认知储备的测量及其在认知老化中的应用

认知储备是指个体自适应利用神经网络对不断增加的脑损伤进行补偿的能力, 它能显著影响个体的生理功能、认知功能和行为结果。当前有关认知储备的研究主要集中在认知储备的测量及其在认知老化研究中的应用方面。现有研究尽管已在认知储备的测量及其与认知老化的关系上取得越来越多的共识, 但在诸如认知储备测量的标准化、认知储备与认知衰退率、认知储备与脑病理的关系等问题上还存在较大争议。未来研究除应进一步标准化对认知储备的测量, 进而探讨认知储备的病理机制, 还应关注认知储备对老化的干预研究。

Pathways from Birth Weight to ADHD Symptoms through Fluid Reasoning in Youth with or without Intellectual Disability

Although individual differences in fluid reasoning reliably mediate predictions of attention-deficit/hyperactivity disorder (ADHD) symptoms from birth weight in youth with typical cognitive development (TD), it is unknown if this indirect effect operates similarly in the development of ADHD symptoms secondary to intellectual disability (ID). Thus, we evaluated mediation by fluid reasoning in a longitudinal sample of 163 youth (45% female) with (n = 52) or without (n = 111) ID who were followed prospectively from age 5 to age 13. At age 9, youth completed the Arithmetic subtest of the Wechsler Intelligence Scale for Children, a measure of fluid reasoning. At ages 9 and 13, mothers and teachers separately rated youth ADHD symptoms and mothers completed a diagnostic interview. Mediation was tested via path analysis with bootstrapped confidence intervals, and moderated mediation estimated whether indirect effects differed between ID and TD youth or based on youth IQ. Controlling for demographic factors and age 9 ADHD symptoms, age 9 Arithmetic mediated birth weight and multi-method/informant age 13 ADHD symptoms, such that birth weight positively predicted Arithmetic, which negatively predicted ADHD symptoms. Neither ID status nor IQ moderated the observed indirect effect through Arithmetic, suggesting that it was similar for ID and TD youth as well as across the range of youth IQs. These findings support previous evidence that fluid reasoning, as measured by Arithmetic, may causally mediate birth weight and ADHD symptoms, and suggest that this pathway operates similarly with respect to the development of ADHD symptoms in youth with ID.     

家庭社会经济地位与父母教养方式对儿童青少年公正世界信念的影响

以全国24013名10~15岁儿童青少年为对象,探讨家庭社会经济地位与父母教养方式对公正世界信念的影响。结果发现：（1）家庭社会经济地位能够正向预测一般公正世界信念与个人公正世界信念;（2）权威型教养方式能够正向预测一般公正世界信念与个人公正世界信念,独裁型与纵容型教养方式能够负向预测一般公正世界信念与个人公正世界信念;（3）家庭社会经济地位与父母教养方式的交互作用对公正世界信念的影响显著,其中,权威型教养方式对高家庭社会经济地位比对低家庭社会经济地位儿童青少年公正世界信念的促进作用更大,独裁型与纵容型教养方式对低家庭社会经济地位比对高家庭社会经济地位儿童青少年公正世界信念的削弱作用更大。     

Retraction and Research Integrity Education in China

This article draws the attention of research managers and policy makers to the issue that to become a science power curtailing misconduct is the daunting challenge that emerging countries simply cannot ignore. Systematic and orchestrated efforts are needed to foster and institutionalize research integrity education among all stakeholders.

     

拼音在中文学习中的作用及加工机制

拼音作为增强汉字形音转换的桥梁在中文学习和教学中被广泛应用。为深入了解拼音在中文学习中的作用及其加工机制,在系统梳理已有研究成果的基础上,分别从拼音学习对语音意识发展的影响,拼音的注音方式和呈现方式对汉字学习的影响,拼音加工的认知神经机制三个方面进行综述。研究结果表明,拼音学习可以促进语音意识的发展;不同的拼音注音方式和呈现方式会对汉字学习产生不同的影响;拼音加工的机制与汉字加工存在不同,但拼音加工的机制仍有待于进一步深入。     

手机分心对行人过街中信息加工及行为的影响

行人过街时, 因使用手机而造成的伤亡事故持续增长。过街时使用手机对行人信息加工、行为及安全均会产生影响。结果表明：使用手机的行人, 在场景知觉阶段注意范围更狭窄, 在外周视野的注意力明显下降; 过街决策阶段, 更容易错过过街机会或做出更有风险的决策; 运动控制阶段, 使用手机会改变行人步态, 降低其动作稳定性。以上效应还受到行人使用手机方式的调节, 但综合看来, 手机分心提升了行人过街风险, 更容易造成过街事故。最后, 通过建立手机分心对行人过街中信息加工及行为影响的概念模型, 指出未来研究应评估手机分心如何影响行人听觉信息的获取, 以及间隔接受决策的子过程, 从而为后期有针对性地干预提供理论基础。     

Evolving team cognition: The impact of team situation models on team effectiveness

The current research examined a moderated mediation model for the relationships among indicators of objective career success (salary and job level), subjective career success (career satisfaction), and turnover intention, as well as the boundary conditions of this process. Based on a survey study among a sample of Chinese managers (N = 324), we found that both salary and job level were negatively related to turnover intention, with these relations fully mediated by career satisfaction. The results further showed that the relation between job level and career satisfaction was weaker among managers who perceived a higher level of organizational career management, but stronger among managers with a higher managerial career anchor. In support of our hypothesized model, the indirect effect of job level on turnover intention through career satisfaction existed only among managers who perceived a lower level of organizational career management or managers with a higher managerial career anchor. These findings carry implications for research on career success and turnover intention.     

空间转换在记叙文阅读情境模型建构中的作用

采用探测词和事件分割范式探讨了空间转换与事件转换分离的情况下, 空间转换在记叙文情境模型建构中的作用。实验1a重复前人研究, 探讨空间转换对阅读时间和情境模型更新的影响, 并验证在空间转换对情境模型的影响的研究中, 采用多指标探测范式的合理性。实验1b探讨在空间转换与事件转换相分离的条件下, 空间转换对情境模型更新的影响; 实验2a探讨空间转换对事件分割的影响, 并验证在空间转换对情境模型的影响的研究中, 采用事件分割范式的合理性; 实验2b探讨空间转换与事件转换相分离的条件下, 空间转换对事件分割的影响, 从而验证空间转换对情境模型更新的影响。结果表明, 当空间转换与事件转换相分离时, 不引起情境模型的更新, 事件单元是建构记叙文心理表征的核心单元, 空间转换只有在标识事件转换的情况下, 才能引发读者更新情境模型。
