Causal brain-heart information transfer during visual emotional elicitation in healthy subjects: Preliminary evaluations and future perspectives
2017
Complex heartbeat dynamics is known to reflect subject's emotional state, thanks to numerous links to brain cortical and subcortical regions. Likewise, specific brain regions are deeply involved in vagally-mediated emotional processing and regulation. Nevertheless, although the brain-heart interplay has been studied during visual emotion elicitation, directional interactions have not been investigated so far. To fill this gap, in this study we investigate brain-heart dynamics during emotional elicitation in healthy subjects through measures of Granger causality (GC) between the two physiological systems. Data were gathered from 22 healthy volunteers who underwent pleasant/ unpleasant affect…
Embodied responses to musical experience detected by human bio-feedback brain features in a geminoid augmented architecture
2018
Abstract This paper presents the conceptual framework for a study of musical experience and the associated architecture centred on Human-Humanoid Interaction (HHI). On the grounds of the theoretical and experimental literature on the biological foundation of music, the grammar of music perception and the perception and feeling of emotions in music hearing, we argue that music cognition is specific and that it is realized by a cognitive capacity for music that consists of conceptual and affective constituents. We discuss the relationship between such constituents that enables understanding, that is extracting meaning from music at the different levels of the organization of sounds that are f…
Regional Susceptibility in VCD Spectra to Dynamic Molecular Motions
2018
Experimental and theoretical studies of the vibrational circular dichroism (VCD) spectrum of 3-methyl-1-(methyldiphenlsilyl)-1-phenylbutan-1-ol, whose absolute configuration is key to elucidating the Brook rearrangement of tertiary benzylic α-hydroxylsilanes, are presented. It is found that the entire OH-bending region in this spectrum—a region that provides important marker bands—cannot be reproduced at all by standard theoretical approaches even though other regions are well described. Using a novel approach to disentangle contributions to the rotational strength of these bands, internal coordinates are identified that critically influence the appearance of this part of the spectrum. We s…
Bidimensionalidad de las emociones en deporte: construcción y validación de un instrumento de evaluación
2013
El presente trabajo tiene como objetivo la descripción de las evidencias de validez de constructo y la consistencia interna del “Instrumento de Emociones para la Competición Deportiva” (INECOD), instrumento de nueva creación que evalúa la percepción de las dimensiones fisiológica y cognitiva de las emociones durante la competición. Utilizando una muestra de 411 deportistas de 9 disciplinas, se obtiene una estructura factorial de tres dimensiones (afecto positivo, afecto negativo y ansiedad) en las dos subescalas. Los resultados confirman las evidencias de validez de constructo (Varianza explicada de 59,8% y 62,3%) y fiabilidad (entre α=0,538 y 0,822) presentando un instrumento que puede ser…
Sposoby vyraženiâ čuvstv i èmocij v Internet-obŝenii
2017
Język komunikacji w Internecie zbliżony jest do języka potocznego i charakteryzuje się dużą emocjonalnością. Internauci ośmieleni anonimowością w Sieci chętnie dzielą się swoimi uczuciami, wzburzeniem, zachwytem, radością i gniewem z innymi użytkownikami. Jak wiadomo, w odbiorze informacji najważniejszą rolę gra mimika oraz ton głosu. W komunikacji internetowej brak jest tak ważnego kanału wizualnego, więc internauci zmuszeni są przekazywać emocje innymi sposobami. Najczęściej wykorzystywane są przez nich znaki graficzne, czyli emotikony. Innymi często stosowanymi zabiegami są: zwielokrotnienie znaków interpunkcyjnych i liter, skandowanie (tj. dzielenie wyrazu na sylaby) oraz akcent frazowy…
An Intra-Subject Approach Based on the Application of HMM to Predict Concentration in Educational Contexts from Nonintrusive Physiological Signals in…
2021
Previous research has proven the strong influence of emotions on student engagement and motivation. Therefore, emotion recognition is becoming very relevant in educational scenarios, but there is no standard method for predicting students’ affects. However, physiological signals have been widely used in educational contexts. Some physiological signals have shown a high accuracy in detecting emotions because they reflect spontaneous affect-related information, which is fresh and does not require additional control or interpretation. Most proposed works use measuring equipment for which applicability in real-world scenarios is limited because of its high cost and intrusiveness. To tackle this…

Emotions and Autonomy in Foreign Language Learning at University
2018
<div> <p>This article explores the role of emotions in foreign language learning at university level. Drawing on the recent literature regarding the affective dimension in language learning, it illustrates the ways in which students experience emotions in foreign language learning. Particular emphasis is given to the way in which students’ emotions, both positive and negative, emerge and change during their learning process. The article presents a study conducted among university students learning English in a co-directed and autonomy-inspired environment. Following a qualitative approach, students’ emotional expression was investigated, by means of individual advising sessions …
Remote Photoplethysmography for Evaluation of Cutaneous Sensory Nerve Fiber Function
2021
About 2% of the world’s population suffers from small nerve fiber dysfunction, neuropathy, which can result in severe pain. This condition is caused by damage to the small nerve fibers and its assessment is challenging, due to the lack of simple and objective diagnostic techniques. The present study aimed to develop a contactless photoplethysmography system using simple instrumentation, for objective and non-invasive assessment of small cutaneous sensory nerve fiber function. The approach is based on the use of contactless photoplethysmography for the characterization of skin flowmotions and topical heating evoked vasomotor responses. The feasibility of the technique was evaluated on volunt…
