How and for whom does a positive affect intervention work in fibromyalgia: An analysis of mediators and moderators.
2019
Objectives: Psychological interventions designed to enhance positive affect are promising ways to promote adaptive functioning in people with chronic pain. However, few studies have addressed the efficacy of positive affect interventions in chronic pain populations and examined which patients can benefit more from them. The aim of the present study was to identify mediators and moderators of the best possible self intervention (BPS) in fibromyalgia patients.Methods: We used data from a previous randomized controlled trial that examined changes in pain interference, depression, self‐efficacy and quality of life after the BPS intervention.Results: Mediation analyses showed that depression med…
Attentional biases toward emotional images in the different episodes of bipolar disorder: an eye-tracking study.
2014
Attentional biases toward emotional information may represent vulnerability and maintenance factors in bipolar disorder (BD). The present experimental study examined the processing of emotional information in BD patients using the eye-tracking technology. Bipolar patients in their different states (euthymia, mania, depression) simultaneously viewed four pictures with different emotional valence (happy, neutral, sad, threatening) for 20 s while their eye movements were monitored. A group of healthy individuals served as the control. The data revealed the following: (i) a decrease in attention to happy images in BD patients in their depressive episodes compared to healthy individuals, and (ii…
Anatomical networks reveal the musculoskeletal modularity of the human head
2015
AbstractMosaic evolution is a key mechanism that promotes robustness and evolvability in living beings. For the human head, to have a modular organization would imply that each phenotypic module could grow and function semi-independently. Delimiting the boundaries of head modules and even assessing their existence, is essential to understand human evolution. Here we provide the first study of the human head using anatomical network analysis (AnNA), offering the most complete overview of the modularity of the head to date. Our analysis integrates the many biological dependences that tie hard and soft tissues together, arising as a consequence of development, growth, stresses and loads and mo…
Automatic Assessment of Depression Based on Visual Cues: A Systematic Review
2019
International audience; Automatic depression assessment based on visual cues is a rapidly growing research domain. The present exhaustive review of existing approaches as reported in over sixty publications during the last ten years focuses on image processing and machine learning algorithms. Visual manifestations of depression, various procedures used for data collection, and existing datasets are summarized. The review outlines methods and algorithms for visual feature extraction, dimensionality reduction, decision methods for classification and regression approaches, as well as different fusion strategies. A quantitative meta-analysis of reported results, relying on performance metrics r…
Recognition of emotional states by visual facial analysis and machine learning
2018
In face-to-face settings, an act of communication includes verbal and emotional expressions. From observation, diagnosis and identification of the individual's emotional state, the interlocutor will undertake actions that would influence the quality of the communication. In this regard, we suggest to improve the way that the individuals perceive their exchanges by proposing to enrich the textual computer-mediated communication by emotions felt by the collaborators. To do this, we propose to integrate a real time emotions recognition system in a platform “Moodle”, to extract them from the analysis of facial expressions of the distant learner in collaborative activities. There are three steps…
A multi-componential methodology for exploring emotions in learning
2018
Studies on emotions in learning are often based on interviews conducted after the learning. Therefore, these do not capture the multi-componential nature of emotions and how emotions are related to the process of learning. We see emotions as dimensional and multi-componential responses to a personally meaningful events and situation. In this methodologically frontline study we developed a multi-componential methodology, which provides complementary information about emotions during learning. In this study, by using a within subject design of one person, we focused on emotions during the professional identity learning. In a laboratory setting, the subject was shown personally meaningful vide…
Emotion regulation in patients with somatic symptom and related disorders: A systematic review
2019
BackgroundSomatic symptoms and related disorders (SSD) are prevalent phenomena in the health-care system. Disturbances in emotion regulation (ER) are commonly observed in patients suffering from SSD.ObjectivesThis review aimed to examine ER processes that characterize SSD by a systematic analysis of the available empirical studies.Data sourcesPsycINFO and PubMed databases for the articles published between January 1985 and June 2018.Search terms"emotion/al regulation" or "affect regulation" and various forms of SSD.Study eligibility criteriaEmpirical studies that a) assigned adolescent or adult patients suffering from SSD based on a clinical diagnosis, and b) examined the relationship betwe…
Automatic brain response to facial emotion as a function of implicitly and explicitly measured extraversion.
2010
Extraversion/introversion is a basic dimension of personality that describes individual differences in social behavior and sensory sensitivity. Previous neuroimaging research exclusively relied on self reports for assessing personality traits. In recent years, implicit measures of personality have been developed that aim at assessing the implicit self-concept of personality and complement self report instruments which are thought to measure aspects of the explicit self-concept of personality. In the present study functional magnetic resonance imaging was used to examine automatic brain reactivity to facial expression as a function of both implicitly and explicitly measured extraversion in 3…
Subliminal fear priming potentiates negative facial reactions to food pictures in women with anorexia nervosa.
2010
BackgroundTo investigate hedonic reactivity and the influence of unconscious emotional processes on the low sensitivity to positive reinforcement of food in anorexia nervosa (AN).MethodAN and healthy women were exposed to palatable food pictures just after a subliminal exposure to facial expressions (happy, disgust, fear and neutral faces), either while fasting or after a standardized meal (hungerversussatiety). Both implicit [facial electromyographic (EMG) activity from zygomatic and corrugator muscles, skin conductance, heart rate, and videotaped facial behavior] and explicit (self-reported pleasure and desire) measures of affective processes were recorded.ResultsIn contrast to healthy wo…
Attentional biases to emotional scenes in schizophrenia: An eye-tracking study
2020
Attentional biases to emotional information may play a key role in the onset and course of schizophrenia. The aim of this experiment was to examine the attentional processing of four emotional scenes in competition (happy, neutral, sad, threatening) in 53 patients with schizophrenia and 51 controls. The eye movements were recorded in a 20-seconds free-viewing task. The results were: (i) patients showed increased attention on threatening scenes, compared to controls, in terms of attentional engagement and maintenance; (ii) patients payed less attention to happy scenes than controls, in terms of attentional maintenance; (iii) whereas positive symptoms were associated with a late avoidance of …
