Background: To date, only a few studies have examined the effect of sleep loss on distributed team performance, and only one other to our knowledge has examined the relationship between sleep loss and social-motivational aspects of teams (Hoeksema-van Orden, Gaillard, &amp; Buunk, 1998). Method: Sixteen teams participated; each comprised 4 members. Three team members made threat assessments on a military surveillance task and then forwarded their judgments electronically to a team leader, who made a final assessment on behalf of the team. Results: Sleep loss had an antagonistic effect on team decision-making accuracy and decision time. However, the performance loss associated with fatigue attributable to sleep loss was mediated by being part of a team, as compared with performing the same task individually \u2014 that is, we found evidence of a \u201cmotivational gain\u201d effect in these sleepy teams. We compare these results with those of Hoeksema-van Orden et al. (1998), who found clear evidence of a \u201csocial loafing\u201d effect in sleepy teams. Conclusion: The divergent results are discussed in the context of the collective effort model (Karau &amp; Williams, 1993) and are attributable in part to a difference between independent and interdependent team tasks. Application: The issues and findings have implications for a wide range of distributed, collaborative work environments, such as military network-enabled operations.<\/jats:p>","DOI":"10.1518\/001872007x215728","type":"journal-article","created":{"date-parts":[[2007,7,21]],"date-time":"2007-07-21T13:06:14Z","timestamp":1185023174000},"page":"646-660","source":"Crossref","is-referenced-by-count":41,"title":["Effects of Sleep Loss on Team Decision Making: Motivational Loss or Motivational Gain?"],"prefix":"10.1177","volume":"49","author":[{"given":"Joseph V.","family":"Baranski","sequence":"first","affiliation":[{"name":"Defence Research and Development Canada, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan M.","family":"Thompson","sequence":"additional","affiliation":[{"name":"Defence Research and Development Canada, Toronto, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick M.
