When knowledge is not enough: the phenomenon of goal neglect in preschool children

We argue that the concept of goal neglect can be fruitfully applied to understand children's potential problems in experimental tasks and real-world settings. We describe an assessment of goal neglect developed for administration to preschool children and report data on two measures derived from this task alongside the Dimensional Change Card Sort (DCCS) and an opposite color response inhibition task. The propensity to neglect initial task cues was uniquely linked to response inhibition, whereas neglect of a later cue was uniquely linked to the DCCS. Additional evidence suggests that recovery from neglect can occur and shows that goal neglect varies with the cognitive transparency of the signifying cue. Data demonstrate the importance of, and place constraints on, current theories of information regulation and foreground the notion of graded representations in working memory and executive functioning.     

No-harm contracts: a review of what we know

Few events in the practice of a mental health clinician can be as devastating as the suicide of a client. Although suicide is a rare occurrence, clinicians face assessment of clients' risk for harming themselves on a regular basis. One well-accepted and widely practiced intervention for suicidal ideation is the use of no-harm contracts (NHC), although opinions about NHCs range from enthusiasm to apathy. The existing research does not support the use of such contracts as a method for preventing suicide, nor for protecting clinicians from malpractice litigation in the event of a client suicide.     

吗啡行为及条件性行为敏感化效应及其个体差异

目的：考察吗啡处理下,大鼠行为敏感化及条件性行为敏感化效应及其个体差异性表现。方法：根据大鼠在初次抵达的新颖环境中水平活动量的高低,将大鼠划分为高反应大鼠（High responder, HR）和低反应大鼠（Low responder, LR）,应用自动监测大鼠活动箱,分别考察HR和LR大鼠在行为及条件性行为敏感化效应表达上的差异。结果：（1）连续5天吗啡给药,LR大鼠活动量显著升高,HR大鼠无此效应;（2）条件测试日（第6天）,给药与环境匹配大鼠,活动量较给药与环境非匹配组动物和对照组动物显著为高;此效应在HR和LR大鼠同时存在;（3）从给予吗啡到给予盐水,发现LR大鼠活动量显著下降,而HR大鼠活动量无显著改变。结论：在连续给药下,LR大鼠较HR大鼠,在行为敏感化效应的形成中,具有更为显著的效应,此效应为LR动物对吗啡更高的药物效应,而非条件效应所致,同时HR和LR大鼠都可以对吗啡条件性线索产生应答,产生条件性行为敏感化效应。     

何以近朱者赤、近墨者黑?特质激活理论的缘起、现状和未来

特质激活理论旨在阐明适宜的外部情境如何激活个体的内在特质, 以及这种激活如何促使潜藏的隐性特质表达出显性的行为。文章综述了特质激活理论, 剖析了其从思想诞生到基准模型, 再到拓展模型的两次飞跃, 重点阐释了情境分层、情境特征、激活后果的反馈等系统, 辨析了特质激活的内涵及其与“人-环境”匹配理论、与情境强度理论的异同, 从深化验证、拓展现有理论模型等视角提出未来研究走向。     

不同相关线索下海洛因成瘾者的反应差异及反应抑制特征：来自ERP的证据

采用ERP技术, 探究海洛因成瘾者在不同相关线索下的脑电反应及其与冲动性的关系。实验采用组间实验设计和双选择Oddball范式, 要求海洛因成瘾组和健康对照组被试对标准刺激与偏差刺激分别做不同的按键反应, 记录他们的EEG数据。结果发现：相比对照组被试, 海洛因成瘾者在观看药物相关线索时诱发的N2波幅更小, P3波幅更大; 在成瘾组内, 相比用药工具线索, 用药动作线索诱发了更小的N2波幅和更大的P3波幅。这表明海洛因成瘾者对药物相关线索存在反应抑制缺陷, 且不同的药物相关线索会激发海洛因成瘾者不同程度的反应抑制缺陷, 用药动作线索比用药工具线索更大程度地影响成瘾者的反应抑制能力, 反映出更高的动作冲动性。     

Chinese Landscape Painting and the Study of Being: An Imagined Encounter Between Martin Heidegger and Xia Gui

In this paper, we pose a speculative encounter between Heidegger and the Chinese Song Dynasty landscape painter Xia Gui. Our intention is to reassess Heidegger’s theory of the fourfold. By placing the concept in a cross-cultural context, we argue that Heidegger was essentially correct in that the world is structured as a fold between interrelated elements. At the same time, we challenge the quantity and quality of the folded elements. If one turns to the work of Xia Gui in conjunction with relevant Daoist texts, what one finds is a threefold structure to the world, composed of earth, sky, and mortals without Heidegger’s emphasis on divinities. In conclusion, we suggest that studying the folding structure of the world ought to be done through cultural comparisons of philosophical and aesthetic traditions in order to understand the potentiality for worldhood as an xfold.

Sexual Minority Stress and Social Support Explain the Association between Sexual Identity with Physical and Mental Health Problems among Young Lesbian and Bisexual Women

Bisexual women report more physical and psychological health problems than lesbian women do, which may be attributed to greater sexual minority stress and less social support. However, many studies combine lesbian and bisexual women into a single group. The current study examined if sexual minority stress and social support mediated the association between women’s sexual identity (lesbian or bisexual) and health-related outcomes. A total of 650 U.S. young adult lesbian (n?=?227) and bisexual (n?=?423) women completed an online survey about sexual minority stress, social support, and physical and mental health problems. Bisexual women reported more physical and mental health problems. A sequential mediation model showed that bisexual women reported greater sexual minority stress than lesbian women, which in turn was associated with less social support, which was associated with more physical and mental health problems. Greater sexual minority stress and lower social support may help explain why bisexual women report more health-related problems than lesbian women. The results of the present study support the importance of examining risk and protective factors for health problems separately for lesbian and bisexual women. Health-related intervention programs that target sexual minority women may need to be tailored differently for lesbian and bisexual women.

     

Peer interaction and maltreated children: Social network and epigenetic models

The epigenetic and social network models of social development are discussed. The relative efficacy of the two approaches is put to empirical test by examining the relationship between inadequate attachment relationships and subsequent peer interaction. Infants in a day care center who either had or had not experienced maltreatment were observed with their mothers and with peers. The social network model was supported in that there were few differences between maltreated and non-maltreated infants on peer interaction behavior while the expected differences obtained on mother-infant interaction variables. The use of day care for maltreated children is recommended.
