{"doi":"10.1037/0003-066x.56.3.218","title":"The role of positive emotions in positive psychology: The broaden-and-build theory of positive emotions.","abstract":"In this article, the author describes a new theoretical perspective on positive emotions and situates this new perspective within the emerging field of positive psychology. The broaden-and-build theory posits that experiences of positive emotions broaden people's momentary thought-action repertoires, which in turn serves to build their enduring personal resources, ranging from physical and intellectual resources to social and psychological resources. Preliminary empirical evidence supporting the broaden-and-build theory is reviewed, and open empirical questions that remain to be tested are identified. The theory and findings suggest that the capacity to experience positive emotions may be a fundamental human strength central to the study of human flourishing.","journal":"American Psychologist","year":2001,"id":6199,"datarank":12.77311714812817,"base_score":9.552581649917311,"endowment":9.552581649917311,"self_citation_contribution":1.4328872474875969,"citation_network_contribution":11.340229900640573,"self_endowment_contribution":1.4328872474875969,"citer_contribution":11.340229900640573,"corpus_percentile":93.8,"corpus_rank":770,"citation_count":14080,"citer_count":183,"citers_with_citation_signal":183,"citers_with_endowment":183,"datacite_reuse_total":0,"is_dataset":false,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2001-03-01","authors":[{"id":58159,"name":"Barbara L.
