The effects of task instructor status on prospective memory performance in preschoolers

The present study applied a 2 × 2 experimental design to assess prospective memory (PM) development across preschool age and to examine the effect of task instructor status (researcher vs. significant other) on PM performance in 80 preschool children. Participants were required to name pictures (ongoing task [OT]), and to remember to refrain from naming but instead give a different response to certain target cues (PM task). Although the OT was of comparable difficulty for both age groups (as indicated by no performance differences), results still indicated significantly higher PM performance in 5-year-olds than in 3-year-olds, confirming the age-related increase of PM capacities between 3 and 5 years. Furthermore, results showed a performance-enhancing effect of significant others as task instructors on both age-groups. Post-hoc analysis revealed that 3-year-olds instructed by a significant other still performed marginally worse than 5-year-olds instructed by a researcher, underlining the finding that substantial changes of PM capacities take place during early childhood.     

Ganging up or sticking together? Group processes and children's responses to text‐message bullying

Drawing on social identity theory and intergroup emotion theory (IET), we examined group processes underlying bullying behaviour. Children were randomly assigned to one of three groups: a perpetrator's group, a target's group, or a third party group. They then read a gender-consistent scenario in which the norm of the perpetrator's group (to be kind or unkind towards others) was manipulated, and an instance of cyberbullying between the perpetrator's group and a member of the target's group was described. It was found that group membership, group norms, and the proposed antecedents of the group-based emotions of pride, shame, and anger (but not guilt) influenced group-based emotions and action tendencies in ways predicted by social identity and IET. The results underline the importance of understanding group-level emotional reactions when it comes to tackling bullying, and show that being part of a group can be helpful in overcoming the negative effects of bullying.

小学儿童算术估算能力的发展

本研究深入考察了我国现阶段小学儿童算术估算能力的发展状况。通过运用自编材料对1027名儿童的团体与个别测试,发现其估算能力的发展具有如下特点：（1）明显受到题目类型的影响,但在不同年龄阶段影响又不尽相同。（2）三年级可能是整数和小数估算能力发展的一个关键期,五年级是发展分数估算能力的较好时期。（3）不同估算策略的发展进程差别相当大,不同时期都有发展的侧重点。（4）小学儿童在估算时易发生多种错误,而且不同年级均有一些典型错误。另外研究还对儿童估算能力、策略与错误类型的发展进行了深入讨论。     

数学焦虑、问题形式对乘法估算的影响

采用由研究者所修订的数学焦虑量表和自行设计的估算问题,通过对大学生被试进行团体测验,考察了在纯数字运算和应用题两种情境中数学焦虑对估算加工的影响以及估算中的问题大小效应。结果显示：（1）数学焦虑情绪在纯数字与应用题两种情境下都对估算有显著影响;（2）情境对估算准确率影响显著,纯数字情境下的估算准确率显著高于应用题情境;（3）在应用题情境估算中发现明显的问题大小效应,在纯数字情境估算中却未发现该效应。     

文明的"早生晚熟"和"晚生早熟"--中、英两国文明特征的比较与反思

本文从经济形态、政治制度、社会结构、思想观念、人格特征五个方面对中英两国文明进行观照,认为中英文明分别具有“早生晚熟”和“晚生早熟”的不同特征,而这又是与双方文明进程迥然、专制程度差异、社会结构有别以及对待传统态度不同分不开的。正是这些差别造成了中华文明从先行到落后,而英国文明虽后来反居上。因此,只有丢掉包袱。轻装上阵。中华民族才能浴火重生。     

亲子依恋、自我概念与大学生自我伤害的关系

以广州市四所高校562名大学生为被试,检验了亲子依恋、自我概念与自我伤害之间关系的三种模型,以讨论其内部关系。结果表明：1）父子依恋和自我概念、母子依恋和自我概念均对自我伤害行为具有保护作用,支持了累加效应模型;2）父子依恋和母子依恋均通过自我概念的部分中介作用对自我伤害产生间接影响,支持了中介效应模型;3）父子依恋和母子依恋对自我伤害的保护作用在低自我概念组中明显,支持了保护因子-保护因子排除假说。     

大学生形成析取概念的假设检验策略研究

运用布鲁纳等人设计的用以研究合取概念的实验材料,研究了大学生形成合取、维度内析取、维度间析取等人工概念的假设检验策略。结果表明,大学生倾向于优先使用单维检验策略（包括单维变化策略和单维肯定策略）。这种策略有利于很快解决合取问题和维度内析取问题,却不利于维度间析取任务的完成,因此大学生解决维度间析取的成功率显著低于合取和维度内析取。     

The influence of norms and social identities on children's responses to bullying

Background. Research on bullying increasingly focuses on social processes, showing that group membership affects children's responses to bullying scenarios. Additionally, correlational research has shown links between norms of cooperation and prosocial behaviour, and between competition and more aggressive forms of behaviour. Aims. This paper focuses on how children's peer group membership affects their group‐based emotions in response to an intergroup bullying incident, and the action tendencies that these emotions predict, in the context of different background norms (for competitive or cooperative behaviour). Sample. Italian schoolchildren, 10–13 years old (N= 128, 65 males) took part in this study. Methods. Participants were randomly assigned to the group of a perpetrator, target, or third‐party group member described in a scenario. Next, they played a game designed to induce a cooperative, competitive, or neutral norm, and read the scenario. They then answered a questionnaire measuring their group‐based emotions. Results. Results underscored the role of norms and group processes in responses to bullying. In particular, children exposed to a cooperative norm expressed less pride and more regret and anger about the bullying than those in other conditions. Conclusions. This study indicates that the influence peer groups have on bullying may be tempered by the introduction of a cooperative normative context to the school setting.
