In the present study, we examined the role of vagal tone in predicting the ability to delay gratification in both resource-rich and resource-poor environments. We derived hypotheses from evolutionary models of children\u2019s conditional adaptation to proximal rearing contexts. In Study 1, we tested whether elevated vagal tone was associated with shorter delay of gratification in impoverished children. In Study 2, we compared the relative role of vagal tone across two groups of children, one that had experienced greater impoverishment and one that was relatively middle-class. Results indicated that in resource-rich environments, higher vagal tone was associated with longer delay of gratification. In contrast, high vagal tone in children living in resource-poor environments was associated with reduced delay of gratification. We interpret the results with an eye to evolutionary-developmental models of the function of children\u2019s stress-response system and adaptive behavior across varying contexts of economic risk.<\/jats:p>","DOI":"10.1177\/0956797616640269","type":"journal-article","created":{"date-parts":[[2016,4,27]],"date-time":"2016-04-27T00:38:47Z","timestamp":1461717527000},"page":"885-893","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":82,"title":["Vagal Tone and Children\u2019s Delay of Gratification"],"prefix":"10.1177","volume":"27","author":[{"given":"Melissa L.","family":"Sturge-Apple","sequence":"first","affiliation":[{"name":"Department of Clinical and Social Sciences in Psychology, University of Rochester"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer H.","family":"Suor","sequence":"additional","affiliation":[{"name":"Department of Clinical and Social Sciences in Psychology, University of Rochester"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick T.","family":"Davies","sequence":"additional","affiliation":[{"name":"Department of Clinical and Social Sciences in Psychology, University of Rochester"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dante","family":"Cicchetti","sequence":"additional","affiliation":[{"name":"Institute of Child Development, University of Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Skibo","sequence":"additional","affiliation":[{"name":"Psychology Department, Westchester Community College"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fred A.","family":"Rogosch","sequence":"additional","affiliation":[{"name":"Mt.
