a possible explanation is given for the well-known ambivalent valuations (...) that tarka was often loaded with a negative connotation on the one hand and, was considered as the positive characteristic feature of the Naiyayika approach to epistemological problems on the other. In the case of tarka, the general applicability and the impression of logically exhaustive access to any given problem was combined with the danger of misuse of the reason without any quasi-formal deficiency. It is hoped that my suggestion to characterize tarka as the differentiating approach to the given matter without any factual information may give a plausible explanation for the double-pole character of tarka in the history of Indian philosophy.

Storytelling is getting increasing attention as one of the effective strategies for revitalizing the local festivals and even regional economies. Yet, the mechanisms through how storytelling helps the success of local festivals are still relatively less known. Using the data from 322 individuals who participated in local festivals using storytelling, our results showed that local festival storytelling is positively related to tourists’ revisit intention. Furthermore, the positive relationship between local festival storytelling and tourists’ revisit intention was serially mediated by authenticity (...) and positive emotion. Theoretical and practical implications are discussed. (shrink)

The current study aims to separate conscious and unconscious behaviors by employing both online and offline measures while the participants were consciously performing a task. Using an eye-movement tracking paradigm, we observed participants’ response patterns for distinguishing within-word-boundary and across-word-boundary reverse errors while reading Chinese sentences . The results showed that when the participants consciously detected errors, their gaze time for target words associated with across-word-boundary reverse errors was significantly longer than that for targets words associated with within-word-boundary reverse errors. (...) Surprisingly, the same gaze time pattern was found even when the readers were not consciously aware of the reverse errors. The results were statistically robust, providing converging evidence for the feasibility of our experimental paradigm in decoupling offline behaviors and the online, automatic, and unconscious aspects of cognitive processing in reading.

This paper argues that yu 欲 (desire), in Xunzi’s view, cannot by itself motivate action. Such a clarification will also bear on our understanding of the relation between xin 心 (the heart/mind) and yu in the Xunzi. This paper is divided into three main sections. The first section seeks to explicate the common assumption that yu can be an independent source of motivation. In the second section, I will conduct textual analysis that challenges such an assumption and argues that only (...) xin can by itself motivate action. In the third section, I explain that the issue of whether yu can conflict with xin is not applicable in Xunzi’s thought and extrapolate the implications that xin is always activated and that xin has natural inclination to pursue the objects of yu. For these reasons, the source of moral failure lies in xin being active in certain problematic ways. (shrink)

It is often necessary and reasonable to justify preferences before reasoning from them. Moreover, justifying a preference ordering is reduced to justifying the criterion that produces the ordering. This paper builds on the well-known ASPIC+ formalism to develop a model that integrates justifying qualitative preferences with reasoning from the justified preferences. We first introduce a notion of preference criterion in order to model the way in which preferences are justified by an argumentation framework. We also adapt the notion of argumentation (...) theory to build a sequence of argumentation frameworks, in which an argumentation framework justifies preferences that are to underlie the next framework. That is, in our formalism, preferences become not only an input of an argumentation framework, but also an output of it. This kind of input-output process can be applied in the further steps of argumentation. We also explore some interesting properties of our formalism. (shrink)

This study raises the question whether it is possible, in Xunzi’s 荀子 view, for someone who has gone through moral transformation to backslide. I consider three possible interpretations. On the first interpretation, one’s dispositions are transformed by environmental forces. Backsliding is possible and likely. I rule out this interpretation because it is inconsistent with other aspects of Xunzi’s thought. On the second interpretation, one’s kind-determining constitution is transformed from a neutral constitution to a moral constitution. Backsliding is not possible because (...) one has acquired a moral constitution that is insusceptible to bad environmental influences. On the third interpretation, to be transformed is to have accumulated significantly more moral knowledge than ordinary untransformed people. Backsliding is possible but unlikely. I will then explain why it is difficult to adjudicate between the second and third interpretations and suggest further issues in Xunzi’s thought that need to be investigated. (shrink)

The aim of this paper is to critically review the traditional typology of argument macrostructures, particularly, the dichotomy between linked and convergent structure. We have found an argument structure that does not fall under one of those five traditional categories: basic, serial, divergent, linked and convergent. We show that the new argument structure, which we call the recursive structure, is not rare-earth, but ubiquitous in real argumentation. Then, we propose and justify a new approach to diagramming arguments of the structure. (...) The new argument structure is really new because arguments of the new structure are analyzed and evaluated differently from those of the other structures, especially from hybrid arguments considered in the literature. In light of the new argument structure, we present a hypothesis why assumptions and exceptions of a defeasible argument play different roles in dialectical settings. (shrink)

Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese learning English /r/-/l/ (...) categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players’ responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5 h across 5 days exhibited improvements in /r/-/l/ perception on par with 2–4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.
