对176名6-12岁认知功能正常小学生进行脑波超慢涨落平均功率分布与计算速度关系的研究。结果表明:(1)计算速度快组和计算速度慢组中各年龄组的脑区平均功率符合额低枕高的前后梯度。计算速度慢组的逆转百分率高于计算速度快组。(2)在各年龄组中,计算速度快组和慢组功率前后逆转百分率的差异主要反映在右脑,右脑功率前后梯度逆转在不同计算组之间差异较大。(3)在计算速度快组和慢组中,左脑平均功率都小于右脑平均功率。计算速度快组和慢组脑波功率左右逆转百分率的差异主要反映在后脑,后脑功率左右逆转在逆转总数上计算速度快组多于计算速度慢组。 相似文献

仪表数量与信号间隔时距对监视作业效绩的影响 总被引:1,自引:0,他引:1
用信号察觉反应时与信号误报率作指标 ,对监视作业中监视仪表数量与信号间隔时距对监视作业效绩的影响问题进行研究。结果表明 ,监视作业的效绩会随仪表增多和信号间隔时距增大而呈下降趋势。当监视仪表达到 8个时 ,监视作业的效绩会因负荷过重而明显下降。信号出现间隔时距增长时 ,会因警戒水平下降使监视仪表作业的效绩明显降低。 相似文献

In the era of digital intelligence, how to improve the behavioral quality of R&D team members by granting work autonomy and proposing corresponding work demands is a pressing issue in the transformation of organizational management into digital intelligence. Based on the conservation of resources theory, this study investigates the effects of the interactions among work time autonomy, work method autonomy, and different types of work demands on team members' creative behavior and taking charge. By analyzing the two-stage data of 233 paired samples of team members and leaders, the results showed that: Work time autonomy was significantly positively correlated with creative behavior and taking charge of team members, and work method autonomy was significantly positively correlated with creative behavior and taking charge of team members, while the interaction between work time autonomy and work method autonomy was significantly positively correlated with the team members' taking charge; the interactions among work time autonomy, work method autonomy and innovative job requirements positively affect team members' creative behavior and taking charge; while the interactions among work time autonomy, work method autonomy and high performance expectations negatively affect team members' taking charge. This study provides a way to realize scientific management in the period of digital intelligence transformation. 相似文献

People implicitly generalize the actions of known individuals in a social group to unknown members. However, actions have social goals and evaluative valences, and the extent to which actions with different valences (helpful and harmful) are implicitly generalized among group members remains unclear. We used computer animations to simulate social group actions, where helping and hindering actions were represented by aiding and obstructing another's climb up a hill. Study 1 found that helpful actions are implicitly expected to be shared among members of the same group but not among members of different groups, but no such effect was found for harmful actions. This suggests that helpful actions are more likely than harmful actions to be implicitly generalized to group members. This finding was replicated in Study 2 by increasing the group size from three to five. Study 3 found that the null effect for generalizing harmful actions among group members is not due to the difficulty of detecting action generalization, as both helpful and harmful actions are similarly generalized within particular individuals. Moreover, Study 4 demonstrated that weakening social group information resulted in the absence of implicit generalization for helpful actions, suggesting the specificity of group membership. Study 5 revealed that the generalization of helping actions occurred when actions were performed by multiple group members rather than being repeated by one group member, showing group-based inductive generalization. Overall, these findings support valence-dependent implicit action generalization among group members. This implies that people may possess different knowledge regarding valenced actions on category-based generalization. 相似文献
