语境与颜色诊断性对句子理解中物体隐含颜色知觉模拟的影响

具身认知理论的代表知觉符号系统认为知识表征具有知觉特点,并假设语言理解中对于所涉及概念及其隐含属性会即时进行知觉模拟。当前研究采用句图匹配范式,通过三个实验探讨句子理解中是否会对物体隐含颜色属性进行知觉模拟及其具体条件。实验1沿用经典范式验证语言理解中对物体隐含颜色存在知觉模拟过程。实验2通过变化句子前语境考察语境是否支持对于物体隐含颜色知觉模拟的影响。实验3进一步考察当颜色属性与其对应物体存在稳定关联时(即具有高颜色诊断性的物体),在不同语境作用下是否会引起知觉表征的变化。研究结果表明,语言理解中知觉模拟过程是灵活的,语境改变会引起读者所激活的物体颜色知觉表征发生变化,并且对于高颜色诊断物体,即使缺乏支持语境,读者仍然会对句中隐含的物体特定颜色进行知觉模拟。     

Coping Card Usage can Further Reduce Suicide Reattempt in Suicide Attempter Case Management Within 3‐Month Intervention

This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3‐month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2‐month and 3‐month intervention periods.     

儿童早期情绪性对学步期父母养育方式的影响

运用追踪设计和分层回归分析, 探究了281名儿童6个月和14个月时的受限后沮丧、恐惧和微笑大笑如何影响24个月时父母养育方式, 以及这种影响是否随儿童年龄增长而变化。研究结果显示:(1)6个月时, 仅受限后沮丧能正向预测24个月时母亲严厉的养育方式, 14个月时受限后沮丧仍能正向预测母亲的严厉, 恐惧也能正向预测母亲的保护担忧, 而微笑大笑能正向预测母亲的接受, 负向预测母亲的严厉和保护担忧;(2)6个月时, 儿童的受限后沮丧能正向预测24个月时父亲的严厉和保护担忧, 14个月儿童的受限后沮丧仍能正向预测24个月时父亲的严厉。     

ADHD儿童的选择性抑制

采用较传统停止信号任务更为精确的选择性停止信号任务,探索ADHD的选择性抑制缺陷的机制。结果发现,ADHD儿童在选择性停止信号任务上,抑制失败的比率明显高于正常儿童,但是其执行加工速度和抑制加工速度与正常儿童没有差异,另外,ADHD儿童表现出了更大的反应变异性。研究认为,ADHD在选择性停止信号任务上的抑制缺陷并非由于抑制加工速度过慢所导致,而是由于其不能很好地维持最佳的激活状态所导致,状态调节理论更能反映ADHD的本质。     

频率差异假设和长时记忆的视优效应

本文包括长时记忆视优效应的三项实验。实验一使用汉语为学习材料,北京人与广东人为被试;实验二使用英语为学习材料、美国人与中国人为被试;实验三使用日语为学习材料、日本人为被试。三项实验都有视觉、听觉两种呈现方式。三项实验的结果都有利于证明频率差异假设,即如果在书面言语中经验某字词的频率高于在口语中经验该字词的频率,则该字词的视觉呈现优于听觉呈现。     

中学生同伴依恋的特点及其与友谊质量的关系:社会交往目标的中介作用

以593名初高中学生为被试, 用问卷法考察中学生同伴依恋的特点, 并探讨同伴依恋与交往目标、友谊质量的关系。结果表明:(1)中学生同伴依恋可分为安全型、专注型、回避型和恐惧型, 它们在中学生群体中的比例分别为34.5%、23.8%、22.1%和19.6%;(2)中学生同伴依恋的年级、性别差异显著:依恋焦虑初二显著高于高一, 依恋回避初一显著高于初二、高一和高二;男生依恋焦虑显著低于女生, 依恋回避显著高于女生;(3)不同依恋类型中学生交往目标、友谊质量差异显著;(4)交往目标中的帮助与支持、亲密性在同伴依恋和总体友谊质量关系中起部分中介作用。     

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。     

反馈对注意缺损多动障碍儿童错误监控能力的影响

研究选取了注意缺损多动障碍(ADHD)儿童39名,正常儿童40名,采用两项选择任务,考察在无反馈和有反馈的情况下,ADHD儿童的错误监控能力是否存在缺损。结果发现,(1)无论是否提供反馈,与正常儿童相比,ADHD儿童的错误察觉能力正常,但是错误更正能力落后,这可能是由于ADHD儿童动作调节控制能力落后导致的;(2)反馈提高了ADHD儿童和正常儿童的认知加工速度,但同时降低了他们的警醒水平,导致错误监控能力下降。     

意识和无意识知觉:注意和刺激特性间的相互补偿

该研究基于Exclusion任务,利用质的差异的研究范式,不仅确立了意识和无意识知觉在行为结果上的质的差异,而且发现刺激特性和注意在决定知觉意识时存在相互补偿的现象。在实验一中,当靶字短暂呈现时。被试用靶字补笔的比率高于基线水平;而当延长靶字呈现时间或提高对靶字的注意水平时,出现反转现象一用靶字补笔的比率低于基线水平。相对应地,在实验二中,分散注意条件下被试用靶字补笔的比率高于基线水平;而当注意集中或在分散注意条件下延长呈现时间时,出现了反转现象。     

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.
