Percepções de envelhecimento e estado de saúde na relação com o bem-estar psicológico em adultos activos

Este estudo teve como finalidade investigar a relação que as perceções de envelhecimento, o estado de saúde e os sintomas psicopatológicos têm no bem-estar psicológico, tendo em conta a influência de variáveis (moderadoras ou mediadoras) como o apoio social percebido e o estado emocional. Foram equacionadas quatro hipóteses ao longo deste estudo. Uma hipótese geral e que aponta para uma influência do estado de saúde no bem-estar psicológico; a segunda hipótese confirma a moderação do variável apoio social percebido; a terceira hipótese confirma a mediação do variável estado emocional; e a última hipótese confirma a mediação das variável apoio social percebido e estado emocional em conjunto. Para cada hipótese foram analisados os dados sócio-demográficos. Trata-se de um estudo correlacionai, transversal e exploratório, com uma única avaliação. Foi desenvolvido com 200 indivíduos adultos em idade ativa, com idades compreendidas entre os 30 e os 64 anos, de ambos os sexos e residentes em Portugal Continental. No fim são apresentadas algumas limitações deste estudo, bem como os seus aspetos positivos e algumas sugestões para estudos futuros. ABSTRACT: This study aimed to investigate the relationship that perceptions of aging, health status and psychopathological symptoms have on psychological well-being, taking into account the influence of variables (moderating or mediating) as the perceived social support and emotional state. Four cases were dealt with during this study. A general hypothesis and aims to influence health status on psychological well-being; the second hypothesis confirms the moderating variable of perceived social support; the third event confirms the mediating variable of emotional state; and the last hypothesis confirms the mediating variables perceived social support and emotional state together. For each hypothesis we analyzed the socio-demographic dates. This is a correlational study, transversal and exploratory, with a single evaluation. Research was conducted with 200 adults of working age, aged between 30 and 64 years, of both sexes residing in Portugal. ln order to present some limitations of this study as well as its positive aspects and some suggestions for future studies.

Significações de envelhecimento, variáveis relacionais subjectivas e bem-estar psicológico em idosos

O presente estudo pretendia avaliar se as perceções de envelhecimento teriam influência no bem-estar psicológico dos idosos. Procurou-se compreender qual o efeito da influência (moderação ou mediação), das variáveis relacionais subjetivas: apoio social, religiosidade, perceção de saúde e estado emocional. O estudo foi realizado numa amostra portuguesa de 150 idosos, com idades compreendidas entre os 65 e os 99 anos. Foram utilizados dez instrumentos de avaliação. Os resultados mostram, que as perceções de envelhecimento, conjuntamente com a avaliação que as pessoas fazem do seu estado de saúde e dos sintomas psicopatológicos, predizem de forma significativa, a perceção do seu bem-estar psicológico. O apoio social e a religiosidade, são variáveis mediadoras, enquanto, a ansiedade existencial e o estado emocional, são moderadoras. Podemos verificar que existem diferenças significativas entre as diversas variáveis sócio-demográficas. Com o aumento da esperança de vida, pretende-se que este estudo contribua para a compreensão das dimensões pessoais intra e interindividuais do envelhecimento. ABSTRACT: The present study it intended to assess whether the perceptions of aging will impact on psychological well-being of the elderly. We tried to understand, what effect the influence (moderation or mediation), the relational subjective variables: social support, religiosity, health perception and emotional state. The study was conducted in a Portuguese sample of 150 elderly people, aged between 65 and 99 years. Ten instruments were used for evaluation. The results show that perceptions of aging, jointly with the assessment that people make in their state of health and psychopathology predict significantly the perception of their psychological well-being. Social support and religiosity, are mediating variables, while the existential anxiety and emotional state, they are moderating. We can see that there are significant differences between the various socio-demographic variables. With the increase of the life hope, it is intended that this study contributes to the understanding of intra and inter-personal dimensions of aging.

Le processus décisionnel sous-jacent à la rétroaction corrective des enseignants de français langue seconde à l'oral

L’objectif de cette étude qualitative est de décrire et de comprendre le processus décisionnel sous-jacent à la rétroaction corrective d’un enseignant de langue seconde à l’oral. Pour ce faire, elle décrit les principaux facteurs qui influencent la décision de procéder à une rétroaction corrective ainsi que ceux qui sous-tendent le choix d’une technique de rétroaction particulière. Trois enseignantes de français langue seconde auprès d’un public d’adultes immigrants au Canada ont participé à cette recherche. Des séquences complètes d’enseignement ont été filmées puis présentées aux participantes qui ont commenté leur pratique. L’entretien de verbalisation s’est effectué sous la forme d’un rappel stimulé et d’une entrevue. Cet entretien constitue les données de cette étude. Les résultats ont révélé que la rétroaction corrective ainsi que le choix de la technique employée étaient influencés par des facteurs relatifs à l’erreur, à l’apprenant, au curriculum, à l’enseignant et aux caractéristiques des techniques. Ils ont également révélé que l’apprenant est au cœur du processus décisionnel rétroactif des enseignants de langue seconde. En effet, les participantes ont affirmé vouloir s’adapter à son fonctionnement cognitif, à son état affectif, à son niveau de langue et à la récurrence de ses erreurs. L’objectif de cette étude est d’enrichir le domaine de la formation initiale et continue des enseignants de L2. Pour cela, des implications pédagogiques ont été envisagées et la recommandation a été faite de porter à la connaissance des enseignants de L2 les résultats des recherches sur l’efficacité des techniques de rétroaction corrective, particulièrement celles qui prennent en compte les caractéristiques des apprenants.

Baran: an interaction-centred user monitoring framework

User Quality of Experience (QoE) is a subjective entity and difficult to measure. One important aspect of it, User Experience (UX), corresponds to the sensory and emotional state of a user. For a user interacting through a User Interface (UI), precise information on how they are using the UI can contribute to understanding their UX, and thereby understanding their QoE. As well as a user’s use of the UI such as clicking, scrolling, touching, or selecting, other real-time digital information about the user such as from smart phone sensors (e.g. accelerometer, light level) and physiological sensors (e.g. heart rate, ECG, EEG) could contribute to understanding UX. Baran is a framework that is designed to capture, record, manage and analyse the User Digital Imprint (UDI) which, is the data structure containing all user context information. Baran simplifies the process of collecting experimental information in Human and Computer Interaction (HCI) studies, by recording comprehensive real-time data for any UI experiment, and making the data available as a standard UDI data structure. This paper presents an overview of the Baran framework, and provides an example of its use to record user interaction and perform some basic analysis of the interaction.

Test of Emotion Comprehension: Exploring the underlying structure through Confirmatory Factor Analysis and Similarity Structure Analysis

Some decades of research on emotional development have underlined the contribution of several domains to emotional understanding in childhood. Based on this research, Pons and colleagues (Pons & Harris, 2002; Pons, Harris & Rosnay, 2004) have proposed the Test of Emotion Comprehension (TEC) which assesses nine domains of emotional understanding, namely the recognition of emotions, based on facial expressions; the comprehension of external emotional causes; impact of desire on emotions; emotions based on beliefs; memory influence on emotions; possibility of emotional regulation; possibility of hiding an emotional state; having mixed emotions; contribution of morality to emotional experiences. This instrument was administered individually to 182 Portuguese children aged between 8 and 11 years, of 3rd and 4th grades, in public schools. Additionally, we used the Socially in Action-Peers (SAp) (Rocha, Candeias & Lopes da Silva, 2012) to assess TEC’s criterion-related validity. Mean differences results in TEC by gender and by socio-economic status (SES) were analyzed. The results of the TEC’s psychometric analysis were performed in terms of items’ sensitivity and reliability (stability, test-retest). Finally, in order to explore the theoretical structure underlying TEC a Confirmatory Factor Analysis and a Similarity Structure Analysis were computed. Implications of these findings for emotional understanding assessment and intervention in childhood are discussed.

Integrating an Emotion Recognition Model for the Flobi System

This thesis investigates if emotional states of users interacting with a virtual robot can be recognized reliably and if specific interaction strategy can change the users’ emotional state and affect users’ risk decision. For this investigation, the OpenFace [1] emotion recognition model was intended to be integrated into the Flobi [2] system, to allow the agent to be aware of the current emotional state of the user and to react appropriately. There was an open source ROS [3] bridge available online to integrate OpenFace to the Flobi simulation but it was not consistent with some other projects in Flobi distribution. Then due to technical reasons DeepFace was selected. In a human-agent interaction, the system is compared to a system without using emotion recognition. Evaluation could happen at different levels: evaluation of emotion recognition model, evaluation of the interaction strategy, and evaluation of effect of interaction on user decision. The results showed that the happy emotion induction was 58% and fear emotion induction 77% successful. Risk decision results show that: in happy induction after interaction 16.6% of participants switched to a lower risk decision and 75% of them did not change their decision and the remaining switched to a higher risk decision. In fear inducted participants 33.3% decreased risk 66.6 % did not change their decision The emotion recognition accuracy was and had bias to. The sensitivity and specificity is calculated for each emotion class. The emotion recognition model classifies happy emotions as neutral in most of the time.

Neural activity changes to emotional stimuli in healthy individuals under chronic use of clomipramine

Previous functional magnetic resonance imaging (fMRI) studies examined neural activity responses to emotive stimuli in healthy individuals after acute/subacute administration of antidepressants. We now report the effects of repeated use of the antidepressant clomipramine on fMRI data acquired during presentation of emotion-provoking and neutral stimuli on healthy volunteers. A total of 12 volunteers were evaluated with fMRI after receiving low doses of clomipramine for 4 weeks and again after 4 weeks of washout. Fear-, happiness-, anger-provoking and neutral pictures from the International Affective Picture System (IAPS) were used. Data analysis was performed with statistical parametric mapping (P < 0.05). Paired t-test comparisons for each condition between medicated and unmedicated states showed, to negative valence paradigms, decrease in brain activity in the amygdala when participants were medicated. We also demonstrated, across both positive and negative valence paradigms, consistent decreases in brain activity in the medicated state in the anterior cingulate gyrus and insula. This is the first report of modulatory effects of repeated antidepressant use on the central representation of somatic states in response to emotions of both negative and positive valences in healthy individuals. Also, our results corroborate findings of antidepressant-induced temporolimbic activity changes to emotion-provoking stimuli obtained in studies of subjects treated acutely with such agents.

Elevated Amygdala Activity to Sad Facial Expressions: A State Marker of Bipolar but Not Unipolar Depression

Background: Difficulties in emotion processing and poor social function are common to bipolar disorder (BD) and major depressive disorder (MDD) depression, resulting in many BID depressed individuals being misdiagnosed with MDD. The amygdala is a key region implicated in processing emotionally salient stimuli, including emotional facial expressions. It is unclear, however, whether abnormal amygdala activity during positive and negative emotion processing represents a persistent marker of BD regardless of illness phase or a state marker of depression common or specific to BID and MDD depression. Methods: Sixty adults were recruited: 15 depressed with BID type 1 (BDd), 15 depressed with recurrent MDD, 15 with BID in remission (BDr), diagnosed with DSM-IV and Structured Clinical Interview for DSM-IV Research Version criteria; and 15 healthy control subjects (HC). Groups were age- and gender ratio-matched; patient groups were matched for age of illness onset and illness duration; depressed groups were matched for depression severity. The BDd were taking more psychotropic medication than other patient groups. All individuals participated in three separate 3T neuroimaging event-related experiments, where they viewed mild and intense emotional and neutral faces of fear, happiness, or sadness from a standardized series. Results: The BDd-relative to HC, BDr, and MDD-showed elevated left amygdala activity to mild and neutral facial expressions in the sad (p < .009) but not other emotion experiments that was not associated with medication. There were no other significant between-group differences in amygdala activity. Conclusions: Abnormally elevated left amygdala activity to mild sad and neutral faces might be a depression-specific marker in BID but not MDD, suggesting different pathophysiologic processes for BD versus MDD depression.

Abnormal Left and Right Amygdala-Orbitofrontal Cortical Functional Connectivity to Emotional Faces: State Versus Trait Vulnerability Markers of Depression in Bipolar Disorder

Background: Amygdala-orbitofrontal cortical (OFC) functional connectivity (FC) to emotional stimuli and relationships with white matter remain little examined in bipolar disorder individuals (BD). Methods: Thirty-one BD (type 1; n = 17 remitted; n = 14 depressed) and 24 age- and gender-ratio-matched healthy individuals (HC) viewed neutral, mild, and intense happy or sad emotional faces in two experiments. The FC was computed as linear and nonlinear dependence measures between amygdala and OFC time series. Effects of group, laterality, and emotion intensity upon amygdala-OFC FC and amygdala-OFC FC white matter fractional anisotropy (FA) relationships were examined. Results: The BD versus HC showed significantly greater right amygdala-OFC FC (p <= .001) in the sad experiment and significantly reduced bilateral amygdala-OFC FC (p = .007) in the happy experiment. Depressed but not remitted female BD versus female HC showed significantly greater left amygdala-OFC FC (p = .001) to all faces in the sad experiment and reduced bilateral amygdala-OFC FC to intense happy faces (p = .01). There was a significant nonlinear relationship (p = .001) between left amygdala-OFC FC to sad faces and FA in HC. In BD, antidepressants were associated with significantly reduced left amygdala-OFC FC to mild sad faces (p = .001). Conclusions: In BD, abnormally elevated right amygdala-OFC FC to sad stimuli might represent a trait vulnerability for depression, whereas abnormally elevated left amygdala-OFC FC to sad stimuli and abnormally reduced amygdala-OFC FC to intense happy stimuli might represent a depression state marker. Abnormal FC measures might normalize with antidepressant medications in BD. Nonlinear amygdala-OFC FC-FA relationships in BID and HC require further study.

Effect of mindfulness meditation on the neural substrates of emotion processing and resting state in experienced and beginner meditators

La méditation par le ‘mindfulness’ favorise la stabilité émotionelle, mais les mécanismes neuroneux qui sous-tendent ces effets sont peu connus. Ce projet investiga l’effet du ‘mindfulness’ sur les réponses cérébrales et subjectives à des images négatives, positives et neutres chez des méditants expérimentés et des débutants au moyen de l’imagerie par résonance magnétique fonctionnelle (IRMf). Le ‘mindfulness’ atténua l’intensité émotionelle via différents mécanismes cérébraux pour chaque groupe. Comparés aux méditants, les débutants manifestèrent une déactivation de l’amygdale en réponse aux stimuli émotifs durant le ‘mindfulness’. Comparés aux débutants, les méditants exhibèrent une déactivation de régions du réseau du mode par défaut (RMD) pendant le ‘mindfulness’ pour tous stimuli (cortex médian préfrontal [CMP], cortex cingulaire postérieur [CCP]). Le RMD est constitué de régions fonctionnellement connectées, activées au repos et déactivées lors de tâches explicites. Cependant, nous ne connaissons pas les impacts de l’entraînement par la méditation sur la connectivité entre régions du RMD et si ces effets persistent au-delà d’un état méditatif. La connectivité fonctionnelle entre régions du RMD chez les méditants et débutants au repos fut investiguée au moyen de l’IRMf. Comparés aux débutants, les méditants montrèrent une connectivité affaiblie entre subdivisions du CMP, et une connectivité accrue entre le lobule pariétal inférieur et trois regions du RMD. Ces résultats reflètent que les bienfaits immédiats du ‘mindfulness’ sur la psychopathologie pourraient être dûs à une déactivation de régions limbiques impliquées dans la réactivité émotionelle. De plus, les bienfaits à long-terme de la méditation sur la stabilité émotionelle pourrait être dûs à une déactivation de régions corticales et cingulaires impliquées dans l’évaluation de la signification émotive et une connectivité altérée entre régions du RMD à l’état de repos.

Negative bias of processing ambiguously cued emotional stimuli.

Daily we cope with upcoming potentially disadvantageous events. Therefore, it makes sense to be prepared for the worst case. Such a 'pessimistic' bias is reflected in brain activation during emotion processing. Healthy individuals underwent functional neuroimaging while viewing emotional stimuli that were earlier cued ambiguously or unambiguously concerning their emotional valence. Presentation of ambiguously announced pleasant pictures compared with unambiguously announced pleasant pictures resulted in increased activity in the ventrolateral prefrontal, premotor and temporal cortex, and in the caudate nucleus. This was not the case for the respective negative conditions. This indicates that pleasant stimuli after ambiguous cueing provided 'unexpected' emotional input, resulting in the adaptation of brain activity. It strengthens the hypothesis of a 'pessimistic' bias of brain activation toward ambiguous emotional events.
