4~7岁儿童对生物目的指向性的认知发展模式

采用结构式访谈法,通过计算机模拟真实情景的动画方式,系统探查4~7岁儿童在目的指向性维度上的本体区分、因果认知发展模式以及在此维度上的朴素生物学“理论”的形成。结果表明：（1）4~7岁儿童在目的指向性维度上进行本体区分的认知发展模式,经历了从低到高的4个发展水平,即目的论模式——基于动物模式——基于生物模式——基于本体区分模式;（2）4~7岁儿童对目的指向性的因果认知与本体区分表现出一致性发展模式,表明学前儿童在目的指向性维度上逐渐形成了朴素生物学“理论”;（3）5~6岁是儿童对目的指向性认知的快速发展期,领域知识对儿童的认知发展具有明显的促进作用,但是受年龄和领域任务的影响     

学前儿童“朴素生物学理论”发展的实验研究──对“生长”现象的认知发展

从学前儿童对生物生长现象的认知入手探查了学前儿童朴素生物学理论的发展,探查了发展中的个别差异和个体内部差异。研究发现：（１）学前儿童在生长维度上逐渐形成了朴素生物学理论;（２）不同教育条件下的儿童对生长的认知存在差异;学前早期儿童的认知成绩更多地受实验任务变式的影响,而学前晚期儿童的个体内部差异则较小。     

学前儿童对生物衰老的认知

按照“朴素理论”的要素设计研究任务,研究一探查学前儿童能否以衰老这一生命特征为标准做出生物和非生物的本体区分,以及能否对衰老做出生物性而非意图的因果解释;研究二进一步探查学前儿童对生物衰老特性（普遍性和不可逆性）的认知。结果显示,4、5、6岁学前儿童在分类作业中的认知成绩随年龄逐渐提高,而在因果解释中,各年龄组儿童都不用心理意图作为衰老的原因;他们对衰老的认知与其对生长的认知密不可分;学前儿童对衰老两个特性的认知不同步;由研究结果可以推论,6岁儿童在衰老维度上具有了较稳定的朴素生物理论。     

4-7岁儿童关于动物繁殖的朴素生物学理论的发展

以128名4、5、6、7岁儿童为被试,采用访谈和分类任务从亲代、子代两个维度探查儿童依据繁殖对动物和非生物的本体区分及因果解释,并进一步探查对繁殖的“成熟后发生”和“代代衍生”的认知。结果显示,4-7岁儿童关于动物繁殖的朴素生物学理论的发展经历了萌芽认识、部分掌握、基本掌握和成熟稳定4个阶段,6岁儿童基本掌握了动物繁殖概念,并能对之进行一致的生物学的因果解释。对动物繁殖认知的个体内差异表现为：①对动物、非生物领域的认知因任务要求而表现不同;②任务形式对发展快速期的5、6岁儿童影响显著;③儿童理解“成熟后发生”优于理解“代代衍生”,理解“向下衍生”优于理解“上溯来源”。     

儿童反语理解的心理机制

反语是指使用与本意相反的字面形式表达本意的一种修辞形式,在儿童言语发展领域中是一种难度较大的认知对象。该对儿童在反语理解任务中的困难根源进行了探讨,介绍了目前关于儿童反语理解的心理机制研究的两种主要途径,一是采用成人反语识别理论去解释儿童反语理解的心理过程,二是从二阶心理理论角度开展的解释儿童反语理解的心理机制的尝试,最后在暗示假装理论和二阶心理理论的框架下对现有的研究证据进行了整合的讨论,并对未来研究提出了建议。     

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。     

儿童经济学认知的发展

儿童经济学认知发展的研究是儿童认知发展研究中的新领域。文章主要介绍了发展心理学家在皮亚杰“阶段论”和目前新兴的“朴素理论”两大理论阵营中的研究成果和进展,并从理论和实践两方面阐述了开展儿童经济学认知研究的重要意义。     

儿童科学概念的认知发展

综述了作者在儿童科学概念认知领域的研究,其中包括儿童的朴素生物学、朴素物理学认知及其与心理理论发展关系的研究。作者研究了儿童在生命科学领域的自发概念,包括对生长、衰老、疾病和死亡等生命现象的认知,探查儿童对日常生活中物理学概念（如力等）的朴素认知,力图发现儿童早期认知中的潜力,同时探明他们相应的错误概念,并采用教育干预实验,促进儿童科学概念的转化。还探查影响儿童科学概念发展的因素,包括外部教育条件以及个体认知能力（如心理理论发展水平,推理能力等）。研究发现,儿童在接受正规的科学教育前就对人类重要的科学领域形成了自己的“朴素理论”,他们用这种理论来解释现实世界的现象。作者主张儿童的科学教育（包括健康教育）应该以儿童的“朴素理论”为基础,从而真正做到因材施教

关于儿童数学认知策略的理论与实证研究

儿童数学认知策略是当前认知发展领域的重点研究方向之一.在认知策略的发展形态上,凯斯提出的阶梯模型受到了希格勒重波模型的挑战,陈英和等的研究证实了后者关于策略发展多样性与渐进性的观点;儿童数学认知策略的选择在不同题目类型与任务情境之间,表现出了鲜明的适应性特点;而数学焦虑、工作记忆及概念性理解等是影响儿童数学认知策略选择和执行的重要因素,这些研究为进一步探明儿童数学认知策略的发展规律提供了证据.     

Effects Of Histories Of Differential Reinforcement Of Response Rate On Variable-interval Responding

Three pigeons were exposed first to multiple differential-reinforcement-of-high-rate and differential-reinforcement-of-low-rate schedules that were correlated with green and red keys, respectively, and then were shifted to a variable-interval schedule arranged on a white key. In subsequent test sessions, the variable-interval schedule continued to operate, but green and red keys replaced the white key in alternate sessions. In Part 1 of the experiment, the variable-interval schedule correlated with the white key was introduced immediately after the multiple-schedule condition, and the test condition began 15 days later. This sequence was repeated twice, with a reversal of the correlation of the key colors with the components of the multiple schedule at the start of each new cycle. Part 2 added a 6-month break between the multiple-schedule history and the white-key variable-interval schedule followed by test sessions. The procedure was then repeated with a reversal of the correlation between key colors and multiple-schedule components. In the test sessions of Part 1, all pigeons consistently responded faster in the presence of the key color most recently correlated with the differential-reinforcement-of-high-rate contingency than during the color most recently correlated with the differential-reinforcement-of-low-rate contingency. Similar but smaller effects were observed in Part 2. The effects of the reversals in these two parts of the experiment showed that only the most recent contingency exerted an influence on subsequent responding. The data suggest that this effect of the most recent history continues to operate on behavior under current contingencies even after a long lapse of time.

The Hypothesis Of Ether And Reid's Interpretation Of Newton's First Rule Of Philosophizing

My object is to question a recurrent claim made to the point that Thomas Reid (1710–1796) was hostile to ether theories and that this hostility had its source in his distinctive interpretation of the first of Newton's regulæ philosophandi. Against this view I will argue that Reid did not have any quarrel at all with unobservable or theoretical entities as such, and that his objections against actual theories concerning ether were scientific rather than philosophical, even when based on Newton's first rule. I argue further that Reid's insistence on Newton's rule concerns, not direct observation, but rather the notion of explanation itself.     

Comparison Of Narratives Of Loss Experiences Of World War Ii and Vietnam Combat Veterans

Abstract

While their continuing grief now is receiving periodic media attention, for years and even decades, American soldiers who fought in World War II (WWII) and who fought in Vietnam have suffered their life-altering experiences of loss in silence. Many of the WWII generation now have died and cannot share their grief with us. We as scholars of loss and trauma have a special obligation to reach out to the living survivors of WWII for information about their experiences. As has been often noted (e.g., Kuenning, 1990), for years after the conclusion of the Vietnam War, the stories of loss and grief of Vietnam veterans were not welcomed. The purpose of this chapter is to report some comparative narrative evidence from veterans of these two wars. Our major question was whether strong differences between groups in perceived long-term impact of combat experience would be reported.     

Some Characteristics Of The G Index Of Agreement

Several uses of the G index of agreement are discussed for both Q- and R-techniques. It is shown that the index is meaningful and is not sensitive either to changes in having direction (for profile analysis) or to marginal inequalities for dichotomous data.     

Loss Of Trust: Correlates Of The Comorbidity Of Ptsd and Severe Mental Illness

Abstract

The prevalence of post-traumatic stress disorder (PTSD) in the general population of the United States is a topic of speculation, with estimates ranging from 0.4% to 9% (Breslau, Davis, Andreski, & Peterson, 1991; Helzer, Robins, & McEvoy, 1987; Kessler, Sonnega, Bromet, Hughes, & Nelson, 1995). Likewise, estimates of the prevalence of PTSD within the population of persons with serious mental illness have varied widely, depending on how PTSD has been measured. While record verification of PTSD within mental health outpatient samples has routinely been very low (0%-3%), research assessments of PTSD have resulted in estimated rates of co-occurrence of 29% to 43% (Cascardi, Mueser, DeGirolomo, & Murrin, 1996; Craine, Henson, Colliver, & MacLean, 1998; Mueser et al., 1998). A lack of documentation of PTSD in clinical records and inattention to PTSD in clinical diagnoses are thought to greatly underestimate the extent of PTSD within mental health treatment populations. The general consensus among researchers has been that the occurrence of PTSD is much higher within the population of persons with diagnoses of mental illness than in the general population, particularly among those who have major depression (Friedman & Rosenheck, 1996).
