Le développement de la régulation émotionnelle de l’adolescence au vieillissement : Application d’un modèle dynamique des affects en lien avec la personnalité

Abstract : In literature a positivity effect, can be defined as increased positive affect and / or decrease negative affect in adulthood, is identified. Several models try to explain the positivity effect for different aspects of individuals (such as their motivation to feel good), the cognitive development and emotional regulation (through the use of emotional regulation strategies. Because this positivity effect may seem counter-intuitive at first. This work thesis focuses on four models: the socioemotional selectivity theory (Löckenhoff & Carstensen, 2004), selection-optimization-compensation in emotional regulation (Urry & Gross, 2010), the dynamic integration theory (Labouvie-Vief, 2003) or that the integration of strengths and vulnerabilities (Charles, 2010). Especially concerning the development of three processes related to emotional regulation: selection, efficiency and temporally use of regulation strategies. Two hypotheses are considered. The developmental hypothesis is individuals develop expertise with aging (from adolescence to elderly) in the use of strategies. That would be visible on the emotional regulation processes. The differential hypothesis focuses on individual differences in the positivity effect and the development of expertise in emotional regulation presented by the previous hypothesis. To contribute to a better understanding of the positivity effect considering the interindividual differences related to age and personality characteristics, data is collected in two different ways: first by experience sampling method over a period of two weeks, second by a questionnaire. The results reveal one pattern of positivity effect whatever personality characteristics. This positivity effect can be explained by a development of expertise of different functions in terms of regulation strategies including those privileged with advancing age. However, this expertise is not the same for everyone. Indeed, some will target the reduction of negative affect, while others target the increased positive affect. Overall, the results show a hedonic shift of emotional regulation aims. The discussion of results highlights the relevance of the differential approach in the study of the developmental phenomenon to positivity effect. This work shows the pertinence of daily survey approach and data analysis modelling, to account for the dynamic nature emotional regulation and its evolution.
