【摘要】：為探究人的腦力疲勞對其視覺選擇性注意的影響,開展監(jiān)控作業(yè)系統(tǒng)人機工效設計試驗。以32名男性為被試,采用140 min記憶刷新試驗任務(2-back任務)模擬監(jiān)控作業(yè)誘發(fā)腦力疲勞,然后采用2×3因素設計的中心線索提示范式模擬自動告警測量選擇性注意能力,通過分析行為學及腦電(EEG)數(shù)據(jù),研究腦力疲勞對視覺選擇性注意的影響。結(jié)果表明:140 min 2-back任務誘發(fā)了腦力疲勞,腦力疲勞狀態(tài)下,中心線索提示范式中的無效線索和目標刺激的疲勞效應最強,有效線索和干擾刺激的疲勞效應最弱,被試的選擇性注意任務績效下降、P300潛伏期顯著延長、幅值顯著減小,腦力疲勞對視覺選擇性注意能力有負性影響。
[Abstract]:In order to investigate the effect of mental fatigue on visual selective attention, a man-machine ergonomics design experiment was carried out in a monitoring operation system. 32 men were selected to simulate the mental fatigue induced by monitoring operation by using 140 min memory refresh test task and 2-back task. Then the central cue-cue paradigm designed by 2 脳 3 factors was used to simulate the automatic alarm to measure selective attention ability, and the behavioral and EEG data were analyzed. The effects of brain fatigue on visual selective attention were studied. The results showed that the brain fatigue was induced by the task: 140 min 2-back. Under the condition of mental fatigue, the ineffectual cues in the central cue paradigm and the fatigue effects of target stimulation were the strongest. The fatigue effect of effective cues and interference stimuli was the weakest. The latency of P300 was significantly prolonged and the amplitude of P300 was significantly decreased. Mental fatigue had negative effect on the ability of visual selective attention.
