摘　　要：目的探索脑外伤所致精神障碍被试不合作者和合作者间眼动特征的差异。方法选取39名需进行精神伤残鉴定者,应用二项必选数字记忆测验将被试分为合作组和不合作组。让被试进行成人韦氏智力测验中的图片填充试验,同时应用眼动追踪系统记录眼球活动轨迹,并分析注视、眼跳、瞳孔、眨眼等数据。结果合作组(10例)与不合作组(29例)在眼跳方面差异均具有统计学意义(P<0.05),其中不合作组眼跳的频率、时间、幅度、加速度均明显高于合作组,合作组的眼跳潜伏期则明显增加。两组仅注视离散总距离、平均距离和总时间差异存在统计学意义(P<0.05),注视平均时间、次数、频率等差异均无统计学意义(P>0.05)。合作组的眨眼频率高于不合作组。结论眼动可以作为初步判断合作程度的客观评定指标。Objective To explore the difference of eye movement characteristics between uncooperative and cooperative subjects with mental disorder after cerebral trauma. Methods Thirty-nine subjects which needed psychiatric impairment assessment were selected. According to the binomial forced-choice digit memory test （BFDMT）, all subjects were divided into cooperative and uncooperative groups. The subjects were asked to take the image completion test from Wechsler adult intelligence scale. Meanwhile,the data of eye movement track, fixation, saccade, pupil and blink were recorded by the track system of eye movement. Results There were significantly differences （P〈0.05） in the data of saccade between coopera-tive （10 cases） and uncooperative groups （29 cases）. The frequency, time, amplitude, acceleration of saccadic in uncooperative group were significantly higher than cooperation group. The saccade latencies of cooperation group increased more than uncooperative group. There was a significant difference （P〈0.05） in total discrete distance, average distance and total time of fixation between two groups, while the aver-age duration time, number and frequency of fixation had no significantly difference （P〉0.05） between two groups. And the blink frequency of cooperation group was higher than uncooperative group. Conclusion Eye movement can be an objective index for the primary judgment of cooperation level.
