计算机化分类测验(Computerized Classification Testing, CCT)能够高效地对被试进行分类, 已广泛应用于合格性测验及临床心理学中。作为CCT的重要组成部分, 终止规则决定测验何时停止以及将被试最终划分到何种类别, 因此直接影响测验效率及分类准确率。已有的三大类终止规则(似然比规则、贝叶斯决策理论规则及置信区间规则)的核心思想分别为构造假设检验、设计损失函数和比较置信区间相对位置。同时, 在不同测验情境下, CCT的终止规则发展出不同的具体形式。未来研究可以继续开发贝叶斯规则、考虑多维多类别情境以及结合作答时间和机器学习算法。针对测验实际需求, 三类终止规则在合格性测验上均有应用潜力, 而临床问卷则倾向应用贝叶斯规则。  相似文献

It has become increasingly common for young children to be taken care of by multiple caregivers in China after the socio-economic reforms. Complex migration patterns and high female labour force participation have led to children receiving care from various individuals in different contexts. However, little is known about how childcare arrangements are associated with child health well-being. This study examines various early childhood caregivers and their influences on children’s physical health in China. Using data from the China Health and Nutrition Survey (CHNS 1991–2011) with 3,470 children aged 2 to 6, we first identified different types of childcare arrangements in and outside of the household based on who provides the care, where they provide the care, and the intensity of the care. Then we examined the relationship between various childcare arrangements and health outcomes for children. Overall, household members undertook early childhood care tasks in China, with an increase in grandparents as primary caregivers between 1991 and 2011. The proportion of children receiving formal childcare fluctuated around 20% during this period. The findings suggest that: 1) primary caregiver in the household other than parents is not associated with undesirable physical health outcomes; 2) formal childcare outside the household is associated with higher height and lower BMI scores; 3) primary caregivers in the household, particular grandparents, moderate the association between childcare arrangements outside the household and children’s health outcomes. It yields an implication that early childhood care policies incorporating multiple caregivers would benefit children’s well-being in China.

焦虑抑郁广泛存在于各种心血管疾病中已成共识。心律失常患者合并心理问题在临床上十分常见,焦虑抑郁导致的自主神经对心脏的调节失衡会进一步促使心律失常的发生与发展。对于非器质性心脏病,β受体阻滞剂与抗焦虑药物合用有很好的疗效;器质性心脏病患者并发心律失常时患者的焦虑抑郁会进一步加重,甚至导致恶性室性心律失常的发生,增加器质性心脏病患者的病死率;心律失常介入治疗引起的焦虑抑郁更为常见。临床上对焦虑抑郁症状要有充分的重视,积极识别并诊断,以期进一步提高心律失常患者的生活质量,减少病死率。  相似文献

近年来,乳腺癌的发病率不断上升,乳腺癌已逐渐成为危害女性健康的首位恶性肿瘤。手术给患者的身心带来很大伤害,但研究者发现,在与乳腺癌这一疾病做斗争的过程中患者会产生一种正向的心理变化,这就是积极心理学领域研究的创伤后成长。本文从创伤后成长内涵、国内外研究现状、测量工具、影响因素、干预方法等几方面对乳腺癌创伤后成长研究现状进行文献综述,为乳腺癌患者心理护理提供依据。  相似文献

个性化契约作为组织中一种非标准化的工作安排,以往研究较多关注其对契约获得者的积极效应,相对忽视了对未获得者的消极影响。鉴于此,本研究基于公平理论,探讨了同事个性化契约对员工工作退缩行为的影响及其内部机理。结果发现:同事个性化契约会引发员工的工作退缩行为,员工的心理契约违背在此过程中起部分中介作用;此外,员工与组织间较高的社会交换关系会削弱同事个性化契约对员工心理契约违背的正向影响。  相似文献

做出选择与坚持选择是决策活动的两个重要阶段。跨期选择源于经济学领域对成人对发生在不同时间点的结果"做出选择"过程的研究;延迟满足则源于心理学领域对儿童为获得未来较大收益而抵制当前诱惑的"坚持选择"过程的研究。二者均致力于研究与时间相关的决策活动,从不同视角关注个体的冲动性与自我控制,但鲜见学者对二者异同的系统比较。本文着重从研究方法、认知机制与神经基础入手探讨了二者的异同,冀为两个研究领域协同发展、共同促进人类远见的培养与实践提供科学的理论支持。  相似文献

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.  相似文献

To enhance the predictive validity of self-report personality measures, 2 distinct ways of increasing specificity of personality measures have been proposed in the literature—contextual specificity (i.e., providing a contextual referent) and content specificity (i.e., focusing on more specific constructs such as the Big Five facets). This study extends this line of research by examining whether there is an optimal way to configure, align, or integrate contextual and content specificity using measures of conscientiousness to predict college student success. A sample of 478 undergraduate students completed 4 measures of conscientiousness that varied in the level of content and contextual specificity. These forms of specificity were crossed to yield 4 distinct measures of conscientiousness. We then evaluated and compared the relative importance and the incremental importance of these different measures in the prediction of academic success. Superior predictive validity was found for both contextualized and facet measures of conscientiousness compared to a measure of global conscientiousness in predicting grade-point average and a broader behavioral criterion of student performance. When contextual and content specificity approaches were compared and combined, we observed the strongest predictive validity when the level of specificity is appropriately matched between predictor and criterion.  相似文献
