Difficulty engaging in reciprocal social interactions is a core characteristic of autism spectrum disorder. The mechanisms supporting effective dynamic real-time social exchanges are not yet well understood. This proof-of-concept hyperscanning electroencephalography study examined neural synchrony as the mechanism supporting interpersonal social interaction in 34 adolescents with autism spectrum disorder, age 10–16 years, paired with neurotypical confederates of similar age. The degree of brain-to-brain neural synchrony was quantified at temporo-parietal scalp locations as the circular correlation of oscillatory amplitudes in theta, alpha, (...) and beta frequency bands while the participants engaged in a friendly conversation. In line with the hypotheses, interpersonal neural synchrony was significantly greater during the social interaction compared to the baseline. Lower levels of synchrony were associated with increased behavioral symptoms of social difficulties. With regard to sex differences, we found evidence for stronger interpersonal neural synchrony during conversation than baseline in females with autism, but not in male participants, for whom such condition differences did not reach statistical significance. This study established the feasibility of hyperscanning during real-time social interactions as an informative approach to examine social competence in autism, demonstrated that neural coordination of activity between the interacting brains may contribute to social behavior, and offered new insights into sex-related variability in social functioning in individuals with autism spectrum disorders.

State concussion laws and sport-league policies are important tools for protecting public health, but also present implementation challenges. Both state laws and league policies often require athletes provide written acknowledgement of having received concussion-related information and/or of their responsibility to report concussion-related symptoms. This paper examines these requirements in two ways: an analysis of the variation in state laws and sport-league policies and a study of their effects in a cohort of collegiate football players.

This study examined the extent to which concussion management plans at National Collegiate Athletic Association member schools were in line with NCAA Concussion Policy and best practice recommendations in absence of any process to ensure compliance. Most schools' concussion management plans were in compliance with 3 or 4 of the NCAA's 4 required components. Annual athlete education and acknowledgement was the requirement least often included, representing an area for improvement. Further, schools tended to more often include best practices that were (...) more medically-oriented, compared to best practices that were less medical in nature. (shrink)

Cognitive reappraisal is an important emotion regulation strategy that shows considerable developmental change in its use and effectiveness. This paper presents a systematic review of the evidence base regarding the development of cognitive reappraisal from early childhood through adolescence and provides methodological recommendations for future research. We searched Scopus, PsycINFO, and ERIC for empirical papers measuring cognitive reappraisal in normative samples of children and youth between the ages of 3 and 18 years published in peer-reviewed journals through August 9th, 2018. (...) We identified 118 studies that met our inclusion criteria. We first present a quantitative review of the methodologies used to investigate cognitive reappraisal in children and adolescents, with attention to variations in methodologies by the sample age range. We then present a qualitative review of findings with attention to: the age at which children begin to effectively use cognitive reappraisal to regulate their emotions, and developmental changes in cognitive reappraisal from early childhood through adolescence. We consider how methodological differences may contribute to inconsistencies in findings, highlight gaps in the literature that remain to be addressed, and make recommendations for future directions.

ABSTRACT There is limited guidance about whether and how to provide psychological assessment results to research participants. This paper considers several ethical challenges associated with offering individual research results in psychological assessment research. Additionally, the process used to return individual results within a study examining neurodevelopmental effects of anesthesia exposure in children and adolescents is described. Almost all participants requested to know if results were concerning; however, only around a third of those with concerning findings sought additional feedback. Ongoing research (...) and guidance are necessary to establish evidence-based practices and manage challenges that may emerge when disclosing such results. (shrink)

There are several models of the use of geometric and feature cues in reorientation. The adaptive combination approach posits that people integrate cues with weights that depend on cue salience and learning, or, when discrepancies are large, they choose between cues based on these variables. In a new paradigm designed to evaluate integration and choice, disoriented participants attempted to return to a heading direction, in a trapezoidal enclosure in which feature and geometric cues both unambiguously specified a heading, but later (...) the feature was moved. With discrepancies greater than 90 degrees, participants choose geometry. With smaller discrepancies, integration appeared in three of five situations; otherwise, participants used geometry alone. Variation depended on direction of feature movement and whether the nearest corner was acute or obtuse. The results have implications for contrasting adaptive combination and modularity theory, and for future research, offering a new paradigm for reorientation research, and for testing cue integration more broadly.

Research on linguistic interaction suggests that two or more individuals can sometimes form adaptive and cohesive systems. We describe an “alignment system” as a loosely interconnected set of cognitive processes that facilitate social interactions. As a dynamic, multi-component system, it is responsive to higher-level cognitive states such as shared beliefs and intentions (those involving collective intentionality) but can also give rise to such shared cognitive states via bottom-up processes. As an example of putative group cognition we turn to transactive memory (...) and suggest how further research on alignment in these cases might reveal how such systems can be genuinely described as cognitive. Finally, we address a prominent critique of collective cognitive systems, arguing that there is much empirical and explanatory benefit to be gained from considering the possibility of group cognitive systems, especially in the context of small-group human interaction.

In the classroom, philosophers face not only the perennial problems of philosophy, but the problems of _teaching_ philosophy, and specifically the problems of teaching philosophy today: how to make philosophy interesting and relevant to students who are resistant to, or unfamiliar with, the discipline; how to bring classic texts to life within our current socio-cultural context; how to serve all students regardless of their abilities, backgrounds, or declared majors; how to sustain our discipline in light of support for more "vocational" (...) pursuits. In these essays, 24 of our most celebrated professors of philosophy offer perspectives on and solutions to these questions and more. Selected and introduced by three leaders in the world of philosophical education, the insights contained in this inspiring collection illuminate the challenges and possibilities of teaching the academy’s oldest discipline.

Contemporary approaches to adolescent development are framed by positive youth development models. A key outcome of these models is that healthy and positively developing youth are more likely to contribute to their family, schools, and communities. However, little work on contribution and its antecedents has been conducted with youth of color. As high achieving youth of color often become leaders in their communities, it is important to consider malleable predictors of contribution within this population. Therefore, through a cross-sectional design, we (...) examined the relations between youth critical reflection, hopeful future expectations, and mentoring relationship quality and youth contribution in a sample of 177 youth of color (60% Black, 40% Latinx) attending an afterschool college preparation program at six sites around the U.S. Results indicated that youth critical reflection, hopeful future expectations, and mentoring relationship quality significantly predicted contribution. Exploratory analyses suggested that these relations were significant for Black youth but not Latinx youth. Implications of these findings for future scholarship are discussed. (shrink)

Using semiotic and historical methods, the article recovers the ancient Russian concept of ‘state’, which appeared and gained a foothold in the Russian social and cultural space in the fourteen and fifteenth centuries. In the authors’ opinions, this content has determined the basic features for understanding the State in modern post-Soviet Russian society to date. Accordingly, it is important to reassemble the main conceptual threads in the ‘state’ concept during the epoch of Ivan the Terrible, the Muscovite Tsar, the epoch (...) when the ‘state’ concept gained a foothold in Russian political culture. To re-establish the content of the ‘state’ concept, a historical description, an etymological and comparative analysis of this concept, as well as content analysis of the first epistle from Tsar Ivan the Terrible to Duke Andrei Kurbsky were employed. As a result, it was possible to recover the aspects of the ‘state’ concept that continue to be reproduced in post-Soviet Russian culture and predetermine certain elements of modern Russia’s political outlook. This concerns the central role of the ‘sovereign ruler’ in the State, the ideal of the ideological unity, the State’s mission of mediation between man and God, the hierarchy of the State and the sacral role of the ruler at the peak of this hierarchy.

This article deals with the analysis of neo-mythological and pantheistic subjects in the works of Friedrich Nietzsche and Knut Hamsun. The analytical comparison of Nietzsche’s philosophical concepts and Hamsun’s literary psychologism is poised to find an underlying understanding of human nature at the confluence of ethics and aesthetics - of goods and beauty, of evil and ugly. A precise definition of the aesthetic categories “Apollonian” and “Dionysian” is carried out based on Nietzsche’s work “The Birth of Tragedy from the Spirit (...) of Music”. The relevance of the Dionysian culture’s phenomena is based on the Nietzschean belief in an Übermensch within the modern mindset. The concept of “Dionysus” finds its continuation in the postmodern philosophy of Georges Bataille and Maurice Blanchot, in such archaic emotional and aesthetic aspects of human essence as violence and sacrifice understood in an extremely abstract sense. The authors stress that modern culture’s interest in violence and sacrifice is rooted in Nietzsche’s idea of Dionysius in the meaning of one of the beginnings of any segment of European culture. The foundations for overcoming postmodernism in the 21st century and the subsequent development of aesthetic views can be found in an attempt to revise the foundation of European culture through rethinking the concept of Übermensch-Zarathustra-Dionysus.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Le terme platonisme est ambigu : il peut désigner soit le contenu de la philosophie de Platon, soit l’histoire de sa réception et de ses interprétations. C’est en suivant les méandres de cette seconde acception que Mauro Bonazzi (MB) propose une étude du platonisme dans un parcours allant de Speusippe jusqu’aux derniers diadoques de l’école d’Alexandrie. L’ouvrage, qui entre rapidement dans son objet, comporte quatre chapitres bien équilibrés : 1. « L’Académie antique » (p. 3-37) ; 2. « Plato...

When recalling autobiographical events, people not only retrieve event details but also the feelings they experienced. The current study examined whether people are able to consistently recall the intensity of past feelings associated with two consequential and negatively valenced events, i.e. the 9/11 attack (N = 769) and the COVID-19 pandemic (N = 726). By comparing experienced and recalled intensities of negative feelings, we discovered that people systematically recall a higher intensity of negative feelings than initially reported – overestimating the (...) intensity of past negative emotional experiences. The COVID-19 dataset also revealed that individuals who experienced greater improvement in emotional well-being displayed smaller biases in recalling their feelings. Across both datasets, the intensity of remembered feelings was correlated with initial feelings and current feelings, but the impact of the current feelings was stronger in the COVID-19 dataset than in the 9/11 dataset. Our results demonstrate that when recalling negative autobiographical events, people tend to overestimate the intensity of prior negative emotional experiences with their degree of bias influenced by current feelings and well-being.

We prove an effective version of the Lopez-Escobar theorem for continuous domains. Let $Mod(\tau )$ be the set of countable structures with universe $\omega $ in vocabulary $\tau $ topologized by the Scott topology. We show that an invariant set $X\subseteq Mod(\tau )$ is $\Pi ^0_\alpha $ in the Borel hierarchy of this topology if and only if it is definable by a $\Pi ^p_\alpha $ -formula, a positive $\Pi ^0_\alpha $ formula in the infinitary logic $L_{\omega _1\omega }$. As (...) a corollary of this result we obtain a new pullback theorem for positive computable embeddings: Let $\mathcal {K}$ be positively computably embeddable in $\mathcal {K}'$ by $\Phi $, then for every $\Pi ^p_\alpha $ formula $\xi $ in the vocabulary of $\mathcal {K}'$ there is a $\Pi ^p_\alpha $ formula $\xi ^{*}$ in the vocabulary of $\mathcal {K}$ such that for all $\mathcal {A}\in \mathcal {K}$, $\mathcal {A}\models \xi ^{*}$ if and only if $\Phi (\mathcal {A})\models \xi $. We use this to obtain new results on the possibility of positive computable embeddings into the class of linear orderings. (shrink)

Cet article propose la première publication complète d’un monument consacré par les Thespiens aux Muses dans leur sanctuaire au pied de l’Hélicon, dont les éléments constitutifs sont connus depuis le xixe s., et notamment depuis les fouilles de P. Jamot au Val des Muses. Les statues en bronze de petite taille des neuf Muses se dressaient sur une base en arc de cercle d’une ampleur de ca 10 m, placée dans un écrin architectural largement ouvert sur l’extérieur. Un nouveau lustre (...) est donné à ce groupe statuaire hellénistique exceptionnel à l’époque d’Auguste par la gravure, sous chacune des figures, d’une épigramme descriptive et érudite signée par le poète corinthien Honestos. Est ainsi conservé l’un des rares exemples archéologiques de recueil de poèmes décrivant des œuvres d’art figuré. L’analyse des épigrammes et l’observation détaillée des mortaises de fixation visibles à la face supérieure des blocs de la base permettent d’émettre des hypothèses sur les types utilisés pour la représentation des Muses, mais aussi d’assurer, au‑delà de tout doute, que les statues prenaient place au milieu d’ornements végétaux en bronze qui évoquaient le paysage du Val des Muses. La représentation de la nature comme élément non plus secondaire, mais essentiel d’un groupe sculpté correspond aux recherches nouvelles de la basse époque hellénistique. Faute de fouilles exhaustives du sanctuaire des Muses, l’emplacement du monument ne peut être déterminé avec certitude. Des lettres de remontage nous apprennent en revanche qu’il a été déplacé, peut‑être à l’époque où furent gravés les poèmes d’Honestos. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

Aim Facebook is an increasingly popular online social networking site. The purpose of this study was to describe the Facebook activity of residents and fellows and their opinions regarding the impact of Facebook on the doctor–patient relationship. Methods An anonymous questionnaire was emailed to 405 residents and fellows at the Rouen University Hospital, France, in October 2009. Results Of the 202 participants who returned the questionnaire (50%), 147 (73%) had a Facebook profile. Among responders, 138 (99%) displayed their real name (...) on their profile, 136 (97%) their birthdates, 128 (91%) a personal photograph, 83 (59%) their current university and 76 (55%) their current position. Default privacy settings were changed by 61% of users, more frequently if they were registered for >1 year (p=0.02). If a patient requested them as a ‘friend’, 152 (85%) participants would automatically decline the request, 26 (15%) would decide on an individual basis and none would automatically accept the request. Eighty-eight participants (48%) believed that the doctor–patient relationship would be altered if patients discovered that their doctor had a Facebook account, but 139 (76%) considered that it would change only if the patient had open access to their doctor's profile, independent of its content. Conclusions Residents and fellows frequently use Facebook and display personal information on their profiles. Insufficient privacy protection might have an impact the doctor–patient relationship.

BackgroundAlthough a large number of clinical trials on interventions demonstrating efficacy (or lack thereof) are conducted annually, much of this evidence is not accessible to scientists and clinicians.ObjectivesWe aimed to determine the publication rate of posttraumatic stress disorder (PTSD) trials that have been registered in clinical trial registries, and the factors associated with publication.MethodsTrials, completed on January 15, 2015, were identified via the US National Institutes of Health clinical trials registry, the European Union Clinical Trials Register and the WHO International (...) Clinical Trials Registry Platform. A systematic search for publications (published by the end of March 2018) related to each of the registered trials were then performed.ResultsFour hundred and thirty-eight of 1982 potentially eligible trials were included. Only 34% of interventional trials were registered prior to initiation, 9% were registered within 2 months of starting and 20% after trial completion. Of the 438 included trials, 72% had generated peer-reviewed publications, while an additional 7% had disseminated results in some other form (such as on the trial database), 26 months after trial completion. Randomisation of a trial was the only factor individually associated with publication, in logistic regression analysis (p < 0.001). Intervention type, university as sponsor and study registration prior to completion were factors that influenced the time to publication, using Cox regression (p < 0.001).ConclusionsThis study underscores the importance of timely and accurate publication and dissemination of trial results, in order to avoid the potential waste of resources and to ensure research integrity and patient safety. We suggest that authors and journal editors adhere to conditions set out by the International Committee of Medical Journal Editors and that more diligent data sharing is encouraged through prospective trial registration and trial reporting websites.

BackgroundPhysical activity is known to improve mental health, and is regarded as safe and desirable for uncomplicated pregnancy. In this novel study, we aim to evaluate whether there are associations between maternal physical activity during pregnancy and neonatal brain cortical development.MethodsForty-four mother/newborn dyads were included in this longitudinal study. Healthy pregnant women were recruited and their physical activity throughout pregnancy were documented using accelerometers worn for 3–7 days for each of the 6 time points at 4–10, ∼12, ∼18, ∼24, ∼30, (...) and ∼36 weeks of pregnancy. Average daily total steps and daily total activity count as well as daily minutes spent in sedentary/light/moderate/vigorous activity modes were extracted from the accelerometers for each time point. At ∼2 weeks of postnatal age, their newborns underwent an MRI examination of the brain without sedation, and 3D T1-weighted brain structural images were post-processed by the iBEAT2.0 software utilizing advanced deep learning approaches. Cortical surface maps were reconstructed from the segmented brain images and parcellated to 34 regions in each brain hemisphere, and mean cortical thickness for each region was computed for partial correlation analyses with physical activity measures, with appropriate multiple comparison corrections and potential confounders controlled.ResultsAt 4–10 weeks of pregnancy, mother’s daily total activity count positively correlated (FDR corrected P ≤ 0.05) with newborn’s cortical thickness in the left caudal middle frontal gyrus (rho = 0.48, P = 0.04), right medial orbital frontal gyrus (rho = 0.48, P = 0.04), and right transverse temporal gyrus (rho = 0.48, P = 0.04); mother’s daily time in moderate activity mode positively correlated with newborn’s cortical thickness in the right transverse temporal gyrus (rho = 0.53, P = 0.03). At ∼24 weeks of pregnancy, mother’s daily total activity count positively correlated (FDR corrected P ≤ 0.05) with newborn’s cortical thickness in the left (rho = 0.56, P = 0.02) and right isthmus cingulate gyrus (rho = 0.50, P = 0.05).ConclusionWe identified significant relationships between physical activity in healthy pregnant women during the 1st and 2nd trimester and brain cortical development in newborns. Higher maternal physical activity level is associated with greater neonatal brain cortical thickness, presumably indicating better cortical development. (shrink)
