Human Cognition Through the Lens of Social Engineering Cyberattacks.Rosana Montañez,Edward Golob &Shouhuai Xu -2020 -Frontiers in Psychology 11:528099.detailsSocial engineering cyberattacks are a major threat because they often prelude sophisticated and devastating cyberattacks. Social engineering cyberattacks are a kind of psychological attack that exploits weaknesses in human cognitive functions. Adequate defense against social engineering cyberattacks requires a deeper understanding of what aspects of human cognition are exploited by these cyberattacks, why humans are susceptible to these cyberattacks, and how we can minimize or at least mitigate their damage. These questions have received some amount of attention, but the state-of-the-art (...) understanding is superficial and scattered in the literature. In this paper, we review human cognition through the lens of social engineering cyberattacks. Then, we propose an extended framework of human cognitive functions to accommodate social engineering cyberattacks. We cast existing studies on various aspects of social engineering cyberattacks into the extended framework, while drawing a number of insights that represent the current understanding and shed light on future research directions. The extended framework might inspire future research endeavor toward a new sub-field that can be called Cybersecurity Cognitive Psychology, which tailors or adapts principles of Cognitive Psychology to the cybersecurity domain while embracing new notions and concepts that are unique to the cybersecurity domain.

Do Bond Investors Care About Engagement Auditors’ Negative Experiences? Evidence from China.Guangming Gong,Liang Xiao,Si Xu &Xun Gong -2019 -Journal of Business Ethics 158 (3):779-806.detailsUsing data from China, where the identity of engagement auditors is disclosed, we find significant relationships between engagement auditors’ negative experiences and the costs of corporate bonds. Further tests differentiate field and review auditors’ experiences, and we find that both field and review auditors’ negative experiences are significantly related to higher costs of corporate bonds. In addition, we find that the above results are significant only when the engagement auditors are affiliated with non-Big10 audit firms. Using path analysis, we find (...) that credit rating is a possible channel through which information on engagement auditors’ negative experiences can transfer to bond investors. Regarding non-price terms, we conclude that engagement auditors with negative experiences are associated with smaller bond sizes, shorter bond maturities, a higher likelihood of requiring collateral, and more restrictive covenants. Further analyses also show that the effects of engagement auditors’ negative experiences on the costs of corporate bonds are less pronounced for well-governed firms. To show that our results obtained from China’s corporate bond market are relevant to loan markets, we replicate the above tests using a Chinese sample, and the results from the loan market are consistent with those from the corporate bond market. Overall, our empirical results suggest that investors are indeed concerned with engagement auditors’ negative experiences. (shrink)
Link Trustworthiness Evaluation over Multiple Heterogeneous Information Networks.Meng Wang,Xu Qin,Wei Jiang,Chunshu Li &Guilin Qi -2021 -Complexity 2021:1-11.detailsLink trustworthiness evaluation is a crucial task for information networks to evaluate the probability of a link being true in a heterogeneous information network. This task can significantly influence the effectiveness of downstream analysis. However, the performance of existing evaluation methods is limited, as they can only utilize incomplete or one-sided information from a single HIN. To address this problem, we propose a novel multi-HIN link trustworthiness evaluation model that leverages information across multiple related HINs to accomplish link trustworthiness evaluation (...) tasks inherently and efficiently. We present an effective method to evaluate and select informative pairs across HINs and an integrated training procedure to balance inner-HIN and inter-HIN trustworthiness. Experiments on a real-world dataset demonstrate that our proposed model outperforms baseline methods and achieves the best accuracy and F1-score in downstream tasks of HINs. (shrink)

How to Better Motivate Customers to Participate in the Self-Design Process: A Conceptual Model in Underlying Self-Congruence Mechanism.Baojun Yu,Hangjun Xu &Brooke Emery -2020 -Frontiers in Psychology 11.detailsThe voluntary shift of responsibility from the producer to the consumer is one feature of self-design activities. Past research emphasizes the economic gains of such customer co-creation. However, the psychological mechanism underlying customer co-creation behavior is still not fully understood. Notably, the goal-driven self-congruence nature of customer co-creation is mostly ignored in the co-creation literature. The objective of this research is to firstly develop a conceptual understanding of how co-creation literature can be related to the self-congruence theory. Furthermore, this study (...) also extends the original self-congruence theory by arguing the differential role of actual and ideal self-congruence on the relationship between self-congruence and customers’ willingness to participate in the co-creation process. Two laboratory experiments were conducted to examine whether self-congruence plays a prominent role in motivating customers to participate in the self-design process. Specifically, both the actual self-congruence and ideal self-congruence are positively related to customers’ willingness to participate in the self-design process is hypothesized. Moreover, it is expected that product styles and different consumption situations may strengthen the relationship between actual/ideal self-congruence and customers’ willingness to participate in the self-design process. Theoretical and practical implications are also discussed. (shrink)

The Tactile-Visual Conflict Processing and Its Modulation by Tactile-Induced Emotional States: An Event-Related Potential Study.Chengyao Guo,Nicolas Dupuis-Roy,Jun Jiang,Miaomiao Xu &Xiao Xiao -2021 -Frontiers in Psychology 12.detailsThis experiment used event-related potentials to study the tactile-visual information conflict processing in a tactile-visual pairing task and its modulation by tactile-induced emotional states. Eighteen participants were asked to indicate whether the tactile sensation on their body matched or did not match the expected tactile sensation associated with the object depicted in an image. The type of tactile-visual stimuli and the valence of tactile-induced emotional states were manipulated following a 2 × 2 factorial design. Electrophysiological analyses revealed a mismatched minus (...) matched negative difference component between 420 and 620 ms after stimulus onset in the negative tactile-induced emotional state condition. This ND420-620 component was considered as a sign of the cross-modal conflict processing during the processing of incongruent tactile-visual information. In contrast, no significant mismatched minus matched negative difference component was found in the positive tactile-induced emotional state condition. Together, these results support the hypothesis that a positive emotional state induced by a positive tactile stimulation improves tactile-visual conflict processing abilities. (shrink)
What Influences Consumers’ Intention to Purchase Innovative Products: Evidence From China.Jie Li,Fan Guo,Jialin Xu &Zucheng Yu -2022 -Frontiers in Psychology 13.detailsDrawing on the theory of planned behavior, we investigate the legitimacy of platform governance and whether consumers with greater ranges of risk propensity are more likely to purchase innovative products. This study develops a moderated mediation model involving risk propensity, cognitive legitimacy, purchase intention and perceived benefit. To examine our hypotheses, we conducted a survey of 315 consumers from Shanghai, China. The results reveal that risk propensity is positively related to consumers’ purchase intentions, in which cognitive legitimacy plays a mediating (...) role. Furthermore, the interaction suggests that perceived benefit moderates the relationship between risk propensity and cognitive legitimacy. (shrink)
Sharing or Not: Psychological Motivations of Brand Rumors Spread and the Stop Solutions.Xu Zhang,Hong Zhu,Yu Hwang &Chuqu Xiao -2022 -Frontiers in Psychology 13.detailsBrand rumors can harm brands’ image and bring significant impacts on customers’ decision-making and sharing behavior. Finding practical strategies for preventing the spread of brand rumors continues to be a challenge. Building on the social contagion theory, the current research enriches the discussion on understanding why people spread rumors and how to deal with the spreading of rumors. Sharing brand rumors is motivated by a variety of complex psychological reasons, but prior research didn’t adequately analyze the problem from a complexity (...) perspective. Therefore, using a sample of 416 interviewers within eight types of brand rumors, this study employs fuzzy-set qualitative comparative analysis to investigate the combination of rumor psychological communication motivations in brand activities and solutions to prevent the spread of brand rumors. The current study discoveries three and two first-level configurational solutions, respectively, that can promote positive and negative rumor spreading. To summarize, emotional stimulation is a key component in the spread of rumors; altruism and relationship management motivation can coexist at times; and untrusted rumors are disseminated through other motivation factors. Solutions to prevent rumors from spreading are also provided. Furthermore, the findings help to understand the psychology of configurational motivation and how it can help brands reduce the spread of brand rumors. Finally, these discoveries’ theoretical contributions and practical implications are presented. (shrink)
The Digital Entrepreneurship Era: How to Motivate Innovativeness in Middle Management Teams? The Vertical Organisational Pervasiveness of Chief Executive Officer Entrepreneurial Orientation.Xu Zhang,Yueyue Liu,Xiulin Geng &Danxia Wei -2022 -Frontiers in Psychology 13.detailsSocial information processing theory suggests that the chief executive officer’s entrepreneurial orientation is an organisational signal that influences the members’ innovativeness. Middle management teams are expected to be more innovative as they connect senior managers with frontline managers in the dynamic competitive environment of the digital economy. How CEOs guide MMT innovations through EO becomes critical in the process of capturing opportunities and creating value. However, previous research has failed to adequately identify distinct CEO EO manifestations with organisational contexts configurations (...) that influence MMTs innovation. Thus, based on differences in organisational contexts and MMTs’ cognition, this study thoroughly investigates how the vertical manifestation of CEO EO impacts the innovativeness of MMTs. We used fuzzy-set qualitative comparative analysis on a sample of 117 organisations to determine which configurations of CEO EO vertical penetration within an organisation can stimulate MMT innovativeness. The study discovered four first-level configurations that support stimulating MMT innovativeness respectively when the CEO EO is fully or partially manifested, and without the CEO EO. Moreover, we found the internal reasons for MMTs’ information interpretation heterogeneity, which is critical for realising the coordination and unity of entrepreneurial cognition and behaviours. Finally, these findings’ theoretical and practical implications are discussed. (shrink)
The Reducibility of Generalized Syllogisms with the Quantifiers in Square {not all} and Square {most}.Zhipeng Yu &Jing Xu -2024 -Philosophy International Journal 7 (4):1-4.detailsTo explore the reducibility of non-trivial generalized syllogisms with the quantifiers in Square {not all} and Square {most}, this paper first gives the formalization of generalized syllogisms on the basis of set theory, and then proves the validity of the generalized syllogism EMO-3 by first-order logic and generalized quantifier theory; Finally, with the help of some reductive operations, the other 20 valid generalized syllogisms are deduced from the syllogism EMO-3. In other words, there are the reducible relationships between/among the 21 (...) valid syllogisms. The reason for this is that any quantifier in a square can define the other three quantifiers. This research method is applicable to the study of syllogisms with quantifiers in other squares. (shrink)

Netherworld Marriage in Ancient China: Its Historical Evolution and Ideological Background.Chunjun Gu &Keqian Xu -2014 -Journal for the Study of Religions and Ideologies 13 (38):78-109.detailsThe netherworld marriage or the wedding for dead persons is a folk religious ritual in ancientChina. It is based on ancient Chinese folk belief of afterlife in the netherworld. Through a textual research and investigation based on relevant historical records and other ancient documents, as well as some archeological discoveries, this paper tries to give a brief account of the origin and development of netherworld marriage and its cultural and ideological background in ancient China. It finds that netherworld marriage might (...) originate from human sacrifice in early ancient times, and its name varies in different periods. It has gone through its prevailing in the Tang Dynasty, declining in the Song and Yuan Dynasties, and reviving again in the Ming and Qing Dynasties. During the long history, this custom was generally criticized and condemned by orthodoxy Confucian intellectuals, yet it was practiced and sometimes even prevailed among both noble class and common people, due to its deep root in the folk belief. The paper also intends to clarify some misconceptions and misunderstandings concerning the study of this unique cultural phenomenon. (shrink)
Memetic Theory in Music Education: A Philosophical and Empirical Study on Integrating Listening, Reading, and Playing in Piano Teaching.Meilin Wang &Min Xu -2024 -European Journal for Philosophy of Religion 16 (3):216-234.detailsMusic is the universal language of mankind. The process of learning music can be understood as the process of constantly copying and spreading cultural memes. The term "mime" here comes from meme theory, which is a theory that studies cultural imitation and aims to explore the evolutionary model of cultural information dissemination. According to the principle of meme theory, music education itself is a process of cultural dissemination, which is transmitted to different meme carriers through imitation and replication. At present, (...) music education, especially instrumental music education, focuses on teaching performance skills, so there are many performers and educators who "only focus on skills". The author believes that this process should be based on the transmission of metaphysical music culture to be more in line with the philosophical meaning of education? Is education based on meme theory more effective? In order to verify this view, the author selected 20 students from a primary school and conducted a piano teaching experiment lasting 7 months. In the end, it was proved that the piano teaching model of " listening, reading, and playing" based on meme theory has a more benign improvement on students, and also revealed the philosophical significance of music education under the perspective of meme theory and the practical path of the future development of music education.

Interpersonal Neural Synchronization Predicting Learning Outcomes From Teaching-Learning Interaction: A Meta-Analysis.Liaoyuan Zhang,Xiaoxiong Xu,Zhongshan Li,Luyao Chen &Liping Feng -2022 -Frontiers in Psychology 13.detailsIn school education, teaching-learning interaction is deemed as a core process in the classroom. The fundamental neural basis underlying teaching-learning interaction is proposed to be essential for tuning learning outcomes. However, the neural basis of this process as well as the relationship between the neural dynamics and the learning outcomes are largely unclear. With non-invasive technologies such as fNIRS, hyperscanning techniques have been developed since the last decade and been applied to the field of educational neuroscience for simultaneous multi-brain scanning. (...) Hyperscanning studies suggest that the interpersonal neural synchronization during teaching-learning interaction might be an ideal neural biomarker for predicting learning outcomes. To systematically evaluate such a relationship, this meta-analysis ran on a random-effects model on 16 studies with 23 independent samples. Further moderator analyses were also performed to examine the potential influences of the style, mode, content, and the assessment method of learning outcomes. The random-effects modeling results confirmed a robust positive correlation between INS and learning outcomes. Subsequent analyses revealed that such relationship was mainly affected by both interaction style and mode. Therefore, the present meta-analysis provided a confirmatory neurocognitive foundation for teaching-learning interaction, as well as its relation to the learning outcomes, consolidated future learning and teaching studies in various disciplines including second language education with a firm methodological reference.

Gendered Independence and Submission: Wang Fengyi's Moral Philosophy of Education and Manchukuo.Wenqing Zhao &Aymeric Xu -2024 - In Shaun O'Dwyer,Confucianism at war: 1931-1945. Abingdon, Oxon: Routledge. pp. 153-172.detailsThe discourse on Confucianism during the early Republican Era has predominantly revolved around debates among intellectuals and societal elites. This study shifts the focus to the grassroots reconstruction of Confucianism undertaken by Wang Fengyi, a peasant theorist, practitioner, and educator who played a pivotal role in the “the Way of the Virtuous” (shanrendao) movement in Northeastern China during the late nineteenth and early twentieth centuries. Wang was a staunch advocator for the education and literacy of peasant women, who occupied the (...) lowest rungs of society. This chapter delves into his moral philosophy of education, which centers around the idea that women’s literacy is a moral issue. Furthermore, this chapter examines the convergence between Wang Fengyi’s gendered moral philosophy of education and the wartime educational ideology and mobilization efforts of the Japanese colonial administration in Manchukuo. This alignment was conducive – during the last years of Wang’s life – to the co-optation of his initiatives by the colonial administration, in their efforts to reach the impoverished underclass in Manchukuo.

Composition as Nonlinear Combination in Semantic Space: A Computational Characterization of Compound Processing.Tianqi Wang &Xu Xu -2025 -Cognitive Science 49 (2):e70039.detailsMost Chinese words are compounds formed through the combination of meaningful characters. Yet, due to compositional complexity, it is poorly understood how this combinatorial process affects the access to the whole‐word meaning. In the present study, we turned to the recent development in compositional distributional semantics, and employed a deep neural network to learn the less‐than‐systematic relationship between the constituent characters and the compound words. Based on the compositional representations derived from the computational model, we investigated the combinatorial process in (...) terms of the degree of overlap between the compositional and the lexicalized representations as well as the degree of distinctness of the compositional representation. Analyses of lexical decision and eye‐tracking data revealed the effects of both compositional attributes over and above the effects of constituent character features and compound features, indicating an active engagement of the combinatorial process in compound processing. Moreover, with the increase of compound frequency, and thus the increased likelihood that the holistic route prevails, these compositional effects appeared to be dampened. These findings, therefore, provided a computational characterization for the dual‐route framework, which sheds light on the universal process of compound comprehension across different languages.

Testing Effects of Foreign Language Listening Anxiety on Chinese University Students' English Listening Test Performance.Meihua Liu &Hongliang Xu -2021 -Frontiers in Psychology 12.detailsThe present research explored how foreign language listening anxiety affected Chinese university students' English listening test performance and how proficiency and gender mediated the effects of FLLA on the latter. Two different populations from two universities in China answered the 20-item Foreign Language Listening Anxiety Scale as well as a demographic questionnaire and took an English listening test. Analyses of the collected data revealed the following major findings: Five latent factors underlay the FLLAS, when working alone, FLLA significantly negatively predicted (...) students' English listening test performance, and when working with proficiency and gender, English proficiency level, gender and FLLAS2 significantly predicted students' English listening test performance. These findings confirm the negative effects of FLLA on students' English listening test performance. They also indicate that English proficiency and gender mediate FLLA's effects on the latter, with English proficiency not only directly but also indirectly affecting the latter. (shrink)

Early confucian principles: The potential theoretic foundation of democracy in modern china.Keqian Xu -2006 -Asian Philosophy 16 (2):135 – 148.detailsThe subtle and complex relation between Confucianism and modern democracy has long been a controversial issue, and it is now again becoming a topical issue in the process of political modernization in contemporary China. This paper argues that there are some quite basic early Confucian values and principles that are not only compatible with democracy, but also may become the theoretic foundation of modern democracy in China. Early Confucianism considers 'the people's will' as the direct representative of 'Heaven's will', with (...) which it legitimizes political power. Confucian theory of 'human nature is good' endorses equal potential good for every man. These principles can be used in reasoning towards a system of democracy. In terms of decision-making, the Confucian 'Doctrine of the Mean' accords with certain democratic principles. The independent personality and committed individualism advocated by early Confucianism is a required civic merit in a democratic society. These fundamental Confucian principles, through contemporary hermeneutics, may provide a philosophic grounding for democracy and support the construction of a democratic system with a Chinese dimension. To get democracy rooted in the spirit of traditional Chinese culture will benefit the healthy and smooth development of democracy in China. (shrink)
Large number discrimination in 6-month-old infants.Fei Xu &Elizabeth S.

The capacities to represent approximate numerosity found in adult animals and humans evidently develop in human infants prior to language and symbolic counting.
Educational philosophy – East, West, and beyond: A reading and discussion of Xueji.Xu Di -2017 -Educational Philosophy and Theory 49 (5):442-451.detailsThis article analyzes Xueji and discusses some of the myths and facts in Western perceptions of Chinese educational practice. It also looks at the similarities and contrasts between Eastern and Western conceptions of teaching and learning. A careful study of Xueji will help in understanding some common Western misunderstandings and misperceptions of Chinese pedagogic practices, in particular, the views that Chinese educational practices and ideas are authoritarian, encourage obedience to authority over individual inquiry, promote memorization over comprehension, and are non-individualized (...) to the point of encouraging uniformity over diversity. A better understanding of the classical Chinese approach to learning and teaching will foster a deeper understanding of the nature of pedagogic practices. Such an understanding will enable us to make a better assessment of the similarities and differences between Chinese and Western conceptions of learning and teaching with a view to sharing ideas from both cultural and philosophical perspectives. Throughout the discussion, this article will seek insights for teaching and learning today in a global context. (shrink)

Epistemic Logic with Evidence and Relevant Alternatives.Zhaoqing Xu &Bo Chen -2018 - In Hans van Ditmarsch & Gabriel Sandu,Jaakko Hintikka on Knowledge and Game Theoretical Semantics. Cham, Switzerland: Springer. pp. 535-555.detailsStarting with Jaakko Hintikka’s seminal work, epistemic logic has now grown up to a huge academic industry. When we look back to its history, however, there is a practical paradox. While Hintikka’s original purpose was to facilitate epistemological discussion, most subsequent work of epistemic logic has been done outside of philosophy, and has been ignored by most mainstream epistemologists. At the current point, one might naturally wonder, does epistemic logic still have something to do with epistemology? Along with Hintikka and (...) a growing number of formal epistemologists, we believe the answer is “yes”. Contemporary epistemology has largely focused on the goal of providing an analysis of knowledge and an answer to skepticism. To avoid skepticism, many epistemologists prefer to define knowledge in terms of evidence and relevant alternatives. A typical saying is that “in order to know that p, one only needs evidence to eliminate all relevant alternatives, rather than all alternatives”. We see such a project as perfectly congenial to the spirit of Hintikka’s epistemic logic. In this paper, we propose an epistemic logic to deal with evidence and relevant alternatives explicitly, and extend EREL to its dynamic version to investigate how different notions of knowledge behavior with the decrease and increase of relevant alternatives. To illustrate its philosophical application, we provide a new formalization of the so called factivity problem of epistemic contextualism. We conclude with some remarks on further developments of our framework. (shrink)
