目的：建立一种新型的认知能力评价系统，用其进行重复测查时能有效地避免（消除）学习效应． 方法：采用普遍认可的量表，根据随机化原则编制计算机化测试系统，该系统与研究任务和对象相适应，测试程序规范，测试项目较多并可任意选择和组合，测试结果记录自动化． 为用户提供一种方便友善的人机界面． 结果： ５４ 名受试者相隔 ２ ｗ ｋ 的重测可靠性系数为０．６２ ～ ０．８５，符合设计要求；分半信度系数为０６５ ～ ０．８４，表明测试内部一致性较好；以 Ｎ Ｅ Ｓ Ｃ测试绩效作为效标，计算各项测验的效度相关系数为０．７７ ～ ０．８５，表明本系统与 Ｎ Ｅ Ｓ Ｃ有良好的相关性． 结论：本测试系统具有良好的信度和效度，为研究异常环境因素对认知能力影响提供了新的方法．
OBJECTIVE: To establish a new cognitive ability evaluation system, which can effectively avoid (eliminate) learning effects when it is used for repeated tests. Methods: According to the principle of randomization, a computerized testing system was established based on the principle of randomization. The system was adapted to the research task and object. The testing procedure was standardized, the testing items were more and could be chosen and combined arbitrarily, and the test result recording was automated. To provide users with a convenient and friendly man-machine interface. Results: The retest reliability of 54 subjects was 0.62 ~ 0.85 after 2 wk, which met the design requirements. The half reliability coefficient was 0.65 ~ 0.84, indicating that the internal consistency of the test was better than that of the test Good; to N E S C test performance as a criterion, the validity of the test correlation coefficient of 0.77 ~ 0.85, indicating that the system and N E S C have a good correlation. Conclusion: The test system has good reliability and validity, which provides a new method for studying the impact of abnormal environmental factors on cognitive ability.
