Full textThe initial part of this work highlights specificities in the electrodermal activity (EDA), index of the sympathetic nervous system activity, in chronic pain patients. In a first experiment, the EDA recordings are performed at rest and during a series of pure innocuous tones. Non-depressed chronic pain patients present an increased EDA as compared to healthy participants. Regarding the frequency of spontaneous fluctuations (FSs), patients can be described as labile individuals. Depressed chronic pain patients do not demonstrate this effect. A second experiment shows that FSs emission is related to intense thoughts. However, if the occurence of the phenomenon is increased in patients, the underlying process is not fundamentally different in controls. A third experiment indicates that pain descriptors elicit larger electrodermal responses in chronic pain patients than in controls. Nevertheless, the strong reactivity also concerns other emotional words ; therefore this is not a specific effect. The second part of this work includes two experiments during which the perception of interoceptive sensations arising on the hands was quantified. Non-depressed chronic pain patients reported more numerous, more diversified, more extended and longer lasting sensations than controls. Such a somatosensory amplification appeared reduced if the sensations are considered as induced by an external source. This link in chronic pain between the increase of the vegetative reactivity and the amplification of interoception is discussed

Full textEmotion is identified by a conjugated mobilization of body and spirit. This particular matter of fact explains why anyone dedicating oneself to the study of human being pays a special attention to it. Very early, physicians notice its influence in the genesis of hysteric disorders and, more widely, of mental illnesses. They describe its effects and try to clarify its mechanisms to prevent or treat these disorders. Then, physiologists proceed to a systematic study of nervous physiology. They so bring to light the reactions of sympathic system during every kind of excitements, amongst which they identify the emotional stim1ulations. At last, psychologists in their efforts to understand human behavior, will attempt to study functions of an increasing complexity. Having discovered the laws of sensations and movements, they widen their investigations towards the superior functions, cognitive and emotional. By the end of the XIXth century, the meeting of these three areas of research let appear benefits offered by the use of physiological methods in order to identify the markers of emotional phenomena. However it is only with C.G. Jung’s first psychoanalytical researches that the most effective amongst these markers, that is to say the électrodermal reaction, will be identified and granted

Full textAs an assessment tool for individual’s functional state, autonomic indices can help improving our knowledge of drivers’ behaviour, which is a central road safety causal factor. This work is focused on driver’s mental workload assessment, relying on electrodermal activity analysis. This is an attempt to highlight the most reliable electrodermal indices with the aim to distinguish accurately mental workload elicited by actual driving situations. The analysis of about thirty phasic indices, led to differentiate nominal driving situations. These were selected on the basis of comparable behavioural requirements, but of differences cognitive processes. After appropriate signal processing, (using log transformations in particular), electrodermal responses amplitude has the most potential to distinguish among experimental conditions. However, some of the differences about mental workload were not exactly those which were previously expected. An alternative interpretation of results highlighting anticipation processes is thus proposed. Tonic variations were then studied in a dual task experiment, including two new indices. The distractive power of several secondary tasks, performed while driving, was to be evaluated using these indices. One of the indices was unrelated to signals’ profile. Conversely, the two others gave a clear distinction of potential distraction elicited selectively by each secondary task. Mental workload was thus showed as being evaluated accurately using electrodermal activity analysis. Using objective physiological data and defining new electrodermal indices brought more reliability in the field of mental workload. Thus, electrodermal activity is a good candidate to complete data usually brought by tests or questionnaires

Full textThis thesis was carried out in a multidisciplinary approach that combines experimental protocol, instrumentation, in vivo measurements, physiological change detection instants and identification and preprocessing of measurement artefacts for marathon runners. We considered the analysis of the heart rate variability (HRV) and the electrodermal activity (EDA) recorded during a semi-marathon including pre and post competition periods. A study of the HRV and EDA change detection was carried based on the mean and the trend using the Filtered Derivative with pValue method (FDpV) throughout this thesis. This segmentation method is based on a dynamical approach using a piece-wise stationary model. As a result, itallowed to introduce an index of cardiac regulation for semi-marathon runners. Physiological state changes tracking of affective dimension i.e. "stress" and motivation via the EDA by change detection on its tonic component which reflects the EDA general trend throughout a semi-marathon was also proposed. This enabled us to characterize start and finish phases of a race which are key elements in any competition. A special attention was given to the tonic component of the EDA reflecting the overall level of affective activation. We compared three methods of tonic level extraction by taking into account the present potential artefacts. Thiswork focused on case studies; It can be generalized over a cohort and include more physiological parameters such that VO2 or EEG. Hence, a classification of stress states may also be considered and represent other significant features for characterizing in vivo physiological data for sport performance optimization

Full textThe aim of this thesis work is to identify the existing relationships between different attachment styles and the development of socio-emotional competences such as emotion regulation and empathy in adulthood. According to a multidimensional perspective, emotional regulation, affective empathy, cognitive empathy and prosocial behaviours can be regarded as interacting components with different developmental trajectories and disturbances depending on the individual's relational history. The influence of attachment experiences on the development of empathic capacities can thus be characterized at different levels ranging from cognitive and emotional processes to physiological responses. The aim of the first study was to evaluate the influence of attachment styles on self-reported emotional regulation capacities and difficulties and cognitive and affective dimensions of empathy in adults. Results showed higher scores of personal distress and fantasy in insecure-anxious individuals than in secure and insecure-avoidant individuals. The results also revealed that individuals with anxious attachment reported more emotion regulation difficulties than insecure-avoidant individuals. In addition, PLS-PM modeling analyses showed that the mediating role of emotion regulation in the relationship between attachment and empathy varied according to attachment styles and dimensions of empathy. The aim of the second study was to examine the effects of attachment styles (secure, insecure-anxious, and insecure-avoidant) on physiological activation (i.e. electrodermal activity) during a cognitive empathy task (i.e. self and other perspective-taking) in response to socio-emotional attachment situations (situations of distress, comfort, and neutral interactions ; BAPS ; Szymanska et al., 2015). Regarding distress situations, results showed that insecure-anxious individuals had higher physiological responses than secure individuals when adopting a self-perspective. Regarding comfort situations, insecure-anxious individuals presented higher physiological responses than secure individuals in the other perspective-taking condition. Correlational analyses also revealed an important negative association between perspective-taking scores and physiological responses in secure individuals. Taken together, both studies suggest that the perception of attachment experiences is associated with different socio-emotional competences such as empathy and emotion regulation. These differences are associated with specific physiological responses to socio-emotional attachment situations. Thus, the analysis of attachment experiences is a major line of work, both for the development of scientific research protocols and for therapeutic applications. A range of research perspectives and clinical and therapeutic applications are opening up and will therefore be discussed in light of these conclusions

Full textPerspective-taking (PT) refers to the ability to understand the psychological point of view of others. It is a complex notion involving the ability to become aware of oneself and others, to inhibit one's point of view, to move from one point of view to another and to adopt the perspective of others. These various stages mobilize self-consciousness (CS), self-other distinction (SOD) and cognitive flexibility (CF).Our research aims to evaluate how deficits in each of these spheres could underlie an alteration of perspective-taking abilities. To do so, it uses three original protocols aimed at clarifying the links between PT and the other empathic components by using physiological measures, evaluating the deficits of the processes mentioned in subclinical depression and to test the effect of two training programs (CF, PT) on depressive symptomatology.The results show PT involvement as a transversal process of empathic responses and its connection to the automatic components of empathy. They also support the existence of a pattern of deficits in CS, SOD, FC and PT similar to those found in clinical depression levels. Finally, the effectiveness of PT training on PT capabilities adds an argument to the causal link between these two concepts. Our results contribute to a better understanding of the dynamics driving a chain of interrelated deficits to better prevent the emergence of depression among people at risk

Full textDriving is one of the few activities which require both training and initial examination, but for which there are neither critical situation testing nor regular refresher courses. This creates two key problems: Through a lack of knowledge of the driving aids and safety systems offered by car manufacturers, drivers may fail to use or may misuse them in normal driving situations; secondly, an emergency situation may become critical if the driver has not previously experienced it in controlled conditions. The aim of this study was to check novice and experienced drivers’ ability to use the driving aids and safety systems proposed for vehicle longitudinal control in both nominal and critical situations. Trials were carried out in the field, on tracks and on driving simulators. The uniqueness of the study comes from combining driver behaviour and performance measurements to best correspond to the attention and workload observed when drivers were subjected to these situations. We therefore favoured the use of continuous physiological measures, and in particular electrodermal activity. The results enabled us to conclude that the use of these systems in critical situations was often inappropriate and necessitated a high workload. These conclusions led to the development and deployment of two training programmes in order to compensate for the lack of knowledge and misuse of the driving aids and safety systems
