Semantic processing from parafoveal words is an elusive phenomenon in alphabetic languages, but it has been demonstrated only for a restricted set of noncompound Chinese characters. Using the gaze-contingent boundary paradigm, this experiment examined whether parafoveal lexical and sublexical semantic information was extracted from compound preview characters. Results generalized parafoveal semantic processing to this representative set of Chinese characters and extended the parafoveal processing to radical (sublexical) level semantic information extraction. Implications for notions of parafoveal information extraction during Chinese reading are discussed.  相似文献

The transtheoretical model proposes that behavior change is experienced as a series of stages. Interventions tailored to these stages are most likely to be effective in progressing people through the model's hypothesized behavior change continuum. In this study, a stage-tailored, 12-week, exercise behavior intervention based on the transtheoretical model was conducted among a sample of 150 Chinese youth with hearing loss. Participants were randomized into an intervention or control group with all the core transtheoretical model constructs assessed pre- and post-intervention. Participants in the intervention group showed greater advances in their stage of exercise behavior change, decisional balance, and processes of change use compared to those in the control group. The intervention, however, was insufficient for increasing participants' self-efficacy for exercise behavior. The findings partially support the utility of the theory-based intervention for improving the exercise behavior of Chinese youth with hearing loss, while simultaneously helping to identify areas in need of improvement for future applications.  相似文献

The circular movement of migrants between their homelands and adopted countries has problematized the previous linear understanding of return migration. However, the concept of circular migration tends to apply to migrants whose movement is enabled by their extensive pre-migration connections with their homelands. In this paper, we report findings of a study on a group of new-generation Chinese–Canadian youth working in Hong Kong. Although, like many return migrants, this group of young people had economic reasons for moving to Hong Kong (their parents' homeland), they do not position themselves as return migrants. Instead, they have kept a strong Canadian identity by maintaining unique friendship circles and perceiving Canada as a home to which they will one day return. We highlight in this paper some implications of their experiences for transnational migration studies.  相似文献

采用累积生态风险问卷、消极自我图式问卷、网络成瘾问卷以及学习倦怠问卷对湖南省4所高职院校的664名高职生进行调查,考察累积生态风险与高职生学习倦怠的关系以及消极自我图式、网络成瘾的中介作用。结果发现:(1)高职生累积生态风险、消极自我图式、网络成瘾和学习倦怠均呈显著正相关;(2)高职生累积生态风险对学习倦怠的直接效应和间接效应均显著。间接效应包括了三条路径:通过消极自我图式的中介作用、通过网络成瘾的中介作用以及通过消极自我图式和网络成瘾的链式中介作用。这一结论有助于理解累积生态风险对学习倦怠的作用机制,为降低高职生的学习倦怠提供参考建议。  相似文献

The effects of self–other decision-making on intertemporal choice have been revealed in many studies using a monetary outcome. However, the outcome of intertemporal choice is not restricted to money; time is also a scarce and nonrenewable resource outcome. Thus, we conducted a series of experiments to address the effects of self–other decision-making on time-based intertemporal choice, a type of intertemporal choice that uses time as an outcome. Over the course of three experiments, differences in self–other decision-making were evidenced. Participants who made decisions for others were more likely to prefer the smaller but sooner (SS) option over the larger but later (LL) option and considered the gain of the SS option to be significantly greater than that of the LL option. Participants who made decisions for themselves were likely to prefer the LL option over the SS option. However, they considered the gains of the LL and the SS option to be indifferent. Changing the role of decision-making could affect the ability of individuals to consider the future consequences of their decisions. The effects of self–other decision-making on time-based intertemporal choice could be explained by the accounts of economic reasoning and construal level theory. The findings indicated that the effects of self–other decision-making on time-based intertemporal choice, which could be generated simply by rewording questions, can help individuals make optimal long-term choices without the need for increased control.  相似文献

职业乐观是影响个体职业适应的重要因素之一。尽管以往文献大多认为职业乐观是有利的,然而职业乐观的个体也会出现求职行为,导致对现有工作的专注程度降低的负面影响。为了探讨职业乐观的双刃剑效应及其边界条件,通过2个时间点问卷调查法对581名企业员工进行调查,结果发现:(1)职业乐观对求职行为和组织承诺均有正向影响;(2)易变职业生涯定向在职业乐观对求职行为影响中起中介作用,工作归属感在职业乐观对组织承诺影响中起中介作用;(3)心理授权在职业乐观对易变职业生涯定向的影响中起负向调节作用,在职业乐观对工作归属感的影响中起正向调节作用。  相似文献

抑郁焦虑与心血管疾病的关系最能体现身与心两者相互影响、不可分割的特点。但临床上,心血管疾病患者抑郁焦虑的诊疗率不足1%。这说明现有的诊疗理念和方式没有将心血管疾病和精神障碍联系起来,给患者全面全程的干预和管理。这样的缺陷不仅增加患者的痛苦和功能障碍,也增加心血管疾病的发病率和病死率,还增加患者及社会的医疗负担。本文结合临床经验,从心身一体的诊疗理念,谈谈抑郁焦虑与心血管疾病。  相似文献

The aim of this study was to determine the effects of psychological interventions (e.g. cognitive restructuring, relaxation) on physiological and psychological health in osteoarthritis patients. A systematic literature search was done using PubMed, Embase, PsycINFO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database through November 2016. Studies were included if they used a randomized controlled trial designed to explore the effects of psychological interventions in osteoarthritis patients. Two independent authors assessed the methodological quality of the trials using criteria outlined by Jadad et al. Meta-analysis was done with the Revman5.0. Twelve randomized controlled trials, including 1307 osteoarthritis patients, met the study inclusion criteria. Meta-analysis showed that psychological interventions could reduce the levels of pain [standard mean difference (SMD) ?0.28, 95% CI ?0.48, ?0.08, P-value 0.005)] and fatigue (SMD ?0.18, 95% CI ?0.34, ?0.01, P-value 0.04). In addition, psychological interventions significantly improved osteoarthritis patients’ self-efficacy (SMD 0.58, 95% CI 0.40, 0.75, P-value 0.00) and pain coping (MD 1.64, 95% CI 0.03, 3.25, P-value 0.05). Although the effects on physical function, anxiety, depression, psychological disability were in the expected direction, they were not statistically significant. In conclusion, the role of psychological interventions in the management of osteoarthritis remains equivocal. Some encouraging results were seen with regard to pain, pain coping, self-efficacy, and fatigue. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.  相似文献

Humans exhibit a remarkable ability to discriminate variations in object volume based on natural haptic perception. The discrimination thresholds for the haptic volume perception of the whole hand are well known, but the discrimination thresholds for haptic volume perception of fingers and phalanges are still unknown. In the present study, two psychophysical experiments were performed to investigate haptic volume perception in various fingers and phalanges. The configurations of both experiments were completely dependent on haptic volume perception from the fingers and phalanges. The participants were asked to blindly discriminate the volume variation of regular solid objects in a random order by using the distal phalanx, medial phalanx, and proximal phalanx of their index finger, middle finger, ring finger, and little finger. The discrimination threshold of haptic volume perception gradually decreases from the little finger to the index finger as well as from the proximal phalanx to the distal phalanx. Overall, both the shape of the target and the part of the finger in contact with the target significantly influence the precision of haptic perception of volume. This substantial data set provides detailed and compelling perspectives on the haptic system, including for discrimination of the spatial size of objects and for performing more general perceptual processes.  相似文献
