邻近效应对多媒体学习中图文整合的影响:线索的作用

在多媒体学习中图文排列的邻近或远离会影响学习的效果。本研究操纵了多媒体呈现的图文排列位置,采用颜色作为线索引导注意,探讨了线索有无和图片-文字的空间位置对多媒体学习图文整合的影响。结果发现:图文邻近呈现时的保持测验和迁移测验成绩好于图文远离呈现,图文邻近呈现时学习者对关键兴趣区的进出次数更多,体现出以文字为导向的阅读模式。线索并没有单独影响学习成绩和注意分配;但结合图文位置后,发现有线索时图文邻近学习材料的注视次数、进出关键兴趣区的次数显著多于图文远离。研究认为:图文的邻近效应不仅提高学习者对知识的识记和理解,同时也影响了学习者的注意分配过程,图文邻近呈现有助于图片和文本信息的注意联结和知识整合;线索能使邻近效应得到凸显,更好地促进图文信息的注视加工,但没有改进学习的效果。     

Chinese University Students’ Perceptions of Plagiarism

This study examines Chinese undergraduates’ perceptions of plagiarism in English academic writing in relation to their disciplinary background (i.e., hard vs. soft disciplines), academic enculturation (i.e., length of study in university), and gender. Drawing on data collected from 270 students at two universities in China, it finds clear discipline-based differences in participants’ knowledge of plagiarism and perceptions about its causes; an enculturational effect on perceived acceptability of and condemnatory attitudes toward plagiarism, with senior students being less harsh than their junior counterparts; and complex interactions among disciplinary background, length of study, and gender. Furthermore, it reveals conceptions of (il)legitimate intertextuality (i.e., textual borrowing) differing from those prevalent in Anglo American academia and clearly punitive stances on perceived plagiarism. These results suggest the need to take an educative rather than punitive approach to source use in English academic writing.     

熟练潮-普双言者的语义通达机制:来自通道比较的证据

采用跨语言启动的范畴判断范式,通过2个实验,考察了熟练潮-普双言者在听觉通道内和听-视跨通道条件下的语义通达机制。结果发现,无论是以潮州话词语为启动词,还是以普通话词语为启动词,当词对具有高语义相关时,启动词均对目标词产生了显著的跨语言启动效应;在听觉通道内,两种语言之间的启动量无差异,而在听-视跨通道条件下,L2对L1的启动量显著大于L1对L2的启动量。这些结果表明,熟练潮-普双言者共享语义(概念)表征,词汇表征既相互独立又互相联系,L1与L2的词汇均能直接通达语义表征,但其联系强度及其相互之间的词汇表征联系强度均存在通道差异性。整个研究结果支持Kroll等人的修正分级模型。     

Judgment of infant cry: The roles of acoustic characteristics and sociodemographic characteristics

Adult judgments of infant cry are determined by both acoustic properties of the cry and listener sociodemographic characteristics. The main purpose of this research was to investigate how these two sources shape adult judgments of infant cry. We systematically manipulated both the acoustic properties of infant cries and contrasted listener sociodemographic characteristics. Then, we asked participants to listen to several acoustic manipulations of infant cries and to judge the level of distress the infant was expressing and the level of distress participants felt when listening. Finally, as a contrasting condition, participants estimated the age of the crying infant. Using tree‐based models, we found that judgments of the level of distress the infant was expressing as well as the level of distress listeners felt are mainly accounted for by select acoustic properties of infant cry (proportion of sound/pause, fundamental frequency, and number of utterances), whereas age estimates of a crying infant are determined mainly by listener sociodemographic characteristics (gender and parental status). Implications for understanding infant cry and its effects as well as early caregiver‐infant interactions are discussed.     

医事法学人才培养模式20年之进展

经过近二十年的积累,我国医事法学的人才培养在很多方面取得了长足的进展。全国有50余所高校开设了该专业方向,实现了从专科生到研究生的宽跨度培养。培养既懂医又懂法,且能在相关机构从事与医疗卫生活动相关的立法、司法与执法工作的复合型人才成为各院校共同的培养目标。包括医学基础课、法学基础课和专业特色课在内的理论课与包括医学实习和法学实践在内的实践课构成了医事法学的课程体系。从事医事法学研究的文献逐年增多。一支专业的师资队伍正在形成。     

中学生成就动机与成功恐惧的研究

运用成就动机问卷与投射测验研究了454名中学生的成就动机与成功恐惧,结果表明,中学生的成就动机存在显著的学校类型差异,重点中学学生的成就动机显著强于普通中学学生。男生和女生均存在着成功恐惧,其恐惧主要与学业、人际关系、家庭和事业有关。被试在女主人公身上投射出更多的成功恐惧。中学生追求成功的动机与成功恐惧呈显著的负相关,而避免失败的动机与成功恐惧呈显著的正相关。     

经皮迷走神经刺激对抑制控制的调节机制

近年众多研究表明,经皮迷走神经刺激(tVNS)作为一种新型、非侵入式的神经调控技术对个体的抑制控制功能具有积极的调节作用。已有研究发现, tVNS对抑制控制的调节作用可能是通过调控蓝斑核-去甲肾上腺素系统(LC-NE)的活动和神经递质GABA的浓度来实现的。然而,目前对tVNS调控抑制控制的神经机制仍存在诸多尚未明确的问题。未来研究在进一步优化tVNS的刺激参数后,可以从tVNS对抑制控制能力受损群体的调控作用及机制、如何实现和增强tVNS长期积极效应等方面进行深入探索。     

父母冲突对青少年攻击行为的影响:一个有调节的中介模型

采用青少年攻击行为量表、青少年攻击信念量表、亲子关系量表和儿童感知父母冲突量表对506名青少年进行测查,结果表明：（1）父母冲突对青少年攻击信念和攻击行为均有显著的正向预测作用;（2）青少年攻击信念在父母冲突与攻击行为之间起着中介作用;（3）青少年攻击信念与攻击行为的关系（中介效应的后半段路径）受到亲子关系的调节,即父母冲突对青少年攻击行为的影响是有调节的中介效应。     

Bridging the Gap: How Supervisors’ Perceptions of Guanxi HRM Practices Influence Subordinates’ Work Engagement

This study aims to provide new insights into the relationship between supervisors' perceptions of guanxi human resource management (HRM) practices and their subordinates' work engagement. We used a three time‐lagged sample from 45 work groups and 205 employees in a state‐owned organisation (Study 1) and cross‐sectional data from 101 work groups and 413 employees in 101 different organisations (Study 2) to test our hypotheses. The results revealed that supervisors' perceptions of guanxi HRM practices were positively related to subordinates' perceptions of guanxi HRM practices, which, in turn, negatively affected subordinates' work engagement. This indirect effect was stronger when group power distance was low or when individual power distance orientation was low.
