On the predictive validity of various corpus-based frequency norms in L2 English lexical processing

The predictive validity of various corpus-based frequency norms in first-language lexical processing has been intensively investigated in previous research, but less attention has been paid to this issue in second-language (L2) processing. To bridge the gap, in the present study we took English as a case in point and compared the predictive power of a large set of corpus-based frequency norms for the performance of an L2 English visual lexical decision task (LDT). Our results showed that, in general, the frequency norms from SUBTLEX-US and WorldLex–Blog tended to predict L2 performance better in reaction times, whereas the frequency norms from corpora with a mixture of written and spoken genres (CELEX, WorldLex–Blog, BNC, ANC, and COCA) tended to predict L2 accuracy better. Although replicated in both low- and high-proficiency L2 English learners, these patterns were not exactly the same as those found in LDT data from native English speakers. In addition, we only observed some limited advantages of the lemma frequency and contextual diversity measures over the wordform frequency measure in predicting L2 lexical processing. The results of the present study, especially the detailed comparisons among the different corpora, provide methodological implications for future L2 lexical research.

When friends exchange negative feedback

In four studies, we document an increase in the amount of negative feedback friends and colleagues exchange as their relationship deepens. We find that both actual and perceived relationship depth increase the amount of negative feedback people seek from and provide to each other, as well as their tendency to invest in a focal (relationship or performance) goal in response to negative feedback. The amount of positive feedback on goal pursuit, by contrast, remains stable as the relationship deepens. We attribute the increase in negative feedback to the different meaning of such feedback for people in deep versus shallow relationships: only in the context of deep relationships does negative feedback signal insufficient resource investment in the focal goal, and hence close friends and colleagues seek, provide, and respond to negative feedback.     

评价中心结构效度的多元概化理论分析研究

评价中心技术是现代人事测评的一种主要形式,主要通过多种模拟任务来测评高级管理人才。然而,少有研究能证明它具有理想的结构效度。该研究运用多质多法分析了某金融企业一次真实的评价中心测评项目,发现测评的结构效度并不理想。接着,通过多元概化理论的分析,探讨了结构效度不理想的原因,并指出了评价中心任务与所测维度之间的关系,以及对各维度的测量信度。最后,根据分析结果,探讨了优化评价中心结构效度和提升整体测量信度的途径。     

汉语儿童英汉语语音意识和英语单词认读能力的关系

本研究考察了小学儿童语音意识和英语单词认读的关系。一系列相关和回归分析发现,英、汉语语音意识与英语单词认读有密切关系,但这种关系随年级变化而变化,英语语音意识对汉语儿童英语单词认读并不具有稳定的预测力;而且并不总是最有预测力的因素。结果说明,与英语本族语儿童相比,语音意识在汉语儿童的英语单词认读学习中起了不同的作用。     

手机冷落行为的前因、后果与作用机制

手机冷落行为是指个体在社交场合只顾低头玩手机, 而无暇顾及(冷落)身边人或事物的行为, 是移动互联网时代的一种普遍社会现象。通过对相关研究进行梳理, 对手机冷落行为的前因、后果与作用机制进行了系统的归纳总结, 并提出未来研究需要进一步采用以人为中心的方法探讨手机冷落行为的发生机制, 从边界创建视角考察手机冷落行为的影响因素, 揭示手机冷落行为与人际关系质量的双向影响, 明晰手机冷落行为对行为发出者的影响以及基于非人际感知视角探讨手机冷落行为的作用机理。     

关于动力系统中自我强化和学生期待对学习效率影响的实验研究

本实验考察了在教学活动中,动力系统中自我强化和学生期待两因素与中学生学习效率的关系。结果表明：在其它教学条件相同的情况下,适当地、适时地满足学生期待对初中生学习效率的提高有较明显的作用,而对高中学生则作用不明显;对中学生进行自我强化的训练,有助于高中生学习效率的提高,而对初中生学习效率的作用则不明显;实验中未出现交互作用。     

阿兰·奈斯论深层生态学

奈斯看来,深层生态学既是一种社会思潮,又是以这种思潮为指导的一场旨在改变现行的人类实践模式的社会运动。作为一种社会思潮,它是一个由一系列基本原理构成的演绎性的逻辑体系。奈斯认为,深层生态学的理论内核是八大原理,而在其背后,还有更为基本的前提与终极规范,即各种生态智慧。而奈斯本人的生态智慧的终极规范是(大)自我实现。
