All Eyes on Me : Behaving as Soloist in Duo Performances Leads to Increased Body Movements and Attracts Observers’ Visual Attention

2020

Duo musicians exhibit a broad variety of bodily gestures, but it is unclear how soloists’ and accompanists’ movements differ and to what extent they attract observers’ visual attention. In Experiment 1, seven musical duos’ body movements were tracked while they performed two pieces in two different conditions. In a congruent condition, soloist and accompanist behaved according to their expected musical roles; in an incongruent condition, the soloist behaved as accompanist and vice versa. Results revealed that behaving as soloist, regardless of the condition, led to more, smoother, and faster head and shoulder movements over a larger area than behaving as accompanist. Moreover, accompanists …

Communicating through ancillary gestures: Exploring effects on coperformers and audiences

2020

Musicians make elaborate movements while performing, often using gestures that might seem extraneous. To explore these movements, we motion-captured and audio-recorded different pairings of clarinetists and pianists performing Brahms’ Clarinet Sonata No. 1 with two manipulations: (a) allowing the performers full vs. no visual feedback, and (b) allowing the performers full vs. partial auditory feedback (i.e., the clarinetist could not hear the pianist). We found that observer ratings of audio–visual point-light renditions discriminated between manipulations and refined this insight through subsequent audio-alone and visual-alone experiments, providing an understanding of each modality’s cont…

RIED. Revista iberoamericana de educación a distancia

2015

Los Massive Online Open Courses (MOOC) son una modalidad de formación virtual que está ya presente en el panorama educativo actual y que responde a una concepción determinada de e-learning. Las universidades están integrando como parte de su oferta formativa este tipo de formación o, al menos, se está debatiendo si se integra o no. Ante esto, se hace necesario calibrar cuáles deben ser sus características con el fin de configurar un tipo de formación virtual de calidad. Se considera que son necesarios instrumentos que avalen la calidad de los MOOC desde diferentes perspectivas, en este caso la pedagógica, ya que de ello dependerá el éxito y la consolidación de este tipo de e-learning. El ob…

Intrinsic spin-orbit interaction in diffusive normal wire Josephson weak links: Supercurrent and density of states

2016

We study the effect of the intrinsic (Rashba or Dresselhaus) spin-orbit interaction in superconductor–nanowire–superconductor (SNS) weak links in the presence of a spin-splitting field that can result either from an intrinsic exchange field or the Zeeman effect of an applied field. We solve the full nonlinear Usadel equations numerically [The code used for calculating the results in this paper is available in https://github.com/wompo/Usadel-for-nanowires] and analyze the resulting supercurrent through the weak link and the behavior of the density of states in the center of the wire. We point out how the presence of the spin-orbit interaction gives rise to a long-range spin triplet supercurr…

Content Domain and Language Competence in Computer-mediated Conversation for Learning

2012

This study addresses the issue of interactional dominance in Teletandem conversations, in which two speakers communicate via video calls and chat and alternatively use their L2, the latter being the native language of the interlocutor. In particular, the research focuses on the impact of language competence (native/non-native) and content expertise (minus/plus familiarity with the topic at hand) on the role assumed by each interlocutor in structuring conversation. The data consists of 3 hours of computer-mediated recorded and transcribed conversations during 3 meetings: meeting 1 comprises free discussion for mutual introduction; meeting 2 is a discussion in English of a topic chosen by the…

A Navigation and Augmented Reality System for Visually Impaired People

2021

In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…

The Integration of Social and Neural Synchrony : A Case for Ecologically-Valid Research Using MEG Neuroimaging

2021

The recent decade has seen a shift from artificial and environmentally-deprived experiments in neuroscience to real-life studies on multiple brains in interaction, coordination and synchrony. In these new interpersonal synchrony experiments, there has been a growing trend to employ naturalistic social interactions to evaluate mechanisms underlying synchronous neuronal communication. Here, we emphasize the importance of integrating the assessment of neural synchrony with measurement of non-verbal behavioral synchrony as expressed in various social contexts: relaxed social interactions, planning a joint pleasurable activity, conflict discussion, invocation of trauma, or support giving, and as…
