Abstract
The aims of the study were to collect normative CS data on naval personnel, to investigate any changes in CS due to normal watchkeeping tasks, and to evaluate CS as a potential predictor of visual watchkeeping ability. CS measures were taken on 215 CF naval personnel onboard the destroyer HMCS Saguenay, using VISTECH Vision Contrast Test System (VCTS) Model 6500 charts. A subpopulation of 18 bridge and 19 operations room watchkeepers were tested before and after a normal four hour watch period. Finally, supervisors completed questionnaires in order to provide a subjective measure of watchkeepers' performance. No significant changes in CS were found over watch periods. CS alone was a poor predictor of watchkeeping performance as assessed by supervisors. The results of the study show no advantage to using CS as a predictive measure of watchkeeping abilities.
