语言产生中词频效应老化的神经基础与时间进程

词频效应指语言产生中人们对高频词汇的加工比低频词汇更快更准确的一种现象,它可能发生在语言产生中的不同阶段。对青年人和老年人词频效应的不同特点和加工机制进行比较,可以考察语言产生的认知老化机制。通过语言产生理论可对词频效应的老化进行预测,提出词频效应在个体发展和老化阶段的相对稳定性,分析老化导致词频效应相关的神经基础和加工时间进程的改变。未来研究可进一步分离词频效应与习得年龄效应对语言产生老化的影响,并扩展至神经退行性疾病患者中。     

儿童学校适应的分类及判定

以6579名小学三、五年级学生为被试,采用聚类分析和判别分析方法,结果表明:(1)根据儿童学校适应的指标将儿童的学校适应状况分为良好型、闲适型、紧张型、高危型四种类型.(2)良好型的儿童,在学业自我评估、学业动机和心理健康水平三个水平上的得分为正向,在问题行为上的得分为负;高危型儿童的结果与适应良好型的儿童完全相反;而在闲适型的儿童中,学业动机为负、心理健康水平为正;在紧张型的儿童中,学业动机为正向、而心理健康水平是负向的.(3)建立儿童学校适应的判别函数,为儿童在教育和心理问题进行指导提供了初步诊断依据,同时也对有关学校适应的研究提供新的视角.     

大学生学习适应量表的编制

对当代大学生学习适应问题进行了深入分析,在有关研究的基础上,探讨了当代大学生学习适应的主要因素,并编制一套适合当代大学生学习适应的测验。对四类院校918名大学生进行了施测,对调查数据进行了探索性因素分析和验证性因素分析。探索性因素分析结果表明,大学生学习适应的主要因素包括学习动机、教学模式、学习能力、学习态度、环境因素等5个方面;验证性因素分析结果表明,所提取的5个因素与构想模型拟合较好,测验具有较好的信、效度     

情绪智力的基础：情绪觉察的研究现状与展望

情绪觉察作为情绪智力的重要基础,指的是识别与描述自己和他人情绪的能力,对个体的心理健康,人际交往具有重要意义。为系统考察情绪觉察的研究现状,采用定性和定量相结合的方式回顾以往研究,即先采用文献计量学的方法定量分析该领域研究的概况,然后在此基础上,对研究的具体内容从概念界定、测量工具、神经基础、相关因素和干预研究五个方面作进一步系统梳理。最后,对以往研究进行了总结和展望,以期为今后研究提供借鉴。     

A cautionary note on using internal cross validation to select the number of clusters

A highly popular method for examining the stability of a data clustering is to split the data into two parts, cluster the observations in Part A, assign the objects in Part B to their nearest centroid in Part A, and then independently cluster the Part B objects. One then examines how close the two partitions are (say, by the Rand measure). Another proposal is to split the data into k parts, and see how their centroids cluster. By means of synthetic data analyses, we demonstrate that these approaches fail to identify the appropriate number of clusters, particularly as sample size becomes large and the variables exhibit higher correlations.The authors express their thanks to the Sol C. Snider Entrepreneurial Center, Wharton School, for support of this project.     

The impact of L1 structural frequency and cognate status on the timing of L2 production

The present study investigates the impact of first language (L1) structural frequency and L1 lexical accessibility, manipulated via cognate status, on second language (L2) speech production. L1 German–L2 English speakers and L1 English speakers completed a production task containing pre- and post-modified possessive noun phrase (NP) constructions (e.g. The actress’s sofa vs. The sofa of the actress) in which the head nouns were English-German cognates (e.g. sofa) or noncognates. While English prefers pre-modified NPs, German has a strong frequency bias for post-modified NPs. L2 English speakers exhibited higher production accuracy than L1 English speakers on post-modified NP sentences. However, facilitative L1 effects in production latencies were restricted to post-modified NP sentences containing cognates and only developed cumulatively after repeated exposure to post-modified NP sentences. We discuss how cognate status and L1 structural frequency differentially influence the accuracy and timing of choosing between different structural alternatives during L2 production.     

Sensitive Topics,Missing Data,and Refusal in Social Network Studies: An Ethical Examination

We describe our ethics‐driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis‐sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would‐be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP ) values. We outline literature that was helpful in thinking through this challenge; we looked outside of CP to the decolonization literature on refusal. Lessons learned include listening for the possible meanings of refusals and considering the level of engagement and the labor required of participants when designing research studies.     

心理理论和语言发展的关系

大量的研究表明心理理论和语言之间存在着密切的关系,但具体关系如何,一直存在争议。文章介绍了心理理论和语言关系的新近研究,着重阐述了目前关于二者关系的两种观点： （1）心理理论和语言发展之间不仅是早期揭示的一般相关关系,而是可能存在着因果关系——或以语言为因,或以心理理论为因;（2）心理理论和语言都受第三种因素影响,如执行功能和生长环境,但这些因素是究竟如何影响心理理论和语言发展的,还需深入探讨。文章最后对该领域今后的研究提出了新的见解和思路,包括对不同语言能力间的比较研究,对二者关系的跨文化研究和毕生取向研究等     

语言理解中情绪的动态模拟

采用混合实验设计, 句子-图片匹配范式和动态过程再现范式, 以包含静态情绪和动态变化情绪信息的句子为实验材料, 以被试对图片的反应时间为因变量指标, 通过不同时间间隔的设置以及不同的实验程序, 探讨了语言理解中静态情绪和动态情绪的心理模拟及其时间进程。结果表明：(1)被试对情绪的心理模拟与句中的语言描述一致, 情绪语境能够激活被试的经验模拟。(2)被试在句子理解加工的初期就能迅速、即时地模拟静态情绪信息, 且这种模拟具有一定的稳定性和持久性。(3)被试可以对动态变化的情绪进行动态的心理模拟, 不过这种模拟所需的时间要长, 是在句子理解加工的后期完成的。被试对不同情绪变化方向的句子模拟受到原情绪状态的影响, 当阅读由消极情绪向积极情绪变化的句子时, 由于被试固着于原来的消极情绪而发生了模拟积极情绪的困难。
