From blooming,buzzing confusion to media literacy: The early development of television viewing

Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.     

Facilitation by Variation: Right-to-Left Learning of English Yes/No Questions

This study advances the hypothesis that optional structural variation in language facilitates syntactic learning (facilitation‐by‐variation). Support for this is provided by a right‐to‐left‐elaboration acquisition model for English yes/no questions (YNQs). Previous studies have focused on the acquisition of ‘‘inverted’’ YNQs, a cornerstone of nativist theories of language development. Data from five American children (1;3 to 5;1) and their parents show that children hear a range of adult questions (Coming?You coming?Are you coming?), not all inverted. These variants are ordered from structurally least complex noncanonical forms to complex canonical inverted forms. I use state‐of‐the‐art econometric techniques to estimate breakpoints in YNQ time series and show that noncanonical questions emerge early in children’s speech and facilitate acquisition of canonical ones. This incremental structure‐building process relies on an adjunction strategy that augments noncanonical questions with initial auxiliaries and subjects. Development proceeds incrementally from right to left to derive auxiliary‐initial structures.     

Form follows function: Learning about function helps children learn about shape

Object functions help young children to organize new artifact categories. However, the scope of their influence is unknown. We explore whether functions highlight property dimensions that are relevant to artifact categories in general. Specifically, using a longitudinal training procedure, we assessed whether experience with functions highlights shape as important for categorization. Seventeen-month-olds were provided experience with novel categories of similarly shaped objects. In Study 1, the function group learned about the objects’ shape-based functions; a control group did not. In Study 2, 17-month-olds were trained on the same categories, but the objects’ shapes and functions were no longer causally related. Only the function group in Study 1 subsequently used shape reliably when categorizing novel objects. These results suggest that function is instrumental in establishing a ‘shape bias’ in early categorization and that it does so via conceptually based processes.     

Misleading cues improve developmental assessment of working memory capacity: The color matching tasks

The theory of constructive operators was used as a framework to design two versions of a paradigm (color matching task, CMT) in which items are parametrically ordered in difficulty, and differ only contextually. Items in CMT-Balloon are facilitating, whereas items in CMT-Clown contain misleading cues. Participants of ages 7–14 years and adults (N = 149) were studied. We found significant model-predicted graded differences in performance between the facilitating and misleading tasks, across and within age groups, expressing age versus items’ demand interactions. Younger children were differentially affected by contextual cues. Even though both task versions were highly correlated with a well-established developmental measure of attentional capacity, CMT-Clown, which contained misleading cues, was a better measure of working memory capacity. These results show a need to estimate degree of misleadingness whenever performance levels in working memory or mental attention tasks are compared and interpreted. Developmental profiles of both tasks are discussed in terms of contextual differences and neoPiagetian stages of development.     

预防患者术中知哓的早期心理干预——颅内动脉瘤介入栓塞术患者中的研究

探讨早期心理干预在预防颅内动脉瘤栓塞术患者术中知晓的效果。将100例患者按入院先后顺序随机分为观察组和对照组,各50例,均实行整体护理,对照组给予常规的术前、术后护理,观察组在常规护理的基础上给予一系列针对术中知晓的心理护理干预措施。观察组干预前后焦虑程度明显减轻（P〈0．01）,对护理质量满意度均优于对照组（P〈0．05）,差异有统计学意义。针对不同患者心理状态进行系统的早期心理干预可减轻脑血管介入患者术前焦虑情绪,从而积极有效地预防颅内动脉瘤栓塞术患者术中知晓的发生,提高护理质量满意度。     

重症手足口病的早期识别与处理

手足口病(hand-foot-mouth disease,HFMD)是由肠道病毒[以柯萨奇A组16型(Coxsackievirus A16,CoxA16)、肠道病毒71型(Enterovirus 71,EV71)多见]引起的急性传染病,而重症多由EV71感染引起。由于EV71的高度嗜神经性,重症者可合并中枢神经系统(central nervous system,CNS)损害、急性肺水肿/出血等。现就重症手足口病的早期识别与处理进行简要综述。

Self–other awareness and peer relationships in toddlers: gender comparisons

Toddlers' growing self–other awareness has been linked with their ability to interact with peers, but there is reason to think that self–other awareness may relate to different aspects of peer relationships for boys and girls. We hypothesized that boys would express self–other awareness by separating self from other through claiming toys, while girls would express self–other awareness by creating similarities between self and other through use of the duplicate of a partner's toy. For 52 22–26 month olds, self–other awareness was assessed through four tasks: mirror self recognition, perceptual role taking, pronoun recognition and pronoun use. Each child subsequently interacted with a same‐sex peer for 30 min. Girls high in self–other awareness, and their partners were more likely to engage in duplicate toy use than girls low in self–other awareness. No differences in toy claiming were found. Future longitudinal research would clarify how the onset of self–other awareness relates to developments in peer interaction for girls and boys. Copyright © 2010 John Wiley & Sons, Ltd.     

叙述方式、自我视角与自我发展

叙事取向的自我研究认为, 个体在叙述人生故事与回忆自传体记忆的过程中建构与发展自我。新近研究探讨了影响叙事的因素及其对于自我发展的意义, 相关结果显示, 一致性积极叙事、叙事模式、人格特质等与人生故事和自我发展程度存在一致性关系; 一系列实验结果也证明, 回忆自传体记忆时采用的不同视角和不同人称会对个体的情绪、行为和身体生理等产生影响。在此基础上, 研究者应用研究结论进行临床干预, 开展脑神经活动机制等基础研究工作。未来的工作是扩大叙事材料, 更深入探讨影响因素, 如叙事方式和自我视角的跨文化研究。
