Based on career construction theory, the current research examined whether career adaptability mediates the relations of the personality traits (Five-Factor Model personality traits and behavioral inhibition and activation systems (BIS/BAS)) to career exploration behavior. Results from a survey in Chinese university students (N = 264) showed that career exploration correlated negatively with neuroticism, and positively with openness to experience, extroversion, agreeableness, conscientiousness and BAS. Results of regression analyses further showed that openness to experience, agreeableness, conscientiousness and BAS served as the strongest predictors for career exploration. In addition, career adaptability was shown to be a key mediator for the relationships between personality traits and career exploration behavior. Career concern and career curiosity were the more important dimensions in the mediation model. These findings advance current understandings on how different personality traits predict career exploration behavior.  相似文献

This study investigated the influence of social comparison on career choice certainty and its potential mechanisms: regret as a mediator and vocational identity as a moderator. Before the formal experiment, 30 pairs of vocational values representing typical conflicts in career decision-making for Chinese university students were obtained. The formal experiment adopted a single-factor (social comparison VS no comparison) between-subject design with vocational identity as an independent covariate. Ninety-eight junior and senior undergraduate students and graduate students in a university in China were invited to participate in the computer-controlled experiment, which involved vocational identity assessment, social comparison manipulation, and analogue career-choice scenario tests. Path analysis showed that: (a) Social comparison significantly and negatively predicted career choice certainty; (b) Regret partially mediated the effect of social comparison on career choice certainty; and (c) Vocational identity did not moderate the path between social comparison and regret, but significantly moderated the negative effect of regret on career choice certainty. These results indicated that in the collectivistic Chinese culture, individuals' career development trajectories may not be totally independent and are subject to influences by other people's choices, while emotion of regret and vocational identity development all play significant roles in this intricate process.  相似文献

The temperature-dependent elastic constants of body-centred cubic (bcc) phase W are presented from first principles quasi-static approach. With the quasi-harmonic approximation model, the Hugoniot equation of state and temperature-dependence linear thermal expansion coefficient is successfully obtained. The adiabatic elastic constants show a normal behaviour with temperature: decrease with increasing temperature. Based on the obtained adiabatic elastic constants, the structural stability and polycrystalline aggregate properties including bulk modulus B, shear modulus G, and B/G ratio are analysed for bcc phase W. In addition, the sound velocities as a function of temperature for bcc phase W are predicted.  相似文献

具身-生成取向正在引领当代认知科学加速发展,然而学术界在理解“具身-生成”的内涵上却正陷入“战国时代”,这严重影响了该取向的理论效力.通过分析来自交叉学科的相关证据,发现“具身”与“生成”既有联系,又有区别,两者相互支撑.具身认知主要考察嵌入在社会情境中的身体结构、活动、内容与形式对认知活动的影响.“生成”强调认知结构在大脑、身体与环境的结构性耦合中涌现出来的动态机制,尤其是知觉-行动环路的作用.未来,具身-生成的认知科学只有在应对来自经典认知科学的挑战过程中才有可能走出“战国时代”.  相似文献

基于模拟研究比较了K-means方法、潜在类别模型和混合Rasch模型在二分外显变量情境下的聚类效果.结果表明:(1)潜在类别数量、变量数量、样本量、样本平衡和变量间相关对K-means方法、潜在类别模型和混合Rasch模型的分类准确性均有影响且因素间的交互作用存在;(2)除了在2个潜在类别的样本不平衡条件下K-means方法表现较差外,在其他条件下与潜在类别模型和混合Rasch模型的表现相当;(3)混合Rasch模型的分类一致性在2个潜在类别的情境下要好于潜在类别模型,但是在4个潜在类别的情境下要差于潜在类别模型.  相似文献

Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (IB). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through IB. The semantically congruent Chinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that Chinese characters had more power to attract attention to escape sustained IB than pictures involved in visual processing. Presumably the finding of Chinese characters breaking through IB more easily might be due to the fact that Chinese characters look more distinct from pictures, rather than Chinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and Chinese characters in sustained IB.  相似文献

情绪效价和情绪唤醒是描述情绪的两个维度。情绪增强记忆效应表明情绪唤醒事件的记忆往往优于非情绪唤醒事件的记忆,但关于积极情绪记忆和消极情绪记忆哪个在记忆中处于优势仍存在争论。实验以情绪词对和中性词对为实验材料。实验一探讨积极情绪词语或消极情绪词语的记忆优势; 实验二探讨积极情绪环境或消极情绪环境中中性词语的记忆优势。在两种实验条件下,积极情绪下的自由回忆都优于消极情绪下的自由回忆; 多项加工树的存储—提取模型使用实验自由回忆和线索回忆的结果将记忆的存储和提取优势分离开来,结果表明:积极情绪事件记忆优势发生在存储阶段,而积极情绪环境记忆优势发生在存储和提取阶段; 积极情绪事件记忆偏向支持“刺激后编码增强假设”,积极情绪环境记忆偏向支持“唤醒—偏向竞争假设”。  相似文献

本文分别以90名和70名大学生为被试,通过问卷调查和实验任务的方式,探究童年环境、当前环境压力、时间感知和跨期选择四者之间的关系。结果表明:(1)童年环境影响时间感知,相比童年社会经济地位高的个体,童年社会经济地位低的个体更倾向于高估时距。(2)在正常环境下,个体时间感知完全中介作用于童年环境和跨期选择之间的关系,童年环境通过影响个体时间感知进而影响个体的跨期选择。(3)在当前环境压力下,时间感知并未起到中介作用。研究表明,时间感知在童年压力与在当前环境压力条件下,对跨期选择的影响作用不同。  相似文献
