时间知觉的注意调节:一项ERP研究 总被引:1,自引:0,他引:1
采用双任务实验范式探讨时间知觉注意调节的动态过程。通过指导语使被试按照比例将注意分配到声音刺激的时间属性与音调属性上,形成对时间因素不同注意程度的五种注意条件,同时记录反应时、错误率和事件相关电位数据。对峰值分析发现,P2注意条件主效应不显著,但多重比较时T(只注意时间)与P(只注意音调)条件差异显著;对CNV平均波幅分析,发现注意条件主效应显著,随着分配在时间属性上的注意的减少,其波幅逐渐降低;对T与P条件的差异波地形图分析发现,波幅最大的区域位于额叶、中央区和顶叶;该差异波的偶极子定位于辅助运动区(额上回、额中回)和顶下小叶。以上结果表明,P2阶段存在时间信息加工;CNV反映时间知觉的注意调节,时间知觉中存在控制加工应该以CNV的出现为指标;辅助运动区可能为时间知觉的核心成分,具有跨通道效应;顶下小叶也与对时间的注意有关,但并不是特异性的。本研究不支持Lewis提出的 “自动”与“认知控制”计时系统理论中 “秒”为两系统分界点以及辅助运动区只属于“自动计时系统”的观点 相似文献

Although some studies have revealed that traditional filial piety belief is weakening, few have explored whether and how the role of the belief in social life has changed correspondingly. The present study used questionnaires to examine solutions to filial piety dilemmas and the roles of contextual theme, filial piety beliefs, and generation in a sample of 123 young and 92 middle‐aged Chinese adults. With respect to the solutions adopted to solve parent?child conflicts, preferences varied depending on the dilemma themes. Specifically, participants were more likely to select a self‐sacrifice (rather than an ego‐centered) solution for respect dilemmas than for caring dilemmas, and least likely to do so for obedience dilemmas. Participants were also likely to select a balancing (rather than an ego‐centered) solution for respect or caring dilemmas than for obedience dilemmas. In addition, the concordance between beliefs and solutions was exhibited in reciprocal, but not authoritarian, filial piety beliefs. Individuals with stronger reciprocal filial piety beliefs were more likely to select self‐sacrifice or balancing solutions than ego‐centered solutions whereas authoritarian filial piety showed no influence on solutions for either young or middle‐aged adults. Furthermore, the generation effect was not significant, and the solution selection did not differ between young and middle‐aged adults. 相似文献

我国约有一半的大学生经受着考试焦虑的困扰。结合国内外已有研究成果,本研究以624名大学生为被试,考察了自我决定动机的3种类型和拖延行为的2种类型对考试焦虑的忧虑性、情绪性的影响。结果发现:(1) 无动机对考试焦虑的2种类型都有正向的直接影响。(2) 唤起性拖延仅对情绪性有正向直接影响,而回避性拖延仅对忧虑性有正向直接影响。(3) 唤起性拖延在无动机影响考试焦虑的情绪性中起了重要的部分中介作用,而回避性拖延在无动机影响考试焦虑的忧虑性中起了重要的部分中介作用。 相似文献

采用重复启动范式探讨语义启动效应减少的机制。结果发现,在SOA为短的167ms条件下,重复/相同和重复/相关的启动效应无差异,且重复/相关启动并未导致语义启动效应的减少;而在SOA为长的1200ms条件下,重复/相同和重复/相关的启动效应差异显著,且重复/相关启动导致了语义启动效应的减少,而重复/相同未导致语义启动效应的减少。在抵消了期望和消退的作用后,在SOA为1200ms条件下所得到的重复/相同和重复/相关启动效应的差异,是由于扩散受到了阻碍而导致的。这一结论支持了激活扩散是有一定条件的观点。 相似文献

The cross-sectional study aimed to investigate the career adaptability and its associated factors among 431 student nurses. Participants completed questionnaires on demographics, career adaptability, adversity quotient, clinical learning environment and social support. Findings revealed that student nurses' adversity quotients, individualized clinical learning environment, and family social support associated positively with their degree of career adaptability, even after multiple adjustments. Additionally, career adaptability scores were higher among associate degree student nurses and those who had served as student leaders. These findings may provide referable evidence for schools and educators to improve student nurses' career adaptability. 相似文献

重症医学作为二级学科成立才10余年,与普通科室不同,重症医学科收治的患者都处于极其危重状态,需要在查房过程中迅速做出诊断、制定治疗决策并高效执行。重症医学临床查房应充分做好查房前准备,简洁汇报病史,运用核查表行结构化查房,组织好多学科查房,注重人文关怀。重症医学查房的临床思维包括:抓住主要矛盾、注重整体,诊断第一、治疗规范,运用连续“提问”和连续“假设”的证伪思维,动态地收集患者信息,不断巩固自己的诊断,或者及时修正自己的诊断和补充自己的诊断,从而让患者得到最优的治疗。

Research on career adaptability has found that it helps people adapt at work. However, in modern uncertain and dynamic work environment, people need to perform proactive work behaviour to ensure individual effectiveness. Thus, to understand how career adaptability advances career development, it is necessary to examine its influences on proactive work behaviour. Adopting a relational perceptive, the current paper proposed leader-member exchange and perceived coworker support as the mediators and future work self salience as a moderator. Data were collected with a three-wave design in China. Findings largely supported the propositions, albeit showing partial mediation effects. This study extends existing understandings of the role of career adaptability at work, provides a new perspective about why it influences work-related outcomes and enriches the knowledge about the antecedents of proactive work behaviour. 相似文献
