    • Abstract:
      Objectives: 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 cooperative （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 average 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.
      Conclusions: Eye movement can be an objective index for the primary judgment of cooperation level.
