Exploring relationships between audio features and emotion in music

2009

In this paper, we present an analysis of the associations between emotion categories and audio features automatically extracted from raw audio data. This work is based on 110 excerpts from film soundtracks evaluated by 116 listeners. This data is annotated with 5 basic emotions (fear, anger, happiness, sadness, tenderness) on a 7 points scale. Exploiting state-of-the-art Music Information Retrieval (MIR) techniques, we extract audio features of different kind: timbral, rhythmic and tonal. Among others we also compute estimations of dissonance, mode, onset rate and loudness. We study statistical relations between audio descriptors and emotion categories confirming results from psychological …

Interoception moderates the relation between alexithymia and risky-choices in a framing task: A proposal of two-stage model of decision-making.

2021

Decision-making depends on the context (frame) in which questions and alternatives are presented. Moreover, research has showed that the ability to detect bodily sensations (interoception) and being able to attribute these changes to emotions correctly (alexithymia) influence how we make decisions. The aim of the present research was to study how interoception and alexithymia might affect the Framing effect (FE), a cognitive bias closely related to emotional system. 42 healthy participants completed the Risky-choice Framing task and their interoception and alexithymia levels were measured. Results showed that the participants were more risk-taking under the negative frames in comparison to …

Emotional arousal modulates the encoding of crime-related details and corresponding physiological responses in the Concealed Information Test

2011

Previous studies demonstrated that concealed crime-related memories can be validly identified using the Concealed Information Test (CIT). However, its field applicability is still debated, and it is specifically unknown how emotional arousal during a crime would influence CIT results. In the current study, emotional arousal during a mock crime and the time delay between mock crime and CIT examination were manipulated. At the immediate and the delayed CIT occasion, central crime details were better remembered than peripheral ones and enhanced emotional arousal further reduced memory for peripheral information. Electrodermal, respiratory, and cardiovascular responses to central crime details …

Some Necessary Revisions of the Neuronal Model Concept of the Orienting Response

1978

Sokolov's neural trace model as well as his entropy model of the orienting response are examined. Both seem inadequate for empirical and theoretical reasons. The role of the relevance aspect of a stimulus is stressed. It is proposed to consider the information transmitted by a stimulus as in some way being weighted by the relevance of the context to which it belongs. It is furthermore proposed to restrict the neural trace concept to the physical properties of the stimulus. Major theoretical gain is achieved by viewing information content of a stimulus and its physical properties independently and by breaking the motivation determining the strength of an orienting response into a situation-s…

The development of aesthetic responses to music and their underlying neural and psychological mechanisms.

2011

In the field of psychology, the first studies in experimental aesthetics were conducted approximately 140 years ago. Since then, research has mainly concentrated on aesthetic responses to visual art. Both the aesthetic experience of music and, especially, its development have received rather limited attention. Moreover, until now, very little attention has been paid to the investigation of the aesthetic experience of music using neuroscientific methods. Aesthetic experiences are multidimensional and include inter alia sensory, perceptual, affective, and cognitive components. Aesthetic processes are usually experienced as pleasing and rewarding and are, thus, important and valuable experienc…

The Neural Bases of Event Monitoring across Domains: a Simultaneous ERP-fMRI Study.

2017

The ability to check and evaluate the environment over time with the aim to detect the occurrence of target stimuli is supported by sustained/tonic as well as transient/phasic control processes, which overall might be referred to as event monitoring. The neural underpinning of sustained attentional control processes involves a fronto-parietal network. However, it has not been well-defined yet whether this cortical circuit acts irrespective of the specific material to be monitored and whether this mediates sustained as well as transient monitoring processes. In the current study, the functional activity of brain during an event monitoring task was investigated and compared between two cognit…

An artistic approach to neurofeedback for emotion regulation

2019

AbstractNeurofeedback has been shown to be a promising tool for learning to regulate one’s own emotions in healthy populations and in neuropsychiatric disorders. While it has been suggested that neurofeedback performance improves when sensory feedback is related to the pathology under consideration, it is still difficult to represent in real time a proper feedback representative of our emotional state. Since emotion is a central part of people’s dealings with artworks, we have initiated a collaboration between neuroscientists and artists to develop a visual representation of emotions that can be used in neurofeedback experiences. As a result of this collaboration, emotions were represented …

Validation of the Virtual Reality Neuroscience Questionnaire: Maximum Duration of Immersive Virtual Reality Sessions Without the Presence of Pertinen…

2019

Research suggests that the duration of a VR session modulates the presence and intensity of VRISE, but there are no suggestions regarding the appropriate maximum duration of VR sessions. The implementation of high-end VR HMDs in conjunction with ergonomic VR software seems to mitigate the presence of VRISE substantially. However, a brief tool does not currently exist to appraise and report both the quality of software features and VRISE intensity quantitatively. The VRNQ was developed to assess the quality of VR software in terms of user experience, game mechanics, in-game assistance, and VRISE. Forty participants aged between 28 and 43 years were recruited (18 gamers and 22 non-gamers) for…
