Children acquire the later‐greater principle after the cardinal principle

Many have proposed that the acquisition of the cardinal principle (CP) is a result of the discovery of the numerical significance of the order of the number words in the count list. However, this need not be the case. Indeed, the CP does not state anything about the numerical significance of the order of the number words. It only states that the last word of a correct count denotes the numerosity of the counted set. Here, we test whether the acquisition of the CP involves the discovery of the later‐greater principle – that is, that the order of the number words corresponds to the relative size of the numerosities they denote. Specifically, we tested knowledge of verbal numerical comparisons (e.g., Is ‘ten’ more than ‘six’?) in children who had recently learned the CP. We find that these children can compare number words between ‘six’ and ‘ten’ only if they have mapped them onto non‐verbal representations of numerosity. We suggest that this means that the acquisition of the CP does not involve the discovery of the correspondence between the order of the number words and the relative size of the numerosities they denote.

Two‐year‐olds’ understanding of self‐symbols

This study investigated 48 2.5‐year‐olds’ ability to map from their own body to a two‐dimensional self‐representation and also examined relations between parents’ talk about body representations and their children's understanding of self‐symbols. Children participated in two dual‐representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self‐symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self‐symbol task more difficult than the doll‐task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self‐symbol task. The findings demonstrate that 2‐year‐old children have difficulty comprehending a self‐symbol, even when it is two‐dimensional and approximately the same size as them, and suggest that parents’ talk about self‐symbols may facilitate their understanding.     

Children's expectations about training the approximate number system

Humans possess a developmentally precocious and evolutionarily ancient approximate number system (ANS) whose sensitivity correlates with uniquely human symbolic arithmetic skills. Recent studies suggest that ANS training improves symbolic arithmetic, but such studies may engender performance expectations in their participants that in turn produce the improvement. Here, we assessed 6‐ to 8‐year‐old children's expectations about the effects of numerical and non‐numerical magnitude training, as well as states of satiety and restfulness, in the context of a study linking children's ANS practice to their improved symbolic arithmetic. We found that children did not expect gains in symbolic arithmetic after exercising the ANS, although they did expect gains in ANS acuity after training on any magnitude task. Moreover, children expected gains in symbolic arithmetic after a good night's sleep and their favourite breakfast. Thus, children's improved symbolic arithmetic after ANS training cannot be explained by their expectations about that training.     

Meaning in life accounts for the association between long-term ostracism and depressive symptoms: The moderating role of self-compassion

ABSTRACT

According to the temporal need–threat model, ostracism results in three stages of responses. Research on the responses to ostracism has predominantly focused on the first two stages, and the literature needs further empirical evidence on responses to long-term ostracism. We conducted two studies to better understand the association between long-term ostracism and depressive symptoms. Study 1 found a positive association between long-term ostracism and depressive symptoms. More importantly, Study 1 found the threatened sense of meaning in life partially mediates the relationship. Study 2 further found that self-compassion, a positive and healthy trait, weakens the relationship between long-term ostracism and depressive symptoms. More specifically, self-compassion moderates the relationship between the threatened sense of meaning in life and depressive symptoms. Our findings not only further our understanding about the negative consequences of long-term ostracism but also suggest a possible way to mitigate depressive symptoms associated with long-term ostracism.     

The power of the written word: Comparing word meaning inferencing from auditory and written modalities throughout grade school

Previous research indicates that word learning from auditory contexts may be more effective than written context at least through fourth grade. However, no study has examined contextual differences in word learning in older school-aged children when reading abilities are more developed. Here we examined developmental differences in children’s ability to deduce the meanings of unknown words from the surrounding linguistic context in the auditory and written modalities and sought to identify the most important predictors of success in each modality. A total of 89 children aged 8–15 years were randomly assigned to either read or listen to a narrative that included eight novel words, with five exposures to each novel word. They then completed three posttests to assess word meaning inferencing. Children across all ages performed better in the written modality. Vocabulary was the only significant predictor of success on the word inferencing task. Results indicate support for written stimuli as the most effective modality for novel word meaning deduction. Our findings suggest that the presence of orthographic information facilitates novel word learning even for early, less proficient readers.     

不同适应水平小学生情绪体验评价比较--关于小学生自我调节机制的一项研究

本研究选取发展良好与适应不良的三－－五年级小学生为被试，用问卷形式向他们呈现各种情景，要求被试评价自己对情景的情绪体验。通过比较分析两组被试的情绪评价得分，揭示被试的主观意义特征。被试的反应显示，两组被试之间存在着内部强化机制差异和交往价值取向差异，适应不良学生表现出对负性意义敏感和表达的淡化。     

Language knowledge and event knowledge in language use

This paper examines how semantic knowledge is used in language comprehension and in making judgments about events in the world. We contrast knowledge gleaned from prior language experience (“language knowledge”) and knowledge coming from prior experience with the world (“world knowledge”). In two corpus analyses, we show that previous research linking verb aspect and event representations have confounded language and world knowledge. Then, using carefully chosen stimuli that remove this confound, we performed four experiments that manipulated the degree to which language knowledge or world knowledge should be salient and relevant to performing a task, finding in each case that participants use the type of knowledge most appropriate to the task. These results provide evidence for a highly context-sensitive and interactionist perspective on how semantic knowledge is represented and used during language processing.     

Introduction What aptitudes,values, and behaviors for an already present future?

Abstract

Evolution, in particular demographic growth, and progress in the world of science and technology, has led to deep‐seated transformations on economic, social and political levels. How are we to teach the young to build the 21st century in the most suitable way? What are the values, what are the aptitudes and behaviors which will enable them to flourish as actors on the stage of a changing, complex and uncertain world?
