Talking about others facilitates theory of mind in Chinese preschoolers

A longitudinal study and a training study were conducted to show that simply referring to others facilitated theory of mind (ToM) development in Chinese children. In Study 1, 3- to 4-year-old Chinese children (N = 52) were tested on ToM and autobiographical memory (AM). One year later, in the group of children who initially failed the false belief tasks, only those who increased their references to others in AM recall passed the tasks. In Study 2, Chinese preschoolers who were trained to talk about others through storytelling showed improvement in their ToM performance. These findings suggest alternative pathways for ToM development in non-Euro-American context.     

Performance-based adaptive schedules enhance motor learning

Although investigators have shown that random scheduling of several tasks enhances learning more than blocked scheduling does, the advantages of random scheduling may be limited because it does not take into account the nominal difficulty of each task, the difference in difficulty between tasks, and the skill level of the learner in that type of schedule. The authors propose 2 new algorithms for adaptively determining the nominal difficulty and the number of trials for each task on the basis of both current and delayed performance of the learner (N = 48). The authors tested the adaptive algorithms in a 2 x 2 factorial design, and they show that the algorithms outperform random scheduling when performance is measured on a delayed retention test.     

When we feel good and bad about ourselves: self-esteem memories across cultures

Young adults in the United States, Croatia, and China described personal episodes of times when they felt especially good or bad about themselves. These self-esteem memories were either recent (episodes that occurred during the previous 4 weeks) or remote (episodes that occurred between the ages of 10 and 15). Systematic content differences between memories of positive and negative self-worth were apparent primarily for remote rather than for recent memories. Across cultures, long-lasting positive memories frequently represented achievement themes, whereas negative memories frequently represented social themes. Links between achievement success and positive self-regard, and between social distress and negative self-regard, are explained using theories of self-esteem and autobiographical memory.     

汉语母语者视听双通道言语知觉的特点及发展研究

以30名小学二年级学生2、4名小学五年级学生和29名大学一年级学生为被试,运用McGurk效应研究范式对汉语母语者视听双通道言语知觉的表现特点、发展趋势等问题进行了探讨,三个年龄阶段被试均接受纯听和视听两种条件下的测查,被试的任务是出声报告自己听到的刺激。结果发现:(1)汉语为母语的二年级小学生、五年级小学生和大学生在自然听力环境下的单音节加工中都受到视觉线索的影响,表现出了McGurk效应;(2)二年级小学生、五年级小学生和大学生受视觉言语影响的程度,也就是McGurk效应的强度没有显著差异,没有表现出类似英语母语者的发展趋势。该结果支持了McGurk效应"普遍存在"的假说。     

正误样例组合学习的相似性效应和认知加工深度效应

为了考察物体受力分析图正、误样例的相似程度以及被试对错误受力分析的认知加工(即对错误受力分析的辨别、解释和改正)水平对物体受力分析规则正误样例组合学习迁移效果的影响,以初中三年级学生为被试进行两项实验研究。实验结果表明:在物体受力分析图正误样例组合学习中存在明显的相似性效应,即正、误样例的相似程度越高,学习迁移的效果越好;对错误受力分析进行"改正"加工的学习迁移效果明显优于对错误的"辨别"加工,即存在明显的认知加工深度效应。     

中小学教师工作重塑问卷的编制

在文献分析和专家评定的基础上,从重塑的对象与方式出发,通过半结构化访谈和问卷调查,编制了初始的中小学教师工作重塑问卷。通过探索性因素分析和验证性因素分析对初始问卷进行修订,最终形成的正式问卷包含五个维度：任务重塑、角色重塑、关系重塑、技能重塑和认知重塑。结果表明,中小学教师工作重塑问卷具有较高的内部一致性信度、重测信度以及较好的内容效度、结构效度和效标效度。该问卷的心理测量学指标良好,可以作为我国中小学教师工作重塑的测量工具。     

关于小学教师对学生课堂参与的内隐观的研究

本研究通过课堂观察和结构化访谈,从三个侧面,即：教师判断学生参与的标准、对学生参与特点的描述、对参与功能的界定,考察了49名小学教师对学生课堂参与的内隐认识。研究表明,教师：1)重视师生交往中学生的参与,忽视学生与同学间的交往和学生独立活动时的表现;2)最关注学生在行动上的参与,其次是学生思维的投入,对学生情绪的投入是比较忽视的;3)特别注重参与促进学生认知能力发展的功能。     

3、4岁儿童数数的规则及其策略运用的研究

数数能力是儿童用于建构其数学知识系统的重要工具,是儿童早期获得的最基本的数认知能力之一。本研究以234名3、4岁儿童为被试,采用个别测查法对儿童数数的规则及其策略运用进行了考察。研究发现：(1)随着数列数目的增大,3、4岁儿童数数精确性呈下降趋势,但4岁儿童在各项任务上的数数精确性显着高于3岁儿童;(2)3、4岁儿童在数7、10、15、30任务上的错误表现有显着差别;(3）3、4岁儿童数数策略运用存在显着差别．协方差分析显示。策略使用在数7和数10任务上具有显着效应。     

自然事物认知偏好的初步实验研究

本研究从认知心理学角度采用实验方法探索自然科学学习的影响因素。发现：1自然事物的认知偏好中存在内隐学习现象。2．自然事物认知偏好的表现非常复杂：年龄的影响并不显著,经验的影响不可忽视;3．性别差异十分明显,男生比女生的自然事物认知偏好更为肯定更为积极,很可能社会性别角色是造成自然科学学习结果差异的重要原因;4．内隐组学习坦率好奇,倾向于把自然事物看得更熟悉更容易,具有更强的探究兴趣：外显组学生矜持审慎,倾向于把自然事物看得更陌生更难以理解,探究兴趣较弱。因此,科学教育要创设情境让学生潜移默化地学以致用;要帮助学生利用经验并从中获取乐趣、增长兴趣、树立志趣;要鼓励女孩子大胆挑战科学。     

初中生饮酒期望及其与饮酒行为关系的研究

本研究通过对 1 73 4名初中生的问卷测查 ,考察了当前初中生饮酒期望的性别和年级差异 ,并进一步探讨了饮酒期望与饮酒行为之间的关系。结果表明 :( 1 )初中男生的饮酒积极期望和女生相比没有明显差异 ,但饮酒的消极期望显著低于女生 ;( 2 )随着年级的升高 ,初中生的饮酒积极期望和消极期望都呈降低的趋势 ;( 3 )性别、年级、饮酒积极期望和饮酒消极期望对于饮酒行为都有显著的作用 ,饮酒消极期望对于饮酒行为的解释率要高于饮酒积极期望 ;( 4)饮酒消极期望对于饮酒积极期望和饮酒行为的关系有重要的调节作用。
