Abstract: 摘要 模拟飞行员在飞行过程中监视仪表信息的过程,分析脑电(EEG)随脑力疲劳变化的特点及规律,从而为后期对抗脑力疲劳提供科学根据。通过设计2级不同难度的视觉监控任务分别诱发脑力疲劳,采用多种方法相结合进行研究,比较EEG参数(δ、θ、α、β、(α+θ)/β、α/β、(α+θ)/(α+β)和 θ/β)在任务前后的变化情况。结果表明:从正常到疲劳状态,额区、中央区、顶区和枕区的α波相对能量显著增加(P < 0.05);前额区、侧额区、后颞区以及枕区的β波相对能量显著降低(P < 0.05);δ波和θ波相对能量变化未达到显著性差异(均有P > 0.05);参数(α+θ)/β、α/β、(α+θ)/(α+β)和θ/β在除颞区外的各脑区都显著增大(P < 0.05);在颞区,只有α/β在疲劳前后增加明显(P < 0.05);与较高难度的任务比较,低难度任务中的各EEG参数变化较为明显。因此,除δ波和θ波以外的其他特征参数被证实在特定的脑区域可以作为衡量脑力疲劳的潜在指标,同时可以验证适当地增加任务难度可以在某种程度上对抗脑力疲劳的产生。
Abstract:By simulating the process of pilots monitoring instrument information during flight,the change characteristics of electroencephalogram (EEG) waves along with mental fatigue were analyzed,which will provide scientific bases for future development of countermeasure to fatigue.Two visual detection tasks of different difficulties were designed to induce fatigue respectively,and many measurements were combined to study the EEG characteristics of fatigue.The EEG parameters [δ,θ,α,β,(α+θ)/β,α/β,(α+θ)/(α+β),θ/β] at the beginning and end sections of the task were compared and analyzed.The results show that there is a significant increase in α activity in the frontal,central,parietal and occipital lobes(P < 0.05),and a decrease in the β activity in the pre-frontal,inferior frontal,posterior temporal and occipital lobes(P < 0.05); there is no significant difference in δ rhythm and θ rhythm in any brain region(all in P > 0.05); The four formulas increase significantly in all brain regions except the temporal(P < 0.05),where only α/β changes clearly(P < 0.05); compared with the task with higher difficulty,the parameters in the task of lower difficulty change more obviously.Therefore,all these characteristic parameters in specific brain regions except for δ and θ can be considered as possible indicators for mental fatigue.It was also verified that adding right amount of task difficulty could counter mental fatigue.

Abstract: 摘要 对飞行员在飞行中通过视觉搜索监视各种仪表信息的过程进行研究,探索时间压力和搜索难度两个因素对视觉搜索绩效的影响,从而为飞机座舱显示界面的工效学设计提供科学依据.设计视觉搜索程序来模拟飞机显示界面,并通过预实验确定时间压力水平和搜索难度水平的典型分级范围,在此基础上进行正式实验并记录反应正确率和反应时间.采用SPSS 19.0对实验结果进行双因素分析、简单效应、回归分析等,得到如下结论:不同水平的时间压力和搜索难度对反应正确率的影响具有显著性差异;不同水平的搜索难度对反应时间的影响具有显著性差异,并且在一定条件下反应时间和干扰项数目成线性递增关系;在保证较高正确率的状态下,即在人的认知能力范围之内,不同的时间压力水平对反应时间的影响没有显著性差异.因此,在飞机座舱显示界面视觉搜索的工效学设计中,要将时间压力和搜索难度进行最佳匹配才能取得较好的工作绩效.
Abstract: Pilots monitor all kinds of instrument information by visual searching during flight. This process was studied to explore the effects of time pressure and search difficulty on visual searching, aiming to provide scientific basis for the ergonomic design of display interface of aircraft cockpit. A visual searching program was designed to simulate the display interface. Before conducting formal experiment, the classified ranges of time pressure and searching difficulty were evaluated by pre-experiment. Using SPSS 19.0, analyses such as double factor variance analysis, simple main effect, and regression analysis were conducted on the response correct rate and response time obtained by the formal experiment. The following conclusions were obtained, different levels of time pressure and search difficulty all have significant effect on the response accurate rate; search difficulty has obvious effect on the response time which has a linearly increasing relationship with distractor number; under high correct rate situation, that is within the human cognitive abilities, time pressure haven't such effect on the response time. In ergonomical study of display interface in plane cockpit, good match of time pressure and searching difficulty could obtain better searching performance.

Abstract: 大脑皮层网络有向功能连通性是理解大脑组织行为活动方式的关键。本文探索步枪射击任务中射手大脑网络在脑电信号不同节律下的有向功能连通性,为加速步枪射击训练方法的研究提供神经科学方面的依据。采用扩展概率性因果方法分析步枪射击专家和新手在射击准备(pre-shot)阶段大脑皮层的有效定向功能连接。结果表明,额区、额-中、中央区、顶区和枕区在射击过程中都被激活,并且大脑右半球功能连接数量明显多于左半球。在 pre-shot 阶段,与专家相比较,新手大脑皮层网络参与活动的脑区明显增多、网络节点间的连接强度更大、全局效率值较低。这些结果间接地证明了新手需要更努力地协调更多的资源来完成任务,这与专家功能性脑组织的“神经效率”假说一致。
The directed functional connectivity in cerebral cortical is the key to understanding the pattern of the behavioral tissue. This process was studied to explore the directed functional network of rifle shooters at cerebral cortical rhythms from electroencephalogram (EEG) data, aiming to provide neurosciences basis for the future development of accelerating rifle skill learning method. The generalized orthogonalized partial directed coherence (gOPDC) algorithm was used to calculate the effective directed functional connectivity of the experts and novices in the pre-shot period. The results showed that the frontal, frontal-central, central, parietal and occipital regions were activated. Moreover, the more directed functional connections numbers in right hemispheres were observed compared to the left hemispheres. Furthermore, as compared to experts, novices had more activated regions, the stronger strength of connections and the lower value of the global efficiency during the pre-shot period. Those indirectly supported the conclusion that the novices needed to recruit more brain resources to accomplish tasks, which was consistent with " neural efficiency” hypothesis of the functional cerebral cortical in experts.

Abstract: 本文主要探讨多目标搜索过程中目标搜索时间的规律和眼动行为特征。试验任务由计算机编程实现,并将字符呈现在 1 个 24 英寸的显示器上,任务要求受试者在呈现的字符中找出 3 个目标字符,同一组的 3 个目标字符之间具有较高的相似度,而不同组的目标字符和干扰字符之间具有不同的相似度。试验过程中记录了搜索时间数据和眼动数据。结果表明,目标字符与干扰字符相似度较高时注视点数量也较多;受试者在搜索过程中主要有三种眼动模式,即平行搜索模式、系列搜索模式和平行-系列搜索模式,且平行-系列搜索模式具有最好的搜索绩效,即使用平行-系列搜索模式的受试者所用的时间最短;目标呈现的顺序对于搜索绩效有明显影响;目标字符与干扰字符之间的相似度也会影响搜索绩效。
The aim of this study is to investigate the search time regulation of objectives and eye movement behavior characteristics in the multi-objective visual search. The experimental task was accomplished with computer programming and presented characters on a 24 inch computer display. The subjects were asked to search three targets among the characters. Three target characters in the same group were of high similarity degree while those in different groups of target characters and distraction characters were in different similarity degrees. We recorded the search time and eye movement data through the whole experiment. It could be seen from the eye movement data that the quantity of fixation points was large when the target characters and distraction characters were similar. There were three kinds of visual search patterns for the subjects including parallel search, serial search, and parallel-serial search. In addition, the last pattern had the best search performance among the three search patterns, that is, the subjects who used parallel-serial search pattern spent shorter time finding the target. The order that the targets presented were able to affect the search performance significantly; and the similarity degree between target characters and distraction characters could also affect the search performance.

刑事政策视野中犯罪未完成形态立法模式的理性建构

法学家 , 2012,
Abstract: 犯罪未完成形态的立法模式是客观主义犯罪观和主观主义犯罪观在犯罪未完成形态上的立法体现。犯罪未完成形态立法模式不仅决定着犯罪圈的大小,而且征表和反映了国家的刑事政策取向和对不同行为的刑事政策态度。中国现行犯罪未完成形态立法模式的主要缺陷是刑法总则的立法模式与分则的犯罪构成模式相矛盾;刑事立法对犯罪预备行为处罚的泛化和刑事司法对犯罪预备行为处罚的异化致使罪刑法定原则受到挑战;刑事立法对犯罪未遂行为处罚的主观化不当地扩张了可罚的未遂行为的范围。中国对犯罪未完成形态的立法模式应当进行如下改革犯罪预备行为处罚的例外化;犯罪未遂行为处罚的客观化;犯罪中止行为认定的合理化。
