探究正念训练对康复期精神分裂症患者正念觉知水平和抑制控制能力的影响。选取54名康复期精神分裂症住院患者随机分为正念组和对照组。对照组予以常规康复治疗,正念组在常规康复治疗基础上进行8周正念训练。结果发现:(1)在正念觉知方面,正念组后测得分显著高于前测,对照组前后测得分无显著差异;正念组后测得分显著高于对照组。(2)在抑制控制方面,正念组后测Stroop任务反应时显著低于前测,对照组前后测反应时无显著差异;正念组后测反应时显著低于对照组。结果表明,正念训练有助于提高康复期精神分裂症患者正念觉知水平和改善其抑制控制能力。 相似文献

Booster interventions have been presumed to be important methods for maintaining the effects of evidence-based programs for children with behavioral problems, but there has been remarkably little empirical attention to this assumption. The present study examines the effect of a child-oriented booster preventive intervention with children who had previously received an abbreviated version (24 child sessions, 10 parent sessions) of the Coping Power targeted prevention program. Two hundred and forty-one children (152 boys, 89 girls) were screened as having moderate to high levels of aggressive behavior in 4th grade, then half were randomly assigned to receive the abbreviated Coping Power program in 5th grade, and half of the preventive intervention children were then randomly assigned to a Booster condition in 6th grade. The Booster sessions consisted of brief monthly individual contacts, and were primarily with the children. Five assessments across 4 years were collected from teachers, providing a three-year follow-up for all children who participated in the project. Results indicated that the abbreviated Coping Power program (one-third shorter than the full intervention) had long-term effects in reducing children’s externalizing problem behaviors, proactive and reactive aggression, impulsivity traits and callous-unemotional traits. The Booster intervention did not augment these prevention effects. These findings indicate that a briefer and more readily disseminated form of an evidence-based targeted preventive intervention was effective. The findings have potential implications for policy and guidelines about possible intervention length and booster interventions. 相似文献

It is shown that the compressive plasticity of a metallic glass, namely Zr52.5Ni14.6Al10Cu17.9Ti5, can be improved by the introduction of two symmetrical notches. The enhanced plasticity may be ascribed to a blocking effect of the propagation of shear bands caused by large stress gradients around the notches. In contrast to ceramic specimens with similar notches, the plasticity enhancement of metallic glass induced by notches can provide a new approach to understanding its unique mechanism of deformation. 相似文献

In this pilot study, we examined the relationship between health factors, sociodemographic factors, and body mass index (BMI)
across two generations (n = 41 parent-child pairs). Generation 1 study variables included parent- and family-focused characteristics and health variables,
the Generation 2 variables included child demographic factors, and the outcome variable was youths’ physical health (operationalized
as BMI). Regression models revealed that Generation 1 variables, taken together, accounted for 26% of the variance in youth
BMI. However, only the parent’s mental health symptoms (i.e., depression symptoms) made a unique contribution to the variance
in youth BMI. Logistic regression analysis revealed that the youths’ race and age—but no other demographic factor—were significantly
related to youth BMI-for-age. Our findings suggest that youth race, age, and parent mental health are each associated with
youth physical health (i.e., BMI), confirming previous study findings that parental factors and demographic factors should
be considered when exploring youth health outcomes. 相似文献

Six experiments investigated the effect of the promotion criterion in simulated academic promotion decisions. In total, 547 undergraduate students and 33 university faculty members rated a promotion application, and some also indicated their decisions to support or to reject it. Performance ratings were reliably affected by the criterion, with a high criterion resulting in higher ratings than a low criterion, and this criterion effect was found regardless of the evaluator's expertise, whether he or she took the role of an independent assessor or the line manager to the applicant, or whether the criterion was provided by the experimenter or randomly generated by the participant. The criterion also affected the level of support for a candidate when the position applied for was perceived to be extremely competitive, or when a lesser position was considered at a later time. These results provide evidence that the use of a criterion, a fairly common practice in decision‐making processes, may bias performance evaluations, which in turn may have ripple effects that affect the outcome of a chain of events. Our results also shed light on the possible mechanisms that underlie the rating biases in performance appraisal. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

视觉空间注意是人的一种基本认知功能,对老年人的生活有重要影响。N2pc作为一种与注意选择相关的ERP成分,可以反映注意资源在空间上的分配,是研究视觉空间注意的一个良好指标。本文对此前基于N2pc成分的注意功能老化研究进行了综述。前人研究主要采用视觉搜索范式与空间线索范式。采用视觉搜索范式的研究发现,当目标周围有干扰子时,目标诱发的N2pc在老年人中振幅减小,潜伏期延迟,同时在行为上老年人与年轻人相比,正确率更低,反应时更长; 当目标周围无干扰子时,目标诱发的N2pc振幅老年人与年轻人相当或比年轻人更大,老年人的正确率与年轻人无显著差异。采用空间线索范式的研究发现,与目标无相同特征的线索奇异子(singleton cue)不会诱发N2pc,与目标有相同特征的线索奇异子诱发的N2pc未表现出年龄差异,差异体现在一种反映抑制的ERP成分—Pd上(年轻人有Pd而老年人没有),此时老年人在行为上表现出比年轻人更强的空间线索效应。这些研究共同说明,视觉空间注意功能的老化是一个复杂的过程,涉及到搜索目标时注意分配速度的减慢,对干扰子抑制能力的下降以及基于特征的注意捕获能力的良好保持。 相似文献

The "distractor eccentricity effect" refers to the finding of reduced interference from an incompatible distractor at a central relative to a peripheral location (Chen, 2008). The present study examines the mechanism that underlies the distractor eccentricity effect, and relates it to the inattentional blindness explored by Mack and Rock (1998), which was also more marked at a foveal than at a parafoveal location. The results suggest that these two visual phenomena may reflect the same underlying mechanism--a gradient of increasing attentional suppression from the periphery to the center. 相似文献

本实验采用2被试组别(MCI组、正常老年组) × 3进行中任务变化(无变化、顺序变化、随机变化)被试间设计探究进行中任务变化对轻度认知功能障碍者基于事件前瞻记忆的影响。结果表明:(1)轻度认知功能障碍者的前瞻记忆成绩显著低于正常老年人的前瞻记忆成绩; (2)进行中任务变化对两组被试前瞻记忆和进行中任务的反应时影响存在显著差异。进行中任务变化越大, 轻度认知功能障碍者完成前瞻记忆和进行中任务的反应速度越慢; 而正常老年被试则不受影响。研究支持前瞻记忆策略加工的理论观点, 认为执行功能损伤可能是导致轻度认知功能障碍者前瞻记忆失败的主要原因。 相似文献
