青少年网络游戏行为的心理需求研究

在质的研究及理论分析的基础上,构建了16-24岁青少年网络游戏行为的心理需求模型,然后根据该模型编制问卷,进行了量的研究。探索性与验证性因素分析的结果表明:(1)青少年网络游戏心理需求问卷由现实情感的补偿与发泄、人际交往与团队归属、成就体验三个维度组成,具有良好的信度和效度指标,可以施用;(2)青少年对网络游戏的心理需求程度与其对网络游戏的使用程度显著相关。

樟柳碱所致学习和记忆障碍动物模型的探讨

本实验采用水迷津法、步下法和步入法,用樟柳碱制备学习和记忆障碍的动物模型。结果表明,樟柳碱(10毫克/公斤)可使小鼠引起学习障碍,其表现为通过水迷津全程的时间延长,而且小鼠进入盲路的错误次数明显增多。樟柳碱(10毫克/公斤)可使小鼠引起记忆障碍,在樟柳碱的影响下,小鼠步下平台或步入暗箱的潜伏期明显缩短,并使它们的错误次数增多。本实验结果进一步表明,测定小鼠的记忆障碍,步入法似乎比步下法更为敏感。     

生物反馈、肌肉放松与高血压

本文旨在了解生物反馈与高血压病的关系,以临床客观指标探索它们之间的差量。随意选择高血压病者39名,分为三个组:单纯生物反馈组,肌肉放松训练组以及生物反馈辅助肌肉放松训练组。经一个月训练结果表明:单纯生物反馈组收缩压与舒张压的疗效有非常显著性差异水平。肌肉放松组仅收缩压疗效有统计学意义,舒张压不呈现差异水平。生物反馈辅助肌肉放松训练组两种血压疗效与单纯生物反馈组类似。这说明单纯生物反馈在治疗高血压中起主要作用。肌肉放松有很强的局限性。     

Rheumatoid arthritis is associated with negatively variable impacts on domains of female sexual function: evidence from a systematic review and meta-analysis

To systematically review the literature to identify the impact of rheumatoid arthritis (RA) on specific female sexual function domains. A meta-analysis was performed and the related literature were searched in MEDLINE, EMBASE, Cochrane Library, CNKI, CBM and Web of Science databases, and in reference lists of articles and systematic reviews. Score of the Female Sexual Function Index (FSFI) was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 346 women with RA and 237 healthy female controls. Each domain of the FSFI score: lubrication (MD, ?2.48; 95% CI, ?3.69, ?1.28), orgasm-1.71 (?2.09, ?1.33), sexual desire-1.27 (?1.59, ?0.95), satisfaction-1.67 (?2.18, ?1.16), arousal-1.83 (?2.85, ?0.82), pain-1.57 (?2.43, ?0.70) and the total score ?8.84 (?11.88, ?5.79) were lower in RA women than healthy controls. Furthermore, lubrication dimension was most severely affected especially. This meta-analysis showed that female RA patients scored lower in each dimension of FSFI, mostly in the lubrication domain. It demonstrated that targeted interventions should be done to improve their sexual function. Future well-designed researches with larger sample sizes are necessary to evaluate the potential risk factors which determine female sexual dysfunction.     

国外心理契约破坏及结果变量与调节变量：述评与展望

心理契约破坏是个体对组织未能履行其在心理契约中应承担责任的认知评价。文章首先结合以往研究探讨了心理契约破坏与相应结果变量的关系,然后探讨了调节变量的作用,最后从被试群体、研究方法及理论模型的构建上对未来研究进行了展望。     

Predicting change in adolescent adjustment from change in marital problems

The present prospective, longitudinal study of 451 adolescents and their parents extends earlier research by investigating whether change in marital problems predicts change in adolescent adjustment, after controlling for other marital problems and socioeconomic status. Latent growth curves over a period of 5 years were used, and the results revealed that in general, increases or decreases in marital distress and conflict predicted corresponding increases or decreases in adolescent adjustment problems over time. In addition, the analyses suggested that increases in marital distress are as harmful for adolescent adjustment as increases in marital conflict.     

铁路灯光信号显示的一些研究

铁路色灯信号不论在白天或夜间都指挥着列车的运行,其显示好坏直接关系到列车的安全和效率。影响色灯信号显示的因素很多,如光源参数,光系统结构,灯光散角,天气好坏等。而色灯信号的颜色,观察距离(或视张角)以及亮对比度是人对信号识别的三个较重要因素,所以我们想从这三个方面来讨论信号灯光显示问题。     

情绪调节灵活性对负性情绪的影响：来自经验取样的证据

情绪调节灵活性是指个体根据不断变化的情境需求灵活部署情绪调节策略的能力。本研究采用经验取样方法,通过拟合个体在日常生活事件(如,未通过考试)和突发公共卫生事件(COVID-19)中的策略使用剖面结构和情境负性程度与策略使用程度的共变关系测量个体的情绪调节灵活性水平,并探讨其对个体后续负性情绪(抑郁和焦虑)的影响。两个独立样本结果表明：单一策略使用偏好(如沉浸偏好和表达抑制偏好)的个体在负性生活事件中和疫情期间经历了更高水平的抑郁和焦虑情绪。此外,当个体随情境负性程度提高使用更多分心策略,而随情境负性程度降低使用更多认知重评策略(意味较高的情绪调节灵活性),其抑郁和焦虑情绪水平更低。以上结果共同证实了情绪调节灵活性有利于减少个体的负性情绪体验。
