Prior research developed the Attention-Related Driving Errors Scale (ARDES), a 19-item questionnaire aimed at evaluating the drivers’ predisposition to attentional error, and also provided validity evidence of ARDES measures across two countries: Argentina and Spain. In the current work we adapt the Spanish version of the ARDES to the English language and the culture, traffic regulations and driving habits of the UK, and then provide new evidence of the cross-cultural equivalence of the scale. First, an improved forward and backward translation design was used to translate the Spanish ARDES into English. A committee-approach review process was also performed during the translation phase to guarantee that the English ARDES was the most appropriate to reflect the language, culture, traffic regulations and driving habits of the UK. Second, the adapted questionnaire was tested on 301 British drivers to inspect its psychometric properties and study the relationships between the ARDES-UK and different socio-demographic variables. In agreement with the previous literature, the results of the factor analysis confirmed a single factor and accounting for 33.84% of the variance. Cronbach’s alpha was equal to .89. The observed pattern of relationships of the scores and the different socio-demographic variables was consistent with previous evidence and support the validity of the adapted questionnaire. For example, the ARDES-UK scores were significantly different between drivers reporting and not reporting traffic accidents with material damage. To conclude with, the translation design and the resulting psychometric suggest the validity of ARDES-UK measures for evaluating the British drivers’ predisposition to attentional error. In addition, the evidence in the current work supports the hypothesis of the cross-cultural stability of the scale across Spain and the UK. 相似文献

中医专科是祖国传统医学的重要组成部分,是中医的精华和灵魂,对中医的延传和发展意义重大。为了解区级中医院中医专科的发展现状,笔者对广州各区级中医院进行实地问卷调查。结果显示区级中医院中医专科设置较单一,各专科在医疗方面的优势地位不突出,学科队伍建设欠完善,部分专科的科研水平亟待提升。 相似文献

以既可用作名词,又可用作动词的汉语双音节兼类词为材料,采用移动窗口范式,考察了汉语句子中名词倾向性高和低两类兼类词句法分析的详细历程。结果发现,两类兼类词与各自的控制词之间,均未出现阅读时间上的显著差异,因此并不支持延迟模型所提出的兼类词句法角色延迟指派的观点。实验还发现,名词倾向性高的兼类词引起了更大的加工困难。此外,即便是名词倾向性低的兼类词,被试也仍为其指派名词的句法角色。花园路径模型和制约满意理论均不能单独和完整解释上述发现。文章指出,实验结果支持一种既不同于花园路径模型,又不同于制约满意理论的权变的理论。阅读中遇到兼类词时,读者能立即为其指派句法角色。这种指派过程既可以利用概率制约信息,也可以在句法分析原则指导下进行。句法分析原则是否起作用,取决于概率制约信息的制约强度 相似文献

话语参照语境条件下汉语歧义短语的加工 总被引:12,自引:1,他引:11
采用移动窗口和眼动记录两种范式 ,以符合“VP +N1+的 +N2”格式的均衡型和述宾型两类汉语歧义短语为背景 ,在两个实验中 ,考察了话语参照语境影响歧义短语句法分析的机制以及时间进程。结果发现 ,在早于解歧区 1的区段上就开始出现话语语境效应。这些发现表明话语参照语境可以通过概念期望机制起作用 ,而并非仅仅通过参照前提机制起作用。此外 ,实验还证明了话语参照语境在句子加工早期的作用。这一结果为句法歧义消解的参照理论和基于制约的模型提供了证据 ,而对宣称最初的句法分析独立于话语语境的花园路径模型 ,提出了质疑 相似文献

本研究探讨了汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响.实验结果表明逆意排列的汉字词处于不同方位(正位、左右倾斜90°、倒位),对汉字词的念读速度产生明显影响.汉字词处于正位时,念读速度最快;其次是处于左斜与右斜90°;对汉字词的念读速度最慢而准确性最低是处于倒位时(汉字词颠倒).汉字词无论是顺意排列或是逆意排列,正位结果均明显优于倒位结果;但汉字词在倒位顺意排列条件下,结果优于正位逆意排列的结果,这表明,字词间的意义联系的作用大于字词方位的作用. 相似文献

本研究根据汉字形义系联的特性设计字形系联识字法,并且进行教学实验。研究发现采用字形系联识字法较诸传统识字法,无论在形音义的辨认正确率都有显著差异.而且时问越久,差异越大。字形系联识字法的形音义相关系数很高,但教材编排的次序对辨识正确率无显著差异。 相似文献

This experiment evaluated the effects of training tutors to use an instructional package to teach pronunciation and translation of the Chinese language. Tutors' correct use of the package increased from 68% of trials to 92% after training, and student correct pronunciation increased from 45% to 90%, with similar effects for translation. Continued use of the package, high social validity, and extended follow-up suggest that use of the package may be sustainable. 相似文献

Addressing the unique needs of youth transitioning to adulthood has long been viewed as a priority in implementation of systems of care (SOCs) and wraparound. Developmental research and "practice-based evidence" suggest that there are differences between transitioning youth and their younger peers in family environment and wraparound team processes. Although these differences are thought to have significant implications for wraparound practice, few studies have examined them empirically. The present research involves two studies examining differences across several age cohorts (i.e., 10–12, 13, 14, 15, 16–17 year-olds) ranging from early adolescent to transitioning youth in: (1) caregiver perceptions of role-related strain and family environment quality, and (2) facilitator, caregiver, and youth perceptions of wraparound processes. In Study #1, older age was associated with higher levels of caregiver strain. In Study #2, age was associated with differences between youth and other team members' perceptions of wraparound processes, such that older youth perceived teams as less cohesive than others on their teams. These findings suggest that transitioning youth and their families merit special consideration in wraparound implementation and underscore the importance of considering the perceptions of transitioning youth in system change and practice improvement efforts (192 words). 相似文献

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects. 相似文献
