In China, there is an increasing demand for preschool children with autism spectrum disorder (ASD) enrolled in general education to learn English vocabulary. The purpose of this study was to evaluate the effect of foreign mand training in English on the acquisition of mand responses, and the emergence of tact and listener responses for three Chinese-speaking preschool children (boys; 4–5 years of age) with ASD. Echoic-to-mand training was implemented to teach mands in English. The study employed a concurrent multiple-probe design across behaviors. The results of the study indicated that the training was effective in the acquisition of mand responses. Moreover, untaught tacts and listener responses for the same vocabulary emerged without explicit training. Implications for small-group mand training in foreign language acquisition were discussed.  相似文献

Many studies have demonstrated the beneficial effects of parental attachment on adolescent development. However, few studies have specifically investigated the different effects of paternal attachment and maternal attachment on adolescent development. The current study examined the different effects of paternal attachment and maternal attachment on adolescent psychological health (e.g., self-esteem, depression, life-satisfaction), and the moderating roles of gender, age, and one-child status. Participants were 1506 secondary school students (50.2 % male, grades 7–12) from six regions of China. Results suggested that paternal attachment had stronger effects on adolescents’ depressive symptoms than did maternal attachment after controlling for all covariates (e.g., family setting, gender, grade, one-child status, father’s and mother’s education levels). Moreover, multi-group analysis indicated that the stronger impact of paternal attachment on depressive symptoms in comparison to maternal attachment was only evident in high school boys and only children. This study demonstrated the important role of father–adolescent attachment in adolescent psychological health. Future research, clinical implications, and limitations of the present study are discussed.  相似文献

The association between psychological factors and smoking cessation is complicated and inconsistent in published researches, and the joint effect of psychological factors on smoking cessation is unclear. This study explored how psychological factors jointly affect the success of smoking cessation using a Bayesian network approach. A community-based case control study was designed with 642 adult male successful smoking quitters as the cases, and 700 adult male failed smoking quitters as the controls. General self-efficacy (GSE), trait coping style (positive-trait coping style (PTCS) and negative-trait coping style (NTCS)) and self-rating anxiety (SA) were evaluated by GSE Scale, Trait Coping Style Questionnaire and SA Scale, respectively. Bayesian network was applied to evaluate the relationship between psychological factors and successful smoking cessation. The local conditional probability table of smoking cessation indicated that different joint conditions of psychological factors led to different outcomes for smoking cessation. Among smokers with high PTCS, high NTCS and low SA, only 36.40% successfully quitted smoking. However, among smokers with low pack-years of smoking, high GSE, high PTCS and high SA, 63.64% successfully quitted smoking. Our study indicates psychological factors jointly influence smoking cessation outcome. According to different joint situations, different solutions should be developed to control tobacco in practical intervention.  相似文献

The present studies examined the nature of kinematic interlimb interference during bilateral elbow movements of 1:1, 2:1 and 3:1 frequency ratios and the manner in which subjects cope with coordination bias. Analysis of movement trajectories in the first experiment indicated progressively greater angular velocity assimilation across 2:1 and 3:1 conditions. The desired temporal relationship was maintained by slowing or pausing the low-frequency movement at peak extension while the high-frequency arm produced intervening cycles. An increase in amplitude was also evident for concurrent, homologous cycles. Movement smoothness was emphasized and additional practice was provided in a second experiment. This resulted in dissociated peak angular velocity between limbs and eliminated hesitations and amplitude effects. Bias was still evident, however, as an intermittent approach toward a 1:1 ratio within each cycle. This systematic tendency was somewhat greater at the lower of two absolute frequency combinations but was not influenced by the role of each arm in producing the higher or lower frequency movement. The findings from the first experiment suggest that subjects initially accommodate interlimb kinematic assimilation, while producing the intended timing ratio, by intermittently slowing or pausing the lower-frequency movement. This attenuates the need for bilaterally-disparate movement parameters and provides additional time for organizing residual kinematic differences, perhaps reducing transient coupling. Evidence from the second experiment indicates that subtle relative motion preferences are still evident following sufficient practice to perform the movements smoothly. The within-cycle locations of the points of greatest interlimb bias for the 2:1 rhythms were positively displaced from those previously observed for 1:1 oscillations. The persistent coordination tendencies noted in both experiments perhaps reflect an assimilation/compensation cycle and constitute one potential source of the systematic error that often emerges during the acquisition of complex skills.  相似文献

通过综合分析风险决策任务内部表征的性质、特点、类型、形成规则及其重要的相关研究,认为风险决策的关键是正确合理的内部表征;决策者关于风险决策任务的内部表征、自我表征、情境表征与对手表征共同构成的决策表征系统及其有关的知识结构是决策空间的核心部分,应当成为风险决策研究的重要课题。  相似文献

主流跨期决策模型认为, 跨期决策存在一个时间折扣过程。时间折扣是指人们会根据将来获益或损失的延迟时间对其效用进行折扣, 折扣后的效用小于原来的效用, 而负折扣现象违背了时间折扣过程。负折扣现象出现在金钱、非金钱的获益与损失领域, 其可能的解释机制为预期情绪。目前关于负折扣现象的研究, 较少验证其影响机制, 未来的研究可以结合眼动追踪和fMRI技术探讨其机制, 并丰富对负折扣现象的影响因素研究。  相似文献

进展期胃癌术后生存质量影响因素探讨   总被引:4,自引:1,他引:3  
胃癌是我国发病率和病死率较高的恶性肿瘤,且住院病例90%以上为中晚期。因此预后不佳。近年来在进展期胃癌诊断和治疗方面有较大进展,尤其是人们对术后生存质量的重视。本文初步探讨了进展期胃癌术后生存质量的影响因素:如患者一般状况、手术方式、术后辅助放化疗和中医药治疗等。  相似文献

Judging Gadamer’s theoretical stance is a complicated matter, and his ontological hermeneutics is usually regarded as a text-centered theory of understanding. Through an analysis of the phenomenological premises from which his theories take off, however, we can clearly see his reader-centric stance. On the basis of this stance some cease to seek for the original intention of the author or the original meaning of the text, which ineluctably leads to the ignorance of an understanding methodology. As far as people’s intentional understanding is concerned, however, the important as well as essential task is still that of striving for a certain kind of understanding that is relatively correct, with universally effective methodology as its necessary prerequisite. What is more, herein lies the significance of the epistemology of hermeneutics. This article aims to re-insert a sense of methodology after hermeneutics went through a period of ontological reflection, and hence clarify that it is of necessity that hermeneutics resumes its text-centric methodological stance. __________ Translated by Zhang Lin from Zhongguo shehui kexue 中国社会科学 (Social Sciences in China), 2008, (2): 42–53  相似文献
