Abstract

To be published in "Perception, Representations, Image, Sound, Music, Revised papers of the CMMR2019"; International audience; This article describes a listening experiment based on elicitation interviews that aims at describing the conscious experience of a subject submitted to a perceptual stimulation. As opposed to traditional listening experiments in which subjects are generally influenced by closed or suggestive questions and limited to predefined, forced choices, elicitation interviews make it possible to get a deeper insight into the listener's perception, in particular to the pre-reflexive content of the conscious experiences. Inspired by previous elicitation interviews during which subjects passively listened to sounds, this experience is based on an active task during which the subjects were asked to reproduce a sound with a stylus on a graphic tablet that controlled a synthesis model. The reproduction was followed by an elicitation interview. The trace of the graphic gesture as well as the answers recorded during the interview were then analyzed. Results revealed that the subjects varied their focus towards both the evoked sound source, and intrinsic sound properties and also described their sensations induced by the experience.

Abstract

International audience; Designing a feedback that helps participants to achieve higher performances is an important concern in brain-computer interface (BCI) research. In a pilot study, we demonstrate how a congruent auditory feedback could improve classification in a electroencephalography (EEG) motor imagery BCI. This is a promising result for creating alternate feedback modality.

Abstract

International audience; We explored possibilities to increase motor imagery (MI) BCI performance by implementing Flow theory. According to this theory, by adapting the task difficulty to one's skills and making engaging content, one can reach a state of flow, i.e., to be fully immersed in a task, forgetting about the self and the environment, and thus reaching higher performance rates [1]. In this experiment, to evoke the state of flow, music was played in the background, the BCI task was playful (a video game), and the difficulty was adapted in real-time according to user performance (classifier output). Subjects reported to have been perturbed by the rhythm of the music which did not follow their imagined movement [2]. This inspired us to explore the benefits of a task-related (congruent) and synchronised audio feedback which would comply with the user's imagined movements. Congruent visual environment in MI BCI has been researched in virtual reality, giving a sense of body ownership illusion, and showed to be more robust and improve performance [3]. On the other hand, the effects of a congruent audio environment, have not yet been explicitly explored in BCI. We investigate the potential of an audio congruent to the task, tackling the sensori illusion of presence by providing realistic audio feedback using a synthesizer from [4]. We present preliminary results to show the benefits of a congruent, audio MI feedback of feet as opposed to no congruent feedback using abstract sound. We found a significant difference (p < 0.05) in classification accuracy when a binary classifier was trained offline separately on the "congruent" and "non-congruent" runs (respectively 66.1%, SD: 7.45 and 63.9% SD: 7.8, 10-fold cross-validation) [5].

Abstract

Ce travail part de l'observation phénoménologique du caractère complexe et versatile de l'expérience consciente, à chaque instant. Cette flexibilité (ou versatilité) de l'expérience consciente a amené les psychologues et les philosophes à penser celle-ci comme un flux et non comme un état. Dans ce travail, un questionnaire d'évaluation de la fluidité de la conscience (EQFC), comprenant 17 items, a été créé en utilisant des entretiens phénoménologiques expérientiels en groupe. ll a été ensuite évalué : a) dans une population de sujets sains ; b) chez des doctorants à la suite d'un stage d'explicitation de l'expérience consciente (méthode introspective) ; et c) chez quelques patients à l'issue d'hypnothérapie. La validation interne (symétrie, aplatissement, coefficient alpha de Cronbach) est très satisfaisante. Il a été possible de mettre en évidence quatre dimensions dans ce test : disponibilité à soi et à l'environnement, « lâcher prise » proprement dit, relative passivité face au monde, et acceptation du changement. Par ailleurs, il a été comparé au test FFMQ (Five Facets Mindfulness Questionnaire) avec lequel il est partiellement corrélé. Les résultats montrent que la flexibilité de la conscience n'est pas égale chez tous les sujets et que l'hypnothérapie et les méthodes introspectives augmentent la fluidité de la conscience, telle que mesurée par le test EQFC. This work starts from the phenomenological observation of the complex and versatile character of conscious experience, at every moment. This flexibility (or versatility) of conscious experience has led psychologists and philosophers to think of it as a flow and not as a state. In this work, a 17-item Conscientious Fluid Assessment Questionnaire (EQFC) was created using experiential phenomenological interviews. It was then evaluated: a) in a population of healthy subjects; b) in doctoral students following an internship of explicit conscious experience (introspective method) and; c) in some patients at the end of hypnotherapy. The internal validation (symmetry, flattening, Cronbach's alpha coefficient) is very satisfactory. It was possible to highlight 4 dimensions in this test: self and environmental availability, "letting go" itself, relative passivity to the world, and acceptance of change. Moreover, it has been compared to the Five Facets Mindfulness Questionnaire (FFMQ) with which it is partially correlated. The results show that the flexibility of consciousness is not equal in all subjects and that hypnotherapy and introspective methods increase the fluidity of consciousness, as measured by the EQFC test.
