Evidence for an emotion-cognition interaction in the statistical prediction of suicide attempts

Suicidal behavior is a prevalent problem among adolescents and young adults. Although most theoretical models of suicide suggest that this behavior results from the interaction of different risk factors, most prior studies have tested only bivariate associations between individual risk factors and suicidal behaviors. The current study was designed to address this limitation by testing the effect of an emotion–cognition interaction on suicide attempts among youth. Specifically, we hypothesized that the interaction of emotion reactivity and problem-solving skills would statistically predict the probability of a recent suicide attempt among 87 adolescents and young adults. Results revealed a significant interaction, such that emotion reactivity was strongly associated with the probability of a suicide attempt among those with poor problem-solving skills, moderately associated among those with average problem-solving skills, and not significantly associated among those with good problem-solving skills. The next generation of studies on suicidal behavior should continue to examine how risk factors interact to predict this dangerous outcome.     

管子社会控制思想及其现实意义

齐国法家及其代表论著《管子》中包含着丰富的社会控制思想。《管子》一书在顺民心的前提下,主张运用法治制衡,培养民众礼节来进行社会的合理控制。在整个中国古代历史上,《管子》所倡导的礼法结合的社会控制手段是最为有效完善的。《管子》从治国实践的角度认为,要真正做到"以民为本",对国家和百姓进行合理的控制安排,实现百姓安居,国家长治,在治国方略上就必须礼法并用,德法并举:一方面以法来维护人民的利益,另一方面以"礼"来维护社会秩序。《管子》礼法并举的社会控制思想在构建和谐社会、减少社会道德失衡等方面具有重要的现代价值及意义。     

Multistable perception: when bottom-up and top-down coincide

During prolonged observation of an ambiguous figure sudden perceptual reversals occur, while the stimulus itself stays unchanged. There is a vivid debate about whether bottom-up or top-down mechanisms underlie this phenomenon. In the present study, we investigated the interrelation of two experimental factors: volitional control and discontinuous stimulus presentation. Both factors strongly modulate the rate of perceptual reversals and each is attributed either as top-down or bottom-up. We found that participants can apply specific strategies to volitionally increase and/or decrease the stability duration of each of the possible percepts according to the experimental instructions. When attempts of volitional control are combined with discontinuous stimulus presentation the effects are fully additive. Our results indicate that perceptual reversals can originate from different neural mechanisms on different time scales.     

父母心理控制与小学生的欺负行为:敌意归因和冷酷无情的作用检验

采用班级整群抽样法选取1847名3~6年级小学生（男生987名;平均年龄10.73±1.16岁）及其家长为被试,采用问卷法考察父母心理控制与小学生欺负行为的关系,同时探讨敌意归因和冷酷无情的中介作用。结果发现：（1）父母心理控制显著正向预测小学生的欺负行为;（2）冷酷无情在父母心理控制与小学生欺负行为间的关系中存在中介作用,敌意归因不发挥中介作用;（3）父母心理控制对小学生欺负行为影响的中介机制不存在显著的性别差异和学段差异。本研究结果表明,冷酷无情是父母心理控制影响小学生欺负行为的重要机制,但敌意归因不是。研究者和实践者应注重对欺负者情感加工能力的关注和干预。     

大学生心理控制感对心理健康水平影响的研究

本研究采用《心理卫生症状自评量表SCL-90》和《内控性、有势力他人和机遇量表》对300名大学生进行测试,探讨大学生心理健康与心理控制感的关系。结果表明：大学生在SCL-90中至少有一个因子得分大于或等于3分的占学生人数的25．33％,在性别和年级之间心理控制感和心理健康均不存在显著差异,大学生心理健康水平低于全国正常成人常模;父母的文化和职业等社会因素对心理健康和心理控制感水平会产生一定的影响;与心理内控倾向者相比,心理倾向于外在控制的人正性情感少,负性情感多,精神症状多,总体心理健康水平低。

抑制性控制在幼儿执行功能与心理理论中的作用

将执行功能任务和心理理论任务中的共同成分——抑制性控制区分为3个不同的难度水平,从而构成心理理论任务（错误信念）的3个变式A1、A2、A3和执行功能任务（白天/黑夜）的3个变式B1、B2、B3。实验1以48名4岁幼儿为被试,探讨对两类任务中各自的3个变式所包含的抑制性控制的难度区分的适当性,结果表明幼儿在两类任务中各自的3个变式上的正确率差异显著,说明其抑制性控制的确表现出了高、中、低3个不同的难度水平;实验2根据实验1所设计的两类任务,以144名3~6岁幼儿为被试,探讨了不同抑制性控制的难度水平在幼儿执行功能和心理理论的相关中的作用,结果表明抑制性控制的难度水平是影响幼儿执行功能与心理理论的相关的一个重要因素。     

The CIOMS view on the use of placebo in clinical trials

Based on worldwide consultations with experts in science and ethics the revised CIOMS 2002 International Ethical Guidelines for Biomedical Research Involving Human Subjects provide guidance on when the use of placebo as a comparator in clinical research is ethically acceptable. The article reviews the main points of the CIOMS Guidelines and commentaries including the use of placebo in situations where the best current method is available and the relation of placebo to established effective intervention. It discusses the use of placebo in externally sponsored research in low-resource countries and requirements for informed consent related to placebo studies. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.     

The attentional window configures to object and surface boundaries

Attention can select items based on location or features. Belopolsky and colleagues posited the attentional window hypothesis, which theorized that spatial and featural selection interact such that featural selection occurs within a “window” of spatial selection. Kerzel and colleagues recently found that the attentional window can take complex shapes, but cannot configure around non-contiguous locations. The current experiments investigated whether perceptual grouping cues, which produce perceptual objects or surfaces, enable the attentional window to configure around non-contiguous locations. Using the additional singleton paradigm, we reasoned that observers (1) would be slowed by a colour singleton distractor that appears within the observers’ attentional window and (2) would be unaffected by distractors that do not appear within the attentional window. In separate blocks of trials, a target appeared upon one of two objects. Observers were cued to the relevant surface, and we asked if responses were affected by distractors on the cued task-relevant surface, and on the uncued irrelevant surface. Colour singleton distractors slowed responses when they appeared on the cued surface, even when those locations were non-contiguous locations. Distractors on the irrelevant surface did not affect responses. The results support a highly adaptable attentional window that is configurable to the surfaces and boundaries established by intermediate-level vision.
