通过追溯欧美和中国结核病疗养院产生、发展直至消亡的历史来探寻曾经风行百年的“疗养院疗法”.经考证,正是链霉素、异烟肼等杀菌药物的发明使得结核病疗养院成为历史的陈迹.结核病疗养院之兴衰表明:新的、疗效显著的治疗手段出现之后,旧的疗效差的疗法因此被淘汰,基于旧疗法的治疗机构亦随之过时. 相似文献

已有研究表明,上行比较对高自尊个体产生积极效应。然而鉴于高自尊包括安全性高自尊和防御性高自尊,有必要在上行比较影响不同任务领域内的行为表现这一观点的基础上探讨高自尊的不同类型对上行比较与行为表现之间关系的影响。两个实验均采用高自尊类型、上行比较和任务领域一致性的2×2×2混合因素设计,不同之处在于其分别采用创造性测验和非创造性的语词测验作为不同领域任务。结果表明,防御性高自尊个体没有像安全性高自尊个体那样采取领域转换策略来修复自我关注,由上行比较所引起的领域转换只对安全性高自尊个体产生积极影响。 相似文献

This article introduces a simple survey method to distinguish between two types of variables that affect happiness—type A, which exerts an absolute effect on happiness, and type B, which affects happiness only through social context. The authors validate the method by comparing its findings with the findings of a theoretically superior but less practical experimental method, and use the method to identify the AB nature of a variety of naturally-occurring variables among both college students and people with work experience. We conclude by discussing the limitation of this method as well as its potential to inform policymakers about where to invest resources in order to improve people’s happiness over time. 相似文献

Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased
risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated
how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are associated with early-onset substance
use, the role of persistent ADHD for the association, and to what extent the association is influenced by genetic and environmental
factors. Twins (1,480 pairs) in the Swedish Twin Study of Child and Adolescent Development were followed from childhood to
adolescence. ADHD symptoms were measured at age 8–9 and age 13–14 via parent-report, whereas substance use was assessed at
age 13–14 via self-report. Results revealed that hyperactive/impulsive symptoms predicted early-onset “sometimes” tobacco
use (adjusted odds ratios, 1.12, for one symptom count), controlling for inattentive symptoms and conduct problem behaviors.
There is no independent effect of inattentive symptoms on early-onset substance use. Children with persistent hyperactivity/impulsivity
(defined as scoring above the 75th percentile at both time points) had a pronounced risk of both early-onset tobacco and alcohol
use (adjusted odds ratios from 1.86 to 3.35, compared to the reference group). The associations between hyperactivity/impulsivity
and early-onset substance use were primarily influenced by genetic factors. Our results indicated that hyperactivity/impulsivity,
but not inattention, is an important early predictor for early-onset substance use, and a shared genetic susceptibility is
suggested to explain this association. 相似文献

如何削弱产品来源国效应*—— 产品信息呈现方式的影响研究 总被引:1,自引:0,他引:1
以元认知和双系统模式的心理学理论为背景, 研究了分析式系统对来源国效应的削弱, 检验了产品信息呈现方式对来源国效应的调节作用。三个研究说明, 分析式系统的启动可以有效削弱来源国效应; 特定的产品信息呈现方式所引起的消费者信息处理不流畅性感知会激发消费者的元认知困难, 从而使他们在产品评价过程中主要依赖分析式系统, 达到削弱来源国效应的目的; 并不是所有能引起信息处理不流畅性的产品信息呈现方式都能削弱来源国效应, 过于复杂的呈现方式由于给消费者带来过多认知负荷, 反而不能成功启动分析系统, 从而无法削弱产品来源国形象对消费者产品评价的影响。 相似文献

This study determined the working memory (WM) components (executive, phonological loop, and visual–spatial sketchpad) that best predicted mathematical word problem-solving accuracy of elementary school children in Grades 2, 3, and 4 (N = 310). A battery of tests was administered to assess problem-solving accuracy, problem-solving processes, WM, reading, and math calculation. Structural equation modeling analyses indicated that (a) all three WM components significantly predicted problem-solving accuracy, (b) reading skills and calculation proficiency mediated the predictive effects of the central executive system and the phonological loop on solution accuracy, and (c) academic mediators failed to moderate the relationship between the visual–spatial sketchpad and solution accuracy. The results support the notion that all components of WM play a major role in predicting problem-solving accuracy, but basic skills acquired in specific academic domains (reading and math) can compensate for some of the influence of WM on children’s mathematical word problem solving. 相似文献

This paper reports two studies: Study 1 aimed to evaluate respective modified versions of existing scales of psychological capital (PsyCap) and study engagement (SE), and to test the reciprocal relationship between PsyCap and SE; Study 2 aimed to test intrinsic motivation as a mediator between PsyCap and SE. A two-wave cross-lagged design was adopted in Study 1 with a matched sample of 103 students, with 4 months apart. With confirmatory factor analyses, the results supported the construct validity of a higher-order model of PsyCap (PsyCap overall) and of study engagement comprising dedication, absorption and vigor. Further, the reciprocal relationship between PsyCap and SE was demonstrated. Results of Study 2 among 100 university students showed that intrinsic motivation measured at time 2 was a significant mediator between time 1 PsyCap and time 2 SE. 相似文献

先前研究发现远距离规则能够被内隐地习得和迁移,表明内隐学习获得的知识是底层的抽象规则,那么这一抽象规则的习得和迁移是否会受到先前知识经验的限制?研究采用汉语声调的远距离水平映射规则为材料,通过创设不符合平仄知识经验的任意声调水平映射规则,在控制组块和重复结构等表面特征的条件下,探讨先前知识经验是否限制了远距离水平映射规则的内隐学习和迁移。结果发现相对于符合平仄知识经验的汉语声调水平映射规则,被试不能够内隐地习得和迁移任意声调的水平映射规则,表明先前知识经验在远距离水平映射规则内隐学习过程中发挥着重要作用。 相似文献

教师领导力是指教师在课堂内外带领同事提升专业技能,与其他教师和校长合作处理学校事务的一种专业特质。为探究教师教学自主权与教师领导力的关系,以及教师心理授权和教学自主性的中介作用,从而寻求提升教师领导力的路径,研究选取403名中小学教师进行问卷调查。结果发现:(1)教学自主权与教师领导力呈显著正相关,且前者对后者有显著直接效应;(2)教师心理授权和教学自主性分别在教学自主权与教师领导力间发挥部分中介作用;(3)教师心理授权和教学自主性在教学自主权对教师领导力间发挥部分链式中介作用,即教学自主权的提高会促进教师心理授权和教学自主性的提升,进而促进教师领导力的发展。 相似文献
