In order to solve the existing problem of the combination of traffic signs at typical grassland highway intersections, the combination setting of intersection traffic engineering facilities was optimized. Through simulation experiments, the electroencephalogram (EEG) signals of 40 drivers were collected, clustered into 5 (MS1—MS5) microstate topographic maps, and the reaction time and duration, coverage, frequency of occurrence and conversion probability of the drivers were statistically analyzed. The experimental results showed that the default network and the dorsal attention network in the driver's EEG microstate played a major role in the cognitive process of the combination of traffic facilities at the grassland highway intersection. The duration of MS4 and the conversion probability of MS1—MS3 increased with the increase of transportation facilities, which can be used as direct indicators to evaluate driver's cognitive load. Microstate indicators and reaction time trend analysis found that at the information level C, that was, the combination of four traffic engineering facilities, the driver's brain state had the best performance, the strongest cognitive ability, the smaller load and the fastest response.

The tough noise environment in helicopter cockpit can passively influence pilots in mental and physical way, weaken their core competency, and as a result, maybe causing pilot error and even accidents. The current research can evaluate the physical characteristics of noise and its impact on emotion such as noise annoyance, but it ignores the impact of cockpit noise on human competence. Therefore, this paper establishes a noise evaluation and prediction model based on core competence with task performance, cognitive load and eye movement data. Experiment is designed and implemented in three noise levels and three task difficulties to verify the model. The results indicate that: 1) core competency and task accuracy decline in higher noise levels significantly. 2) the noise assessment method based on core competency can accurately predict the influence of noise on human performance. This novel method can quantitatively reflect the impact of noise changes on human performance in emergency condition. It can expand the connotation of noise evaluation, provide the evaluation and control of cockpit noise with theoretical explanations, and provide the optimization design of helicopter cockpit with practical data.

BACKGROUND: Maintaining postural stability during walking is critical for the prevention of falls, and how dynamic stability alters during cognitive dual-task walking remains controversial. OBJECTIVE: To explore the influence of cognitive load factors on posture control performance of dual-task research paradigm by comparing the differences of dynamic stability during walking under four different cognitive loads, and to provide theoretical basis for dynamic stability rehabilitation training. METHODS: The Motion three-dimensional motion capture system was used to collect the kinematic data of 16 male college students during walking under different cognitive loads (zero load, one load, double load and triple load), and the dynamic stability margin was calculated indirectly through the kinematic data. Among them, cognitive single-task walking refers to walking + zero times cognitive load; cognitive dual-task walking refers to walking + one, two, and three times cognitive load. Univariate repeated measure analysis of variance was used to compare the differences of gait parameters and dynamic stability under different cognitive loads. RESULTS AND CONCLUSION: (1) Compared with zero load, walking speed and dynamic stability margin of other cognitive loads were decreased (P < 0.05). (2) Walking speed and step length of double cognitive load were lower than those of one cognitive load (P < 0.05). The step length of double cognitive load was lower than that of zero cognitive load (P < 0.05). (3) Step width parameters had no statistical significance when walking under different cognitive loads (P > 0.05). (4) It is indicated that with the increase of cognitive load, young adults responded to the intervention of cognitive task mainly by decreasing stride speed and stride length and changing gait pattern. During dual-task walking, the intervention of cognitive task did not affect step width parameters, and it is not recommended to use step width parameters as an effective indicator to evaluate the performance of dual-task posture control when evaluating the effectiveness of dual-task rehabilitation training program. When the cognitive load did not exceed the total attention resources of the human body, the intervention of cognitive task increased the dynamic stability of the left and right directions during walking. For young people, different cognitive loads have little influence on postural control, and the setting of cognitive load can be appropriately reduced when implementing dual-task rehabilitation intervention.
