Sex-specific clinical correlates of hoarding in obsessive-compulsive disorder

Little is known about whether the clinical correlates of hoarding behavior are different in men and women with obsessive-compulsive disorder (OCD). In the current study, we evaluated the association of hoarding with categories of obsessions and compulsions, psychiatric disorders, personality dimensions, and other clinical characteristics separately in 151 men and 358 women with OCD who were examined during the OCD Collaborative Genetics Study. We found that, among men but not women, hoarding was associated with aggressive, sexual, and religious obsessions and checking compulsions. In men, hoarding was associated with generalized anxiety disorder and tics whereas, among women, hoarding was associated with social phobia, post-traumatic stress disorder, body dysmorphic disorder, nail biting, and skin picking. In women but not men, hoarding was associated with schizotypal and dependent personality disorder dimensions, and with low conscientiousness. These findings indicate that specific clinical correlates of hoarding in OCD are different in men and women and may reflect sex-specific differences in the course, expression, and/or etiology of hoarding behavior in OCD.     

Prevalence and correlates of hoarding behavior in a community-based sample

Little is known about the prevalence and correlates of hoarding behavior in the community. We estimated the prevalence and evaluated correlates of hoarding in 742 participants in the Hopkins Epidemiology of Personality Disorder Study. The prevalence of hoarding was nearly 4% (5.3%, weighted) and was greater in older than younger age groups, greater in men than women, and inversely related to household income. Hoarding was associated with alcohol dependence; paranoid, schizotypal, avoidant, and obsessive-compulsive personality disorder traits; insecurity from home break-ins and excessive physical discipline before 16 years of age; and parental psychopathology. These findings suggest that hoarding may be relatively prevalent and that alcohol dependence, personality disorder traits, and specific childhood adversities are associated with hoarding in the community.     

数学性别刻板印象的内隐联想测验研究

本研究采用IAT实验设计,考察大学生的内隐数学-性别刻板印象.结果发现,IAT方法能检测到大学生存在"男性比女性更擅长数学"的内隐数学-性别刻板印象;IAT所测量到的内隐数学-性别刻板印象有性别差异,所测得的内隐数学-性别刻板印象没有专业差异; IAT与SEB所测得的结果不相同,IAT和SEB测得的是被试记忆中复杂网络联结的不同方面.

创业失败与再创业意向的作用机制

近年来, 我国政府对创业支持力度不断加强, 创业活动日益活跃, 但失败率却居高不下。如何让创业者在遭遇失败后仍能保持再创业的意向是当前亟待解决的现实问题。拟综合采取横向问卷调查、纵向时间对比以及情景模拟实验的方法, 一方面探讨成就目标导向和社会比较在创业失败和创业失败学习之间的有中介的调节作用; 另一方面分析创业失败学习、创业自我效能感在创业失败和再创业意向之间的链式多重中介作用机制, 寻求由创业失败到再创业意向的不同路径, 这种探讨具有理论创新价值。依据实证研究的结论在实践中指导创业者通过上行比较, 锁定学习目标, 激发再创业意向; 通过提高自我怜悯水平, 使创业者摆脱消极情绪的困扰, 激发掌握性学习动机, 确立再创业的意向, 对于创业者具有重要指导意义。社会比较和自我怜悯的干预研究具有鲜明的中国文化特色。     

Counselor Ethnicity,Counselor Nonverbal Behavior,and Session Outcome With Asian American Clients: Initial Findings

Five Asian American and 5 European American female counselors each saw 3 Asian American volunteer clients for 1 session of career‐focused individual counseling. Examination of counselor nonverbal behaviors revealed that European American counselors displayed significantly greater frequency of adaptors, postural shifts, and smiles than did Asian American counselors. The frequency of smiles was significantly positively correlated with client‐rated session positivity and session arousal, and the frequency of postural shifts was significantly positively correlated with client‐rated session arousal. Limitations and implications of the findings are described.     

发展生产性服务业促进长三角经济发展

境外经济发达国家和地区的服务业为吸纳劳动力的主要行业,而长三角却长期以制造业为吸纳长三角地区劳动力就业的主要产业.最近,服务业吸纳劳动力的绝对数值不断增加,有学者认为长三角地区的服务业正在取代制造业成为吸纳劳动力的主要行业.本文分析指出:在长三角,制造业仍在就业比重中占主导地位;服务业已经连续7年占GDP的比重几乎不变,这是服务业发展停滞、遇到障碍的信号.本文认为这是由于生产性服务业发展不足而造成的结构性问题;发展生产性服务业是促进服务业发展、提高服务业就业率之良策,从而,此举还有扩大长三角内需之经济效果.     

An improved screw-free method for electrode implantation and intracranial electroencephalographic recordings in mice

We recently developed a glue-based method for the implantation of intracranial electrodes in mice. Our approach is to secure a preconstructed electrode array using a cyanoacrylate-based glue (similar to Krazy Glue). This method is applicable to both young and aging mice and is suitable for long-term electroencephalographic recordings. In the present experiment, we explored whether the glue-based method is capable of securing individual electrodes in addition to securing the electrode array. C57 black mice aged 25–35 days or 13–19 months were operated on under isoflurane anesthesia. Monopolar or bipolar electrodes were inserted independently in the ipsilateral hippocampal CA3 and entorhinal cortical areas, and they were fixed onto the skull using the glue together with dental acrylic, but without anchoring screws. We found that the implanted electrodes were stable and allowed repeat intracranial recordings and electrical stimulation in freely moving mice.     

情绪信息的多通道整合

自然环境中人类情绪信息的交流是依靠多个感觉通道实现的,多通道整合是情绪加工的基础。近年来的行为学、电生理学与神经成像的研究表明,情绪信息的加工具有跨通道自动整合的特点,它发生在认知加工的早期阶段,与颞上回、颞中回、海马旁回和丘脑等脑区密切相关。不同情绪的整合既有共同的神经基础,又有各自独特的加工区域。情绪信息的整合机制还可能与加工类型及注意资源有关。在未来研究中,实验的标准化、动态化、自然化有助于提高研究的准确性和研究间的可比性,而对特殊群体的研究,以及综合研究情绪加工与注意等其他认知过程则有助于我们进一步探索多通道整合的神经机制。     

节律在听觉言语理解中的作用

言语理解是听者接受外部语音输入并且获得意义的心理过程。日常交流中,听觉言语理解受多尺度节律信息的影响,常见有韵律结构节律、语境节律、和说话者身体语言节律三方面外部节律。它们改变听者在言语理解中的音素判别、词汇感知以及言语可懂度等过程。内部节律表现为大脑内神经振荡,其能够表征外部言语输入在不同时间尺度下的层级特征。外部节律性刺激与内部神经活动的神经夹带能够优化大脑对言语刺激的处理,并受到听者自上而下的认知过程的调节进一步增强目标言语的内在表征。我们认为它可能是实现内外节律相互联系并共同影响言语理解的关键机制。对内外节律及其联系机制的揭示能够为理解言语这种在多层级时间尺度上具有结构规律的复杂序列提供了一个研究窗口。
