学习者生成图解对说明文阅读理解和应用的效果

在112名大学生被试阅读难度不同的两种材料并解答相关的理解题和应用题时,按照阅读时是否要求生成图解与答题时是否允许生成图解两个条件将他们平均分为四个小组,探讨阅读画图与答题画图对被试理解和应用不同难度材料的影响。结果表明,阅读时学习者生成的图解可显著促进对难度较高材料的理解;答题时学习者生成的图解可显著促进对难度较低材料的应用;阅读时是否画图与答题时是否画图对理解和应用所学习材料没有显著交互作用。     

Are people always more risk averse after disasters? Surveys after a heavy snow‐hit and a major earthquake in China in 2008

China suffered both a heavy snow‐hit and a major earthquake in 2008. To investigate the effects of disasters on risky decision making, opportunity samples were obtained by recruiting residents in both devastated and non‐devastated areas. In a survey (Study 1) conducted shortly after the heavy snow‐hit, we found that people were not always more risk averse after a disaster as previous studies had claimed and that they were inclined to approach an option with ‘low probability associated gain’ and to avoid an option with ‘low probability associated loss’. These findings were replicated in a consecutive survey (Study 2) conducted after the Wenchuan earthquake. It was further found that the popularity of both insurance and lottery, which presumably contributed to overweighing of small probabilities, was detected to have been enhanced with substantial exposure to the earthquake disaster. The implications of these findings for risk education and government policy making were discussed. Copyright © 2009 John Wiley & Sons, Ltd.

言语和非言语信号加工的早期分离——来自ERP研究的证据

利用128导事件相关电位技术,对19名正常被试在言语、峰鸣声和音乐刺激上产生的脑电早期外源性成分N1进行了考察。实验结果发现,在音素条件和蜂鸣声条件下,左侧额叶N1波幅显著高于右侧。偶极子溯源分析发现音素条件和蜂鸣声条件下的偶极子都位于左脑额叶,而音乐条件下的两个偶极子位于右脑额叶。证明范畴属性对信号加工大脑半球优势的影响在加工的早期就开始发挥作用。

Phonological awareness in young Chinese children

Two studies explored the nature of phonological awareness (PA) in Chinese. In Study 1, involving 146 children, awareness of phoneme onset did not differ from chance levels at ages 3-5 years in preschool but increased to 70% correct in first grade, when children first received phonological coding (Pinyin) instruction. Similarly, tone awareness was at better than chance levels from second year kindergarten (age 4), but increased strongly and significantly in first grade to 74% accuracy. In contrast, syllable and rime awareness increased gradually and steadily across ages 3-6 years. Patterns suggest different influences of age and literacy instruction for different PA levels. In Study 2, involving 202 preschoolers, variance in Chinese character recognition was best explained by tasks of syllable awareness, tone awareness, and speeded naming. Findings underscore the unique importance of both tone and syllable for early character acquisition in Chinese children.     

Reading proficiency modulates parafoveal processing efficiency: Evidence from reading Chinese as a second language

In the present study, we manipulated different types of information available in the parafovea during the reading of Chinese sentences and examined how native Korean readers who learned Chinese as a second language make use of the parafoveal information. Results clearly indicate that, only identical and orthographically similar previews facilitated processing of the target words when they were subsequently fixated. More critically, more parafoveal information was obtained by subjects with higher reading proficiency. These results suggest that, mainly low-level features of the parafoveal words are obtained by the non-native Chinese readers and less attentional resources are available for the readers with lower reading proficiency, thereby causing a reduction of the perceptual span.     

50% off or buy one get one free? Frame preference as a function of consumable nature in dairy products

Previous studies on how framing differentially affects consumer perceptions of value from equivalent deals indicate that perceptions of deal value from price-saving versus extra-product promotions are moderated by the stock-up characteristic of the category. In this study, the authors explored the relationship between stock-up characteristic and frame preference and the influence of the consumable nature of goods on frame preference. An experiment involving 223 student participants showed that consumable nature, but not stock-up characteristic, affected frame preference. The authors discuss the implications of this finding for the study of information framing and how it impacts consumer judgment and decision making.     

阅读障碍儿童的语言特异性认知缺陷

以41名五六年级的阅读障碍儿童和41名正常儿童为研究对象,系统考察了语言认知能力和一般认知能力与阅读成绩之问的关系.结果发现,障碍儿童在所有的语言认知测验中显著落后于正常儿童,较高比率的儿童存在能力缺陷.而在非语言特异性的一般认知能力测验中,未发现两组存在显著差异的证据,这意味着阅读障碍儿童的认知能力缺陷主要集中在语言认知领域.
