2~5岁儿童愿望理解能力的发展

愿望理解是儿童心理理论的重要组成部分.研究选取2~5岁的儿童79名,使用简单愿望推理任务、愿望形成理解任务、冲突愿望理解任务、对自己过去愿望理解任务以及对他人愿望理解任务,系统地探讨愿望理解的层次性.实验结果表明,儿童在对自己过去愿望理解任务中的成绩比简单愿望推理、愿望形成理解和冲突愿望理解中的成绩要好,在冲突愿望理解任务中的成绩比对他人愿望理解的任务要差.说明儿童的愿望理解能力包含着多个方面,其发展步调并不一致,具有一定的顺序性.     

Cognitive Development of Lead Exposed Children from Ages 6 to 15 Years: An Application of Growth Curve Analysis

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.     

Individual Piagetian Epistemological Development of Children from Ages 6 to 11

This long-term study of children from ages 6 to 11 was undertaken to support the patterns of cognitive development inferred from Piaget's work and its short-term statistical replications. Several Piagetian tasks were used individually with 48 first graders, some of the same and new tasks with 43 of the same children as third graders, and two new tasks with 38 of the same children as fifth graders. Pearson product-moment coefficients indicated that uses of the clinical tasks in the study agreed significantly with those in the literature. In 33 individual line graphs, the average age (as indicated in the literature) for the most difficult task performed by a child at each level was compared with the actual age for the child's performance. Although individual aberrations in rates and patterns of cognitive development were observed, the graphic data supported the main hypothesis of the study.     

3～6岁儿童“心理理论”的发展

“心理理论”是发展心理学的研究热点,在儿童获得心理理论的年龄和发展阶段问题上仍存在争议。该研究以3所城市幼儿园中的233名3-6岁儿童为被试,采用“意外转移”和“欺骗外表”两个错误信念测验任务考察儿童“心理理论”的获得年龄和发展阶段。研究得出如下结论:3岁之前儿童已理解外表与真实的区别,但还不能理解错误信念。 4岁儿童理解了欺骗外表任务中自己和他人的错误信念,5岁儿童理解了意外转移任务中的错误信念。4-5岁是儿童获得“心理理论”的关键年龄,但这会因测验任务的不同而有所差异。儿童的错误信念理解不存在显著的性别差异。     

汉语儿童6岁前范畴层次词汇的发展研究

本研究利用个案跟踪语料和控制实验数据,考察了汉语儿童6岁前范畴层次词汇的发展情况。研究表明,基本层次词汇在产出和理解方面均占优势,名词层级的发展主要表现为下位层次词语的增加。儿童对范畴层次词汇的正确产出和理解率从高到低排序依次为基本层次、下位层次和上位层次词汇。本研究为佐证基本层次词语在汉语儿童早期语言发展中占据概念的主导地位提供了经验支持,并支持原型理论对儿童范畴分类能力发展的阐释。     

The Effects of the Family Bereavement Program to Reduce Suicide Ideation and/or Attempts of Parentally Bereaved Children Six and Fifteen Years Later

Findings concerning the long‐term effects of the Family Bereavement Program (FBP) to reduce suicide ideation and/or attempts of parentally bereaved children and adolescents are presented. Parental death is a significant risk factor for suicide among offspring (Guldin et al., 2015). This study is a long‐term follow‐up of 244 children and adolescents who had participated in a randomized trial of the FBP, examining the intervention effects on suicide ideation and/or attempts as assessed through multiple sources. Results indicate a significant effect of the FBP to reduce suicide ideation and/or attempts at the 6‐ and 15‐year follow‐up evaluation. The findings support the potential benefits of further research on “upstream” suicide prevention.     

儿童2~7岁行为抑制性的发展

采用实验室录像观察对中国儿童的行为抑制性的发展进行了追踪研究(2岁、4岁、7岁)。儿童2岁时,有124名儿童参加了实验室观察。儿童4岁时,由于搬迁、退出或失约,有103名儿童参加。儿童7岁时由于以上原因有100名儿童参加实验室观察。在2岁、4岁、7岁至少参加一次观察的儿童有113名,而在三个时间点都参加观察的儿童有89名。我们对儿童2~7岁行为抑制性整体发展的稳定性以及行为抑制性和非抑制性的发展趋向进行了分析。结果表明,中国儿童从2岁到7岁的行为抑制性的整体发展稳定性较低。从2岁到7岁,行为抑制性-非抑制倾向比较稳定的儿童共28人,占总人数的31.5%。而行为抑制性-非抑制性不稳定的儿童为61人,占总人数的68.5%。随着年龄增长,本研究中的儿童的行为抑制性-非抑制性倾向有向中间型趋中的趋势。从2岁到7岁,行为抑制性的发展变化没有显著性别差异     

7～14岁儿童随机性认知的发展

采用三个典型的随机性认知任务(点分布认知,一维分布认知,二维分布认知)系统考察了7~14岁儿童随机性认知的发展特点。结果发现,随机性认知的发展随年龄增长而动态变化,7~10岁表现出上升趋势,而11~14岁表现出下降趋势。点分布认知的发展在7~11岁为缓慢上升,至12~14岁保持稳定。一维分布认知的发展在7~10岁为缓慢上升,在11岁开始迅速下降,至13~14岁趋于稳定。二维分布认知的发展在7~14岁始终处于较低水平。10~11岁是随机性认知发展的重要时期。     

Six Years in the Cognitive and Metacognitive Life of 71 Families

Seventy-one families from a low socio-economic background, each with a son at risk of developing psychosocial problems at the onset of the study, were observed three times over a six-year period while solving a combinatorial task presented on a microcomputer. The permutations task was used to gather information with regard to cognitive functioning and cognitive self-regulation of the families, which were observed as a developmental unit. Cognitive functioning was assessed according to three variables: cognitive strategies, performance, and completion of the task. Six self-regulatory activities were assessed: task definition, planning, supervision, evaluation, parental support, and sharing of responsibilities. Although inefficient strategies were mainly used across the six years, the cognitive level of functioning improved over the years. Cognitive self-regulatory activities most often used across time were supervision and parental support. Differences were observed in the three time periods for supervision, task definition, parental support, and individual involvement. Results indicated a link between cognitive strategies used by the families to solve the task and their self-regulatory activities. Results are interpreted within both the Piagetian and Vygotskian perspectives. Families' cognitive self-regulatory activities observed in this study are an example of parental disengagement and children's growing involvement in a joint activity.     

幼儿自我调控的中日比较及其跨文化分析

实验以中日166名4、5岁幼儿为被试(其中中国幼儿84名,日本幼儿82名),采用故事法比较了中日幼儿在故事情境中的自我调控反应。结果表明:(1)中日幼儿自我调控的反应方式因交往对象的不同表现出了差异。在幼儿与成人的矛盾情境中,日本幼儿比中国幼儿表现出了更多的自我抑制反应,在幼儿与同伴的矛盾情境中,日本幼儿比中国幼儿表现出了更多的自我主张反应;不论在幼儿与成人的矛盾情境中还是在幼儿与同伴的矛盾情境中,中国幼儿都比日本幼儿表现出了更多的依赖成人反应。(2)中日幼儿自我调控的反应方式因情境类型的不同没有表现出差异。不论在幼儿与同伴的矛盾情境中,还是在幼儿与同伴的非矛盾情境中,日本幼儿比中国幼儿表现出了更多的自我主张反应,中国幼儿比日本幼儿表现出了更多的依赖成人和冲动行为反应。     

Suicide Potential and Behavior in Children Ages 4 to 12

ABSTRACT: From a population of 662 children 12 years of age and under, seen at the UCLA Neuropsychiatric Institute, during the years 1970 to 1974, 34 severely depressed children were identified who were also self-abusive and/or suicidal. Case study revealed fragmented, pathological homes, where the children's affect disorders and behaviors were symptomatic of acute family breakdown, marital disharmony, and observed and experienced violence, both verbal and physical. Follow-up on all available children, at least three years posttreatment, revealed that no child had committed suicide. Treatment evaluation by the parents was highly positive, with the great majority of children showing fair to good recovery and adjustment.     

6-12岁儿童抑制能力的发展：来自停止信号任务的证据

利用停止信号任务考察了202名一至六年级小学生抑制能力的发展趋势。被试完成一个视觉上的图形判断任务,在25%的试次中,呈现一个声音信号要求被试抑制反应。以无停止信号下的反应时来衡量反应执行能力,用停止信号反应时（SSRT）来衡量反应抑制能力。结果发现,反应抑制能力随着年龄增长而提高,具体表现为五六年级儿童的抑制能力优于三四年级和一二年级学生的抑制能力。对于反应执行能力,三四年级与一二年级没有差异,而五六年级的成绩显著优于其他年级。结果表明,五六年级儿童的反应执行能力和反应抑制能力都有显著发展。     

The Mental Development of Children

In this study, the author elucidated whether reading experience continues to contribute to word recognition skills in readers with well-internalized reading skills. The participants performed consecutive same or different judgments regarding the identicalness of letters, words, and pseudohomophones. For a more detailed examination of how increased reading experience impacts particular stages of the processing of written stimuli, the author manipulated the identity dimension in each stimuli category. Twenty-five 5th-grade students and 22 university students participated in the study. Overall, findings indicated that a significant development occurs in the recognition of written stimuli after 5th grade because of a shift in the strategic allocation of mental resources (attention) within the recognition process. This change in strategy seems to prompt enhanced retrieval of knowledge relevant to the processing of written stimuli.     

11~14岁超常儿童与普通儿童问题解决能力的发展比较

以北京市某中学和某小学11~14岁之间294名学生为被试, 其中超常儿童131人, 普通儿童163人。采用推箱子任务, 结合横向比较和纵向追踪数据, 从认知能力、元认知能力和认知效率三个维度来考察超常儿童与普通儿童问题解决能力的发展差异。结果发现超常儿童在问题解决能力的三个维度上均优于普通儿童, 两类儿童问题解决能力的发展模式不一致：超常儿童的问题解决能力发展先快后慢, 快速发展期在11~12岁半之间; 普通儿童的问题解决能力发展先慢后快, 快速发展期在12岁半~14岁之间。超常儿童与普通儿童的问题解决能力差异随年龄增大逐渐减小。     

3～5岁幼儿表情认知的发展研究

研究通过"命名复制"、"选择建构"和"自由绘画"三种任务,考察了"嘴""眼""眉"等情绪标签在幼儿情绪识别中的优势效应。结果表明:(1)幼儿识别高兴、悲伤和愤怒要早于惊讶,识别高兴的成绩最好,3～4岁是识别悲伤和惊讶的快速发展期;(2)幼儿识别情绪过程中并未出现典型的"嘴部优势"效应,不同情绪具有不同的代表性的情绪标签,识别高兴和惊讶时嘴部是优势区域,而识别悲伤和愤怒时眼睛和眉毛是优势区域;(3)不同顺序的任务差异显著,先前的情绪命名和复制、建构等任务会显著提高儿童的自由绘画成绩。     

3-5岁儿童汉字方向敏感性的发展

通过Surface Pro触屏电脑呈现知觉匹配任务,记录儿童的主动反应,探查了83名3-5岁学前儿童汉字方向（倒置与镜像）敏感性的早期发展及其与汉字阅读能力的关系。结果发现,4岁儿童可以很好地区分正反方向的汉字,表现出汉字倒置方向的敏感性。但是,各年龄组儿童还未对镜像汉字表现出敏感性。学前儿童对汉字两种方向的认识表现出不同的发展轨迹。学前儿童的汉字倒置方向敏感性与其汉字阅读能力显著相关。     

5～8岁儿童二级信念-愿望推理能力的发展

该研究依据信念(正确-错误)和愿望(接近-回避)对儿童的二级信念-愿望推理能力进行了细分,并据此设计了四个二级信念-愿望任务,探讨了480名5～8岁儿童在四个任务上的表现。结果发现,对儿童而言,不同的二级信念-愿望任务的难度不同,由易到难的顺序依次为:二级真实信念接近愿望、二级错误信念接近愿望、二级真实信念回避愿望、二级错误信念回避愿望。
