Background: Some aircraft collisions have been partly attributed to the cry wolf effect, and in other domains (health care and systems monitoring), there is a causal connection between false-alarm rate and cry wolf behavior. We hypothesized that a corresponding relationship exists in air traffic control (ATC). Method: Aircraft track and alert system behavior data surrounding 495 conflict alerts were analyzed to identify true and false alerts, trajectory type, and controller behavior. Forty-five percent of the alerts were false, ranging from 0.28 to 0.58. Results: Although centers with more false alerts contributed to more nonresponses, there was no evidence that these were nonresponses to true alerts or that response times were delayed in those centers. Instead, controllers showed desirable anticipatory behavior by issuing trajectory changes prior to the alert. Those trajectory pairs whose conflicts were more difficult to visualize induced more reliance on, and less compliance with, the alerting system. Conclusion: The high false-alarm rate does not appear to induce cry wolf behavior in the context of en route ATC conflict alerts. Application: There is no need to substantially modify conflict alert algorithms, but the conflict alert system may be modified to address difficult-to-visualize conflicts. <\/jats:p>","DOI":"10.1177\/0018720809344720","type":"journal-article","created":{"date-parts":[[2009,9,17]],"date-time":"2009-09-17T02:39:45Z","timestamp":1253155185000},"page":"446-462","source":"Crossref","is-referenced-by-count":86,"title":["False Alerts in Air Traffic Control Conflict Alerting System: Is There a \u201cCry Wolf\u201d Effect?"],"prefix":"10.1177","volume":"51","author":[{"given":"Christopher D.","family":"Wickens","sequence":"first","affiliation":[{"name":"Alion Science Corporation, Boulder, Colorado,"}]},{"given":"Stephen","family":"Rice","sequence":"additional","affiliation":[{"name":"New Mexico State University, Las Cruces, New Mexico"}]},{"given":"David","family":"Keller","sequence":"additional","affiliation":[{"name":"New Mexico State University, Las Cruces, New Mexico"}]},{"given":"Shaun","family":"Hutchins","sequence":"additional","affiliation":[{"name":"Alion Science Corporation"}]},{"given":"Jamie","family":"Hughes","sequence":"additional","affiliation":[{"name":"New Mexico State University, Las Cruces, New Mexico"}]},{"given":"Krisstal","family":"Clayton","sequence":"additional","affiliation":[{"name":"New Mexico State University, Las Cruces, New Mexico"}]}],"member":"179","published-online":{"date-parts":[[2009,9,16]]},"reference":[{"key":"atypb1","volume-title":"Auditory alarms in airways facilities environment (DOT\/FAA\/CT-TN04\/04)","author":"Ahlstrom, V.","year":"2003"},{"key":"atypb2","volume-title":"Human factors analysis of safety alerts in air traffic control (Final Report DOT\/FAA 07\/22)","author":"Allendoerfer, K.","year":"2007"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1175\/WAF1031.1"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1207\/S15327108IJAP1303_04"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1080\/001401300421743"},{"key":"atypb6","volume-title":"Cry-wolf: The psychology of false alarms","author":"Breznitz, S.","year":"1983"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ssci.2005.09.004"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1518\/001872006778606822"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1518\/001872007X215656"},{"key":"atypb10","volume-title":"Proceedings of the Human Factors and Ergonomics Society 49th Annual Meeting","author":"Dixon, S.R."},{"key":"atypb11","volume-title":"Common ARTS computer program functional specification for conflict alerts (NAS-MD-632)","author":"Federal Aviation Administration .","year":"2003"},{"key":"atypb12","volume-title":"Human Factors Study of Air Traffic Control Safety Alerts white paper and progress report","author":"Federal Aviation Administration .","year":"2006"},{"key":"atypb13","volume-title":"Proceedings of the 52nd Annual Meeting of the Human Factors and Ergonomics Society","author":"Friedman-Berg, F."},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1037\/1076-898X.1.1.19"},{"key":"atypb15","volume-title":"Signal detection theory and psychophysics","author":"Green, D.M.","year":"1966"},{"key":"atypb16","volume-title":"Alerting systems and how to address the lack of base rate information.
