Sex and age-related anxiety in a community sample of Norwegian adolescents

The first aim of this study was to estimate the prevalence of anxiety and DSM-related anxiety symptom-clusters among adolescents (13-19 years of age) in middle Norway. A second aim was to examine the developmental trajectories of anxiety symptoms for boys and girls during adolescence. In a cross-sectional study, 1,802 students in junior high schools and high schools in the Mid-Norway Health Region filled out a questionnaire (a response-rate of 77%) including the SCARED self-report form (Birmaher et al., 1997) during one school hour. In line with findings of previous studies, girls reported higher anxiety-levels than did boys. A large gender-specific increase in anxiety in 14-15-year-old girls was also found. Apart from this age-specific effect, the results indicated a general reduction in anxiety during adolescence for all symptom groups except generalized anxiety and school phobia. The high anxiety levels in girls aged 13 to 14 years implicate a need for caution by clinicians because such high anxiety levels may be mistaken for the existence of an anxiety disorder. The rapid increase in anxiety symptoms among girls in early adolescence may reflect a heightened sensitivity in this age group, and may have implications for when to implement secondary prevention programs.     

从西地那非的研发过程探讨医学研究的规律

西地那非研制成功20余年,用于治疗男性勃起功能障碍（erectile disorder,ED）。而近几年来,越来越多的证据表明西地那非可以明显降低各种原因所导致的肺动脉高压（pulmonary arterial hypertension,PAH）。西地那非对肺动脉高压的治疗作用,再次引起了人们对西地那非进行深入研究的兴趣。西地那非的研究历程给人们带来很多有益的启示。     

1秒以上时距判断的ERP研究

以视觉呈现时距信号,采用时间泛化范式要求被试判断5种探测时距(1～4秒)与标准时距(2秒)之间的长度关系,并记录11名大学生在时距判断过程中的事件相关电位(ERP),继而探讨不同探测时距条件下CNV波幅特征变化以及左、右侧额叶在时距判断中的功能。结果发现:1秒、1.42秒以及2秒条件下,CNV波幅峰出现在探测时距结束点,2.84秒、4秒条件下,CNV波幅峰出现在大约2秒处(标准时距);CNV负性翻转至基线位置在1秒、1.42秒、2秒条件下随探测时距的增长而延后,而在2.84秒、4秒两种条件下无显著差异;左、右侧额叶处诱发的CNV波幅峰潜时在2.84秒、4秒探测时距条件下无显著差异,且均在2秒附近。这说明在1秒以上视时距判断中CNV波幅峰反映了基于记忆中标准时距的时距判断的决策过程;CNV负性翻转至基线位置与时距判断的决策阶段存在共变关系,CNV负性翻转至基线位置相当于负荷解脱过程中的一个由负翻正的转折点;左、右侧额叶均参与了时距脉冲累加过程。     

Episodic Memory in Adult Age and Effects of Sibship Size and Birth Order: Longitudinal Data

This study examined the effects of sibship size and birth order on episodic memory performance in adulthood and old age. Participants were 1,141 healthy individuals aged 35–80 years, who took part in a longitudinal project on age, health, and memory. Episodic memory measurements over a 5-year interval included tests of recognition (recognition of faces, family names, first names, and nouns) and tests of recall (free recall of sentences, free recall and cued recall of nouns, and recall of activities). Results showed significant effects for both recall and recognition, that is, the smaller the sibship size is for an individual and the earlier born, the better memory performance. These results demonstrate that the effects of sibship size and birth order previously shown in children and adolescents (Belmont and Marolla, Science 182:1096–1101, 1973; Zajonc and Markus, Psych Rev 82:74–88, 1975; Zajonc, Am Psychol 56:490–496, 2001) are robust over time and hold over a large adult range.     

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.     

Education and Psycho-Utopianism—Comenius,Skinner, and Beyond

In the history of ideas some researchers have recently coined the term psycho-utopianism, denoting the notion that the ideal society presupposes a “new man,” that is, the psychological nature of man must change before society can change. Cultural studies have noted this line of thinking also within the so-called New Age movement. However, the notion of a New Age is not really new; it occurred already at the beginning of the Modern Epoch; in seventeenth-century Europe. At that time, the educational philosopher J. A. Comenius was writing his canonical work Didactica Magna and other texts on education, science, and philosophy, with the ultimate aim of contributing to a new world order. Comenius was one of the first modern educators to argue for a general education of both boys and girls irrespective of social class. Three hundred years later, B. F. Skinner suggested psychological methods of education and upbringing, also with the ultimate aim to transform society. In this article I will look closer at the similarities and differences between these two thinkers regarding their psycho-utopian notions. I will conclude with similar reflections on psycho-utopian tendencies in present discourses on information and communication technology (ICT) and education.
