从《论语》探析孔子素质教育思想的现代理论价值

人们普遍认为“素质教育”是一种新的教育模式,其实,早在两千多年前孔子就比较全面地提出了素质教育思想。《论语》正是孔子这一思想的集中体现。本文从教育对象、教育内容、教育方法诸方面总结孔子的素质教育思想,以利于深刻地理解素质教育的内涵,推进教育教学改革。     

Life-long environmental enrichment differentially affects the mnemonic response to estrogen in young, middle-aged, and aged female mice

The present study was designed to examine whether life-long exposure to standard or enriched housing affects the ability of estrogen to improve spatial and object memory throughout the lifespan. Three-week-old female mice were maintained in standard or enriched housing up to and through ovariectomy and behavioral testing at 5, 17, or 22 months of age. Spatial memory was tested in the Morris water maze and object memory was tested using an object recognition task. Immediately after training each day, mice were injected intraperitoneally with vehicle or 0.2 mg/kg 17beta-estradiol. Among young females, object recognition was enhanced by estradiol alone, an effect that was reduced by enrichment. In contrast, spatial water maze performance was impaired by estradiol alone, but improved by the combination of both estradiol and enrichment. At middle-age, object recognition was enhanced by estradiol or enrichment alone, and the combination of both treatments. Spatial memory in the water maze was also improved by both treatments at middle-age, but the beneficial effects of estradiol were limited to standard-housed females. Finally, whereas enrichment in aged females significantly enhanced performance in both tasks, estradiol had no effect at this age in either task. In total, the data indicate that life-long enrichment can significantly alter the extent to which estradiol affects memory in mice throughout the lifespan. Importantly, the interaction between these treatments is highly dependent on age and type of memory tested.     

Preference for impossible figures in 4-month-olds

Can infants use interposition and line junction cues to infer three-dimensional (3D) structure? Previous work has shown that in a task that required 4-month-olds to discriminate between static two-dimensional (2D) pictures of possible and impossible cubes, infants exhibited a spontaneous preference for displays of the impossible cube but left open the question of whether they did so on the basis of purely local “critical regions” or whether they were able to employ more global clues. Here infants were presented with possible and impossible cubes in which the strictly local cues that could have derived from exterior binding contours were deleted. Results showed that infants were still able to discriminate possible cubes from impossible cubes, suggesting that longer looking infants are sensitive to global properties and that the capacity to integrate pictorial information to perceive aspects of global 3D shape may develop earlier than demonstrated previously using reaching tasks.     

Bias for consonantal information over vocalic information in 30-month-olds: cross-linguistic evidence from French and English

Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at the lexical level. In the current study using the same task, we first show that by 30 months French-learning infants can make use of one-feature vocalic contrasts (e.g., /pize/–/pyze/). Second, we show that in a situation where infants must neglect either a consonantal one-feature change or a vocalic one-feature change (e.g., match a /pide/ with either a /tide/ or a /pyde/), both French- and English-learning 30-month-olds choose to neglect the vocalic change rather than the consonantal change. We argue that these results suggest that by 30 months of age, infants still give less weight to vocalic information than to consonantal information in a lexically related task even though they are able to process fine vocalic information.     

Attachment representations in mothers of preterm infants

The aim of the study was to assess attachment representations in mothers of preterm infants using the Working Model of Child Interview (WMCI) at the 12 months of the infant's corrected age. In addition, the relation between WMCI representation categories and the Edinburgh Postnatal Depression Scale score at 6 months of the infant's corrected age was studied. There were 38 mothers of preterm infants (<1500 g or <32 gestational weeks) and 45 mothers of full-term infants. The results showed no differences between the study groups in the distribution of the three main representation categories (balanced, disengaged and distorted). However, there were qualitative differences in representations between the groups. Furthermore, maternal depression symptoms were associated with distorted representation category. We suggest that despite the qualitative differences in the mothers’ representations, mothers of preterm infants are as likely to form balanced attachments with their infants as mothers of full-term infants.     

An empirical and computational investigation of perceiving and remembering event temporal relations

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.     

Rethinking NIMBYism: The role of place attachment and place identity in explaining place‐protective action

The ‘NIMBY’ (Not In My Back Yard) concept is commonly used to explain public opposition to new developments near homes and communities, particularly arising from energy technologies such as wind farms or electricity pylons. Despite its common use, the concept has been extensively critiqued by social scientists as a useful concept for research and practice. Given European policy goals to increase sustainable energy supply by 2020, deepening understanding of local opposition is of both conceptual and practical importance. This paper reviews NIMBY literature and proposes an alternative framework to explain local opposition, drawing upon social and environmental psychological theory on place. Local opposition is conceived as a form of place‐protective action, which arises when new developments disrupt pre‐existing emotional attachments and threaten place‐related identity processes. Adopting a social constructivist perspective and drawing on social representation theory, a framework of place change is proposed encompassing stages of becoming aware, interpreting, evaluating, coping and acting, with each stage conceived at multiple levels of analysis, from intrapersonal to socio‐cultural. Directions for future research and potential implications of the place‐based approach for public engagement by energy policy‐makers and practitioners are discussed.

要点表征与字词表征在错误再认中的作用

关键诱词是指在学习中没有出现的、跟所学单词有一定关联的词。学习者对关键诱词提取时错误再认率(即虚报率)较高,这被称之为错误再认现象。有人认为是要点表征导致了错误记忆,但也有人认为记忆中是字词表征起主要作用。本研究针对要点表征和字词表征对中学生英语单词学习中错误再认的影响进行了2×7的混合设计,分别考查了分类分组呈现单词和随机呈现单词对中学生英语单词再认的影响,同时考查了关键诱词的虚报率与学习次数的关系。发现:(1)学习分类分组呈现单词的被试,对关键诱词的虚报率明显高于学习随机呈现单词的被试,说明要点表征在错误再认中起着重要作用;(2)对关键诱词的虚报率与学习次数之间呈现倒V型的关系,说明在学习初始阶段,要点表征在错误再认中起主要作用;但在学习的后期,字词表征在再认中的作用占据了主要地位。     

行动的认知表征水平

个体行动认知表征水平是与个人的行动而非一般心理功能具有特定关联的思维风格。它是一个80年代后兴起的研究领域。本文围绕行动认知表征水平研究的背景、认知表征水平与行动的交互作用以及行动认知表征水平的个体差异展开介绍。文章最后讨论了该研究的不足。
