Although attentional biases toward body-related information contribute to the etiology and maintenance of body dissatisfaction (BD) and eating disorders (EDs), attentional disengagement in women with BD and EDs is not clear. The present study investigated the association between weight dissatisfaction and attentional disengagement from body-related pictures and the possible moderating effect of body mass index (BMI) on this relation. Two hundred and four undergraduate women engaged in an experiment using a pictorial spatial cueing paradigm including fat/thin bodies and neutral household photos. Partial correlations and simple slopes regression analyses were conducted with attentional disengagement index scores of each category of cues. Findings suggested that independent of BMI, weight dissatisfaction was directly associated with attentional disengagement from both fat and thin pictures. In addition, among women with low and medium BMIs, the more they were dissatisfied with their bodyweight, the more difficulty they had disengaging their attention from fat body pictures. 相似文献

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide. 相似文献

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。 相似文献

Some theories of associative learning imply that time plays a fundamental role in the acquisition process. Consistent with these theories, this paper presents evidence that the time from the onset of a conditioned stimulus (CS) until presentation of the unconditioned stimulus (US) is learned very rapidly at the start of training. We report two autoshaping studies and a study on aversive conditioning in goldfish in which we examine timing at the start of conditioning. We also review data from a number of other conditioning preparations, including fear-potentiated startle, appetitive conditioning in rats, and eyeblink conditioning in rabbits, that report conditioned response (CR) timing early in training. Acquisition speed and the very first expressions of conditioned responding often show sensitivity to the time of US presentation. In instances where temporal control is slowly expressed, it is likely due to performance factors, not to slow learning about time. In fact, the learning about time may be a necessary condition for associative learning. 相似文献

Evidence from a number of family intervention strategies demonstrates a beneficial impact on the course of schizophrenia. It appears that different family interventions have generic features that aid the patient to avoid relapse and improve functioning. A significant challenge for researchers is to modify these generic strategies to be sensitive to different cultural groups in order to ensure their effectiveness. Chinese culture, with its distinct cultural norms governing family interaction and intense stigma towards the mentally ill, would seem to raise a particular challenge.
This paper offers an account of an eclectic model of structural family therapy that incorporates psychoeducation and behavioural treatments for schizophrenia as a theoretical guide to working in a cross–cultural context. A Beijing family, consisting of parents and their daughter with schizophrenia, were seen for sixteen months during a trial of family intervention in China. Through structural family concepts, China's sociocultural context of treatment resource constraints, population policy and stigma are examined and the impact of the illness on family organization is explored. 相似文献

声旁类型与频率在汉字和部件识别中的交互作用 总被引:1,自引:0,他引:1
用识别整字和识别部件两种任务探讨两种声旁频率——组字频率和使用频率的作用。结果发现:在局部识别中声旁使用频率的影响和部件类型有交互作用。声旁使用频率对识别汉字单部件声旁有易化作用。声旁组字频率的影响和部件类型有交互作用。声旁组字频率对识别汉字多部件组合声旁有易化作用。在整字识别中,声旁的使用频率有易化作用;声旁的组字频率的作用受到部件类型的影响,多部件组合声旁的组字频率对识别整字有易化作用。 相似文献

中学生厌学心理及其干预与学习效率的相关研究 总被引:17,自引:1,他引:16
本研究旨在考察两个问题:1.心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2.厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明:心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。 相似文献

该介绍和分析了“相互作用的认知子系统”理论的基本观点,即信息的意义分为具体的、低层次的意义和一般的、高层次的意义;编码形式的转换遵循着特定的规则;不同信息的存储具有各自独立的记忆存储系统:高层次的意义对情绪产生具有直接作用。同时阐述了该理论对抑郁性情绪障碍的研究,并指出了该研究对治疗情绪障碍的意义及存在的问题。 相似文献
