Infant-mother attachment can be improved through group intervention: a preliminary evaluation in Spain in a non-randomized controlled trial

The quality of infant-mother attachment has been linked to competence in different domains of child development. Research indicates that early intervention can enhance the quality of infant-mother attachment, though its efficacy in a group format has yet to be evaluated. The current study is aimed at examining the usefulness of a group intervention in enhancing infant-mother attachment. An intervention aimed at addressing aspects such as maternal responsivity, sensitivity and childrearing behaviour was developed by the researchers and experienced psychologists. The intervention spanned a period of 14 months starting from the third quarter of pregnancy. The intervention was evaluated among 24 mothers from the Basque region of Spain. The sample consisted of children of both genders in a similar proportion: 45.8% were boys and 54.2% were girls. The children in this sample were full-term born and did not present symptoms of any serious pre- or postnatal complications. The intervention had a statistically non-significant medium effect. Infants whose mothers had received the intervention showed higher rates of secure attachment compared to children from the control group, as assessed by the Strange Situation observation procedure. A potentially significant confounding variable, maternal attachment, was balanced across the intervention and comparison groups. We can tentatively point out that a group intervention may enhance the quality of infant-mother attachment. Nevertheless, because the study design was not randomized, the results of this study remain preliminary and need replication in a full randomized controlled trial designed study.     

自我关注重评和情境关注重评情绪调节策略及对随后认知控制的影响

认知重评作为高度适应性的情绪调节策略, 是否消耗随后任务所需的认知资源仍存在争议。以往研究把重评作为单一策略研究, 并未区分重评亚型对这一问题进行探索。本研究采用情绪调节与认知控制结合的任务, 考察自我关注和情境关注两种重评亚型调节情绪的效果, 以及对随后认知控制的影响是否存在差异。结果发现两种重评策略都能有效调节情绪, 但调节效果存在差异。从行为角度看, 与中性刺激相比, 负性刺激会引发更高的负性情绪水平, 对随后冲突任务的认知控制能力更差。进一步从神经机制水平来看, 增加负性情绪可能会进一步消耗随后任务可用的认知资源, 与自我关注重评相比, 采用情境关注重评降低负性情绪后, 对随后冲突任务的认知控制能力更强。说明两种重评亚型并不同质, 不仅在调节情绪的效果上存在差异, 而且会引发不同的认知控制后果; 同时, 负性情绪水平越高, 认知控制能力可能会越差。     

肿瘤疫苗治疗肿瘤的前景

肿瘤疫苗的发展已经历了一个多世纪,20世纪50年代,人们开始了自体肿瘤疫苗的研究.使肿瘤疫苗(主动性免疫治疗)成为继手术、放疗、化疗之后的肿瘤治疗方法.肿瘤疫苗作为主动特异性免疫治疗,在临床中起到越来越重要的作用,人们开始尝试利用多种方法制备肿瘤疫苗并利用其促进机体免疫应答,从整体细胞,分子水平调控机体对肿瘤的免疫.目前肿瘤疫苗的研制已取得很大进展,给人类战胜肿瘤提供很大希望。     

Major life events and major chronic difficulties are differentially associated with history of major depressive episodes

Major life events have been found to precede onsets of a 1st lifetime episode of depression more commonly than subsequent recurrences. Despite general empirical support for this finding, few data directly address how the role of major life events may change over successive recurrences. Further, little research has examined major chronic difficulties in relation to a 1st lifetime episode versus a recurrence of depression. The present study tested the associations between major life events and major difficulties in relation to lifetime history of depressive episodes in a sample of 96 individuals diagnosed with major depression. Using investigator-based measures of life stress, the authors found that, whereas major life events were associated with fewer lifetime episodes, major chronic difficulties were related to more prior episodes. These findings are discussed in terms of underlying mechanisms that may account for the changing role of major life stress over successive recurrences of depression.     

外科感染:古老的疾病严峻的挑战

外科感染是人类最古老的疾病,在控制外科感染方面我们已经取得了巨大的进步,但外科感染反而变得越来越复杂,我们面临的挑战也越来越严峻.面对挑战,我们应该采取全方位的对策.     

普通高中实施选修课的心理认可度及其影响因素——基于宁波市教师与学生群体的调查分析

以宁波市三种类型六所普通中学为样本,以学生群体和教师群体为对象,采用问卷评定法,以心理认可度为指标,探讨了普通中学师生对于实施选修课制度的主观评价及其相关因素.结果发现：整体而言,学生和任课教师对宁波市普通高中实施选修课的心理认可度较高;存在的主要问题,是学生对选修课学习效果的认可度较低,而教师对学校开展选修课的教学条件的认可度较低,且认为实施选修课制度的外部阻力较大;特色类和融通类学校落实选修课制度的观念性阻力较大;中老年教师对开设选修课的适应性较低.进一步完善选修课制度,需要从教师、学校和政府三个方面形成合力,共同推动旨在促进学生个性化发展的选修课制度的健康发展.     

群体共同经历影响不公平感知

以往研究考察了不公平经历如何影响个体的认知、情绪及行为。然而, 这些研究着重于考察个体“独自经历”不公平的现象, 而尚未有研究考察, 当个体与他人以群体身份共同经历不公平时, 不公平经历对个体的影响。3项实验采用改编的三人最后通牒博弈任务考察“群体共同经历”不公平如何影响个体的不公平感知。研究结果表明, 无论是通过“共同命运” (实验1)、轮流为群体做决策(实验2), 还是招募成对朋友(实验3)来操纵或凸显群体身份, 群体共同经历不公平, 相比独自经历不公平, 均显著降低(而非提升)了被试的不公平感知。研究结果对于社会及组织管理具有借鉴意义。
