儿童网络行为与学业成绩的关系:自我控制的调节效应

以547名4-6年级学生为研究对象,采用网络行为调查问卷、家庭富裕量表和青少年自我控制双系统量表,探讨儿童网络行为与学业成绩之间的关系,以及自我控制在二者之间的调节作用。结果发现:(1)儿童网络信息获取行为能够正向预测语文成绩;(2)自我控制调节网络信息获取行为与语文成绩之间的关系,同时也在儿童网络社交行为与语文成绩之间起调节作用。具体而言,自我控制中延迟满足的能力能够增强网络信息获取对语文成绩的促进作用,并且减缓网络社交行为对儿童的语文成绩的消极影响。

Purple sweet potato color repairs d-galactose-induced spatial learning and memory impairment by regulating the expression of synaptic proteins

Purple sweet potato color (PSPC), a class of naturally occurring anthocyanins used to color food (E163), has been reported to possess a variety of biological activities, including anti-oxidant, anti-tumor, and anti-inflammatory. The effect of PSPC on the spatial learning and memory of mice treated with d-galactose (d-gal) was evaluated by the Morris water maze; d-gal-treated mice had decreased performance compared with mice in the vehicle and PSPC groups, while the PSPC + d-gal group showed significantly shortened escape latency to platform, increased swimming speed, more target quadrant search time and more platform crossings as compared with the d-gal group. Brain functions, such as memory formation and recovery of function after injury, depend on proper regulation of the expression levels of the pre- and post-synaptic proteins. We investigated the expression of four pre-synaptic proteins (growth-associated protein-43, synapsin-I, synaptophysin, and synaptotagmin) and two post-synaptic proteins (post-synaptic density protein-95 and Ca²⁺/calmodulin-dependent protein kinase II) in the hippocampus and cerebral cortex, respectively, in response to different treatments. Western blotting analysis showed that there were significant decreases in the expression of these representative synaptic proteins in the hippocampus and cerebral cortex of d-gal-treated mice. Interestingly, these decreased expression levels of synaptic proteins could be reversed by PSPC. The levels of expression of these representative synaptic proteins in mice treated with PSPC alone were not significantly different from those in untreated mice. The results of this study suggested that memory impairment and synaptic protein loss in d-gal-treated mice may be improved by treatment with PSPC.     

联想－命题评价模型——态度改变的新解释

态度是社会心理学研究的重要领域,内隐和外显态度之间的区别和联系是近年来态度研究的重要主题。Gawronski和Bodenhausen提出的APE（Associative-propositionalEvaluation）模型认为,内隐和外显态度有各自不同的潜在心理过程：内隐态度基于联想加工,外显态度则基于命题加工。APE模型指出,正是由于联想和命题加工的相互作用导致了内隐和外显态度改变的几种具体模式。文章介绍了模型的理论基础和主要内容,并对此模型进行评价和讨论     

老年人生命态度及其与抑郁和社会支持的关系

使用死亡态度描绘量表(修订版)、流调中心用抑郁量表和个人资源量表2000对京津地区的516位老年人进行问卷调查,探讨老年人生命态度的结构及特点,并选取几个因素探讨其对老年人生命态度的影响。结果表明:(1)生命态度的结构包含死亡恐惧、死亡逃避、自然接受、趋近接受和逃离接受五个维度。(2)在生命态度的五个维度中,自然接受和趋近接受存在显著的性别差异,死亡恐惧、自然接受和逃离接受存在显著的教育程度差异;(3)抑郁与自然接受呈显著负相关,与生命态度其他四个维度呈显著正相关;社会支持与死亡恐惧呈显著负相关,与自然接受呈显著正相关。

Expectations and beyond: The nexus of AI instrumentality and brand credibility in voice assistant retention using extended expectation-confirmation model

AI-based voice assistants (AIVA) are capable of interpreting human speech and responding with useful information, aiding with tasks, and controlling other devices. The usage of these AIVAs has grown significantly worldwide. Despite this growth, studies on user behavior related to continued usage intention of AIVAs and effects on the long-term commercial sustainability of brands, remain low. What is less understood is the potential of AI instrumentality attributes and brand credibility components in provoking shifts in post-use behavior of AIVAs. This study proposes a model which expands on the Expectation-Confirmation Model for user continuance behavior of AIVAs, by integrating user's technology related traits, AI instrumentality attributes and brand credibility. To verify the research hypotheses, the study employed partial least square—structural equation modelling, based on 281 validated responses of a survey. This study highlights the significance of Optimism, Innovativeness, and Discomfort for post-adoption confirmation. Higher post-adoption confirmation is strongly associated with perceived intelligence, anthropomorphism, information quality, and system quality. Anthropomorphism and information quality are key factors for brand expertise, while anthropomorphism and system quality are significant for brand trustworthiness. The study confirms that brand expertise and trustworthiness lead to post-use satisfaction and use continuance intention. Understanding the antecedents of satisfaction and continuance intention extends the existing literature on AIVAs and provides valuable insights for academics and practitioners alike. Some implications for researchers and managers are discussed.     

左侧背外侧前额叶在程序性运动学习中的作用

程序性运动学习包括序列学习和随机学习。神经影像学研究表明背外侧前额叶皮层(DLPFC)和初级运动皮层(M1)在程序性运动学习中发挥重要作用, 但DLPFC和M1之间的联通性及其与不同程序性运动学习的关系尚不明确。本研究采用连续反应时间任务, 结合经颅磁刺激(TMS)方法, 探讨左侧DLPFC到M1的联通性在不同程序性运动学习中的差异。实验1采用两连发TMS探测DLPFC到M1的最佳投射时间点; 实验2, 被试分为2组, 分别进行序列学习和随机学习, 在学习前、后采集行为学数据, 以及M1的运动诱发电位和DLPFC-M1联通性的电生理学数据。行为学结果发现序列学习组的学习效果更佳; 电生理学结果发现, 两组被试学习前、后M1的运动诱发电位均未发生改变; 在最佳时间投射点、适当刺激强度下, 序列学习组DLPFC-M1联通性发生改变, 且与学习成绩相关, 而随机学习组没有改变。结果说明DLPFC到M1的联通性增强可能是序列学习成绩更佳的重要原因, 这一结果从电生理角度为DLPFC在运动学习中的作用提供了重要证据。
