In the near future, vehicles will gradually gain more autonomous functionalities. Drivers’ activity will be less about driving than about monitoring intelligent systems to which driving action will be delegated. Road safety, therefore, remains dependent on the human factor and we should identify the limits beyond which driver’s functional state (DFS) may no longer be able to ensure safety. Depending on the level of automation, estimating the DFS may have different targets, e.g. assessing driver’s situation awareness in lower levels of (...) automation and his ability to respond to emerging hazard or assessing driver’s ability to monitor the vehicle performing operational tasks in higher levels of automation. Unfitted DFS (e.g., drowsiness) may impact the driver ability respond to taking over abilities. This paper reviews the most appropriate psychophysiological indices in naturalistic driving while considering the DFS through exogenous sensors, providing the more efficient trade-off between reliability and intrusiveness. The DFS also originates from kinematic data of the vehicle, thus providing information that indirectly relates to drivers behaviour. The whole data should be synchronously processed, providing a diagnosis on the DFS, and bringing it to the attention of the decision maker in real time. Next, making the information available can be permanent or intermittent (or even undelivered), and may also depend on the automation level. Such interface can include recommendations for decision support or simply give neutral instruction. Mapping of relevant psychophysiological and behavioural indicators for DFS will enable practitioners and researchers provide reliable estimates, fitted to the level of automation. (shrink)

Research indicates that people value music primarily because of the emotions it evokes. Yet, the notion of musical emotions remains controversial, and researchers have so far been unable to offer a satisfactory account of such emotions. We argue that the study of musical emotions has suffered from a neglect of underlying mechanisms. Specifically, researchers have studied musical emotions without regard to how they were evoked, or have assumed that the emotions must be based on the mechanism for emotion induction, (...) a cognitive appraisal. Here, we present a novel theoretical framework featuring six additional mechanisms through which music listening may induce emotions: (1) brain stem reflexes, (2) evaluative conditioning, (3) emotional contagion, (4) visual imagery, (5) episodic memory, and (6) musical expectancy. We propose that these mechanisms differ regarding such characteristics as their information focus, ontogenetic development, key brain regions, cultural impact, induction speed, degree of volitional influence, modularity, and dependence on musical structure. By synthesizing theory and findings from different domains, we are able to provide the first set of hypotheses that can help researchers to distinguish among the mechanisms. We show that failure to control for the underlying mechanism may lead to inconsistent or non-interpretable findings. Thus, we argue that the new framework may guide future research and help to resolve previous disagreements in the field. We conclude that music evokes emotions through mechanisms that are not unique to music, and that the study of musical emotions could benefit the emotion field as a whole by providing novel paradigms for emotion induction.

Community-level legal and policy innovations or “experiments” can be important levers to improve health. States and localities are empowered through the 10th Amendment of the United States Constitution to use their police powers to protect the health and welfare of the public. Many legal and policy tools are available, including: the power to tax and spend; regulation; mandated education or disclosure of information, modifying the environment — whether built or natural ; and indirect regulation. These legal and policy interventions can (...) be targeted to specific needs at the community level and are often relatively low-cost, but high impact interventions. As every community is different, effective laws and policies will vary. This freedom allows states and localities to, as Justice Louis Brandeis argued, truly serve as “laboratories of democracy.”.

Neoliberalism co-opts noisy riots like feminism and hardcore music--can melancholic siren songs fight back?

Country music has not gotten much attention in philosophy. I introduce two philosophical issues that country music raises. First, country music is simple. Some people might think that its simplicity makes country music worse; I argue that simplicity is aesthetically valuable. The second issue is country music’s ideal of authenticity; fans and performers think that country should be real or genuine in a particular way. But country music scholars have debunked the idea that country (...) authenticity gets at anything real; widespread ideas about country authenticity are rooted in a racist and fabricated picture of country music. In discussing these two issues, I highlight the importance of community in country music. (shrink)

The claim that listening to extreme music causes anger, and expressions of anger such as aggression and delinquency have yet to be substantiated using controlled experimental methods. In this study, 39 extreme music listeners aged 18–34 years were subjected to an anger induction, followed by random assignment to 10 min of listening to extreme music from their own playlist, or 10 min silence (control). Measures of emotion included heart rate and subjective ratings on the Positive and Negative (...) Affect Scale (PANAS). Results showed that ratings of PANAS hostility, irritability, and stress increased during the anger induction, and decreased after the music or silence. Heart rate increased during the anger induction and was sustained (not increased) in the music condition, and decreased in the silence condition. PANAS active and inspired ratings increased during music listening, an effect that was not seen in controls. The findings indicate that extreme music did not make angry participants angrier; rather, it appeared to match their physiological arousal and result in an increase in positive emotions. Listening to extreme music may represent a healthy way of processing anger for these listeners. (shrink)

Digitized information and network have made an enormous impact on the music and movie industries. Internet piracy is popular and has greatly threatened the companies in these industries. This study tests Hunt-Vitell’s ethical decision model and attempts to understand why and how people share unauthorized music files with others in the peer-to-peer (P2P) network. The norm of anti-piracy, the ideology of free software, the norm of reciprocity, and the ideology of consumer rights are proposed as four deontological norms (...) related to using P2P systems. The model is tested using a scenario survey with four alternatives; the results indicate that the deontological norm of anti-piracy is not a main factor in affecting P2P users’ ethical considerations regarding sharing files with others. This finding suggests that to protect their property rights, record companies should try to realize the consumer benefits brought via new digital and network technology, instead of simply declaring their intellectual property and resisting the innovations resulting from new technologies.

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the (...) most effective activity for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

This introduction to the aesthetics and sociology of music of the German philosopher and music theorist T. W. Adorno is the only book to deal comprehensively with this topic and it has quickly established itself as a classic text.

In this work we present the complex relationship between sound and color in musical creation throughout history that continues to be fruitful in current musical composition. Synesthesia in music establishes a correspondence between sound and color and has been a constant debate since the 17th century. The complex nature of sound appears from ancient Greece in the school of Pythagoras in which the number becomes the configurator of harmony. Since then, different aesthetic attempts have arisen to relate color and (...) sound that reach today's electronic procedures in contemporary music. (shrink)

Many scholars of philosophy, aesthetics, religion, history or social science have ventured to offer a comprehensive explanation of music, one of the most intangible and elusive phenomena in the world. A palaeoanthropological approach, which places music into an evolutionary paradigm, can add important perspectives to our understanding of this phenomenon. To begin with, the question whether music is an adaptation that has survival value in the classical Darwinian sense is contemplated. Views on the origin of music (...) in conjunction with the emergence of language and as a domain for the expression of emotion, linked to music’s benefits for social coherence, are discussed. More recent views on the emergence of consciousness, on semiosis and on music as a manifestation of biocultural co-evolution, especially in conjunction with ritual, are then presented. Finally, the merit of exploiting the concept of play to help account for the systematicity of music’s semiosis is examined.Contribution: In line with the intent of this special collection of articles, the above considerations are placed into the context of materialist versus nonmaterialist perspectives on the emergence of the human mind. The overarching argument is that music contributes crucially to what it means to be human. (shrink)

Music offers a unique opportunity to better understand the organization of the human brain. Like language, music exists in all human societies. Like language, music is a complex, rule-governed activity that seems specific to humans, and associated with a specific brain architecture. Yet unlike most other high-level functions of the human brain - and unlike language - music is a skill at which only a minority of people become proficient. The study of music as a (...) major brain function has for some time been relatively neglected. Just recently, however, we have witnessed an explosion in research activities on music perception and performance and their correlates in the human brain. This volume brings together an outstanding collection of international authorities - from the fields of music, neuroscience, psychology, and neurology - to describe the amazing advances being made in understanding the complex relationship between music and the brain. Aimed at psychologists and neuroscientists, this is a book that will lay the foundations for a cognitive neuroscience of music. (shrink)

This study investigates how background music influences learning with respect to three different theoretical approaches. Both the Mozart effect as well as the arousal-mood-hypothesis indicate that background music can potentially benefit learning outcomes. While the Mozart effect assumes a direct influence of background music on cognitive abilities, the arousal-mood-hypothesis assumes a mediation effect over arousal and mood. However, the seductive detail effect indicates that seductive details such as background music worsen learning. Moreover, as working memory capacity (...) has a crucial influence on learning with seductive details, we also included the learner’s working memory capacity as a factor in our study. We tested 81 college students using a between-subject design with half of the sample listening to two pop songs while learning a visual text and the other half learning in silence. We included working memory capacity in the design as a continuous organism variable. Arousal and mood scores before and after learning were collected as potential mediating variables. To measure learning outcomes we tested recall and comprehension. We did not find a mediation effect between background music and arousal or mood on learning outcomes. In addition, for recall performance there were no main effects of background music or working memory capacity, nor an interaction effect of these factors. However, when considering comprehension we did find an interaction between background music and working memory capacity: the higher the learners’ working memory capacity, the better they learned with background music. This is in line with the seductive detail assumption. (shrink)

Country music critics and scholars have noticed an apparent contradiction between the practical identity of country music and the image of the male country singer as the 'rhinestone cowboy'. In this case, the problem is one of how we can make sense of the rural, working-class, ruggedly masculinity persona common to the genre with its elaborately embroidered, brightly colored, and highly embellished male fashion. The intractability of this problem has led some to argue that the simplest solution is (...) to just deny the legitimacy of country music authenticity discourse altogether. That is, all the genre’s talk of the rural working class is inauthentic and should be discarded. Here, I argue that by accounting for country music authenticity in terms of the genre being a dual character concept, we can fully address the skeptic's worries. Beyond merely being compatible with the Nudie suit however, this notion of authenticity is also our best way of understanding the aesthetic value of the rhinestone cowboy image at all. The resulting picture, in which the suit primarily serves as an epistemic signifier of one’s standing in the country music community, allows for the Nudie suit to function as a class, and sometimes queer, commentary on mainstream culture.

Music may be used to express emotion, to heighten a drama, to emphasize the meaning of a ceremony; but it is nevertheless an abstract art, with no power to represent the world. Representation, as I understand it, is a property that does not belong to music.

Measuring responsiveness to gain accurate diagnosis in populations with disorders of consciousness (DOC) is of central concern because these patients have such complex clinical presentations. Due to the uncertainty of accuracy for both behavioral and neurophysiological measures in DOC, combined assessment approaches are recommended. A number of standardized behavioral measures can be used with adults with DOC with minor to moderate reservations relating to the measures’ psychometric properties and clinical applicability. However, no measures have been standardized for use with pediatric (...) DOC populations. When adapting adult measures for children, confounding factors include developmental considerations for language-based items included in all DOC measures. Given the lack of pediatric DOC measures, there is a pressing need for measures that are sensitive to the complex clinical presentations typical of DOC and that can accommodate the developmental levels of pediatric populations. The music therapy assessment tool for awareness in disorders of consciousness (MATADOC) is a music-based measure that has been standardized for adults with DOC. Given its emphasis on non-language based sensory stimuli, it is well-suited to pediatric populations spanning developmental stages. In a pre-pilot exploratory study, we examined the clinical utility of this measure and explored trends for test-retest and inter-rater agreement as well as its performance against external reference standards. In several cases, MATADOC items in the visual and auditory domains produced outcomes suggestive of higher level functioning when compared to outcomes provided by other DOC measures. Preliminary findings suggest that the MATADOC provides a useful protocol and measure for behavioral assessment and clinical treatment planning with pediatric DOC. Further research with a larger sample is warranted to test a version of the MATADOC that is refined to meet developmental needs of pediatric DOC populations. (shrink)

While feminist aestheticians have long interrogated gendered, raced, and classed hierarchies in the arts, feminist philosophers still don’t talk much about popular music. Even though Angela Davis and bell hooks have seriously engaged popular music, they are often situated on the margins of philosophy. It is my contention that feminist aesthetics has a lot to offer to the study of popular music, and the case of popular music points feminist aesthetics to some of its own limitations (...) and unasked questions. This essay addresses the paucity of work in feminist philosophy and popular music by applying insights from other areas of feminist aesthetics to questions of popular music, and thereby using feminist aesthetics – specifically, Julia Kristea’s notion of female genius and the genius spectator – to critique itself.

Three experiments explored online recognition in a nonspeech domain, using a novel experimental paradigm. Adults learned to associate abstract shapes with particular melodies, and at test they identified a played melody’s associated shape. To implicitly measure recognition, visual fixations to the associated shape versus a distractor shape were measured as the melody played. Degree of similarity between associated melodies was varied to assess what types of pitch information adults use in recognition. Fixation and error data suggest that adults naturally recognize (...) music, like language, incrementally, computing matches to representations before melody offset, despite the fact that music, unlike language, provides no pressure to execute recognition rapidly. Further, adults use both absolute and relative pitch information in recognition. The implicit nature of the dependent measure should permit use with a range of populations to evaluate postulated developmental and evolutionary changes in pitch encoding. (shrink)

This essay considers the way and manner in which a musician and music educator approaches his or her work. It is suggested that anthropomorphic conceptions of music have endured in music education practice in the West. It is proposed that our view of the ‘processes’ of music making, music reception and music learning can be challenged and reconsidered. Heidegger's theory of art is used as a way of rethinking these processes, and of reconsidering our (...) relational dimension with music. The unfolding of music in music‐events occurs as people ‘work‐with’ music and interact with its dimensions in a way that is culturally and dialogically vibrant. Music education can thus become more responsive to changing ‘modes of beings’ in the moment. (shrink)

This is an excerpt from a report that highlights and explores five questions which arose from the workshop on perceptual learning and perceptual recognition at the University of Toronto, Mississauga on May 10th and 11th, 2012.

Music performance anxiety is a commonly present topic among musicians. Most studies on MPA investigated effects of a more general occurrence of MPA on performances. Less is known about individual variations of MPA within a performance, more specifically at the times before, during, and after the performance. This study used a questionnaire to investigate these performance times in order to find out if there occur different types in the variation of the perceived MPA across the performance. The study was (...) performed with 532 musicians; 27% of them being professional orchestra musicians, 45% non-professional orchestra musicians, and 28% non-professional choir singers. The musicians were asked to fill in the Performance-specific Questionnaire for Musicians immediately after a performance. The questionnaire contains three scales regarding symptoms of MPA, functional coping with MPA and performance-related self-efficacy. A cluster analysis was performed on the PQM scales to identify systematic variations. Findings indicate that there are three different types of MPA in the sample studied. Type 1 describes musicians who have few symptoms of MPA throughout the performance, show functional coping with MPA, and have a stable and well-developed self-efficacy. Type 2 describes musicians who begin their performance with rather high symptoms of MPA but can positively reduce these by the end of the performance and show high values in self-efficacy and in functional coping. Type 3 contains musicians who begin their performance with some symptoms of MPA, which increase to the end of the performance. The values of self-efficacy and functional coping in this type are rather low. Of the total sample, half of the musicians were assigned to Type 1 and approximately a quarter each to Type 2 and Type 3. In accordance with the literature, the results confirm the importance of self-efficacy and functional coping for a positive performance experience. (shrink)

Recognising and responding appropriately to emotions is critical to adaptive psychological functioning. Psychopathic traits (e.g. callous, manipulative, impulsive, antisocial) are related to differences in recognition and response when emotion is conveyed through facial expressions and language. Use of emotional music stimuli represents a promising approach to improve our understanding of the specific emotion processing difficulties underlying psychopathic traits because it decouples recognition of emotion from cues directly conveyed by other people (e.g. facial signals). In Experiment 1, participants listened to (...) clips of emotional music and identified the emotional content (Sample 1, N = 196) or reported on their feelings elicited by the music (Sample 2, N = 197). Participants accurately recognised (t(195) = 32.78, p <.001, d = 4.69) and reported feelings consistent with (t(196) = 7.84, p <.001, d = 1.12) the emotion conveyed in the music. However, psychopathic traits were associated with reduced emotion recognition accuracy (F(1, 191) = 19.39, p <.001) and reduced likelihood of feeling the emotion (F(1, 193) = 35.45, p <.001), particularly for fearful music. In Experiment 2, we replicated findings for broad difficulties with emotion recognition (Sample 3, N = 179) and emotional resonance (Sample 4, N = 199) associated with psychopathic traits. Results offer new insight into emotion recognition and response difficulties that are associated with psychopathic traits. (shrink)

This research investigates and analyzes the integration of traditional Chinese music into contemporary music education systems in Ji'an City, Jiangxi Province, China, from an evolutionary perspective. It emphasizes the importance of traditional music education in preserving cultural heritage, fostering creativity, and enhancing holistic student development within the framework of imaginative culture. The study employs a structured approach using the PRISMA methodology to systematically review relevant literature and assess the current status of music education in Ji'an, focusing (...) on course implementation, teacher qualifications, and educational outcomes. The results reveal significant challenges, including the need for qualified educators, standardized curriculum frameworks, and resource allocation for traditional music. It also highlights the positive impacts of traditional music on students' aesthetic, cognitive, and social development. The discussion integrates these findings with existing literature, suggesting the need for innovative pedagogical strategies and technology integration to enhance traditional music education's effectiveness and appeal. The study concludes that effectively integrating traditional Chinese music into Ji'an's education system can promote cultural preservation and improve educational quality, recommending targeted reforms to address the identified challenges. This research contributes valuable insights for educators, policymakers, and researchers, advocating for a comprehensive and culturally responsive approach to music education. (shrink)

Music education has long been linked to various cognitive and developmental benefits for students and enhances cognitive abilities, including concentration and academic achievement. The aim of this study examines the impact of music education on academic achievement, cognitive development, and overall classroom engagement.

In this paper, I consider how it would be possible to think about the historicity of music through Hegel’s thought. I will compare Hegel’s idea with a historical event that is considered relevant in the history of music: Schoenberg’s twelve-tone music, taken here also as a model of immanent negation and Aufhebung of tonal system in music. Furthermore, I will take Schoenberg’s twelve-tone music as an instance and wonder about the role of music and (...) its history in the sociocultural formation (or, in Hegelian words, in the absolute Geist). I divide the exposition into four parts, namely: (1) the position of art before the absolute Geist; (2) a general exposition of art in the Lectures on the Philosophy of Art, placing music as a singular form of art; (3) an analysis of the characteristics of music in Hegel and (4) the comparison with Schoenberg’s twelve-tone music. I conclude that music, as an artistic form, brings the form of an internal feeling of a social subjectivity – a way to feel and understand sounds that transforms itself through history; in turn, both music and the form of an internal feeling of social subjectivity, have a historicity that can be understood as developed dialectically. Along these lines, the beginning of the Twentieth Century in music reveals, through Schoenberg and other composers, new intuitive configurations of this social subjectivity. (shrink)

The enjoyment and pleasure derived from sad music has sparked fascination among researchers due to its seemingly paradoxical nature in producing positive affect. Research is yet to develop a comprehensive understanding of this “paradox.” Contradictory findings have resulted in a great variability within the literature, meaning results and interpretations can be difficult to derive. Consequently, this review collated the current literature, seeking to utilize the variability in the findings to propose a model of differential sad states, providing a means (...) for past and future findings to be interpreted. The proposed model is based on theoretical understanding, as such it requires full empirical support. Comparisons to alternative models, theoretical, clinical, and cognitive implications, as well as future directions are discussed. (shrink)

Il saggio si propone di approfondire due tendenze tipiche della musica contemporanea: la prima è il Minimalismo, movimento rappresentato da musicisti come La Monte Young, Philip Glass and Steve Reich, la seconda è la rave music (come la techno), caratteristica della popular culture nell’era postmoderna. Attraverso il pensiero di Adorno, e a partire dalla sua analisi dialettica del dualismo Schönberg-Stravinskij, il saggio propone una comprensione filosofica di concetti come “ripetizione” e “trascendenza”; l’assenza dello “sviluppo” in gran parte della produzione (...) musicale degli ultimi decenni, nella popular music quanto nella musica colta, dimostra una dispersione del soggetto e dell’individuo, smarrito all’interno di un “eterno ritorno” della struttura ritmica che può essere ricompreso nei termini di un “eterno ritorno dell’identico” e non nei termini di un “eterno ritorno della possibilità”; in quest’ottica, a venire sacrificata è anche la dimensione della trascendenza, che non a caso viene ricercata spesso nell’esotismo dei culti orientali o nel consumo di sostanze stupefacenti. L’insistenza nel Minimalismo della ripetizione come unica ed estrema categoria di riferimento e norma estetica, produrrà infatti nel corso degli ultimi anni una dicotomia apparentemente contraddittoria, ma che invece esprime la medesima matrice logica: da un lato l’invasamento edonistico del beat elettronico della musica dance elettronica, dall’altro la proposta commerciale della produzione industriale della musica pop. Non è un caso che proprio il Minimalismo sia sfociato in entrambe queste due tendenze, mostrandosi come la cifra comune originaria, traducendosi nella musica rave o nella musica rock. (shrink)

Slavoj Žižek is known for quoting with the same enthusiasm the main names of Western Philosophy and the classics of pop culture, cinema, literature, and music. Therefore, in such rich theoretical framework, it is possible to glimpse a few connections that the philosopher himself has not yet developed in detail. This essay is precisely about of these connections. More specifically, this essay can be seen as an endeavor to think some of Žižek’s writings on music having as a (...) main reference the concept of ontological incompleteness. The philosopher discusses the concept of ontological incompleteness based on several areas, from sciences to movies and literature. Notwithstanding, in this specific case musical examples are left aside. Even though Žižek does not analyse music from the perspective of such concept of ontology, it is possible to argue that Žižek’s writings on music already leave some clues and examples that justify an analysis of that kind. That is the task proposed in this critical essay: to present how an approximation between his thoughts on music and on ontology is pos. (shrink)

Xunzi discussed solidarity in two ways, that is, distancing through ritual and unifying through music. Therefore, it can be said that the solidarity is achieved between distancing from and closing to others. In this paper, I try to find an answer to the question how the solidarity is possible in Xunzi's ideas. Xunzi emphasized that individuals are different in discussing the solidarity through the rituals. When they accept the standard for differentiating themselves, they can be unified. In other words, (...) they can form the solidarity with others through the common moral symbol of rituals. However, it is very hard to expect they have common belief or ideas by means of the symbol. Therefore, Xunzi tried to complement the imperfect solidarity of morality by means of music. The solidarity through music is based on human emotions. We can feel enjoyable when we listen to music or dance with others. The emotion of enjoyment is one of the representative phenomena when we reach to the state of flow claimed by Mihaly Csikszentmihalyi. In this state, we feel the breakdown of boundary between us and the others. The emotional entrainment or the breakdown of the boundary does not necessarily mean that we form the solidarity with them. However, people participating in the rituals interpret the symbol of morality in different ways, but can feel oneness with the others just by participating in the same activity or dancing with them by the same rhythm. People who share the same activity have higher chances of forming the common belief. Therefore, the solidarity by music is the source of the one by rituals, and music can make a stronger sense of solidarity than rituals among people. (shrink)
