Belin, Laurine. "Impact des stimuli visuels sur la réactivité émotionnelle." Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1B058.
Full textIn this thesis, we wondered if some visual stimuli could have universal emotional valence in vertebrates. A first series of experiments was conducted in the laboratory on various species of birds (e.g. starlings, Japanese quail and raptors). Each species of bird tested, negatively perceived a visual stimulus in particular. Indeed, during its display this stimulus induced 1) rapid withdrawals/takeoffs in a majority of individuals (about 2 seconds after the start of the display); 2) a change of trajectory of a group of birds in flight, and 3) kept a negative emotional valence for birds, even after repeated displays. In a second phase, the same stimulus was tested on a wide range of bird species (eg shorebirds, gulls, ducks and pigeons) under natural conditions. We were then able to 1) validate the negative emotional impact of this stimulus; 2) reveal a different sensitivity to color characteristics of the stimulus according to species, and also 3) its long-term effectiveness on bird food context. Finally, the perception of visual stimuli whose emotional valence was known in birds has been studied in horses and humans. Visual attention was mainly noted in these two species. Moreover, the presence of an autism spectrum disorder seems to influence the perception of certain visual stimuli. This work has highlighted the existence of a visual stimulus with universal emotional valence in birds. The influence of two factors on the perception of the emotional valence was also revealed: 1) specific factor and 2) developmental factor

Full textIntroduction: Sensory, emotional and social cognition represent the processing of internal and external information required by the subject to adapt to the environment. A psycho-trauma is defined as an event that threatens the physical and psychological integrity of an individual, and acts as a sudden and intense intrusion of the cognitive system exposed to danger. This psycho-traumatic intrusion leads to sensory, emotional and social cognitive damage, caused by alterations in the neuromodulation system of the brain structures affected. These cognitive sequelae give rise to the post-traumatic symptoms that constitute post-traumatic stress disorder (PTSD), including perceptual disorders. PTSD is also associated with other comorbid psychiatric disorders, including psychotic disorders. Our work proposes the hypothesis of a "cascade" clinical understanding of psycho-trauma. It supports the idea that sensory, emotional and social cognition articulate with each other and with the environment, and participate in the evolution of the continuum between psycho-trauma and psychotic disorder.Methods: The aim of our research is to study the role of sensory, emotional and social cognition in post-traumatic perceptual disorders. This work is illustrated by two prospective, longitudinal 6-month clinical research studies. PROJECT 1: Identification of markers of emotional and social cognition associated with acoustic-verbal hallucinations (AVH) in the general pediatric population, then in the clinical pediatric population with PTSD. PROJECT 2: Impact of persistent post-Covid-19 olfactory disorders on quality of life, hedonic experience and anxiety and depression dimensions in an adult population.Results: PROJECT 1: The study, carried out in a general pediatric population, included 40 patients (30 girls, 10 boys) with a mean age of 12.8 years. Negative emotions (sadness, fear, anger) were significantly found in the group with persistent AVH at 6 months. Persistent AVH were significantly associated with the diagnosis of PTSD (p=0.01). The study conducted in a clinical pediatric population with PTSD included 31 patients (25 girls, 6 boys) with a mean age of 12.9 years. Negative emotions (patient guilt and maliciousness of HAV) were significantly associated and correlated with persistence of HAV. Negative emotions (disgust, fear and anger, and diagnoses of depression and anxiety) were also associated with PTSD persistence at 6 months. The persistence of HAV was significantly associated with the emergence of a diagnosis of psychotic disorder at 6 months (p=0.01). PROJECT 2: The study included 56 patients with a mean age of 39 (33 women, 23 men). Olfactory disorders were significantly associated and correlated with negative emotions (quality of life, loss of pleasure). Patients with sensory distortion (parosmia, phantosmia) were more significantly impacted emotionally than patients with no sensory perception (anosmia). Although they "objectively" recovered their sense of smell on the psychophysical test, patients who "subjectively" perceived the persistence of an olfactory disorder responded to PTSD symptoms and were more emotionally impacted (quality of life, loss of pleasure, anxiety and depression).Conclusion: Sensory and emotional cognitions are significantly linked after a traumatic event. Their articulation contributes to the onset and maintenance of perceptual disorders. They are also involved in the development of post-traumatic clinical symptoms, PTSD and other associated psychiatric disorders, including psychotic disorders. The evolution of post-traumatic symptoms requires a dimensional reading for a better clinical understanding, preventive monitoring of risk factors for poor psychiatric evolution, and a therapeutic proposal targeting sensory and emotional cognition

Full textThe eating disorders (ED) represent today a major problem of public health in the majority of the Western countries. The researchers highlighted the need for better understanding the influence of the emotional regulation on the food behavioral problems. We tried to study a broad register of emotional processes and their bonds with various psychopathological and neuropsychological dimensions. This in order to better define the various components which underlie the ED, to better understand the nature of their specific profiles, thus to allow to better categorize them. Thus to pose the bases of a finer categorization of the disorders should make it possible to improve the specificity of the responsibility of therapeutic assumptions and the forecast. Our population is composed of 23 anorexics, 26 bulimics compared with 41 subject controls. We studied the dysregulation emotional in patients ED through the study of emotional features (alexithymia, anxiety, impulsivity, anger, emotional lability), and various cognitive measurements (attention, working memory, inhibition, cognitive flexibility, decision-making). With a search of their relationship to other dimensions (food, cognitive and emotional) enabled us to better specify this disorder. In particular our results highlight a nonspecific dysregulation emotional in patients ED

Full textEmpathy and emotion regulation are vital processes for healthy socioemotional functioning. Empathy refers to the ability to share and understand others’ emotions while emotion regulation is defined as by the ability to modulate one owns’ emotional state. It is commonly described, from a theoretical perspective, that empathy and emotion regulation are intimately related. However, empathy and emotion regulation have been largely studied separately. In addition, the vast majority of the neuroscience literature on empathy is based on functional neuroimaging studies of vicarious pain. Empathy is although a versatile social function deployed in a large range of socio-emotional interactions. Like emotion regulation, emotional valence is rarely examined in the context of empathy and the relation between emotion regulation and emotional valence during empathy is currently unexplored. The objective of this thesis was to examine the relation between empathy, emotion regulation, and emotional valence, as well as their underlying neurophysiological correlates. In a narrative review article, the key brain regions involved in pain empathy are described, which includes the median anterior cingulate cortex and the anterior insula. In addition, factors that regulate the brain response during pain empathy were pointed out. These included different visual stimuli that regulate differently perceptual processes, such as body parts being submitted to noxious pain or facial expressions of pain. Instructions offered to the participants is also a factor that cognitively regulate the brain response during pain empathy, such as instructions oriented towards oneself or the other. In a second article, a quantitative meta-analysis on functional neuroimaging studies of pain empathy is presented. This study revealed a core network of activation related to pain empathy (median anterior cingulate cortex, anterior insula), which activates independently from perceptual and cognitive processes of regulation. This study also demonstrated that different perceptual processes distinctively activate sensorimotor regions (observation of limbs in painful situations) and a region involved in action imitation and non-verbal communication (facial expressions of pain). Furthermore, different cognitive regulatory processes distinctively activate a region involved in interoception and selfawareness (self-oriented perspective) and regions involved in the attentional network (perspective oriented towards the stimulus). In order to examine experimentally the effect of emotion regulation on empathy, a psycho-physiological study was then conducted. A new paradigm was developed. During the viewing of short videos depicting socioemotional interactions, participants were invited to regulate their emotions using cognitive reappraisal. Situational empathy was measured. Electrodermal and cardiac activity was gathered. Results showed that emotion regulation can increase or decrease situational empathy and is associated to an increase of the heart rate variability. These results suggest that emotion regulation is underpinned by the parasympathetic system during empathy. Moreover, viewing positive emotions, compared to negative emotions, was associated with less situational empathy and a slight increase of the heart rate variability. These results suggest a greater need in emotion regulation processes during empathy for positive emotions. In sum, this study demonstrates that emotion regulation process during empathy is preferentially underlied by the parasympathetic system. This work also highlights that emotional valence is an important parameter to consider when studying empathy, as it influences the underying subjective and autonomic responses. In addition to offer a more integrative vision of the relation between empathy and emotion regulation and supports their link empirically. The findings demonstrate that empathy is a dynamic phenomenon that can be regulated by v perceptual and cognitive processes. Ultimately, this thesis will contribute more nuanced models of empathy that will consider emotion regulation processes and the underlying neurophysiological basis.

Full textThe spontaneous manifestations of emotion are studied during a problem solving. The relations between variations of skin conductance and facial expressions with the solving events of failure and success are studied. We examine the modulation of these manifestations according to the social dimension of the situation and the stressing nature of the task. Our results highlight specific physiological and expressive variations in impasse situations and sub-goals reaching. They underline the relationship between the difficulties encountered in the solving and the spontaneous manifestations of the emotion. The results relating to the modulating elements of the emotional manifestations show the effect of social dimension on the physiological components of the emotion and the effect of the stressing nature of the task on the expressive components. These spontaneous manifestations of the emotion during the problem solving are interpreted within the general framework of the appraisal theories, in the light of the data relating to works on the nonverbal communication and the relationship between emotion and problem solving

Full textThis research deals with the links between emotional experience, emotional information and information processing. The emotional experience which is particular to each individual defines his own information processing (Schwartz & Clore 1983). Yet emotions emerge through a process of situation valuation and his current connection to it. Following these emotional experiences, the individual starts to develop knowledge about emotions related to their different characteristics (Harris 1983). This knowledge subsequently determines the reader's emotional experience (Fridja 1989). The main objective of this research is to study to what extent the emotional content of a story influences the construction of its meaning and what the factors likely to mediatise this influence are. 256 children have read three stories from children's literature where emotional degree changed (positive vs. Negative vs. Ambiguous). At the end of each reading, they had to answer questions about the story and write a text telling the story they had read. The results show that the children have difficulties understanding the positive story. They do understand it less accurately Emotional induction is moderate. Finally, the most favourable factors for creating meaning from a story are the characteristics of the situation. When children rely on the characteristics of the situation when working with each other ot preparing their written production, their understanding is much better

Full textThe filmic document, widely used by teachers of French as a Foreign Language (FFL) since 1970, is an extremely powerful inducer for emotions and a way to show their expression. Since cognition, emotion and culture are closely related, it is relevant to understand the interest of the use of emotionally charged film clips to teach FFL learners.In order to see if it is advantageous to use an emotional movie extract in the teaching process, a corpus of clips taken from New Wave films was formed. The emotional induction with these extracts and the focus of attention induced by negative emotions inducing extracts are tested in 60 B2 level foreign participants. An experiment was conducted to observe the extent to which it is suitable to use an emotion inducing film clip. 51 Chinese participants were involved. It was noted that 28 of them have difficulty in being empathic while experiencing intercultural communication with a native speaker. The effect of thedramatization of an extract on the ability to empathise is apprehended.This research shows the importance of an educational use of emotion. Extracts inducing negative emotions focus learners' attention. Participants that dramatize this type of extract optimally memorize gestures of the characters. Discussing the emotions induced by an extract leads learners to develop their sense of social proximity with the teacher. The research also indicates that learners, after viewing a dialogue in an extract comprising terms of emotional lexicon, remember better emotionally loaded verbal material. Finally, the results show that emotion can be taught, when learners are having difficulties be empathic towards natives. It is also determinated that the dramatization of a film clip can develop their empathy ability

Full textEn premier lieu, nous avons voulu explorer la capacité de la VP à traiter des images de scènes naturelles dont certaines contiennent des informations émotionnelles. Nous avons notamment observé pour la première fois l'existence de composantes électrophysiologiques évoquées par la VP. De plus, nous avons pu constater que le contenu émotionnel des images module les performances comportementales des participants ainsi que leur activité cérébrale, comme classiquement décrit en VC. Ces résultats plaident en faveur d'une différentiation précoce des informations visuelles présentées en VP selon leur nature affective et permet d'envisager leur utilisation dans le cadre de la rééducation neurovisuelle.
En deuxième lieu, et ayant à l'esprit les possibilités de rééducation neurovisuelle, nous avons cherché les stimulations susceptibles de mobiliser au mieux les ressources visuelles, pour ensuite les associer, en VP, à des informations émotionnelles. En conséquence, nous nous sommes intéressés au traitement de visages émotionnels (peur, neutre, joie) en VP car ils constituent, du fait de leur rôle dans les interactions sociales, des stimulations visuelles particulièrement saillantes. Cette étude a permis de montrer que les visages sont traités en VP et que leur expression émotionnelle a un impact au niveau comportemental et électrophysiologique. En particulier, les réponses des participants sont plus rapides et les composantes évoquées sont plus amples lorsque des visages de peur et de joie sont présentés en VP par rapport à des visages neutres.
Enfin, certaines études suggèrent une amélioration des performances de la VP lorsque des stimuli sont présentés en mouvement. De ce fait, la saillance des visages en VP pourrait être renforcée par le caractère dynamique de leur expression émotionnelle. Dans une troisième expérience, nous avons donc présenté des visages statiques et des visages animés, neutres et émotionnels, en VC et en VP. Les résultats obtenus confirment les données de la seconde expérience mais ne permettent pas d'attribuer un avantage spécifique à la composante dynamique des visages présentés, qu'ils soient émotionnels ou neutres.
A titre prospectif, nous avons présenté, à des patients atteints de scotomes centraux, des visages émotionnels et neutres. Les résultats comportementaux permettent de mettre en évidence que, chez ces patients, les visages émotionnels sont mieux traités que les neutres en VP. Les expressions faciales émotionnelles pourraient donc s'avérer des stimuli particulièrement adaptés dans le cadre de l'amélioration des ressources de la VP.
En conclusion, ce travail apporte des données comportementales et électrophysiologiques inédites sur le codage de l'information émotionnelle en VP et ouvre des perspectives encourageantes sur l'utilisation de la saillance émotionnelle dans la rééducation des déficits de la vision centrale.

Full textAlzheimer’s Disease (AD) is a complex neurodegenerative pathology involving large brain alterations and the emergence of cognitive and behavioral symptoms that impair daily life. The systematic assessment of brain alterations that occur during the first stages of AD showed the existence of amygdala atrophy, which could lead to disruptions in emotional processing. The objective of this thesis is to further investigate these disruptions. In this perspective, we conducted paradigms involving emotional attention, in other words, attentional processes directed toward emotional or neutral stimuli. In healthy individuals, these processes are engaged more efficiently toward emotional stimuli. This mechanism may be disrupted in patients with amygdala lesions. We conducted two eye-tracking paradigms (i.e., eye movements recording) involving visual search and pro-saccade/anti-saccade tasks to get a precise analysis of attentional processes. The results of these two studies suggest that patients with AD present alterations of early emotional attention, which is involved in facilitating orienting toward emotional information. Using a neuroimaginganalysis of structural and functional connectivity, we highlighted alterations in neural networks (including the amygdala) involved in attentional and emotional processes. Finally, we present the preliminary results of a neuroimaging study specifically exploring correlations between emotionalattention processes and alterations in the corresponding neural network. Our data highlight (a) the presence of distinctive emotional attention deficits in patients with AD, and (b) alterations in a large neural network including notably the amygdala, which may explain our behavioral data

Full textEmotion and scientific discourse are, by tradition, considered to be incompatible due to the subjective nature of the former and the objectivity requirements of the latter. The thesis deals with a study of the processes involved in emotion generation in relation with discourse generation. This is followed by the approach of the modes or strategies of inclusion of emotion manifestation phenomena in the final discourse. The study combines a psychological and linguistic approach of emotions, and revolves around the transition stage between the mental domain and that of language elaboration, leading to communicating the previously generated emotions in discourse (link between cognitive appraisal and the Appraisal theory in linguistics). The thesis sums up the broad categories of inclusion modes, as well as the main global emotion/affect load manifestation types. This very synthesis is the result of the research and analysis of emotion manifestations deliberately or accidentally included into a selection of articles sampled out from english-speaking peer-reviewed scientific press. One of the goals was to determine if scientific discourse contains and displays the authors' subjectivity and emotion manifestations, and how these phenomena are encoded in texts that are primarily meant (according to norms and conventions) to be as objective and neutral as possible, regardless of the subject. Thus was raised the question of the importance of the share taken by emotion in any discourse, from its generation to the moment it is uttered

Full textAdvances in oncology have considerably improved the overall survival of cancer patients, thus understanding their toxicities and cerebral impacts is a major issue to maintain patients' quality of life (QoL). Certain cancer treatments can indeed lead to cognitive dysfunctions referred to as "cancer related cognitive impairment" (CRCI), which can impair Qol and compromise the autonomy of elderly patients. In this thesis work, we leverage preclinical models to decipher the direct impact of new-generation hormone therapies used in prostate cancer and of immunotherapies in the immune and inflammatory context linked to cancers, in the occurrence of cognitive, and/or emotional deficits as well as "fatigue". In a first study, we demonstrated the impact of the hormone therapies Enzalutamide and Abiraterone Acetate/Prednisone on exploration activity and spatial learning, in relation to brain altered dopaminergic transmission. In a second work, we showed that systemic inflammation, blood-brain barriers permeability accompanying meningeal infiltration of peripheral macrophages and neuroinflammation as well as deficits in cognition or emotional reactivity, depending on immuno-inflammatory or immune-desert cancer type. Combined with cancers, anti-PD-1 or -PD-L1 treatments exacerbate the decline in executive functions, while PD-L1 specifically relays the infiltration of a lymphocyte subpopulation in meninges implicated in cognitive deficits and anxiety. This work proposes new systemic biomarkers and original ways of intervention to improve the cancer patients QoL treated with new-generation therapies

Full textSocial cognition is defined as our ability to interpret others' behaviour in terms of mental states (thoughts, intentions, desires, and beliefs), to empathize with others' state of mind and to predict how others will think and act. This kind of capability is used, for example, to « read » and to understand the emotional expressions of other people. Within the framework of this research we are interested in children's abilities to express and to interpret the emotional manifestations of other people as a highly mediating factor for their successful social adjustment. This question was explored from both a developmental and comparative perspective. We studied the developmental trajectories of 90 typically developing children, divided into three age groups of 4, 6 and 8 years, and compared them with those of 12 high-functioning autistic children. These groups were assessed with a number of tasks: an affective judgment task from pictures and stories, a narration task using scenes of emotional content and an interview about emotions (composed by production and evocation tasks). Results of the developmental study show that, as typical children get older, they increasingly provide adequate target responses, confusion between emotions decreases and finally they produce more complex narratives and develop expressive capabilities. Furthermore, results of the comparative study show that the autistic population is also able to recognize emotional information from faces, but they show significantly worse performance on other emotional tasks than typical children do. These results are discussed in relation to former research in the domain of emotional, pragmatic and theory of mind

Full textThe objective of this research is to analyze more precisely the juncture between emotion and cognition from an experimental approach based on one hand on the use of a complex and standardized visual material to arouse emotions, and on the other hand a control of the conditions in which those emotions are produced. The research has been carried out in a longitudinal way on the same groupe of subjects submitted to three successive experimental phases, each one separated by a six month interval). The identification and emotional acknowledgment test have shown an excellent long term memorisation of the experimental material (whether visual or verbal) whenever this is emotionally significant to the subject. In other respects, the cognitive constraint imposed on the subject () influences his emotional experience and modifies his speech with regard to the other conditions. It also allows a better discrimination of emotions from texts the subject has not produced. Finally, the subjects were also able to identify the stimuli which provoked the initial emotional experience in other individuals, and this identification was even better when the cognitive constraints were stronger. To conclude this analysis, a new model of judgement of emotions is proposed and considered from both an irrational (immediate apprehension) and rational (categorical assessment) point of view. Such a model could, from a methodological point of view, provides a new perspective of the cognitive assessment (of emotions)

Full textStabilized schizophrenia is characterized by cognitive and emotional deficits. Recent works adopted a dynamic view of the relationship between cognition; motivation and emotion in schizophrenia. The objective of this work was to describe the impairments of recognition; subjective feelings and physiological reactions related to emotions in stabilized schizophrenia. The influence of cognitive impairment and apathy on the emotional processes was also explored. In a first study on a group of 23 patients with schizophrenia; we highlighted the introduction of bias in the recognition of emotion in two sensory modalities (visual and auditory). In the next study; we investigated the influence of executive function disorders in the subjective feeling of emotions. With film excerpts; we showed that a disorder in executive functions could lead the introduction of a mixed subjective feeling in schizophrenia. Apathy is a common disorder in schizophrenia and may influence emotional processes. In a third study; we investigated the impact of apathy on physiological reactions induced by emotion. We have shown that the severity of apathy was correlated with a decrease in electrodermal activity during induction of positive emotions. The results of these studies show an impact of cognitive and motivational disturbances in emotional processes in stabilized schizophrenia. This work encourages us to explore the neural bases of the interaction between emotion and cognition in schizophrenia. Clinical applications are also discussed

Full textAccording to Suls (1972), humor relies on the perception of a situation from two self-consistent but normally incompatible frames of reference, leading to incongruity. The subsequent resolution of the incongruity triggers positive emotional states such as mirth. Yet, the emotional experiences triggered by humorous situations are mostly disregarded in Suls' model. The aim of the present dissertation is to highlight that the relation between cognitive and emotional elements is crucial in the examination of the humor process. Indeed, a growing focus on the interrelation between cognition and emotion can be found in the literature. Because black humor relies on social norm transgression, it allows us to examine both the cognitive assessment and the variability of emotional responses triggered by this humor style, compared to nonblack humor. Finally, we propose a cognitive-emotional model to promote the study of the relationships between the cognitive and emotional aspects of humor
Bourgais, Mathieu. "Vers des agents cognitifs, affectifs et sociaux dans la simulation." Thesis, Normandie, 2018. http://www.theses.fr/2018NORMIR20/document.
Full textOver the last few years, the use of agent-based simulations to study social systems has spread to many domains (e.g. geography, ecology, sociology, economy). These simulations aim to reproduce real life situations involving human beings and thus need to integrate complex agents to match the behavior of the people simulated. Therefore, notions such as cognition, emotions, personality, social relations or norms have to be taken into account, but currently there is no agent architecture that could incorporate all these features and be used by the majority of modelers, including those with low levels of skills in programming. In this thesis, the BEN (Behavior with Emotions and Norms) architecture is introduced to tackle this issue. It is a modular architecture based on the BDI model of cognition featuring modules for adding emotions, emotional contagion, personality, social relations and norms to agent behavior. These behavioral dimensions are formalised in a way so they may operate together to produce a believable behavior in the context of social simulations. The architecture is implemented into the GAMA simulation platform in order to make it usable by the social simulation community. Finally, BEN is used to study two cases of evacuation of a nightclub on fire, showing it is currently usable throught its implementation into GAMA and it enables modelers to reproduce real life situations involving human actors
Arnaud, Sarah. "La conscience émotionnelle. Sa fonction dans l’autisme." Thesis, Sorbonne université, 2018. http://www.theses.fr/2018SORUL125.
Full textMy thesis is about emotional consciousness and its function in autism. The main hypothesis is about the particularities of autistic people’s own emotions: autistic people would mainly have a “cognitive access’ to the consciousness of their emotions while neurotypical people’s emotional consciousness would appear thanks to phenomenal data. A secondary hypothesis is about the relationship between these particularities and the particularities of emotional lives of autistic people: the particularity of emotional consciousness would foster anxiety, alexithymia, and emotional dysregulation, which are observed in autism. It would also be the source of particularities of emotion recognition in autism. The first chapter presents the results of studies in psychology about emotion particularities in autism. Chapter 2 and 3 give operational definitions of “consciousness” and “emotions”. The last chapter proposes an interpretation of the results of chapter 1, in the light of the terminological distinctions given in chapter 2 and 3. This interpretation is the main hypothesis just mentioned: neurotypical people’s emotions access consciousness above all and most of the time thanks to a phenomenal access, that is to say that the subjective components of emotions access consciousness. In autism, it is rather a cognitive access mode that allows their emotions to access consciousness: objective and descriptive components access consciousness

Full textIn this thesis, the objective is to understand the relationships between academic success (academic performance) and subjective perceived stress on the one hand, and the influence of individual differences (emotional intelligence, personality traits and chrono-type) on academic success on the other hand, as well as the interactions between these individual differences and subjective perceived stress. 1) Preliminary study is conducted to clarify the relationship between emotional intelligence and coping strategy among Chinese students expatriated in France; 2) our first study aims to understand the different elements related to the expatriation of Chinese students in France: the causes and criteria of subjective expatriation success, the different sources of stress they encountered as well as their strategies to cope during their expatriation are interviewed; 3) With the elements emerging from our first study, we were able to construct a questionnaire on subjective expatriation success for Chinese students in France. The initial idea is to validate this questionnaire by comparing individual differences (emotional intelligence, cultural intelligence, and chrono-type) with other parameters. Unfortunately, the completion of all these questionnaires took a long time, which explains why few participants completed them, which does not allow us to validate this questionnaire of expatriation success. 4) Finally, we try to understand the relationship between academic success and individual differences among the general population, i.e. French students

Full textVirtual humans are more and more common in virtual environments such as simulations, training softwares, serious-games or video games. Affective computing aims at giving those artificial characters emotional capabilities. We aim at generating virtual humans whose behavior is coherent, adaptative and explainable. We define coherence as the adequacy between the situation, the virtual human’s mental state and her behavior. Adaptability is the capacity to adapt to new knowledge an reason about it. This knowledge may be specified by people without computer programming skills and therefore be incomplete. Finally, the virtual human’s behavior must be explainable in order for the learner to understand the impact of her actions. Using models from psychology that explicitly address the components and their dynamics, our virtual human model is given a personality, an emotional state and is linked to others via social relationships. In order to ensure the adaptability of our virtual human, she is given a set of domain-independent processes to take care of the dynamics of those human components and their impact on behavior. Those processes are integrated on a cognitive architecture. Domain-dependent knowledge such as entities, actions and activities are designed using a description language inspired by ergonomy methodology. This formalism is simple enough to be used without any computer programming skill, and expressive enough to be directly used by the high-level processes of our virtual human. An affective empathy model based on individual characteristics is proposed to model affective relations between virtual humans. To generate such virtual humans, we propose REPLICANTS, a decisional artificial intelligence engine. Some examples are presented and show how the virtual human can combine her generic set of cognitive rules with domain specific knowledge in order to adapt to her environment as well as behaving rationally in pursuing goals

Full textDecision-making under ambiguity is critical in our everyday life. Indeed, we make most of our choices with no information on the potential consequences of these choices or on the probabilities that govern these consequences. To better characterize the underlying mechanisms engaged in this complex ability, we tested the Somatic Marker Hypothesis (SMH), a key theory in this field. This theory posits that decision-making under ambiguity relies on the development of emotional responses to the world (i.e., an integral emotional signal) that bias people toward advantageous choices in ambiguous circumstances. Thus, the goal of this thesis was to test (i) the role of emotional processes and (ii) the possible implication of cognitive processes in our ability to choose advantageously in ambiguous context. In our first study, we investigated the factors at the root of the decision-making deficit of pathological gamblers by assessing the impact of alexithymia – a recurrent emotional disorder in this population – on their decision-making skills. In line with the SMH, we found that alexithymia was a key factor to understand pathological gamblers’ decision-making deficit. In a second study, we designed an emotional priming paradigm to provide direct evidence that decision making relies on the creation of an integral emotional signal in healthy adults. Our data supports the SMH by evidencing that decision-making can be improved when the integral emotional signal is reinforced. Finally, in our third study, we investigated the development of decision-making abilities by focusing on the strategic adjustments in children, adolescents and adults. Our data suggest that the inhibition of a spontaneous tendency to shift after a loss might be critical to choose advantageously. In conclusion, the results of this thesis broadened the scope of the HMS by emphasizing the need to study both emotional and cognitive processes to better understand decision making under ambiguity.

Full textThis thesis presents a linguistic analysis of a selection of poems by John Keats: specifically, the expression and verbalization of emotion by way of language the twenty-six poems that compose the poetic corpus upon which this research is founded. The linguistic approach taken is a cognitive approach, based on the theories of cognitive linguistics, cognitive grammar, and cognitive poetics. Conceptual Metaphor and Metonymy Theory also play an important role in the poetic and grammatical analyses. The approach concerning emotion is an embodied one, based in language, philosophy, and with support from neurobiological research. The goal of this thesis is to examine the ways in which emotion is expressed within Keatsian poetry by a close interrogation of the language itself, thus holding the view that the lexical and grammatical elements—and their semantics—that compose the verses and poems themselves are essential to the salience of the poetic rendering of emotional experience

Full textThe use of hypnotic suggestion is of considerable interest for the study of cognitive processes and their modulations. Over the last few decades, a growing number of studies have demonstrated that direct verbal suggestions, induced in highly suggestible individuals, can lead to drastic, transient and authentic changes in conscious experience and cognition. While these influences have been established for various processes, the impact of hypnotic suggestion has yet to be determined for cognitive processes linked to emotional processing. The aim of this thesis was to characterise the influence of hypnotic suggestion on emotional processes, by studying the modulation of attentional bias and lexico-emotional activation and inhibition processes. More specifically, our work aimed to determine (1) to what extent hypnotic suggestion can intervene in opposing ways on emotional processes, (2) which hypnotic component underlies these modulations, (3) how the effects of emotional dimensions are affected by hypnotic suggestion (4) how hypnotic suggestion can facilitate the inhibition of prepotent responses when processing emotional stimuli. To this end, we combined hypnotic suggestions aimed at increasing or decreasing emotional reactivity with cognitive tasks using emotional words. We carried out four experimental studies using suggestions, combined with emotional Stroop (Studies 1 and 3), lexical decision (Study 4) and sentence completion (Study 6) tasks, accompanied by the validation of a suggestibility scale (Study 2) used to recruit participants, and a corpus of sentences (Study 5) used to construct experimental materials (Study 6). The data highlighted that hypnotic suggestion (Studies 1 and 3), as well as hypnotic induction by relaxation (Study 3), lead to effective modulations of attentional bias in the emotional Stroop task. Furthermore, we have shown that hypnotic suggestion can specifically influence the effect of the arousal dimension of emotional words presented in the lexical decision task (Study 4), and facilitate the inhibition of emotional words in the emotional Hayling task (Study 6). Overall, the results help to clarify the influence of hypnotic suggestion on emotional processes in cognitive tasks using emotional words. They suggest that the modulation mode of hypnosis is plural, being able to influence emotional processes in opposite ways, act on the effect of specific emotional dimensions, and involve several components of the hypnotic procedure. We propose avenues for further research that could lead to a new understanding of the interaction between hypnosis and emotions, and to prospects for clinical application in the field of emotional regulation

Full textPrisons are responsible not only for punishing offenders sentenced to deprivation of liberty, but also for ensuring their safety and respect for fundamental rights, while promoting their social reintegration and combating recidivism. Prisons are also responsible for the medical and psychological care of prisoners who require specialized assistance. This is a mission that the institution is currently having difficulty fulfilling. A number of national and international studies have shown that the mental health of prisoners is much worse than that of the general population. However, few studies have focused on the cognitive and emotional specificities of prisoners. The scientific literature in health psychology and cognitive psychopathology shows the essential role played by these cognitive and emotional processes in the emergence and maintenance of psychopathological states. This doctoral project had two main objectives: 1) To assess how prisoners perceive their health status and how they rate certain dimensions of psychological well-being, according to their age and recidivism status. An initial study was carried out with young and elderly adult prisoners, who completed scales of perceived health (NHP, Mental Health Analog Scale), self-esteem (Rosenberg scale) and body investment (BIS). 2) To assess the role of transdiagnostic cognitive-emotional processes involved in the emergence and maintenance of psychopathological states in detention. A second study examined the links between dimensions of the impulsivity construct and the production of cognitive distortions. Participants, young adults in detention and a comparison group from the general population, completed an impulsivity scale (UPPS) and a cognitive distortions assessment scale (EDC-A).A third study examined the type and nature of cognitive emotion regulation strategies in relation to anxiety and depressive symptomatology. Participants, young adults in prison and a comparison group from the general population, completed questionnaires and scales on cognitive emotion regulation (CERQ) and anxiety and depressive symptomatology (HADS).The results show that prisoners of all ages perceive their state of health to be worse than that of individuals of the same age from the general population. In addition, there are age-related specificities. Indeed, health problems perceived by young inmates are mainly associated with body-related concerns, whereas they are more closely linked to psychological and mental concerns among older inmates. Furthermore, individuals in a situation of recidivism are characterized by a greater perception of emotional difficulties and better perceived mental health. Secondly, the results indicate that inmates display significantly more cognitive distortions, particularly negative ones. Impulsivity was also found to be positively correlated with positive and negative distortions. Nevertheless, a significant moderating effect of the length of detention on these relationships highlights their attenuation with time spent in prison. At the same time, in order to regulate their negative emotions, it appears that prisoners make greater use of dramatization and positive centration than individuals from the general population. Finally, the results highlight specific and distinct cognitive regulation profiles according to the type and intensity of anxiety and depressive symptomatology, in the prison population and in the general population

Full textThis thesis aimed to provide a better understanding of cognitive and emotional processes underlying the decision under risk. Adopting an integrative perspective that includes approaches of developmental psychology, cognitive psychology and psychopathology, we have successively examined (i) cognitive and emotional processes underlying one of the major decisional bias, the framing effect, (ii) the relationship between risk-taking, framing susceptibility and emotion regulation during development, (iii) the role of risk-aversion in rationality of individuals with Autism Spectrum Disorders (ASD) in experimental situations. Our first study, analyzing decisions of adults with typical development, has experimentally confirmed that emotional processes of attraction to sure gains and aversion to sure losses hypothesized by Daniel Kahneman are at the core of framing susceptibility. Moreover, the contrast of several conditions has confirmed the robustness of these emotional processes and allowed to identify that one methodological factor varying between the two main framing tasks moderates framing susceptibility. Our second study, analyzing decisions of children, adolescents and adults with typical development, has explored the relationship between the development of an emotion regulation strategy (cognitive reappraisal) and the development of risk-taking and framing susceptibility. Our results showed that adolescents took more risks than children or adults but this increase in risk-taking was limited to situations with a high level of risk. We found no group differences on the frequency and the efficacy of using cognitive reappraisal and on framing susceptibility. Our third study assessed decision-making of adults with ASD. In order to explore the role of risk-aversion in rationality in individuals with ASD, we have adapted a framing paradigm to create situations in which risk-aversion was alternatively more rational, less rational, or neither more nor less rational than risk-taking. Results showed that participants with ASD took fewer risks than control participants when risk-aversion was more, or as advantageous as risk-taking. In contrast, when risk-aversion was less advantageous than risk-taking, both groups adopted a similar decision pattern. In conclusion, these studies expand knowledge on cognitive and emotional processes underlying the decision under risk and framing susceptibility during typical development and in individuals with ASD

With the aim of studying the efficiency of the schemas therapy, in particular, early maladaptive schemas, we showed that a resistant anxio-depressive patients, the anxious and depressive components are related to the activation of some of the early maladaptive schemas described by Young (1995). The use of its schemas-focused therapy decreases strongly and significantly the levels of anxiety and depression. So, the evolution of the anxio-depressive disorder seems related to the anxious components (4 schemas), and the others in the depressive component (7 schemas), and the others else in both at the same moment (3 schemas) ; and schemas are related neither to the one, nor to the order one (5 schemas)

Full textCognitive impairment includes a heterogeneous set of disorders found in patients with schizophrenia. Among them, patients exhibit clear disadvantages in filtering relevant information in a flow of distractors or the attention of these patients can be captured by the sudden irruption of visual information, even if irrelevant to understand the scene. The objective of our research is to specify these cognitive disorders by approaching the ecological conditions of visual exploration.The study of eye fixations allows to highlight visual exploration strategies or to assess the impact of the stimuli salience on the visual exploration. The salience is defined as the emergence of a form on a background. We can observed a cognitive salience (the object’s relevance), a physical salience (the physical characteristics) or emotional salience. The paradigm of change blindness is defined by the failure to notice changes in scene when these changes occur following brief disruptions, such as eye movements. This paradigm exhibits the advantage to approach natural conditions of exploration using 3D stimuli. Several studies have evaluated different factors having an impact on the detection of changed object with this paradigm. Therefore, the interest of the main object to the comprehension of the scene, the incongruous objects, color, shape or size of the object are characteristics promoting the detection of change.Our initial task consists of the conduct of two distinct studies with healthy subjects testing the influence of two factors on the detection of change: the magnitude of change and the emotional aspect of changed objects. Our first study showed that the more the scene contains changes, the faster, the more efficient we detect at least one change. Our second study showed that the emotional aspect of changed objects impacted their detection. Indeed emotional objects are best detected that neutral objects.Our second study has focused on the visual exploration of patients with schizophrenia compared to healthy subjects during the presentation of scenes of everyday life. We used a paradigm of change blindness including irrelevant changes in the understanding of the scene. This paradigm allows to test the cognitive salience. The main recorded variables were the motor response time and eye tracking data (the latency of the first fixation in a region of interest). Our results exhibited a striking dissociation between the explicit and implicit responses: the patients\\\\\\\' eyes shifted faster toward the changes despite explicitly reporting the change more slowly than the healthy subjects.Finally in our third study, we compared the effect of the sudden irruption of an emotional visual information with the sudden irruption of a neutral visual information using an ecological task of change blindness. We compared patients with schizophrenia to healthy subjects. Results show that changes in emotional objects are better detected than changes in neutral objects only for the healthy subjects.We confirmed the patients\\\\\\\' sensitivity to the sudden onset of visual information with a paradigm that measured a better performance in the patients, which thereby reduced the effects of a non-specific attentional deficit. Moreover, the better detection performances disappear when changes lay an emotional influence, highlighting the difficulties of emotional processing in schizophrenia. Finally, the surprising dissociation between implicit and explicit responses in schizophrenia can be interpreted as a deficit of access to conscious perception, which could be of interest to various therapeutic techniques

Full textWe are studying in exploratory manner the emotional influence of the perceived elementary motions on cognitive process. Simple, elementary movements are represented by a black disk-shape trajectory which are evaluated first in a pre-test according to their emotional valence. The three movements which are considered the more representative of the positive, negative and neutral emotional valences was selected to create our material by four experimental studies. The first two were created to evaluate the cognitive charges provoked by their movements. On the one hand, the memorization by using a word recall tasks with positive, negative and neutral words, on 180 subjects. On the other hand, with a writing speed atsk (57 subjects). The third study deals with the presence or absence of subjective emotional state resulting from the presentation of their movements on 76 subjects. The last study considers the emotional perception of their elementary movements in a population of 90 school aged children. The results obtained show that the perception of elementary movement seems to trigger an emotional process which affects cognitive process, in the two first studies, and does not induct a special subjective emotional state. The results obtained with children allow us to conclude that the perceptive influence of their movements, in emotional states, is observed as soon as twelve years of age and also induces the changing of certain cognitive processes

The objective of this study was to evaluate the process of emotional processing in major depressive disorder byfocusing on cognitive inhibition and the implicit treatment of emotional information. In a first experiment, we evaluated the ability of cognitive inhibition in a population of twenty patients suffering from major depressive disorder, based on the model of Hasher and Zacks (1988), using neutral material. A cross-modal emotional priming task (face, sound, word) was used to assess the implicit process. We used this task on 275 healthy subjects in order to evaluate a possible gender effect and with depressed patients. The main results confirm impairment in cognitive inhibition in patients suffering from major depressive disorder, particularly in terms of access and restraint functions. The emotional priming tesk allows us to confirm the bias toward negative information, correlated with lack of cognitive inhibition. The gender difference, with a greater sensibility for healthy women to negative environment was also found in depressed women. We discuss the consequence of impairment in cognitive inhibition on the processes of emotional regulation in major depressive disorder, and also the issue of female vulnerability, psychopathological and therapeutic.
