采用父母心理控制问卷、孤独感问卷、意志控制问卷和抑郁问卷对688名中学生(平均年龄15.62岁,男生314人)进行调查,考察了心理控制对青少年抑郁的影响、孤独感的中介作用以及意志控制的调节作用。结果发现:(1)在控制了年龄和性别之后,父母心理控制能正向预测青少年的抑郁;(2)孤独感在父母心理控制和青少年抑郁关系中起部分中介作用;(3)孤独感的中介作用受到意志控制的调节。因此,父母心理控制与青少年抑郁之间既存在中介效应又存在调节效应。 相似文献

体感交互是新兴的人机交互方式;当前,相关的人因学研究相对缺乏。本研究采用典型任务结合主观评价法,首次探索了用户运动信息反馈形式对体感交互用户体验的影响。笔者从易学性、控制性、情感与心理负荷四个方面,比较了有、无人形反馈形式对游戏体感菜单操作可用性的影响。结果发现,二者在心理负荷上无差异,无人形反馈在易学性上优于有人形,但有人形反馈在控制感上优于无人形,且更受用户喜爱。基于该结果,笔者建议在体感操作界面上使用有人形反馈。 相似文献

"循环并不可恶"。本文在此基础上讨论基础公理和反基础公理。首先指出基础公理原本就是一条有争议的公理;第二,说明基础公理的局限性;第三,详细论述反基础公理家族中的三个成员,并给出它们两两不相容的一个证明;第四,分析反基础公理导致集合论域在V=WF上不断扩张的方法,并指出这种扩张的方法与数系扩张的方法相同;最后结论:良基集合理论(ZFC)与非良基集合理论(ZFC~-+AFA(或者ZFC和ZFC~-+FAFA或者ZFC和ZFC~-+SAFA))之间的关系类似于欧几里得几何学与非欧几何学之间的关系。 相似文献

ABSTRACTThe tensile properties of TiNi43.5Fe6.5 alloy samples having different grain sizes (0.16, 0.35, 1.7, 2.3, and 3.9?μm) and fabricated by severe plastic deformation and annealing were investigated. It was observed that both the strength and the elongation of the alloy increase with a decrease in the grain size until the average size reaches 1.7?μm. However, for average grain sizes smaller than 1.7?μm, the elongation decreases continuously with further grain refinement. On the other hand, the strain-hardening rate does not decrease with the decrease in plasticity but instead increases slightly. The poor ductility of the ultrafine-grained TiNi43.5Fe6.5 alloy is accompanied by a high degree of strain hardening. This newly observed ductility behaviour of the ultrafine-grained TiNi43.5Fe6.5 alloy is elucidated by characterising the intragranular and grain boundaries. 相似文献

In daily life, visual working memory (VWM) typically works in contexts in which people make frequent saccades. Here, we investigated
whether people can effectively control the allocation of VWM when making a saccade. Subjects were required to make an intervening
saccade in the process of a memory task. The saccade target was either a to-be-remembered item or an extra, not-to-be-remembered
item. The results showed that memory performance was poorer when a saccade was made to the extra, not-to-be-remembered item,
regardless of its similarity to the memory item(s). In contrast, when memorizing the items while remaining fixated, subjects
had similar memory performance whether an extra, not-to-be-remembered item was present or not. Taken together, these results
demonstrated that volitional control over VWM allocation is greatly impaired when a saccade is made, indicating that VWM contains
an automatic part that cooperates with eye movements and is allocated to a saccade target obligatorily. 相似文献

安乐死问题一直都是一个争议性话题。从学理上,安乐死可以分为自愿安乐死和无意愿安乐死。自由主义的伦理学分为义务论和功利主义。以自由主义哲学观来审视两类安乐死合法化问题:自愿安乐死体现病人自由意志的选择,是人格尊严之自主性的结果;无意愿安乐死是由利益相关人代为选择,符合社会利益的最大化。通过严格立法来规范安乐死行为,也应成为我国法律的理性选择。 相似文献

A Pd81Si19 bulk metallic glassy rod with a diameter of 4.5 mm was produced by water quenching the fluxed alloy. Despite a negative heat of mixing between Pd and Si elements and very simple components constituting the binary Pd–Si glass-forming system, structural heterogeneity was induced either by slow cooling of a liquid or sub-Tg annealing of glassy ribbons. The sub-Tg annealing experiments evidenced that a more ordered amorphous phase emerged from the original glassy matrix. Our work provides an alternative way to tune the microstructure of metallic glasses by subsequent thermal treatment on an as-prepared single glassy phase. 相似文献
