Self-esteem and proactive personality as predictors of future work self and career adaptability: An examination of mediating and moderating processes

Basing on career construction theory and self-verification theory, current research examined the mediating and moderating models for the relations among self-esteem, proactive personality, career exploration, future work self and career adaptability. A two-wave survey study was conducted among Chinese university students (N = 305). The results showed that both self-esteem and proactive personality (measured at time 1) positively predicted future work self and career adaptability (measured at time 2), with these relationships mediated by career exploration (measured at time 1). In addition, the results further revealed that the positive effect of self-esteem on career exploration was stronger among students who had a higher level of proactive personality. In support of the hypothesized moderated mediation model, for individuals with a higher level of proactive personality, the indirect effects of self-esteem on future work self and career adaptability through career exploration were stronger. These findings carry implications for research on career construction theory and career counseling practices.     

The linear transformation model with frailties for the analysis of item response times

The item response times (RTs) collected from computerized testing represent an underutilized source of information about items and examinees. In addition to knowing the examinees’ responses to each item, we can investigate the amount of time examinees spend on each item. In this paper, we propose a semi‐parametric model for RTs, the linear transformation model with a latent speed covariate, which combines the flexibility of non‐parametric modelling and the brevity as well as interpretability of parametric modelling. In this new model, the RTs, after some non‐parametric monotone transformation, become a linear model with latent speed as covariate plus an error term. The distribution of the error term implicitly defines the relationship between the RT and examinees’ latent speeds; whereas the non‐parametric transformation is able to describe various shapes of RT distributions. The linear transformation model represents a rich family of models that includes the Cox proportional hazards model, the Box–Cox normal model, and many other models as special cases. This new model is embedded in a hierarchical framework so that both RTs and responses are modelled simultaneously. A two‐stage estimation method is proposed. In the first stage, the Markov chain Monte Carlo method is employed to estimate the parametric part of the model. In the second stage, an estimating equation method with a recursive algorithm is adopted to estimate the non‐parametric transformation. Applicability of the new model is demonstrated with a simulation study and a real data application. Finally, methods to evaluate the model fit are suggested.

"心寓于身"论的发展历程

关于心身关系的理论,有始于柏拉图成于笛卡尔的二元论,包括实体二元论和性质二元论;还有从巴门尼德到斯宾诺莎都主张的一元论,包括偏向肯定身体与行为的物理主义与行为主义以及偏向肯定心灵的观念论.以上观点都把心灵和身体分而论之,导致了很多问题.实体二元论难以解释:既然心物是不同实体,那么它们之间如何有交互作用?     

脑损伤语言认知障碍研究 ——认知神经心理学研究途径

20世纪90年代以来,从认知神经科学的角度揭示语言及其它认知的脑机制成为科学研究的前沿与热点。研究各种脑损伤导致的特异性语言障碍,为探索语言和其它认知的结构、加工,及大脑不同部位在语言和其它认知活动中的功能增添了一条新的途径。同时也对临床失语症的诊断与康复起了很多积极的作用。汉语在世界语言体系中具有其独特性,对汉语的语言障碍及其脑机制的研究将为完善人类语义知识理论、语言的表征与加工模型有重要贡献,也为发展汉语失语症针对性的康复方案提供理论和实践基础     

小学五年级儿童执行功能特点研究

本研究旨在通过对小学五年级儿童的执行功能进行测试和训练,探究小学五年级学生注意转换能力、记忆刷新能力和抑制优势反应能力三种执行功能的特点.研究表明小学五年级儿童执行功能中的这三种能力是相互独立的,且具有不平衡性和可发展性特点.结果表明 ,小学五年级学生的注意转换能力明显低于大学生,同时也比成人平均水平低;记忆刷新能力优于成人平均水平;而抑制优势反应能力已基本达到成人平均水平.     

网络游戏成瘾:沉浸的影响及其作用机制

本研究以491名男大学生为被试,考察了沉浸对网络游戏成瘾的影响、沉浸的前因变量和相关作用机制。结果发现:(1)网络游戏中的沉浸与网络游戏成瘾呈显著正相关,与控制、挑战呈显著正相关;挑战和控制与网络游戏成瘾呈显著正相关。(2)挑战通过沉浸的完全中介作用对网络游戏成瘾产生影响,挑战对网络游戏成瘾没有直接效应;控制除了通过沉浸的部分中介作用对网络游戏成瘾产生影响,还对网络游戏成瘾有直接效应。     

口语词语产生理论与语法特征通达研究的发展

近年来,研究者对口语词汇产生过程的各个层次展开了深入的探讨,各种理论与模型争论的焦点主要集中在各阶段间的关系、表征被选择的方式和词汇化的时间进程等方面,其中关于语法特征的通达一直是人们最为关注的问题之一。文章回顾了该领域内从研究初期至今较有代表性的一些理论、模型和有关语法特征通达的研究进展。希望能对有关汉语字词产生基本问题的研究有所推动。     

邵伟华不是邵雍二十九代孙

邵伟华声称自己是邵雍的"二十九代孙",并以此到处招摇撞骗。邵雍本是北宋著名思想家,但民间盛传邵雍是一位"打卦算命"有准的大师,还有几本属"邵康节撰"的算命书,如《铁板神数》、《梅花易数》等。于是邵伟华便跑到河南辉县,同一位叫邵理文的老农攀扯上了血缘关系.之后便到处宣扬自己是     

认知风格影响归类过程中的神经活动-来自fMRI研究的证据

行为学研究表明归类过程中的反应具有认知风格上的不同,但未有研究明确探讨归类过程的神经活动是否也受认知风格的影响。本研究通过双重认知风格分型任务筛选出分析型和整体型被试,以探讨归类过程中二者之间是否表现出神经活动的差异。实验任务要求被试从两个待选物中选出与目标物属于同一类别的一个。同时,采用fMRI技术扫描并记录他们完成任务时的BOLD信号。结果发现,与基线任务相比,整体型和分析型个体均激活了额-枕网络的一些脑区,包括额下回、楔前叶、枕中回等,表明不同认知风格个体在任务中可能共享与工作记忆等相关的脑区。另外,与分析型个体相比,整体型个体在右额下回、右旁海马回呈现更广泛的特异性激活,提示,认知风格可以影响归类过程中的脑活动,而整体型个体大脑右半球更强烈的活动表明这一类型认知风格个体在归类时更依赖于远距离的语义联结。
