Prospective memory training in young adults enhances trained-task but not transfer-task performance

ABSTRACT

Training and transfer effects of prospective memory training have not been assessed in healthy young adults yet. The present study examined the effects of an 8-day prospective memory training programme using the Virtual Week computer game in 18–24-year-old students. Using the performance of an active control group as comparison, the study revealed a significant short-lived beneficial training-induced effect on a nearest-transfer task consisting of a different version of the trained task. No evidence was obtained for transfer effects to other tasks measuring prospective memory (near transfer), or to tasks measuring various executive functions or general intelligence (far transfer). These results were compared to those from a previous study in which an identical training and testing protocol was used in 13–15-year-old adolescents. This study did reveal some evidence of near and far transfer. The results of the two studies combined suggest a greater potential for prospective memory training to induce beneficial transfer effects in young adolescents than in young adults.     

Are personality disorders associated with social welfare burden in the United States?

This study examined the association between personality disorders and use of major social welfare services in a nationally representative sample of U.S. adults (N = 43,093). Social welfare services received and diagnoses of personality, substance use, mood, and anxiety disorders were assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV-version. Analyses quantified the association between personality disorders and forms of public assistance while controlling for numerous confounds. Logistic regression analyses revealed dependent personality disorder, paranoid personality disorder, antisocial personality disorder, and avoidant personality disorder were significantly associated with increased odds of receiving public assistance. In contrast, persons diagnosed with histrionic, schizoid, and obsessive-personality disorder were not significantly more likely to receive any public welfare service. Development of effective prevention and treatment of personality disorders would likely lead to reductions in overall social welfare burden.     

Gender differences in the effects of post-learning emotion on consolidation of item memory and source memory

Item memory and source memory are two integral elements of episodic memory. Although many studies have examined the effect of emotion on item memory, little research has simultaneously taken into account item memory and source memory. In addition, in the majority of previous studies, learning stimuli are used as the source of emotion, making it difficult to understand whether emotion has an effect on encoding or on consolidation of episodic memory. Furthermore, although gender differences exist in neurophysiological responses to emotional stimuli, in many studies gender differences were neglected and this leaves the picture incomplete regarding the effect of emotion on episodic memory. In this study, we examined gender differences in the effects of post-learning emotion on consolidation of item memory and source memory. Participants learned neutral Chinese nouns, took a memory pretest, and were then randomly assigned to three conditions, in which they either watched a 3-min negative video clip, or watched a 3-min positive video clip, or remained calm and relaxed for 3 min. Thirty minutes after the initial learning, participants took a memory posttest. We found that: (1) For females, post-learning negative emotion enhanced consolidation of item memory; however, neither negative emotion nor positive emotion had a significant effect on consolidation of source memory; (2) For males, neither negative nor positive emotion after learning had a significant effect on either item memory or source memory. Possible reasons for the gender differences, as well as the theoretical significance and practical implications of this study were discussed.     

双特征空间客体捆绑关系的存储机制——来自ERP的证据

利用事件相关电位技术(ERPs),采用延迟匹配任务的实验范式,测查了16名正常被试完成位置客体、方向客体和位置—方向捆绑客体的工作记忆诱发的皮层慢电位。实验发现:在第1个客体呈现后的300ms到600ms之间,在顶叶皮层(CP5、P7、P3),位置客体、方向客体比捆绑客体诱发了一个更负的成分; 在右额(F4、FC6、FC2、F8)、右后颞(TP10)、左颞(T7)、左后颞(TP9)等脑区,捆绑客体比单一特征客体诱发出了一个更正的成分; 在800至1400ms的慢波成分上,位置和方向捆绑客体在F4、FC6和F8三个记录点诱发的波形比单一特征客体的波形波幅更正。右侧前额叶参与了客体整合表征的存储,该结果支持了情景缓冲器的假设。     

领导幽默的影响效果及其理论解释

领导幽默(leader humor), 作为一种有效的管理工具和手段, 近年来受到了理论界和实务界的广泛关注。在回顾领导幽默概念的基础上, 深入探究了领导幽默的影响效果及其作用机制, 总结发现领导幽默相关研究主要围绕七种视角展开, 分别是关系过程视角、社会交换理论、社会信息加工理论、关系认同视角、积极情绪视角、压力释放视角以及领导风格类型视角。未来研究应基于互动和结构的视角探讨领导幽默的影响效果以及基于社会信息加工理论关注领导幽默的作用机制。     

浅论《性命圭旨》中的性命观

"性命"是中国传统哲学的一对基本范畴,是儒、释、道、三家都关注的重要问题,但各家对其的理解和解释却不尽相同.<性命主旨>通过三教合通来阐释道教内丹学,融合中国传统文化中儒、释、道三家性命学的精髓,力倡性命双修,坚持性功、命功并重亦即精、气、神兼炼的原则,反对孤修一物.道教内丹是从后天的神气入手,其目的是修先天的元神、元气,最后神气合炼,提炼出元神.正是在这层意义上,该书尤其重视修心,并认为儒、释、道三家得以融合的核心就是"心性".     

家庭环境、专业满意度与大一新生心理健康的关系

为探究家庭环境和专业满意度对大一新生心理健康水平的影响。通过南京大学2013级3191名大一学生UPI问卷调查,采用回归方程分析家庭环境中的家庭来源地、家庭经济、是否独生子女、家庭环境认知以及专业满意度对大一新生心理健康的影响作用。结果发现,家庭环境因素和专业满意度均显著影响大一新生的心理健康水平。     

不同年级学生词边界划分的发展研究

汉语书写系统中不存在明显的词边界,中文读者对于词的划分存在较大的差异。词意识和词性均是影响这一差异的因素,本研究从发展的角度来探讨这两个因素是如何作用于词边界划分的。实验分别选取三年级、五年级、八年级及高二年级学生完成词切分任务。结果发现:(1)词切分认同率随年级的升高而降低,切分出来的词单元逐渐增大;(2)词切分认同率随年级变化的趋势会因词性的不同而发生变化,助词、形容词前、连词和介词后的切分认同率与总体趋势保持一致,但形容词前、数词、量词和介词前的切分认同率并未随年级的变化而变化。结果表明,词意识对中文读者词切分的影响受到词性的调节。     

When Do Employees Speak up for Their Customers? A Model of Voice in a Customer Service Context

We develop a conceptual model of customer‐focused voice and test it in a hospital setting. Drawing from theory and research on voice, we find that customer orientation and job autonomy are positively associated with customer‐focused voice. In addition, consistent with social information processing theory, these relationships are moderated by service climate, such that a high service climate compensates for the less desirable aspects of employees or their jobs. Finally, we provide evidence for a critical but untested assumption of the voice literature by linking hospital‐level customer‐focused voice to hospital‐level service performance. Results based on data from four unique data sources, provided at varying points in time, and at different levels of analysis demonstrate support for our conceptual model.     

道教在海南黎族地区的传播与民族化

黎族是我国唯一聚居在海南省内的少数民族,信仰以自然崇拜、祖先崇拜为主。汉元封元年(公元前110年),武帝在海南建郡立县,汉文化开始传入海南。由于长期汉、黎民族的历史交往与融汇,汉族本土宗教道教对黎族产生了历史性的影响。道教在黎族地区自唐、宋传入,经元、明两朝,至清代
