A navigation plotting task, modeled after actual shipboard navigation and plotting practices, was evaluated for inclusion in the Performance Evaluation Tests for Environmental Research (PETER) task battery. The differential stability of the 9-min self-paced task was examined independently in the laboratory and during a field study conducted at sea aboard three seagoing vessels. Repeated testing in both laboratory and field conditions showed that the percent correct metric was not reliable. After 10-15 practice trials, the total completion and total correct scores were found to meet minimum statistical stability and reliability criteria. Inclusion of the Navigation Plotting task in the PETER test battery is recommended given the task's direct operational validity, its demonstrated sensitivity to vessel motion and motion sickness, and the degree of statistical stability and reliability found with the total completion and total correct metrics.
一项仿照实际船上导航和绘图操作建立的导航绘图任务，被评估是否纳入环境研究性能评估测试（PETER）任务组。在实验室以及在三艘海船上进行的海上实地研究中，分别独立考察了这个9分钟自定进度任务的差异稳定性。在实验室和实地条件下的重复测试表明，正确率指标不可靠。经过10 - 15次练习试验后，发现总完成分数和总正确分数符合最低统计稳定性和可靠性标准。鉴于该任务具有直接的操作有效性、已证明的对船舶运动和晕船的敏感性，以及总完成分数和总正确分数所具有的统计稳定性和可靠性程度，建议将导航绘图任务纳入PETER测试任务组。
