A number of theories about the origins of musicality have incorporated biological and social perspectives. Darwin argued that musicality evolved by sexual selection, functioning as a courtship display in reproductive partner choice. Darwin did not regard musicality as a sexually dimorphic trait, paralleling evidence that both sexes produce and enjoy music. A novel research strand examines the effect of musicality on sexual attraction by acknowledging the importance of facial attractiveness. We previously demonstrated that music varying in emotional content increases the (...) perceived attractiveness and dating desirability of opposite-sex faces only in females, compared to a silent control condition. Here, we built upon this approach by presenting the person depicted (target) as the performer of the music (prime), thus establishing a direct link. We hypothesized that musical priming would increase sexual attraction, with high-arousing music inducing the largest effect. Musical primes (25 s, piano solo music) varied in arousal and pleasantness, and targets were photos of other-sex faces of average attractiveness and with neutral expressions (2 s). Participants were 35 females and 23 males (heterosexual psychology students, single, and no hormonal contraception use) matched for musical background, mood, and liking for the music used in the experiment. After musical priming, females’ ratings of attractiveness and dating desirability increased significantly. In males, only dating desirability was significantly increased by musical priming. No specific effects of music-induced pleasantness and arousal were observed. Our results, together with other recent empirical evidence, corroborate the sexual selection hypothesis for the evolution of human musicality. (shrink)

As a cornerstone of public health, epidemiology has lately undergone substantial changes enabled by, among other factors, the use of biobank infrastructures. In biobank-related research, the return of results to participants constitutes an important and complex ethical question. In this study, we qualitatively investigated how individuals perceive the results returned following their participation in cohort studies with biobanks. In our semi-structured interviews with 31 participants of two such German studies, we observed that some participants overestimate the nature of the personal (...) information they will receive from the study. Although this misestimation does not seem to jeopardize the validity of the consent provided at recruitment, it may still represent a threat for participants’ trust in research and thus their long-term commitment, crucial for such studies. We argue that such misestimation may have ethical consequences on the principles guiding the reflection on the return of results in biobank research, i.e. autonomy, beneficence, non-maleficence and reciprocity. We suggest that shifting from the idea of directly benefiting participants through the return of research results could help focusing on benefiting society as a whole, thereby increasing research trustworthiness of population-based studies using biobanks.

A short number of entries in Andalusi biographical sources are devoted to pious women. These women are usually described as practising the recitation of the Quran, giving alms, leading a retired life and fasting. Together with other texts, these biographies draw a picture in which a secluded life and fasting became the privileged characteristics of religious piety among Andalusi women. Fasting, in particular, could be used as a means of going beyond the limits imposed on women by Muslim orthopraxis.

Resumen: Este trabajo tiene como objetivo mostrar que el análisis sistémico aplicado a los espacios locales facilita la generación de propuestas para su desarrollo integral en el ámbito de la sostenibilidad. Los territorios están compuestos por elementos físicos y sociales que se interrelacionan y generan productos que los benefician o perjudican. Estos recursos pueden ser explotados o encontrarse ociosos por falta de actores que los desarrollen. Reaccionan ante las acciones internas y externas tanto humanas como naturales, entre las que se (...) encuentran las políticas para el desarrollo local. Para que estas políticas sean eficientes, necesitan estudios integrales que contengan una información que muestre las deficiencias estructurales, relacionales y funcionales del territorio y, con esta información, adoptar las medidas que las corrijan. Este estudio muestra que el análisis sistémico es una herramienta útil para la elaboración de estas políticas.This paper shows how system analysis applied to local spaces facilitate the generation of proposals for integral development in the field of sustainability. Regions are composed of physical and social components generating products that benefit or harm themselves. These resources can be exploited or remained idle for lack of actors to develop them. They react to internal and external actions, both human and natural. Among these actions are the policies for local development. For these policies to be efficient, they need comprehensive studies that contain information that shows the structural, relational and functional deficiencies of the territory and, with this information, adopt the necessary political actions to correct them. This study supports system analysis as an information tool for policy-making. (shrink)

Comparing mortuary rituals across 57 representative cultures extracted from the Human Relations Area Files, this paper demonstrates that kin of the deceased engage in behaviours to prepare the deceased for disposal that entail close and often prolonged contact with the contaminating corpse. At first glance, such practices are costly and lack obvious payoffs. Building on prior functionalist approaches, we present an explanation of corpse treatment that takes account of the unique adaptive challenges entailed by the death of a loved one. (...) We propose that intimate contact with the corpse provides the bereaved with extensive veridical cues of death, thereby facilitating acceleration of a grieving process that serves to recategorize the deceased as no longer a relationship partner, opening the door to relationship replacement and a return to social functioning. The benefits of exposure to such cues are tempered by the costs of exposure to cues of disease risk, a balance that in part explains the relative rarity of highly invasive mortuary practices that exacerbate the latter factor. We conclude by discussing implications of our model for contemporary mortuary practices in the developed world. (shrink)

L’activité créatrice du design industriel est l’héritière directe du concept grec du τέχνη, et de la notion romaine d’ ars. Au contraire des Beaux-Arts, le design n’a jamais complètement renoncé à sa dimension fonctionnelle, et sa créativité s’est déployée au service des objets qui nous entourent. Victor Papaneck a lancé en 1971, dans son libre Design for the Real World, un appel à l’attention des designers en leur rappelant leur responsabilité sociale et en exigeant d’eux une attitude respectueuse envers l’environnement. (...) Cependant, aujourd’hui les choses ont beaucoup changé, tant à un niveau conceptuel que technologique. Pour cela il est nécessaire d’analyser, à partir des produits concrets des designers au xxi e siècle, la nouvelle orientation de l’ecodesign et d’approfondir les lignes d’action du design actuel qui maintiennent un engagement éthique avec la société : inclusive design/universal design et design pour la nécessité/ Design Takes of Risk.

Based on studies with infants, we expand on Stoffregen & Bardy's explanation of perceptual motor errors, given the global array. Information pick-up from the global array is not sufficient without adequate exploratory movements and learning to support perceptually guided activity.

There is considerable evidence that beliefs in supernatural punishment decrease self-interested behavior and increase cooperation amongst group members. To date, research has largely focused on beliefs concerning omniscient moralistic gods in large-scale societies. While there is an abundance of ethnographic accounts documenting fear of supernatural punishment, there is a dearth of systematic cross-cultural comparative quantitative evidence as to whether belief in supernatural agents with limited powers in small-scale societies also exert these effects. Here, we examine information extracted from the Human (...) Relations Area Files on cultural discourse about the recently deceased, local ancestor spirits, and mortuary practices across 57 representative cultures. We find evidence that in traditional small-scale societies ancestor spirits are commonly believed to be capable of inflicting harm, with many attendant practices aimed at mitigating this danger. However, such beliefs do not appear to promote cooperation, as ancestor spirits seem to be concerned with interactions between themselves and the living, and to prioritize their own welfare. Many attendant practices are inconsistent even with bipartite cooperation with ancestors that could be viewed as a model for other relationships. The broader implications of this research for the cultural evolution of religion are discussed. (shrink)

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D (...) ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions. (shrink)

Processing and recognizing facial expressions are key factors in human social interaction. Past research suggests that individuals with autism spectrum disorder present difficulties to decode facial expressions. Those difficulties are notably attributed to altered strategies in the visual scanning of expressive faces. Numerous studies have demonstrated the multiple benefits of exposure to pet dogs and service dogs on the interaction skills and psychosocial development of children with ASD. However, no study has investigated if those benefits also extend to the processing (...) of facial expressions. The aim of this study was to investigate if having a service dog had an influence on facial expression processing skills of children with ASD. Two groups of 15 children with ASD, with and without a service dog, were compared using a facial expression recognition computer task while their ocular movements were measured using an eye-tracker. While the two groups did not differ in their accuracy and reaction time, results highlighted that children with ASD owning a service dog directed less attention toward areas that were not relevant to facial expression processing. They also displayed a more differentiated scanning of relevant facial features according to the displayed emotion. Results from the present study suggest that having a service dog and interacting with it on a daily basis may promote the development of specific visual exploration strategies for the processing of human faces.

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

ABSTRACT:We examine supervisor-subordinate agreement regarding perceptions of the supervisor’s ethical leadership and its relationship to organizational deviance. We find that, on average, supervisors rate themselves more favorably on ethical leadership compared to how followers rate them. In addition, polynomial regression results reveal that unit-level organizational deviance is higher when there is agreement about lower levels of ethical leadership, and disagreement when supervisors rate themselves higher on ethical leadership than subordinates’ ratings of the supervisors. Finally, drawing on social influence theories, we (...) look at antecedents of agreement and find that supervisors’ beliefs about themselves and others are associated with self-other agreement on ethical leadership.
