两例先天性无痛症患者的心理生理特点研究 Ⅱ.对致痛性强刺激的知觉和反应

本工作对两例先天性无痛症患者对于致痛性强刺激的知觉和反应进行了研究(例1女,10岁,例2男,13岁)。对照组为20例正常儿童,性别和年龄均与患儿相匹配。 结果:1),生活中痛:两例患儿均无(包括痛感觉和痛反应)。2)实验性痛:①痛感觉:两例患儿均无;②“痛”反应:例1有“痛”反应(脉搏和呼吸的变化以及行为反应明显,大致与正常儿童相似)。例2无“痛”反应(脉搏和呼吸的变化轻微,无行为反应,与正常儿童不同)。 由结果看来,先天性无痛症患者似乎可分为两种类型:不完全型(如同例1)和完全型(如同例2)。存在有“痛”反应而无痛感觉的无痛症患者。 本工作结果从另一侧面为痛的两成分学说提供了依据。     

Training Mental Health Professionals to Assess and Manage Suicidal Behavior: Can Provider Confidence and Practice Behaviors be Altered?

Remarkably little systematic research has studied the effects of clinical suicidology training on changing practitioner attitudes and behaviors. In the current study we investigated whether training in an empirically‐based assessment and treatment approach to suicidal patients administered through a continuing education workshop could meaningfully impact professional practices, clinic policy, clinician confidence, and beliefs posttraining and 6 months later. At the 6 month follow‐up we found that 44% of practitioners reported increased confidence in assessing suicide risk, 54% reported increased confidence in managing suicidal patients, 83% reported changing suicide care practices, and 66% reported changing clinic policy. These results suggest that a brief and carefully developed workshop training experience can potentially change provider perceptions and behaviors with a possible impact on clinical care therein.     

人文主义与科学主义在中医现代化研究中的冲突

因中医学的核心概念未能获得现代科学意义上的实证,所以有人提出科学主义应当从中医学研究中退出,取而代之的应当是人文主义。

The school psychologist as expert witness in due process hearings

As a consequence of the Consent Agreement reached between the Pennsylvania Association for Retarded Children and the Commonwealth of Pennsylvania in the United States District Court for the Eastern District of Pennsylvania, school of psychologists are finding themselves increasingly in the role of expert witness in due process hearings. The paper identifies a number of problems regarding the witness behavior of psychologists in these hearings and proposes some recommendations and resolutions.     

Drugs,Sex, and Condoms: Identification and Interpretation of Race‐Specific Cultural Messages Influencing Black Gay and Bisexual Young Men Living with HIV

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being.     

阅读中自然学习生词的实验研究

本研究对儿童阅读时从语境中自然学习生词的过程及其多个影响因素进行了探讨。301名三、五年级小学生参加了实验。首先要求他们阅读文章,然后测验他们对文章中生词的知识。本研究在不同年级和能力的儿童中都发现了显著的自然学习效应。结果还表明,词的概念难度、词结构的语义透明度、语境线索强度和儿童课外阅读量对儿童的自然学习有重要影响。     

关于进化论的生命科学质疑

现代科学远未弄清楚生命是什么,所以,肯定生命是偶然生成的观点是不符合时代的科学精神的。遗传变异不能产生新的物种,也没有证据表明基因突变导致生物进化产生了新物种。按照小群突变的新达尔文主义来推断人类进化,既缺乏事实根据,也有悖于逻辑推理。
