The representation of discourse in the two hemispheres: an individual differences investigation

Two experiments were conducted to investigate discourse representation in the two cerebral hemispheres as a function of reading skill. We used a lateralized visual-field procedure to compare left hemisphere (LH) and right hemisphere (RH) sensitivity to different discourse relations in readers with varying skill levels. In Experiment 1, we investigated two levels of discourse representation in memory: (a) the propositional representation and (b) the discourse model. We found that all readers were sensitive to propositional relations in the LH. In contrast, sensitivity to propositional relations in the RH increased as a function of reading skill. In addition, reading skill was positively related to topic relations in the LH, whereas it was negatively in the RH. In Experiment 2, we investigated propositional relations of different distances and again found that all readers were sensitive to propositional relations in the LH, whereas sensitivity to propositional relations in the RH was negatively related to reading skill. In general, reading skill appears to be associated with left-lateralized discourse representations.     

Children's perceptions and experiences of care giving: A focus group study

The stress of care giving for spouses and adult children has been extensively documented in the empirical literature. More recently attention has been paid to children's involvement in family care giving. Qualitative studies in the social welfare field have highlighted the social restrictions caring places upon children. There remains a need, however, to understand what children are thinking and feeling in an effort to cope with their care-giving demands. This study used a focus group methodology and individual interviews to explore the experiences of 17 young carers aged between 10 and 16. Thematic analysis was employed to identify themes relating to the nature of stressors, their appraisal of them, and the coping strategies they use to manage the task of caring.     

Promoting Generalization of Oral Reading Fluency: Providing Drill versus Practice Opportunities

Extensive evidence exists demonstrating the benefits of repeated readings (RR) interventions at increasing students’ fluency on intervention passages. Few studies however have examined the extent to which repeatedly reading one passage improves students’ reading fluency on similar passages. Using an alternating treatment design, we examined the extent to which two interventions resulted in improvements in students’ fluency on generalization passages. While both interventions incorporated RR, one intervention involved students reading one passage four times and the other involved students reading two similar passages each twice. Intervention effects were evaluated by having students read a generalization passage prior to and following intervention implementation. Results indicate that both interventions were effective in increasing students reading fluency on generalization passages. For 3 participants the RR intervention produced greater gains in fluency on the generalization passages, while data for the remaining 3 participants are inconclusive. Implications of these findings for practice and for better understanding application of the instructional hierarchy to the development of reading interventions are discussed.

Regulatory Focus Strategies Scale: A measure of individual differences in the endorsement of regulatory strategies

Regulatory focus theory proposes that people can have a promotion or a prevention focus when pursuing goals and choosing strategies. The Regulatory Focus Strategies Scale (RFSS), a scale that assesses the endorsement of promotion and prevention strategies for goal pursuit, is developed and validated in three studies. Exploratory and confirmatory factor analyses in Australia and Japan showed that promotion- and prevention-focused strategic endorsement formed two largely uncorrelated factors. The RFSS exhibits adequate reliability, and discriminant and convergent validity. A cross-cultural comparison showed that Australians were more promotion- but less prevention-focused than Japanese students. The RFSS provides an additional measure that is useful in future research on self-regulatory strategies.     

Career barriers and reading ability as correlates of career aspirations and expectations of parents and their children

Data were obtained from 176 Year 7 children (mean age = 12.2 years) on career status aspirations and expectations, career barriers, academic engagement, academic control beliefs, general ability and literacy; and from parents, mainly mothers, on aspirations, expectations and career barriers. Discrepancy scores between aspirations and expectations were calculated for both children and parents. Children differed from parents on career status aspirations and expectations; boys did not differ from girls, and parents did not differentiate between boys and girls. Parents’ and children’s aspirations were both associated with reading ability, although the association was weak for the children. Children’s expectations were associated with perceptions of career barriers, and a trend towards reading abilities, while parents’ expectations were associated with general ability and reading.     

Correlates of Canadian native children's reading performance: From cognitive styles to cognitive processes

Individual differences in reading and cognitive processing among a sample of generally poor readers were studied in order to answer two major questions: Do they have a specific cognitive style that favors global-simultaneous strategies and a weak sequential strategy? If they do not have a distinct cognitive style or strategy, but are merely poor in using sequential (Successive) strategies, then, would the same processes that influence reading performance in the general population determine their performance as well? A sample of 84 Canadian First Nations (FN) children were assessed in word and pseudoword reading, rapid naming speed, and ability to process information using the Planning, Attention, Successive, and Simultaneous (PASS) theory of intelligence. Results confirmed that this sample of children did not exhibit a specific cognitive style. Rather, there was evidence of a weakness in Successive processing only in the subgroup of poor readers. The importance of understanding the role of Successive processing and rapid naming speed relative to reading is further discussed.     

组织信任氛围对任务绩效的作用途径

通过问卷调查与结构方程建模分析组织信任对于员工工作绩效的影响途径。203名被试和他们的上司参与了问卷调查。结果分析采用潜变量路径分析方法。我们构建多组模型与构思模型,通过两个阶段的检验,分析了组织信任的作用机制。结果表明：组织信任作用于心理安全感,而心理安全感通过两条独立途径影响工作绩效,分别是工作聚焦与工作改进。心理安全感能够促进员工针对工作的不断改进的行为和探索新工作方法的意愿,同时也有利于员工集中精力在工作上,从而提高个人工作业绩     

阅读理解困难儿童的认知加工

阅读理解困难是阅读障碍的一个主要类型,近年来受到西方研究者的重视。阅读理解认知加工,核心是有层次的语义加工,理解困难儿童在词汇语义加工和篇章推理和整合上都存在落后。理解困难儿童的信息推理水平落后,可能原因来自两个方面：一方面是语音工作记忆缺陷导致推理加工能力缺陷,另一方面是阅读元认知缺陷导致阅读目的和理解监控发展不正常。这些缺陷之间复杂的关系,还需要进一步研究     

Which Is in Front of Chinese People,Past or Future? The Effect of Language and Culture on Temporal Gestures and Spatial Conceptions of Time

The temporal‐focus hypothesis claims that whether people conceptualize the past or the future as in front of them depends on their cultural attitudes toward time; such conceptualizations can be independent from the space–time metaphors expressed through language. In this paper, we study how Chinese people conceptualize time on the sagittal axis to find out the respective influences of language and culture on mental space–time mappings. An examination of Mandarin speakers' co‐speech gestures shows that some Chinese spontaneously perform past‐in‐front/future‐at‐back (besides future‐in‐front/past‐at‐back) gestures, especially when gestures are accompanying past‐in‐front/future‐at‐back space–time metaphors (Exp. 1). Using a temporal performance task, the study confirms that Chinese can conceptualize the future as behind and the past as in front of them, and that such space–time mappings are affected by the different expressions of Mandarin space–time metaphors (Exp. 2). Additionally, a survey on cultural attitudes toward time shows that Chinese tend to focus slightly more on the future than on the past (Exp. 3). Within the Chinese sample, we did not find evidence for the effect of participants' cultural temporal attitudes on space–time mappings, but a cross‐cultural comparison of space–time mappings between Chinese, Moroccans, and Spaniards provides strong support for the temporal‐focus hypothesis. Furthermore, the results of Exp. 2 are replicated even after controlling for factors such as cultural temporal attitudes and age (Exp. 3), which implies that linguistic sagittal temporal metaphors can indeed influence Mandarin speakers' space–time mappings. The findings not only contribute to a better understanding of Chinese people's sagittal temporal orientation, but also have additional implications for theories on the mental space–time mappings and the relationship between language and thought.
