Self-rated general health has been used widely in health surveys as a single-item measurement of health-rated quality of life.
Heterogeneity in self-evaluation of health has been well documented, yet the causes of this heterogeneity are poorly understood.
This study evaluated the moderating effects of age, aging, gender, race, education and income on the relationship between
physical functioning and self-rated general health using social comparison theory as a guiding framework. A longitudinal mixed-effects
regression model was used to analyze a cohort enrolled into the Health and Retirement Study in 1993 that was interviewed at
baseline and during four subsequent waves. The results revealed that the association between physical functioning and self-rated
general health is weaker among subgroups that tend to have lower health status; i.e., older individuals, non-Caucasians and
less educated individuals. These findings suggest the usefulness of social comparison theory in explaining self-rated general
health and provide the basis for future research. 相似文献

Attention deficit hyperactivity disorder (ADHD) persists frequently into adulthood. The decomposition of endophenotypes by means of experimental neuro-cognitive assessment has the potential to improve diagnostic assessment, evaluation of treatment response, and disentanglement of genetic and environmental influences. We assessed four parameters of attentional capacity and selectivity derived from simple psychophysical tasks (verbal report of briefly presented letter displays) and based on a "theory of visual attention." These parameters are mathematically independent, quantitative measures, and previous studies have shown that they are highly sensitive for subtle attention deficits. Potential reductions of attentional capacity, that is, of perceptual processing speed and working memory storage capacity, were assessed with a whole report paradigm. Furthermore, possible pathologies of attentional selectivity, that is, selection of task-relevant information and bias in the spatial distribution of attention, were measured with a partial report paradigm. A group of 30 unmedicated adult ADHD patients and a group of 30 demographically matched healthy controls were tested. ADHD patients showed significant reductions of working memory storage capacity of a moderate to large effect size. Perceptual processing speed, task-based, and spatial selection were unaffected. The results imply a working memory deficit as an important source of behavioral impairments. The theory of visual attention parameter working memory storage capacity might constitute a quantifiable and testable endophenotype of ADHD. 相似文献

We assessed the differences in psychological distress and delinquent participation between singleton and non-singleton Chinese
adolescents and the extent to which parental responsiveness (mother’s vs. father’s) might account for such differences. Using
survey reports of 1,924 7th and 8th graders from three middle schools in the outskirts of Fuzhou, China, we observed small
but significant differences between singleton and non-singleton adolescents. Singletons reported lower levels of psychological
distress and delinquent participation than non-singleton adolescents. Furthermore, singletons received higher levels of parental
responsiveness, which was inversely related to psychological distress and delinquent participation, respectively. The difference
in psychological distress between singletons and non-singletons was completely mediated by both maternal and paternal responsiveness.
Paternal responsiveness alone fully mediated the difference in delinquent participation between singleton and non-singleton
adolescents. We discussed these results in light of both theoretical literature and empirical implications. 相似文献

In this study, we investigated the immediate and persisting effects of object location changes on gaze control during scene viewing. Participants repeatedly inspected a randomized set of naturalistic scenes for later questioning. On the seventh presentation, an object was shown at a new location, whereas the change was reversed for all subsequent presentations of the scene. We tested whether deviations from stored scene representations would modify eye movements to the changed regions and whether these effects would persist. We found that changed objects were looked at longer and more often, regardless of change reportability. These effects were most pronounced immediately after the change occurred and quickly leveled off once a scene remained unchanged. However, participants continued to perform short validation checks to changed scene regions, which implies a persistent modulation of eye movement control beyond the occurrence of object location changes. 相似文献

一种对动物学习记忆能力突变筛查的新途 总被引:1,自引:0,他引:1

本文详细描述了一种全自动化的行为检测方案。在自然饲养环境/检测环境(24/7)中, 我们测量了小鼠针对两个给食器中获得食物的比例与它们在相应给食器停留时长的比例进行匹配的精确性与准确性。该方案是对传统条件性习得 (trials-to-acquisition) 行为测验设备的改进, 可以检测动物时间间隔能力的精确性与准确性, 对定时目标选择的相关概率的效果, 以及记忆一天中从不同给食器中获得食物次数的精确性与准确性。该压缩系统避免了在整个实验过程中对小鼠的持握操作, 可忽略实验者/技术员的实验操作时间, 而且可以递送小鼠置入实验环境后, 7~9个实验日中全部3组实验流程产生的大量结果。其中, 第一个实验流程为单个24小时周期内完成的时间匹配能力的筛查, 它对动物的时间、空间估计能力的记忆机制进行精确检测。因此, 该系统允许在有限的实验空间、较短的实验周期内, 对大量的实验小鼠进行有可能存在的学习记忆能力缺陷进行大规模筛查。此外, 该系统运行所依赖的软件可以在公共开放平台获得。 相似文献

CSR"品牌":以企业社会责任提升国家形象 总被引:1,自引:0,他引:1
消费者对别国的国家形象是通过食品、艺术、旅游等多种接触渠道形成的,其中一种体验会引发并上升为整个国家形象,即“光环效应”。申言之,消费者对其他国家的形象是通过消费者对该国产品的体验间接培育的,而消费者对其他国家某种产品的正、负面体验,将直接影响对该国其它产品的相应看法,即“连带效应”。据此,本文推论,民众可以通过企业社会责任的“光环效应”认知一个国家,进而依据“连带效应”形成对一国企业产品社会责任的总体印象。韩国在华中小型企业社会责任的不良纪录,很可能导致对韩国国家形象的负面看法。特有的集体行动逻辑阻碍了韩国在华中小型企业及时采取反应,其结果又反过来伤害其自身。 相似文献

Two studies assessed the relationships between perceived similarity to the college student prototype and academic outcomes. In Study 1, students' similarity to the prototypical good student and their levels of depressed mood were assessed. A year later, students high in depressed mood who did not see themselves as similar to the good student prototype did worse academically. In Study 2, students' perceived favorability and similarity to the prototypical student at their university were assessed along with their levels of neuroticism. Enrollment at their university was then tracked for 5 semesters. Students high in neuroticism who perceived the typical student as both favorable and dissimilar to themselves were less likely to stay enrolled. These findings highlight the importance of perceived dissimilarity in prototype perception, particularly among those high in negative affect. 相似文献
