The majority of research has utilized fairly complex tasks with the goal of emulating \u2019real\u2010life\u2019 scenarios. Here, we use a Lottery Choice Task (LCT) which assesses risk and ambiguity preference for both decisions involving potential gains and those involving potential losses. We hypothesized that one night of sleep deprivation would make subjects more risk seeking in both gains and losses. Both a control group and an experimental group took the LCT on two consecutive days, with an intervening night of either sleep or sleep deprivation. The control group demonstrated that there was no effect of repeated administration of the LCT. For the experimental group, results showed significant interactions of night (normal sleep versus total sleep deprivation, TSD) by frame (gains versus losses), which demonstrate that following as little as 23\u2003h of TSD, the prototypical response to decisions involving risk is altered. Following TSD, subjects were willing to take more risk than they ordinarily would when they were considering a gain, but less risk than they ordinarily would when they were considering a loss. For ambiguity preferences, there seems to be no direct effect of TSD. These findings suggest that, overall, risk preference is moderated by TSD, but whether an individual is willing to take more or less risk than when well\u2010rested depends on whether the decision is framed in terms of gains or losses.<\/jats:p>","DOI":"10.1111\/j.1365-2869.2007.00591.x","type":"journal-article","created":{"date-parts":[[2007,8,18]],"date-time":"2007-08-18T04:14:03Z","timestamp":1187410443000},"page":"245-252","source":"Crossref","is-referenced-by-count":196,"title":["The effects of one night of sleep deprivation on known\u2010risk and ambiguous\u2010risk decisions"],"prefix":"10.1111","volume":"16","author":[{"given":"BENJAMIN S.","family":"MCKENNA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DAVID L.","family":"DICKINSON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HENRY J.","family":"ORFF","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SEAN P.
