Using words instead of jumbled characters as stimuli in keyboard training facilitates fluent performance

Keyboarding skill is an important target for adult education programs due to the ubiquity of computers in modern work environments. A previous study showed that novice typists learned key locations quickly but that fluency took a relatively long time to develop. In the present study, novice typists achieved fluent performance in nearly half the time when words rather than jumbled characters were used as stimuli. This suggests that using real words in the keyboarding program can enhance the efficiency of training.     

Posttraumatic Stress Disorder Symptom Structure in Chinese Adolescents Exposed to a Deadly Earthquake

This present study examined the structure of posttraumatic stress disorder (PTSD) symptoms in a large sample of Chinese adolescents exposed to a deadly earthquake. A total of 2,800 middle school students aged 12 to 18 years participated in the study 6 months after the “Wenchuan Earthquake”. Results of confirmatory factor analysis indicated that a five-factor intercorrelated model composed of intrusion, avoidance, numbing, dysphoric arousal, and anxious arousal, fit data significantly better than both the four-factor numbing model King et al. (Psychological Assessment 10:90–96, 1998) and the four-factor dysphoria model Simms et al. (Journal of Abnormal Psychology 111:637–647, 2002). Further examination of the external convergent and discriminant validity revealed that except for the dysphoric arousal factor, the remaining four PTSD factors yielded significantly different correlations with external measures of anxiety vs. depression. The findings add to the limited literature on the factor structure of PTSD in youths and on the five-factor PTSD model. In addition, they provide more detail into the latent psychopathological processes of PTSD, and inform the forthcoming DSM-5.     

正确对待胸腔镜在肿瘤手术中的应用

以胸腔镜为代表的微创胸外科迅速发展并取得了良好的临床效果。胸腔镜手术治疗肺癌和食管癌存在较大争议,全盘否定或盲目应用都会影响胸外科的发展。胸腔镜肺癌、食管癌切除术都有其适应证,对医生提出了更高的技术要求。     

配对联想学习能力和语音意识在汉语儿童早期阅读中的作用

本研究以93个学前儿童为研究对象,考察了配对联想学习能力和语音意识在汉字阅读和词汇发展中的作用及其相互关系,其中,配对联想学习分为假词、非词、符号三种形式。结果发现,语音意识是解释汉字阅读的最重要变量,配对联想学习能力对词汇发展具有独特贡献;不会阅读者在假词和非词学习中比初学阅读者差,而在非语言的符号学习中没有差异。     

优势分析方法及其应用

优势分析是近年来由Budescu等人新发展起来的一种确定多元回归方程中各预测变量相对重要性的方法。与传统方法相比,优势分析突出的特点是,全面比较了在由全模型所衍生出来的所有子模型情况下,各预测变量(X1,X…XP)在解释或预测标准变量у时,它们之间的相对重要性。本文从基本原理以及具体操作过程对这一新的统计分析方法进行了详细介绍。

Human values priorities: effects of self-centredness and age

This study aims to assess the effects of the degree of self-centredness/selflessness and age on human values priorities according to Schwartz model. This model displays two main dimensions which oppose on one hand, self-enhancement to self-transcendence and on the other hand, openness to change to conservation. The sample consisted of 307 adults aged 18 to 65 who filled in two questionnaires: the Self-Transcendence Inventory (STI) and the Questionnaire of Values by Portraits (QVP). The results show that the more people were selfless, the more they gave greater importance to self-transcendence and less importance to self-enhancement; and inversely. Moreover, the older the participants were, the more they valorised collective values compared to individual values. Finally, age appeared as a more relevant predictor of values priorities than the degree of self-centredness. Such results could be of first importance in terms of designing moral education strategies.     

Establishing an Alcohol and Other Drug Assessment and Intervention Program Within an On‐Site Counselor Education Research and Training Clinic

The authors describe the Substance Information Program, a university alcohol and other drug (AOD) assessment and intervention program. The Substance Information Program is housed in a counseling department's on‐site training and research clinic and gives counselors‐in‐training an opportunity to gain practical addictions training.
