Multifactorial pathways facilitate resilience among kindergarteners at risk for dyslexia: A longitudinal behavioral and neuroimaging study

Recent efforts have focused on screening methods to identify children at risk for dyslexia as early as preschool/kindergarten. Unfortunately, while low sensitivity leads to under‐identification of at‐risk children, low specificity can lead to over‐identification, resulting in inaccurate allocation of limited educational resources. The present study focused on children identified as at‐risk in kindergarten who do not subsequently develop poor reading skills to specify factors associated with better reading outcomes among at‐risk children. Early screening was conducted in kindergarten and a subset of children was tracked longitudinally until second grade. Potential protective factors were evaluated at cognitive‐linguistic, environmental, and neural levels. Relative to at‐risk kindergarteners with subsequent poor reading, those with typical reading outcomes were characterized by significantly higher socioeconomic status (SES), speech production accuracy, and structural organization of the posterior right‐hemispheric superior longitudinal fasciculus (SLF). A positive association between structural organization of the right SLF and subsequent decoding skills was found to be specific to at‐risk children and not observed among typical controls. Among at‐risk children, several kindergarten‐age factors were found to significantly contribute to the prediction of subsequent decoding skills: white matter organization in the posterior right SLF, age, gender, SES, and phonological awareness. These findings suggest that putative compensatory mechanisms are already present by the start of kindergarten. The right SLF, in conjunction with the cognitive‐linguistic and socioeconomic factors identified, may play an important role in facilitating reading development among at‐risk children. This study has important implications for approaches to early screening, and assessment strategies for at‐risk children.     

The Relation of Career Adaptability to Work–Family Experience and Personal Growth Initiative Among Taiwanese Working Parents

This study aimed to explore the effect of career adaptability on 598 working parents in Taiwan. The results showed that career adaptability served an important role in moderating and mediating the effects between work–family conflict, work–family strength, and personal growth initiative.     

Karma or Immortality: Can Religion Influence Space‐Time Mappings?

People implicitly associate the “past” and “future” with “front” and “back” in their minds according to their cultural attitudes toward time. As the temporal focus hypothesis (TFH) proposes, future‐oriented people tend to think about time according to the future‐in‐front mapping, whereas past‐oriented people tend to think about time according to the past‐in‐front mapping (de la Fuente, Santiago, Román, Dumitrache, & Casasanto, 2014). Whereas previous studies have demonstrated that culture exerts an important influence on people's implicit spatializations of time, we focus specifically on religion, a prominent layer of culture, as potential additional influence on space‐time mappings. In Experiment 1 and 2, we observed a difference between the two religious groups, with Buddhists being more past‐focused and more frequently conceptualizing the past as ahead of them and the future as behind them, and Taoists more future‐focused and exhibiting the opposite space‐time mapping. In Experiment 3, we administered a religion prime, in which Buddhists were randomly assigned to visualize the picture of the Buddhas of the Past (Buddha Dipamkara) or the Future (Buddha Maitreya). Results showed that the pictorial icon of Dipamkara increased participants' tendency to conceptualize the past as in front of them. In contrast, the pictorial icon of Maitreya caused a dramatic increase in the rate of future‐in‐front responses. In Experiment 4, the causal effect of religion on implicit space‐time mappings was replicated in atheists. Taken together, these findings provide converging evidence for the hypothesized causal role of religion for temporal focus in determining space‐time mappings.

6～12岁儿童脑电α波频率分布特点与信息加工速度的关系

本研究以 2 2 8名 6～ 12岁儿童为研究对象 ,采用脑电波超慢涨落分析技术 (简称ET) ,重点探讨了与认知功能有关的α波 ( 8～ 13Hz)的分布特点。研究结果表明 :①α波在全脑 12个脑区的比率 ,因频率成分不同而表现出不同的分布特点 ;②α波在左右对称脑区的分布比率也因频率不同而表现出不同的左右脑优势。除左前颞叶的平均频率显著大于右前颞叶外 ,其他左右脑对称区域的平均频率的差异均不显著。α波平均频率的从高到低依次为枕叶、中央区、顶叶、左前颞叶、后颞叶、额叶、右前颞叶 ;③信息加工速度与α波的关系并不明显 ,快组和慢组被试的 6种频率 ( 8～13Hz)α波的比率均无显著性差异     

Culture and perceptions of self—other similarity

In testing possible cultural effects of the use of the self as an habitual reference point to which others are compared, we expected that: (a) individualistic participants (i.e., those who give priority to personal goals) would rate self—other similarity higher when asked “How similar is X to you?” than when asked “How similar are you to X?”, whereas nondirectional similarity judgements (“How similar are these two people?”) would resemble the former directional comparison; (b) collectivistic participants (i.e., those who give priority to in‐group goals) would show a weaker or, possibly, reversed pattern, especially using in‐group comparison others. Neither hypothesis was upheld. However, the individualists perceived the in‐group to be relatively more similar to themselves as compared to the collectivists. This difference cannot be explained by response bias, status asymmetry, or role differentiation. We propose an explanation in terms of the differential relationship between self and other representations for people from collectivist versus individualist cultures.     

Quantum mechanics and violations of the sure-thing principle: The use of probability interference and other concepts

The use of quantum mechanical concepts in social science is a fairly new phenomenon. This paper uses one of quantum mechanics’ most basic concepts, probability interference, to explain the violation of an important decision theory principle (the ‘sure-thing principle’). We also attempt to introduce other quantum mechanical concepts in relation to the sure-thing principle violation.     

代谢综合征与乳腺癌

研究显示,代谢综合征可增加女性乳腺癌的患病风险,在绝经后妇女中表现更明显。这种作用可能通过胰岛素抵抗影响雌激素和性激素结合球蛋白水平、高胰岛素血症的直接或间接作用以及脂肪因子水平异常等机制实现。因此,对于我国乳腺癌发病率可能随代谢综合征人群不断扩大而上升的趋势应予以足够重视。
