Background: Interoception and heart rate variability have been found to predict outcomes of mental health and well-being. However, these have usually been investigated independently of one another. Objectives: This systematic review aimed to explore a key gap in the current literature, that being, identifying whether HRV and interoception predict emotional regulation outcomes and strategies. Methods: The process of article retrieval and selection followed the PRISMA guidelines. Databases PsychINFO, Web of Science, PubMed, CINAHL, and MEDLINE were scanned for papers published. Preliminary inclusion and exclusion criteria were specified following the PICO framework, whilst the CHARMS framework was used to help formulate the research question, and critically assess for bias. Results: Two hundred and thirty-seven studies were identified after initial database searches. Of these, eight studies were included in the final selection. Six studies explored the associations between HRV and ER, whilst three investigated the associations between interoception and ER (one study included both). Results show that greater HRV and interoception are associated with better ER. Specifically, high parasympathetic activity largely predicted the use of adaptive ER strategies such as reappraisal, and better acceptance of emotions. High interoception, instead, was predictive of effective downregulation of negative emotions and handling of social uncertainty, there was no association with any specific ER strategy. Conclusions: Awareness of one's own bodily feelings and vagal activation seem to be of central importance for the effective regulation of emotional responses. However, one limitation is the small sample of studies found, thus more studies in this area are needed in the future.
La prévision des crues est souvent réalisée au pas de temps horaire, qui est un bon compromis entre disponibilité des données et résolution nécessaire pour bien rendre compte des phénomènes de crue. Cependant, dans un certain nombre de cas, ce pas de temps fixe est limitant, et des pas de temps plus fins (ou éventuellement plus larges) sont mieux adaptés. Il est donc nécessaire d'avoir des modèles hydrologiques capables de s'adapter à un fonctionnement à différents pas de temps. Or, cette adaptation ne se résume généralement pas à un simple changement de la longueur du pas de temps dans les équations du modèle. Elle implique une explicitation de la dépendance possible de certains paramètres du modèle au pas de temps, et également une adaptation de la structure du modèle pour que les processus soient représentés de manière cohérente entre les pas de temps. L'article présente une adaptation du modèle hydrologique GRP, qui est largement utilisé en conditions opérationnelles par les services de prévision des crues français, pour qu'il fonctionne correctement à différents pas de temps. Les tests sont réalisés sur une base de 240 bassins versants français.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
