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…
Sonification of Emotion : Strategies for Continuous Display of Arousal and Valence
2013
Sonification is an interdisciplinary field of research broadly interested in the use of sound to convey information. A fundamental attribute of sound is its ability to evoke emotion, but the display of emotion as a continuous data type has not yet received adequate attention. This paper motivates the use of sonification for display of emotion in affective computing, and as a means of targeting mechanisms of emotion elicitation in music. Environmental sound and music are presented as two possible sources for non-verbal auditory emotion elicitation, each with specific determinants and available features. The review concludes that the auditory-cognitive mechanisms of brain-stem reflex and emot…
Il primo innamoramento vissuto dagli adolescenti palermitani
2012
In questo contributo, è presentato il processo di una ricerca avviata nel 2010. Il problema dell'educazione affettiva degli adolescenti emerge quando si verifica il primo innamoramento. Questo fenomeno mostra come l'educazione dei sentimenti fino ad ora si è sviluppata e presuppone ciò che è necessario per completarlo. Volevamo indagare sul modo in cui gli adolescenti palermitani vivono il primo innamoramento e sui cambiamenti che questo fenomeno provoca negli adolescenti che lo vivono e nel loro ambiente sociale immediato. Si è utilizzato uno strumento (l'intervista) che non va abbastanza in profondità, ma si limita a rilevare la sincerità delle risposte. Dopo aver descritto il modo in cui…
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…
On the Convergence of Affective and Persuasive Technologies in Computer-Mediated Health-Care Systems
2015
This paper offers a portrayal of how affective computing and persuasive technologies can converge into an effective tool for interfacing biomedical engineering with behavioral sciences and medicine. We describe the characteristics, features, applications, present state of the art, perspectives, and trends of both streams of research. In particular, these streams are analyzed in light of the potential contribution of their convergence for improving computer-mediated health-care systems, by facilitating the modification of patients’ attitudes and behaviors, such as engagement and compliance. We propose a framework for future research in this emerging area, highlighting how key constructs and …
Music video covers, minoritised languages, and affective investments in the space of YouTube
2017
AbstractWhile interest in affective processes has led to an affective turn in cultural studies, in sociolinguistics this perspective has been given less attention. This study takes up the ‘lens of affect’ and directs it on two cases exemplifying the circulation of minoritised languages in new media spaces: music video covers from two minority-language contexts, Irish and Sámi, uploaded on YouTube. Combining recent theorising on affect with insights from sociolinguistic research, the study investigates how the YouTube users’ affective investments contribute to a (re)evaluation of the two minoritised languages, their speakers, and the related ethnic/national belongings, and how these investme…
Physical multimorbidity predicts the onset and persistence of anxiety: A prospective analysis of the Irish Longitudinal Study on Ageing.
2022
Background: The aims of the present study were to examine prospective associations of multimorbidity (i.e., >= 2 chronic conditions) at baseline with incident and persistent anxiety over a two-year follow-up period among Irish older adults, and to quantify the extent to which sleep, pain, and disability mediate the multimorbidity-anxiety relationship.& nbsp;Methods: Data from The Irish Longitudinal Study on Aging (TILDA) conducted between 2009 and 2011 with a follow-up after two years were analyzed. Anxiety referred to score >=& nbsp;8 on the anxiety section of the Hospital Anxiety and Depression Scale. Lifetime diagnosis of 14 chronic conditions was obtained. Outcomes were in…
Depressive symptoms in late life: a 10-year follow-up
2003
The objectives of this study were to describe the changes occurring in depressive symptomatology over a 10-year period among 75-year-old residents of Jyväskylä, Finland. It also addressed the question of whether the mood disturbances detected were a permanent phenomenon or whether they had a more episodic nature. In addition, various associations with and predictors of low mood were studied. Depressive symptoms were screened with the Center for Epidemiologic Studies Depression Scale (CES-D).The cut-off point of 16 was used to distinguish depressed individuals from those classified as non-depressed. A baseline study was carried out in 1989 (n = 337). A 5-year follow-up was carried out with t…
Emotional and cognitive adjustment in abused children
1994
Research on the impact of maltreatment on children has increased in the last years, as there is a need to design appropriate treatment strategies. Social, cognitive, and emotional areas may be affected in these children. This research is aimed to study the psychological functioning of child victims, particularly in their emotional and cognitive adjustment. Nineteen children (10.3 years old) with case histories of at least 2 years of physical and emotional parental abuse and a group of 26 nonmaltreated children (9.4 years old) matched in socio-economic characteristics and coming from the same community area were compared in depressive symptomatology and attributional style by using the stand…
The effects of age and emotional valence on recognition memory: An ex-Gaussian components analysis
2014
[EN] The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex-Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The tau parameter, often related to attention in the literature, was smaller for young than …
