Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

Mark Coeckelbergh (Int J Soc Robot 1:217–221, 2009) argues that robot ethics should investigate what interaction with robots can do to humans rather than focusing on the robot’s moral status. We should ask what robots do to our sociality and whether human–robot interaction can contribute to the human good and human flourishing. This paper extends Coeckelbergh’s call and investigate what it means to live with disembodied AI-powered agents. We address the following question: Can the human–AI interaction contribute to our moral (...) development? We present an empirically informed philosophical analysis of how the AI personal assistant Siri changes its users’ way of life, based on the responses obtained from 20 semi-directive individual interviews with Siri users. We identify changes in the users’ social interaction associated with the adoption of Siri. These changes include: (1) the indirect effect of reducing opportunities of human interaction, (2) the second-order effect of diminished expectations toward each other in a community, and (3) the acquired preference to obtain hassle-free interaction with Siri over human interaction. We examine them in relation to concerns that are voiced in the current debates over the rise of AI, namely the suspicion that humans could become overly reliant on AI (Danaher 2019) and the worry that social AI could impede on moral development (Fröding and Peterson, Ethics Inf Technol 23:207–214, 2012; Li, Ethics Inf Technol 23:543–550, 2021). We analyze the ethical costs that come from these changes in light of virtue ethics and address potential objections along the way. We end by offering directions for thinking about how to live with AI personal assistant while preserving favorable conditions for moral development. (shrink)

Rhythm is key to language acquisition. Across languages, rhythmic features highlight fundamental linguistic elements of the sound stream and structural relations among them. A sensitivity to rhythmic features, which begins in utero, is evident at birth. What is less clear is whether rhythm supports infants' earliest links between language and cognition. Prior evidence has documented that for infants as young as 3 and 4 months, listening to their native language supports the core cognitive capacity of object categorization. This precocious link (...) is initially part of a broader template: listening to a non-native language from the same rhythmic class as and to vocalizations of non-human primates provide English-acquiring infants the same cognitive advantage as does listening to their native language. Here, we implement a machine-learning approach to ask whether there are acoustic properties, available on the surface of these vocalizations, that permit infants' to identify which vocalizations are candidate links to cognition. We provided the model with a robust sample of vocalizations that, from the vantage point of English-acquiring 4-month-olds, either support object categorization or fail to do so. We assess whether supervised ML classification models can distinguish those vocalizations that support cognition from those that do not, and which class of acoustic features best support that classification. Our analysis reveals that principal components derived from rhythm-relevant acoustic features were among the most robust in supporting the classification. Classifications performed using temporal envelope components were also robust. These new findings provide in principle evidence that infants' earliest links between vocalizations and cognition may be subserved by their perceptual sensitivity to rhythmic and spectral elements available on the surface of these vocalizations, and that these may guide infants' identification of candidate links to cognition.

ABSTRACTDifficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive–behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire, a self-report measure of fear inhibition abilities. We assess the FIQ’s factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants (...) from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whi... (shrink)

The concept of rectifying names [cheng-ming] is a familiar one in the Confucian Analects. It occupies an important, if not central, position in the political philosophy of Confucius. Since, according to Confucius, the rectification of names is the basis of the establishment of social harmony and political order, one might suspect that later political theories of Confucian-ists should be traced back to the Confucian doctrine of rectifying names. It need not be added that the theory of rectifying names, as developed (...) by Hsün Tzu in the third century B. C., served the double purpose of strengthening his political doctrine of government on the one hand and repudiating doctrines of names on the other. (shrink)

This paper compares some key concepts from Buddhism with ideas from different traditions of systems thinking. There appear to be many similarities, suggesting that there is significant potential for dialogue and mutual learning. The similarities also indicate that it may be possible to develop a Buddhist systems methodology to help guide exploration and change within Buddhist organisations.

Three experiments examined repetition priming for meaningful environmental sounds in a sound stem identification paradigm using brief sound cues. Prior encoding of target sounds together with their associated names facilitated subsequent identification of sound stems relative to nonstudied controls. In contrast, prior exposure to names alone in the absence of the environmental sounds did not prime subsequent sound stem identification performance at all . Explicit and implicit memory were dissociated such that sound stem cued recall was higher following semantic than (...) nonsemantic encoding, whereas sound priming was insensitive to manipulations of depth encoding . These results extend the findings of long-term repetition priming into the auditory nonverbal domain and suggest that priming for environmental sounds is mediated primarily by perceptual processes.

It has been over a decade and half since Christof Koch and the late Francis Crick first advocated the now popular NCC project (Crick and Koch, 1990), in which one tries to find the neural correlate of consciousness (NCC) for perceptual processes. In his chapter in this book Chris Frith provides a splendid review of how neuroimaging has contributed greatly to this project. For the sake of contrast, this chapter takes a more critical stance on what we have actually learned. (...) Many authors have written on whether looking for the neural correlates would eventually lead to an explanatory theory of consciousness, while the proponents defend that focusing on correlates is a strategically sensible first step, given the complexity of the problem (Crick and Koch, 1998;Crick and Koch, 2003). My point here is not to argue whether studying the NCC is useful, but rather, to question whether we are really studying the NCC at all. I argue that in hoping to sidestep the difficult conceptual issues, we have sometimes also missed the phenomenon of perceptual consciousness itself. (shrink)

This paper proposes a novel account of why intertemporal decisions tend to display impatience: People pay more attention to the opportunity costs of choosing larger, later rewards than to the opportunity costs of choosing smaller, sooner ones. Eight studies show that when the opportunity costs of choosing smaller, sooner rewards are subtly highlighted, people become more patient, whereas highlighting the opportunity costs of choosing larger, later rewards has no effect. This pattern is robust to variations in the choice task, to (...) the participant population, and is observed for both incentivized and hypothetical choices. We argue that people are naturally aware of the opportunity costs associated with delayed rewards, but pay less attention to those associated with taking smaller, sooner ones. We conclude by discussing implications for theory and policy. (shrink)

While environmental claims are increasingly used by companies to appeal consumers, they also attract greater scrutiny from independent parties interested in consumer protection. Consumers are now able to compare corporate environmental claims against external, often disconfirming, information to form their brand attitudes and purchase intentions. What remains unclear is how the level of information specificity of both the environmental claims and external disconfirming information interact to influence consumer reactions. Two experiments address this gap in the CSR communication literature. When specific (...) claims are countered by specific external information, consumers report more negative brand attitudes and lower purchase intentions. The effect is serially mediated by skepticism toward the claims and lack of corporate credibility. We conclude by discussing strategies that firms can utilize to avoid information dilution and ensure that external disconfirming information percolates to consumers as specific. (shrink)

The effectiveness of complaint handling and service recovery policies in customer retention has been the focus of both scholars and service organizations. In the past decade, Justice Theory has provided the basis of the dominant theoretical framework for complaint management and service recovery. However, it does not explicitly address unfair trade practices, which constitute an ethical issue. Favorable outcomes in complaint handling may not be able to restore the reputation of a company and the potential harm perceived by consumers. Using (...) face-to-face interviews, this study applies Fairness Theory to explore the psychological responses of consumers in the post-complaint phase, particularly in ethical judgment. The findings suggest that an unfavorable outcome in the post-complaint stage leads to counterfactual thinking by the consumer about the consumer's state of well-being. The complaint must be due to the discretionary actions of the service provider whose accountability is assessed. Those harmful actions are then judged against an ethical standard. Explanations can reduce blame, and their effectiveness is moderated by outcome favorability but not ethical judgment. Favorable outcome, captured by "Would Perception," has only limited influence on Perceived Potential Harm (PPH), which is an important determinant of ethical judgment. This study makes both theoretical and practical contributions. It is the first study to validate Fairness Theory empirically and apply it to complaint handling as a complement of Justice Theory in the information and communication technology (ICT) service context. The study indicates that customers may condemn a service provider because of PPH even though the outcome is favorable. Unfair trade practices are what make customers hate ICT service providers.

We extend research on the effects of local audit office characteristics on audit quality by investigating whether audit offices in highly religious U.S. Metropolitan Statistical Areas exhibit going concern decisions that reflect heightened professional skepticism relative to audit offices in less religious MSAs. Prior research links religiosity to risk aversion and ethical development and suggests audit practice offices in more religious MSAs are more likely to issue going concern opinions because they will assess the effects of mitigating factors in a (...) more skeptical manner. Our results indicate that audit practice offices located in highly religious MSAs are more likely to issue going concern audit opinions, consistent with a more skeptical assessment of mitigating factors. Additional tests provide direct evidence consistent with the argument that these audit offices are more risk averse in issuing going concern opinions. Our findings are relevant to auditors, audit clients, researchers, and regulators. (shrink)

A record of the words and teachings of Confucius, _The Analects_ is considered the most reliable expression of Confucian thought. However, the original meaning of Confucius's teachings have been filtered and interpreted by the commentaries of Confucianists of later ages, particularly the Neo-Confucianists of the Song dynasty, not altogether without distortion.In this monumental translation by Professor D. C. Lau, an attempt has been made to interpret the sayings as they stand. The corpus of the sayings is taken as an organic (...) whole and the final test of the interpretation rests on the internal consistency it exhibits. In other words, _The Analects_ is read in the light of _The Analects._This results in a truer understanding of Confucius' thought than the traditional interpretation and paves the way for a re-assessment of its importance in the history of Chinese thought and its relevance to the present day world.This volume also contains an introduction to the life and teachings of Confucius, and three appendices on the events in the life of Confucius, on his disciples, and on the composition of _The Analects._.

Cultural ethical dilemmas occur when ethical research practices, as prescribed by the research ethics codes of Western research institutions, conflict with the cultural and social norms of non-Western researchers and their participants. Thus, insider-researchers working with participants from similar cultural backgrounds may experience ethical dilemmas that result in disconcerting cultural estrangement from their communities. Using reflexive narratives, the author identifies moments of cultural ethical dilemmas that necessitate a choice between two competing sets of values. Working out of a Western university, (...) the narratives reflect on cultural ethical dilemmas relating to non-coercion, confidentiality, and beneficence, encountered during interviews in the researcher’s community. Analyzed through the lens of Confucian social and ethical behavior, the paper asks whether there is a need for East–west polarization, or whether research ethics codes based on Western worldviews can be reconciled with Confucian worldviews. The paper suggests the “Middle Way” approach to reconciling and integrating the diverse worldviews of ethics, through the use of an ethical reflexive process that engenders trust in the research process and resolves cultural ethical dilemmas.
