Much of what we know and love about music is based on implicitly acquired mental representations of musical pitches and the relationships between them. While previous studies have shown that these mental representations of music can be acquired rapidly and can influence preference, it is still unclear which aspects of music influence learning and preference formation. This article reports two experiments that use an artificial musical system to examine two questions: (1) which aspects of music matter most for learning, and (...) (2) which aspects of music matter most for preference formation. Two aspects of music are tested: melody and harmony. In Experiment 1 we tested the learning and liking of a new musical system that is manipulated melodically so that only some of the possible conditional probabilities between successive notes are presented. In Experiment 2 we administered the same tests for learning and liking, but we used a musical system that is manipulated harmonically to eliminate the property of harmonic whole-integer ratios between pitches. Results show that disrupting melody (Experiment 1) disabled the learning of music without disrupting preference formation, whereas disrupting harmony (Experiment 2) does not affect learning and memory but disrupts preference formation. Results point to a possible dissociation between learning and preference in musical knowledge. (shrink)

Through the use of some purposeful anachronisms, Tom Stoppard uses his 1993 play Arcadia to explore the effects on man's psyche of the transition from Newton's Laws to the laws of thermodynamics and from thermodynamics to chaos theory. However, remarkably similar reactions to these changes are also reflected in works from the actual time periods following these shifts in scientific understanding. Modernist literature is believed by many to reflect a sense of depression about the implications of the second law of (...) thermodynamics, which is exemplified in T. S. Eliot's 1922 poem The Waste Land. Likewise, the comfort provided by the revisions to thermodynamics made by chaos theory are reflected frequently in contemporary popular culture, such as in the current television series Numb3rs. Through the invocation of science, all three works suggest that man is uncomfortable with too much predictability and that comfort can instead be found in chaos and unpredictability. (shrink)

Play and Exploration in Animals — A Comparative Analysis Exploratory behavior and play are very often discussed together. However, despite many similarities they are two distinct forms of behavior. They have different evolutionary histories and they develop in different ways. Both forms of behavior play a crucial role in the development of sophisticated and complex psyche. The paper discusses similarities and differences between exploration and play. The hypothesis of the joint development of exploration, play and animal intelligence is proposed.

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

We argue that music can serve as a time-sensitive lens into the interplay between instrumental and ritual stances in cultural evolution. Over various timescales, music can switch between pursuing an end goal or not, and between presenting a causal opacity that is resolvable, or not. With these fluctuations come changes in the motivational structures that drive innovation versus copying.

In lieu of an abstract, here is a brief excerpt of the content:Subjective Experiences of Tourette SyndromeBeyond the Premonitory UrgeThe authors report no conflicts of interest.There is an evolving recognition in healthcare that the patient's subjective experience needs to be privileged both in understanding clinical phenomena and also ensuring the salience of outcomes used to evaluate the impact of treatment interventions. This is reflected in the expansion of patient-reported outcome measures to capture a person's perception of their own health, and (...) the increasing requirement of involving people with lived experience in the co-design of research studies (National Health and Medical Research Council, 2016) and care improvement initiatives. In mental health it has been long understood that observable behavioral phenomena can only partially inform clinical understanding of the experience of the patient living with the condition. However, capturing the patient's subjective experience faithfully remains a challenge.Tourette syndrome (TS) is a complex condition in which there are clearly observable behavioral phenomena (vocal and motor tics, compulsive and socially inappropriate behaviors), but also a broad and varied range of subjective phenomena reported by different individuals. These may include sensory phenomena such as the premonitory sensory urge preceding a tic, compulsions to touch things a certain number of times or do something repeatedly until it feels "just right," or bothersome intrusive thoughts or images. To further complicate the picture most patients with TS have one or more co-occurring conditions such as attention deficit hyperactivity disorder, obsessive-compulsive disorder, and anxiety, which may actually cause a greater burden of dysfunction and distress than the Tourette symptoms.In their paper, Curtis-Wendlandt et al. (2024) challenge the dependence of current psychiatric diagnostic criteria (e.g., the Diagnostic and Statistical Manual of Mental Disorders, 5th edition) on observable tics, and propose a broader and more dimensional approach to nosology which incorporates sensory, cognitive and affective phenomena. [End Page 47] Data from interviews they conducted identified that premonitory phenomena and urge experiences in tic disorders are more complex and diverse than what is currently reflected in the literature and clinical scales. They also interviewed participants who reported "no urges" or "no premonitory sensations." They commented that the literature generally treats reports of urge absences at face value, and does not address the likelihood that such reports may be ambiguous or problematic. Overall, they concluded that their research suggests that premonitory urges in TS are a complex and diverse phenomenon that requires further study. This reflects with our clinical experience in working with TS patients. Although a large proportion of older patients describe sensory-based premonitory urges, descriptions are not homogenous, with many describing other experiences preceding their tics.When evaluating a patient's response to an intervention (either behavioral or pharmacological) clinicians incorporate a range of information. This includes the severity of their tics (number, type, frequency, intensity, and associated impairment), as well as their mood, participation and performance in study, work, and social activities, and overall quality of life. Standard clinical practice would not typically include assessment of some of the subjective experiences which precede tics. If it was accepted that these subjective phenomena are indeed salient to the patient's well-being, then a challenge would be how to consistently and reliably capture these feelings to operationalize a comprehensive patient-centered assessment.The primary evidence-based treatment for tic disorders, comprehensive behavioral intervention for tics (CBIT), involves training to increase the awareness of premonitory urges (Woods et al., 2008). Furthermore, successful 'blocking' of tics during the course of CBIT requires the patient to be aware of premonitory urges. Clinicians having a better understanding of the complexity and diversity of experiences which precede tics, as well as using open-ended questioning styles, may assist with improving CBIT outcomes.

We compare and contrast the 60 commentaries by 109 authors on the pair of target articles by Mehr et al. and ourselves. The commentators largely reject Mehr et al.'s fundamental definition of music and their attempts to refute (1) our social bonding hypothesis, (2) byproduct hypotheses, and (3) sexual selection hypotheses for the evolution of musicality. Instead, the commentators generally support our more inclusive proposal that social bonding and credible signaling mechanisms complement one another in explaining cooperation within and competition (...) between groups in a coevolutionary framework (albeit with some confusion regarding terminologies such as “byproduct” and “exaptation”). We discuss the proposed criticisms and extensions, with a focus on moving beyond adaptation/byproduct dichotomies and toward testing of cross-species, cross-cultural, and other empirical predictions.

Patientenselbstbestimmung und Patientenverfügungen haben zunehmende Bedeutung und Beachtung erfahren. In der vorliegenden qualitativen Studie wurden 15 Patientinnen und Patienten mit amyotropher Lateralsklerose —einer unheilbaren, chronisch-degenerativen Erkrankung mit vorhersehbarer Symptomatik—interviewt, um zu erfahren, welche Werte und Kriterien sie bei prospektiven Entscheidungen am Lebensende und bei der Abfassung von PV zugrunde legen. Die Auswertung erfolgte nach der Methode der „grounded theory“. Die befragten Patientinnen und Patienten befürworteten einen Verzicht auf lebenserhaltende Behandlungen, wenn sie keine hinreichenden Lebensmöglichkeiten mehr sahen, d. h. wenn sie (...) die aktuelle Lebensqualität für unzureichend erachteten und die Chance auf Besserung als gering einschätzten. Dem Patientenwillen sprachen sie bei der Entscheidungsfindung ein Vetorecht zu. Patientenverfügungen fassten sie erst ab, als sie keine Hoffnung mehr auf Besserung ihrer Erkrankung hatten. Sie verstanden diese als Instrumente zur vorsorglichen Erklärung ihres Wunsches, auf lebensverlängernde Maßnahmen zu verzichten, wenn die LM inakzeptabel geworden sind. Damit wollten sie sich gegenüber dem Arzt absichern, den sie in der Rolle eines Anwalts des Lebens sahen und mit dem sie daher ihre Behandlungswünsche nicht besprochen haben. Trotz vorhersehbarer Symptomatik legten sie in ihren PV keine spezifischen Behandlungswünsche nieder, sondern verwendeten allgemeine Formularmuster ohne konkreten Bezug zu ihrer Erkrankung. Daher bestehen auch bei dieser Patientengruppe Zweifel, ob die PV in einer konkreten Behandlungssituation hilfreich sind. (shrink)

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)

Music-based interventions (MBI) have become increasingly widely adopted for dementia and related disorders. Previous research shows that music engages reward-related regions through functional connectivity with the auditory system, but evidence for the effectiveness of MBI is mixed in older adults with mild cognitive impairment (MCI) and Alzheimer’s disease (AD). This underscores the need for a unified mechanistic understanding to motivate MBIs. The main objective of the present study is to characterize the intrinsic connectivity of the auditory and reward systems in (...) healthy aging individuals with MCI, and those with AD. Using resting-state fMRI data from the Alzheimer’s Database Neuroimaging Initiative, we tested resting-state functional connectivity within and between auditory and reward systems in older adults with MCI, AD, and age-matched healthy controls (N = 105). Seed-based correlations were assessed from regions of interest (ROIs) in the auditory network (i.e., anterior superior temporal gyrus, posterior superior temporal gyrus, Heschl’s Gyrus), and the reward network (i.e., nucleus accumbens, caudate, putamen, and orbitofrontal cortex). AD individuals were lower in both within-network and between-network functional connectivity in the auditory network and reward networks compared to MCI and controls. Furthermore, graph theory analyses showed that the MCI group had higher clustering and local efficiency than both AD and control groups, whereas AD individuals had lo... (shrink)

Psyche: Inventions of the Other brings together for the first time twenty-eight essays by Jacques Derrida that both advance his reflection on many issues, such as psychoanalysis, architecture, negative theology, theater, translation, politics, war, nationalism, and religion and carry on his engagement with a number of key thinkers and writers: Kant, Heidegger, Levinas, Lacoue-Labarthe, Freud, Flaubert, Barthes, and de Certeau, among others.

La Société mathématique de France (SMF) créée en 1872 pour promouvoir les travaux des mathématiciens français accueille rapidement le polytechnicien Charles-Ange Laisant (1841-1920) qui s’investit par ailleurs dans de multiples communautés savantes à la fin du xixe siècle. Son implication durable, ses itinéraires d’administrateur et d’auteur permettent, à partir des renseignements fournis par le Bulletin de la SMF, une approche originale de la circulation de ses travaux au sein de la Société. Une étude des comptes rendus de séances met (...) en lumière tant sa production d’écrits mathématiques proprement dits que ses interventions orales sur des sujets variés lors de ces réunions. L’exemple de celui qui sera président de la SMF en 1888 offre ainsi une perspective particulière sur les mathématiques discutées lors des réunions de la Société, sur les liens qui se tissent avec d’autres cercles savants ou sur les réseaux et collaborations ponctuelles à l’intérieur même de la SMF.
