采用启动条件下的词汇判断任务,考察熟练手语使用者和无手语经验成年听人的跨模态语义启动效应。结果发现:1)在象似词条件下,两组被试判断汉语语义相关词的反应时均快于语义无关词,说明手语象似词和汉语词之间存在跨模态语义启动效应。2)在非象似词条件下,仅手语熟练被试判断汉语语义相关词的反应时快于语义无关词,无手语经验被试判断汉语语义相关词和无关词的速度没有差异。这是由于前者心理词库中的手语词和口语词共享语义表征,而后者主要依赖手语象似词的视觉模拟性。整个研究表明,中国手语和汉语间存在跨模态语义启动效应,但该效应受到手语词象似性和手语学习经历的调节。 相似文献

书写是小学阶段书面语发展的重要目标之一,受到多种认知技能的影响。采用追踪研究考察了127名小学五年级儿童的语素意识和快速命名对其五、六年级时的汉字听写和抄写的影响。控制了非言语智力、语音意识后,结果发现:(1)儿童汉字听写和抄写能力随时间发展均有显著增长;(2)五年级语素意识显著预测了五、六年级两个时间点的听写,五年级快速命名仅显著预测了五年级听写;(3)五年级语素意识和快速命名预测了五年级抄写。研究表明语素意识和快速命名对汉字听写和抄写存在不同的影响作用。 相似文献

AbstractIn this research, we hypothesized that employees’ belief in a just world (BJW) would be positively related to their voice behavior, i.e., the expression of ideas or opinions with the intention of engendering organizational improvement or change, and that this relation would be mediated by perceived voice efficacy and perceived voice risk. To test these hypotheses, we collected self-reported data from employees in two different countries: China (N?=?313) and Germany (N?=?190). The results revealed a positive association between BJW and employee voice behavior in both samples. The two-mediator model was confirmed in the Chinese sample, while only perceived voice efficacy played a mediating role in the German sample. Possible reasons for these differences may be related to differences in cultural dimensions and education levels between the samples. The findings emphasize the importance of bolstering employees’ belief in justice and the organizational climate, which influence perceived voice efficacy and risk, as means to increase organizational voice behavior. 相似文献

Drawing on a sample of 438 working professionals from various organizations across the central United States, the authors investigated the relationship between Holland's (1959, 1997) RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) model and employee perceptions of work-family conflict. Results revealed that the RIASEC model contributed unique variance in predicting work-family conflict beyond demographic characteristics and the Big Five personality constructs. The RIASEC interests were found to be associated with different dimensions of work-family conflict. These results signal that vocational interests may influence not only work-related attitudes and behaviors (e.g., job satisfaction, performance), but also one's ability to balance work and family demands. 相似文献

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study
Jifu Wang Lin Yu Mengyang He Changzhu Qi 《Advances in cognitive psychology / University of Finance and Management in Warsaw》2020,16(4):353
The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources. 相似文献
