摘　　要：目的提供一种军人心理测量客观指标——融合自然语义信息的视线跟踪时-空相似度算法。方法将心理测量中自评量表的自然语义信息与被试的视线跟踪数据相融合,提出视线跟踪时-空相似度算法,计算不同人群在问卷应答中视线跟踪差异,并进行视觉模式识别,从而实现军人心理测量中对目标人群的筛查。结果在军人心理测量中,采用本文提出的算法进行抑郁障碍高危人群筛查,实验结果表明被试在单个题目刺激作用下的平均抑郁障碍高危人群筛查准确率为80.13%,降维后的准确率为97.37%。结论本文验证了融合语义信息的视线跟踪时-空相似度在军人心理测量中的客观性和有效性,可作为辅助心理测量的客观指标。Objective To offer an objective index for military psychological measurement,eye-tracking spatiotemporal similarity algorithm fused with natural semantic information.Methods We combined the natural semantic information of self-rating scale with the eye-tracking data of the subjects,proposed the spatiotemporal similarity algorithm of eye-tracking,calculated the eye-tracking differences of different populations in questionnaire responses and analyzed the visual pattern recognition,so as to realize the screening of target population in military psychological measurement.Results In the military psychological measurement,the proposed algorithm was used to screen the high-risk population of depressive disorder.The experimental results showed that the average accuracy of screening the high-risk population of depressive disorder was 80.13%under the stimulation of a single question,and 97.37%after dimension reduction.Conclusion This paper verifies the objectivity and validity of the eye-tracking spatiotemporal similarity combined with semantic information in the military psychological measurement,which can be used as an objective index to assist psychological measurement.
