Referring to the mainstream studies based on the personalization’s hypothesis, which positively evaluates signals of dominance shown by leaders, the analysis of Obama’s rhetoric stays a relevant exception. His risky recall, during his political talks, of his social difficulties as a child of a mixed couple was in fact one of the more surprising aspects of his success. Nevertheless, reactions to his autobiographical sharing were scarcely explored. Based on the idea that these self-disclosures signal his responsivity toward the audience of (...) low social condition and can, therefore, be defined as a sign of humility, this research aims to test if coherence between Obama’s words and his facial expressions of contempt, due to the seriousness of social injustices endured in his childhood, may influence the receivers’ perception of such unexpected communication. Before reading a brief autobiographical sharing taken from a “Back-to-school” speech, a highly ritualized monolog the US President addresses each year to students, 175 Italian participants were presented with a photo of Obama displaying either an expression of contempt or a neutral expression. Comparisons between self-assessments of perceptions and reactions of participants assigned to the two experimental conditions show that a facial expression of contempt, coherent with words describing his school difficulties, has been crucial for perceiving this humble political discourse as authentic and not as a simple socially desirable posturing. More studies seem to be needed, however, to understand how humble speech could enhance the positive face of leaders or backfire against them. (shrink)

Humble leadership can be described as a positive psychological feature that allows leaders to admit their limitations, be open to new ideas, and give a voice to others while also recognizing their merits. The present study explored the persuasive effects of a female politician communicating a humble stance by considering the role emotional displays at play when discussing a moral issue. The results revealed that the politician elicited positive emotions and evaluations of her competence and benevolence, especially when exhibiting a (...) sad facial display, by contributing to the intention to accept the moral gist of her persuasive message. Overall, these ‘gendered’ effects are discussed in relation to the ‘political authenticity’, which can be perceived as high especially when the humble message is connected with several social reasons, as is the case with gender or social status.

On the basis of recent advancements in both neuroscience and archaeology, we propose a plausible biocultural mechanism at the basis of cultural evolution. The proposed mechanism, which relies on the notions of cultural exaptation and cultural neural reuse, may account for the asynchronous, discontinuous, and patchy emergence of innovations around the globe. Cultural exaptation refers to the reuse of previously devised cultural features for new purposes. Cultural neural reuse refers to cases in which exposure to cultural practices induces the formation, (...) activation, and stabilization of new functional and/or structural brain networks during the individual lifespan. The invention of writing is interpreted as a case of cultural exaptation of previous devices to record information, in use since at least the Early Later Stone Age and the beginning of the Upper Paleolithic. The measurable changes in brain structure and functioning caused by learning to read are proposed as an exemplar case of cultural neural reuse. It is argued that repeated cycles of cultural exaptation, development of appropriate strategies of cultural transmission, and ensuing cultural neural reuse represent the fundamental mechanism that has regulated the cultural evolution of our lineage. A general predictive model of when and under which circumstances the proposed mechanism should be expected to occur is proposed, and the relationship of our mechanism with gene-culture coevolutionary models is discussed.

It is hard to define cultural modernity. Nonetheless, apparently there is no match between biological and cultural evolution, between biological and archaeological data. The features of cultural modernity cannot be seen as a direct consequence of the biological origin of our species. A second crucial aspect is that the subsistence strategies, technological and symbolic traditions of Neanderthals are not significantly different from those of modern humans living in Africa and the Near East at the same period. Europe, at the level (...) of human evolution, was a cul-de-sac and not a disseminating centre. Bifaces reached Europe a million years after their invention in Africa. Homo sapiens and Neanderthals thus evolved in parallel, even though speed and cultural forms varied from one population to another. It now seems clear that the features we recognize as ‘modern’ appeared in different regions and in different human groups. It would be the same later with the invention of agriculture, writing, state societies, which appeared separately at several points on the planet. (shrink)

In the following article, I will try to describe and, thus, share with my readers those moments and those segments in my life that have allowed me to be involved in the experience of musical improvisation, which is comprised of the gestures, ideas, and emotions that, together, encompass the musical objects of improvisation, and the desire, the pleasure of sharing these objects in their shaping and creation.

Clarke and Beck's defense of the theoretical construct “approximate number system” is flawed in serious ways – from biological misconceptions to mathematical naïveté. The authors misunderstand behavioral/psychological technical concepts, such as numerosity and quantical cognition, which they disdain as “exotic.” Additionally, their characterization of rational numbers is blind to the essential role of symbolic reference in the emergence of number.

The striking color patterns of butterflies and birds have long interested biologists. But how these animals see color is less well understood. Opsins are the protein components of the visual pigments of the eye. Color vision has evolved in butterflies through opsin gene duplications, through positive selection at individual opsin loci, and by the use of filtering pigments. By contrast, birds have retained the same opsin complement present in early-jawed vertebrates, and their visual system has diversified primarily through tuning of (...) the short-wavelength-sensitive photoreceptors, rather than by opsin duplication or the use of filtering elements. Butterflies and birds have evolved photoreceptors that might use some of the same amino acid sites for generating similar spectral phenotypes across 540 million years of evolution, when rhabdomeric and ciliary-type opsins radiated during the early Cambrian period. Considering the similarities between the two taxa, it is surprising that the eyes of birds are not more diverse. Additional taxonomic sampling of birds may help clarify this mystery. (shrink)

This important new book provides a multidisciplinary overview on different discourses and practices, exploring cutting-edge questions from the burgeoning field of artistic research.

For those of us who do not idealize Proclus's contribution to Platonic scholarship, which is influenced excessively by the conviction that Orphic and Chaldaean texts are working within the same system, the commentaries of Olympiodorus can represent a substantial step forward. The range of issues tackled in his commentaries is often much closer to that expected of a modern commentary than those of his illustrious Athenian predecessor. This is not entirely new, since much the same could be said of Hermias, (...) working within Syrianus's school as Proclus did, and of Damascius when commenting on the Phaedo or Philebus rather than on the Parmenides. Yet our picture of so-called neoplatonism remains dominated by the more... (shrink)

In Memory, History, Forgetting, Ricœur does not provide us with a clear definition of collective memory. In this article, we will try to show how it could nevertheless be described, based on the same text, as the capacity for recognition, by way of reciprocal attribution, memories that are engraved in temporal spaces and are shared with our neighbors and, through them, with strangers. To verify this hypothesis, we will analyse Ricœur’s reflection on architecture as public memory’s engraving into space, presented (...) for the first time in the text “Architecture et narrativité.” Lastly, we will consider imagination and bodily memory, i.e. habit emanating from the act of inhabiting, as the conditions of possibility for the crystallization of memories in shared places.

La storia della filosofia come frontiera. L’itinerario di Nicola Abbagnano - ASBTRACT: L’articolo ricostruisce i momenti fondamentali del percorso storiografico di Nicola Abbagnano, a partire dalla sua tesi di laurea del 1923, Le sorgenti irrazionali del pensiero, fino all’articolo Il lavoro storiografico in filosofia : l’intento di questa analisi è mostrare la centralità e la complessità della Storia della filosofia , non riducibile a semplice "appendice" storiografica del periodo esistenzialistico dell’autore. Vengono esaminate in tale prospettiva le premesse teoriche dell’impostazione storiografica (...) di Abbagnano e le difficoltà che sorgono nel concreto lavoro storiografico: la Storia della filosofia si rivela così anche opera teoretica decisiva nel passaggio al neoilluminismo, che risulta caratterizzato da un profondo ripensamento dei rapporti tra storia e filosofia.

In this article, we argue that Paul Ricœur’s hermeneutics of spaces and the aesthetics vision of the landscape as a performance, based on the contemporary theories of Erika Fischer-Lichte, can integrate each other through the mediation of Mikel Dufrenne’s phenomenology of the a priori. In particular, we will show how the representations and the hermeneutics of a landscape as a peculiar “text” are essentially connected with its the pre-reflective experience, which, being made possible by the activation of precise material – (...) and therefore historical and cultural – a priori, can be thus translated into images and words. By intertwining hermeneutics, phenomenology, and performative esthetics we will provide with a non-reductive philosophical description of a landscape, i.e., a definition that does not neglect the aspects of it suggested by its linguistic pre-comprehension and artistic representations.

BackgroundHeavy media use has been linked to sleep problems in children, which may also extend to the infancy period. While international parent-advisory agencies, such as the American Academy of Pediatrics, advise no screen time before 18 months, parents often do not follow this recommendation. Research on Italian infants’ early access to media is sparse, and only very few studies have investigated links with sleeping habits.MethodTo address this gap, we examined concurrent associations between parent-reported surveys of child technology use and sleeping (...) patterns. The Italian version of the 60 item Comprehensive Assessment of Family Media Exposure Survey, developed as part of a larger international study,, the Brief Screening Questionnaire for Infant Sleep Problems Sadeh, 2004) were completed online by 264 Italian parents of 8- to 36-month-olds and a subset completed the Parenting Stress Index Abidin, 1995) between April 2017 and April 2018.ResultsMore devices located in the child’s room and the more time spent watching TV or using an iPad were associated with less hours of sleep at night. Furthermore, more time spent watching TV or using a smartphone, as well as the number of devices in the room was associated with going to sleep later at night. Instrumental media use was associated with less sleep.ConclusionLike other countries, Italian infants have high levels of exposure to media, and differences in media patterns were associated with sleep patterns. Cultural factors influence both instrumental reasons for media use and sleep practices. Further research should explore how media use may serve to regulate emotion as a function of both contextual factors and individual differences. (shrink)

This study aims to open a critical scenario on the current paradigm of reference for teaching sports techniques by pointing to a methodological perspective that is more in keeping with the theoretical reference framework of the ecological-dynamic approach. Currently, the Constraints-led Approach is considered very useful for teaching sports techniques; however, the transition from pure theory to practice is not so simple and consistent with the heuristic learning paradigm. The purpose is to highlight, starting from the theoretical lines, the methodological (...) applications of the different ways of applying the reference paradigm, analyzing the contrasts of the significant aspects and the uniqueness and unrepeatability of heuristic learning. For this purpose, an in-depth review of the scientific literature was conducted, highlighting the main critical points of the approach, also defined as nonlinear, with the consequent elaboration of operational proposals for the various macro-families of sports.

Depue & Morrone-Strupinsky's (D&M-S's) model of affiliation meets the criteria advanced for the definition of behavior systems and endophenotypes. We argue that its application in psychiatry could be useful for identifying a biological pathophysiology common to a variety of conditions that are currently classified in very different categories of psychiatric nosography, including autism, schizoid personality, primary psychopathy, and dismissing attachment.
